[0031] In this embodiment, the first double-head telescopic device includes a first hydraulic cylinder 1 and a second hydraulic cylinder 2, and the fixed end of the first hydraulic cylinder 1 and the fixed end of the second hydraulic cylinder 2 are fixedly connected, so that the piston rod of the first hydraulic cylinder 1 and the piston rod of the second hydraulic cylinder 2 are arranged oppositely.

[0032] Similarly, the second double-head telescopic device includes a third hydraulic cylinder 3 and a fourth hydraulic cylinder 4, and the fixed end of the third hydraulic cylinder 3 and the fixed end of the fourth hydraulic cylinder 4 are fixedly connected, so that the piston rod of the third hydraulic cylinder 3 and the piston rod of the fourth hydraulic cylinder 4 are arranged oppositely.

[0033] In addition, those skilled in the art may also replace the hydraulic cylinder with a gas cylinder or an electric telescopic rod or other equipment to achieve the telescopic effect.

[0034] In this embodiment, the first rotary drive device 7 is fixedly connected to the first saw disc 9 via a first connecting member, so as to achieve the technical effect that the rotation axis of the first rotary drive device 7 drives the first saw disc 9 to rotate.

[0035] Similarly, the second rotary drive device 8 is fixedly connected to the second saw disc 10 via a second connecting member, so as to achieve the technical effect that the rotation axis of the second rotary drive device 8 drives the second saw disc 10 to rotate.
