Referring to fig. 12, in a possible implementation manner of the present application, the transmission member 222 is provided with a positioning post 2224 corresponding to a first end of the elastic member 223, the base body 21 is provided with a positioning hole 215 corresponding to a second end of the elastic member 223, the first end of the elastic member 223 is sleeved on the positioning post 2224, and the second end of the elastic member 223 extends into the positioning hole 215, so as to limit the elastic member 223 between the transmission member 222 and the base body 21.

In order to ensure that the limiting member 221 moves along the first direction without shaking, referring to fig. 2 and 3, in one possible implementation manner of the present application, a mounting hole 216 is provided on the base body 21, an axis of the mounting hole 216 is disposed perpendicular to the second direction, a radial profile of the limiting member 221 is similar to a radial profile of the mounting hole 216, and the limiting member 221 is slidably connected in the mounting hole 216 and is configured to abut against the plug body 31 to limit the plug body 31 along the second direction when the limiting member 221 extends out of an end of the mounting hole 216.

In order to facilitate the installation of the plug 3, referring to fig. 10 and 11, in one possible implementation manner of the present application, an abutting inclined surface 2212 is provided on the limiting member 221, and the abutting inclined surface 2212 is used for being abutted by the plug body 31, so that the limiting member 221 is retracted into the base body 21. Specifically, the abutting inclined surface 2212 is disposed on one side of the limiting member 221 away from the non-open end of the mounting slot 212, and along the extending direction of the limiting member 221, the distance between the abutting inclined surface 2212 on the limiting member 221 and the opposite surface thereof gradually decreases.

The above-mentioned serial numbers of the embodiments of the present application are merely for description and do not represent the merits of the embodiments. The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all the equivalent structures or equivalent processes that can be directly or indirectly applied to other related technical fields by using the contents of the specification and the drawings of the present application are also included in the scope of the present application.
