The structure of the present application enables the user to disassemble and assemble the nozzle by only unscrewing the cover body when in use, which is convenient to operate, easy to open and close, and more convenient for users to use, and the cover body is connected to the movable part in the base body so that the cover body will not fall off and cause loss.

[0036] Among them, a connecting hole 321 is provided at one end of the movable member 3 away from the locking hole 311, and the cover body 2 is provided with a connecting portion 21 corresponding to the connecting hole 321. The cover body 2 can be rotatably connected to the movable member 3 through the cooperation between the connecting portion 21 and the connecting hole 321. The connecting portion is arranged to cooperate with the connecting hole. When the cover body is rotated to open, the movable member moves horizontally in the base body, so that the locking hole corresponds to the through hole, so that the nozzle can pass through the locking hole and be assembled on the through hole.

[0037] The moving member 3 includes a sliding portion 31 and a hinged portion 32. The hinged portion 32 is arranged on the sliding portion 31. The sliding portion is arranged so that the sliding portion can be slidably connected in the baffle, and the hinged portion is arranged so that the cover body can be rotatably connected to the moving member.
