A support spring 6 is arranged on the left side of the lower surface of the positioning bar 5. The support spring 6 is connected to the mounting plate 1. The elastic force of the support spring 6 can drive the left side of the positioning bar 5 to rise, thereby driving the right side of the positioning plate 9 to move downward through the hinge shaft 4 to clamp the test plate 2.

A limit block is set on the right side of the lower surface of the positioning strip 5, and an oblique structure is set on the right side of the lower end of the limit block, and two groups of positioning grooves matching the limit block are relatively set on the left and right sides of the test board 2. The limit block can limit the movement range of the test board 2 to prevent the test board 2 from being displaced or loosened during the installation process, thereby improving the stability of the overall structure, and the oblique structure of the limit block can facilitate the limit block to be inserted into the slot opened on the test board 2.

The multiple sets of wire fixing components also include positioning springs 8. Two sets of positioning springs 8 are arranged on the upper and lower sides of the wire fixing frame 7, and a positioning plate 9 is provided on the side where the two sets of positioning springs 8 are close to each other.
