Problems solved by technology

[0003] In the prior art, the square hole electric drill generally adopts the method of directly installing the square hole drill bit for operation, because the difficulty of drilling a square hole with the drill bit is greater than that of drilling a round hole, and the existing electric drill generally uses a single motor and a single The shaft outputs the power. Therefore, in the case that it is difficult to drill the square hole itself, and the output power is too strong, the square hole drill bit is very easy to break during the drilling process.

Abstract

The invention belongs to the field of small electronic equipment, and particularly relates to a small square hole electric drill. The small square hole electric drill comprises an electric drill body,wherein an end head is arranged at the front end of the electric drill body; a drilling assembly for drilling a square hole is installed at the front end of the end head; a driving assembly is arranged inside the electric drill body; the driving assembly drives the drilling assembly to operate; and then the square hole is drilled in a workpiece to be machined. The small square hole electric drillhas the following advantages that 1, the drilling assembly with the special structural design limits the movement range of a square hole drill bit through an arranged limiting frame, so that the square hole drill bit is not prone to position deviation and is not prone to breakage in the drilling process; and 2, the arranged driving assembly outputs the power of a motor through the combined actionof two different rotating shafts, compared with a traditional electric drill adopting a single motor and a single shaft to output power, the driving assembly with the structural design can ensure that the output power is not too high while the drilling operation is guaranteed, and the situation that the workpiece is damaged due to the fact that the drill bit which is operated strongly is caused by misoperation in the drilling operation is avoided.

Description

technical field [0001] The invention relates to the field of small electronic equipment, in particular to a small electric drill with square holes. Background technique [0002] An electric drill, as the name suggests, is a mechanical device that uses electrical energy as an energy source for drilling. Electric drill is the most commonly used power tool by people. It has the advantages of convenience, low price, and portability, and is highly praised by workers in the hardware and decoration industries. Electric drills in the prior art can be divided into round-hole electric drills and square-hole electric drills according to different drilling shapes. The biggest difference between round-hole electric drills and square-hole electric drills lies in the difference in drill bits. The operation difficulty of square-hole electric drills is greater than that of round-hole electric drills. homework difficulty. [0003] In the prior art, the square hole electric drill generally a...
