[0031] The working principle or structural principle is as follows: When conveying raw materials for PP duct fittings, the distance between the first limiting roller 505 and the second limiting roller 602 can be adjusted according to the diameter of the raw materials. During adjustment, the operator can drive the lead screw 401 to rotate via a turntable. During the rotation of the lead screw 401, the threads on its surface will cause the slide plate 601 to shift and the first bevel gear 402 on the surface of the lead screw 401 to rotate. Because the first bevel gear 402 and the second bevel gear 501 mesh with each other, when the first bevel gear 402 rotates, it will cause the second bevel gear 501 and the bidirectional screw 502 to rotate, thereby driving the surface of the bidirectional screw 502... The slider 503 on the surface is displaced, thereby adjusting the distance between the first limiting roller 505 and the second limiting roller 602. Finally, the electric push rod 802 can be activated to adjust the distance between the third limiting roller 804. Finally, the reduction motor is activated to drive the rotating rod 704 to rotate. Because the rotating rod 704 is engaged with the worm gear 702, the rotation of the rotating rod 704 will cause the worm gear 702 to rotate. Utilizing the meshing relationship between the worm gear 702 and the worm wheel 701, the rotation of the worm gear 702 will drive the worm wheel 701 and the two second limiting rollers 602 to rotate in opposite directions, thereby completing the guiding and conveying operation of the clamped PP air duct material.

[0032] In summary, this device has the advantages of wide applicability and quick adjustment.
