The first clamping protrusion is located on one side of the circumference of the first protruding rib 5311 adjacent to the mounting hole 226. The second clamping portion 533 is provided with a receiving recess 5331, and is provided with a second convex rib 5332 and a second clamping protrusion 5333. The second convex rib 5332 is located at one side of the circumference of the receiving recess 5331 adjacent to the mounting hole 226. The size of the second convex rib 5332 along the circumference of the mounting hole 226 is larger than the size of the second clamping protrusion 5333 along the circumference of the mounting hole 226. The second clamping protrusion 5333 is located at one side of the circumference of the second clamping rib adjacent to the mounting hole 226. The first clamping portion 531 of each arc plate 53 is clamped with the second clamping portion 533 of the arc plate 53 on the adjacent side.

By pulling out the multiple arc plates 53 in the longitudinal direction, the disassembly of the loose tube assembly 50 can be achieved. For example, in order to facilitate the engagement of the arc plate 53 with the drive shaft, the inner side of each arc plate 53 is convexly provided with an engagement rib plate, and the peripheral surface of the drive shaft is concavely provided with a plurality of grooves, and the engagement rib plates of the multiple arc plates 53 are respectively inserted into the multiple grooves of the drive column, thereby achieving the engagement of the drive shaft with the multiple arc plates 53, so that the power member can drive the multiple arc plates 53 by the drive shaft to drive the multiple connecting rods 52 to rotate. For example, the driving shaft includes a mounting end and a sealing end that are arranged opposite to each other. The mounting end is detachably connected to the first transmission shaft 421 , and the sealing end is located in the circular hole 225 of the support plate 22 .

The piston groove 229 is hidden in the support plate 22. The length of the piston groove 229 is greater than the length of the longitudinal groove 2257. A one-way valve is provided at the bottom of the piston groove 229. The frame 20 further includes a flip cover assembly 27. The flip cover assembly 27 includes a flip cover 271, a support rod 272 and a piston rod 273. The flip cover 271 is rotatably mounted on the support plate 22 and is used to align and close the through circular hole 225 to close the through circular hole 225. The flip cover 271 includes a shielding circular plate 2711, the diameter of which is larger than the diameter of the through hole 225, and the shielding circular plate 2711 is used to shield one side of the through hole 225. The shielding circular plate 2711 is provided with a sealing circular plate 2715 protruding from the side of the through hole 225, and the sealing circular plate 2715 is inserted into the through hole 225, and the circumference of the sealing circular plate 2715 and the inner circumference of the through hole 225 are mutually fitted to achieve sealing of the through hole 225. The circumference of the sealing circular plate 2715 is provided with a through hole 2716, and the through hole 2716 passes through the center of the sealing circular plate 2715. A connecting hole is provided through the side wall of the support plate 22, and the connecting hole is coaxially arranged with the through hole 2716 and is mutually connected. An arc-shaped supporting groove 2255 is concavely formed on the surface of the sealing circular plate 2715 facing the through circular hole 225 . The arc-shaped supporting groove 2255 penetrates the circumferential surface of the sealing circular plate 2715 and is vertically connected to the middle of the through hole 2716 .

[0033] For example, the diameter of the support rod 272 is equal to the width of the slot 228, one end of the support rod 272 is rotatably connected to the center of the surface of the shielding circular plate 2711 of the flip circular cover 271, and the other end of the support rod 272 is provided with a pivot ball 2725, the diameter of the pivot ball 2725 is greater than the diameter of the support rod 272 and is equal to the diameter of the cross section of the longitudinal groove 2257, the pivot ball 2725 is movably arranged in the longitudinal groove 2257, the piston rod 273 is slidably arranged in the piston groove 229, the circumference of the piston rod 273 is closely fitted with the circumference of the piston groove 229, so that a piston cavity is formed at the bottom of the piston groove 229. The top end of the piston rod 273 is rotatably connected to the pivot ball 2725, and the length of the support rod 272 is greater than the diameter of the shielding circular plate 2711. When the through circular hole 225 is opened, the shielding circular plate 2711 is used to flip outward relative to the support plate 22 to a position perpendicular to the support plate 22, and the support rod 272 is used to rotate relative to the piston rod 273 under the drive of the shielding circular plate 2711, and drive the pivot ball 2725 to move downward, so that the piston rod 273 moves downward to compress the air in the piston chamber. The piston chamber is used to support the piston rod 273 through compressed air to position the flip circular cover 271. At this time, the one-way valve is closed. When the drive shaft needs to be installed, the drive shaft is used to be supported on the arc-shaped support groove 2255 on the sealing circular plate 2715 and inserted into the through circular hole 225. After the drive shaft is installed, the flip cover 271 is flipped with force. The flip cover 271 is used to drive the support rod 272 to rotate, and the support rod 272 is used to pull the piston rod 273 up. The one-way valve is used to connect the piston groove 229 with the outside world so that the piston rod 273 can rise smoothly. The flip cover assembly 27 is convenient for closing or disassembling the perforated circular hole 225. The flip cover assembly 27 is also convenient for supporting the flip cover 271 at a position perpendicular to the support plate 22. Since the shielding cover is against the periphery of the perforated circular hole 225, the support plate 22 can be tilted relative to the bottom surface instead of being perpendicular to the ground. Therefore, when the shielding circular plate 2711 is flipped open, the tilt angle of the support rod 272 facilitates the shielding circular plate 2711 to drive the support rod 272 to flip outward smoothly and descend along the longitudinal groove 2257.

