The insertion rod forms a hinged rod, so that the support member rotates around the insertion rod, one end of the support member moves downward, and the other end with the clamping block rotates downward. When rotating downward, the clamping block presses the spring sheet downward to compress the spring. At this time, the card can be removed. After the card is removed, the lifting valve can be disassembled and assembled.

[0007] As a further configuration of the utility model, the pressing block comprises a C-shaped block, the notch of the C-shaped block in the first opening faces one side of the second through hole, and the notch of the C-shaped block in the second opening faces the second end.

[0008] By adopting the above technical solution, when the C-shaped block presses the spring downward, the card can be taken out from the notch of the C-shaped block, which is very convenient.

[0009] As a further configuration of the utility model, the support member includes two support plates arranged at intervals, the first end and the second end of the two support plates are fixedly connected to a support rod and are respectively provided with a first through hole and a second through hole, in the first end, the first through hole is located on the outside and the support rod is located on the inside, in the second end, the second through hole is located on the inside and the support rod is located on the outside.

[0010] By adopting the above technical solution, the structure is stable and the production cost is low.

[0011] The beneficial effects of the utility model are:

[0012] The utility model connects the support member and the lifting valve through an interlaced rod to form a hinge, and then presses the support member downward to press the spring, so that the card can be taken out conveniently, and the lifting valve can be plugged in conveniently. The utility model has a simple structure, is easy to use, and can be manufactured as a whole. BRIEF DESCRIPTION OF THE DRAWINGS
