[0008] Preferably, a blocking part is arranged in the insertion hole, and an elastic member is arranged between the blocking part and the hinge shaft to provide the hinge shaft with an outward force.

[0009] By adopting the above-mentioned technical scheme, the elastic member can be arranged between the blocking part and the hinge shaft by arranging the blocking part, and the arrangement of the elastic member can realize the elastic and telescopic insertion of the hinge shaft into the insertion hole.

[0010] Preferably, the elastic member is a spring.

[0011] Adopting the technical scheme, the spring is a commonly used, very practical and mature elastic piece, and is suitable for use.

[0012] As a preferred, the hinge shaft is rotatably inserted into the insertion hole.

[0013] Adopting the technical scheme, the hinge shaft and the insertion hole cannot rotate with each other, the hinge shaft will rotate synchronously with the upper turning piece, excessive friction and wear can be avoided, and the problem of abnormal sound caused by touching the elastic piece under mutual rotation can also be avoided.

[0014] As a preferred, the side wall of the insertion hole is provided with a rotation stopping structure; the hinge shaft is correspondingly provided with a limiting structure; the rotation stopping structure and the limiting structure cooperate to prevent the hinge shaft from rotating relative to the insertion hole.

[0015] Adopting the technical scheme, the hinge shaft is rotatably inserted into the insertion hole through the cooperation of the rotation stopping structure and the limiting structure.

[0016] As a preferred, the rotation stopping structure is a slot provided on the side wall of the insertion hole; the limiting structure is a protruding rib provided on the side wall of the hinge shaft; the protruding rib is inserted into the slot.

[0017] Adopting the technical scheme, the rotation stopping structure is a slot provided on the side wall of the insertion hole; the limiting structure is a protruding rib provided on the side wall of the hinge shaft; the protruding rib is inserted into the slot. BRIEF DESCRIPTION OF DRAWINGS
