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.Electric drill with anti-misoperation function, including electric drill body and be used for
Install to be provided with a ring annular groove, the annular groove in the drill chuck of drill bit, the drill chuck and be provided with slide bar, described slide bar one end
End extend in the keyhole of drill chuck, the part that the slide bar stretches into keyhole is inclined-plane, and the drill chuck exterior measuring is provided with
One ring shape shelves wall, the annular shelves wall is fixed on electric drill body, and the annular shelves wall is provided with an opening, the slide bar
The other end extend in electric drill body and be provided between the inwall of electric drill body under (the first back-moving spring, the slide bar
Side is provided with translation voussoir, the wedge surface of the translation voussoir and leaned provided with gag lever post, is electric drill button below the gag lever post,
The electric drill button is provided with stopper slot, and the side of the electric drill button is switched provided with electric drill, and the gag lever post is provided with one piece
One end of connection second back-moving spring below baffle plate, the baffle plate, the other end of the second back-moving spring leans electric drill button
Surface, more bit change when operator drill bit key inserted keyhole lean inclined-plane on slide bar so that slide bar is toward electric drill body
The wedge surface of translation voussoir on interior movement, slide bar is acted on gag lever post so that gag lever post is moved down in insertion stopper slot, at this moment electric
Brill button is limited bar and blocks and can not press, and drill bit key is extracted after drill bit when operator finishes changing, and (the first back-moving spring will be sliding
One end of bar is pushed back in keyhole, and second back-moving spring promotes gag lever post to move up until gag lever post departs from stopper slot.
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 body in move, the wedge surface of the translation voussoir on slide bar act on gag lever post so that gag lever post move down insert stopper slot in,
At this moment electric drill button is limited bar and blocks and can not press, and drill bit key is extracted after drill bit when operator finishes changing, and first resets bullet
Spring pushes back one end of slide bar in keyhole, and second back-moving spring promotes gag lever post to move up until gag lever post disengaging stopper slot, this
When operator pressing electric drill button, electric drill button touching electric drill switch, electric drill normal work.After said structure, even if behaviour
Author's more bit change in the case where electric drill is not powered off 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, with anti-
A ring is provided with the electric drill of maloperation function, including electric drill body 1 and the drill chuck 2 for installing drill bit, the drill chuck 2
Slide bar 3 is provided with shape groove 22, the annular groove 22, the end of described one end of slide bar 3 is extended in the keyhole 21 of drill chuck 2, institute
State slide bar 3 and stretch into the part of keyhole 21 for inclined-plane, the exterior measuring of drill chuck 2 is provided with a ring shape shelves wall 4, the annular shelves wall
4 are fixed on electric drill body 1, and the annular shelves wall 4 is provided with an opening 41, and the other end of the slide bar 3 extends to electric drill
(the first back-moving spring 13 is provided with body 1 and between the inwall of electric drill body 1, the lower section of the slide bar 3 is provided with translation wedge
Leaned on block 10, the wedge surface of the translation voussoir 10 provided with gag lever post 8, the lower section of the gag lever post 8 is electric drill button 11, described
Electric drill button 11 is provided with stopper slot 111, and the side of the electric drill button 11 is provided with electric drill switch 9, and the gag lever post 8 is provided with
One piece of baffle plate 12, one end of the lower section of the baffle plate 12 connection second back-moving spring 14, the other end of the second back-moving spring 14
Lean the surface of electric drill button 11.
