The labor-saving tensioner comprises a tensioner body and a main handle, the main handle is arranged at the lower end of the tensioner body, sliding grooves are formed in the front end and the rear end of the main handle, brake pads are arranged in the sliding grooves in a sliding mode, and the brake pads are connected with the main handle through telescopic mechanisms. A transmission mechanism and an adjusting mechanism are arranged in the main handle, and the right end of the main handle is connected with the auxiliary handle through the adjusting mechanism. The telescopic mechanism is arranged for stretching and retracting, the structure that the spring is exposed outside is changed, the service life of the spring is prolonged, the hand clamping phenomenon caused by contraction of the spring in the using process is avoided, in addition, the two adjusting mechanisms are controlled through the transmission mechanism, the length between the main handle and the auxiliary handle can be changed through the two a
