[0021] like Figure 1 , Figure 3 and Figure 4 As shown, a shell 3 is provided at the upper end of the work surface 1, and a multi-section hydraulic cylinder 4 is penetrated through the upper wall of the shell 3, a deflation component 5 is provided at the lower end of the multi-section hydraulic cylinder 4, and telescopic components 6 are provided on the left and right sides of the deflation component 5, and a cutting machine head 7 is installed at the lower end of the telescopic component 6.

[0022] like Figure 4As shown, the deflation component 5 includes a connecting pipe 501 and a deflation pipe 502, and the lower end of the connecting pipe 501 is connected to the deflation pipe 502, and the deflation component 5 also includes a hemispherical valve core 503, a spring 504, a square lifting block 505, a second threaded rod 506, a second bearing 507 and a second rotating handle 508, and the hemispherical valve core 503 is installed inside the deflation pipe 502, the lower end of the hemispherical valve core 503 is provided with a spring 504, and the lower end of the spring 504 is provided with a square lifting block 505, and the inside of the square lifting block 505 is provided with A second threaded rod 506 is provided, and a second rotating handle 508 is provided at the lower end of the second threaded rod 506. A second bearing 507 is embedded in the middle of the lower end of the air release pipe 502. The elastic structure formed by the hemispherical valve core 503 through the spring 504 and the square lifting block 505 can make the hemispherical valve core 503 open after being subjected to a certain degree of force, thereby protecting the internal pressure of the telescopic chamber 601 through the connecting pipe 501 and the air release pipe 502, avoiding excessive pressurization that leads to increased wear between the cutting head 7 and the material, and reducing the service life of the cutting head 7.

[0023] like Figure 3 As shown, the telescopic component 6 includes a telescopic chamber 601 and a one-way valve 602, and the one-way valve 602 is installed at the upper end of the telescopic chamber 601. The telescopic component 6 also includes a piston 603 and a telescopic rod 604, and the piston 603 is installed inside the telescopic chamber 601, and the lower end of the piston 603 is connected to the telescopic rod 604. The one-way valve 602 can replenish the air pressure inside the telescopic chamber 601 when the equipment stops working, so as to reset the equipment, and the cutting head 7 is buffered by the telescopic structure formed by the telescopic rod 604 through the piston 603 and the telescopic chamber 601.

[0024] Working principle: When using the cutting machine with a limiting structure, first place the material on the work surface 1, rotate the first rotating handle 205 to drive the first threaded rod 204 that constitutes a rotating structure between the first bearing 203 and the limiting baffle 201 to rotate, thereby relying on the threaded connection between the first threaded rod 204 and the threaded sleeve 206 to move the limiting baffle 201, thereby moving the limiting baffle 201 to the position of the required cutting material length, and the sliding rod 202 can guide the limiting baffle 201 to prevent the limiting baffle 201 from rotating with the first threaded rod 204. When the position adjustment of the limiting baffle 201 is completed, the staff only needs to press the material firmly against the limiting baffle 201, and then open the multi-section hydraulic cylinder 4 to drive the cutting head 7 to descend and cut the material. During the cutting process, the telescopic rod 604 is relied on to pass between the piston 603 and the telescopic chamber 601. The telescopic structure formed can buffer the cutting head 7 to avoid damage caused by instantaneous pressurization. If the multi-section hydraulic cylinder 4 applies too much pressure to the cutting head 7, the air pressure inside the telescopic chamber 601 will be greater than the elastic force of the spring 504 borne by the hemispherical valve core 503, thereby pushing the hemispherical valve core 503 open and releasing the pressure in the telescopic chamber 601 through the connecting pipe 501 and the air release pipe 502, thereby protecting the cutting head 7. The staff can also rotate the second rotating handle 508 to drive the second threaded rod 506 that forms a rotating structure between the second bearing 507 and the air release pipe 502 to rotate, thereby adjusting the position of the square lifting block 505, and then adjusting the elastic force applied by the spring 504 to the hemispherical valve core 503, and controlling the force of the cutting head 7 when it needs to be depressurized. The one-way valve 602 can replenish the air pressure inside the telescopic chamber 601 when the equipment stops working to reset the equipment.
