Multifunctional electric tool

Abstract

The invention discloses a multifunctional electric tool. The multifunctional electric tool comprises an electric drill body and an arc-shaped grab handle. One side of the arc-shaped grab handle is provided with a positive and negative rotation transfer switch and an electronic stepless speed regulation switch. The arc-shaped grab handle is provided with a locking button. The electric drill body isinternally provided with a rotary shaft. A metal rotary screw stud and a metal chuck are mounted on the rotary shaft. The metal chuck is internally provided with a fastener used for fastening. An abrasive wheel assembly is mounted on the metal rotary screw stud through a flat key. A double-drill assembly, a polishing wheel assembly, a detachable drill bit assembly and a universal flexible shaft are mounted in the metal chuck in a replaceable mode. The multifunctional electric tool is diversified in function. A carpenter can implement processing of multiple processes through the same electricdrill. The abrasive wheel assembly can be mounted on the metal rotary screw stud conveniently. Standard joints are manufactured on the double-drill assembly, the polishing wheel assembly, the detachable drill bit assembly and the universal flexible shaft so that the double-drill assembly, the polishing wheel assembly, the detachable drill bit assembly and the universal flexible shaft can be mounted in the metal chuck conveniently and fastened. The double-drill assembly, the polishing wheel assembly, the detachable drill bit assembly and the universal flexible shaft can be exchanged and used asrequired, and the cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a multifunctional electric tool. Background technique [0002] Electric drill is a kind of electric tool commonly used, and electric drill in the prior art generally only has the function of drilling, and function is single. Woodworkers often need to use a lot of tools in the decoration process, and they need to constantly replace tools when performing different processes. For example: 1, when needing to drill plank hole, just need to use electric drill, the drill bit of prior art is all one, when the drilling edge of drill bit damages or wears and teares, and drill bit is just scrapped basically, and this situation has caused great The waste also increases a lot of cost. 2. When woodworking is beating furniture, when it is necessary to polish the side rounded corners of the wooden board, it is generally done manually with sandpaper, which is time-consuming and laborious...

AI Technical Summary

Problems solved by technology

For example: 1, when needing to drill plank hole, just need to use electric drill, the drill bit of prior art is all one, when the drilling edge of drill bit damages or wears and teares, and drill bit is just scrapped basically, and this situation has caused great waste, but also increased a lot of cost

2. When woodworking is beating furniture, when it is necessary to polish the side rounded corners of the wooden board, it is generally done manually with sandpaper, which is time-consuming and laborious, and the grinding effect is poor and the roughness is large

3. When it is necessary to polish the surface of the woodworking board, the polishing machine is generally used for the polishing operation, which is troublesome to replace and increases the cost. In addition, the polishing wheel in the polishing machine is easy to produce radial friction during installation and use. and axial shaking, affecting the polishing effect

4. When the hinge needs to be installed, screwdrivers or electric tools are generally used to install the screws, but when installing hinges in some narrow spaces, it is difficult to insert the screwdriver or electric tools, which affects the installation of the screws

5. When the door handle needs to be installed, it is necessary to process two symmetrical mounting holes on the same vertical line. At present, the line is usually drawn first, and then the mounting holes are processed separately. This requires a high level of carpentry experience and timely It is difficult for a skilled carpenter to ensure that the two holes are symmetrical and on the same vertical line
