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 fool proof electric drill, including electric drill body and for installing
The drill chuck of drill bit, the drill chuck is interior to be provided with a ring annular groove, and slide bar, the end of described slide bar one end are provided with the annular groove
Portion is extended in the keyhole of drill chuck, and the part that the slide bar stretches into keyhole is inclined-plane, and the drill chuck exterior measuring is provided with a circle
Annular shelves wall, the annular shelves wall are fixed on electric drill body, the annular shelves wall be provided with one opening, the slide bar it is another
One end extends in electric drill body and back-moving spring is provided between the inwall of electric drill body, and the slide bar is provided with steel wire
Restrict, the sliding block for sliding and being located on the first slide rail is connected on the steel wire rope, the sliding block connects the second slide rail, second slide rail
Interior slip is provided with pad, and the side of the pad is provided with drill switch, and the opposite side of the pad is provided with electric drill button, the pad
Piece is provided with two projections, and operator is electricity when the electric drill button is provided with two grooves, more bit change coordinated with projection
Bore key insertion keyhole and lean inclined-plane on slide bar so that slide bar is toward moving in electric drill body, the steel wire rope on slide bar, which drives, to be slided
Block is moved up, and then pad is moved up until the projection on pad is moved to groove location, and at this moment operator presses electric drill button, projection
Insert in groove, pad is touched less than drill switch, and operator finishes changing and electric drill key is extracted after drill bit, and back-moving spring is by the one of slide bar
End is pushed back in keyhole, and pad moves down, and projection staggers with groove.
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, the rope belt movable slider on slide bar is moved up along the first slide rail, and then pad is moved up until convex on pad
Block is moved to groove location, and at this moment operator presses electric drill button, and projection is inserted in groove so that pad touches to be opened less than electric drill
Close, operator extracts electric drill key after finishing changing drill bit, and back-moving spring pushes back one end of slide bar in keyhole, and sliding block is slided along first
Rail moves down, and then pad moves down, and projection staggers with groove, and at this moment operator presses electric drill button, and electric drill button promotes pad to touch
Touch drill switch, electric drill normal work.After said structure, bored even if operator changes in the case where electric drill does not power off
Head 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 Zhongfang
The electric drill of maloperation, 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 annular groove 22 is interior to be provided with slide bar 3, and the end of described one end of slide bar 3 is extended in the keyhole 21 of drill chuck 2, the cunning
The part that bar 3 stretches into 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 solid
It is scheduled 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 extends to electric drill body
Back-moving spring 13 is provided with 1 and 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 sliding block 7 being located on the first slide rail 6 is slided in upper connection, and the sliding block 7 connects the second slide rail 8, slides and set in second slide rail 8
There is pad 10, the side of the pad 10 is provided with drill switch 11, and the drill switch 11 selects snap switch, the pad 10
Opposite side be provided with electric drill button 9, the pad 10 is provided with two projections 101, the electric drill button 9 be provided with two with it is convex
The groove 91 that block 101 coordinates.
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；During more bit change, operator needs that the opening on annular groove is first directed at keyhole, then electric drill
Key inserts keyhole, and electric drill key leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, the steel wire on slide bar
Rope band movable slider is moved up along the first slide rail, and then pad is moved up until the projection on pad is moved to groove location, is at this moment operated
Person presses electric drill button, and projection is inserted in groove, and pad is touched less than drill switch, and operator extracts electric drill key after finishing changing drill bit
Spoon, back-moving spring push back one end of slide bar in keyhole, and sliding block moves down along the first slide rail, and then pad is moved down, projection
Stagger with groove, 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.
