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.Fool proof electric drill, including electric drill body and for installing drill bit
Drill chuck, be provided with a ring annular groove, the annular groove in the drill chuck and be provided with slide bar, the end of described slide bar one end is stretched
To 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 is fixed on electric drill body, and the annular shelves wall is provided with an opening, the other end of the slide bar
Extend in electric drill body and back-moving spring is provided between the inwall of electric drill body, the slide bar is provided with steel wire rope, institute
It is electric drill button to state connection on steel wire rope and slide below the gag lever post being located on slide rail, the gag lever post, the electric drill button
Stopper slot is provided with, the side of the electric drill button is switched provided with electric drill, and drill bit key is inserted key by operator during more bit change
Keyhole leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, and the steel wire rope on slide bar is toward gag lever post position directly above
It is mobile so that gag lever post is moved down in insertion stopper slot, and at this moment electric drill button is limited bar and blocks and can not press, and operator finishes changing
Drill bit key is extracted after drill bit, back-moving spring pushes back one end of slide bar in keyhole, the steel wire rope on slide bar drives gag lever post
Rise until gag lever post departs from stopper slot.
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
Drill bit key, is then inserted keyhole by opening alignment keyhole, and drill bit key leans the inclined-plane on slide bar so that the past electricity of slide bar
Bore and moved in body, the steel wire rope on slide bar is moved toward gag lever post position directly above so that gag lever post moves down insertion limit along slide rail
In the groove of position, at this moment electric drill button is limited bar and blocks and can not press, and operator finishes changing and drill bit key is extracted after drill bit, resets bullet
Spring pushes back one end of slide bar in keyhole, and the steel wire rope on slide bar drives gag lever post to rise along slide rail and limited until gag lever post departs from
Position groove, at this moment operator's pressing electric drill button, electric drill button touching electric drill switch, electric drill normal work.After said 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, anti-error behaviour
A ring annular groove 22 is provided with the electric drill of work, including electric drill body 1 and the drill chuck 2 for installing drill bit, the drill chuck 2,
Slide bar 3 is provided with the annular groove 22, the end of described one end of slide bar 3 is extended in the keyhole 21 of drill chuck 2, the slide bar 3
The part for stretching into keyhole 21 is inclined-plane, and the exterior measuring of drill chuck 2 is fixed on provided with a ring shape shelves wall 4, the annular shelves wall 4
On electric drill body 1, the annular shelves wall 4 is provided with an opening 41, and the other end of the slide bar 3 is extended in electric drill body 1
And back-moving spring 13 is provided between the inwall of electric drill body 1, the slide bar 3 is provided with steel wire rope 5, the steel wire rope 5
The gag lever post 7 being located on slide rail 6 is slided in connection, and the lower section of the gag lever post 7 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；During more bit change, operator needs that the opening on annular groove is first directed at keyhole, then drill bit key 100
Insert keyhole, drill bit key 100 leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, the steel wire rope on slide bar
Toward the movement of gag lever post position directly above so that gag lever post is moved down in insertion stopper slot along slide rail, and at this moment electric drill button is limited bar
Block and can not press, operator finishes changing extraction drill bit key 100 after drill bit, one end of slide bar is pushed back keyhole by back-moving spring
Interior, the steel wire rope on slide bar drives gag lever post to rise along slide rail until gag lever post departs from stopper slot, and at this moment operator presses electric drill
Button, electric drill button touching electric drill switch, electric drill normal work.After said structure, even if operator is not broken in electric drill
More bit change will not also cause danger in the case of electricity.
