At this time, the ratchet 14 cannot rotate in the opposite direction due to the obstruction of the spring piece 19, so that the workpiece is firmly fixed, and then the workpiece is polished by the polishing assembly. During the polishing process, the workpiece will not shake easily. After polishing is completed, the fixed column 110 is moved so that the spring piece 19 no longer restricts the rotation of the ratchet 14, and then the polished workpiece can be removed. Through the above structure, the workpiece can be clamped and fixed when the workpiece is flexibly polished, so that it will not shake easily during the polishing process, thereby improving the polishing accuracy to a certain extent.

[0024] like Figures 1 to 4As shown, the side wall of the fixed block 17 is provided with a plurality of slots 2; a spring 23 is fixedly connected to the end of one of the plurality of slots 2, and a sliding column 21 is slidably connected to the middle of the remaining slots 2; a clamping block 22 is fixedly connected to the other end of the spring 23; the side wall of the clamping block 22 is fixedly connected to the ends of the plurality of sliding columns 21; grooves of different shapes are respectively provided on both sides of the clamping block 22; when working, the clamping block 22 can be pulled up to separate the side wall of the clamping block 22 from the side wall of the fixed block 17 when necessary, and after the plurality of sliding columns 21 are completely separated from the interior of the slots 2 , rotate the clamping block 22 to reverse the directions of the grooves on both sides of the clamping block 22, then insert the multiple sliding columns 21 into the corresponding slots 2, and then loosen the clamping block 22 so that the clamping block 22 fits with the fixed block 17 under the pulling force of the spring 23. When it is necessary to clamp the workpiece, the directions of the multiple clamping blocks 22 can be adjusted according to the surface shape of the clamped workpiece, so that the multiple clamping blocks 22 can fit better with the surface of the workpiece when clamping the workpiece. Through the above structure, the clamping fit can be increased to a certain extent when clamping the workpiece, thereby making the workpiece more stable when being polished.

[0025] like Figures 1 to 3 As shown, the side wall of the side plate 12 is fixedly connected to a fixed plate 3; the top of the fixed plate 3 is fixedly connected to a motor 31; the output end of the motor 31 is set through the fixed plate 3; the output end of the motor 31 is fixedly connected to a connecting shaft 32; the middle part of the connecting shaft 32 is fixedly connected to a plurality of fan blades 33; the plurality of fan blades 33 are arranged in a circular array in the middle part of the connecting shaft 32; during operation, when the workpiece is polished, a large amount of debris will be generated and fly with the rotation of the polishing mechanism, thereby blocking the line of sight and making it impossible for the operator to accurately judge the grinding condition of the workpiece. At this time, the motor 31 can be started to drive the connecting shaft 32 to rotate, thereby driving the plurality of fan blades 33 to rotate, so that the air flows quickly toward the polishing surface of the workpiece, thereby blowing away the debris generated during polishing and reducing the obstruction to the line of sight. Through the above structure, the debris generated during polishing can be blown away, reducing the obstruction to the line of sight, and thus the polishing condition of the workpiece can be more accurately controlled, further improving the polishing accuracy.

[0026] like Figures 1 to 5 As shown, a liquid tank 4 is fixedly connected to the top of the bottom plate 1; a drainage hole 41 is opened on the side wall of the liquid tank 4; the drainage hole 41 is connected to the interior of the liquid tank 4; a plug 42 is detachably installed in the middle of the drainage hole 41; during operation, liquid is injected into the interior of the liquid tank 4, and then when the workpiece is polished, part of the debris generated is carried downward by the airflow along with the operation of the motor 31, and then falls into the liquid inside the liquid tank 4, so that it cannot fly up again. Through the above structure, the flying debris can be reduced to a certain extent.

[0027] like Figures 1 to 5As shown, a collecting box 5 is detachably installed on the inner side of the liquid tank 4; a connecting rod 51 is fixedly connected to the side wall of the collecting box 5; a filter screen 52 is fixedly connected to the bottom of the collecting box 5; during operation, after the debris generated by polishing falls into the liquid inside the liquid tank 4, it will float on the liquid surface or sink into the liquid. After the polishing of the workpiece is completed, the filter screen 52 can be driven to rise by lifting the connecting rod 51, so that the debris is caught by the filter screen 52 inside the collecting box 5 and separated from the liquid. Through the above structure, the debris can be conveniently collected for subsequent processing.

