The invention discloses a torsion spring. The torsion spring comprises an energy storage assembly and a rotating assembly, wherein the energy storage assembly is in transmission fit with the rotating assembly, the energy storage assembly comprises a closed cylinder barrel and a piston rod, a piston is arranged in the cylinder barrel, the piston is in sealing fit with the inner wall of the cylinder barrel, the piston is fixedly connected with one end of the piston rod, and the other end of the piston rod penetrates through the cylinder barrel and then is fixedly connected with a rack; and the rotating assembly comprises a rotating shaft and a cylindrical gear, the cylindrical gear is fixedly arranged on the rotating shaft, and the cylindrical gear is meshed with the rack. The twisted rope winding drum assisting in winding up comprises the torsion spring, a rotating drum and a twisted rope wound on the rotating drum, wherein one end of a rotating shaft of the rotating drum is in transmission fit with a main power output device, and the other end of the rotating shaft of the rotating drum is in transmission fit with the cylindrical gear. The torsion of the torsion spring in the design is adjustable; installing and debugging are easy; and the torsion spring provides a winding-up assisting function for the twisted rope winding drum, so that the power requirement for a motor can be reduced.
