The annular shelves wall is fixed on electric drill body, and the annular shelves wall is provided with an opening, the other end extension of the slide bar
Back-moving spring is provided with electric drill body and between the inwall of electric drill body, the lower section of the slide bar is provided with the first tooth plate,
The lower section engagement of first tooth plate is provided with gear assembly, and the gear assembly also meshes with the second tooth plate, second tooth plate
Bottom is provided with slide rail, is slided on the slide rail and is provided with pad, and the side of the pad is provided with drill switch, the pad it is another
Side is provided with electric drill button, and the pad is provided with two projections, the electric drill button be provided with two it is recessed with projection cooperation
Electric drill key insertion keyhole is leaned inclined-plane on slide bar so that slide bar is toward moving in electric drill body by operator during groove, more bit change
Dynamic, the slide bar movement drives the first tooth plate, gear assembly and the second tooth plate to move so that moving to groove location on pad, at this moment
Operator presses electric drill button, and projection is inserted in groove, and pad is touched less than drill switch, extracts and bores after operator finishes changing drill bit
Head key, back-moving spring push back one end of slide bar in keyhole, 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, for the present invention in more bit change in the case of energization, operator will be first opening on annular groove
Electric drill key, is then inserted keyhole, the inclined-plane that electric drill key is leaned on slide bar causes slide bar toward electric drill by mouth alignment keyhole
Moved in body, the slide bar movement drives the first tooth plate and gear assembly motion so that the second tooth engaged with gear assembly
Plate moves up, and then moves up to groove location, at this moment operator's pressing electric drill button, projection and inserted in groove with mobile gasket, pad
Touch less than drill switch, drill bit key is extracted after operator finishes changing drill bit, one end of slide bar is pushed back keyhole by back-moving spring
Interior, the first tooth plate drive gear assemblies rotate, and gear assembly drives the second tooth plate to move down, and pad also returns to original position therewith,
Projection staggers with groove, and at this moment operator presses electric drill button, and electric drill button promotes pad touching drill switch, the normal work of electric drill
Make.After said structure, even if operator, in the case where electric drill does not power 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, a kind of hand
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, described
Slide bar 3 is provided with annular 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
The part of keyhole 21 is designed in wedge surface, and the exterior measuring of drill chuck 2 is provided with a ring shape shelves wall 4, and the annular shelves wall 4 is fixed on
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 lower section of the slide bar 3 is provided with the first tooth plate 5, and described first
The lower section engagement of tooth plate 5 is provided with gear assembly 6, and the gear assembly 6 also meshes with the second tooth plate 7, the lower end of second tooth plate 7
Portion is provided with slide rail 8, is slided on the slide rail 8 and is provided with pad 10, the side of the pad 10 is provided with drill switch 9, the electric drill
Switch 9 selects snap switch, and the opposite side of the pad 10 is provided with electric drill button 11, and the pad 10 is 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 both ends of pad 10 so that operator press electric drill button 11 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；Operator during more bit change is needed the opening on annular groove to be first directed at keyhole, then electricity
Key insertion keyhole is bored, electric drill key leans the wedge surface on slide bar so that slide bar is toward moving in electric drill body, and the slide bar moves
It is dynamic to drive the first tooth plate and gear assembly motion so that the second tooth plate engaged with gear assembly moves up, and then with mobile gasket
Groove location is moved to, at this moment operator presses electric drill button, and projection is inserted in groove, and pad is touched less than drill switch, works as operation
