At this time, the movement direction of the universal wheel 18 is restricted, and a group of buttons 24 are used to control the start of the motor 7 to rotate the cutting disk 9 and perform the seam cutting work. While continuing to rotate the screw rod 3 slowly, the cutting disk 9 is indirectly fed downward to the required cutting depth. Finally, the handle 23 is used to push the whole to move horizontally, so as to realize the cutting and processing construction work of the overall road surface transverse joints.
