Abstract
The present invention relates to electric tool, and is especially a kind of electric screw driver suitable for screwing in and screwing out screws and nuts of 1.6-4 mm diameter. The electric screw driver includes miniature motor, cell, rotation direction control switch, planetary gear reducing mechanism with outside set reducing box and output driver bar. The present invention has firm structure. The present invention has also locking unit, which has the function of automatically changing to hand operation in case of excessive torque of screw and nut, and casing of transparent material to makes it possible for the operator to monitor the work state of inside planetary gears.
Description
Technical field
The present invention relates to electric tool, relate in particular to the electric screw driver of a kind of M1.6 of being applicable to～M4 screw, nut dismounting.
Background technology
Existing in the market electric screw the Knife tool various in style is widely used in student and vast dynamo-electric fan, mostly the electronic screwdriver tool of small-sized DC, owing to structural reason, also be provided with shell in the gear-box outside, volume increases makes structure not compact, and moulding is not attractive in appearance.
Technology contents
At above problem, the invention provides a kind of gear-box double as shell, compact conformation is firm, outward appearance novelty, the electric screw driver of suitable more M1.6～M4 screw, nut dismounting.
Technical scheme of the present invention is to realize like this, it comprises micromachine, battery, rotating gauge tap, planetary gear reducing mechanism and output knife bar, reduction box in the planetary gear reducing mechanism is external, reduction box and upper and lower shell body adopt tenon structure snapping, and form the cutter hub of electric screw driver jointly, the reduction box inwall is profile of tooth and meshes with planetary gear.
Reduction box adopts transparent material to make.
Be provided with interior lining ring in the reduction box casing in the described reducing gear, the cylindrical of interior lining ring is provided with at least 2 positioning tooths, and with the engagement of reduction box internal tooth, the tenon of upper and lower shell body is fixed on the interior lining ring cylindrical.
Described output knife bar end also is provided with outer cover, and the output knife bar is provided with locking groove, also is provided with stop device on the outer cover.
Described stop device comprises button, is provided with arresting lever below button, and arresting lever is arranged with spring outward, the outside socket lining of output knife bar.
Described planetary gear adopts color material to make.
Described transparent material adopts transparent plastic, organic transparent material.
The present invention makes structure firm stable more, the outward appearance novelty owing to adopted gear reduction box external and be connected to form one with shell tenon shape.Stop device has solved when meeting big torsion screw, nut, change manual function into, adopt transparent material to make casing, color material is made internals, make the operator in use can monitor planetary duty at any time, and can recognize the operation principle of frame for movement.
