Figure 3 Then, with the cooperation of the first motor 31 and the first lead screw 32, the cutting blade 7 moves downward to cut the road at a convenient location, and then feeds by pushing the base 1;

[0046] 2) After the work is completed, with the cooperation of the fourth motor 57, the second motor 43, and the first motor 31, the device is restored to the storage state (see...). Figure 1 );

[0047] 3) The water inside the water tank 2 reaches the nozzle 9 through the hose, fixed pipe 92, and connecting pipe 91, and then sprays onto the cutting blade 7 to cool it down.

[0048] Compared with the prior art, the present invention has the following advantages:
