State annular shelves wall to be fixed on electric drill body, the annular shelves wall is provided with an opening, and the other end of the slide bar extends to
In electric drill body and (the first back-moving spring is provided between the inwall of electric drill body, the lower section of the slide bar is provided with the first tooth
Plate, the first tooth plate meshing gear, also mesh with the gear and be provided with the first magnetic provided with the second tooth plate, second tooth plate
Iron, the lower section of second tooth plate are provided with magnetic receiver, the second magnet, first magnet and the second magnetic are provided with the magnetic receiver
The opposite face magnetic pole of iron is identical, and the lower section of second magnet is provided with magnetic slide rail, and the magnetic slide rail absorption is in the second magnet
On, slided in the magnetic 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 set
There is a drill switch, the opposite side of the pad is provided with electric drill button, and the pad is provided with two projections, on the electric drill button
Operator leans drill bit key insertion keyhole on the inclined-plane on slide bar during provided with two grooves, more bit change coordinated with projection
So that slide bar, toward moving in electric drill body, the first tooth plate drive gear on slide bar rotates, gear drives the movement of the second tooth plate, the
The first magnet on two tooth plates is moved to the top position of the second magnet with the second tooth plate, second in the presence of magnet repulsion
Magnet is moved down and then moved down with mobile gasket, and until the projection on pad is moved to groove location, at this moment operator presses electric drill and pressed
Button, projection are inserted in groove, and pad is touched less than drill switch, and operator extracts drill bit key after finishing changing drill bit, and first resets bullet
Spring pushes back one end of slide bar in keyhole, and the first magnet staggers with the second magnet, and magnet repulsion disappears, and second back-moving spring pushes away
Mobile gasket moves 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
Boring and moved in body, the first tooth plate drive gear on slide bar rotates, and gear drives the movement of the second tooth plate, and the on the second tooth plate
One magnet is moved to the top position of the second magnet with the second tooth plate, in the presence of magnet repulsion the second magnet move down and then
Band mobile gasket moves down, and until the projection on pad is moved to groove location, at this moment operator presses electric drill button, and projection insertion is recessed
In groove, pad is touched less than drill switch, and operator, which finishes changing, extracts drill bit key after drill bit, and (the first back-moving spring is by one end of slide bar
Push back in keyhole, the first tooth plate drive gear rotates, and gear drives the movement of the second tooth plate, and the first magnet and the second magnet are wrong
Open, magnet repulsion disappears, and second back-moving spring promotes pad to move up, and projection staggers with groove, and at this moment operator presses electric drill and pressed
Button, electric drill button promote pad touching drill switch, electric drill normal work.After said structure, even if operator is in electric drill
More bit change will not also cause danger in the case of not powering 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, electricity is held
Bore, including electric drill body 1 and the drill chuck 2 for installing drill bit, it is characterised in that：A ring shape is provided with the drill chuck 2
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, described
