[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this solution, the operator inserts the charger plug into the groove of the rubber block. The tension causes the annular clamp to slide on the circumferential surface of the first bolt, clamping the electric vehicle charger plug. The second bolt limits the annular slider to prevent the entire device from shaking. The friction of the rubber block prevents the electric vehicle charger plug from falling off and provides protection. The operator starts the motor, and the slider, through the connecting rod, drives the clamped electric vehicle charger plug to slide on the circumferential surface of the threaded rod and the limiting rod, achieving automatic insertion and removal. The first and second limiting plates limit the slider to prevent wear and damage to the charger plug caused by excessive movement of the slider during sliding. This solves the problem that manual insertion and removal may cause wear and damage to the charger plug due to excessive force, thus affecting the quality and sales of the electric vehicle charger.

[0016] 2. In this solution, the electric vehicle charger is placed on the surface of the placement plate on the upper end of the fixed block by the personnel using this device. The second pneumatic rod drives the circular rubber block to push the electric vehicle charger against one side of the partition, which can fix the electric vehicle charger on the surface of the placement plate, thereby solving the problem of wear and tear caused by the charger falling due to improper operation by the personnel.

The stretching height causes the annular clamping block 7 to slide on the circumferential surface of the first bolt 6, clamping the electric vehicle charger plug. The second bolt 8 limits the annular slider 7 to prevent the entire device from shaking. The friction of the rubber block 9 prevents the electric vehicle charger plug from easily falling off and provides protection. The operator starts the motor 15, and the slider 11, through the connecting rod 10, drives the clamped electric vehicle charger plug to slide on the circumferential surface of the threaded rod 13 and the limiting rod 14, achieving automatic insertion and removal. The first limiting plate 12 and the second limiting plate 16 limit the slider 11 to prevent wear and damage to the charger plug caused by excessive movement of the slider 11 during sliding.
