Description

Technical Field

[0001] The utility model relates to the technical field of single board repair auxiliary devices, and in particular to a device for alleviating arm fatigue during single board repair. Background Art

[0002] Veneer repair is the process of repairing, splicing, patching, and other processing of defects in veneers that do not meet standard requirements, such as dead knots, decay, cracks, defects, and other material and processing defects. During the veneer processing and production process, workers use repair tools to repair defects and stains on the surface of the board to make the board smooth and beautiful, which can improve the economic and use value of the veneer and extend its service life.

[0003] The veneer repair equipment is a necessary tool for veneer repair work, and is generally handheld. In the process of veneer repair, workers not only have to hold heavy tools, but also need to keep their arms suspended in the air. Long-term use makes the arms tired, so auxiliary tools are usually used to support the workers' arms. However, when the auxiliary tools are used, they are usually clamped and fixed on the veneer before supporting and assisting the workers' arms. However, when the auxiliary tools are clamped and fixed on the veneer, the stability is poor, and the angle adjustment is inconvenient, so the scope of application and convenience of use are poor.
