Abstract
A household electric drill comprises an electric drill body, and a drill chuck for mounting a drill bit, wherein a circle of annular groove is formed in the drill chuck, and a sliding rod is arranged in the annular groove; the end part of one end of the sliding rod extends into a key hole in the drill chuck; the part, extending into the key hole, of the sliding rod is an inclined surface; a circle of annular stopping wall is arranged at the outer side of the drill chuck and fixed to the electric drill body; an opening is formed in the annular stopping wall; a channel in which an air bag is arranged is mounted in the electric drill body; the other end of the sliding rod extends into the electric drill body and abuts against one end of the air bag; a limiting rod above which an electric drill button is arranged is mounted at the other end of the air bag; a limiting groove is formed in the electric drill button; an electric drill switch is arranged at one side of the electric drill button. According to the household electric drill adopting the aforementioned structure, an operator can safely replace the drill bit in case that the electric drill is not powered off.
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.Household electric drill, 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, a passage is provided with in described electric drill body, air bag is provided with in described passage, the other end of described slide bar to extend in electric drill body and leans one end of air bag, the other end of described air bag is provided with gag lever post, the top 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, 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, one end of slide bar extruding gasbag makes the gag lever post on the air bag other end rise until gag lever post inserts in 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, gag lever post is downward extruding gasbag one end under gravity, gag lever post departs from stopper slot, one end of slide bar pushes back in keyhole by the other end of air bag.
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, one end of slide bar extruding gasbag makes the gag lever post on the air bag other end rise until gag lever post inserts in 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, gag lever post is downward extruding gasbag one end under gravity, gag lever post departs from stopper slot, one end of slide bar pushes back in keyhole by the other end of air bag, 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 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, a passage 5 is provided with in described electric drill body 1, air bag 6 is provided with in described passage 5, the other end of described slide bar 3 to extend in electric drill body 1 and leans one end of air bag 6, the other end of described air bag 6 is provided with gag lever post 10, the top of described gag lever post 10 is electric drill buttons 9, described electric drill button 9 is provided with stopper slot 91, the side of described electric drill button 9 is provided with electric drill switch 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 first aims at keyhole the opening on cannelure, 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, one end of slide bar extruding gasbag makes the gag lever post on the air bag other end rise until gag lever post inserts in 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, gag lever post is downward extruding gasbag one end under gravity, gag lever post departs from stopper slot, one end of slide bar pushes back in keyhole by the other end of air bag, 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.
