The lower end of the return spring 345 is fixedly connected to a base plate 346. A rotating assembly 35 includes a short tube 351. A through - hole 352 is opened inside the short tube 351. A limiting ring 353 is fixedly connected to the upper end of the short tube 351. A rotating column 354 is rotatably connected to the outside of the short tube 351. A curved groove 355 is opened on one side of the rotating column 354. A short rod 356 is fixedly connected to the upper end of the rotating column 354. A column groove 357 is opened inside the rotating column 354.

[0024] As a further implementation of this solution, a stirring rod 2 is fixedly connected inside the semi - gear 31. The central axis of the semi - gear 31 and the central axis of the stirring rod 2 are on the same straight line. There are two semi - gears 31, and the two semi - gears 31 are symmetrically distributed before and after on both sides of the toothed plate 32. Such a design can effectively control the structure of the device and improve the operating efficiency of the device.

[0025] As a further implementation of this solution, the included angle between the toothed plate 32 and the control assembly 34 is 90°. The included angle between the rivet 33 and the toothed plate 32 is 90°. The included angle between the rivet 33 and the control assembly 34 is 90°. The projection of the rivet 33 in the horizontal direction is circular. Such a design is conducive to the transmission of force between devices, can make the device operate more stably, and improves the stability of the device.

[0026] As a further implementation of this solution, the projection of the pressing plate 341 in the vertical direction is rectangular. The included angle between the fixing block 342 and the pressing plate 341 is 90°. There are two curved rods 343, and the two curved rods 343 are symmetrically distributed before and after on the upper end of the pressing plate 341. Such a design can make the device structure more reasonable, facilitate the cooperation between components, and improve the working efficiency.

[0027] As a further implementation of this solution, there are several return springs 345, and each return spring 345 is parallel to each other. The included angle between the return spring 345 and the base plate 346 is 90°. The base plate 346 is parallel to the pressing plate 341. The bottom end surface of the base plate 346 and the bottom end surface of the machine tool 1 are on the same horizontal plane. Such a design is conducive to the transmission of force between devices and improves the operating efficiency of the device.

[0028] As a further implementation of this solution, the included angle between the bottom end of the short tube 351 and the base plate 346 is 90°. The inner side of the through hole 352 fits with the outer side of the limit post 344.

The column groove 357 is cylindrical in shape, and a limit post 344 is rotatably connected to the inner side of the column groove 357. Such a design can improve the fit between the device structures and achieve effective control of the device structure.

[0030] Working process: During the use of the device, when the motor on one side of the machine tool 1 starts to operate, it will drive the stirring rod 2 to rotate. When the stirring rod 2 rotates, it will drive the fixedly connected semi-gear 31 on the outside to rotate. When the semi-gear 31 rotates, it will drive the toothed plate 32 engaged on one side to move. When the toothed plate 32 moves, it will drive the fixed block 342 to move downward through the fixedly connected rivet 33. When the fixed block 342 moves downward, it will drive the pressing plate 341 to move downward. When the pressing plate 341 moves downward, it will drive the fixedly connected curved rod 343 to move downward. At this time, the curved rod 343 will exert pressure on the curved groove 355. Since the limiting ring 353 restricts the movement of the rotating column 354, the rotating column 354 will rotate on the outside of the short tube 351. When the rotating column 354 rotates, it will drive the short rod 356 fixedly connected to the upper end to rotate. When the short rod 356 rotates a certain angle, it will contact the stirring rod 2 and cause the stirring rod 2 to vibrate. This can disperse the material stuck in the spiral blades of the stirring rod 2 and facilitate material transmission. When the short rod 356 contacts the stirring rod 2, the semi-gear 31 has rotated a certain angle and is no longer engaged with the toothed plate 32. At this time, the elastic force generated by the restoration of the deformation of the return spring 345 pushes the pressing plate 341 upward. The pressing plate 341 moves upward, driving the fixed block 342 to move upward. The fixed block 342 moves upward to drive the toothed plate 32 to reset.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
