When the movable slide rail 1 and the fixed slide rail 2 are in the closed state, the movable slide rail 1 is suddenly and violently pulled out. At this time, the hook slider 40 will be subjected to a large downward pressure impact force, which may easily cause the hook slider 40 or the dial needle 10 to break. At this time, the stress point of the hook slider 40 is at the impact force block 402, and the impact force is The block 402 will exert an impact force on the groove plate of 31. In order to prevent the hook slider 40 or the dial needle 10 from breaking, the groove plate here is set as a compressible and deformable elastic groove edge 32. When the impact force block 402 is at this position When subjected to an impact force, the impact force block 402 will press down on the elastic groove edge 32, the elastic groove edge 32 is deformed, and the impact force block 402 is directly tripped from the pendulum needle chute 311, then the hook slider 40 will rotate as a whole , the hook slider 40 will no longer block the pulling needle 10 from pulling out, and the hook slider 40 will not be broken due to excessive impact and cannot rotate. When the impact force block 402 needs to be reset, the setting needle 10 will be pushed toward the setting needle again. Block 43, when the rebound slider 4 drives 40 to move backward, the impact force block 402 is pulled back and bounces back into the swing needle chute 311, and the rebound slider 4 returns to the normal state. Therefore, the present invention not only can The automatic opening and damping closing functions of the movable slide rail 1 and the fixed slide rail 2 are realized, and when the movable slide rail 1 and the fixed slide rail 2 are forcibly pulled, the hook slider 40 can be rotated and disengaged from the hook block chute 310 through the elastic component. so that the packing needle 10 and the hook slider 40 can be released smoothly without causing excessive impact force on the parts of the adjustment needle 10 and the hook slider 40, preventing the breakage and damage of the connecting parts, and greatly improving the main body 3 of the rebounder.
