It is provided at the rear with a lock-side (tip-side) end on an annular stop 110, which is supported as a rear front collar 9 c of the firing pin 9. Serves support for the fork 13, in front of which the extension 11 of the firing pin 9 has a disc 116 which, with the return spring 15, has an annular groove 11 α, in a V-shape, in which (according to FIG. 1, cooperates.

These locking pins have one of the firing pin forms. The permanent magnet 111 obtuse-angled tip. The locking pins are seated an annular groove 111 α in V-shape and can be diametrically opposite and a return spring 19 holds them recess 112 of the block 105, which is on the housing 1 outside the annular groove 11 α (according to FIG. 3). Furthermore, 15 is fixedly mounted, slide.

The firing pin device works as follows: To guide the pin 109 and to achieve it If you pull the trigger 3 without locking its coaxiality with the permanent magnet 111 is used To press pins 18, the fork 13, which has a guide sleeve 20, which consists of a non-magnetic firing pin 9 with the firing pin spring 17, which consists of metal that is verrineiform with the bolt 109 Stop 10 and the disc 16 is freely bound after 25 and can slide into an annular gap that move forward, with only the return spring 15 compressed between the cylindrical surface of the permanent is, while the firing pin magnets 111 and the wall of the cylindrical boh spring 17 stays relaxed. A triggering of the tion 112 is.

Bolt 9 is blocked, causes the actuation of the If you press the buttons 118 α , there is first a forward movement of the 4 ° to trigger 3, next a blocking of the permanent magnet 111 and disk 16 and a compression of the back of the bolt 109. If you then the Trigger 3 and adjusting spring 15 and the firing pin spring 17 (Fig. 4). the fork 13 is actuated, the firing pin spring 17 is at the end of the tensioning process (caused by tensioned. The sudden loosening of the pin tip 9 a the contact of the fork 13 with the stops 9 x), the permanent magnet 111 can either overcome the impact on the firing pin 9 due to the pressure exerted by the trigger 3 after having covered a certain distance, the blocking effect of the locking pins 18 due to the application of the fork 13 against the stops, because the holding hand is exposed to 109 χ (Fig. 8) and this or force applied is exceeded. The locking pins 18 are made under the action of the spring 17, depending on the preload of the firing pin. The permanent magnet remains in the inclined surface of the V-shaped annular groove 11 α at its 5 ° position, in which it is held by the locking pins 118. In the case of blunt tips out of the annular groove 11 α , in this embodiment it is not necessary that pressure is applied. Thus released, the firing pin 9, the annular groove 111 «is V-shaped, it can suddenly have a rectangular shape due to the relaxing impact. The ends of the locking pin spring 17 driven forward and the striker pins 118 also do not need to have a conical pin tip 9 α hits the cartridge through the hole 8, they can also be cylindrical, ink (Fig. 5). . ..
