Description

It is an important foundation for establishing a working and living space. Engraving machines will be used in furniture processing.

[0003] A Chinese patent discloses an engraving machine for furniture processing (authorization announcement number CN220313605U), which limits the furniture board body under the action of a placement groove, and squeezes the connecting plate under the action of a limit spring, so that the connecting plate pushes the inclined limit block, and then the inclined limit block limits the furniture board body, thereby improving the stability of the furniture board body during engraving, and at the same time solves the problem that the existing engraving machine has a poor limiting effect on the furniture board, which causes the furniture board to shake during engraving, resulting in poor furniture engraving. However, according to basic common sense, since the limit spring has a certain elasticity, when the engraving knife acts on the board and applies external force, the limit spring will produce a certain deformation, thereby causing the board to loosen and other problems.
