[0038] Please refer to the fixing mechanism 5 in particular. The disassembly mechanism 3 includes a fixing block 301 fixedly connected to the output shaft end of the mounting plate 601. A plurality of fixing rods 302 are fixedly connected to a side of the fixing block 301 away from the motor 602. A threaded sleeve 303 is also fixedly embedded on a side of the fixing block 301 away from the motor 602. The internal threads of the threaded sleeve 303 are connected to bolts 304. A cutting blade 603 is commonly sleeved on the surface of the plurality of fixing rods 302 and fixed by threaded cooperation of the bolts 304 and the threaded sleeve 303.

[0039] Please refer to Figure 5 The fixing rod 302 fixed on the fixing block 301 can be adapted to the reserved mounting hole on the cutting blade 603, thereby limiting the cutting blade 603, so that the cutting blade 603 cannot rotate on the fixing block 301, thereby limiting the cutting blade 603. By tightening the bolt 304 in the threaded sleeve 303, the cutting blade 603 can be further limited, thereby improving the firmness of the fixing of the cutting blade 603.

[0040] Please refer to Figure 6 The cutting mechanism 6 also includes two reinforcing ribs 604 fixedly connected to the left and right sides of the mounting plate 601. The two reinforcing ribs 604 are fixedly connected to the lifting plate 203 on one side thereof. A protective shell 605 is fixedly connected to the left side of the mounting plate 601. The provision of the reinforcing ribs 604 can increase the structural strength of the device, increase the strength and rigidity of the mounting plate 601, and the provision of the protective shell 605 can effectively protect the staff and equipment from danger and accidental injury.

The diameter of the gasket 305 is equal to the diameter of the fixing block 301 . The gasket 305 can prevent the cutting blade 603 from loosening, thereby ensuring the safety of the device.

[0042] Please refer to Figure 2 The lifting mechanism 2 includes a U-shaped mounting frame 201 fixed on the top surface of the workbench 101, and a servo electric cylinder 202 is fixedly installed on the top surface of the U-shaped mounting frame 201.

The left side of the front side of the lifting plate 203 is fixedly connected to the mounting plate 601.

[0043] The servo electric cylinder 202 can be installed and fixed by the U-shaped mounting frame 201. The activation of the servo electric cylinder 202 will drive the lifting plate 203 to move up and down, and then the lifting plate 203 drives the mounting plate 601, the motor 602 and the cutting blade 603 to move up and down to achieve the cutting of the pipe.

[0044] Please refer to Figure 2 Two grooves 204 are provided on the lifting plate 203, and the inner contour of the grooves 204 is square. An upper knife groove 207 is also provided on the front of the lifting plate 203. Two limit holes 205 are provided on the lifting plate 203. Limit rods 206 are slidably contacted in the two limit holes 205. The two ends of the two limit rods 206 are fixedly connected to the top surface of the workbench 101 and the top wall of the U-shaped mounting frame 201 respectively.

[0045] Providing a groove 204 on the lifting plate 203 can reduce the weight of the lifting plate 203 and reduce costs. Providing an upper knife groove 207 can prevent the lifting plate 203 from affecting the working stroke of the cutting blade 603. When the servo electric cylinder 202 drives the lifting plate 203 to move up and down, it will also move up and down on the limit rod 206 through two limit holes 205, thereby ensuring the stability of the lifting and lowering of the lifting plate 203.

[0046] Please refer to Figure 2 The left and right sides of the front of the U-shaped mounting frame 201 are both provided with stabilizing components 4 for limiting the lifting plate 203. The stabilizing components 4 include a slide 401 fixedly connected to the side of the lifting plate 203. A slide column 402 is fixedly connected to the front of the U-shaped mounting frame 201.

The lifting plate 203 can be further limited by the coordinated setting of the slide 401 and the slide column 402, so that the movement of the lifting plate 203 is more stable.

[0047] Please refer to Figure 3 A fixing mechanism 5 is also provided at the left and right ends of the top surface of the support component 1. The fixing mechanism 5 includes a U-shaped bracket 501 fixedly connected to the top surface of the support component 1. A threaded hole 506 is opened on the top surface of the U-shaped bracket 501. A threaded rod 502 is threadedly connected to the threaded hole 506. The lower end of the threaded rod 502 is rotatably connected to an arc-shaped clamping plate 503. Rotating the threaded rod 502 can drive the arc-shaped clamping plate 503 to rise and fall, thereby fixing the pipe.

[0048] Please refer to Figure 3 The top surface of the arc-shaped splint 503 is fixedly connected to two symmetrical sliding rods 504. The upper ends of the two sliding rods 504 penetrate the top surface of the U-shaped bracket 501 and extend to the top of the U-shaped bracket 501. The upper end of the threaded rod 502 is fixedly connected to a rotating rod 505. The arc-shaped splint 503 can be limited by the sliding rod 504, so that the arc-shaped splint 503 can only be raised and lowered but not rotated. The rotating rod 505 provides a reasonable force point for rotating the threaded rod 502, which is more convenient to use.

[0049] Working principle: When the cutting blade 603 needs to be replaced, the bolt 304 is first removed. At this time, the cutting blade 603 is only limited by multiple fixing rods 302. The cutting blade 603 can be removed by pulling the cutting blade 603 away from the fixing block 301. The disassembly is relatively simple. To replace the new cutting blade 603, you only need to align the reserved mounting hole on the cutting blade 603 with the fixing rod 302 and then insert it. Then, tighten the bolt 304 to complete the fixed installation of the cutting blade 603. This device reduces the installation parts of the cutting blade 603 and effectively improves the replacement speed of the cutting blade 603.

[0050] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
