The charging gun is an important device used to connect the charging pile and electric vehicles for charging. With the continuous expansion of the new energy vehicle market, the demand for charging piles is also growing.

[0003] When charging an electric car, you need to remove the charging gun from the charging pile, then take the charging gun to the charging port of the electric car, and insert the charging gun into the charging port for charging. Since the charging gun has a large gravity and there is a cable at the tail, the charging gun is easy to fall when it is moved, causing damage to the charging gun. Therefore, in order to prevent the charging gun from falling and being damaged, common charging guns are provided with a protective casing to protect the charging gun.

[0004] However, in order to increase the protection effect, the common anti-drop plastic shell of the charging gun is usually larger in size. When the gun is pulled out, the charging gun is easily stuck. After the size of the charging gun increases, it is not easy to hold, making it more difficult to pull out the gun. In view of this, the present application proposes a plastic shell of a charging gun that is anti-drop for a charging pile. Utility Model Content

[0015] The anti-dropping and damage-proof charging gun plastic shell for the charging pile has an auxiliary gun-pulling assembly arranged between the main body protection rings. When the charging plug is stuck in the column, the driver can use a flat-head screwdriver to turn the flat nut to drive the control screw to rotate. The control screw moves toward the charging plug under the action of the fixing nut, drives the top plate to support the shell at the charging port of the car, and pushes the charging plug outward to loosen the charging plug. This solves the problem that the charging gun is easy to get stuck when pulling out the gun, and the charging gun is difficult to hold after the size of the charging gun increases, making it more difficult to pull out the gun.
