Anti-overload electric screw driver

Abstract

The invention discloses an anti-overload electric screw driver. The anti-overload electric screw driver comprises a shell, a speed reducer is arranged in the shell, the input end of the speed reduceris connected with a clutch, and an input shaft of the clutch is provided with an input gear disc and an adjusting hand shank; a handle is arranged at the lower end of the shell, a motor, a switch, a power supply and a charging connector are arranged in the handle, an input shaft of the motor meshes with the input gear disc, and the motor, the switch and the charging connector are electrically connected with a power supply; and a fixing rod is arranged at the front end of the shell, a transmission rod is arranged in the fixing rod, one end of the transmission rod is connected with the output end of the speed reducer, the other end of the transmission rod is provided with an adapter, and a screw drivers bit is arranged in the adapter. According to the anti-overload electric screw driver, adjustment of the screw driver screwing torque can be achieved, the driver bit can be randomly replaced, the requirements of multiple occasions can be met, screw disassembling and assembling are convenient, and the structure is compact.

Description

technical field [0001] The invention belongs to the field of hardware tools, in particular to an overload-proof electric screwdriver. Background technique [0002] Screwdrivers are widely used in the installation and disassembly of mechanical equipment, and have become an indispensable tool in the mechanical field. With the development of science and technology, the structure of mechanical equipment is becoming more and more complex, and the manufacturing is becoming more and more refined. There are many kinds of screws used. Most of the screwdrivers are fixed or manually tightened, which is inconvenient to disassemble and assemble the screws. , the efficiency is not high, and most of the torque is not adjustable, there is a danger of causing the thread teeth to jump off, so it is necessary to develop a screwdriver that prevents overload and has high reliability when screw tightening. Contents of the invention [0003] The object of the present invention is to solve the a...