[0028] like Figure 1 As shown, a pair of guide plates 6 are fixedly connected to the side walls of the side panels 12; the pair of guide plates 6 are located on both sides of the plurality of clamping blocks 22; an observation glass 61 is fixedly connected to the middle of the guide plates 6; when working, when the air is driven to flow by the operation of the motor 31, the pair of guide plates 6 will limit the flow direction of the air, so that the flowing air can blow more debris onto the liquid inside the liquid tank 4. Through the above structure, the flow direction of the air can be restricted, so that more debris can be blown into the liquid inside the liquid tank 4, further reducing the interference of the debris.

[0029] like Figure 4 As shown, a pair of rubber pads 7 are fixedly connected to the side wall of the clamping block 22; the rubber pads 7 are located at a pair of grooves of the clamping block 22 and have the same shape as the grooves of the clamping block 22; during operation, when the workpiece is clamped by multiple clamping blocks 22, the workpiece will come into contact with the rubber pads 7, and the slight deformation of the rubber pads 7 during clamping will increase the fit with the workpiece. Through the above structure, the fit when clamping the workpiece can be further improved, thereby increasing the stability of the workpiece and reducing the damage to the workpiece clamping to a certain extent.

[0030] During operation, the workpiece to be polished is placed in the middle of the plurality of fixed blocks 17, and then the rotating handle 111 is turned to drive the ratchet 14 to rotate, driving the plurality of fixed columns 18 to slide in the middle of the second groove 15, and then driving the plurality of slide blocks 16 to slide in the middle of the corresponding first groove 13, so that the plurality of fixed blocks 17 are moved toward the middle, and then the workpiece to be polished is clamped. At this time, the ratchet 14 cannot rotate in the opposite direction due to the obstruction of the spring sheet 19, so that the workpiece is firmly fixed, and then the workpiece is polished by the polishing assembly. During the polishing process, the workpiece will not shake easily. After polishing is completed, the fixed column 11 is toggled. 0 so that the spring piece 19 no longer restricts the rotation of the ratchet wheel 14, and then the polished workpiece can be removed. If necessary, the clamping block 22 can be pulled up to separate the side wall of the clamping block 22 from the side wall of the fixed block 17. After the multiple sliding columns 21 are completely separated from the interior of the slot 2, the clamping block 22 is rotated to reverse the directions of the grooves on both sides of the clamping block 22, and then the multiple sliding columns 21 are inserted into the corresponding slots 2, and then the clamping block 22 is released so that the clamping block 22 fits with the fixed block 17 under the pulling force of the spring 23. When the workpiece needs to be clamped, the multiple clamps can be adjusted according to the surface shape of the clamped workpiece. The direction of the holding block 22 enables the multiple clamping blocks 22 to fit more closely with the surface of the workpiece when clamping the workpiece. When polishing the workpiece, a large amount of debris will be generated and fly with the rotation of the polishing mechanism, thereby blocking the line of sight and making it impossible for the operator to accurately judge the grinding condition of the workpiece. At this time, the motor 31 can be started to drive the connecting shaft 32 to rotate, thereby driving the multiple fan blades 33 to rotate, so that the air flows quickly toward the polishing surface of the workpiece, thereby blowing away the debris generated during polishing, reducing the obstruction of the line of sight, and injecting liquid into the liquid tank 4, and then when polishing the workpiece, some of the debris generated As the motor 31 runs, it is carried downward by the airflow and then falls into the liquid inside the liquid tank 4, preventing it from flying up again. After the debris generated by polishing falls into the liquid inside the liquid tank 4, it will float on the liquid surface or sink into the liquid. After the workpiece is polished, the filter screen 52 can be driven to rise by lifting the connecting rod 51, so that the debris is caught by the filter screen 52 inside the collection box 5 and separated from the liquid. When the air is driven to flow by the operation of the motor 31, a pair of guide plates 6 will limit the flow direction of the air, so that the flowing air can blow more debris onto the liquid inside the liquid tank 4.
