Since the distance from the measuring block 311 to the measuring rod 312 is fixed, the position of the point to be cut on the tube body can be quickly read through the scale groove 313.

[0035] Next, manually slide the distance measuring block 314 along the outer wall of the scale groove 313, use a marker pen 10 to mark the stop position of the distance measuring block 314 along the edge line of the distance measuring block 314, turn on the first motor 203 to rotate the screw rod 204, and the wire sleeve 205 will move along the outer wall of the screw rod 204, thereby moving the clamping and measuring component 3. When the clamping and measuring component 3 moves, the squeezing of the tube body by the clamping and rotating component 8 is released, so that only the clamping and measuring component 3 can clamp the tube body, so that the position to be cut is moved to the cutting component 7, and the second electric cylinder 5 is turned on to move the limit block 602 back and forth. First, the cutting component 7 is adjusted to move back and forth to the position where cutting is required, and then the linear module 603 is turned on to move the cutting component 7, and the second motor 703 is turned on to rotate the cutting disk 702 to cut the clamped and fixed tube body. The second fixing ring 809 is manually rotated to achieve rotational cutting of the tube body. After the cutting is completed, the squeezing of the tube body is released to facilitate the rapid unloading of the tube body.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
