Description
Technical field
The utility model relates to electric screwdriver, particularly relates to a kind of electric screwdriver of one-hand operation.
Background technology
Electric screwdriver, also known as electric screw driver, is rotate by driven by motor driver bit the instrument realizing automatic screw-driving.Electric screwdriver is often equipped with multiple different driver bit, to be applicable at present the screw of number of different types on the market.But a lot of electric screwdriver is not owing to itself possessing the function of storage cutter, and driver bit needs to be placed in other parcel tray, and this causes driver bit easily to be lost, and carry also inconvenient.For solving this problem, also the electric screwdriver had is provided with storage cutterhead, different driver bits is placed in storage cutterhead, but when changing driver bit, need manually will move after driver bit and advance, this just causes user must bimanualness (i.e. a hand-held electric screwdriver, moves after a hand propelled driver bit or advance), inconvenient operation.
Summary of the invention
Technical problem to be solved in the utility model is to provide the electric screwdriver that a kind of user singlehanded can carry out withdrawing and feed operation.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of electric screwdriver of one-hand operation, comprise housing, the front end of described housing is connected with the cutter head fixed cover matched with driver bit, driver bit described in described cutter head fixed cover drives rotates together, is provided with automatic withdrawal mechanism in described housing.
Described automatic withdrawal mechanism comprises push rod, slide block, seesaw, extension spring and the second spring, the both sides of described slide block are fixedly connected with slip lid respectively, described slip lid is positioned at the outside of described housing and is slidably matched with described housing, middle part and the described housing of described seesaw are coupling, the front end of described seesaw is provided with draw-in groove, described slide block has been wholely set fixture block, described fixture block snaps in described draw-in groove, between the rear end that the second described spring top is connected on described seesaw and described housing, the front end of described extension spring is fixedly connected with described slide block, the rear end of described extension spring is fixedly connected with described housing, described push rod and described cutter head fixed cover are coaxially arranged, the rear end of described push rod is connected to push rod in described slide block and described and can rotates around the longitudinal center line of self, the front end of described push rod is stretched in described cutter head fixed cover, shape of cross section and the described cutter head fixed cover of described push rod match, cutter head fixed cover described in described push rod drives rotates together, the front end of described push rod is fixedly installed the magnet for adsorbing described driver bit.
The shape of cross section of described push rod is regular hexagon.
Compared with prior art, the utility model has the advantages that owing to being provided with automatic withdrawal mechanism in housing, when driver bit changed by needs, just can be completed withdrawing and the feed process of driver bit by automatic withdrawal mechanism user one hand, simple to operation.

Fig. 2 is internal structure schematic diagram of the present utility model;
Fig. 3 is decomposing schematic representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in the figure, a kind of electric screwdriver of one-hand operation, comprise housing 1, the front end of housing 1 is connected with the cutter head fixed cover 3 matched with driver bit 2, cutter head fixed cover 3 drives driver bit 2 to rotate together, automatic withdrawal mechanism is provided with in housing 1, automatic withdrawal mechanism comprises push rod 4, slide block 41, seesaw 42, extension spring 43 and spring 44, the both sides of slide block 41 are fixedly connected with slip lid 45 respectively, slip lid 45 is positioned at the outside of housing 1 and is slidably matched with housing 1, middle part and the housing 1 of seesaw 42 are coupling, the front end of seesaw 42 is provided with draw-in groove 421, slide block 41 is wholely set fixture block 411, fixture block 411 snaps in draw-in groove 421, spring 44 apical grafting is between the rear end of seesaw 42 and housing 1, the front end of extension spring 43 is fixedly connected with slide block 41, the rear end of extension spring 43 is fixedly connected with housing 1, push rod 4 and cutter head fixed cover 3 are coaxially arranged, the rear end of push rod 4 is connected in slide block 41 and push rod 4 can rotate around the longitudinal center line of self, the front end of push rod 4 is stretched in cutter head fixed cover 3, the shape of cross section of push rod 4 is regular hexagon and matches with cutter head fixed cover 3, push rod 4 is with dynamic cutter head fixed cover 3 to rotate together, the front end of push rod 4 is fixedly installed the magnet (not shown) for adsorbing driver bit 2.
In above-described embodiment, the process that this electric screwdriver realizes singlehanded withdrawing and feed is: with the rear end of thumb press seesaw 42, the front end of seesaw 42 tilts, draw-in groove 421 on seesaw 42 departs from the fixture block 411 on slide block 41, slide block 41 is rapid backward under the pulling force effect of extension spring 43, slip lid 45 also rapid backward together thereupon, slide block 41 drives push rod 4 and driver bit 2 rapid backward simultaneously, driver bit 2 is return in the storage cutterhead of electric screwdriver, then thumb decontrols seesaw 42, and seesaw 42 resets under the effect of spring 44; Rotate storage cutterhead, the front end of push rod 4 is made to adsorb another driver bit 2 stored up in cutterhead, use thumb driven forward slip lid 45 again, slip lid 45 is with movable slider 41 to move forward, and extension spring 43 is stretched, and slide block 41 promotes push rod 4, driver bit 2 stretches in cutter head fixed cover 3 together, after slide block 41 moves forward and puts in place, fixture block 411 on slide block 41 snaps in the draw-in groove 421 on seesaw 42, and last thumb decontrols slip lid 45, completes withdrawing and the feed of driver bit 2.
