[0026] By adopting the above technical solution, the guide block 61 on the joint 3 is aligned with the guide groove at the bottom of the shell 2 and inserted, which facilitates the plugging of the connecting rod 65 and the connecting groove 62, making the device assembly more convenient.

[0027] Specifically, the auxiliary component 63 includes a rotating block 631, a slot 632, a transmission plate 633, a screw 634, an insertion rod 635 and an insertion block 636.
