The invention discloses a lever block with a load limiting protection function and a method thereof, and belongs to the technical field of lever blocks. Comprising a shell; a transmission shaft is rotationally mounted in the shell through a bearing; the side, close to the load limiting wrench, of the middle of the transmission shaft is provided with an anti-falling assembly. An adjustable transmission mechanism is mounted in the left side of the transmission shaft and the left side of the shell; the loading chain wheel is rotationally mounted in the middle of the transmission shaft; the adjustable transmission mechanism comprises a middle shaft assembly and a variable-speed transmission assembly, the middle shaft assembly is installed in the left side of the shell and the left side of the transmission shaft, and the variable-speed transmission assembly is installed in the left side of the shell; the variable-speed transmission assembly is fixedly connected with the loading chain wheel; the adjusting assembly is installed outside the variable speed transmission assembly and the shell. By means of the mode, the variable-speed transmission assembly is adjusted through the adjusting assembly, the transmission ratio between the variable-speed transmission assembly and the middle shaft assembly is changed, and therefore the mechanism can adapt to objects of different weights.
