In this way, the compression spring 205 always in the half-compression state can always provide the elastic force in the horizontal direction for the driving handle 201, so that the auxiliary door body 200 can be stably locked on the main door body 100, and when a user needs to open the auxiliary door body 200, only the driving handle 201 needs to be pressed to compress the compression spring 205 again, at this time, the driving handle 201 moves towards the handle 202, so that the second arm 602 moves downwards, and the hinge shaft 500 and the movable shaft sleeve 400 are unlocked, the two can rotate relatively, the auxiliary door body 200 can be opened in a rotating manner, the compression spring 205 can not obstruct the opening of the auxiliary door body 200, the locking stability of the auxiliary door body 200 is guaranteed, and the sealing performance of the auxiliary door body 200 is improved.

It will be appreciated that: the half-compressed state of the compression spring 205 refers to the compression of the compression spring 205 from the natural extended state to half of the maximum compression state travel.

Noteworthy are: when the auxiliary door body 200 is closed, the user presses the driving handle 201 to enable the compression spring 205 to be always in the maximum compression state, and after the auxiliary door body 200 is determined to be completely closed, the driving handle 201 is released, and at the moment, the driving handle 201 can be rapidly pushed to drive the support arm 600 to move upwards by utilizing the elasticity of the compression spring 205, so that the limit protrusion 501 can be smoothly flushed into the limit groove 402, and the auxiliary door body 200 can be smoothly locked.

As shown in fig. 9, in some embodiments, the lower side wall of the main door body 100 is provided with a hinge plate 700, the lower side wall of the sub door body 200 is provided with a shaft hole, the upper side wall of the hinge plate 700 is provided with a support shaft 701, and the support shaft 701 is inserted into the shaft hole and is rotatable relative to the shaft hole. In this way, the support shaft 701 of the hinge plate 700 connected to the main door body 100 is rotatably inserted into the shaft hole of the sub door body 200, so that the bottom of the sub door body 200 can be supported and fixed by the hinge plate 700 and the support shaft 701 thereon, and the movement of the bottom of the sub door body 200 is restricted, thereby avoiding the situation that the bottom of the sub door body 200 is shifted or rocked during the opening and closing of the sub door body 200, and improving the stability of the opening and closing of the sub door body 200.

Alternatively, the supporting shaft 701 is positioned on the same vertical line as the axis of the hinge shaft 500. In this way, the relative position between the support shaft 701 and the hinge shaft 500 is set more reasonably, which is helpful to reduce the influence of the support shaft 701 on the opening of the auxiliary door body 200, avoid the support shaft 701 blocking the opening of the auxiliary door body 200, and ensure the smoothness and stability of the process of opening the auxiliary door body 200.
