[0025] The utility model provides Figure 1-3 A road cutting device for traffic engineering shown in the figure includes a U-shaped plate 1 and a road 2. The U-shaped plate 1 is placed on the upper surface of the road 2. Both ends of the U-shaped plate 1 are provided with fixing mechanisms. The U-shaped plate 1 is fixed to the road 2 through the two fixing mechanisms. Two mounting plates 3 are fixedly connected to the upper surface of the U-shaped plate 1. Two sliding rods 4 are fixedly connected between the two mounting plates 3. Slide blocks 5 are slidably sleeved on the rod walls of the two sliding rods 4. A first mounting frame 6 is fixedly connected between the two slide blocks 5. A through hole is opened on the upper surface of the first mounting frame 6. A connecting rod 7 is slidably arranged inside the through hole. A cutting machine 8 is fixedly connected to the lower end of the connecting rod 7. A rebound mechanism is provided on the upper surface of the first mounting frame 6. The rebound mechanism matches the cutting machine 8. A cutting groove is opened on the upper surface of the U-shaped plate 1. The cutting groove matches the cutting machine 8.

[0026] When using the device, the U-shaped plate 1 is first fixed on the road 2 by two fixing mechanisms, and then the cutter 8 is started, and then the cutter is pressed down and pushed to cut the road. Since the U-shaped plate 1 is fixed at this time, the seam cut by the cutter 8 is a straight line.

[0027] In order to fix the U-shaped plate 1, Figure 1-3 As shown, the fixing mechanism includes two screw rods 9, two pressure plates 10 and two knobs 11. Internal threaded holes are opened on both sides of the U-shaped plate 1. The two screw rods 9 are respectively threadedly sleeved in the corresponding internal threaded holes. The two pressure plates 10 are respectively rotatably connected to the ends of the two screw rods 9 that are close to each other, and the two knobs 11 are respectively fixedly connected to the ends of the corresponding screw rods 9 that are away from the pressure plates 10.

[0028] Place the U-shaped plate 1 on the upper surface of the road 2, then rotate the two knobs 11 to rotate the two screw rods 9, and then drive the two pressing plates 10 to press the two sides of the road 2, so that the U-shaped plate 1 can be fixed.

[0029] And in order to make the cutting machine 8 resetting, as Figure 1-3 As shown, the rebound mechanism includes two limit rods 12, two springs 13 and two blocks 14. The two limit rods 12 are symmetrically fixedly connected to the upper surface of the first cutting machine 8.

The two blocks 14 are respectively fixedly connected to the upper ends of the corresponding limit rods 12, and the two springs 13 are respectively slidably sleeved on the rod walls of the corresponding limit rods 12.

[0030] When the cutter 8 moves downward, the two stoppers 14 respectively press the corresponding springs 13 , and then the cutter 8 can be reset after working through the resilience of the two springs 13 .

[0031] In order to facilitate the movement of the device, Figure 1-3 As shown, a plurality of mounting holes are provided on the upper surface of the U-shaped plate 1, a second mounting frame 15 is fixedly embedded inside each mounting hole, a cylinder 16 is fixedly connected to the upper surface inside each second mounting frame 15, and a universal wheel 17 is fixedly connected to the output end of each cylinder 16.

[0032] Simultaneously, each cylinder 16 is activated, and the U-shaped plate 1 can be moved up subsequently, thereby facilitating the movement of the device.

[0033] Finally, in order to facilitate the staff operation, Figure 1-3 As shown, a handle 18 is fixedly connected to the upper surface of the connecting rod 7 .

[0034] The handle 18 can be used to facilitate the operator to hold the device, thereby making the operation more convenient.
