Preferably, the other end of the guide rod is provided with a stopper to prevent the moving block from detaching from the guide rod under the elastic force of the return spring.

Preferably, a spring is arranged on the locking bar, so that the locking bar moves downward under the elastic force of the spring and keeps in contact with the raised end of the elastic sheet.

Preferably, the plug body is provided with L-shaped conductive sheets on the outer sides of the two metal inserts; one end of each conductive sheet is in contact with the metal insert, and the other end is provided with a through hole for connecting power cable.

Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

The quick plug-in plug of the present invention can put the insert piece into the power plug, and the power plug can be pulled out quickly with one hand, and the structure is simple, convenient and safe.
