The outer diameter of the closed end of the spring housing is larger than the inner diameter of the passage hole of the door handle. In other embodiments, when the closed end of the spring housing is moved into abutment with the door handle, the closed end of the spring housing may restrict the door latch from continuing to move in a direction away from the electric actuator; the thrust to the door pin, which is generated when the rotating shaft of the electric actuator rotates, can make the door cover rotate towards the direction close to the base.

A spring 28 is arranged in the spring sleeve 27, the door pin 24 is sleeved with the spring 28, one end of the spring abuts against the closed end of the spring sleeve, and the other end of the spring abuts against the inner wall of the door handle.

When the door cover is opened from a closed state, the elastic force of the spring is applied to the door pin, and the door pin can be assisted to move towards the direction away from the locking seat, so that the door cover is opened more easily.

As shown in fig. 5, a cylinder 30 for pushing the base to rotate is further connected to the base 11, and a piston head of the cylinder 30 is hinged to the base 11.
