Then, the um carrier is supported by the pendulum releasing component. Subsequently, the first driving mechanism of the pendulum lifting component is reset, the rotary block of the pendulum releasing component is turned toward a side away from the pendulum carrier to cancel the support to the pendulum r, and the pendulum impacts the parts on the box due to its own y. In this way, the strength of the box component is tested. In the present ion, the automatic operation of the pendulum can be realized. It is only necessary to manually place and fix a box component.
