Specifically: under unfired state, the platform of the shearing piece and body 6 of the shearing position limiting slide block 8 in the percussion lock
The step of rank type counterbore contradicts, and under the barrier effect of shearing piece, shears position limiting slide block 8 without normal direction body center movement, therefore
Being relatively large in diameter end and can not contacting with conductive sheet for power supply sliding block 12, so that interlocking assembly be made to be in an off state, ensure that individual soldier
The thruseer and aircraft engines of rocket projectile will not light a fire in this case.
When man-portable rocket leads to the shearing piece fracture for shearing position limiting slide block 8 because the perturbed forces effect such as impacting, colliding, cut
Position limiting slide block 8 is cut to body center movement, but when the perturbed force due to the generations such as impacting, colliding and normal percussion firing pin percussion
Power has a different characteristics in amplitude and pulsewidth, therefore percussion force threshold response sliding block 9 and spring 10 will not be to interfering at this time
