Abstract

A kind of hole making drill location reaming system, be made up of electric hand drill, hole making drill, fixed arm, spring, motion stops, slipmat, the fixed arm of hollow be installed on the both sides of electric hand drill, in fixed arm, be equipped with spring, outer spring end is equipped with motion stops, and slipmat is equipped with in the outer end of motion stops; Have employed scheme of the present utility model, overcome and need the hole reaming held successfully, because the center of circle cannot be located, the hole making drill that existing diameter is larger cannot use, and by the shortcoming of manhole hole milling inefficiency, is particularly suitable for small sircle hole and changes big hole.

Description

A kind of hole making drill location reaming system

Technical field

The utility model relates to the location reaming of a kind of hole making drill, the hole making drill location reaming system that the circular hole in particular for having opened expands again.

Background technology

At present, we need when installing Down lamp to open circular hole on gypsum plaster ceiling board or plank or other materials, every day use many be set up hole making drill (circular with sawtooth) with electric hand drill, hole making drill center has one to locate drill bit, in use, electric hand drill High Rotation Speed drives hole making drill to rotate, the drill bit of hole making drill is aimed at the center of circle needing perforate, with regard to energy perforate, when after holding hole successfully or when needing to install the larger lamp of diameter, need position, the hole reaming held successfully, because the center of circle cannot be located, the hole making drill that existing diameter is larger just cannot use, low again by manhole hole milling efficiency.

Utility model content

In order to overcome hold hole successfully after or need the larger lamp of diameter is installed time, need position, the hole reaming held successfully, because the center of circle cannot be located, the hole making drill that existing diameter is larger cannot use, by the shortcoming that manhole hole milling efficiency is low again, the utility model proposes a kind of hole making drill location reaming system with head it off, its good effect is: have employed a kind of hole making drill location reaming system, can continue in the outside of opening circular hole to expand aperture easily, install to be applicable to larger Down lamp, and substantially increase the efficiency of reaming.

The utility model solves the technical scheme that its technical problem adopts: a kind of hole making drill location of the present utility model reaming system, be made up of electric hand drill, hole making drill, fixed arm, spring, motion stops, slipmat, the fixed arm of hollow is installed on the both sides of electric hand drill, spring is equipped with in fixed arm, outer spring end is equipped with motion stops, and slipmat is equipped with in the outer end of motion stops.

The technical solution adopted in the utility model will coordinate accompanying drawing to elaborate in a particular embodiment.

Accompanying drawing explanation

Here is brief description of drawings.

Fig. 1 is a kind of hole making drill location of the present utility model reaming system structural representation.

1. electric hand drills, 2. hole making drill, 3. fixed arm, 4. spring, 5. motion stops in figure, slipmat.

Detailed description of the invention

In the embodiment in figure 1, we further illustrate the utility model to implement a kind of hole making drill location reaming system:

Fig. 1 is a kind of hole making drill location of the present utility model reaming system schematic diagram, in figure, electric hand drill 1 is exactly the common electric hand drill for holing, hole making drill 2 is typical circular hole making drill, it has multiple diameter specification, fixed arm 3 is pipes, in order to increase counter bore diameter, pipe is curved 90 degree, one end is fixed on electric hand drill 1, spring 4 is installed in the other end, it is motion stops 5 outside spring 4, motion stops 5 is more smaller than diameter empty in fixed arm 3, can slide, motion stops 5 can be metal, also can be plastics, slipmat 6 is equipped with in the outer end of motion stops 5, it can be one piece of circular rubber blanket, play the effect increasing frictional force.

In use, open electric hand drill switch, the hole making drill High Rotation Speed larger than hole diameter, roughly after contraposition, slipmat 6 outside motion stops 5 in the fixed arm of electric hand drill 1 both sides is pressed on plasterboard or plank, because slipmat 6 and plasterboard or plank exist larger frictional force, there is the effect of spring 4, when advancing hole making drill 2, because pressure increases, frictional force is increasing, even if hole making drill is fixed without the center of circle, also perfect can output the new bore position larger than original room diameter.

Claims

1. a hole making drill location reaming system, be made up of electric hand drill (1), hole making drill (2), fixed arm (3), spring (4), motion stops (5), slipmat (6), it is characterized in that: the fixed arm (3) being provided with hollow on the both sides of electric hand drill (1), fixed arm is equipped with spring in (3), outer spring end is equipped with motion stops (5), and slipmat (6) is equipped with in the outer end of motion stops (5).
