2. Two slide bars are parallel with the gear engagement section, and mutual collision when effectively avoiding the slide bar to remove produces the skew when preventing fan-shaped sword centre gripping, can keep gear pole and ring gear closely laminating through F shape support, improves the rotation accuracy of ring gear.

3. The limiting rod is in linear motion along the limiting ring, so that the elliptical ring is in linear motion when moving, the matching degree of the elliptical ring and the row teeth is improved, the rotation of the rotary disc is controlled by the driving motor, the motor driving motor runs along the same direction all the time, and the equipment abrasion is effectively reduced.

4. The knife grooves formed in the clamping blocks can improve the clamping effect of the middle holes of the fan-shaped knives, prevent the fan-shaped knives from moving up and down, improve the clamping stability and ensure the sharpening precision.
