Since the wear-resistant plates on the left and right sides act on the slotted slices, the force on the slotted slices can be uniform;

When using the device of the present invention, since there is a gap between the control rod and the connecting rod, the operator's hand is allowed to pass through the gap to pull the control rod upward;

When the control lever slides upward relative to the lifting rod, it can drive the sliding block to slide upward, so that the connecting rod can drive the central axis and the sliding plate to move upward. The wear-resistant sheet breaks away from the fit of the slotted slice and allows the slotted slice to rotate for slotting work;

After the slotting is completed, stop the driving machine and release the control lever, the locking block is pressed inward under the action of the tension spring to make the wear-resistant sheet and the slotted slice resist, so that the slotted slice can be quickly braked;

Since the lifting frame needs to be lifted during the slotting process, the control lever in the device of the present invention is very convenient to use. The device of the present invention is simple in structure, easy to use, high in safety, and greatly reduces potential safety hazards.
