The rotatable ring 14 is externally fixedly connected to the rotatable screw 12, which can make the rotatable screw 12 rotate inside the mounting base plate 11 and drive the mounting base plate 11 to move synchronously. The rotatable ring 14 is externally rotatably connected to the interior of the mounting base plate 11.

[0020] A sealing gasket 15 is provided between the upper surface of the first mounting plate 8 and the lower surface of the second mounting plate 9, and the sealing gasket 15 seals the connection between the first mounting plate 8 and the second mounting plate 9.
