Abstract
The utility model relates to an electric screw driver. According to the electric screw driver, when the left side of a switch is pressed, a motor is rotated towards the left, when the rotating speed of the motor reaches a binding force of a throwing head, a rotating head is driven by the throwing head to rotate towards left, and a screw is loosened; when the right side of the switch is pressed, the motor is rotated towards the right, when the rotating speed of the motor reaches the binding force of the throwing head, the rotating head is driven by the throwing head to rotate towards right, and the screw is fastened, so that disassembling and fastening functions of the screw are realized; and meanwhile, when the electric energy of a battery is reduced to a certain degree, the electric energy of the battery can be supplied directly via a mains supply. The electric screw driver has the advantage of functions convenient for disassembling small screws.
Description
Technical field
The utility model relates to a kind of extracting tool that keeps in repair usefulness, is a kind of electric screw driver concretely.
Background technology
At present, most maintenance master worker is in knockout screw, and is all also using manual bottle opener, inconsistent because of the strength that screw is fastening, causes time waste to maintenance.
Summary of the invention
The purpose of the utility model is to provide a kind of electric tool.
The utility model is realized with following technical scheme: this electric screw driver mainly by shell, get rid of head, motor, lithium battery, switch, cradle, bottle opener and form; It is characterized in that: in the inside of shell motor is installed, gets rid of head, lithium battery; Getting rid of head flexibly connects for rotating with motor; A switch and a cradle are installed in the below of shell, and bottle opener is enclosed within and gets rid of on the head.The left side of Push switch, motor turns left, and when rotating speed of motor reaches the adhesion of getting rid of head, gets rid of head and drives rotary head to anticlockwise, and screw is loosening; The right of Push switch, motor is turned right, when rotating speed of motor reaches the adhesion of getting rid of head; Get rid of head and drive rotary head to right rotation; Screw is fastening, realizes the dismounting and the fastening function of screw, simultaneously; When the electric energy of battery drops to a certain degree, can directly replenish by the electric energy of civil power to battery.
The beneficial effect of the utility model is: the function with primary screw for convenience detach.
