A plurality of first clamps 7 are provided on the test plate 5, and second clamps 8 corresponding to the plurality of first clamps 7 are provided on the base 1. The first clamps 7 and the second clamps 8 respectively clamp the two ends of the rubber, so that a plurality of rubbers can be clamped and fixed at the same time. The reciprocating motion mechanism 4 drives the test plate 5 to perform reciprocating motion. When the test plate 5 performs reciprocating motion, it moves along the positioning rod 2. The positioning rod 2 can play a positioning and guiding role for the test plate 5, ensuring that the test plate 5 can only move in the vertical direction, thereby realizing repeated stretching operations on a plurality of rubbers and simultaneous testing operations on a plurality of rubbers, and achieving high rubber testing efficiency.

[0020] In some embodiments, the reciprocating motion mechanism 4 includes a shell 41 and a reciprocating frame 46. The shell 41 is fixedly connected to the bottom of the top plate 3.

The slider 49 and the limiting rod 48 can limit the reciprocating frame 46, ensuring that the reciprocating frame 46 can only reciprocate in the vertical direction.

[0022] In some embodiments, at least two groups of the first clamps 7 and the second clamps 8 are provided. By providing at least two groups of the first clamps 7 and the second clamps 8, each group of the first clamps 7 and the second clamps 8 can complete the clamping and fixing of one rubber, ensuring that at least two rubbers can be tested simultaneously.
