Abstract
The invention relates to an improved electric drill which comprises an electric drill main body and a drill bit mechanism, and is characterized in that the drill bit mechanism comprises clamping teeth, a shrunk clamping block and a shrunk clamping sleeve; the clamping teeth are positioned inside the shrunk clamping sleeve; and the shrunk clamping block is arranged between the clamping teeth and the shrunk clamping sleeve. The improved electric drill has the advantages of simple structure, high practicality, high safety and high working efficiency.
Description
Technical field
The present invention relates to a kind of improved electric drill.
Background technology
Now on the market, diversiform electric drill is very many, and its function and model are all had nothing in common with each other; And the purposes of electric drill also is more and more wider, more and more universal along with electric tool, and the function of electric tool also is more and more complete; And more and more desalinated for the thing of some details; The dismounting of the drill bit mechanism of electric drill all is nerve-wracking thing, not only removes extremely inconveniently, and also needs specific instrument dismounting the time.
Summary of the invention
The purpose of this invention is to provide a kind of improved electric drill.
The technical scheme that the present invention adopts is:
A kind of improved electric drill comprises drill body and drill bit mechanism, it is characterized in that: said drill bit mechanism includes latch, tightens fixture block and tightens cutting ferrule, and said latch is positioned at and tightens cutting ferrule inside, latch and tighten also to be provided with between the cutting ferrule and tighten fixture block.
One side of said latch is provided with the latch boss.
The handle portion of said drill body also is provided with slipmat, and the bottom of said drill bit mechanism is provided with measurement mechanism, and measurement mechanism is connected together through flexibly connecting piece and drill bit mechanism.
Advantage of the present invention is: simple in structure, practical, safe, and high efficiency.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail.
Fig. 1 is a structural representation of the present invention.
Wherein: 1, latch boss, 2, latch, 3, tighten cutting ferrule, 4, tighten fixture block, 5, drill body, 6, flexibly connect piece, 7, slipmat, 8, drill bit mechanism, 9, measurement mechanism.
The specific embodiment
As shown in Figure 1; A kind of improved electric drill comprises drill body 5 and drill bit mechanism, it is characterized in that: said drill bit mechanism 8 includes latch 2, tightens fixture block 4 and tightens cutting ferrule 3; Said latch 2 is positioned at and tightens cutting ferrule 3 inside, latch 2 and tighten also to be provided with between the cutting ferrule 3 and tighten fixture block 4.
One side of said latch is provided with latch boss 1.
The handle portion of said drill body 5 also is provided with slipmat 7, and the bottom of said drill bit mechanism 8 is provided with measurement mechanism 9, and measurement mechanism 9 is connected together with drill bit mechanism 8 through flexibly connecting piece 6.
The present invention is simple in structure understandable; And locking is effective; When tightening when tightening cutting ferrule 3, tighten cutting ferrule 3 and drive and tighten fixture block 4 and drive tightening of latch 2, so just can well pin drill bit; And in boring, just can use measurement mechanism 9 to measure owing to need measure drilling depth sometimes.
