The upper roller 7 and the lower roller 8 are connected by parts 6, and an upper roller 7 is arranged between the two upper mounting seats 10, and a lower roller 8 is arranged between the two lower mounting seats 11. Shaft heads are arranged at both ends of the upper roller 7 and the lower roller 8. At the same time, plug-in sleeves 9 are horizontally rotatably installed inside the lower mounting seat 11 and the upper mounting seat 10, and the adjacent plug-in sleeves 9 and the shaft heads are connected by a self-disassembly structure; by rotating the hand wheel 5, the threaded rod 3 will drive the two bases 2 to move toward or in the opposite direction, so that the upper roller 7 and the lower roller 8 are installed between the two lower mounting seats 11 and the two upper mounting seats 10, and the support slide 19 and the lifting member 6 can adjust the height of the lower mounting seat 11, thereby changing the height of the lower roller 8.
[0019] The self-disassembly structure includes a card slot 13 opened on the outside of the shaft head, and a matching card plate 16 is horizontally arranged inside the plug-in sleeve 9 at the corresponding position of the card slot 13. The outer end of the card plate 16 and the two ends of the card slot 13 are arranged in a circular arc transition shape.
