The invention discloses an angle-adjustable retracting and stretching mechanism of an angle-adjustable landing light. The angle-adjustable retracting and stretching mechanism comprises a shell, a sector gear component, a motor reducer, a swinging arm component, a stretching in-place switch and a retracting in-place switch. The sector gear component is fixed to the shell through a main shaft to be connected with the shell in a rotating mode and is provided with a load fixing end. An output gear of the motor reducer is meshed with the sector gear component to drive the sector gear component to rotate. The swinging arm component comprises an upper swinging arm and a lower swinging arm, the upper swinging arm and the lower swinging arm are driven by the sector gear component to rotate around the main shaft, the upper swinging arm is provided with a stretching in-place contact piece, the lower swinging arm is provided with a retracting in-place contact piece, and an adjusting screw is installed on the lower swinging arm and abuts against the side wall of the upper swinging arm. The stretching in-place switch is fixed to the shell and matched with the stretching in-place contact piece of the upper swinging arm. The retracting in-place switch is fixed to the shell and matched with the retracting in-place contact piece of the lower swinging arm. The angle-adjustable retracting and stretching mechanism has the advantages of being high in reliability, easy to maintain, small in size and light in weight, enabling the complete-stretching angle to be conveniently adjusted and the like.
