In this embodiment, the main shaft and the main shaft limit plate are welded together, and the ground cutter shaft limit plate are welded together. When the brake is switched off, the spindle rotates anticlockwise rapidly to drive the spindle limiting plate to rotate synchronously, and the spindle limiting plate collides with the limiting lock catch with huge impact force to rotate clockwise. The limiting lock catch rotates to drive the ground cutter shaft limiting plate to rotate, and the ground cutter shaft limiting plate are integrated, so that the ground cutter shaft also rotates anticlockwise. When the ground cutter shaft rotates, the energy storage spring is compressed, and the energy storage spring absorbs all impact force from the main shaft at the moment, so that the effect of absorbing vibration is achieved, the phenomenon that the insulation distance of the main shaft is shortened due to overlarge impact force is avoided, and the technical requirement is met. And the mechanical design of spacing hasp makes the resistance arm big, and its result is that energy storage spring inhales the shock effect more obvious. Finally, the limit lock catch is pulled by the interlocking hanging spring so that the limit lock catch still restores to the initial state after a series of operations.
