Through grooves are provided on the outside of the four box bodies 2 10. Pistons 2 11 are slidably provided inside the four box bodies 2 10. The outsides of the four pistons 2 11 are fixedly connected to moving rods 12. The four moving rods 12 respectively pass through the four through grooves and are slidably connected thereto. The outer ends of the four moving rods 12 are fixedly connected to clamping blocks 13. Pipes 14 are fixedly embedded in the inside of the four box bodies 2 10. The ends of the four pipes 14 are fixedly embedded on both sides and the front and back sides of box body 1 6 respectively.

[0034] A circular ring 15 is fixedly connected to the bottom of the rotating platform 4, and a plurality of protrusions 16 are fixedly connected to the inner wall of the circular ring 15;

[0035] The four clamping blocks 13 are all made of rubber material, and the four pipes 14 all pass through the base block 2 and the bottom plate 1 and are fixedly connected thereto;

[0036] In this embodiment, when the position change of the workpiece is completed, the electric push rod 9 can move the piston 1 7 upward, and then the air in the box 1 6 can enter the four box 2s 10 under the action of the pipe 14, so that the four blocks 13 will contact the convex strips, and then can apply pressure to the ring 15 and the rotating table 4, thereby preventing the rotating table 4 from rotating;

[0037] Among them, in order to realize the purpose of rotating the rotating table 4, this device adopts the following technical solutions: a round rod 17 is sleeved on the outside of the circular ring 15, a plurality of connecting rods 18 are fixedly connected between the round rod 17 and the circular ring 15, a motor 19 is fixedly connected to the bottom of the bottom plate 1, the output shaft of the motor 19 is fixedly connected to the rotating shaft 1 20, a bevel gear ring 21 is fixedly connected to the bottom of the rotating block 3, a bevel gear 22 is provided at the bottom of the bevel gear ring 21 and meshed with it, and the bevel gear 22 is meshed with the bevel gear ring 21;

[0038] Among them, in order to achieve the purpose of air backflow, this device adopts the following technical solution: the four pipes 14 are each provided with an electronic switch valve 23, which can prevent the air backflow in the box body 2 10;

[0041] The use process of the utility model is as follows: when using the utility model, the workpiece to be machined is placed on the workbench, and then a handheld cutting machine or a handheld polishing machine is used manually to machine the workpiece. During machining, the motor 19 is controlled to work, and the motor 19 drives the rotating shaft 20 to rotate. The rotation of the rotating shaft 20 drives the bevel gear 22 to rotate. The rotation of the bevel gear 22 drives the bevel gear ring 21 to rotate. The rotation of the bevel gear ring 21 drives the rotating block 3 and the rotating table 4 to rotate. In this way, the workpiece can be rotated, thereby changing the position of the workpiece. At the same time, the round rod 17 can be manually rotated to rotate the rotating table 4.

[0042] When the position change is completed, the four electronic switch valves 23 are controlled to open, and then the electric push rod 9 is controlled to work to move the piston 1 7 upward. Then, under the action of the four pipes 14, the air in the box 1 6 enters the four box 2 10. After the air enters, the four pistons 2 11, the four moving rods 12 and the four clamping blocks 13 move outward, so that the four clamping blocks 13 will contact the protrusions 16, and then pressure can be applied to the ring 15 and the rotary table 4, thus completing the self-locking, thereby preventing the rotary table 4 from rotating, thereby preventing the workpiece from rotating on the rotating assembly, and thus ensuring the normal processing of the processing;

[0043] After the self-locking is completed, the four electronic switch valves 23 are controlled to close, thereby preventing the air in the second box 10 from flowing back;

[0044] The device is also designed with a controller 24, and the controller 24 is electrically connected to the motor 19, the electric push rod 9 and the four electronic switch valves 23 in the device, so that when in use, the user can control the motor 19, the electric push rod 9 and the four electronic switch valves 23 to work through the controller 24. The controller 24, the motor 19, the electric push rod 9 and the electronic switch valves 23 are very mature products in the existing technology and can be purchased on the market. Therefore, the model, how to electrically connect and the detailed working principle are not described here.
