Description

Technical Field

[0001] The present application relates to scissors production equipment, in particular to a yaw mechanism and a scissor angle grinding adjustable device. Background Art

[0002] When producing scissors, in order to ensure the product dimensions and appearance requirements, it is often necessary to perform water grinding on each surface of the scissors. Grinding the back of the knife is an important process among them. The traditional device for grinding the back of the knife is generally fixed, and can only fix the back of the knife in a vertical state, and then perform water grinding on the back of the knife surface. The edge between the back of the knife surface and the inner and outer surfaces of the blade will be at a right angle, so that it is impossible to perform water grinding on the two chamfers on both sides of the back of the knife, and the appearance of the scissors is insufficient. Summary of the Invention
