Abstract
A handheld electric drill comprises an electric drill body and a drill chuck used for mounting a drill bit. A circle of annular groove is formed in the drill chuck. A sliding rod is arranged in the annular groove. One end of the sliding rod stretches into a key hole of the drill chuck. A circle of annular blocking wall is arranged on the outer side of the drill chuck. An opening is formed in the annular blocking wall. The other end of the sliding rod extends into the electric drill body, and a reset spring is arranged between the other end of the sliding rod and the inner wall of the electric drill body. A first push rod is hinged to the sliding rod. A second push rod arranged on a first sliding rail in a sliding mode is further hinged to the first push rod. A second sliding rail is connected to the lower end of the second push rod. A gasket is arranged on the second sliding rail in a sliding mode. An electric drill switch is arranged on one side of the gasket, and an electric drill button is arranged on the other side of the gasket. Two convex bocks are arranged on the gasket. Two grooves matched with the convex blocks are formed in the electric drill button. According to the handheld electric drill, no danger happens when an operator replaces the drill bit under the situation that the electric drill is not powered off.

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 hand held 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, the other end of described slide bar to extend in electric drill body and and be provided with back-moving spring between the inwall of electric drill body, one end of hinged first push rod on described slide bar, one end of hinged the second push rod be slidably arranged on the first slide rail of the other end of described first push rod, the other end of described second push rod connects the second slide rail, described second slide rail slides and is provided with pad, 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 the electric drill key insertion keyhole wedge surface leaned on slide bar, described slide bar moves and drives the first push rod be hinged on slide bar and the second pushrod movement be hinged on the first push rod, and then promotion pad moves 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 back-moving spring, 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, slide bar moves and drives the first push rod be hinged on slide bar and the second pushrod movement be hinged on the first push rod, and then promotion pad moves down, until the projection on pad moves to groove location, at this moment operator presses electric drill button, projection inserts in groove, pad is made to touch less than electric drill switch, drill bit key is extracted after operator finishes changing drill bit, one end of slide bar pushes back in keyhole by back-moving spring, first push rod drives the second push rod to rise along slide rail, pad also rises thereupon and gets back to original position, 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, after adopting said structure, even if 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.
Fig. 3 is the enlarged drawing at A place in Fig. 1.
Fig. 4 is the enlarged drawing at B place in Fig. 2.
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 hand held 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 back-moving spring 13 between the inwall of electric drill body 1, one end of hinged first push rod 6 on described slide bar 3, one end of hinged the second push rod 7 be slidably arranged on the first slide rail 8 of the other end of described first push rod 6, the other end of described second push rod 7 connects the second slide rail 12, described second slide rail 12 slides and is provided with pad 10, the side of described pad 10 is provided with electric drill switch 11, snap switch selected by described electric drill switch 11, the opposite side of described pad 10 is provided with electric drill button 9, described pad 10 is provided with two projections 101, described electric drill button 9 is provided with two grooves 91 coordinated with projection 101.
Described projection 101 is distributed in the two ends of pad 10, pad 10 uniform stressed when making operator presses electric drill button 9.
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.
