Abstract
Disclosed is a torsion rotating device with a torsional braid for controlling an electric screw driver. The device mainly comprises the torsional braid and is characterized that a motor, the torsional braid and lithium batteries are arranged in a casing, a switch and a recharge stand are arranged on the lower side of the casing, one end of the torsional braid is connected with the motor in a rotating mode, and the other end of the torsional braid is hitched to the screw driver. The motor rotates to the left and drives the torsional braid to rotate when the left side of the switch is pressed, and the screw driver looses a screw when the corkscrew force of the torsional braid exceeds the fastening force of the screw. The motor rotates to the right and drives the torsional braid to rotate when the right side of the switch is pressed, the corkscrew force of the torsional braid increases synchronously along with the increase of the fastening force of the screw, therefore the screw is fastened and automatic torsion regulation of the screw driver through the torsional braid is achieved.
Description
Technical field
Being connected transition apparatus between the motor that the present invention relates to a kind of electric tool and the bottle opener, is a kind of torsion whirligig of torsion band control electric screw driver concretely.
Background technology
At present, torque spanner all has the by-pass cock of a torque magnitude, and the size through the adjustment switch is to realize getting rid of the adjusting of an outputting torsion; This control method is simple, but torsion divides gear, selects screw low to twist motionless; Selected height, screw is twisted into two parts, and has inconvenience to practical operation.
Summary of the invention
The object of the present invention is to provide a kind of torsion whirligig of torsion band control electric screw driver, have the function of automatic adjusting bottle opener torsion output.
The present invention realizes with following technical scheme: the torsion whirligig of this a kind of torsion band control electric screw driver mainly is made up of a torsion band; It is characterized in that: motor, torsion band, lithium battery are installed in the inside of shell; A switch and a cradle are installed in the below of shell; One end of torsion band is rotatably connected with motor, and the other end entangles bottle opener.Turn left in the left side of Push switch, motor, the rotation of driven by motor torsion band, and when the spiral power of torsion band surpasses the fastening force of screw, bottle opener becomes flexible screw; The right of Push switch, motor is turned right, the rotation of driven by motor torsion band, along with the increase of screw fastening force, the spiral power of torsion band is also in synchronous increase, and screw is able to fastening, has realized the function that the torsion band is regulated bottle opener torsion automatically.
The invention has the beneficial effects as follows: adjust bottle opener torsion automatically by the torsion band, with the function of the easy removal that realizes screw.
Description of drawings
Fig. 1 is the structural map of the torsion whirligig of a kind of torsion band control of the present invention electric screw driver in electric wrench inside.
1. shells among the figure, 2. lithium battery, 3. torsion band, 4. bottle opener, 5. motor, 6. cradle, 7. switch.
The specific embodiment
Fig. 1 is the structural map of the torsion whirligig of a kind of torsion band control of the present invention electric screw driver in electric wrench inside; Its structure is made up of shell 1, torsion band 3, motor 5, lithium battery 2, switch 7, cradle 6, bottle opener 4; In Fig. 1: motor 3, torsion band 3, lithium battery 2 are installed in the inside of shell 1; Torsion band 3 and motor 5 are for being rotatably connected, and a switch 5 and a cradle 6 are installed in the below of shell 1, and bottle opener 4 is enclosed within on the torsion band 3.Except torsion band 3, all the other are the standard configuration part of electric screw driver.
Described switch 7 is a double control switch.
Described torsion band 3 is divided into: just changeing band and the negative band that changes, just changeing band and be used for holding screw, the negative band that changes is used for dismantling screw.
Described just the commentaries on classics is with its torsion bar for turning clockwise.
Described negative commentaries on classics is with its torsion bar for being rotated counterclockwise.
