Wood chipping chisel

Abstract

The invention discloses a wood chipping chisel (10). The wood chipping chisel (10) is provided with a chipping chisel body (12) for extending in a length direction (L) of the wood chipping chisel (10), and a handle (14), wherein the front end part of the chipping chisel body (12) is a chisel edge (16); the chisel edge (16) is transited to the chipping chisel body (12) through an inclined front chisel surface (18); the front chisel surface (18) is gradually increased from the chisel edge (16) to the chipping chisel body (12) corresponding to the inclined angle of the length direction (L); a convex rib (20) is arranged on the chipping chisel body (12), and is projected on the side surface of the chipping chisel body (12) to limit the maximum width of the chipping chisel body (12) perpendicular to the length direction (L); and the convex rib (20) is deflected tangentially corresponding to the length direction (L) to form a wave shape in the length direction (L). The wood chipping chisel is not easy to block.

Description

technical field [0001] The invention relates to a hand tool, in particular to a wood chisel. Background technique [0002] The traditional wood chisel is the main tool for combining wood structures in traditional woodworking techniques. It is used for gouging holes, hollowing out, picking grooves, and shoveling, and is widely used in woodworking. Whenever woodworking is required, a wood chisel is used. Among them, the flat chisel, also known as the plate chisel, has a flat chisel blade and is mainly used to chisel square holes. The angle of the chisel blade of the wood chisel is formed by the front chisel surface and the rear chisel surface. When the wood chisel is working, the chisel blade should first cut into the wood surface vertically, cut off the wood fibers, and then move forward to cut the wood. pick out. The structure of the chisel edge and the front chisel surface of the existing wood chisel makes the resistance of the wood chisel increase as the cutting depth i...

AI Technical Summary

Problems solved by technology

The structure of the chisel edge and the front chisel surface of the existing wood chisel makes the resistance of the wood chisel increase as the cutting depth increases, so the cutting depth will be controlled when cutting, but the cutting depth They are all controlled by humans. It is easy to pry the wood other than the end of the square hole when picking out the sawdust, which affects the quality of processing.

Therefore, when drilling, there will be repeated actions, especially when cutting out, it will return to repeat the vertical cutting action, which will affect the efficiency and quality of processing

[0003] In addition, when the wood chisel goes deep into the wood, the wood chisel is easily clamped inside the wood due to the large internal stress of the wood, so the user needs a lot of effort to pull the wood chisel out of the wood
