[0038] like Figure 3 As shown, the outer wall of the support plate 13 is fixedly connected to a fixing seat 8, the outer wall of the fixing seat 8 is fixedly connected to a cylinder 9, the output end of the cylinder 9 is fixedly connected to a clamping plate 10, the end of the first rotating shaft 4 is fixedly connected to an adjusting wheel 7, and the clamping plate 10 is clamped and matched with the adjusting wheel 7.

A plurality of shaft frames 25 are fixedly connected to the inner wall of the support sleeve 24. The inner walls of the shaft frames 25 are rotatably connected to the second rotating shaft 26.

[0042] Working principle: The dual-axis motor 40 drives the worm 41 to rotate. The rotation of the worm 41 drives the rotation of the threaded rod 42 through the meshing of the worm wheel 43. As the threaded rod 42 rotates, the threaded block 44 moves spirally along its outer wall, and further drives the gear 46 to rotate through the connected toothed plate 45.

[0046] At the same time, the hydraulic rod 29 drives the support sleeve 24 to move along the outer wall of the feeding barrel 14 through the telescopic action of its piston rod, combined with the rotating head 30 and the hinge seat 31, so that the roller 27 in the feeding barrel 14 can roll along the slide groove 23 on the outer wall of the feeding barrel 14, so that the support sleeve 24 can adjust to the rotation angle of the feeding barrel 14 and effectively support the feeding barrel 14;
