When the first cutting blade 115 abuts against one side of the valve body 125, the first driving block 113a will stop driving the forward screw 109 to rotate until the second cutting blade 117 abuts against the other side of the valve body 125, and then the second driving assembly will flip over to leave a certain gap between the first cutting blade 115 and the second cutting blade 117, and then the hydraulic cylinder 103 will drive the lifting plate 104 to descend, pressing the waste material around the valve body 125, thereby cutting the waste material around the valve body 125.

[0039] The first driving assembly is used to drive the rotation of the first rotating shaft 106, and includes: a first motor 118, a first gear 119, and a second gear 120.

Then the hydraulic cylinder 103 drives the lifting plate 104 to descend, presses the waste materials around the valve body 125, and thus cuts the waste materials around the valve body 125. Then the hydraulic cylinder 103 drives the lifting plate 104 to rise, and then the first motor 118 drives the first gear 119 to rotate, and the rotation of the first gear 119 drives the second gear 120 to rotate, thereby driving the first rotating shaft 106 to rotate, and the rotation of the first rotating shaft 106 drives the first rotating plate 107 to rotate, thereby adjusting the positions of the first cutting blade 115 and the second cutting blade 117, thereby cutting the waste materials around the valve body 125.
