The linkage groove 41 is provided inside the base 1, and a pressing rod 42 is slidably installed at the through hole of the base 1, which can drive the inclined block 44 to move backward when pressed downward, and a return spring 43 is fixedly installed on the top of the base 1, which can reset the pressing rod 42 when pressed, and the end of the return spring 43 away from the base 1 is fixed The bottom of the convex block fixedly mounted on the top of the pressing rod 42 is used for fixing. The bottom inclined surface of the pressing rod 42 is fitted with an inclined block 44, which can drive the L-shaped rod 46 to move at the same time when it is squeezed and moved, and squeeze spring 45. The left side of the squeezing spring 45 is fixedly mounted on the right side of the inclined block 44, which can reset the L-shaped rod 46 and the inclined block 44. The end of the squeezing spring 45 away from the inclined block 44 is fixedly mounted on the right side of the inner wall of the linkage groove 41. The right side of the inclined block 44 is fixedly mounted with an L-shaped rod 46. The back side of the L-shaped rod 46 is slidably mounted on the front side of the linkage groove 41 for guiding the L-shaped rod 46. The front side of the L-shaped rod 46 is fixedly mounted with a first inclined surface block 47, which can squeeze the second inclined surface block 410 when the L-shaped rod 46 moves, so that the pushing rod 46 The rod 49 moves, and a telescopic spring 48 is fixedly installed on the front side of the inner wall of the linkage groove 41, which is convenient for installing the push rod 49 and can drive the push rod 49 to reset. The push rod 49 is fixedly installed on the end of the telescopic spring 48 away from the linkage groove 41, which can drive the fixed column 414 to move. A second inclined surface block 410 is fixedly installed on the back side of the push rod 49, which can be squeezed by the first inclined surface block 47 to drive the push rod 49 to move. The bottom of the back groove of the push rod 49 is slidably installed with left and right sliders 411, which can push the moving block 413 to move left and right. The right side of the left and right sliders 411 is rotatably connected with a first bolt 412, which can drive the left and right sliders 411 to move left and right. The outer wall of the first bolt 412 is threadedly connected to the right side of the push rod 49 to fix it. The movable block 413 is slidably installed on the left side of the left and right sliders 411, which is convenient for installing the fixing column 414. The fixing column 414 is fixedly installed on the front of the movable block 413 and can be inserted into the positioning hole 417 to fix the valve body 3. The upper and lower sliders 415 are slidably installed on the top of the movable block 413, which can push the movable block 413 to move up and down. The back of the upper and lower sliders 415 slides on the front of the push rod 49 groove. The top of the upper and lower sliders 415 is rotatably installed with a second bolt 416, which can drive the upper and lower sliders 415 to slide up and down when rotating. The push rod 49, the first bolt 412, and the second bolt 416 are provided in two groups, and are symmetrical with the central symmetry axis of the front side of the base 1, and are symmetrically distributed at the front and rear ends of the base 1.One side of the valve body 3 can be fixed, and two groups of push rod 49, first bolt 412, and second bolt 416 are provided, and are symmetrically distributed at the left and right ends of the base 1 with respect to the central symmetry axis of the side of the base 1. The other side of the valve body 3 can be fixed, and the outer wall of the second bolt 416 is threadedly connected to the top of the push rod 49, and a positioning hole 417 is opened on the side of the bottom plate of the bottom of the valve body 3 to facilitate the insertion of the fixing column 414.

[0025] Working principle: when installing the valve body 3, by pressing the pressing rod 42, the return spring 43 is compressed, so that the inclined surface at the bottom can squeeze the inclined block 44 to move backward, and the squeezing spring 45 is compressed. When the inclined surface moves, it will drive the L-shaped rod 46 to move backward. At the same time, the first inclined surface block 47 on the L-shaped rod 46 squeezes the second inclined surface block 410 to move the push rod 49 to the left and right sides, so that the push rod 49 moves left and right, and the telescopic spring 48 is compressed, and then the valve body 3 is put in, and then the pressing rod 42 is loosened, the telescopic spring 48 is reset to drive the push rod 49 to reset, and the fixing column 414 is inserted into the positioning hole 417, so that the valve body 3 can be fixed, and the squeezing spring 45 will also drive the inclined block 44 and the L-shaped rod 46 to reset, and the return spring 43 will drive the pressing rod 42 to reset. In this way, you only need to press the pressing rod 42 to install the valve body 3, so that one person can install the valve body 3.

[0026] The positioning hole 417 is drilled in advance, and may be drilled crookedly, resulting in the inability to insert the fixing column 414. By rotating the first bolt 412, the left and right sliders 411 are moved, and the moving block 413 is pushed to move left and right at the same time. The top of the moving block 413 slides on the upper and lower sliders 415 at this time, so that the left and right position of the moving block 413 can be adjusted. The upper and lower sliders 415 can be moved up and down by rotating the second bolt 416, and the moving block 413 is pushed to move up and down at the same time. The side of the moving block 413 slides on the side of the left and right sliders 411 at this time, so that the up and down position of the moving block 413 can be adjusted. This can prevent the situation where the fixing column 414 cannot be inserted into the positioning hole 417 due to the crooked positioning hole 417.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
