Description of the Invention: [Technical Field] The present invention relates to a special connector for a fiber optic connector, and more particularly to a structural design of a cleaning tape drive device in the cleaner. [Previous technology] When the fiber connector is connected to the fiber through the fiber optic cable, when the signal is connected, in order to ensure the quality of the connection and transmission, the staff will use the fiber connector to construct the wiring. A special cleaner for the fiber optic connector, which is surface-cleaned to remove dirt on the surface. At present, the existing components of the special connector for the optical fiber connector mainly include a hollow casing, a reeling wheel set and a driving device. The material casing is opposite to each other by the two casings, and the winding reel set includes a cleaning belt. The wheel and a reel are respectively pivoted inside the casing, and the cleaning pulley is wound around a cleaning belt, and the cleaning belt is connected at one end to the winding reel and through a preset cleaning window on the casing, the driving device The utility model comprises a dialing member disposed on the outer casing, and a connecting rod driving assembly being arranged in the outer casing and connected between the sliding member and the winding reel, the one end of the retracting wheel being provided with a one-way ratchet portion, the connecting rod driving One of the transmission members of the group is provided with a one-way pusher block, and correspondingly cooperates with the one-way ratchet portion. In the month of use, the cleansing person uses the toggle member to push the reeling wheel to rotate through the connecting rod drive group, and then pulls a small clean cleaning belt from the cleaning pulley to dispose of the cleaning window of the outer casing. The user can rub the fiber connector on the small cleaning tape to remove the dirt of the fiber to achieve the purpose of cleaning. However, the foregoing cleaner provides a cleaning device for the optical fiber connector. However, in the case of the cleaning device, the cleaning device uses the dial member to push the reeling wheel to rotate by a certain angle through the connecting rod driving group, wherein the rewinding wheel is used. In the initial stage, only a small length of cleaning tape is wound, the overall diameter is small, and the outer circumference is also short. Therefore, when the winding wheel is turned to the angle, the length of the cleaning belt is about a small length corresponding to the outer piece and/or the month. The length of the noodle mouth's, but as the reeling wheel continues to retract the used cleaning tape, it will increase its diameter and increase the relative outer circumference. Therefore, when the reeling wheel rotates m, it will self-clean the belt. The roll-out is greater than the length of the initial roll-out, so that the cleaning is not fully utilized with some of the sections, and the used sections are taken up to the take-up reel, causing unnecessary waste. SUMMARY OF THE INVENTION The main object of the present invention is to provide a fixed-length transmission device for a fiber-optic joint, which is designed to solve the problem of waste of the cleaning belt when the cleaner is used. In order to achieve the foregoing object, the fixed length transmission device proposed by the present invention is disposed in a casing of a cleaning crucible, and the fixed length transmission includes an I pressing member, a rotating member, a driving member and a a pressing plate, wherein: the:Heiling pressing member is disposed at a notch of the outer casing with a torque end thereof, and a connecting rod having a protruding block is pivoted at the other end; the rotating member is pivotally disposed on the winding wheel of the winding reel a side end, and abutting the tab with 1 to cooperate with the one-way ratchet portion of the retracting wheel side end, the rotating side is additionally provided with a gear portion; and the driving member is connected by the tooth of the side thereof, The driving member is further provided with a strip portion on the side of the driving member, and a gear hole portion of the rotating member is provided for the connecting rod protrusion to be disposed on the protruding post, and the torsion spring is abutted thereon 1288255 - Between the driving member and the bump; One end of the pressing plate is coupled with the torsion spring and is disposed on the wheel seat of the winding wheel set. The two ends of the torsion spring respectively abut the pressing plate and the wheel seat, and one side of the pressing plate has an arc convex portion corresponding to the protruding column. The invention is designed by the prior art, and is characterized in that: the main advantage is that the pressing member in the fixed length transmission device abuts the torsion spring via the connecting rod bump, and indirectly drives the driving member with the rack portion and the rotating member gear The meshing transmission is used to drive the winding reel to rotate the cleaning belt, and the pressing plate on the cleaning roller of the reeling reel is used to limit the structural design of the driving stroke of the driving member, so that the stroke of each pressing member is pressed. In the middle, the rotation angle of the rotating reeling wheel can be automatically adjusted according to the winding reel of the reeling wheel, and then the reeling wheel can be controlled to rotate a certain length of the cleaning belt to the cleaning window, so that each wiping is used. The cleaning belts are all unused sections and thus avoid unnecessary waste of the cleaning belt. [Embodiment] As shown in the first and second figures, a schematic exploded perspective view and a combined plan view of a preferred embodiment of the fixed length transmission device of the present invention applied to a special cleaner for a fiber joint are disclosed. The fixed length transmission device (30) of the present invention is combined with a reel set (20) in a casing (1 〇) for constituting the cleaner, wherein: the outer casing ( 1 0 ) is formed by two casings (1 1 ) ( 1 2 ) opposite to each other, having a cleaning window (13) on one side and a notch (15) on the other side, the cleaning A fixing plate (1 4 ) having a perforation (1 4 1 ) is arranged at the window ( 13 ), and a sliding groove is arranged on the inner side wall of the outer casing (1 〇) 6 1288255, which is arranged at the cleaning window (1 3 ) There are slots.
