[0009] Preferably, there are two limit springs, which are symmetrically arranged front to back about the column. The position of the connecting plate can be constrained by the limit springs to ensure the stability of the connecting plate in the locked state.

[0010] Preferably, the installation cavity is communicated with the interior of the groove, and the bayonet is slidably connected to the inner wall of the installation cavity. Under the action of the connecting plate and the limit spring, the bayonet can be inserted into the slot of the positioning block installed in the groove to lock the position of the positioning block.
