The lower mounting frame 1 is fixedly installed between the left and right support columns 3, and the upper mounting frame 2 is fixedly installed between the left and right sleeves 4. The lower mounting frame 1 and the upper mounting frame 2 are both hollow. Wheel axles 5 are fixedly installed on the front and rear surfaces of the support columns 3. The ends of the wheel axles 5 are rotatably connected with moving wheels 6. A placement seat 7 is fixedly installed at the bottom of the support column 3. The wheel axle 5 and the moving wheel 6 are located at the bottom end of the left support column 3, and the placement seat 7 is located on the bottom end of the right support column 3. The bottom end of the placement seat 7 and the bottom end of the moving wheel 6 are located on the same horizontal line. The arrangement of the placement seat 7 can ensure the stability of the whole when in use. A double-edged guillotine 15 is arranged inside the lower mounting frame 1, and a mounting bolt 16 is threadedly connected to the back of the lower mounting frame 1. The end of the bolt 16 protrudes to the other side of the double-edged guillotine 15, and the end of the mounting bolt 16 is threadedly connected with a mounting nut 17. The double-edged guillotine 15 is fixedly installed inside the lower mounting frame 1 by the mounting bolt 16 and the mounting nut 17. The setting of the double-edged guillotine 15 can increase its service life, and the setting of the mounting bolt 16 and the mounting nut 17 can make it easy to install and disassemble. A mounting groove 22 is provided at the bottom of the upper mounting frame 2, and a cutting guillotine 18 is slidably connected inside the mounting groove 22. A rack 19 is fixedly installed on the front of the cutting guillotine 18. The front and rear surfaces of the upper mounting frame 2 are rotatably connected with a rotating shaft 20, and a gear 21 is fixedly connected to the end of the rotating shaft 20, and a cutting handle 23 is fixedly connected to the other end of the rotating shaft 20. The rack 19 is meshed with the gear 21, and the rack 19 and the gear 21 are both symmetrically arranged in two groups in front and back. The cutting handle 23 is fixedly installed between the front and rear rotating shafts 20, and the gear 21 cooperates with the setting of the rack 19 to facilitate cutting operations.

[0025] When using the sidewalk brick cutting device, first, the device can be moved to the work site through the cutting handle 23 and the moving wheel 6, and then the placement seat 7 can be brought into contact with the ground to make the whole device stable on the spot, and then the bricks to be cut can be placed on the first platform 11 and the second platform 14, and placed on the top of the double-edged guillotine 15, and then the cutting handle 23 can be manually turned downward, and the cutting handle 23 drives the rotating shaft 20 to rotate downward, and the rotating shaft 20 drives the gear 21 to rotate, thereby prompting the rack 19 meshing with it to move downward, and driving the cutting guillotine 18 to move downward to cut the bricks. The operation is very simple and convenient. When the top of the double-edged guillotine 15 is worn to a certain extent and needs to be replaced, the mounting nut 17 and the mounting bolt 16 can be removed at this time, and then the double-edged guillotine 15 can be turned around and installed again, which greatly increases its service life. The first platform 11 can also be removed by removing the fixing screw 12, which is very convenient to use. Example
