[0061] Optionally, the elastic part 24 is connected with the first positioning pin 23 and the support plate 10 respectively, so as to provide elastic force for the first positioning pin 23.

[0062] Optionally, a plurality of rotating rods 25 are uniformly distributed around the circumference of the first adjusting rod 22, so that the rotating rods 25 can be used to set an acting force on the first adjusting rod 22, and then the relative position between the first pressing block 21 and the first adjusting rod 22 can be adjusted.

[0063] Similarly, the second positioning assembly 30 comprises a second pressing block 31, a second adjusting rod 32, a second positioning pin 33 and a locking part 34, the clamping cooperation of the second adjusting rod 32 and the second positioning pin 33 realizes the clamping of the chain track link 40 to be detected, and the locking part 34 is screwed with the second adjusting rod 32 and abuts against the second pressing block 31 to lock the position of the second adjusting rod 32.

[0095] The second pressing block 31 is arranged in the first direction and spaced apart from the first pressing block 21, and is detachably connected with the support plate 10.

[0096] The second adjusting rod 32 penetrates through the second pressing block 31 and is in abutment with the chain link 40 to be detected in a direction perpendicular to the support plate 10.

[0097] The second positioning pin 33 is arranged on the surface of the support plate 10 and is in abutment with the side of the chain link 40 to be detected away from the second pressing block 31.

[0098] Specifically, the present embodiment provides an implementation of the second positioning assembly 30, the arrangement of the second pressing block 31 provides a mounting position for the second adjusting rod 32, so that the second adjusting rod 32 can apply force from above the chain link 40 to be detected, and then clamp the chain link 40 to be detected, and the second positioning pin 33 is arranged on the support plate 10, for clamping the chain link 40 to be detected from two directions together with the second adjusting rod 32.

[0106] Specifically, the present embodiment provides an implementation manner of the first adjusting rod 22 and the second adjusting rod 32, which are arranged to have a certain height difference, for cooperating with the shape of the chain track link 40 to be tested, and ensuring the clamping of the chain track link 40 to be tested to be more stable.

[0107] In possible implementation manners, the first positioning pin 23 and the second positioning pin 33 also have a corresponding height difference, for ensuring the clamping of the chain track link 40 to be tested after assembly to be more stable and firm.

[0108] In some possible embodiments of the present application, the second positioning assembly 30 further comprises a locking part 34, which is threadedly connected with the second adjusting rod 32 and abuts against the second pressing block 31, for locking the second adjusting rod 32.
