[0002] A road cutter is a cutting tool widely used for cutting expansion joints in roads or repairing asphalt. At present, most road cutters rely on changing the size of the cutting wheel and the operator's experience to achieve the positioning of the cutting depth when cutting roads. Some road cutters also use a rocker structure formed by a screw rod and a screw tube. The screw rod is vertically set above the saw blade. By adjusting the up and down movement of the moving wheel of the frame base, the ground distance of the cutter as a whole is changed to adjust the cutting depth;

[0003] According to the public announcement number: CN217973978U, a road cutting device for municipal engineering is disclosed. This technology discloses technical solutions such as "the rotation of the gear drives the screw to rotate, so that the screw drives the screw sleeve meshing with it to move up and down, and the screw drives the support rod to move up and down, so as to reach the position of the push plate", which has technical effects such as "the device can adjust the push plate according to the height of the user and the use environment";

[0004] However, the above scheme controls the cutting depth of the cutting knife by adjusting the length of the movable slot extending from the positioning rod. During the actual cutting operation, some road surfaces cannot be cut vertically. However, the cutting knife angle in the above scheme is fixed and cannot be adjusted according to the needs.

[0005] In order to solve the above problems, this application proposes a road surface cutting device for municipal engineering. Utility Model Content
