Background technology
Electric drill is the electric tool that people the most often use, and it has conveniently, inexpensive, the advantage such as be easy to carry, deeply by the favorable comment of workman in five metals, decoration industry.But operator often needs more bit change when using electric drill, because seek conveniently, operator is the direct more bit change when electric drill does not have power-off, if oneself or other people have touched switch and make bit drills move when more bit change by mistake, is very dangerous.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of electric drill.
The present invention is achieved through the following technical solutions.A kind of electric drill with anti-misoperation function, comprise electric drill body and the drill chuck for installing drill bit, a ring annular groove is provided with in described drill chuck, slide bar is provided with in described cannelure, the end of described slide bar one end extends in the keyhole of drill chuck, the part that described slide bar stretches into keyhole is inclined-plane, described drill chuck is surveyed outward and is provided with a ring shape shelves wall, described annular shelves wall is fixed on electric drill body, described annular shelves wall is provided with an opening, the other end of described slide bar to extend in electric drill body and and be provided with the first back-moving spring between the inwall of electric drill body, described slide bar is provided with translation voussoir, the below of described translation voussoir is provided with the lower wedge block coordinated with its wedge surface, slide rail is provided with below described lower wedge block, described slide rail slides and is provided with pad, the below of described pad is provided with the second back-moving spring, the side of described pad is provided with electric drill switch, the opposite side of described pad is provided with electric drill button, described pad is provided with two projections, described electric drill button is provided with two grooves coordinated with projection, more during bit change, operator makes slide bar move in electric drill body on the electric drill key insertion keyhole inclined-plane leaned on slide bar, translation voussoir on slide bar and lower wedge block interact and lower wedge block are moved down, and then pad is moved down until the projection on pad moves to groove location, at this moment operator presses electric drill button, projection inserts in groove, pad touches less than electric drill switch, operator extracts drill bit key after finishing changing drill bit, one end of slide bar pushes back in keyhole by the first back-moving spring, second back-moving spring promotes pad moves simultaneously, projection and groove stagger.
Further, described projection is distributed in the two ends of pad.
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, translation voussoir on slide bar and lower wedge block interact and lower wedge block are moved down, and then pad is moved down until the projection on pad moves to groove location, at this moment operator presses electric drill button, projection inserts in groove, pad touches less than electric drill switch, operator extracts drill bit key after finishing changing drill bit, one end of slide bar pushes back in keyhole by the first back-moving spring, second back-moving spring promotes pad moves simultaneously, projection and groove stagger, at this moment operator presses electric drill button, electric drill button promotes pad 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, a kind of electric drill with anti-misoperation function, 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, described slide bar 3 is provided with translation voussoir 14, the below of described translation voussoir 14 is provided with the lower wedge block 15 coordinated with its wedge surface, slide rail 8 is provided with below described lower wedge block 15, described slide rail 8 slides and is provided with pad 10, the below of described pad 10 is provided with the second back-moving spring 12, the side of described pad 10 is provided with electric drill switch 9, snap switch selected by described electric drill switch 9, the opposite side of described pad 10 is provided with electric drill button 11, described pad 10 is provided with two projections 101, described electric drill button 11 is provided with two grooves 111 coordinated with projection 101.
