Abstract
The utility model discloses a carry high torsion's electric screwdriver changeover mechanism, including electric screwdriver, gear shell, first pinion, first gear wheel, the second pinion, second largest gear, the chuck, connecting rod and fixed head, first pinion is connected with electric screwdriver's chuck, first pinion is connected with first gear wheel meshing, first gear wheel and second pinion series connection, the second pinion is connected with second largest gear meshing, second largest gear is connected with the chuck, first pinion, first gear wheel, second pinion and second largest gear all are located gear shell, gear shell passes through the connecting rod and is connected with the fixed head, the fixed head is connected with electric screwdriver's handle. Compared with the prior art, the utility model discloses a four gear reduction gearss, improvement electric screwdriver's that simultaneously can be great torsion sets up the rotation that the connecting rod can prevent gear shell, and convenient to use has the value of popularization and application.
Description
Technical field
This utility model relates to a kind of electric screw driver auxiliary device, particularly relates to a kind of electric screw driver changeover mechanism improving torsion.
Background technology
Electric screw driver is as mechanical part, and normal work be unable to do without electric screwdriver power supply, and electric screwdriver power supply provides energy and relevant control function for electric screw driver.Drive the rotation of motor.Owing to the parameter of electric screw driver motor is different, in the case of electric screwdriver power supply output Same Efficieney, rotating speed can be different.But the torsion of electric screw driver of the prior art is inadequate, relatively elaborate when rotating more dead bolt, accordingly, there exist room for improvement.
Utility model content
The purpose of this utility model is that provides a kind of electric screw driver changeover mechanism improving torsion to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
This utility model includes electric screw driver, gear housing, first little gear, first gear wheel, two pinion, second largest gear, chuck, connecting rod and fixing head, described first little gear is connected with the chuck of described electric screw driver, described first little gear is ratcheting with described first gear wheel to be connected, described first gear wheel is connected in series with described two pinion, described two pinion is connected with described second largest gear mesh, described second largest gear is connected with described chuck, described first little gear, described first gear wheel, described two pinion and described second largest gear are respectively positioned in described gear housing, described gear housing is connected with fixing head by connecting rod, described fixing head is connected with the handle of described electric screw driver.
Further, one end of described connecting rod is connected with described gear housing by first connecting rod rotating shaft, and the second end of described connecting rod is connected with described fixing head by second connecting rod rotating shaft.
The beneficial effects of the utility model are:
This utility model is a kind of electric screw driver changeover mechanism improving torsion, compared with prior art, this utility model is by four gear composition reducing gears, the torsion of raising electric screw driver that simultaneously can be bigger, connecting rod is set and is prevented from the rotation of gear housing, easy to use, there is the value of popularization and application.
