The size of the protective cover 309 is larger than that of the grinding sheet 304.

[0024] The effect achieved by the entire embodiment 1 is that when it is necessary to grind a workpiece of a construction project, the workpiece to be grinded can be placed on the surface of the operating table 1 and fixed by the clamping device. Then the grinding motor 303 can be started to drive the grinding disc 304 to rotate, and the electric push rod 301 can be turned on to push the lifting box 302 to move downward. When the protective cover 309 contacts the surface of the workpiece, the electric push rod 301 can continue to push the lifting box 302 to move downward. At this time, the push rod 305 will squeeze the spring 308 through the top block 306, so that the protective cover 309 can always cover the surface of the workpiece, and the grinding disc 304 will continue to move downward under the push of the electric push rod 301 and grind the surface of the workpiece. Grinding, the debris generated by grinding will be covered and isolated by the protective cover 309, and the material of the protective cover 309 is transparent PVC material. When in use, it does not affect the operator's observation of the grinding sheet 304. When the grinding is completed, the contraction function of the electric push rod 301 is started to drive the grinding sheet 304 to move downward. At this time, the spring 308 will also be reset when not squeezed, and the protective cover 309 will move upward together with the lifting box 302, waiting for the next rust removal and grinding, and the debris isolated by the protective cover 309 will also remain on the surface of the workpiece, and the debris left on the surface can be cleaned up, thus avoiding the problem of debris flying around during grinding to cause physical injury to the operator, thereby improving the safety of the operator.

[0025] Example 2, as Figure 1 、 Figure 2 and 5As shown, the four corners of the bottom of the operating table 1 are connected to adjustment components 4, and the adjustment component 4 includes a fixed block 401.

The bottom of the threaded rod 403 is connected to an adjustment block 404, and the bottom of the adjustment block 404 is connected to a supporting foot 405. The outer surface of one side of the supporting foot 405 is connected to a wrench 406.

[0026] The effect achieved by the entire embodiment 2 is that when the operating table 1 is placed on an uneven ground, the wrench 406 at the corresponding position can be turned, so that the wrench 406 can drive the threaded rod 403 to rotate through the adjusting block 404, so that the threaded rod 403 can be threadedly rotated with the fixed block 401 through the threaded hole 402, and then the height of the support legs 405 can be adjusted while the threads are rotated, ensuring that the four sets of support legs 405 can all contact the ground, thereby improving the stability of the operating table 1 during grinding and rust removal.

[0027] Working principle: When the workpiece needs to be derusted and polished, the polishing area can be covered by the protective cover 309, and the elasticity of the spring 308 itself allows the polishing disc 304 to continue to descend to polish the workpiece, ensuring that the protective cover 309 can isolate the debris to prevent the debris from flying around and causing physical harm to the operator, thereby improving the safety of the operator. When the operating table 1 is placed on an uneven ground, the height of the support feet 405 can be adjusted by rotating the thread to ensure that the four sets of support feet 405 can all contact the ground, thereby improving the stability of the operating table 1 during polishing and rust removal.
