Part of the limiting member 3 is located in the mounting outer notch 22. The outer end of the limiting piece 3 is provided with a poking part 31, and the poking part 31 extends out of the mounting outer notch 22. Therefore, the stirring of the limiting piece 3 is facilitated, and the movement of the limiting piece 3 between the first position a and the second position b can be realized by stirring the stirring part 31. The inner end of the stopper 3 is configured as a first mounting portion. When the limiting piece 3 is at the first position a, the first installation part is positioned in the installation inner notch 23; when the outer end of the limiting piece 3 is shifted, the first installation part can drive the second installation part to move; the second mounting portion may be offset from the mounting inner notch 23 when the stop 3 is moved from the first position a to the second position b.

When the functional accessory 4 is installed, the outer end of the limiting piece 3 is shifted to enable the limiting piece 3 to be located at the first position a, the second installation portion on the functional accessory 4 is matched with the first installation portion, then the outer end of the limiting piece 3 is shifted to enable the limiting piece 3 to move to the second position b, in the process that the limiting piece 3 moves to the second position b, the first installation portion drives the second installation portion to deviate from the installation inner notch 23, at the moment, the displacement of the second installation portion can be limited, the displacement of the functional accessory 4 can be limited, and the installation of the functional accessory 4 is completed.
