The inclination direction of the first inclined driving structure 513 is opposite to the inclination direction of the second inclined driving structure 514. When the three-pin plug is inserted, the first inclined driving structure 513 drives the protective door slider 51 to compress the elastic member 52 and slide to the left to avoid the three-pin plug. In this embodiment, only one protective door slider 51 and one elastic member 52 are needed to realize the protection of one three-pin socket and one two-pin socket, and the structure is simple. Of course, as other embodiments, two or more protective door sliders 51 can also be provided.

[0056] Specifically, during the installation of the protection door assembly 5, first, the elastic member 52 is horizontally installed inside the bracket 53. Then, the protection door slider 51 is placed in the groove of the bracket 53. The first protrusion 512 on a set of side walls of the protection door slider 51 is installed in the guiding groove 532 on the side wall of the bracket 53. The sliding groove on the protection door slider 51 corresponds to the second boss 533. Finally, the assembled protection door assembly 5 is further assembled onto the gun head assembly 2. In particular, the limiting hole 501 at the edge of the bracket 53 of the protection door assembly 5 is aligned with the positioning post 2101 on the gun head housing 21 and sleeved and fixed. At this time, the vertical rod 531 on the bracket 53 is inserted into the cavity formed between the L-pole socket placement groove 221 and the N-pole socket placement groove 222, completing the installation and fixation of the protection door assembly 5 and the gun head assembly 2.
