1. A position-limiting device, comprising a base and a position-limiting member rotatably arranged on the base, wherein the position-limiting device further comprises a positioning member, the base has a hollow portion; the position-limiting member is switchable between a position-limiting state and a non-position-limiting state, in a case that the position-limiting member is in the position-limiting state, the positioning member fixes a position of the position-limiting member; and in a case that the position-limiting member is in the non-position-limiting state, the positioning member releases the position-limiting member, and at least a part of the position-limiting member is received in the hollow portion; and
wherein, the position-limiting member has a main body portion and a position-limiting portion, the main body portion comprises a first section and a second section, the first section has a first end rotatably arranged on the base and a second end connected to a first end of the second section, and a second end of the second section is connected to the position-limiting portion; and the second section and the position-limiting portion form a position-limiting area;
wherein, the positioning member comprises a first positioning member, a first end of the first positioning member is rotatably arranged on the base, and a second end of the first positioning member is a hook-shaped structure, the first section has a hollow portion, the hook-shaped structure is configured to pass through the hollow portion of the first section and hook a first side of the first section in the case that the position-limiting member is in the position-limiting state; and
wherein, the positioning member comprises a second positioning member, the second positioning member has a first end fixedly arranged on the base and a second end configured to abut against a second side of the first section in the case that the position-limiting member is in the position-limiting state; and the first side and the second side are two opposite sides of the first section.
