[0020] A cutting machine for cutting round tubes is installed on the processing table 1 .

[0021] Specifically, a first linear motor 8 for driving the sliding plate 4 to move is installed on the top of the processing table 1 .

[0022] In this embodiment, when the driving mechanism does not drive the clamping rod 16 to cooperate with the fixing rod 3 to clamp the round tube sleeved on the fixing rod 3, the first linear motor 8 can drive the sliding plate 4 to move so as to push the round tube to move.

[0023] Specifically, a second linear motor 9 is installed on the top of the processing table 1, and a slide of the second linear motor 9 is connected to a movable plate 10. The top of the movable plate 10 is liftably connected to a support block 12 that cooperates with the fixed rod 3 to support the round tube.

[0024] An electric push rod 11 is installed on the top of the movable plate 10 , and the output shaft of the electric push rod 11 is connected to the supporting block 12 .

[0025] In this embodiment, when the round tube is cut, the part of the round tube that is not mounted on the fixed rod 3 can be supported by the support block 12. The second linear motor 9, the movable plate 10 and the electric push rod 11 are arranged to facilitate the adjustment of the position and height of the support block 12.

[0026] Specifically, a V-shaped groove 13 is formed on the top of the support block 12 .
