Abstract
The utility model relates to a multifunctional drill which belongs to an electric drill accessory and comprises a starting drill (1), a jig drill (2) and a spacing ring (3), wherein the starting drill (1) comprises a front cutting part (11) and a rear connecting part (12), and the axial center of the starting drill is provided with a through hole (13); the rear half part of the jig drill can be axially moved to be arranged in the through hole; and the spacing ring can be coaxially moved to be sheathed on the periphery wall of the connecting part of the starting drill, thus the structure not only can drill two-stage holes of different sizes and cause a screwhead to sink into the large hole, but also can adjust the drilling depth in the light of the actual situation.
Description
Technical field
The utility model relates to the accessory of electric drill, particularly a kind of multi-functional drill bit.
Background technology
Generally all be to adopt screw to do connector (screw is made up of shank of screw and the head of screw on it) when we are fixed together two members, such as being installed, a lot of products of using in ceiling, door lock and the daily life etc. all can use screw, before twisting screw, bore a pilot hole with electric drill earlier usually, but, on the general electric drill one-level drill bit can only be installed, also just can only get out a pilot hole, like this, after screw is screwed on, its head of screw also can be exposed at the outer surface of connector, both easily the people was caused injury, not attractive in appearance yet; If need head of screw also is screwed into component inside, have only the drill bit that varies in size by replacing to realize this purpose, thus, not only can increase the people's work amount, and may influence the concentricity of perforate, and make that the installation of screw is very inconvenient, cause the connection of two members also not firm.
The utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of not only can get out the two-stage hole that varies in size, and can regulate the multi-functional drill bit of drilling depth.
To achieve these goals, the technical scheme that the utility model adopted is as follows: a kind of multi-functional drill bit, comprise starting drill, jig drill head and spacing ring, starting drill comprises the anterior cutting tip and the coupling part at rear portion, the axial centre of described starting drill is provided with a through hole, the latter half of of jig drill head can axially movablely be installed in the through hole, and spacing ring can axially movablely be sheathed on the periphery wall of coupling part at starting drill rear portion.
The utility model also has following attached technical characterictic:
The coupling part at starting drill rear portion is provided with a screwed hole that communicates with through hole, is provided with a clamping screw that matches with it in this screwed hole; The perisporium of spacing ring is provided with another screwed hole, is provided with another clamping screw that matches with it in this another screwed hole.
The perisporium of spacing ring also is provided with a groove, and described clamping screw is arranged in the groove, and the length of clamping screw is greater than the degree of depth of screwed hole.
Relative prior art, the beneficial effects of the utility model are: the axial centre of described starting drill is provided with a through hole, the latter half of of jig drill head can axially movablely be installed in the through hole, spacing ring can axially movablely be sheathed on the periphery wall of coupling part at starting drill rear portion, therefore, this structure not only can get out the two-stage hole that varies in size, and can regulate the degree of depth of boring according to actual conditions.

Fig. 2 is the utility model structural representation;
Fig. 3 is the upward view of Fig. 2;
Fig. 4 is the structural representation of drill bit among Fig. 2;
Fig. 5 is the structural representation of spacing ring among Fig. 2.
The specific embodiment
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments:
Extremely shown in Figure 5 as Fig. 1, a kind of preferred embodiment that provides for the utility model, a kind of multi-functional drill bit, comprise that a front portion is that cutting tip 11 and rear portion are the starting drill 1 of coupling part 12, coupling part 12 is clamped in the clamp 41 of electric drill 4 front ends, the axial centre of described starting drill is provided with a through hole 13, in this through hole a jig drill head 2 can axially movablely be installed, the cutting tip 20 of this jig drill head is exposed to the front end of starting drill, and the coupling part 12 at starting drill 1 rear portion is provided with a screwed hole 14 that communicates with through hole 13, be provided with a clamping screw that matches with it 15 in this screwed hole, therefore, can screw clamping screw 15 then according to the distance between the tip of the tip of length adjustment jig drill head 2 cutting tips 20 of shank of screw and starting drill cutting tip 11, just can tighten the jig drill head.
Described spacing ring 3 can axially movablely be sheathed on the periphery wall of coupling part 12 at starting drill 1 rear portion, and the perisporium of spacing ring 3 is provided with another screwed hole 31, is provided with another clamping screw 32 that matches with it in this another screwed hole.Can adjust the tip of starting drill 1 cutting tip 11 and the distance between the spacing ring 3 according to the thickness of head of screw.
As mentioned above, disposable two the different holes of diameter that just can get out after starting drill 1 and jig drill head 2 are assembled into one, guaranteed the concentricity in two holes, wherein the aperture that gets out of jig drill head 2 can be made the pilot hole of shank of screw, and head of screw just can be trapped in the macropore that starting drill 1 gets out (described starting drill 1 and jig drill head 2 have the model that varies in size).Therefore, make the screw of being installed neither can cause injury to the people, also seem very attractive in appearance, also reduced the people's work amount simultaneously, it is very convenient and firm that this operation makes that also two members are installed.Simultaneously, described spacing ring 3 also can prevent excessively piercing of starting drill 1, makes that the macropore that is bored is dark excessively.
In addition, the perisporium of spacing ring 3 also is provided with a groove 33, and described clamping screw 15 is arranged in the groove, and the length of clamping screw grows part and places groove greater than the degree of depth of screwed hole 14.This structure can prevent that spacing ring 3 from because of not tightening the phenomenon of slippage, having improved safety coefficient greatly.
