When the rigid frame 29 is inserted, the housing 293 is forced to push the penetrating cylinder 292 into the communication hole and the through hole 2716, so as to fix the sealing circular plate 2715 in the penetrating circular hole 225, and expose the oil spilling holes in the arc-shaped supporting groove 2255, the bottom of the housing 293 and the rectangular bar 2951 slide along the rigid rod 291 toward the supporting plate 22, the end of the abutting bar 2955 slides from one side of the circular plate 51 to the other side, and is kept abutting against the circular plate 51, the end of the abutting bar 2955 adjacent to the housing 293 is used to move toward the supporting bent plate 282 to abut against the supporting bent plate 282, so that the supporting cylinder 281 drives the supporting bent plate 282 to move downward, and the two arc-shaped engaging plates 2825 are forced to move downward to separate from the peripheral surfaces of the two circular plates 51. Thereafter, the power member can drive the loose bobbin assembly 50 to rotate freely to wind the polyester embroidery thread. The cooperation between the rectangular bar 2951 and the rigid rod 291 prevents the support frame 295 from deflecting, thereby positioning the circular plate and supporting the curved support plate 282 downward. After being stressed, the top of the oil bag is used for enabling lubricating oil to reach the plurality of oil overflow holes through the oil conveying holes and further flow into the penetrating round hole 225 to lubricate the tube loosening assembly 50, lubricate the circumferential surface of the sealing circular plate 2715 and improve the sealing performance of the circumferential surface of the sealing circular plate 2715. When the loosening barrel assembly 50 is disassembled, the abutting frame body 295 is pulled outwards, so that the abutting rod is separated from the supporting bent plate 282, the supporting bent plate 282 drives the two arc-shaped engaging plates 2825 to ascend under the action of the pressure spring to support the two discs 51, the penetrating barrel 292 moves outwards to be separated from the overturning round cover 271, so that the overturning round cover 271 can be overturned out and is perpendicular to the supporting plate 22, and the driving shaft which is just pulled out can be conveniently supported because the penetrating barrel 292 is not arranged in the arc-shaped supporting groove 2255 on the overturning round cover 271. The surface of the seal circular plate 2715 is adapted to be aligned with the top surface of the arc plate 53 positioned lowermost therein so that the drive shaft can smoothly slide onto the arc support groove 2255. The rigid frame 29 can support the supporting bent plate 282 to separate from the two circular discs 51, and can position the circular discs 51, facilitate fixing the sealing circular plate 2715, and facilitate injecting lubricating oil, thereby achieving multiple purposes.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
