Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 10, the three-piece inclined middle bundle core comprises a spiral 1, beads 2 and a middle bundle 3, wherein the beads 2 extend into the spiral 1 and are engaged with the spiral 1, the middle bundle 3 is coated outside the spiral 1 and the beads 2, the middle bundle 3 is connected with the spiral 1 in a circumferential rotating manner, the upper part of the beads 2 is clamped with the middle bundle 3 in the circumferential direction, and the beads 2 can be driven by the middle bundle 3 to rotate and lift. Spiral 1, pearl 2 adopt POM to make, well bundle 3 adopts ABS to make, the utility model discloses well bundle core is made by three subassembly, sets up through the cooperation of three subassemblies, has saved the fork in traditional well bundle core, rocks when each subassembly of bundle core cooperates in the reducible, and the subassembly cooperation is firm more reliable.

The bead 2 comprises a stud 21, the outer wall of the stud 21 is provided with an external thread 211, and the annular inner wall of the spiral 1 is provided with an internal thread 11 meshed with the external thread 211.

The internal thread 11 includes a pair of internal threads 11 arranged in central symmetry. The lower end of the stud 21 is provided with a pair of open grooves 24, and the upper end of the spiral 1 is provided with a pair of longitudinal through grooves 16, so that the beads 2 and the spiral 1 can be conveniently installed. Still be equipped with the stopper 25 of a pair of symmetry on the double-screw bolt 21, stopper 25 connects bottom twice external screw thread 211, and when pearl 2 removed to stopper 25 correspond with internal thread 11 butt, pearl 2 no longer shifts up, and stopper 25's setting is used for preventing that pearl 2 from unscrewing spiral 1.
