Provided with drill switch, the opposite side of the pad is provided with electric drill button, and the pad is provided with two projections, the electric drill button
Operator leans drill bit key insertion keyhole oblique on slide bar when being provided with two grooves, more bit change coordinated with projection
Face make it that the first magnet on slide bar is moved to the top position of the second magnet to slide bar with slide bar toward moving in electric drill body,
The second magnet moves down in the presence of magnet repulsion and then pad moves down, until the projection on pad is moved to groove location, this
When operator press electric drill button, in projection insertion groove, pad is touched less than drill switch, and operator finishes changing to extract after drill bit and bored
Head key, (the first back-moving spring push back one end of slide bar in keyhole, and the first magnet staggers with the second magnet, the repulsion of magnet
Disappear, second back-moving spring promotes pad to move up, 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
Drill bit key, is then inserted keyhole by opening alignment keyhole, and the inclined-plane that drill bit key is leaned on slide bar causes slide bar toward electricity
Bore and moved in body, the first magnet on slide bar is moved to the top position of the second magnet with slide bar, in the work of magnet repulsion
Moved down with lower second magnet and then pad moves down, until the projection on pad is moved to groove location, at this moment operator presses piezoelectricity
Button is bored, projection is inserted in groove, and pad is touched less than drill switch, and operator extracts drill bit key after finishing changing drill bit, and first is multiple
Position spring pushes back one end of slide bar in keyhole, and the first magnet staggers with the second magnet, and the repulsion of magnet disappears, and second resets
Spring promotes pad to move up, and projection staggers with groove, and at this moment operator presses electric drill button, and electric drill button promotes pad touching electricity
Bore switch, electric drill normal work.After said structure, even if operator electric drill not power off in the case of more bit change
It will not 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 are held, a ring annular groove 22, institute are provided with the drill chuck 2
State in annular groove 22 and be provided with slide bar 3, 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 is stretched
The part for entering keyhole 21 is inclined-plane, and the outside of drill chuck 2 is provided with a ring shape shelves wall 4, and the annular shelves wall 4 is fixed on electricity
Bore on 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 simultaneously
And (the first back-moving spring 13 is provided between the inwall of electric drill body 1, and the lower section of the slide bar 3 is provided with the first magnet 5, and described
The lower section of one magnet 5 is provided with magnetic receiver 7, and the second magnet 6, the magnet 6 of the first magnet 5 and second are provided with the magnetic receiver 7
Opposite face magnetic pole it is identical, the lower section of second magnet 6 is provided with magnetic slide rail 8, and the magnetic slide rail 8 is adsorbed in the second magnet
Slided on 6, in the magnetic 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
