When a pair of racks 202 move relatively, the threaded rod 107 cannot rotate easily due to the arrangement of the torsion spring member, that is, the gear member 108 cannot rotate easily, that is, when the racks 202 move and the torsion force of the torsion spring member is greater than the moving driving force, the gear member 108 meshed with the rack members does not rotate, but the racks 202 directly drive the gear member 108 to move horizontally, that is, the translation plate 104 can be driven to move, so that the compression block 101 moves to the upper side of the extension block 301, and the guide block 105 contacts with the fixed table 401, the translation plate 104 cannot move any more, the racks 202 keep moving until the driving force is greater than the torsion force of the torsion spring member, the racks 202 drive the gear member 108 to rotate, drive the threaded rod 107 to descend, thereby compressing the compression block 101 on the shock pad body, and then when the compression block 101 needs to be driven to move reversely for tensile test, because the shock pad body is tightly pressed by the pressing block 101, the screw thread connection between the threaded rod 107 and the screw thread sleeve 106 has self-locking property, when the rack 202 moves reversely, the gear piece 108 cannot be easily rotated due to the self-locking property of the threaded rod 107, namely, the rack 202 directly pushes the gear piece 108 to move, the translation plate 104 can be driven to move, so that the shock pad body is subjected to tensile test until the translation plate 104 moves to the starting point, the shock pad body cannot move, the rack 202 at the moment keeps moving until the driving force is greater than the locking force between the threaded rod 107 and the screw thread sleeve 106, the rack 202 drives the gear piece 108 to rotate, thereby driving the pressing block 101 to rise and reset, the shock pad body detection work can be completed, the process synchronism is good, the shock pad body can be directly lifted after the movement of the pressing block 101 is in place, no additional controller is needed for control, the working efficiency is improved, the threaded rod 107 is not required to be driven by an additional driving assembly, and the lifting and descending of the pressing block 101 and the reciprocating linear motion of the translation plate 104 can be realized only through the movement of the rack 202, so that the practicability is high, the cost is saved, and the degree of automation is high.

In the above embodiment, since the rack 202 needs to push the gear member 108 to move and needs to keep the gear member 108 not to perform a rotation motion, however, when the compression block 101 performs a tensile test on the shock pad body, the acting force applied to the compression block 101 at this time increases along with the elongation of the shock pad body, which easily causes the rack 202 to drive the gear member 108 to rotate, and causes the compression block 101 to lift and reset, so that the detected data is inaccurate, in order to further ensure the detection stability of the compression block 101, a limiting frame 109 is provided, specifically, two sides of the top plate 102 are provided with stop blocks 111, the stop blocks 111 are clamped in the notch-shaped grooves 110 and are in sliding fit with the notch-shaped grooves 110, the stop blocks 111 and the top plate 102 can be limited, specifically, when the rack 202 drives the gear member 108 to move, due to the arrangement of the torsion spring members, the rack 202 initially drives the gear member 108 to move horizontally, the top plate 102 and the stop block 111 move along, the stop block 111 enters the upper lateral part of the square groove 110, so that the heights of the stop block 111 and the top plate 102 are limited, the stop block can only move laterally, and cannot move up and down, namely, the stability of the rack 202 when driving the gear piece 108 to move horizontally can be ensured, the gear piece 108 cannot be driven to rotate until the stop block 111 moves to the right angle of the square groove 110, the pressing block 101 descends to press down the shock pad body, then, due to self-locking property, the rack 202 can initially push the gear piece 108, the stop block 111 enters the lower lateral part of the square groove 110, the height position is limited again, the pressing block 101 can be always pressed on the shock pad body to stretch, the rack 202 cannot drive the gear piece 108 to rotate, namely, the square groove 110 and the stop block 111 are arranged, therefore, the movement of the top plate 102 is limited, so that the top plate 102 can only move according to the process flow, and the stability of the compression block 101 in tensile test is further ensured.
