Improvement of problems in application of spring motor

The invention aiming at the problems of a reciprocal swinging type spring motor and an electric reciprocal motion device in connection and application, discloses four novel structure designs. Firstly, a lead-out connection mode of a rotor coil lead inside the spring motor is improved; secondly, an elastic spring device is arranged at the opening end of a connecting shaft; thirdly, a round flat sealing ring on a motor shaft is designed into a round funnel-shaped rubber sealing ring; and fourthly, a rectangular structure with four closed edges is changed into a mode that three frames are fixed structures and one frame is a mobile structure. By means of the methods and the structures, the spring motor is more reasonable in structure, connecting assembly and application, and more convenient, safer and more reliable to use.
