Abstract
The utility model relates to a metal hole digger with adjustable, its constitution includes: track plate, drill bit, cutting head, rotation axis, its characterized in that: be equipped with the cutting head attachment rail of four symmetries on the track plate, the cutting head passes through the nut to be fixed on the track, is equipped with the scale on the track, and the radius of definite trompil that can be accurate is big or small, the center pin lower extreme is installed to drill bit upper end, and center pin lower extreme beginning screw hole inserts back in the center pin with the drill bit, and it is fixed with the drill bit to pass the screw hole with the screw. The utility model discloses the drill bit is convenient to be dismantled, has avoided the drill bit to damage and has leaded to later the unable problem of using of whole hole digger, and this hole digger trompil radius is adjustable simultaneously, and application scope is wide, sets up four attachment rails simultaneously, can be according to specific cut material's the condition, the required quantity of adjustment cutting head when the use.
Description
Technical field
This utility model relates to a kind of hole making drill, particularly relates to a kind of adjustable metal hole making drill.
Background technology
Hole making drill is arranged on common electric drill, just can carry out any cutting of circular hole, square hole, delthyrium, straight line, curve easily on the arbitrary surfaces such as the plane of the various sheet material such as copper, ferrum, rustless steel, lucite, sphere.Flexibly, conveniently, safety, of many uses.
But existing hole making drill specification is too much, is meeting different materials, during bore size difference, it is necessary to use different hole making drills, such complex operation, and in a porous construction, it is necessary to use hole making drill too much；Meanwhile, when the drill bit of hole making drill or cutting head are damaged, whole hole making drill just cannot use, and causes great waste.
Summary of the invention
The purpose of this utility model is in that for deficiency of the prior art, and provides a kind of adjustable metal hole making drill.
The technical scheme that this utility model adopts:
A kind of adjustable metal hole making drill, its composition includes: rotating shaft, rotating shaft is fixed on track plate center, and drill bit is inserted in rotating shaft, is provided with cutting head on track plate, rotating shaft end is fixing with track plate to be connected, rotating shaft end has the screw hole corresponding with drill bit along axis, and drill bit inserts in screw hole, is fixed by screw, having four symmetrical attachment rails on track plate, cutting head is fixed on the optional position of attachment rail by nut.
Described adjustable metal hole making drill, place vertical with axis, rotating shaft lower end is provided with screwed hole, and screwed hole end is corresponding with screw hole end.
Described adjustable metal hole making drill, cutting head end is provided with screw thread, is fixed on four attachment rails of track plate by nut, and four attachment rail edges are carved with scale.
Adjustable metal hole making drill described in the utility model, has the following characteristics that
1, this utility model adopts removable drill bit, it is to avoid when damaging occurs in drill bit, the phenomenon that whole hole making drill cannot use, simultaneously can the different material of perforate as required, carry out the type of more bit change, it is achieved that multi-use；
2, this utility model adopts removable cutting head, equally possible when damaging occurs in cutting head, and changes timely；
3, in use, according to the size of perforate, the installation site needing cutting head can be set, a cutting head can be set, it is possible to multiple cutting head is set, conveniently change timely according to field condition, use more variation.

Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of track plate.
In figure: 1, rotating shaft；2, screw hole；3, track plate；4, drill bit；5, cutting head；6, nut；7, screw；8；Screwed hole；9, attachment rail；10, scale.
Detailed description of the invention
A kind of adjustable metal hole making drill, its composition includes: rotating shaft 1, rotating shaft 1 is fixed on track plate 3 center, and drill bit 4 is inserted in rotating shaft 1, is provided with cutting head 5 on track plate 3, rotating shaft 1 end is fixing with track plate 3 to be connected, rotating shaft 1 end has the screw hole 2 corresponding with drill bit 4 along axis, and drill bit 4 inserts in screw hole 2, is fixed by screw 7, having four symmetrical attachment rails 9 on track plate 3, cutting head 5 is fixed on the optional position of attachment rail 9 by nut 6.
Described adjustable metal hole making drill, place vertical with axis, rotating shaft 1 lower end is provided with screwed hole 8, and screwed hole 8 end is corresponding with screw hole 2 end.
Described adjustable metal hole making drill, cutting head 5 end is provided with screw thread, is fixed on four attachment rails 9 of track plate 3 by nut 6, and four attachment rail 9 edges are carved with scale 10.
When hole making drill is operated, sets drill bit according to the size of perforate and position in orbit is installed, drill bit is inserted in the screw hole in rotating shaft, then make to be screwed, fix drill bit with nut afterwards and can carry out operation.
Preferred embodiment of the present utility model described in detail above.Should be appreciated that the ordinary skill of this area just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art pass through the available technical scheme of logical analysis, reasoning, or a limited experiment on the basis of existing technology according to design of the present utility model, all should in the protection domain being defined in the patent claims.
