The flat cable host 16 of the present invention is a prior art and will not be described herein.
The working principle of the invention is as follows:
when the input shaft 10 rotates counterclockwise, the balance frame a11, the fixed rod 14, and the balance frame B12, which are integrally formed, incline with the rotation of the input shaft 10, facing the input shaft 10; the wire host 16 is also tilted due to the action of the fixed lever 14 (in contact with the upper and lower rollers 18, 19). During tilting, the antenna 17 on the balancing stand B12 gradually approaches the plane of the lateral edge of the side L-shaped bracket 4. At the same time, fork 5 is inclined in a direction approaching screw A2 at fork angle a501 and fork angle B502, and is inclined in an opposite direction (tilted upward) at fork angle C503 and fork angle D504 on the other side. When the antenna 17 contacts with the plane of the support 4, the flat cable host 16, the balance frame A11, the balance frame B12 and the fixed rod 14 connected with the flat cable host are not inclined any more; at this time, the winding displacement main body 16 is continuously moved leftward due to the rotation of the input shaft 10, and as the fork 5 is continuously moved closer to the stopper A3, the fork angle a501 of the fork 5 is brought into contact with the stopper A3 due to the inclination of the fork 5, and the fork angle D504 is not brought into contact with the stopper A3 due to the reverse upward tilting of the fork angle D504 with respect to the fork angle a501 (as in the conventional polish rod winding displacement device). The stop block A3 pushes the shifting fork 5 to the other side (the torsion spring 6 assists the shifting fork 5 to rotate), so that reversing is realized. When the shift fork is moved to the other end, the fork angle B502 of the fork 5 contacts the stopper B13, and the fork 5 is pushed back again by operating the stopper B13 as described above.
When the input shaft 10 rotates clockwise, the fork angle C503 and the fork angle D504 of the fork 5 incline towards the direction close to the lead screw B7, and the reciprocating motion of the wire arranging main machine 16 can be realized, so that the reciprocating motion of the wire arranging main machine 16 can be realized no matter how the input shaft 10 rotates, and the optical fibers are uniformly wound and unwound through the guide wheels 16.
