Description
Technical field
The utility model relates to a kind of electric screw to be criticized.
Background technology
Screwdriver is the daily apparatus that is used for the dismounting screw, because the operating process of dismounting screw is the mechanical movement of repetition, people generally use electric screw to criticize this process of accomplishing at present.But the electric screw of prior art is criticized when under the more weak situation of surround lighting, using, and screwdriver bit is difficult to aim at the screw of desiring dismounting, and the worker need hold illuminations on the other hand, and holding electric screw criticizes operating difficulties on the other hand.Especially under night open-air environment, the worker need use illuminations to check working environment, road conditions etc., usually need be used alternatingly that electric screw is criticized and illuminations, and two kinds of instruments account for to such an extent that volume is big in the tool box, and quality is heavy, operation inconvenience.
Summary of the invention
The technical problem that the utility model will solve is that the deficiency to above-mentioned prior art exists provides a kind of electric screw that can throw light on itself to criticize.
The technical solution of the utility model is: a kind of electric screw is criticized; Comprise shell, be equipped with battery, motor and cradle in the shell, shell one end is provided with the output shaft by the motor-driven rotation; Shell is provided with first switch that is used to control the motor power break-make; Motor links to each other with the battery electricity, and string has first switch on the loop of motor and battery, and its technical characterstic is; Described electric screw is criticized and is comprised that also first luminous when the being used for output shaft work lighting device continues the second luminous lighting device with being used for, and described first lighting device and second lighting device all are electrically connected with battery.
After adopting above structure, compared with prior art, the utlity model has following advantage: for the output shaft direction provides light, make the worker under the more weak situation of surround lighting, also can see screw clearly through first lighting device, aim at smoothly, easy to operate; Through the lasting light that second lighting device sends, the assurance worker can see working environment, road conditions etc. clearly, makes electric screw criticize the function that itself has had flashlight, carries more conveniently, has also saved accommodation space.
As preferably, described first lighting device comprises LED lamp pearl, and described LED lamp pearl is arranged on the shell near output shaft one end; Described first lighting device is electrically connected with battery and is meant LED lamp pearl and motor parallel, and described first switch is controlled the on/off of LED lamp pearl simultaneously.This setting make the lighting device of winning light is provided more directly for the output shaft direction, and through LED lamp pearl and motor parallel, first switch is controlled the on/off of LED lamp pearl simultaneously; When motor running drove output shaft, LED lamp pearl was luminous, and promptly during the output shaft rotation work, LED lamp pearl is luminous; Make the lighting device of winning provide light easy to operate, need not other unlatching, saved the working time; Output shaft during rotation work, do not give out light, and saved battery electric quantity by LED lamp pearl.
As preferably, described second lighting device comprises torch LED lamp and reflection shield, and described second lighting device is arranged on the shell end face away from output shaft one end; Described second lighting device is electrically connected with battery and is meant that the positive pole of torch LED lamp links to each other with the positive pole of battery, and the negative pole of torch LED lamp links to each other with the negative pole of battery, and string has second switch on the loop of LED lamp battery.This setting makes that second Lighting Division is independent Lighting Division, can use as illuminations separately.
As improvement, described second Lighting Division also comprises the printing opacity light cover.This setting makes under the situation that does not influence illuminating effect, has guaranteed that torch LED lamp is not easy by the damage of colliding with of the hard thing in the external world.
