Abstract: The control method includes determining a target operating mode in response to a target instruction in a target scenario, controlling a target antenna in the target operating mode to receive a first radiated signal at a first frequency, and transmitting a second radiated signal at a second frequency. The first frequency and the second frequency belong to a same frequency band. The target operating mode includes a plurality of different antenna operating modes. Under at least two of the antenna operating modes of the plurality of different antenna operating modes, the second radiated signal at the second frequency is transmitted at different target powers to cause transmission powers of the plurality of different operating modes to be equal to or approach a power limit of the target scenario. The target power represents a power of a radio frequency path between an antenna port of the target antenna and a transceiver.

Abstract: A method for an electric nail gun to drive the flywheel to transmit nailing energy, including boosting a start voltage of a battery so as to excite an electromagnet to work and then drive the flywheel loaded with nailing energy in a frictional manner to drive a nailing rod to hit the nail.

Abstract: A return transmission of nailing rod for electric nail gun is disclosed, comprising a pulley assembly and a return elastic component configured in a gun body frame. The pulley assembly includes a towing rope, a movable pulley that guides the towing rope. A guiding holder is provided for pivoting the movable pulley. When the nailing rod moves downward along a nailing stroke to shoot the nail, the towing rope can tow the movable pulley and drive the guiding holder to move an action stroke in a way to store the elastic potential energy of the return elastic component. After nailing, the return elastic component will drive the guiding holder in a way to release the elastic potential energy, so that the guiding holder can move along the action stroke back to its original position, and the guiding holder will tow the towing rope through the movable pulley, so as to drive the nailing rod to move along the nailing stroke back to its original position.
