Further, the contact surface of described slide bar and cannelure is provided with a circle ball.
Further, described drill chuck is provided with an index line.
Compared with prior art, the present invention in energising situation more bit change time, operator needs first the opening on cannelure to be aimed at keyhole, then electric drill key is inserted keyhole, the electric drill key inclined-plane leaned on slide bar makes slide bar move in electric drill body, the first tooth plate driven wheel on slide bar rotates, gear driven second tooth plate moves, the wedge surface of the translation voussoir on the second tooth plate acts on gag lever post and makes gag lever post move down in insertion stopper slot, at this moment the limited bar of electric drill button blocks and cannot press, drill bit key is extracted after operator finishes changing drill bit, one end of slide bar pushes back in keyhole by the first back-moving spring, first tooth plate driven wheel rotates, gear driven second tooth plate moves, second back-moving spring promotes gag lever post moves until gag lever post departs from stopper slot, at this moment operator presses electric drill button, electric drill button touching electric drill switch, electric drill normally works.Adopt after said structure, though operator when electric drill does not have power-off more bit change also can not cause danger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 be the present invention more bit change time structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.As shown in Figure 1 to Figure 2, Household handheld electric drill, comprise electric drill body 1 and the drill chuck 2 for installing drill bit, a ring annular groove 22 is provided with in described drill chuck 2, slide bar 3 is provided with in described cannelure 22, the end of described slide bar 3 one end extends in the keyhole 21 of drill chuck 2, the part that described slide bar 3 stretches into keyhole 21 is inclined-plane, the outer survey of described drill chuck 2 is provided with a ring shape shelves wall 4, described annular shelves wall 4 is fixed on electric drill body 1, described annular shelves wall 4 is provided with an opening 41, the other end of described slide bar 3 to extend in electric drill body 1 and and be provided with the first back-moving spring 13 between the inwall of electric drill body 1, the below of described slide bar 3 is provided with the first tooth plate 5, described first tooth plate 5 meshing gear 6, on described gear 6, also engagement is provided with the second tooth plate 7, described second tooth plate 7 is provided with translation voussoir 14, the wedge surface of described translation voussoir 14 leans and is provided with gag lever post 8, the below of described gag lever post 8 is electric drill buttons 11, described electric drill button 11 is provided with stopper slot 111, the side of described electric drill button 11 is provided with electric drill switch 9, described gag lever post 8 is provided with one piece of baffle plate 15, one end of the second back-moving spring 12 is connected below described baffle plate 15, the other end of described second back-moving spring 12 leans the surface of electric drill button 11.
