At the same time, the upper arc-shaped plate 17 gradually approaches the driving rod 14. When the lower arc-shaped plate 17 separates from the driving rod 14, the first spring 16 continuously releases its force to drive the pressure plate 15 and the driving rod. 14 rises, thereby driving the piston 12 to rise. When the upper arc-shaped plate 17 conflicts with the driving rod 14, the driving rod 14 is driven to descend, thereby driving the pressure plate 15 to descend, compressing the first spring 16 to deform it to generate force, and at the same time driving the piston 12 down.

As shown in Figure 1-2, the correction component includes a screw rod 18. There is a mounting slot on the top of the base 1 and below the plate body 3.

The control process of the correction sensor 22, the controller 21 and the motor 19 is an automatic control technology in the existing technology. The principles are the same and the arrangement is known to those skilled in the art.

As shown in Figure 1, Figure 2 and Figure 5, a rotating column is rotatably installed in the top middle of the slider 20. The top of the rotating column is fixedly connected to the plate body 3. A first torsion spring 23 is set on the outside of the rotating column. Both ends of the spring 23 are fixedly connected to the slider 20 and the plate body 3 respectively. An arc plate 24 is fixedly installed on the top of the base 1 through a vertical rod. A transmission assembly for driving the circular plate 5 to rotate forward is provided above the arc plate 24 , a stopper 28 is fixedly installed on the side of the top of the base 1 close to the body 2. The stopper 28 conflicts with the plate body 3. The stopper 28 can limit the plate body 3 so that it can stop when it collides with the plate body when it is rotated and reset. 3 rotates forward, driving the rotating column to rotate accordingly, and at the same time pulling the first torsion spring 23 to deform and generate force. During the rotation of the plate body 3, it cooperates with the transmission assembly to drive the circular plate 5 to rotate forward, thus driving the bearing 34 and the rotating shaft 6 , the rotation of the connecting block 7, the limit plate and the rewinding roller 8 enables the switching of the upper and lower rewinding rollers 8 to be completed.

When the circular plate 5 rotates with the plate body 3 and the rotating column, the second teeth 27 on the circular plate 5 mesh with the first teeth 25. Due to the protrusion The existence of 26 makes it impossible for the first teeth 25 to reverse, so that the cooperation between the second teeth 27 and the first teeth 25 drives the circular plate 5 to rotate forward, thereby realizing the rotation of the winding roller 8, so that switching is performed. When the plate body 3 is rotated and reset, the circular plate 5 will move accordingly. Due to the existence of the limiting component, the circular plate 5 cannot be reversed.

When the column rotates, the second teeth 27 on the circular plate 5 mesh with the first teeth 25. Due to the existence of the protrusion 26, the first teeth 25 cannot be reversed, so that the second teeth 27 and the first teeth 25 The cooperation drives the circular plate 5 to rotate forward, thereby driving the rotation of the bearing 34, the rotating shaft 6, the connecting block 7, the limiting plate and the winding roller 8, so that the switching of the upper and lower winding rollers 8 can be completed, and at the same time the circular plate 5 rotates forward The lower arc-shaped plate 17 is driven to gradually separate from the driving rod 14, and at the same time, the upper arc-shaped plate 17 gradually approaches the driving rod 14. When the lower arc-shaped plate 17 separates from the driving rod 14, the first spring 16 continuously releases the force. The pressure plate 15 and the driving rod 14 are driven to rise, thereby driving the piston 12 to rise. When the upper arc plate 17 conflicts with the driving rod 14, the driving rod 14 is driven to fall, thereby driving the pressure plate 15 to fall and compressing the first spring 16 to cause deformation. The force simultaneously drives the piston 12 down. When the piston 12 rises, the lubricating oil is sucked into the cavity. At this time, the one-way valve in the injection pipe 13 is closed, the one-way valve in the suction pipe is opened, and the lubricating oil in the box 11 enters through the suction pipe. The replenishment is completed in the cavity. When the piston 12 descends, the lubricating oil in the cavity is squeezed outward. At this time, the one-way valve in the injection pipe 13 opens, the one-way valve in the suction pipe closes, and the lubricating oil enters the barrel through the injection pipe 13. In the body 9, the lubricating oil then flows into the bearing 34 below through the guide tube 10 to replenish the lubricating oil to the bearing 34 that has just been switched, which can avoid the lack of lubricating oil causing noise when the bearing 34 rotates. The winding roller 8 and the connected bearing 34 can be switched to avoid excessive burden caused by continuous use of the same bearing 34. After the switching is completed, the plate body 3 is released, and the first torsion spring 23 releases the force to drive the plate. The body 3 quickly rotates and resets, so that it can drive the support plate 4, the ring plate and the circular plate 5 to rotate and reset accordingly. At the same time, it can generate centrifugal force to throw the lubricating oil injected into the bearing 34 into the bearing 34, so that the lubricating oil can enter more fully. In the bearing 34, during the resetting process of the circular plate 5, the circular plate 5 cannot be reversed due to the presence of the limiting component. The second teeth 27 on the circular plate 5 conflict with the first teeth 25 to drive the first teeth 25 forward. rotate, and then drive the installation shaft to rotate and pull the second torsion spring to deform and generate force, causing the first teeth 25 and the second teeth 27 to be misaligned, so that the disc 5 will not rotate during the reset process. When the second torsion spring is reset, The teeth 27 leave the first teeth 25. At this time, the second torsion spring releases its force to drive the installation shaft and the first teeth 25 to reset.
