Description

Novel fixed-point hole drill

Technical Field

The utility model relates to a novel fixed-point hole drill.

Background

The perforating drill bit is also called as a perforating saw or a hole saw, and refers to a sawing special circular saw for processing circular holes in modern industry or engineering, and the perforating drill bit is simple and flexible to operate, convenient to carry, safe to use and wide in application. The perforating drill bit is arranged on a common electric drill, so that the perforating cutting of holes such as round holes can be conveniently performed on any curved surfaces such as planes, spherical surfaces and the like of various plates such as copper, iron, stainless steel, organic glass and the like.

And because it is the trompil effect that carries out, unlike with traditional drill bit, its drilling diameter is great, is simultaneously to a slice region drilling, because just begin the drilling like this, frictional force is great, appears drilling error extremely easily like this, and current trompil bores and can set up a drill bit in drilling central point put, carries out the location drilling earlier through the drill bit and carries out accurate location drilling later, however above-mentioned drill bit, has some defects when drilling: 1. the whole needs to overcome the defect that two drill bits are required to drill, so that the consumption is high, and the inner drill bit does idle work all the time except for the initial positioning function; 2. when the whole drill bit is drilled, the inner drill bit can damage the drill core drilled by the outer drill bit, so that the outer drill bit is extruded from the inside, the inner wall of the outer drill bit can be damaged after long-time use, the whole service life is reduced, and therefore, the drilling drill with the accurate positioning and long service life is needed.

Disclosure of Invention

The utility model aims to provide a novel fixed-point hole drill so as to solve the problems in the prior art.

In order to solve the technical problems, the utility model provides the following technical scheme: the rotary drill comprises a drill body, wherein a connecting disc capable of moving up and down along the direction of the drill body is arranged on the surface of the drill body, a rotary disc capable of rotating by taking the connecting disc as a circle center is arranged on the connecting disc, and friction blocks are arranged on the lower surface of the rotary disc in a circumferential array.
