[0035] Working principle:

[0036] The first driving motor 5 is turned on, and the first driving motor 5 works; when the first driving motor 5 works, the first driving motor 5 drives the first screw rod 3 to rotate; when the first screw rod 3 rotates, the two sliding frames 6 threadedly connected to the first screw rod 3 move close to each other; at this time, the workpiece to be polished is placed between the two housings 12, and as the two sliding frames 6 move close to each other, the clamping rods 15 on the two housings 12 clamp the material; when the clamping rods 15 clamp the material, the plurality of clamping rods 15 shrink along the shape of the material; at this time, the clamping rods 15 extrude the first springs 16, so that the first springs 16 are extruded; and as the clamping rods 15 slide, the lower clamping blocks 17 installed at one end of the clamping rods 15 gradually contact the upper clamping blocks 19; as the clamping rods 15 move, the upper clamping blocks 19 extrude the second springs 21, so that the second springs 21 shrink; when the clamping rods 15 move to the appropriate position, the upper clamping blocks 19 and the lower clamping blocks 17 are movably connected; at this time, the plurality of clamping rods 15 have different lengths along the shape of the material; when people do not need to fix the shape of the clamping rods 15, the adjusting rod 20 is rotated, so that the adjusting rod 20 moves upward; at this time, the upper clamping blocks 19 are located on the upper side of the lower clamping blocks 17; when the clamping rods 15 move, the lower clamping blocks 17 do not contact the upper clamping blocks 19.

[0037] The cooperation of the clamping rod 15 and the first spring 16 in the device enables the device to clamp according to the shape of the material when in use, thereby avoiding the device from clamping loosely or the polishing piece from splashing when polishing due to the different shapes of the material. The cooperation of the upper clamping block 19, the lower clamping block 17, the first spring 16 and the second spring 21 in the device enables the clamping rod 15 to be fixed in different lengths according to the shape of the material, thereby making the device more convenient when polishing multiple same workpieces, and thereby realizing the accurate positioning of the clamp.

[0038] When the material is fixed, the handle 13 can be rotated to drive the screw rod 11 to rotate, thereby changing the angle of the two housings 12, so that the device can clamp the material at different angles. When the material is fixed, the second driving motor 9 can be turned on to drive the rotating column 8 to rotate, at which time the support frame 10 can rotate with the second driving motor 9. Then, the polishing mechanism 22 is opened, the third driving motor 24 and the fourth driving motor 26 are operated, the fourth driving motor 26 drives the polishing wheel 27 to polish the material, and the third driving motor 24 drives the telescopic frame 25 to move.

[0039] The cooperation of the second driving motor 9, the rotating column 8 and the support frame 10 in the device enables the device to rotate fully when in use, thereby enabling the device to polish in multiple directions when polishing, thereby improving the polishing efficiency and quality of the device, avoiding multiple manual reversals, and the air suction fan 28 in the device effectively collects the waste, thereby avoiding the waste from splashing and polluting the environment.
