the buffer spring 42 is sleeved at two ends of the sliding rod 43;
the bearing 41 is used for carrying the sliding rod 43, and the sliding rod 43 can axially slide on the bearing 41.
When the pendulum 2 is knocked to one end of the sliding rod 43, under the action of impact force, the test platform 44 moves backward instantaneously, so as to achieve the effect of the recoil of the gun, and the impact of the recoil on tactical accessories mounted on the sliding rail 45 is detected.
