By providing the reinforcement plate 13, the overall strength of the positioning plate 82 is improved to avoid bending.

[0036] The working principle and use process of the utility model are as follows: when the user needs to hold the handle 2 to transmit the torque increaser body 1, the user first holds the handle 2, and then pushes the clamping plate 4 to the right, and then uses the tension of the tension spring 6 to pull the connecting plate 5 to move inward, and then the connecting plate 5 drives the clamping plate 4 to move inward, so that the clamping plate 4 clamps the hand holding the torque increaser body 1, thereby improving the stability of the user when holding the handle 2 to apply force, and in the process of the clamping plate 4 clamping the user's hand, the sliding cooperation of the limiting rod 72 and the limiting hole 71 can be used to limit the clamping plate 4 up and down, so as to avoid the situation that the clamping plate 4 deviates when clamping the user's hand and cannot be used corresponding to the user's hand, and then the limiting plate 73 can be used to limit the limiting rod 72 The clamping plate 4 is clamped inwardly by the user's hand by using the handle 2 movably connected to the clamping plate 4 through the movable frame 3. The user can move the clamping plate 4 to the left, and then drive the corresponding positioning rod 81 to be inserted into the corresponding positioning plate 82.
