Extend 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
Also meshed with one tooth plate, the first tooth plate meshing gear, the gear provided with the second tooth plate, second tooth plate is provided with flat
Move and leaned on voussoir, the wedge surface of the translation voussoir provided with gag lever post, be electric drill button, the electric drill below the gag lever post
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 described provided with one piece of baffle plate
One end of connection second back-moving spring below baffle plate, the other end of the second back-moving spring leans the surface of electric drill button, more
Drill bit key is inserted keyhole and leans inclined-plane on slide bar so that slide bar is toward moving in electric drill body by operator during bit change, sliding
The first tooth plate drive gear on bar is rotated, and gear drives the wedge surface of the translation voussoir on the movement of the second tooth plate, the second tooth plate to make
With causing gag lever post to move down in insertion stopper slot on gag lever post, at this moment electric drill button is limited bar and blocks and can not press, when
Operator finishes changing and drill bit key is extracted after drill bit, and (the first back-moving spring pushes back one end of slide bar in keyhole, and second resets bullet
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 and moved in body, the first tooth plate drive gear on slide bar is rotated, gear drives flat on the movement of the second tooth plate, the second tooth plate
The wedge surface for moving voussoir is acted on gag lever post so that gag lever post is moved down in insertion stopper slot, and at this moment electric drill button is limited bar and blocked
And can not press, drill bit key is extracted after drill bit when operator finishes changing, one end of slide bar is pushed back keyhole by (the first back-moving spring
Interior, the first tooth plate drive gear is rotated, and gear drives the movement of the second tooth plate, and second back-moving spring promotes gag lever post to move up until limit
Position bar departs from stopper slot, at this moment operator's pressing electric drill button, electric drill button touching electric drill switch, electric drill normal work.Using
After said structure, even if operator, in the case where electric drill is not powered 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, family expenses hand
Hold and a ring annular groove 22 be provided with formula electric drill, including electric drill body 1 and the drill chuck 2 for installing drill bit, the drill chuck 2,
Slide bar 3 is provided with the annular groove 22, the end of described one end of slide bar 3 is extended in the keyhole 21 of drill chuck 2, the slide bar 3
The part for stretching into keyhole 21 is inclined-plane, and the exterior measuring of drill chuck 2 is fixed on provided with a ring shape shelves wall 4, the annular shelves wall 4
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 (the first 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, described
Also meshed with the meshing gear 6 of first tooth plate 5, the gear 6 provided with the second tooth plate 7, second tooth plate 7 is provided with translation voussoir
14, it is described translation voussoir 14 wedge surface on lean provided with gag lever post 8, the lower section of the gag lever post 8 is electric drill button 11, the electricity
Bore button 11 and be provided with stopper slot 111, 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
Block baffle plate 15, one end of the lower section of the baffle plate 15 connection second back-moving spring 12, the other end top of the second back-moving spring 12
By the surface of electric drill button 11.
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 is rotated
Frictional force between shape groove 22.
