The invention discloses a single-cylinder synchronous telescopic seven-section arm frame which comprises an arm body, the arm body is seven sections, the arm body comprises a first section arm, a second section arm, a third section arm, a fourth section arm, a fifth section arm, a sixth section arm and a seventh section arm which are sequentially overlapped and sleeved, a telescopic oil cylinder is arranged in the arm body, a cylinder rod of the telescopic oil cylinder is hinged to the arm tail of the first section arm, and a cylinder rod of the telescopic oil cylinder is hinged to the arm tail of the seventh section arm. The telescopic oil cylinder is arranged on the arm body, the end portion of a cylinder barrel, close to the cylinder rod side, of the telescopic oil cylinder is hinged to the arm tail of the two-section arm, an extending inhaul cable, a recycling inhaul cable and inhaul cable pulleys are arranged on the arm body, the inhaul cable pulleys comprise the extending inhaul cable pulley and the recycling inhaul cable pulley, and the two-section arm is controlled to stretch out and draw back through stretching out and drawing back of a lever of the telescopic oil cylinder. And the arm body is driven to stretch out and draw back synchronously in cooperation with the stretching-out inhaul cable, the retracting inhaul cable and the inhaul cable pulley. The characteristics that the overall layout of the arm body is compact and the overall dimension is small are achieved, and under the constraint condition of the same overall dimension, the longer full-extending arm length and the lighter self-weight parameter are achieved.
