The upper end of the top seat 3 is fixedly provided with a lifter 6, and the interior of the top seat 3 is provided with a cavity 7. The output end of the lifter 6 is provided with a shear force test sensor 8 located inside the cavity 7. , a shearing knife 9 is provided at the test end of the shear force test sensor 8, a motor 11 is fixedly arranged on both sides of the base 2, a bending rod 10 is provided at the output end of the motor 11, and a limit block for limiting the top seat 3 is provided at the top end of the bending rod 10, and two straightening assemblies are symmetrically arranged at the upper end of the test bench 1, and the straightening assemblies include a first propeller 12 and a U-shaped rod 13, and the U-shaped rod 13 is fixed at the output end of the first propeller 12, and second propellers 14 are fixedly arranged at both ends of the U-shaped rod 13, and a clamping block 15 is fixedly arranged at the output end of the second propeller 14;

[0022] In this structure, the top seat 3 is fixed on the base 2, the stainless steel wire is passed through the first groove 4 and the second groove 5, and the second propeller 14 is started, so that the multiple clamping blocks 15 can clamp and fix the two ends of the stainless steel wire, and then the two first propellers 12 are started, so that the U-shaped rod 13 can drive the two second propellers 14 to move, so that the stainless steel wire can be straightened to avoid bending of the stainless steel wire in the first groove 4 and the second groove 5, and the accuracy of the stainless steel wire in the shear test can be improved;

[0023] Starting the lifter 6 can make the shear force test sensor 8 drive the shear knife 9 to descend, so that the shear knife 9 can shear the stainless steel wire. In this process, the shear force of the shear knife 9 can be detected by the shear force test sensor 8.
