The present invention relates to a fiber cleaning device, and more particularly to a fixed length fiber cleaning device.

When the optical fiber is connected to the connector through the optical fiber connector, in order to ensure that the connection portion is not affected by foreign matter, the optical fiber connector must be cleaned by the optical fiber cleaning device before the optical fiber connector is connected with the connector.

The structure of the existing optical fiber cleaning device is mainly provided in a hollow casing, which is provided with a fiber cleaning tape roll which is wound by a long optical fiber cleaning tape, and the casing is further provided with a rotating retracting mechanism, rotating The retracting mechanism is connected to the end of the optical fiber cleaning tape, and the user can rotate the rotating retracting mechanism to drive the unused optical fiber cleaning tape segment to move to the cleaning port of the casing, and extend the optical fiber connector to the cleaning port in the optical fiber cleaning tape After wiping, the used fiber cleaning tape section can be transferred to another space in the casing by the rotating retracting mechanism.

However, the prior optical fiber cleaning device still provides an easy-to-use optical fiber cleaning device for the user. However, the optical fiber cleaning device uses a rotating retracting mechanism to provide user rotation to move the unused optical fiber cleaning tape segment to the casing. The cleaning port, during the operation, it is difficult for the user to control the length of the rotating retracting mechanism to drive the optical fiber cleaning belt to the cleaning port of the casing. If the rotating retracting mechanism drives the optical fiber cleaning belt to have a small moving length, some of the used optical fiber cleaning tape segments are still located at the cleaning opening, resulting in repeated wiping of the used optical fiber cleaning tape to contaminate the result, which is disadvantageous for the user. For the cleaning operation of the optical fiber connector; if the rotating retracting mechanism drives the optical fiber cleaning tape to move for a long time, the optical fiber cleaning tape cannot be fully utilized, and there is a problem of wasted material.

The main purpose of this creation is to provide a fixed length optical fiber cleaning device that solves the problem that the existing optical fiber cleaning device cannot be fixed length.

In order to achieve the foregoing, the fixed length optical fiber cleaning device proposed by the present invention comprises: a casing having an activity chamber, a receiving chamber and a storage chamber between the movable room and the accommodating chamber.
