[0025] Working principle:

[0026] When in use, first adjust the two rotating adjustment hand wheels 29 on one side of the machine body 1. The rotation of the adjusting hand wheels 29 drives the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, it drives the moving seat 24 threadedly connected thereto to move along the guide rail 22. In the process of movement, the positional relationship of the two clamping frames 21 is adjusted, that is, the direction in which the tubular workpiece is fixed is adjusted. After the adjustment is completed, the tubular workpiece can be placed against the clamping frame 21, and the placement direction of the tubular workpiece can be controlled, which plays a guiding role. When the placement direction of the tubular workpiece is After confirmation, the two adjusting hand wheels 29 on the other side of the machine body 1 are turned to move the movable seat 24 and drive the two clamping frames 21 connected thereto to continuously approach the tubular workpiece. When the two clamping frames 21 on the other side come into contact with the tubular workpiece, since the clamping frames 21 are rotatably connected to the connecting rod 23, when the adjusting hand wheel 29 is continuously turned, the clamping frames 21 will rotate with the shape of the tubular workpiece to better fit the workpiece. As the adjusting hand wheel 29 continues to rotate, the tubular workpiece will be clamped by the clamping frames 21 to complete the guiding and clamping of the workpiece.

[0027] When it is necessary to cut a tubular workpiece, first adjust the height and position of the cutting mechanism 3 according to the shape and size of the tubular workpiece, unscrew the limit bolt 32 outward, and then adjust the height of the cutting cross bar 33 up and down along the upright seat 31, so that the height of the cutting blade 310 is higher than the tubular workpiece, and then screw in the limit bolt 32 until its top reaches the through hole on the side wall of the upright seat 31, and then unscrew the adjusting bolt 38, and move the position of the adjusting moving frame 35 along the cutting cross bar 33 until the cutting blade 310 reaches directly above the tubular workpiece, and then screw in the adjusting bolt 38 until the top of the adjusting bolt 38 is pressed against the outer wall of the cutting cross bar 33, and the fixing of the moving frame 35 is completed by the action of friction.

[0028] When the position adjustment of the cutting mechanism 3 is completed, the cutting machine shaft 311 is driven to rotate by the external motor, and the rotation of the cutting machine shaft 311 drives the cutting blade 310 to rotate. At this time, the protective push handle 37 is pulled upward, and the L-shaped rod 36 connected thereto will rotate along the return shaft 342. The L-shaped rod 36 will drive the cutting blade 310 connected thereto to move downward to complete the cutting of the tubular workpiece. When the L-shaped rod 36 drives the return shaft 342 to rotate, the baffle 345 fixedly connected to the return shaft 342 also rotates accordingly. The connected connecting spring 343 rotates and compresses to generate a rebound force. When the cutting is completed, the pull on the protective push handle 37 is released. Then, under the action of the rebound force generated when the connecting spring 343 is compressed, the return shaft 342 will rotate in the opposite direction, and drive the L-shaped rod 36 connected to it to rotate. The L-shaped rod 36 will drive the cutting blade 310 to reset until the stop pin 344 reaches the farthest point of the through slot. At this time, the stop pin 344 is limited by the through slot to complete the reset task. In addition, a circular protective plate is provided on the protective push handle 37 to ensure the safety during the operation of the cutting machine.
