a top cap, arranged above the bottom cap, and hinged with the first top rod;

a locking mechanism, arranged between the top cap and the central rod, and provided with a locked state and an unlocked state; and

an operation part for a user to operate to lock and/or unlock the locking mechanism, the operation part located at the bottom of the central lock;

wherein the locking mechanism comprises a first locking member arranged on the central rod and a second locking member arranged on the top cap that is matched with the first locking member;

wherein, when the locking mechanism is in the locked state, a relative position between the top cap and the central rod is fixed, and a relative position of the first locking member and the second locking member is fixed;

wherein, when the locking mechanism is in the unlocked state, the relative position between the top cap and the central rod can be released, and the relative position of the first locking member and the second locking member can be released;

wherein the central rod and the bottom cap are rotatably connected, the first locking member is a protruding portion fixedly arranged on the central rod, and the second locking member comprises a helical groove arranged on the top cap and a limiting groove connected with a terminal end of the helical groove;

the bottom cap and the central rod are configured with an elastic element therebetween; under the action of external force, the protruding portion can move from an initiating end to the terminal end of the helical groove and abut into the limiting groove; under the action of external force, the elastic piece can exert force on the central rod so that the protruding portion has a tendency to disengage from the limiting groove and move from the terminal end to the initiating end of the helical groove.
