[0030] In this embodiment, a strip base 1 is included, and a rotating structure is provided on the lower wall of the strip base 1. A tension fixing structure is provided on the rotating structure.

[0031] The rotating structure includes: an annular slide rail 2, rollers 3, and an annular frame 4;

[0032] A first annular groove is formed on the upper wall of the strip base 1. An annular slide rail 2 is placed inside the first annular groove. Multiple first rollers 3 are installed on the annular slide rail 2. A first annular groove is formed on the inner wall of the first annular groove. A slide frame 5 is inserted into the first annular groove. A first connecting rod 6 is installed between the slide frame 5 and the first roller 3. An annular frame 4 is placed on the upper wall of the first roller 3. A first support 7 is placed on the upper wall of the annular frame 4. A disc 8 is fixed on the upper wall of the first support 7. A tensioning structure is placed on the disc 8. Multiple first circular slots are formed on the upper wall of the disc 8. A first circular groove with a corresponding position is inserted into each first circular slot. A first bearing 9 is inserted into the first circular groove. A crossbar is installed on the first bearing 9. A first pulley 20 is fitted on the crossbar.

[0033] It should be noted that:

[0034] The first roller 3 on the annular slide rail 2 in the first annular groove on the strip base 1 can move. Because of the annular slide rail 2, the first roller 3 moves in a circular motion, which makes the disc 8 rotate and adjust the angle of use. The first bearing 9 inserted in the first circular slot on the disc 8 can rotate itself, thereby driving the first roller 3 to rotate. When the item is placed on the disc 8, the disc 8 rotates to adjust the position of use, which makes it easier to adjust the placement of the item. When the item is pulled, the first roller 3 contacts the lower wall of the item and rotates due to the friction generated by the item being pulled, which reduces friction and makes it easier to drag the item.

[0035] The tensioning structure includes: a first guide rod 10, a sleeve 11, a support frame 12, a second bearing 13, and a second pulley 14;

[0036] A pair of second brackets 15 are fixed on the side wall of the disc 8. A first guide rod 10 is placed on each second bracket 15. A sleeve 11 is fitted onto the first guide rod 10. A support column 16 is fixed on the lower wall of the bearing frame 12. A second pulley 14 is placed on the lower wall of the support column 16. A support plate 17 is fixed on the bearing frame 12. A first slot is opened on the support plate 17. A rod 18 is inserted into the first slot. A top plate 19 is installed on the rod 18. A second circular groove is opened on both sides of the top plate 19. A second bearing 13 is inserted into the second circular groove. A third support column 21 is inserted into the second bearing 13. A clamping plate 22 is fixed on the third support column 21.

[0037] It should be noted that: the second bracket 15 on the disc 8 serves as a support to support the sleeve 11 on the first guide rod 10. The sleeve 11 can be pulled to adjust the overall length of the first guide rod 10 and the sleeve 11. Pulling the sleeve 11 adjusts the position of the support frame 12. The support frame 12 supports the lower end of the item. When the item is large, pulling the sleeve 11 makes it easier for the support frame 12 to support the lower sides of the item, making it easier to place the item. The first slot on the support plate 17 allows the insertion of the rod 18 on the top plate 19. Pulling the top plate 19 adjusts the support height, making it easier to clamp the sides of the item. Then, the clamping plate 22 on the third pillar 21 on the third bearing 34 swings to clamp the front and rear sides of the item.

[0038] As a preferred technical solution, further, a strip frame 23 is fixed on the disc 8 between a pair of second supports 15.

The inclined strip plate 24 has a strip-shaped through hole, and the inner wall of the strip-shaped through hole has a corresponding third circular groove. A third bearing 34 is inserted into each third circular groove, and a roller 25 is inserted between the third bearings 34. The inclined strip plate 24 facilitates the pushing of items onto the disc 8 or pulling them down by the disc 8. The roller 25 inserted in the third bearing 34 can rotate, reducing friction and facilitating the pushing of items. Furthermore, the inclined strip plate 24 is inserted into the first mounting groove by the locking piece, so it can be disassembled, making it convenient to place items in other parts of the platform.

[0039] As a preferred technical solution, both the clamping plate 22 and the top plate 19 are provided with a second mounting groove, and the clamping plate 22 and the top plate 19 are connected by a reinforcing rib 26 with a clip that can be inserted into the second mounting groove; the reinforcing rib 26 facilitates the fixing and support of the clamping plate 22, and can be disassembled for flexible use.

[0040] As a preferred technical solution, a ring frame 27 is fixed on the strip base 1, and a second ring groove is provided on the ring frame 27. A slide body 35 inserted into the second ring groove is installed on the ring frame 4; the slide 5 plays a traction and limiting role.

[0041] As a preferred technical solution, the sleeve 11 is further provided with a first threaded opening, and the first guide rod 10 is provided with a first threaded groove that matches the first threaded opening. A first screw 28 that engages with the first threaded groove is inserted into the first threaded opening. When the first screw 28 is turned, the sleeve 11 is fixed, thereby fixing the support frame 12 for use.

[0042] As a preferred technical solution, a second threaded opening is provided on the strip base 1 near each of the four corners, and a second screw 29 is inserted into the second threaded opening; the second screw 29 is turned to fix the device.
