[0021] In the utility model, the length of protective sleeve 3 is equal to the length of one half of yarn tube 4, and the end plate of one end of yarn tube 4 close to base 7 is fixedly connected with protective sleeve 3 by nesting mode.
[0022] In the utility model, the tension adjusting mechanism includes the limiting block 14 arranged on the outside of cover plate 1, the guide column 2 is symmetrically arranged at the other end of limiting block 14, the tension slide block 6 is sleeved on the outside of guide column 2, the top rod is further arranged at the center of one end of tension slide block 6 close to limiting block 14, the tension spring is further arranged in limiting block 14, and the top rod is connected to one end of tension spring. The top of limiting block 14 and cover plate 1 are fixedly connected by hinged mode.
[0023] In the utility model, the first wire passing hole 11 is arranged on one side of limiting block 14, the second wire passing hole 12 is further arranged on the outside surface of tension slide block 6, and the third wire passing hole 13 is arranged on the side of cover plate 1 close to limiting block 14.
[0024] In the utility model, the brake mechanism includes the draw hook 10 sleeved on the outside of one of guide columns 2, the brake block 5 is connected to the other end of draw hook 10, the brake pin 8 is arranged on the outside of base 7, the brake block 5 is rotatably connected to the center of brake pin 8, and the brake block 5 is connected to the recess arranged at the edge of one end of protective sleeve 3 close to base 7. The torsional spring is further arranged at the connecting place of brake block 5 and brake pin 8, and the both ends of brake pin 8 are fixedly connected by lock nut. The draw hook 10 is sleeved on one side of guide column 2 and arranged at the center position of guide column 2.
[0025] In use, first, the base 7 is installed on the rotary disc surface of the equipment, then the central rod 9, the bobbin 4, the protective sleeve 3 and the cover plate 1 are installed in sequence.
