The invention discloses a tool handle scrap entrainment detection device calibrator which comprises a calibration rack, a support arm, a lever, a fixing frame, a mounting seat, a power arm hinge connecting block, a resistance arm hinge connecting block, a top moving electromagnet, a top fixing electromagnet, a top fixing seat and a spring; the support arm is arranged on the calibration rack, the upper end of the support arm is hinged to the middle of the lever, the front end of the lever is hinged to the resistance arm hinge connecting block, and the rear end of the lever is hinged to the power arm hinge connecting block; and the top fixing seat is arranged on the top of the calibration rack. The tool handle scrap entrainment detection device calibrator has the beneficial effects that theelectromagnet is used as a power output unit, power output is strong, calibration work to a scrap entrainment detection device is completed under the condition that a machining center motorized spindle broach mechanism is not used, when scrap entrainment detection devices produced in batch are calibrated, tedious installation steps are reduced, calibration time is shortened, the production cost isreduced, and the calibration work efficiency is greatly improved.
