    Brief Description of the Drawings The invention will now be described in more detail in connection with a preferred embodiment of the invention with reference to the accompanying drawing, in which Figure 1 is a schematic perspective view of an embodiment of the locking mechanism according to the invention, Figure 2 is a schematic side view of the mechanism shown in Figure 1, and Figure 3 is a schematic side view of a hand tool comprising the locking mechanism according to the invention.
    Detailed description of the invention The locking mechanism according to the invention is designed to be used with hand tools Y9, such as pliers of various kinds, and in particular with crimping tools, having two handles which are pivotally connected to each other.
    Figure 1 and Figure 2 illustrate the locking mechanism according to the invention as a first and second handle element part 1 and 2 respectively. The handle element parts are connected to each other by a pivot pin 3. Depending on the tool, the handles extend with different shapes on the "other side" of the pivot connection. A hand-held crimping tool is illustrated in Figure 3 as an example, but the concept of the invention is not limited to crimping tools.
    The locking mechanism according to the invention thus comprises said two handle element parts 1 and 2 and a locking arrangement which acts between said element parts.
    Arranged on the first handle element part 1 is a first arm 4 which carries a row of teeth 5, which extends over part of said arm, leaving an empty space between said first handle element part 1 and said row of teeth. Arranged on the second handle element part 2 is a pawl 6 mounted on or constituting an integral part of a second arm 7.
    Consequently, the pawl and the other arm are in fact one and the same element, which is an important improvement over prior art devices.
    The first arm 4, which supports the row of teeth, is preferably curved corresponding to the pivoting movements of the handle element parts around the pivot pin 3.
    In a preferred embodiment, shown in Figures 1 and 2, the row of teeth protrudes laterally (at 12) beyond the first arm and has a smooth surface 5 'on the opposite side from the teeth 5.
    At the end of the first arm 4 a first guide surface 8 is arranged, which slopes upwards towards the row of teeth. The end of the second arm 7 is formed with a corresponding second guide surface 9 which is directed upwards.
    Said arms are arranged on said handle element parts with their longitudinal axes parallel to each other and displaced so that when said handle element parts are pressed together they will move next to each other. The pawl projects laterally from the flexible arm so that it will slide on the row of teeth and when the handle member parts are pressed together the pawl will jump over the teeth in row one and one and when the compressive force is released the pawl will be caught on one of the teeth. At least one of said first and second arms 4, 7 is flexible.
    In a preferred embodiment, which is illustrated in the drawing, the second arm comprising the pawl 6 is flexible. However, in the mechanism of the invention, the arm carrying the row of teeth may be the flexible arm, or both arms may be flexible. When the flexible arm is bent and the pawl is guided on the row of teeth, it exerts an elastic force and the pawl will be pressed against the teeth with a sufficient pressure to keep the pawl in contact with the row of teeth.
    At the inner end of said row of teeth a third guide surface 10 is arranged. When the pawl has passed the last tooth in the row of teeth, the elastic force will cause the pawl to move along said third guide surface, and the handle member parts will again be free to move away from each other. During this return movement, the pawl will move freely along the smooth surface. This can be done without any tension from the flexible arm or the flexible arm can exert a small force against said smooth surface, so that its guide surface overlaps with the above-mentioned second guide surface on the end of the rigid arm.
    Preferably, a groove 11 is provided in the second handle member portion 2, in which groove the protruding portion 12 of the row of teeth can move freely when the handle member portions are compressed and then returned.
    In the embodiment illustrated in the drawings, the row of teeth is arranged on the inside of the rigid arm 4, i.e. on the side facing the rotary connection between the handle element parts 1 and 2. However, it would also be possible to arrange the row of teeth on the outside of the rigid arm with a corresponding adjustment of the guide surfaces for guiding the pawl downwards on the row of teeth and then upwards on the smooth surface on the opposite side relative to the row of teeth.
    Referring to Figures 1 and 3, the laterally projecting tab 13 is provided on the flexible arm. By means of this tab 13, the pawl can be manually released from the row of teeth 10 anywhere during, for example, a crimping process. The tab 13 may be arranged next to the pawl or otherwise spaced from the pawl on the flexible arm, as illustrated in Figure 3.
    Figure 3 illustrates the locking mechanism in connection with a crimping tool 14. A coil spring 15 is arranged between the first and second handle element parts 1, 2. When the pawl 6 has passed the last tooth in the row of teeth and the grip on the handles is released, the coil spring will push the first and the second handle member portions away from each other, the pawl will slide along the third guide surface and the tool will return to the home position.
