Problems solved by technology

Use this kind of groove for walls and other buildings, because it is not a tool for groove, on the one hand, this kind of percussion drill drills the groove through the vibration of the drill bit to impact the wall when groove, and damages the wall The force is very large, and the power consumption is particularly large, and the labor intensity of the workers is also very high; The project of buried pipe cable has caused great impact. First, it increases its workload, and second, it affects the restoration quality of the wall surface; and its work efficiency is low, and the construction quality is poor. , relatively high construction cost

Embodiment Construction

[0016] In order to further understand the technical solutions of the present invention, the present invention will be further described by the following embodiments in conjunction with the accompanying drawings.

[0017] like Figure 1-5 shown. The grooving tool in this example includes a shank 1 and a grooving cutter head connected to the shank 1 . The free end of the shank 1 is provided as a square connecting portion 4 connected with a corresponding driving device. The bottom wall (ie, the outer wall surface of the bottom wall or the outer wall surface and the inner wall surface of the bottom wall) 17 of the groove of the grooved cutter head 2 is arc-shaped in its cross section.

[0018] The grooved cutter head 2 is bent to one side at an angle to the axis of the shank 1 , and in this example, the bending angle 5 of the grooved cutter head 2 relative to the shank 1 is 10-30 degrees.

[0019] The end face of the edge 3 of the grooved cutter head 2 is inclined from the bott...

Abstract

The invention discloses a grooving tool which comprises a handle rod and a corresponding tool bit. The tool bit comprises a groove type chisel head connected to the handle rod, and the groove type chisel head is bent towards one side by one angle relative to the axis of the handle rod. The grooving tool is simple and reasonable in structure, convenient to use and high in construction efficiency and construction quality, and the influence on and the damage degree of constructed objects are small.

Description

technical field [0001] The invention relates to a building decoration tool, in particular to a slotting tool. Background technique [0002] For the decoration and decoration of houses and buildings, the installation of water and electricity is a basic engineering project. The installation of water and electricity pipes and cables in existing water and electricity installations usually uses impact drills specially used for drilling holes to excavate walls, etc. Water and electricity pipes and cables Embedded groove. Use this kind of groove for walls and other buildings, because it is not a tool for groove, on the one hand, this kind of percussion drill drills the groove through the vibration of the drill bit to impact the wall when groove, and damages the wall The force is very large, and the power consumption is particularly large, and the labor intensity of the workers is also very high; The project of buried pipe cable has caused great impact. First, it increases its wor...
