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.A kind of electric drill with anti-misoperation function, including electric drill body and
It is provided with drill chuck for installing drill bit, the drill chuck in a ring annular groove, the annular groove and is provided with slide bar, the slide bar
The end of one end is extended in the keyhole of drill chuck, and the part that the slide bar stretches into keyhole is inclined-plane, the drill chuck exterior measuring
Provided with a ring shape shelves wall, the annular shelves wall is fixed on electric drill body, and the annular shelves wall is described provided with an opening
The other end of slide bar extends in electric drill body and (the first back-moving spring, the slide bar is provided between the inwall of electric drill body
Provided with translation voussoir, the lower section of the translation voussoir is provided with below the lower wedge block coordinated with its wedge surface, the lower wedge block and is provided with
Slided on slide rail, the slide rail and be provided with pad, the lower section of the pad is provided with second back-moving spring, and the side of the pad is provided with
Electric drill is switched, and the opposite side of the pad is provided with electric drill button, and the pad is provided with two projections, the electric drill button and set
Electric drill key insertion keyhole is leaned the inclined-plane on slide bar and made by operator when having two grooves, more bit change coordinated with projection
Slide bar toward moving in electric drill body, the translation voussoir on slide bar is interacted with lower wedge block so that lower wedge block is moved down, and then is made
Obtain pad to move down until the projection on pad is moved to groove location, at this moment operator's pressing electric drill button, projection inserts groove
Interior, pad is touched less than electric drill switch, and operator finishes changing extraction electric drill key after drill bit, and (the first back-moving spring pushes away one end of slide bar
Return in keyhole, while second back-moving spring promotes pad to move up, projection staggers with groove.
Further, the projection is distributed in the two 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 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, the translation voussoir on slide bar interacts with lower wedge block causes lower wedge block to move down, and then pad is moved down
Until the projection on pad is moved to groove location, at this moment operator's pressing electric drill button, projection is inserted in groove, and pad is touched not
To electric drill switch, operator finishes changing extraction electric drill key after drill bit, and (the first back-moving spring pushes back one end of slide bar in keyhole,
Second back-moving spring promotes pad to move up simultaneously, and projection staggers with groove, and at this moment operator's pressing electric drill button, electric drill button is pushed away
Mobile gasket touching electric drill switch, electric drill normal work.After said structure, even if the situation that operator does not power off in electric drill
Under 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, a kind of tool
Have and one is provided with the electric drill of anti-misoperation function, including electric drill body 1 and the drill chuck 2 for installing drill bit, the drill chuck 2
Slide bar 3 is provided with ring annular groove 22, the annular groove 22, the end of described one end of slide bar 3 extends the keyhole 21 of drill chuck 2
Interior, the part that the slide bar 3 stretches into keyhole 21 is inclined-plane, and the outside of drill chuck 2 is provided with a ring shape shelves wall 4, the ring
Shape shelves wall 4 is fixed on electric drill body 1, and the annular shelves wall 4 is provided with an opening 41, the other end extension of the slide bar 3
(the first back-moving spring 13 is provided with electric drill body 1 and between the inwall of electric drill body 1, the slide bar 3 is provided with translation
Voussoir 14, the lower section of the translation voussoir 14 is provided with the lower wedge block 15 coordinated with its wedge surface, and the lower section of lower wedge block 15, which is provided with, to be slided
Slided on rail 8, the slide rail 8 and be provided with pad 10, the lower section of the pad 10 is provided with second back-moving spring 12, the pad 10
Snap switch is selected in side provided with electric drill switch 9, the electric drill switch 9, and the opposite side of the pad 10 is provided with electric drill button 11,
The pad 10 is provided with two projections 101, and the electric drill button 11 is provided with two grooves 111 coordinated with projection 101.
The projection 101 is distributed in the two ends of pad 10 so that during operator's pressing electric drill button 11 pad 10 it is uniform 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 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 operator presses electric drill button to the present invention under normal circumstances, electric drill button promotes pad to lean electric drill switch
Electric drill begins to motion 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 100 leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, flat on slide bar
Moving voussoir and lower wedge block and interacting causes lower wedge block to move down, and then so that pad move down until the projection on pad be moved to it is recessed
In groove location, at this moment operator's pressing electric drill button, projection insertion groove, pad is touched less than electric drill switch, and operator finishes changing brill
Electric drill key 100 is extracted after head, (the first back-moving spring pushes back one end of slide bar in keyhole, while second back-moving spring is promoted
Pad is moved up, and projection staggers with groove, at this moment operator's pressing electric drill button, and electric drill button promotes pad 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 be sent out
It is raw dangerous.
