Abstract
The utility model provides a drill bit of adjustable diameter size, including the drill bit body, the drill bit body includes drilling rod, rotary disk and chuck, the drilling rod passes through the rotating member and installs on the rotary disk, the chuck sets up the rear side at the rotary disk, the outside side of chuck is equipped with locating hole and concave groove, be equipped with the connecting piece in the concave groove, the adjustable trestle passes through the connecting piece to be installed on the chuck, this drill bit of adjustable diameter size reasonable in design, and working range is wide, and labour saving and time saving.
Description
Technical field
The utility model is the drill bit of adjustable diameter, belongs to mechanical equipment technical field.
Background technology
The application of drill bit is ubiquitous, can quickly realize drilling through work by drill bit, but the drill bit using on the market now is mostly fixed design, operating personnel are in use, the characteristic according to rapidoprint is needed to select the size of drill bit, therefore it is accomplished by when drilling through work, continuous more bit change, therefore more waste time and energy, and when processing, need aside to place the drill bit of plurality of specifications size, in use, carrying out at any time is changed, and not only carries inconvenience, and adds acquisition cost.
Utility model content
The deficiency existing for prior art, the utility model purpose is to provide the drill bit of adjustable diameter, and to solve the problem proposing in above-mentioned background technology, the utility model is reasonable in design, and working range is wide, and time saving and energy saving.
To achieve these goals, the utility model is to realize by the following technical solutions: the drill bit of adjustable diameter, including drill body, described drill body includes drilling rod, rotating disk and chuck, described drilling rod is installed on the rotating pan by revolving part, and described chuck is arranged on the rear side of rotating disk, and the outer avris of described chuck is provided with positioning hole and concave groove, being provided with connector in described concave groove, adjustable trestle is arranged on chuck by connector.
Further, the quantity of described adjustable trestle is 3.
Further, described adjustable trestle is additionally provided with screw.
The beneficial effects of the utility model: the drill bit of adjustable diameter of the present utility model, including adjustable trestle, connector, chuck, rotating disk, revolving part, drill body and positioning hole；
1. manually rotary chuck, can adjust the position of adjustable trestle, therefore, it is possible to adjust the diameter of drill body, thus avoids when drilling through work more bit change back and forth, and reasonable in design, working range is wide；
2. the drill bit of this adjustable diameter is novel in design, and operating efficiency is high, and more time saving and energy saving.
Brief description
Fig. 1 is the structural representation of the drill bit of the utility model adjustable diameter；
Fig. 2 be the utility model adjustable diameter drill bit in the structural representation of adjustable trestle；
In figure: 1-drilling rod, 2-revolving part, 3-rotating disk, 4-chuck, 5-positioning hole, 6-connector, 7-concave groove, 8-adjustable trestle.
Detailed description of the invention
For make the utility model realize technological means, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, the utility model is expanded on further.
Refer to Fig. 1 to Fig. 2, a kind of technical scheme of the utility model offer: the drill bit of adjustable diameter, including drill body, described drill body includes drilling rod the 1st, rotating disk 3 and chuck 4, described drilling rod 1 is arranged in rotating disk 3 by revolving part 2, and described chuck 4 is arranged on the rear side of rotating disk 3, and the outer avris of described chuck 4 is provided with positioning hole 5 and concave groove 7, being provided with connector 6 in described concave groove 7, adjustable trestle 8 is arranged on chuck 4 by connector 6.
The quantity of adjustable trestle 8 is 3, it is additionally provided with screw on adjustable trestle 8, in use, need to arrange the diameter of drill body according to different processing raw material, operating personnel can carry out manual rotation chuck 4, it is thus possible to the connector 6 in driving concave groove 7 stretches, adjustable trestle 8 can be driven while flexible to carry out freely stretching, thus have adjusted the support scope of adjustable trestle 8, and then increase the diameter of drill body, reasonable in design, increase the working range of drill body, and then avoid the drill bit changing different size back and forth, therefore more time saving and energy saving, operating efficiency is higher.
Of the present utility model general principle and principal character and of the present utility model advantage have more than been shown and described, to those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, the utility model can be realized in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that include all changes falling in the implication of equivalency and scope of claim in the utility model.Any reference in claim should be considered as limiting involved claim.
In addition, should be understood, although this specification is been described by according to embodiment, but not each embodiment only comprises an independent technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should be using specification as an entirety, and the technical scheme in each embodiment also can form, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that.
