[0024] Positioning plate 3 and pipe head 5 slidingly connect, and pipe head 5 and gasket 4 are attached, facilitating pipe head 5 to move and disassemble, and the sealing of pipe head 5 is improved through gasket 4.

[0025] Limit base 6 and positioning column 8 form a sliding structure, the normal section shape of limit base 6 is arranged as a T-shaped shape, and limit base 6 and baffle ring 9 are attached, facilitating pipe head 5 to disassemble, pipe head 5 to drive positioning column 8 to separate from limit base 6, and limit base 6 to be limited through baffle ring 9 attached to limit base 6, thereby ensuring the firmness of the whole device.

[0026] Limit base 6 is distributed at equal angles on positioning plate 3, and limit base 6 and positioning column 8 are distributed one by one, facilitating stable connection of positioning plate 3 and pipe head 5.

[0027] Positioning column 8 and limit cap 10 are screw set, and limit cap 10 and limit base 6 are attached, facilitating users to set limit cap 10 on positioning column 8 and tighten limit cap 10, so that limit cap 10 is attached to limit base 6, thereby clamping and limiting limit base 6 through limit cap 10 and baffle ring 9.

[0028] The locking mechanism 11 includes a locking plate 1101 and a knob 1102. The locking plate 1101 is fixedly installed on the end face of the limit cap 10, and the knob 1102 is movably connected to the inner wall of the locking plate 1101, so as to limit the limit cap 10 through the locking mechanism 11, thereby preventing the limit cap 10 from loosening.
