When the connecting screw 41 is installed in place, the limit spring 22 resets so that the limit block 23 limits and blocks the connecting screw 41, thereby ensuring the convenience of equipment use and improving installation efficiency.

[0041] Specifically, a return spring 26 is provided inside the fixing frame 25 corresponding to the connecting screw 41 , and one end of the return spring 26 is connected to a return plate 27 .

[0042] By adopting the above technical solution, when it is necessary to separate the connecting screw 41 and the front clamping plate 14, the rectangular rod 21 is pulled to drive the limit block 23 to move, and at the same time the reset spring 26 drives the reset plate 27 to push the connecting screw 41 out of the positioning groove 24, thereby ensuring the convenience of equipment use and improving positioning efficiency.

[0043] When this embodiment is in use: when the connecting screw 41 is inserted into the interior of the front clamping plate 14, the connecting screw 41 is inserted into the positioning groove 24, and at the same time, the connecting screw 41 abuts against one side of the limit block 23 and causes the limit spring 22 to be compressed. When the connecting screw 41 is installed in place, the limit spring 22 resets so that the limit block 23 limits and blocks the connecting screw 41, ensuring the convenience of equipment use. When it is necessary to separate the connecting screw 41 from the front clamping plate 14, the rectangular rod 21 is pulled to drive the limit block 23 to move, and at the same time, the reset spring 26 drives the reset plate 27 to push the connecting screw 41 out of the positioning groove 24, thereby improving positioning efficiency.

[0044] Example 3

[0045] The difference between this embodiment and embodiment 1 and embodiment 2 is that: specifically, the positioning and disassembly component 8 includes a T-shaped slide rail 82, a mounting seat 83, a positioning screw 84, a positioning spring 85 and a guide rod 86, wherein a guide rod 86 is installed inside the base plate 5, a positioning spring 85 is provided on the surface of the guide rod 86, a positioning screw 84 is provided at one end of the positioning spring 85, a mounting seat 83 is provided at the top end of the positioning screw 84, and a T-shaped slide rail 82 is provided at the top end of the mounting seat 83 corresponding to the front clamping plate 14.

[0046] By adopting the above technical solution, the front clamping plate 14 can be assembled before the equipment is used, and the front clamping plate 14 can be installed along the T-shaped slide rail 82, and then the front clamping plate 14 can be fixed by tightening the bolts 81. At the same time, when the front clamping plate 14 is adjusted, the positioning screw 84 can be slid along the guide rod 86, so that the positioning screw 84 drives the mounting seat 83 and the front clamping plate 14 at its upper end to move. After the valve body 3 is placed, the front clamping plate 14 is loosened. At this time, the positioning spring 85 is reset to drive the front clamping plate 14 to be close to the surface of the valve body 3, ensuring the convenience of initial positioning and improving the stability of subsequent operations.

[0047] Specifically, positioning holes are evenly spaced apart inside the T-shaped slide rail 82 , and fastening bolts 81 are provided inside the front clamping plate 14 corresponding to the positioning holes.

[0048] By adopting the above technical solution, the installation position of the front clamping plate 14 can be selected and then fixed by tightening the bolts 81, thereby improving the installation strength of the equipment and ensuring the quality of use.

[0049] When using this embodiment: before the equipment is used, the front clamping plate 14 can be assembled first, and the front clamping plate 14 can be installed along the T-shaped slide rail 82, and then the front clamping plate 14 can be fixed by fastening the bolts 81. At the same time, when the front clamping plate 14 is adjusted, the positioning screw 84 can be slid along the guide rod 86, so that the positioning screw 84 drives the mounting seat 83 and the front clamping plate 14 at its upper end to move. After the valve body 3 is placed, the front clamping plate 14 is released. At this time, the positioning spring 85 is reset to drive the front clamping plate 14 to be close to the surface of the valve body 3, ensuring the convenience of initial positioning and improving the stability of subsequent operations.

[0050] The working principle and use process of the present invention: When the present invention is used, the front clamping plate 14 can be assembled before the equipment is used, and the front clamping plate 14 can be installed along the T-shaped slide rail 82. Then, the front clamping plate 14 is fixed by the fastening bolt 81. At the same time, when the front clamping plate 14 is adjusted, the positioning screw 84 can be slid along the guide rod 86, so that the positioning screw 84 drives the mounting seat 83 and the front clamping plate 14 at its upper end to move. After the valve body 3 is placed, the front clamping plate 14 is loosened. At this time, the positioning spring 85 is reset to drive the front clamping plate 14 to be tightly attached to the surface of the valve body 3, thereby ensuring the convenience of initial positioning and improving the stability of subsequent operations.

[0051] When fixing the valve body 3, first place the valve body 3 on the upper end of the water receiving tray 7 so that it can directly abut against the O-ring 49 inside the rear clamping plate 48 to ensure the placement of the valve body 3. Then push the front clamping plate 14 to make it fit with the valve body 3. Then rotate the tensioning block 43 along the pin 44 so that the connecting screw 41 is inserted into the interior of the front clamping plate 14. Then rotate the connecting screw 41 so that the front clamping plate 14 is tightly fitted to the surface of the valve body 3.

[0052] When the connecting screw 41 is stuck in the interior of the front clamping plate 14, the connecting screw 41 is inserted into the positioning groove 24, and at the same time, the connecting screw 41 abuts against one side of the limit block 23 and compresses the limit spring 22. When the connecting screw 41 is installed in place, the limit spring 22 resets so that the limit block 23 limits the connecting screw 41 to ensure the convenience of equipment use. When it is necessary to separate the connecting screw 41 from the front clamping plate 14, the rectangular rod 21 is pulled to drive the limit block 23 to move, and at the same time, the reset spring 26 drives the reset plate 27 to push the connecting screw 41 out of the positioning groove 24, thereby improving the positioning efficiency. After the valve body 3 is fixed, water is fed in through the water inlet pipe to flush it at a fixed point, and then the water flows out through the drain pipe 6 at the bottom of the water receiving tray 7.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
