1. A clip device, comprising:
a clip and a storage tube, the clip including clip arms, the clip arms including a first clip arm and a second clip arm, a distal end of the first clip arm and a distal end of the second clip arm being for ligation;
the storage tube including an outer wall and a channel surrounded by the outer wall, a proximal end of the first clip arm and a proximal end of the second clip arm being stowable within the channel;
the clip further including a locked portion, the locked portion being connected with the clip arms: the storage tube further including a locking portion, the locking portion being restricted in movement relative to the outer wall toward the distal end of the first clip arm and the distal end of the second clip arm;
wherein in the locked state, the distal end of the first clip arm and the distal end of the second clip arm are closed and the locking portion cooperates with the locked portion to cause the storage tube to restrict a movement of the clip relative to the storage tube toward the distal end of the first clip arm and the distal end of the second clip arm; when a disassembly force is applied to the clamp device in a predetermined manner, a movement restriction of the clip by the storage tube is released and the clip is switched from the locked state to the unlocked state, the distal end of the first clip arm and the distal end of the second clip arm are able to be reopened, wherein the predetermined manner comprises:
applying the disassembly force to the locking portion to release the cooperation relationship between the locking portion and the locked portion; or
applying the disassembly force to the clip arms of the clip to release the connection relationship between the clip arms and the locked portion; or
applying the disassembly force to the storage tube to release the movement restriction of the locking portion relative to the outer wall.
