Wood drilling tool

Abstract

The invention belongs to the technical field of wood drilling, and particularly relates to a wood drilling tool. The tool comprises a drill barrel module and an impact drill body, wherein the drill barrel module is detachably installed on an output shaft of the impact drill body. Whether two clamping blocks are matched with two clamping grooves or not can be controlled by controlling the two clamping blocks to slide in the radial direction of a drill barrel, when the two clamping blocks are matched with the two clamping grooves, the impact drill body is controlled to conduct rotary output, theoutput shaft of the impact drill body rotates to drive a connecting rotary shaft to rotate, the connecting rotary shaft rotates to drive the two clamping blocks to rotate around the axis of the drillbarrel through cooperation of the clamping blocks and the clamping grooves, the two clamping blocks rotate to drive a mounting block to rotate, the mounting block rotates to drive the drill barrel torotate, and wood drilling treatment is achieved. After the drill barrel is jammed, internal wood is broken through an internal impact rod, so that the drill barrel restores the capability of continuously drilling, it is guaranteed that the inner wall of a drilled round hole is smooth and free of damage, and a good anti-jamming effect is achieved.

Description

[0001] Technical field [0002] The invention belongs to the technical field of wood drilling, in particular to a wood drilling tool. Background technique [0003] Wood is a natural green environmental protection material, suitable for all kinds of decoration styles. It is what people pursue to have a healthy, green and comfortable living environment; and wood products have the following advantages: [0004] First, precious wood will form a unique and beautiful texture due to differences in climate, soil and tree species in the natural growth environment. After careful design and processing, it is beautiful. [0005] Second, wood is a naturally porous material; therefore, wooden doors have good sound insulation. It is not difficult for friends who like wooden furniture to find that their residence has less echo and better sound insulation. This kind of living space can give people a comfortable and quiet feeling. [0006] Third, natural wood will give off an aromatic smel...

Problems solved by technology

[0008] In the process of wood processing, the processing of large round holes is often involved, and cylindrical drills are generally used; because during the processing of cylindrical drills, the inner and outer circular surfaces of the drill are subject to greater friction, so the drill is prone to jamming In the current situation, one of the current technologies is to increase the power of the percussion drill body, which will increase the cost; the other is to tap and exit, which will damage the hole wall during the exit process and affect the quality of the formed hole
