Description
Technical field
The invention belongs to field of power tools, be specifically related to a kind of electric drill.
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.There is the electric drill of 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, the below of described slide bar is provided with translation voussoir, the wedge surface of described translation voussoir leans and is provided with gag lever post, the below of described gag lever post is electric drill button, described electric drill button is provided with stopper slot, the side of described electric drill button is provided with electric drill switch, described gag lever post is provided with one piece of baffle plate, one end of the second back-moving spring is connected below described baffle plate, the other end of described second back-moving spring leans the surface of electric drill button, 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, the wedge surface of the translation voussoir on slide bar 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, second back-moving spring promotes gag lever post to move until gag lever post departs from stopper slot.
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 wedge surface of the translation voussoir on slide bar 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, 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, there is the electric drill of 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, the below of described slide bar 3 is provided with translation voussoir 10, the wedge surface of described translation voussoir 10 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 12, one end of the second back-moving spring 14 is connected below described baffle plate 12, the other end of described second back-moving spring 14 leans the surface of electric drill button 11.
Described slide bar 3 is provided with a circle ball with the contact surface of cannelure 22, reduces the frictional force between slide bar 3 and cannelure 22 when drill chuck 2 rotates.
Described drill chuck 2 is provided with an index line, and when index line aims at opening 41, opening 41 aims at keyhole 21.
As long as the present invention is operator's pressing electric drill button under normal circumstances, after electric drill button leans electric drill switch, electric drill is with regard to setting in motion, more during bit change, 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 wedge surface of the translation voussoir on slide bar 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, 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.
