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 Household handheld electric drill, including electric drill body and for installing
It is provided with the drill chuck of drill bit, 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
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 is fixed on electric drill body, the annular shelves wall provided with one opening, the slide bar it is another
One end extends in electric drill body and is provided between the inwall of electric drill body below (the first back-moving spring, the slide bar and set
Have and also meshed with the first tooth plate, the first tooth plate meshing gear, the gear provided with the second tooth plate, set on second tooth plate
There is lower wedge block, the lower section of the lower wedge block is provided with below the upper voussoir coordinated with its wedge surface, the upper voussoir and is provided with slide rail, described
Slided on 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 switched provided with electric drill,
The opposite side of the pad is provided with electric drill button, the pad provided with two projections, the electric drill button provided with two with
Drill bit key insertion keyhole is leaned the inclined-plane on slide bar so that slide bar is past by operator during the groove, more bit change that projection coordinates
Moved in electric drill body, the first tooth plate drive gear on slide bar is rotated, gear is driven on the movement of the second tooth plate, the second tooth plate
Lower wedge block and upper voussoir, which interact, causes upper voussoir to move down, so cause 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
Drill bit key is extracted after head, (the first back-moving spring pushes back one end of slide bar in keyhole, while second back-moving spring promotes pad
Piece is moved up, and 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
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 first tooth plate drive gear on slide bar is rotated, under gear is driven on the movement of the second tooth plate, the second tooth plate
Voussoir interacts with upper voussoir causes upper voussoir to move down, and then pad is moved down until the projection on pad is moved to groove
In position, at this moment operator's pressing electric drill button, projection insertion groove, pad is touched less than electric drill switch, and operator finishes changing drill bit
After extract drill bit key, (the first back-moving spring pushes back one end of slide bar in keyhole, at the same second back-moving spring promote pad
Move up, projection staggers with groove, at this moment operator's pressing electric drill button, 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 endanger
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 hand held 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, 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 consolidated provided with a ring shape shelves wall 4, the annular shelves wall 4
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
(the first back-moving spring 13 is provided with 1 and between the inwall of electric drill body 1, the lower section of the slide bar 3 is provided with the first tooth plate 5,
Also meshed with the meshing gear 6 of first tooth plate 5, the gear 6 provided with the second tooth plate 7, second tooth plate 7 is provided with hyposphene
Block 14, the lower section of the lower wedge block 14 is provided with the upper voussoir 15 coordinated with its wedge surface, and the upper lower section of voussoir 15 is provided with slide rail 8,
Slided on 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 side of the pad 10
Provided with electric drill switch 9, the electric drill switch 11 selects snap switch, and the opposite side of the pad 10 is provided with electric drill button 11, institute
Pad 10 is stated provided with two projections 101, 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 9 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 drill bit
Key 100 inserts keyhole, and drill bit key 100 leans the inclined-plane on slide bar so that slide bar is toward moving in electric drill body, on slide bar
The first tooth plate drive gear rotate, gear drives the movement of the second tooth plate, lower wedge block and upper voussoir phase interaction on the second tooth plate
With causing upper voussoir to move down, and then pad is moved down until the projection on pad is moved to groove location, at this moment operator presses
Piezoelectricity is bored in button, projection insertion groove, and pad is touched less than electric drill switch, and operator finishes changing extraction drill bit key 100 after drill bit,
(the first back-moving spring pushes back one end of slide bar in keyhole, while second back-moving spring promotes pad to move up, projection and groove
Stagger, at this moment operator's pressing electric drill button, electric drill button promotes pad touching electric drill switch, electric drill normal work.Using upper
State after structure, even if operator, in the case where electric drill is not powered off, more bit change will not also cause danger.
