The compensation block 33 is fixed to the side of the positioning block 32 facing the auxiliary housing by bolts. At the same time, the bolt connection can be adjusted and replaced according to the actual size of the auxiliary housing to compensate for positioning errors and further improve positioning accuracy. The number of positioning parts 3 can be adjusted according to the external structure of the auxiliary housing and installed in conjunction with the mounting holes 101, making it highly adaptable.

[0057] Furthermore, such as Figure 1 , Figure 4-5 As shown, the support member 4 includes a positioning rod 41, a support rod 42, and an insert rod 43.

The insert rod 43 is located on the top of the positioning rod 41 and corresponds to the hole on the outer periphery of the auxiliary housing.

[0058] Specifically, the positioning rod 41 corresponds to the hole on the outer periphery of the auxiliary housing, and together with the insertion rod 43, it further improves the positioning accuracy and enhances the stability of the support 4; the support rod 42 abuts against the bottom of the outer periphery of the auxiliary housing, playing a role in stable support; the number of support 4 here can be adjusted according to the outer periphery structure of the auxiliary housing, and is installed in conjunction with the mounting hole 101, making it highly adaptable.
