[0031] Reference Figure 1 : Connection sleeve 21 is hexahedron. In the embodiment, the shape of connection sleeve 21 is further limited.

[0032] Reference Figure 2 ​The opposite side of the positioning part 222 is connected with a spherical sliding block 23, and the sliding block 23 is detachably connected with the positioning part 222 through a screw. In the embodiment, the sliding block 23 is used for sliding relative to the welding part, the sliding block 23 is spherical, and point contact is formed between the sliding block 23 and the welding part, so that the friction between the sliding block 23 and the welding part can be effectively reduced.
