    15 20 25 30 35 2 voltage setting. The increase in force must thus take place linearly and the diagram in Figure 1 shows how this linear increase takes place. The vertical scale shows the force generated in the elastic member and the horizontal scale shows the deformation of the elastic member when it is tensioned and the straight line in the diagram shows the linear relationship between force and deformation.
    When a normal user ties his hand, he generates a force having the appearance shown by the curve line in the diagram in Figure 1. In this case, the vertical axis shows the force generated and the horizontal axis how much movement the hand performs. As can be seen from this, the increase in force does not take place completely linearly.
    This difference between the linear force increase shown in Figure 1 with the straight line and the force increase shown with curve line one in Figure 1 means that the arrangement should be so designed that there is a synchronization between the force generation of the hand and the force generation required to energize it. elastic body. However, only very limited such synchronization occurs in previous arrangements.
    Problem There is thus a need for an arrangement which synchronizes the force generated by the hand of the normal user and the force required to energize the elastic member.
    Problem solving The presently proposed invention provides an arrangement which provides a solution to the stated problem with an arrangement of the embodiment stated in the introduction which is characterized in that the first distance is 1.2-1.6 times larger than the second distance.
    The invention is further characterized in that said distance is 1.3-1.5 times greater than the second distance.
    Furthermore, the invention is characterized in that said distance is 1.4 times greater than the second distance.
    In addition, the invention is characterized in that the angle between the distance lines before starting voltage setting is 58 ° -68 °.
    In addition, the present invention is characterized in that said angle is 61 ° -65 °. Finally, the present invention is characterized in that said angle is 63 '.
    BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described with reference to the accompanying fi gures in which: Fig. 1 is a diagram showing the relationship between the force increase in the elastic member and the deformation which occurs by the elastic member and the relationship between the force generated by a normal user how tightly he closes his hand; Fig. 2 is a view showing a stapler according to the present invention in which the side facing the viewer is made transparent. In the view, the elastic member is in an unstretched state; Fig. 3 is a view corresponding to Fig. 2 in which the elastic member is partially tensioned; Fig. 4 is a view corresponding to Fig. 2 in which the elastic member is fully tensioned; Fig. 5 is a detail view of the link arrangement included in the invention in which the arrangement is in the position shown in Fig. 2; Fig. 6 is a view corresponding to Fig. 5 in which the arrangement is in the position shown in Figure 3, and Fig. 7 is a view corresponding to Fig. 5 in which the arrangement is in the position shown in Fig. 4.
    Preferred Embodiment Figure 2 shows a stapler 1 which is equipped with the present invention. The figure does not show the side facing the viewer.
    As can be seen from the figure, the stapling apparatus comprises a frame 2. The frame has a magazine 3 in which staples 4 are stored in the form of a staple stack 5 which are intended to be driven in a workpiece 6. An elastic member 7 in the form of a leaf spring 8. Leaf spring is connected to a driver 9 which is slidably mounted in the body 2 in such a way that it can be moved up and down in the movement shown by the double arrow T. The bearing is not shown in the figures but it is obvious to the person skilled in the art why it not further described. The connection of the leaf spring to the driver takes place through a tongue 10 arranged on the leaf spring which engages in a first opening 11 arranged on the driver. To the frame is further arranged a link arrangement 12 which comprises a lever 13 which is rotatably arranged with a first coupling shaft 14 to the frame 2, the lever comprises a long arm 15 and a short arm loom, a link arm 17 which is rotatably mounted to the frame 2 with a second coupling shaft 18. and an intermediate joint 19 which is rotatably coupled to the short arm of the lever with a third coupling shaft 20 and rotatably coupled to the link arm 17 with a fourth coupling shaft. It further appears from the figure that the link arm 17 has an engaging member 22 which engages a second opening 23 in the driver 9. A plate 24 is further arranged to the body 2, against which the leaf spring 8 rests when the leaf spring is not energized by the link arrangement.
    With reference to Figures 2-4, the function of the invention will now be described in detail. In Figure 2, the stapler is in a starting position placed against a workpiece 6 in which a staple is to be driven.
    The driver 9 is in its initial position and the leaf spring 8 is untensioned.
    The leaf spring 8 is attached to the body with a screw 25, which is not clear from the figures, but the attachment is obvious to the person skilled in the art, so it is not further described herein. The long arm 15 extends from the body 2 and the link arm 17 is through its engaging member and the driver in force communication with the leaf spring 8. In figure 3 the long arm 15 has been rotated in the direction N down towards the body 2 and thus rotated about the first coupling shaft 14. moved the link arm 17 in the direction shown by the arrow R in the figure, which caused the engaging means 22 to lift the driver 9 upwards in the direction shown by the arrow U. This upward movement of the driver causes the leaf spring 9 to be tensioned. In Figure 4, the arm 15 has been lowered further towards the body and a further tensioning of the leaf spring has taken place. In the position shown in Figure 4, the driver is in the position from which it is released and by force of the leaf spring is moved downwards and hits the front clamp 4 in the staple stack 5. The release of the driver takes place by detaching the engaging member from the driver. This can be done in different ways, but since this function does not form part of the invention in question and since it can be done in several ways known to the person skilled in the art, it is not described further here. With reference to Figures 5-7, the link arrangement and its function will be described in detail. The figures show that the lever 13 is rotatably mounted about the first coupling shaft 14. The arm 13 is divided into a long arm 15 and a short arm 16. In the short arm 16 the joint 19 with a third coupling shaft 20 is mounted at a certain distance a from the first coupling shaft 14. The joint 19 is further connected by a fourth coupling shaft 21 to the link 17 at a certain distance b from the third coupling shaft 20. Between the first coupling shaft 14 and the third coupling shaft 20 a first distance line o1 extends and between the fourth coupling shaft 21 and the third The coupling shaft 20 extends a second distance line ß. These distance lines form an angle γ between them. When the link arrangement is in the position shown in Figures 2 and 5, the arrangement is in a starting position and the leaf spring is not energized. In this position there is no relation between the force generated in the leaf spring and the deformation to which the spring is subjected when it is tensioned because the leaf spring has not been tensioned. A point P 1 on the straight line shown in Figure 1 is therefore at the bottom left of the diagram. In Figures 3 and 6, the handle has been turned towards the body and the driver has been moved upwards, which means that the leaf spring is tensioned and the relationship between the force F and the deformation D of the leaf spring is such that a point showing this relationship in the diagram is at point P2. In Figures 4 and 7, the arm has continued to its final position and the relationship between the force F and the deformation of the leaf spring is then such that the point showing this relationship is in the position shown by P3 in the diagram.
    Since the force generated by a normal user when clenching his fist has such an appearance as shown by the curve H in the diagram in the figure, in order for the hand force to be best utilized, there is an exchange between the rotation of the arm 15 and the rotation of the link arm 17.
    By connecting the arm 13 to the link 17 with an intermediate joint and by dimensioning the distance a and b so that the first distance is 1.2-1.6 times larger than the second distance, an advantageous gear ratio is obtained. The exchange will be more advantageous if the said ratio is made 1.3-1.5 and it has been shown to be most advantageous to make the ratio 1.4.
    However, not only the relationship between the specified distances creates the optimal gear ratio but also the angle γ when the elastic member is not energized and the engaging means of the link arm 17 is in initial contact with the driver is of great importance. By keeping this angle 58 ° -68 °, an advantageous gear ratio is obtained. Even more advantageous is the gear ratio if the angle is kept 61 ° -65 ° and the most advantageous gear ratio if the angle is kept 63 ”.
    The invention is not limited by the above description but is limited only by the appended claims.
