End is extended in electric drill body and is provided with back-moving spring between the inwall of electric drill body, and rod set is arranged with the slide bar,
The rod set is not in contact with slide bar, in addition to link assembly, and one end of the link assembly is hinged in rod set, the connecting rod
The other end of component is hinged on slide bar, and the lower section of the link assembly is provided with adjustable end stop, is set below the adjustable end stop
There is fixed dam, cause adjustable end stop to lean connection rod set always provided with compression spring between the adjustable end stop and fixed dam
Part, is fixed with push rod on the adjustable end stop, and one end of the push rod passes through fixed dam, and the push rod is through fixed dam
One end 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 link assembly on slide bar, which moves, causes compression spring to promote adjustable end stop to rise, and then causes pad to increase until pad
On projection be moved to groove location, at this moment operator press electric drill button, projection insertion groove in, pad touches to be opened less than electric drill
To close, operator extracts electric drill key after finishing changing drill bit, and back-moving spring pushes back one end of slide bar in keyhole, while on slide bar
Link assembly pushes adjustable end stop so that pad declines, 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 link assembly on slide bar, which moves, causes compression spring to promote adjustable end stop to rise, and then causes on pad
Rise until the projection on pad is moved to groove location, at this moment operator presses electric drill button, and projection is inserted in groove, and pad touches
Less than drill switch, operator finishes changing electric drill key after drill bit, and back-moving spring pushes back one end of slide bar in keyhole, simultaneously sliding
Link assembly on bar pushes adjustable end stop so that pad declines, and projection staggers with groove, and at this moment operator presses electric drill button,
Electric drill button promotes pad touching drill switch, electric drill normal work.After said structure, even if operator does not have in electric drill
More bit change will not also cause danger in the case of power-off.
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 electric hand drill, including electric drill body 1 and the drill chuck 2 for installing drill bit, it is characterised in that：It is provided with the drill chuck 2
One 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 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 exterior measuring 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
Back-moving spring 13 is provided with electric drill body 1 and between the inwall of electric drill body 1, rod set 31 is arranged with the slide bar 3,
The rod set 31 is not in contact with slide bar 3, in addition to link assembly 14, and one end of the link assembly 14 is hinged on rod set 31
On, the other end of the link assembly 14 is hinged on slide bar 3, and the lower section of the link assembly 14 is provided with adjustable end stop 5, described
The lower section of adjustable end stop 5 is provided with fixed dam 6, and compression spring 12 is provided between the adjustable end stop 5 and fixed dam 6 and to rise
Downshift plate 5 leans link assembly 14 always, and push rod 7 is fixed with the adjustable end stop 5, and one end of the push rod 7, which passes through, to be fixed
Baffle plate 6, one end of the push rod 7 through fixed dam 6 is provided with slide rail 8, is slided on the slide rail 8 and be provided with pad 10, described
