Abstract
The invention discloses an electric drill which comprises an electric drill body and a drill chuck used for clamping a drill, wherein a keyhole is formed in the drill chuck; a first groove and a second groove are formed in the keyhole; an electromagnet is arranged in the first groove; a stop block is arranged in the second groove; the stop block is made of a magnetic material; a reset spring is arranged between the stop block and the second groove; and when the electric drill is energized, the electromagnet absorbs the stop block, and an electric drill key cannot be inserted into the keyhole. According to the electric drill, under the energized situation, the electric drill key cannot be inserted into the keyhole, so that an operator is effectively prevented from changing the drill under the energized situation, and the danger is effectively avoided.
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, can not more bit change when electric drill is energized.
The present invention is achieved through the following technical solutions.A kind of electric drill, comprise electric drill body and the drill chuck for clamping drilling bit, described drill chuck is provided with keyhole, be provided with the first groove and the second groove in described keyhole, in described first groove, be provided with electromagnet, in described second groove, be provided with block, described block adopts magnetic material to make, be provided with back-moving spring between described block and the second groove, when electric drill is energized, described electromagnet holds block and makes electric drill key to insert keyhole.
Compared with prior art, the present invention is in energising situation, electromagnet holds block, makes block block keyhole, and electric drill key just cannot to be inserted in keyhole more bit change by such operator, then they first can only give electric drill power-off, the magnetic force of electromagnet disappears, and block is got back in the second groove under the effect of back-moving spring, and at this moment electric drill key could insert keyhole, said structure effectively prevents operator's more bit change when electric drill is energized, and avoids causing danger.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of electric drill of the present invention drill chuck when not being energized.
The structural representation of drill chuck when Fig. 3 is electric drill of the present invention energising.
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 3, a kind of electric drill, comprise electric drill body 1 and the drill chuck 2 for clamping drilling bit, described drill chuck 2 is provided with keyhole 21, the first groove 3 and the second groove 4 is provided with in described keyhole 21, electromagnet 31 is provided with in described first groove 3, block 41 is provided with in described second groove 4, described block 41 adopts magnetic material to make, back-moving spring 42 is provided with between described block 41 and the second groove 4, when electric drill is energized, described electromagnet 31 holds block 41 and makes electric drill key cannot insert keyhole 21.
The present invention is in energising situation, electromagnet holds block, block is made to block keyhole, electric drill key just cannot to be inserted in keyhole more bit change by such operator, and then they can only first give electric drill power-off, the magnetic force disappearance of electromagnet, block is got back in the second groove under the effect of back-moving spring, at this moment electric drill key could insert keyhole, and said structure effectively prevents operator's more bit change when electric drill is energized, and avoids causing danger.
