Abstract

The invention provides a manual and electric integrated screwdriver. The manual and electric integrated screwdriver comprises a screwdriver portion, a gripper mechanism, a pretightening force applyingmechanism, a state switching mechanism and an electric drive mechanism. The electric drive mechanism is mounted in the gripper mechanism, the electric drive mechanism is connected with the pretightening force applying mechanism, and the screwdriver portion is mounted in the pretightening force applying mechanism. The state switching mechanism is slidingly mounted on the outer side of the screwdriver portion. A push ring is controlled by manually controlling a push button, then outer clamping blocks and inner clamping blocks are controlled to be clamped with the screwdriver portion and the pretightening force applying mechanism correspondingly, and therefore manual operation and electric operation are switched. The outer clamping blocks and the inner clamping blocks of the state switchingmechanism are clamped with clamping grooves of the pretightening force applying mechanism and clamping grooves in a contact manner or are not in contact with the clamping grooves of the pretighteningforce applying mechanism and the clamping grooves correspondingly, the screwdriver is switched between the three states of electric work, manual work and manual work under pretightening force, and therefore the screwdriver can meet different requirements.
