[0040] The working principle of the above embodiment is:

[0041] (1) When the universal joint is used for controlled cutting, the movable sleeve 22 can slide along the slide bar 21.

This design allows the cutting speed to be accurately adjusted according to different cutting requirements.

[0042] (2) When the universal joint is used for distance clamping, the guide wheel 31 guides the object to be cut to ensure its stability during the cutting process. The two cylinders 34 are fixed on the inner wall of the connecting box 33 respectively. The clamping block 35 is fixed on the output shaft of the cylinder 34. By controlling the extension and contraction of the cylinder 34, the clamping force of the clamping block 35 on the object to be cut can be adjusted to ensure that the object does not move during the cutting process. The distance piece 36 is used to adjust the cutting length. By rotating the hand wheel, the position of the distance screw 362 can be adjusted, thereby changing the distance between the distance plate 363 and the clamping seat 32 to achieve precise cutting length control. The distance plate 363 is slidably connected to the slide rail through a slide groove. In this way, the position of the distance plate 363 can be adjusted as needed before cutting to meet the requirements of cutting of different lengths.
