Problems solved by technology

[0005] In view of the above problems, the present invention provides a two-way linear hole opener for explosion-proof edge wood. First, it is accurately positioned by the stabilizing cylinder, and then two-way holes are opened by the inner hole knife and the outer hole knife. When the hole is about to be completed, it can be reversed from the back of the board To open holes, which solves the problem that the wood is easy to burst and damage when opening holes with ordinary hole saws

Abstract

The invention relates to the technical field of hole saws, and specifically discloses a two-way linear hole saw for explosion-proof edge wood, including: a drill bit, a drill rod, a stabilizing cylinder, an outer hole opening knife, a shrapnel device, a spring, a bearing, and a sliding sleeve; the drill bit is installed on the The front end of the drill pipe is described; when the outer hole cutter is fully closed, there is a space between the upper inner hole cutter. When the outer hole cutter is fully opened, the diameter is the same as the diameter of the inner hole cutter. Then use the inner hole knife and the outer hole knife to open holes in two directions. When the hole is about to be completed, the hole can be reversed from the back of the board, which can prevent the wood from being damaged by bursting and save wood. The hole saw is not easy to slide during operation, and the processing and positioning accuracy is improved. The hole opener of the present invention is not only explosion-proof and accurate in positioning, but also stable and durable, with low failure rate and long service life.

Description

technical field [0001] The invention relates to the technical field of hole saws and woodworking machinery, in particular to a two-way linear hole saw for explosion-proof edge wood. Background technique [0002] Wooden boards are wooden boards made of complete wood. These boards are durable and have natural textures. They are the best choice for decoration. This type of board is expensive. For: solid wood board, composite board, plywood, blockboard, MDF, etc. Wood board is a material often used in home decoration. In the process of making wood board into furniture or other utensils, it is usually necessary to open holes. In the past, master carpenters Most of them are drilled manually, the speed of opening is slow, and the drilled holes are not round and have large deviations. With the advancement of science and technology, the emergence of hole saws has improved the working efficiency and processing accuracy of the holes, but ordinary hole saws Often there is a problem of ...
