In the process of installing the torque multiplier, an operator makes the output end of the torque multiplier face the center of the first fixing frame 5, wherein the lower end of the torque multiplier is firstly contacted with the upper surface of the rotating ring 174, meanwhile, the reaction force arm of the torque multiplier is located in the limit groove of the limit shell 3, then the operator is quickly connected with the input end of the torque multiplier by rotating the torque wrench 10, after the torque multiplier is placed, the torque multiplier extrudes the rotating ring 174 and the sliding ring 172 to move downwards together under the action of the gravity of the torque multiplier until the lower surface of the torque multiplier is contacted with the upper surface of the first fixing frame 5.
