A high twisting ratchet wrench comprises a wrench body, a ratchet body, an adjusting means; two brake blocks, and two elastomers. The ratchet body, brake blocks and elastomers are installed in a head at one end of the wrench body. Each brake block is installed within one of two actuating grooves in inner edges of the head. An outer peripheral surface of each brake block has a plurality of buckling teeth. The head of the wrench body has two actuating grooves for receiving the brake blocks. Each actuating groove has a rectangular shape. A cross sectional view of each brake block has a rectangular shape. Thus, the area of the buckling teeth is increased so as to increase a contact area of the brake blocks and the ratchet body and thus the twisting force of the wrench body applied to an object locating within the ratchet body is enhanced.
