Abstract
A kind of multiple-drilling machine expansion drill bit, including mounting rack and drive rod, mounting rack is equipped with the first transmission gear, the second transmission gear and third transmission gear, first transmission gear and the second transmission gear engaged transmission, second transmission gear and third transmission gear engaged transmission, the both ends of first transmission gear, the second transmission gear and third transmission gear are equipped with clamping interface, one end of drive rod is connected in the clamping interface of any one transmission gear, and the other end of drive rod is connected on the interface of drilling machine.The utility model provides a kind of multiple-drilling machine expansion drill bit, three drill bits can be driven to drill simultaneously by a drilling machine, can both install the identical drill bit of bit diameter, and the right side can install the different drill bit of bit diameter and carry out bore operation；It is additionally provided with handle on mounting rack, facilitates operator to stablize and expands drill bit, compared with the existing drilling machine that a drill bit can only be used to drill, greatly improves the working efficiency of drilling.
Description
Technical field
The utility model relates to a kind of multiple-drilling machine expansion drill bits.
Background technique
Electric drill is a kind of drilling machine that power is done using electricity.Currently, existing electric drill can only use a drill bit to carry out
Bore operation needs just to need replacing drill bit when the drill bit of other diameters.When needing using a kind of drill bit of diameter in other objects
When boring multiple holes on body, can only one hole in a hole brill, working efficiency is lower.
Utility model content
The utility model provides a kind of multiple-drilling machine expansion drill bit, can drive three drill bits simultaneously by a drilling machine
It drills, the identical drill bit of bit diameter can be both installed, the right side can install the different drill bit of bit diameter and carry out drilling work
Industry；It is additionally provided with handle on mounting rack, facilitates operator to stablize and expands drill bit, a drill bit can only be used to be bored with existing
The drilling machine in hole is compared, and the working efficiency of drilling is greatly improved.
In order to solve the above technical problems, technical solution used by the utility model is as follows:
With expanding drill bit, including mounting rack and drive rod, mounting rack is equipped with the first transmission gear, for a kind of multiple-drilling machine
Two transmission gears and third transmission gear, the first transmission gear and the second transmission gear engaged transmission, the second transmission gear and the
Three transmission gears engaged transmission, the both ends of the first transmission gear, the second transmission gear and third transmission gear are equipped with clamping and connect
Mouthful, one end of drive rod is connected in the clamping interface of any one transmission gear, and the other end of drive rod is connected to drilling machine
On interface, handle is additionally provided on mounting rack.
There are two the handle is set.
By adopting the above technical scheme, the utility model has the following beneficial effects:
Expansion drill bit in the utility model can drive three drill bits to drill simultaneously by a drilling machine, both may be used
To install the identical drill bit of bit diameter, the right side can install the different drill bit of bit diameter and carry out bore operation；On mounting rack also
Equipped with handle, facilitates operator to stablize and expand drill bit, compared with the existing drilling machine that a drill bit can only be used to drill,
Greatly improve the working efficiency of drilling.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Mounting rack 1, drive rod 2, the first transmission gear 3, the second transmission gear 4, third transmission gear 5, handle 6, drilling machine
7, drill bit 8.
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of multiple-drilling machine is with expanding drill bit, including mounting rack 1 and drive rod 2, mounting rack 1 is equipped with the
One transmission gear 3, the second transmission gear 4 and third transmission gear 5, the first transmission gear 3 engage biography with the second transmission gear 4
It is dynamic, 5 engaged transmission of the second transmission gear 4 and third transmission gear, the first transmission gear 3, the second transmission gear 4 and third transmission
The both ends of gear 5 are equipped with clamping interface, and one end of drive rod 2 is connected in the clamping interface of any one transmission gear, pass
The other end of lever 2 is connected on the interface of drilling machine, and handle 6 is additionally provided on mounting rack 1.
There are two the handle 6 is set.
Expansion drill bit in the utility model can drive three drill bits 8 to drill simultaneously, both by a drilling machine 7
The identical drill bit 8 of 8 diameter of drill bit can be installed, the right side can install the different drill bit 8 of 8 diameter of drill bit and carry out bore operation；Installation
It is additionally provided with handle 6 on frame 1, facilitates operator to stablize and expands drill bit, a drill bit can only be used to drill with existing
Drilling machine 7 is compared, and the working efficiency of drilling is greatly improved.
The present embodiment not makes any form of restriction the shape of the utility model, material, structure etc., all foundations
The technical essence of the utility model any simple modification, equivalent change and modification to the above embodiments, belong to this reality
With the protection scope of new technique scheme.
