Description
Technical field
The invention belongs to field of power tools, and in particular to a kind of electric drill.
Background technology
Electric drill is the most-often used electric tool of people, and that it has the advantages that is convenient, inexpensive, is easy to carry, depth by hardware,
The favorable comment of worker in industry of decorateing.But operator is frequently necessary to more bit change when using electric drill, because seeking conveniently, operation
Person is the direct more bit change in the case where electric drill does not power off, if oneself or other people have touched switch in more bit change by mistake
Moved so that drill bit bores, be extremely dangerous.
The content of the invention
For deficiency of the prior art, the present invention provides a kind of electric drill.
The present invention is achieved through the following technical solutions.A kind of Household electric drill, including electric drill body and for installing drill bit
Drill chuck, the drill chuck is interior to be provided with a ring annular groove, is provided with slide bar in the annular groove, the end of described slide bar one end extends
In the keyhole of drill chuck, the part that the slide bar stretches into keyhole is inclined-plane, and the drill chuck exterior measuring is provided with a ring shape shelves
Wall, the annular shelves wall are fixed on electric drill body, and the annular shelves wall is provided with an opening, is provided with the electric drill body
One passage, the passage is interior to be provided with air bag, and the other end of the slide bar extends in electric drill body and leans the one of air bag
End, the other end of the air bag are provided with pad, and the top of the pad is provided with back-moving spring, and the side of the pad is provided with electricity
Switch is bored, the opposite side of the pad is provided with electric drill button, and the pad is provided with two projections, and the electric drill button is provided with
Two coordinate with projection groove, more bit change when operator electric drill key insertion keyhole is leaned the inclined-plane on slide bar and caused
For slide bar toward moving in electric drill body, one end of the slide bar extruding gasbag causes the pad on the air bag other end to rise until pad
On projection be moved to groove location, at this moment operator press electric drill button, projection insertion groove in, pad touches to be opened less than electric drill
Close, electric drill key is extracted after operator finishes changing drill bit, pad moves down extruding gasbag, projection in the presence of back-moving spring
Stagger with groove, air bag pushes back one end of slide bar in keyhole.
Further, the projection is distributed in the both ends of pad.
Further, the contact surface of the slide bar and annular groove is provided with a circle ball.
Further, the drill chuck is provided with an index line.
Compared with prior art, in more bit change in the case of energization, operator needs first on annular groove the present invention
Electric drill key, is then inserted keyhole by opening alignment keyhole, and the inclined-plane that electric drill key is leaned on slide bar causes slide bar toward electricity
Bore and moved in body, one end of slide bar movement extruding gasbag causes the pad on the air bag other end to rise until the projection on pad
Groove location being moved to, at this moment operator presses electric drill button, and projection is inserted in groove so that pad is touched less than drill switch,
Electric drill key is extracted after operator finishes changing drill bit, pad moves down extruding gasbag in the presence of back-moving spring, projection with
Groove staggers, and air bag pushes back one end of slide bar in keyhole, and at this moment operator presses electric drill button, and electric drill button promotes pad
Touch drill switch, electric drill normal work.After said structure, even if operator changes in the case where electric drill does not power off
Drill bit will not also cause danger.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Structural representation when Fig. 2 is more bit change of the invention.
Embodiment
Below in conjunction with the accompanying drawings with embodiment, the invention will be further described.As shown in Figure 1 to Figure 2, Yi Zhongjia
With electric drill, including electric drill body 1 and the drill chuck 2 for installing drill bit, the drill chuck 2 is interior to be provided with a ring annular groove 22, institute
State in annular groove 22 and be provided with slide bar 3, the end of described one end of slide bar 3 is extended in the keyhole 21 of drill chuck 2, and the slide bar 3 is stretched
The part for entering keyhole 21 is inclined-plane, and the exterior measuring of drill chuck 2 is provided with a ring shape shelves wall 4, and the annular shelves wall 4 is fixed on electricity
Bore on body 1, the annular shelves wall 4 is provided with an opening 41, and a passage 5, the passage are provided with the electric drill body 1
Air bag 6 is provided with 5, the other end of the slide bar 3 extends in electric drill body 1 and leans one end of air bag 6, the air bag 6
The other end be provided with pad 10, the top of the pad 10 is provided with back-moving spring 8, and the side of the pad 10 is opened provided with electric drill
11 are closed, the drill switch 11 selects snap switch, and the opposite side of the pad 10 is provided with electric drill button 9, on the pad 10
Provided with two projections 101, the electric drill button 9 is provided with two grooves 91 coordinated with projection 101.
The projection 101 is distributed in the both ends of pad 10 so that operator press electric drill button 9 when pad 10 uniformly by
Power.
The contact surface of the slide bar 3 and annular groove 22 is provided with a circle ball, reduces slide bar 3 and ring when drill chuck 2 rotates
Frictional force between shape groove 22.
The drill chuck 2 is provided with an index line, when index line alignment opening 41, the alignment keyhole 21 of opening 41.
As long as operator presses electric drill button to the present invention under normal circumstances, electric drill button promotes pad to lean drill switch
Electric drill begins to move afterwards；The opening on annular groove is first directed at keyhole by operator during more bit change, then electric drill key
100 insertion keyholes, electric drill key leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, slide bar movement extruding gas
One end of capsule causes the pad on the air bag other end to rise until the projection on pad is moved to groove location, and at this moment operator presses
Piezoelectricity bores button, and projection is inserted in groove, and pad is touched less than drill switch, and electric drill key is extracted after operator finishes changing drill bit
100, pad moves down extruding gasbag in the presence of back-moving spring, and projection staggers with groove, and air bag pushes away one end of slide bar
Return in keyhole, at this moment operator presses electric drill button, and electric drill button promotes pad touching drill switch, electric drill normal work.
After said structure, even if operator, in the case where electric drill does not power off, more bit change will not also cause danger.
