Wherein, the third locking member 501 is disposed at one side of the connecting body 500 and is disposed close to the cover 300; the fourth locking member 502 is disposed on one side of the connector 500 and on the same side of the third locking member 501, and is disposed close to the tube 400; when the cap 300 and the tube 400 are connected to each other in an insertion manner, the connector 500 is bent, the third locking member 501 moves upward along with the bending of the connector 500, and is positioned directly above the fourth locking member 502, and the third locking member 501 and the fourth locking member 502 are locked to each other, thereby locking the position of the connector 500.
The third locking member 501 is a card slot, the fourth locking member 502 is a card block, and the third locking member 501 and the fourth locking member 502 are engaged with each other.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
