[0002] Cutting machines are divided into knife cutting machines, flame cutting machines, plasma cutting machines, laser cutting machines, water jet cutting machines, etc. according to their cutting methods. Knife cutting machines are more common in life and are usually used to cut materials such as metal plates, wood boards or stone slabs. In order to meet the seven requirements of plates of different thicknesses or when cutting grooves on plates, the blade depth of the knife cutting machine needs to be adjustable.

[0003] When adjusting the depth, the limit block is fixed on the ruler by tightening the screw knob, and the limit block is fixed by friction. When the locking force of the screw knob is insufficient, displacement may occur due to insufficient friction, especially when the impact force of the tool is large, which will affect the cutting depth.
