The two groups of pawls 16 are respectively arranged corresponding to the two groups of ratchets 14. The two groups of pawls 16 are meshed with the corresponding ratchets 14. A torsion spring 17 is sleeved on both groups of rotating rods 15, and the torsion spring 17 is fixedly connected to the corresponding rotating rod 15 and the protective shell 1 respectively.

[0023] The protective shell 1 is provided in conjunction with a plurality of groups of protective plates 5 distributed in an annular manner on the protective shell 1 to achieve closed protection for the wrapped head, thereby reducing the contact between the two poles of the plug 3 and the external air, thereby reducing the risk of contamination with a large amount of dust or moisture, causing oxidation of the two poles of the plug 3, affecting the resistance of the plug 3, and resulting in a decrease in safety performance.

[0024] like Figure 2 and Figure 3 As shown, the two groups of mobile frames 6 are both slidingly connected to the mounting frame 2, and two groups of symmetrically distributed first bidirectional screws 18 are provided in the mounting frame 2.

[0026] The utility model provides a plug with good protective performance. The specific working principle is as follows: when the plug 3 is in use, the screw rod 4 is manually rotated to move the plug 3 to the right end of the protective shell 1 and normally connected to the socket for use. When the plug 3 is not in use, the screw rod 4 is manually rotated to retract the plug 3 into the protective shell 1, and the two sets of rotating rods 15 are moved to make the two sets of pawls 16 respectively release the restriction effect on the ratchet 14, and the mounting shaft 13 and the driving wheel 12 on the mounting shaft 13 can rotate normally.

The cleaning rollers 24 effectively clean the dust or other impurities adhering to the two poles of the plug 3, and the impurities adhering to the cleaning rollers 24 are cleaned during the friction between the cleaning rollers 24 and the scraper 23.
