[0018] The upper end of the hollow cylindrical tube 8 is threadedly connected with a cylindrical upper cover 9 for hanging the hanging ingot 10. The bottom end of the hollow cylindrical tube 8 is threadedly connected with a cylindrical base 2. In the middle section of the hollow cylindrical tube 8, there is a moving block 4 that can axially move along the inner cavity of the hollow cylindrical tube 8; a pin shaft 5 is installed around the circumference of the moving block 4. A circular hole 7 is opened on the side wall of the hollow cylindrical tube 8. One end of a support rod 6 is hinged to the pin shaft 5, and the other end of the support rod 6 passes through the circular hole 7 and obliquely downward to abut against the inner wall of the filament paper tube 11; a regulating rod 1 is fixedly connected to the moving block 4. The lower end of the regulating rod 1 passes through the center of the cylindrical base 2 and is threadedly connected with a locking nut 3, and the locking nut 3 is closely attached to the bottom end of the cylindrical base 2. By rotating the locking nut 3, the regulating rod 1 drives the moving block 4 to move downward, and then drives the tail end of the support rod 6 hinged to the moving block 4 to move upward. The tail end of the support rod 6 supports the filament paper tube 11 in contact with it so that it does not fall downward. A plurality of the support rods 6 are provided; the outer periphery of the hollow cylindrical tube 8 is sleeved with a filament paper tube 11. The hollow cylindrical tube 8 and the filament paper tube 11 are concentric. The filaments wound on the filament paper tube 11 are drawn out by the drafting roller 12.

[0019] Preferably, the number of the support rods 6 is at least three, so as to more stably support the filament paper tube 11, and four or five can also be selected according to different filament lengths and the weight of the filament paper tube 11. The support rods 6 are evenly distributed along the circumference of the moving block 4, and the lengths of the support rods 6 are the same, so that the forces on each support rod 6 are uniform.

[0020] Preferably, when the moving block 4 moves up and down, the support rod 6 rotates along the pin shaft 5. The diameter of the circular hole 7 on the side wall of the hollow cylindrical tube 8 is adapted to the rotation space of the support rod 6, so that the support rod 6 does not interfere with the circular hole 7 when rotating; the pin shaft 5 is in interference fit with the hole of the moving block 4.

[0021] Preferably, a friction pad 14 for preventing the filament paper tube 11 from sliding is installed at the tail end of the support rod 6, so as to better increase the friction force and holding force between the support rod 6 and the inner wall of the filament paper tube 11 and meet the load-bearing requirements of the filament paper tube 11.

[0022] Preferably, a through hole is opened in the center of the cylindrical upper cover 9. The bottom end of the through hole is a convex platform for hanging the lower support foot of the hanging ingot 10. A hook is provided at the bottom end of the cylindrical upper cover 9 for convenient suspension of the tension spring 13. The tension spring 13 installed at the bottom end of the cylindrical upper cover 9 is connected to the support rod 6. The cylindrical upper cover 9 has an external thread, and the upper end and the lower end of the hollow cylindrical tube 8 have internal threads. The cylindrical upper cover 9 is threadedly connected to the upper end of the hollow cylindrical tube 8. A groove for threadedly connecting the cylindrical upper cover 9 to the upper end of the hollow cylindrical tube 8 is provided on the upper end surface of the cylindrical upper cover 9; a groove for threadedly connecting the cylindrical base 2 to the lower end of the hollow cylindrical tube 8 is provided on the bottom end surface of the cylindrical base 2.

[0023] Preferably, the lengths of the tension springs 13 are the same, which are set according to the rotation angle of the support rod 6, and the number of the tension springs 13 is the same as that of the support rod 6, so that the support rod 6 is uniformly stressed.

[0024] Preferably, the moving block 4 is concentric with the hollow cylindrical tube 8, and the moving block 4 is made of high-density polyethylene (HDPE) material, which has good wear-resistant functional performance.

[0025] Preferably, the length of the support rod 6 is greater than the radius of the filament paper tube 11; the outer diameter of the hollow cylindrical tube 8 is smaller than the inner diameter of the filament paper tube 11 to meet the requirement of the hollow cylindrical tube 8 for hanging the filament paper tube 11.

[0026] During use, the combination of the moving block 4 and the adjusting rod 1 of the present invention is placed inside the hollow cylindrical tube 8, the support rod 6 is extended out of the circular hole 7 on the side wall of the hollow cylindrical tube 8, the cylindrical base 2 is passed through the adjusting rod 1 and screwed onto the bottom end of the hollow cylindrical tube 8, the locking nut 3 is screwed tightly on the adjusting rod 1 and closely abuts against the bottom end of the cylindrical base 2, one end of the tension spring 13 is connected to the support rod 6, the cylindrical upper cover 9 sleeves the support foot at the lower end of the bobbin 10, then the other end of the tension spring 13 is connected to the cylindrical upper cover 9, the cylindrical upper cover 9 is fixedly connected to the hollow cylindrical tube 8 by threading, and then the filament paper tube 11 is sleeved around the hollow cylindrical tube 8. Rotate the locking nut 3, the adjusting rod 1 drives the moving block 4 to move downward, and at the same time drives the tail end of the support rod 6 hinged to the moving block 4 to move upward, the support rod 6 extends outwards, the tail end of the support rod 6 abuts against the inner wall of the filament paper tube 11, so as to fixedly support the filament paper tube 11. The friction pad 14 at the tail end of the support rod 6 can increase the friction force on the filament paper tube 11, and the upward pulling force of the tension spring 13 installed on the cylindrical upper cover 9 strengthens the supporting force of the support rod 6 on the inner wall of the filament paper tube 11. The filaments on the filament paper tube 11 are drawn by the drafting roller 12 to produce unwinding and are put into production. When the production is completed and the filament paper tube 11 needs to be replaced, reverse-rotate the locking nut 3 on the adjusting rod 1 to make the support rod 6 on the moving block 4 contract downward, the support rod 6 disengages from the filament paper tube 11, and the old filament paper tube 11 can be removed or a new filament paper tube 11 can be replaced.
