The utility model relates to a new spiral telescopic structure, which comprises a support, a telescopic screw, a guide and a power component. The guide component is arranged in the support, an axial guide groove is arranged in the support, the telescopic screw can be rotated in the support, and the telescopic screw can rotate and telescopic in the support by cooperating with the guide component. The power component is inserted in the axial guide groove, and the power component is driven by the telescopic screw. Connecting, the power component moves directionally in the support along with the movement of the telescopic screw, which simplifies the overall structure. The power component drives the telescopic screw to rotate directly and sets an axial guide groove in the support to make the power component move directionally in the support. When the telescopic screw moves in rotation and telescoping, there will be no movement interference, eliminating the chaos of the motion track of the telescopic screw, and the power group. The power is directly input into the telescopic screw to improve the power output efficiency and transmission efficiency. In addition, the insertion of the power components in the axial guide groove can reduce the vibration of the telescopic screw when it moves, make the whole operation stable and reduce the noise.
