The utility model discloses simple structure, convenient to use adopts split type structure, can realize that a location drill bit is equipped with the effect of several aperture disc, can reduce cost of manufacture and use cost effectively, and the trompil is fast, and the trompil high quality is low to workman's technical requirement, reaches the effect that saves labour, saves time, provides the support for the plastics drainage inspection shaft of building trade punches.
Description
Technical field
The utility model belongs to building field, relates to a kind of hole making drill, specifically a kind of split type hole making drill.
Background technology
The plastic drainage inspection well that building trade adopts belongs to half-finished material, access arm, be in charge of time need perforate on a corresponding position just can carry out follow-up adapter work.Mostly traditional plastic drainage inspection well perforate is to adopt the perforate of electric saw cutter.Traditional perforate mode is adopted to there is following problem:
1, carry out perforate after shape can only being drawn on pit shaft, artificial draw circle and perforate easily there is error and depart from, perforate speed is slow.
2, when perforate, will stare at the shape marked the moment, and sawdust powder easily obstructs the view while perforate, cause perforate speed slow, perforate is inaccurate, easily that hole saw is large.
3, when when a large amount of perforate, easily there is fatigue, hand acid phenomenon in people, easily drifts out hole site.
4, bore size becomes large or to diminish and perforate departs from inaccurate meeting and causes when accessing arm and being in charge of, arm (being in charge of) and pit shaft there will be a large amount of space, need the amount of repairing more, the excessive severe patient in space while requiring (cannot meet seepage) can cause pit shaft to be scrapped.
At present, people are according to perforate demand specialized designs integral type hole making drill, be made up of location drill bit, apertured disc, connector, take electric hand drill as power, can realize quick perforate, but hole making drill adopts integral structure, cost of manufacture is high, and require to be equipped with corresponding hole making drill for different apertures, add use cost.
Utility model content
The purpose of this utility model provides a kind of split type hole making drill, adopt split-type structural, the effect that a location drill bit is equipped with several apertured disc can be realized, can effectively reduce cost of manufacture and use cost, for the plastic drainage inspection well punching of building trade provides support.
The technical scheme that the utility model adopts:
A kind of split type hole making drill, comprise location drill bit, apertured disc, described location drill bit is made up of bit head, threaded portion and connecting portion, between threaded portion and connecting portion, arrange snap ring; The periphery of described apertured disc arranges serrated knife, and the bottom centre of apertured disc arranges nut, and the screw thread of nut matches with the screw thread of the threaded portion of location drill bit.During perforate, the connecting portion of location drill bit is connected on electric hand drill, then the threaded portion of the nut precession of apertured disc location drill bit, screw under the stop of snap ring (drill bit run direction contrary with the direction of nut screwing clamping, make drill bit when rotating, apertured disc can not be made to loosen), bit head is aimed at the centre point marked, starting electric hand drill makes drill bit pierce in plastic drainage inspection well, drives apertured disc to rotate and carry out perforate to plastic drainage inspection well while the bit of location.
The threaded portion external diameter of described location drill bit is greater than bit head external diameter.
The utility model structure is simple, easy to use, adopt split-type structural, can realize the effect that a location drill bit is equipped with several apertured disc, can effectively reduce cost of manufacture and use cost, perforate speed is fast, perforate quality is high, low to the technical requirement of workman, reach saving of labor, timesaving effect, for the plastic drainage inspection well punching of building trade provides support.

Fig. 2 is the structural representation of apertured disc of the present utility model.
Fig. 3 is the utility model using state reference diagram.
In figure: 1, bit head; 2, threaded portion; 3, snap ring; 4, connecting portion; 5, serrated knife; 6, nut; 7, electric hand drill.
Detailed description of the invention
Below by embodiment the utility model is described in further detail by reference to the accompanying drawings, but not as to restriction of the present utility model.
Split type hole making drill provided by the utility model comprises location drill bit, apertured disc.
As shown in Figure 1, location drill bit is made up of bit head 1, threaded portion 2 and connecting portion 4, and wherein threaded portion 2 external diameter is greater than bit head 1 external diameter, arranges snap ring 3 between threaded portion and connecting portion.
As shown in Figure 2, apertured disc diameter specifications can set according to bore size, the periphery of apertured disc arranges serrated knife 5, for sawing plastic well, bottom centre's welded nut 6 of apertured disc, the centre point of nut is consistent with electric drill centre point, and the screw thread of nut matches with the screw thread of the threaded portion of location drill bit.
During perforate, as shown in Figure 3, the connecting portion 4 of location drill bit is connected on electric hand drill 7, then the threaded portion 2 of nut 6 precession of apertured disc location drill bit, screw under the stop of snap ring 3 (drill bit run direction contrary with the direction of nut screwing clamping, making drill bit when rotating, apertured disc can not be made to loosen).Bit head 1 is aimed at the centre point marked, start electric hand drill 7 and make drill bit pierce in plastic drainage inspection well, drive apertured disc to rotate while the bit of location and perforate is carried out to plastic drainage inspection well.The degree of depth that drill bit stretches into can not be rocked with disk during perforate, for different adapter bores, can be the apertured disc that each location drill bit is equipped with multiple different bore accordingly.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
