[0029] A top plate 2, the top plate 2 is fixedly arranged on the upper end surface of the support rod;

[0030] A grinding assembly is arranged on the top plate 2, and the grinding assembly includes a grinding motor and a grinding disc 4. The grinding disc 4 is rotatably arranged below the top plate 2 by the grinding motor. Both ends of the upper surface of the workbench 1 are provided with strip-shaped sliding holes 101. The workbench 1 is provided with a clamping assembly 3 through the strip-shaped sliding holes 101. A dust collecting assembly 5 is arranged on the upper end of the clamping assembly 3.

[0031] The dust collecting assembly 5 includes a fan 501 , and the fan 501 is arranged on one side of the upper end surface of the top plate 2 .

[0032] Among them; the clamping assembly 3 includes a limit plate 301, a bidirectional screw 302 and a handle 303. The limit plate 301 is sleeved on the middle end of the outer side of the bidirectional screw 302, the upper end of the limit plate 301 is fixedly connected to the workbench 1, the bidirectional screw 302 is rotatably connected to the limit plate 301, and the handle 303 is fixedly set at one end of the bidirectional screw 302. By setting the limit plate 301, it is convenient to install the bidirectional screw 302 and limit the position of the bidirectional screw 302. By rotating the handle 303, the bidirectional screw 302 can be driven to rotate.

[0033] Among them; the threads opened at both ends of the bidirectional screw 302 are in opposite directions, and both ends of the bidirectional screw 302 are threadedly connected with a driving block 304 through the opened threads, and a sliding connection block 305 is fixedly arranged on the upper end of the driving block 304, and the sliding connection block 305 is slidingly connected to the strip sliding hole 101, and a clamping block 306 is fixedly arranged on the upper end surface of the sliding connection block 305. Through the rotation of the bidirectional screw 302, under the limiting action of the sliding connection block 305, the two driving blocks 304 are moved along the bidirectional screw 302, approaching each other or moving away from each other. When the two driving blocks 304 are close to each other, the clamping block 306 can be driven by the sliding connection block 305 to move synchronously and approach each other, so that the clamping block 306 can effectively clamp the valve to ensure the stability of the valve during grinding.

[0034] Among them; the dust collection component 5 also includes a dust box 502, a dust inlet pipe 503 and a connecting hose 504. The dust box 502 is arranged on the lower end surface of the top plate 2 and is located directly below the fan 501.

[0037] Working principle: by rotating the handle 303, the bidirectional screw 302 can be driven to rotate. By rotating the bidirectional screw 302, under the limiting action of the sliding connection block 305, the two driving blocks 304 can move along the bidirectional screw 302, approaching or moving away from each other. When the two driving blocks 304 approach each other, the sliding connection block 305 can drive the clamping block 306 to move synchronously and approach each other, so that the clamping block 306 can effectively clamp the valve to ensure the stability of the valve during grinding.

[0038] Furthermore, by turning on the fan 501, the dust collecting port 505 can effectively collect waste chips generated by grinding. After the waste chips enter the dust collecting port 505, they are connected to the dust inlet pipe 503 through the hose 504, and finally discharged into the dust collecting box 502. By providing the dust collecting box 502, the waste chips generated during the grinding process can be effectively collected and concentrated, which is convenient for subsequent centralized processing and avoids polluting the surrounding environment. In addition, during the movement of the clamping block 306, the dust collecting port 505 can be driven to move synchronously, which can better absorb the waste chips.
