The invention relates to the technical field of single-point impact wear test devices, and provides a simple pendulum type high-speed impact scratch test device which comprises a supporting frame, a simple pendulum unit, an energy supply unit and a hammer blocking unit are arranged on the supporting frame, and the simple pendulum unit makes contact with the energy supply unit to complete scratch; after the simple pendulum unit is in contact with the energy supply unit, the simple pendulum unit is in contact with the hammer stopping unit and is stopped by the hammer stopping unit from continuously swinging; in the process that the simple pendulum unit makes contact with the energy supply unit, scratching is achieved. After the simple pendulum unit makes contact with the energy supply unit, the simple pendulum unit makes contact with the hammer blocking unit and is prevented from continuously swinging by the hammer blocking unit, and secondary scratches are prevented from being generated on the surface, making