[0034] For example, in order to facilitate supporting the two discs 51, the frame 20 further includes a support frame 28 and a rigid frame 29, wherein the support frame 28 is mounted on the base plate 21, and the support frame 28 includes a support tube 281, a compression spring and a support bent plate 282, wherein the bottom of the support tube 281 extends toward the base plate 21, one end of the compression spring is inserted into the inner side of the bottom of the support tube 281, and the other end is connected to the base plate 21 to support the support tube 281, and the middle of the support bent plate 282 is vertically connected to the top of the support tube 281, and the opposite ends of the support bent plate 282 are respectively provided with arc-shaped matching plates 2825, and the two arc-shaped matching plates 2825 are respectively adjacent to the two support plates 22 and are respectively located below the two discs 51 to support the two discs 51. By providing the support frame 28, it is convenient to support the loose tube assembly 50. For example, in one embodiment, the rigid frame 29 and the line supply assembly 30 are staggered to facilitate the installation of the rigid frame 29, for example, the rigid frame 29 is located at the unextended part of the guide rod 34. For example, in order to facilitate the support bent plate 282 to be pushed open during use, the rigid frame 29 includes a rigid rod 291, a penetration tube 292, a shell 293 and a support frame 295. The rigid rod 291 is convexly disposed on the support plate 22 and is provided with a clamping groove 2911. The clamping groove 2911 is a rectangular groove and extends along the length direction of the rigid rod 291. The penetration tube 292 is slidably penetrated in the connecting hole of the support plate 22 and the through hole 2716 of the sealing circular plate 2715. An oil delivery hole is formed in the penetration tube 292. A plurality of oil overflow holes are arranged in the middle of the penetration tube 292. The plurality of oil overflow holes are all connected with the oil delivery hole and exposed in the arc-shaped support groove 2255. The plurality of oil overflow holes face the plurality of arc-shaped plates 53. The plurality of oil overflow holes are located at the end of the oil delivery hole. The housing 293 is fixed to the end of the penetration tube 292 away from the oil overflow hole and is slidably arranged on the surface of the rigid rod 291. The abutting frame 295 includes a rectangular bar 2951 and an abutting bar 2955. The rectangular bar 2951 is transversely penetrated in the clamping groove 2911. One end of the rectangular bar 2951 is fixed to the housing 293. The rectangular bar 2951 is tilted relative to the bottom plate 21. The distance between the rectangular bar 2951 and the bottom plate 21 gradually decreases in the direction toward the driving assembly. The abutting bar 2955 is connected to the end of the rectangular bar 2951 away from the housing 293. One end of the abutting bar 2955 extends obliquely toward the supporting bent plate 282. The distance between the abutting bar 2955 and the penetration tube 292 gradually decreases in the direction toward the disc 51. The distance between the abutting bar 2955 and the bottom plate 21 gradually decreases in the direction toward the housing 293.The end of the abutting strip 2955 is slidably abutted against the end of one of the disks 51 to position the disk 51, so that the axis of the disk 51 has a small jump during the rotation process. The end of the abutting strip 2955 is located above the supporting bent plate 282. An oil bag is provided in the housing 293, and the top of the oil bag is protruding from the top of the housing 293.

[0035] When the rigid frame 29 is inserted, the shell 293 is subjected to force to push the penetration tube 292 into the connecting hole and the through hole 2716, so as to fix the sealing circular plate 2715 in the penetration circular hole 225 and expose the multiple oil overflow holes in the arc-shaped support groove 2255. The bottom of the shell 293 and the rectangular bar 2951 slide toward the support plate 22 along the rigid rod 291, and the end of the abutting bar 2955 is used to slide from one side of the disc 51 to the other side and remain abutted on the disc 51. The end of the abutting bar 2955 adjacent to the shell 293 is used to move toward the support bent plate 282 to abut the support bent plate 282, so that the support tube 281 drives the support bent plate 282 to move downward, forcing the two arc-shaped matching plates 2825 to descend to separate from the circumferential surface of the two discs 51. After that, the power member can drive the loose tube assembly 50 to rotate freely to wind the polyester embroidery thread. The cooperation between the rectangular strip 2951 and the rigid rod 291 can prevent the support frame 295 from deflecting, thereby achieving the function of positioning the circular plate and supporting the support curved plate 282 downward. After the top of the oil bag is stressed, it is used to allow the lubricating oil to reach the multiple oil overflow holes through the oil delivery hole, and then flow into the perforated circular hole 225 to lubricate the loose tube assembly 50, and also lubricate the circumference of the sealing circular plate 2715, and improve the circumferential sealing performance of the sealing circular plate 2715. When disassembling the loose tube assembly 50, the support frame 295 is pulled outwards to make the support rod detach from the support bent plate 282. The support bent plate 282 drives the two arc-shaped matching plates 2825 to rise under the action of the compression spring to support the two discs 51, and the piercing tube 292 moves outwards to detach from the flip round cover 271, so that the flip round cover 271 can be flipped out and perpendicular to the support plate 22. Since there is no piercing tube 292 in the arc-shaped support groove 2255 on the flip round cover 271, the drive shaft just pulled out can be supported more conveniently. The surface of the sealing circular plate 2715 is used to align with the top surface of the arc-shaped plate 53 at the bottom, so that the drive shaft can smoothly slide onto the arc-shaped support groove 2255. On one hand, the rigid frame 29 can support the support bent plate 282 to separate from the two discs 51, and on the other hand, can position the disc 51, and conveniently fix the sealing disc 2715 and inject lubricating oil, thereby achieving multiple effects at one stroke.
