[0026] Referring to Figures 2-4As shown, a connecting ring 13 is fixedly provided on one side of the pre-cutting blade 1. Multiple connecting holes 14 are provided on the surface of the connecting ring 13. A second bolt 15 is threaded into the interior of each connecting hole 14. A stabilizing ring 16 is threaded into the exterior of the second bolt 15. A threaded cylinder 17 is fixedly provided at one end of the stabilizing ring 16. By rotating the second bolt 15 in the opposite direction, the second bolt 15 can be pulled out from the inside of the stabilizing ring 16 and the connecting hole 14, and the pre-cutting blade 1 can be removed. This ensures the stability of the connection and effectively controls the circumferential position of the pre-cutting blade 1 during rotation, ensuring cutting accuracy. Furthermore, by rotating the threaded cylinder 17 in the opposite direction, the threaded cylinder 17 can be removed from the surface of the threaded rod 20, allowing different types of pre-cutting blades 1 to be installed on the threaded rod 20 for easy replacement and installation.

[0027] Reference Figures 4-6 As shown, a motor 18 is installed on one side of the pre-cutting blade body 1. A rotating shaft 19 is fixedly installed at the output end of the motor 18. A threaded rod 20 is fixedly installed on one side of the rotating shaft 19. A threaded cylinder 17 is threadedly connected to the threaded rod 20. The blade 2 is made of cemented carbide, and a wear-resistant layer 21 is fixedly installed on the surface of the blade 2. The wear-resistant layer 21 is made of titanium nitride. When the motor 18 is started, it drives the rotating shaft 19 and the threaded rod 20 to rotate. The threaded rod 20 drives the threaded cylinder 17 to rotate. Since the threaded connection direction between the threaded rod 20 and the threaded cylinder 17 is opposite to the direction of rotation of the threaded rod 20 driven by the motor 18, the threaded cylinder 17 is prevented from falling off during rotation. This causes the threaded cylinder 17 to drive the pre-cutting blade body 1 to rotate, and the pre-cutting blade body 1 drives the blade 2 to rotate at high speed. The blade 2, made of cemented carbide, is used to cut the floor material by rotating and contacting it with the sharp edge of the blade. The blade 2 has a wear-resistant layer 21 made of titanium nitride, which provides good hardness, wear resistance, and heat resistance. This ensures the blade is sharp while withstanding a certain cutting force, preventing excessive wear and extending the service life of the blade 2. This initial cutting of the floor material breaks down larger floorboards into smaller ones, making the material easier to process later. At the same time, the rotation of the pre-cutting blade 1 also drives the crushing pre-cutting blade 6 to rotate at high speed, further crushing the material into small particles or fragments that meet specific requirements. The operation is convenient and quick.
