The card block 7 is slidably connected to the card slot 6. An end block 8 is fixedly connected to the upper end of the valve core body 1. A valve stem 9 is slidably connected to the inner wall of the end block 8. The valve stem 9 contacts the valve core body 1.

[0021] Refer to Figure 1 , Figure 2 , Figure 3 , the sealing ring 5 is slidably connected to the extrusion ring 4, and the sealing ring 5 is slidably connected to the valve core body 1. Through the setting of the extrusion ring 4, the sealing ring 5 can be extruded and positioned. A plurality of card slots 6 are provided, and the plurality of card slots 6 are arranged in a circular array on the sealing ring 5. Through the setting of the card slots 6, it is convenient to cooperate with the card block 7 for clamping use.

[0022] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4, a riveting mechanism 10 is provided on the end block 8. The riveting mechanism 10 includes a fixed cylinder 101. The left end of the end block 8 is fixedly connected to the fixed cylinder 101. A pin rod 102 is slidably connected to the inner wall of the end block 8. The pin rod 102 is slidably connected to the valve rod 9 and also slidably connected to the fixed cylinder 101. A limiting plate 104 is slidably connected to the inner wall of the fixed cylinder 101. The limiting plate 104 contacts the end block 8. The upper end of the limiting plate 104 is fixedly connected to an end plate 105. A spring 106 is welded to the lower end of the end plate 105. The other end of the spring 106 is welded to the end block 8. An elastic protective sleeve 107 is arranged outside the spring 106. Through the arrangement of the pin rod 102, the valve rod 9 can be inserted, and under the action of structures such as the spring 106 and the limiting plate 104, the pin rod 102 can be limited, thereby ensuring the stable connection between the valve rod 9 and the valve core body 1.

[0023] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , the right end of the pin rod 102 is fixedly connected to an end plate 103. The end plate 103 contacts the end block 8.

[0025] By pulling the end plate 105 upward, the elastic protective sleeve 107 and the spring 106 are deformed. Under the action of the elastic protective sleeve 107, the spring 106 can be protected to avoid the corrosion problem of the spring 106. When the end plate 105 moves, it can drive the limiting plate 104 to move, so that the limiting plate 104 moves away from the end block 8, and the valve rod 9 is pushed into the end block 8. Then, the pin rod 102 is pushed through the end block 8 and the valve rod 9, so that the pin rod 102 is inserted into the fixed cylinder 101. Finally, the end plate 105 is released, and the spring 106 and the elastic protective sleeve 107 return to their original shapes, so as to pull the limiting plate 104 through the pin rod 102 to limit the pin rod 102, and quickly assemble and fix the valve rod 9 and the valve core body 1 for use.
