A manual electric integrated screwdriver

Abstract

A manual electric integrated screwdriver, comprising: a screwdriver part, a grip mechanism, a pretightening force boosting mechanism, a state switching mechanism, and an electric driving mechanism. Mechanism connection, the screwdriver part is installed inside the pre-tightening force holding mechanism; the state switching mechanism is slidably installed outside the screwdriver part; the push ring is controlled by manually controlling the push button, and then the external block and the inner block are controlled respectively to match the screwdriver part and the inner block. The pre-tightening force holding mechanism is stuck to realize the switch between manual and electric; the external block and the inner block of the state switching mechanism are in contact with the pre-tightening mechanism slot and the slot respectively, and the screwdriver is divided into electric Working, manual working and manual working with pre-tightening force, the three states can be switched, so that the screwdriver can be applied to different needs.

Description

technical field [0001] The invention relates to the technical field of screwdrivers, in particular to a manual electric integrated screwdriver. Background technique [0002] A screwdriver is a tool commonly used in households and the electrical industry. Because the manual screwdriver is laborious to screw, people with small hands cannot unscrew it. Therefore, an electric screwdriver was invented on the basis of the screwdriver. However, due to the large size of the electric screwdriver, it is inconvenient to carry. , and it cannot work without electricity; [0003] For example, the Chinese invention patent of Patent No. 2014106958796 discloses a screwdriver, which assists in tightening and loosening screws by setting a torsion spring in the middle of the handle and replacing torsion springs in different directions. It saves effort, but because the torsion spring needs to be replaced for tightening and unscrewing, the operation is complicated. The Chinese invention patent o...

[0002] A screwdriver is a tool commonly used in households and the electrical industry. Because the manual screwdriver is laborious to screw, people with small hands cannot unscrew it. Therefore, an electric screwdriver was invented on the basis of the screwdriver. However, due to the large size of the electric screwdriver, it is inconvenient to carry. , and it cannot work without electricity;

[0003] For example, the Chinese invention patent of Patent No. 2014106958796 discloses a screwdriver, which assists in tightening and loosening screws by setting a torsion spring in the middle of the handle and replacing torsion springs in different directions. It saves effort, but because the torsion spring needs to be replaced for tightening and unscrewing, the operation is complicated. The Chinese invention patent of Patent No.: 2018113532692 discloses an electric screwdriver, including a housing; the driving part provides working power for the electric screwdriver; The transmission part, the force input end of the transmission part is coaxially connected with the driving end of the driving part; the torque adjustment part is used to adjust the output torque of the electric screwdriver, the torque input end of the torque adjustment part and the The force output end of the transmission part is connected coaxially; and the execution part is installed on the front end of the housing. Because it uses electric drive, when the battery is out of power, the screwdriver cannot work. The size of the force to determine whether the screw is tightened, but the electric screwdriver can not achieve
