Since the cross-section of the lower guide ring 40 is circular, the friction is small when the silk thread is transported along the lower guide ring 40, and the lower guide ring 40 is movably connected in the placement annular groove. Therefore, when the tension is large, the lower guide ring 40 is not easy to tighten and clamp the silk thread or even break it.

[0023] Furthermore, a central connecting column 22 extending upward is formed in the middle of the top surface of the twisting disk 20, and a connecting seat 30 is movably connected to the central connecting column 22 through a bearing.

[0025] An upwardly extending mounting sleeve 34 is formed in the middle of the bottom plate on which the connecting seat 30 is placed, and the bottom end of the middle through hole of the mounting sleeve 34 extends out of the bottom surface of the bottom plate on which the connecting seat 30 is placed. The central connecting column 22 is inserted into the bottom end of the middle through hole of the mounting sleeve 34 and is movably connected to the mounting sleeve 34 through a bearing.

[0026] The installation sleeve 34 is provided with a yarn cylinder 100, the top surface of the yarn cylinder 100 is pressed against a guide connection seat 50, a guide cylinder 51 is fixed to the bottom surface of the bottom plate of the guide connection seat 50, the guide cylinder 51 is inserted into the yarn cylinder 100, and the outer wall of the guide cylinder 51 is close to or in close contact with the inner wall of the yarn cylinder 100.

[0027] Furthermore, a feed pipe 52 is movably connected to the top surface of the bottom plate of the guide connecting seat 50 through a bearing, and the central through hole of the feed pipe 52 is communicated with the central through hole of the bottom plate of the guide connecting seat 50, and the central through hole of the bottom plate of the guide connecting seat 50 is communicated with the central through hole of an intermediate guide tube 53 fixed in the middle part of the bottom surface of the bottom plate of the guide connecting seat 50, and the bottom end of the central through hole of the intermediate guide tube 53 faces the central through hole of the extension tube 222 fixed on the top of the central connecting column 22, and the central through hole of the extension tube 222 is communicated with the central hole 221 of the central connecting column 22.

[0029] The upper guide ring body 55 is a ring body with a circular cross section.

[0030] When this embodiment is in use, the polyester low-elastic yarn wound on its yarn tube 100 passes through the annular groove between the upper guide ring body 55 and the outer annular groove 54, and then enters the feed tube 52 along the ceramic feed port at the top of the feed tube 52, and then passes through the middle guide tube 53, the extension tube 222, and the center hole 221 of the center connecting column 22, and finally, is led out from the side lead-out hole 23, and then, is guided by the lower guide ring 40, and upward passes through the center through hole of the hub 80 above the guide connecting seat 50, wherein the transmission wheel of the connecting shaft 21 is driven to rotate by the driving belt of the main driving motor installed on the frame 10, so that the twisting disk 20 rotates, so that the polyester low-elastic yarn is twisted during the transportation process.
