c. in the rotation process of the output end of the motor (4), the transmission shaft (204) is driven to synchronously rotate through the transmission belt (206), the gear (205) at the bottom end of the transmission shaft (204) drives the gear ring (702) at the outer end part of the cutter (701) to rotate, and then the cutter (701) at the outer side of the cutting shaft (7) is driven to keep a rotating state, so that the cutter (701) extending downwards out of the frame (1) cuts the bridge expansion joint, and the cutter (701), the spray head (303) and the brush head (505) are ensured to synchronously start and stop working.
