[0005] The setting of the limiting structure is achieved by setting a limiting shaft, a rotating frame and an elastic member. The rotating frames located on both sides of the limiting shaft are limited by the elastic member to form a locking space in the space between the rotating frames. When the rotating arm rotates, it is against the rotating frame to complete the positioning. The operation of the locking device can be controlled by setting a lifting member. The rotating frame can be selected to limit the rotating arm or not. After the rotating arm is limited, when the rotating arm needs to be rotated to the storage position, the rotating frame can be lifted to the second position by the lifting member, so that the rotating arm and the rotating frame are staggered to complete the storage.

[0006] In one embodiment, the rotating frame includes a support plate, a connecting plate and a locking protrusion. There are two connecting plates, which are respectively arranged at both ends of the support plate. The connecting plate is provided with a through hole. One end of the connecting plate provided with the through hole is sleeved on the limit shaft, and the other end is connected to the support plate.

By providing one side of the arcuate surface and the other side of the horizontal surface at the end of the first arm protrusion, the arcuate surface can be used to press the rotating frame during rotation. Since the rotating frame is an arcuate surface, the rotating frame will overcome the elastic force of the elastic member to rotate, so that the first arm protrusion can rotate from one side of the rotating frame to the other side along the arcuate surface. After rotating to the other side, the horizontal surface faces the rotating frame, and the rotating frame cannot be rotated after the horizontal surface and the rotating frame are abutted.

[0013] In one embodiment, the first arm is further provided with a second arm protrusion, the length of the second arm protrusion is less than the length of the first arm protrusion; and further includes a bracket, the bracket includes a bracket body, a hinged portion and a rotating arm limiting protrusion, the hinged portion is arranged on the bracket body, the rotating arm is arranged on the hinged portion, the rotating arm limiting protrusion is arranged on the bracket body, and the rotating arm limiting protrusion is arranged corresponding to the second arm protrusion.
