One end of the outer surface of the limit block 23 is slidably connected to the fixed plate 6 through a groove at one end of the inner surface of the fixed plate 6, so as to limit the clip 22 and the sliding column 24 to prevent the clip 22 and the sliding column 24 from sliding off and causing damage to the fixture. A sliding column 24 is fixedly provided in the middle of one side of the clip 22, and one end of the outer circumferential surface of the sliding column 24 is slidably connected to the rotating plate 5 through an empty groove at one end of one side of the rotating plate 5.

One end of the outer circumferential surface of the rotating rod 9 is plugged into the middle thread of one side of the threaded barrel 11 through a threaded structure, and a limiting plate 13 is fixedly arranged at one end of the outer circumferential surface of the threaded barrel 11. One end of the outer surface of the limiting plate 13 is slidably connected to the outer shell 7 through a groove on one side of the outer shell 7, so as to limit the threaded barrel 11 and prevent the threaded barrel 11 from rotating with the rotating rod 9. The clamping plate 12 is moved, causing the position of the clamping plate 12 to change, and the output shaft 3 is no longer fixedly connected. A clamping plate 12 is fixedly set on one side of the threaded barrel 11, and one side of the side plate 1 is fixedly connected to one end of one side of the fixed plate B14. A rotating rod 2 15 is rotatably set on one end of one side of the fixed plate B14. A limiting ring 2 16 is fixedly set on one end of the outer circumference of the rotating rod 2 15. The outer circumference of the limiting ring 2 16 is rotatably connected to one end inside the fixed plate B14 to limit the rotating rod 2 15 to prevent the rotating rod 2 15 from sliding and deviating, thereby increasing the stability of the movement of the rotating rod 2 15.

[0027] During use, when the workpiece needs to be fixed, the rotating control rod 21 drives the rotating rod 2 15 to rotate through the connecting belt 20, and the rotating rod 2 15 drives the clamping plate 2 18 to move through the threaded tube 2 17, and then the clamping plate 2 18 fixes the housing 7, and the rotating rod 1 9 drives the clamping plate 12 to move through the threaded tube 11, so that the clamping plate 12 is separated from the output shaft 3, and then the workpiece is placed between the clamping pieces 22, and the starting motor 2 is used as a power to drive the connecting column 4 to rotate through the output shaft 3, and the connecting column 4 drives the rotating plate 5 to rotate, and the rotating plate 5 drives the sliding column 24 to move through the empty groove on one side, and the sliding column 24 then drives the clamping piece 22 to use the empty groove on one side of the fixed plate 6 as a track. The track slides, and then the clamping piece 22 clamps and fixes the workpiece. When the workpiece needs to be turned over during the processing, the control rod 21 is rotated to drive the clamping plate 2 18 to move, and the fixing restriction of the clamping plate 2 18 on the shell 7 is cancelled. Then, the rotating rod 19 is rotated to drive the clamping plate 12 to move, so that the clamping plate 12 presses one end of the outer circumference of the output shaft 3, and the friction resistance between the clamping plate 12 and the output shaft 3 enables the shell 7 and the output shaft 3 to rotate synchronously. Then, the motor 2 is started to drive the shell 7 to rotate through the output shaft 3, and the shell 7 drives the clamping piece 22 to rotate through the fixing plate 6, and the clamping piece 22 drives the workpiece to rotate. After the workpiece is rotated to a suitable angle, the motor 2 can be turned off.
