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, be easy to carry, depth by hardware,
The favorable comment of workman 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 is not powered off, if oneself or other people have touched switch in more bit change by mistake
So that drill bit bores dynamic, it is 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.Household electric drill, including electric drill body and the drill point for installing drill bit
It is provided with head, the drill chuck in a ring annular groove, the annular groove and is provided with slide bar, the end of described slide bar one end extends drill point
In the keyhole of head, the part that the slide bar stretches into keyhole is provided with a ring shape shelves wall, institute on the outside of inclined-plane, the drill chuck
State annular shelves wall to be fixed on electric drill body, the annular shelves wall is provided with an opening, and the electric drill body is interior to be provided with one
Air bag is provided with passage, the passage, the other end of the slide bar extends in electric drill body and leans one end of air bag, institute
The other end for stating air bag is provided with gag lever post, is electric drill button above the gag lever post, and the electric drill button is provided with spacing
Groove, the side of the electric drill button is switched provided with electric drill, and electric drill key insertion keyhole is leaned cunning by operator during more bit change
Inclined-plane on bar causes slide bar toward moving in electric drill body, and one end of slide bar extruding gasbag causes the gag lever post on the air bag other end
Rise until in gag lever post insertion stopper slot, at this moment electric drill button is limited bar and blocks and can not press, when operator finishes changing brill
Electric drill key is extracted after head, gag lever post is pressed down against air bag one end under gravity, and gag lever post departs from stopper slot, air bag
The other end pushes back one end of slide bar in keyhole.
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 instruction line.
Compared with prior art, the present invention is in more bit change in the case of energization, and operator is needed first on annular groove
Electric drill key, is then inserted keyhole by opening alignment keyhole, and electric drill key leans the inclined-plane on slide bar so that the past electricity of slide bar
Bore and moved in body, one end of slide bar extruding gasbag causes the gag lever post on the air bag other end to rise until gag lever post inserts spacing
In groove, at this moment electric drill button is limited bar and blocks and can not press, and electric drill key, gag lever post are extracted after operator finishes changing drill bit
Air bag one end is pressed down against under gravity, and gag lever post departs from stopper slot, and the other end of air bag pushes back one end of slide bar
In keyhole, at this moment operator's pressing electric drill button, electric drill button touching electric drill switch, electric drill normal work.Using above-mentioned knot
After structure, even if operator, in the case where electric drill is not powered off, more bit change 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, household electric
Bore, 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, the ring
Slide bar 3 is provided with shape groove 22, 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 stretches into key
The part of keyhole 21 is inclined-plane, and the outside of drill chuck 2 is fixed on electric drill sheet provided with a ring shape shelves wall 4, the annular shelves wall 4
On body 1, the annular shelves wall 4 is provided with an opening 41, and the electric drill body 1 is interior to be provided with a passage 5, the passage 5
Provided with air bag 6, 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 it is another
One end is provided with gag lever post 10, and the top of the gag lever post 10 is electric drill button 9, and the electric drill button 9 is provided with stopper slot 91,
The side of the electric drill button 9 is provided with electric drill switch 11.
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 is rotated
Frictional force between shape groove 22.
The drill chuck 2 is provided with an instruction line, and when instruction line alignment opening 41, opening 41 is directed at keyhole 21.
As long as the present invention under normal circumstances operator pressing electric drill button, electric drill button lean electric drill switch after electric drill just
Setting in motion；The opening on annular groove is first directed at keyhole by operator during more bit change, and electric drill key 100 is then inserted key
Keyhole, electric drill key 100 leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, and one end of slide bar extruding gasbag makes
The gag lever post on the air bag other end is obtained to rise until in gag lever post insertion stopper slot, at this moment electric drill button is limited bar and blocked and nothing
Method is pressed, and electric drill key 100 is extracted after operator finishes changing drill bit, gag lever post is pressed down against air bag one under gravity
End, gag lever post departs from stopper slot, and the other end of air bag pushes back one end of slide bar in keyhole, and at this moment operator's pressing electric drill is pressed
Button, electric drill button touching electric drill switch, electric drill normal work.After said structure, even if operator does not power off in electric drill
In the case of more bit change will not also cause danger.
