[0012] As an improvement, one end of the pull spring is connected with an electric cylinder. In order to adapt to different groups of people, the handle pulling force is adjusted to low, medium and high intensity by adjusting the extension distance of the electric cylinder, so as to meet the needs of different users. The electric cylinder is installed on the side wall or the bottom of the container through a support.

[0013] The back force tensioning mechanism of the utility model, the user holds the handle with both hands, bends and stretches the arm regularly, pulls and relaxes the pull belt. When the arm completes a complete bending and stretching, the stirring blade shaft / washing wheel blade shaft can rotate multiple times, achieving the effect of fitness, and at the same time, the mixed liquid can be fully stirred, or the clothes can be washed. The adjustment of the low, medium and high intensity of the handle pulling force enables the user to experience smooth, gradual and satisfactory exercise, and is suitable for people of various ages and body types.
