The utility model discloses a novel locker handle limiting device, which relates to the technical field of integrated circuit testing and comprises a frame structure, a side lifting structure and a rotary locking structure. A second cam follower fixed on a rotating handle drives pull-down frames to move along the long edge of a side lifting block, the pull-down frames are rigidly connected through screws, the pull-down frames move to drive the side lifting block and a sliding block which are connected together to move together, and the pull-down frames and the testing equipment are locked through a first cam follower. After locking, the second cam follower is just located at the limiting position of the pull-down frame, the rotating handle cannot continue to rotate, and at the moment, the magnetic attraction limiting structure conducts magnetic attraction limiting on the rotating handle; therefore, the problem that after the circuit board to be tested and the test equipment are locked, a user continues to pus
