Multi-drill-bit electric drill with air blowing function

Abstract

The invention discloses a multi-bit electric drill with blowing function, comprising: an electric drill main body, a movable disk, a fixed disk and a plurality of drill disks; The drill disc is set between the movable disc and the fixed disc; each drill disc is rotatably connected with the fixed disc through its own rotating shaft, and each drill disc has three slide grooves evenly distributed; The number of discs is equal and the corresponding chute toggle rod; each chute toggle rod can be matched with the chute on the corresponding drill disc, which can drive the drill disc to rotate, and each chute toggle rod on the movable disc A fan plate is arranged in the direction connected with the rotation center of the movable disk, and rotates simultaneously with the movable disk. The multi-drill electric drill with air blowing function of the present invention has multiple drill bits, can complete the drilling work of multiple drill bits at the same time, greatly improves the work efficiency, and can ensure the same depth and size of the drilled holes, and has a good heat dissipation effect.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a multi-bit electric drill with a blower function. Background technique [0002] An electric drill refers to a drilling tool that uses electricity as power. It is a conventional product in electric tools, and it is also the most demanded electric tool product in the market. Electric drills can be used in construction, decoration, household, medical and other occasions, and can be used to scrape the surface of objects or penetrate objects. Usually, when working manually, the use of electric hand drills is often used in small-scale drilling operations on parts. [0003] For example, the Chinese invention patent CN 105436565 A discloses a hand-held electric drill, which includes an electric drill body and a drill chuck for installing the drill bit. A ring-shaped groove is arranged in the drill chuck, and a slide bar is arranged in the ring-shaped groove. The end of one end ...

Problems solved by technology

In the prior art, on the one hand, the layout of the electric drill is unreasonable, and the coordination between the heat dissipation holes and the brushed motor is not good, so that the excess heat inside the electric drill cannot be dissipated, especially the motor is prone to overheating, which is easy to burn out parts and affect The service life of the electric drill; on the other hand, the general manual electric drill operation relies on visual inspection and drilling based on experience, which makes it very difficult to manually control the depth and size of the hand electric drill to keep the depth of the hole consistent with the drilling depth, so the work often occurs. The depth and size of the hole and the phenomenon of different drilling depths
