A protective pad 27 is fixed on the top of the placement plate 4. Both the stabilizing plate 10 and the limiting block 13 are composed of a rectangular plate and an arc-shaped plate.

[0032] Lift this trimming device by holding the grip rod 24. After lifting, the electric push rod 26 can be controlled by pressing the controller 25, so that the height can be automatically adjusted to meet the trimming height, thus improving the trimming effect. When placing the scissors handle, the friction between the handle and the protective pad 27 can be increased, which can improve the stability during placement.

[0033] Working principle: When in use, the staff first places one side scissors handle on the placement plate 4. At this time, the extrusion arc plate 8 is squeezed by the bolt 1, and then the scissors handle can be fixed. When fixing, because the space range is not limited, scissors handles of various sizes can be fixed. After fixing, the other side of the scissors handle is bundled and fixed by the elastic bandage 23. After fixing, the hydraulic rod 21 drives the connecting rod 22 to move, so as to pull the elastic bandage 23. The elastic bandage 23 drives the two handles of the scissors to move closer to each other, so that the scissors can complete trimming. During trimming, the electric push rod 26 can be directly controlled by the controller 25 to adjust the height of the scissors, thus improving the convenience during trimming.
