The debris is blocked to prevent the debris from splashing out of the connecting frame 2. When the telescopic end of the electric telescopic rod 3 continues to move downward, the plate body will not move downward, and the shell will move downward with it, so that the plate body slowly enters the shell, which will not affect the normal lifting and lowering of the telescopic end of the electric telescopic rod 3 and the cutting of the steel pipe by the cutting blade 41; when the electric telescopic rod 3 moves forward and backward, the connecting rod 37 moves forward and backward with it, and will not drive the shell to move; a vertical slide is provided on one side of the shell close to the connecting frame 2, and a slider slidably connected to the slide is fixed on the connecting frame 2, so that the shell can slide up and down; a slide rail located below the slide is also provided on one side of the shell close to the connecting frame 2, and a slide plate slidably connected to the slide rail is fixed on the end of the connecting rod 37, so that the connecting rod 37 can move forward and backward.

The fixed end of the No. 1 hydraulic rod 81 is fixed to the top of the base 1, and the telescopic end of the No. 1 hydraulic rod 81 is fixed to the vertical plate 8. According to the length of the steel pipe to be cut, the No. 1 hydraulic rod 81 can be started to make the vertical plate 8 close to or away from the connecting frame 2; when one end of the steel pipe passes through the inner side of the connecting frame 2, one end of the steel pipe is in contact with the vertical plate 8, which plays a role in positioning the steel pipe. At the same time, the two No. 2 hydraulic rods 82 can be started to make the two pressure blocks 83 contact the top and bottom surfaces of the steel pipe respectively (the two pressure blocks 83 are located between the two No. 2 hydraulic rods 82). After the two pressure blocks 83 clamp the steel pipe , which can increase the stability of the steel pipe. After multiple steel pipes are cut, the No. 1 hydraulic rod 81 can be started to move the vertical plate 8 away from the connecting frame 2, and the cut part of the steel pipe can be taken out of the connecting frame 2. Then the two No. 2 hydraulic rods 82 respectively drive the two pressing blocks 83 to move away from each other, and the cut part of the steel pipe falls downward, passes through the discharge port on the base 1, and falls into the external collection box (the external collection box is placed below the discharge port); then the vertical plate 8 is reset, and the staff pushes the steel pipe toward the vertical plate 8, so that the end of the steel pipe contacts the vertical plate 8, and the next cutting operation can be started.

The lower pressing plate 5 cooperates with the upper pressing plate 6 to fix the steel pipe; then the electric telescopic rod 3 is started to move the motor 4 downward, and the motor 4 is started to rotate the cutting blade 41. When the cutting blade 41 contacts the steel pipe, the steel pipe can be cut. When a steel pipe is cut, Afterwards, the electric telescopic rod 3 drives the motor 4 to move upward to restore, and then starts the conveying unit 31 to drive the electric telescopic rod 3 to move forward or backward.
