Drill bit device for home and office decoration

Abstract

The invention discloses a drill bit device for home and office decoration. The drill bit device comprises a drill rod; the drill rod comprises a drill stock and a drill bit; one end of the drill stockis fixedly connected with the drill bit, and the outer side of the drill bit is provided with three symmetrical open grooves and further provided with a limiting disc; the right end surface of the limiting disc is fixedly connected with a contact block, and the middle of the limiting disc and the middle of the contact block are both provided with through square openings; the side, away from the drill stock, of the drill bit penetrate through the square openings and stretches to the right sides of the square openings, and the left side of the limiting disc is provided with a fixing mechanism;and the fixing mechanism comprises two fixing hoops, and the two ends of the two fixing hoops are fixedly connected through fixing bolts. The drill bit device can drill square holes, the drilled holesare quite standard without being subjected to repair machining in the later period, meanwhile, the effect that the drill bit is always perpendicular to the wall in the working process can be ensured,the perpendicularity of the drilled holes is ensured, and the drilling efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of home office decoration drilling, in particular to a drill bit device for home office decoration. Background technique [0002] With the increasing scope and quantity of home decoration and company decoration, there are more and more requirements for making square holes. In the current existing market, the drilling is done by hand-held drills, and most of them use round drill bits for drilling. If you want to make a square hole, you need to make four holes first, and then Carry out drilling. Then modify it so that a square hole can be punched. However, as the diameter of the square hole increases, the difficulty of operation increases. operation of this mode. First: a lot of manpower and time are wasted, and it also has a very large impact on the life of the drill bit. Second: After four holes are drilled, the holes are then drilled and modified. Whether such holes can achieve a perfect square is also...
