Be the Chinese utility model patent " direct current drive screwdriver " of ZL01271639.1 (notification number is CN2508901Y) as a patent No., reaching an application number is the Chinese invention patent " charged electric screwdriver " of ZL201010525872.1 (publication number is CN101983844A), and they have all disclosed such electric screw and have criticized structure.
Can run into the screw that will turn in actual use is positioned under the situation near metope or certain sidewall, because the output shaft during existing electric screw is criticized is arranged on the center position of housing front end face, may make the screwdriver bit that is installed on the output shaft forward insertion to turn screw because of stopping of electric screw screwdriver bit portion.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of can make work head and barrier interfere the few electric screw of area to criticize at above-mentioned prior art present situation, this electric screw is criticized the screw that can conveniently turn near for example metope or side-walls, is fit to nearly barrier operation.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of electric screw is criticized, include shell, be equipped with output shaft on the front end face of shell, output shaft is provided with cross section and is polygon-shaped screwdriver bit jack, be provided with in the shell in order to drive output shaft around self axis motor rotating, reach the power supply that motor is provided power, it is characterized in that: the eccentric edge that the front end face of also close shell is set of described output shaft.
Because operating habit, we generally can operate the upper edge of shell front end near barrier, so above-mentioned output shaft is arranged on the upper edge of front end face upper position and the close shell front end of shell.Meet conventional operating habit like this.
For with various types of screwdriver bit firm fixation in the screwdriver bit jack, the bottom in the above-mentioned screwdriver bit jack is provided with magnet.
Above-mentioned drive axle of motor links to each other with the output shaft transmission by gear reduction box, described gear reduction box has former and later two chambers, be provided with the planetary gear running part in the rear chamber, the front end that the power transmission shaft of planetary gear running part passes rear chamber enters in the front chamber, form first travelling gear on the outer peripheral face of described power transmission shaft, the rear end of described output shaft is located in the front chamber, and on the rear end of output shaft suit second travelling gear, described first travelling gear and second travelling gear are meshing with each other.By the improvement to gear reduction box, the output shaft of off-centre setting can be in transmission connection together by reduction gear box and drive axle of motor, can also guarantee simultaneously motor and gear reduction box also can with the coaxial setting of shell, allow motor and gear reduction box rational deployment in the enclosure.
Above-mentioned shell has horizontal body portion and is positioned at the rear end of body portion and the handle portion of extending downwards, and the front end face of described shell is on the front end face of body portion, and described motor and gear reduction box are located in the body portion, and described power supply is located in this handle portion.Handle portion is set to be made things convenient for us to hold to take the operation electric screw to criticize.
Front portion in the above-mentioned body portion is provided with the LED lamp, and this LED lamp front end stretches out described front end face, and the LED lamp is positioned at the below of output shaft.The LED lamp is set can convenient situation at insufficient light issues illumination to screw position to be turned, convenient this electric screw that uses under dark surrounds is criticized.
Compared with prior art, advantage of the present utility model is: because the eccentric edge that the front end face of also close shell is set of output shaft, spacing between output shaft and the shell front end edge edge is few, during operation, to be positioned at homonymy with barrier (as wall) near the shell front end edge edge of output shaft, can reduce the position area that interferes with barrier, this electric screw be criticized be fit to operate near barrier.
