[0036] See also Figure 4 、 Figure 5 and Figure 6 This embodiment provides a technical solution: a branching type optical splitter, including a storage portion 2, a fiber storage box 201 and a pressing cover 206:

[0037] A latch tooth 204 is provided inside the fiber storage box 201, and a pawl 207 is provided on the side of the pressing cover 206. The pawl 207 abuts against the latch tooth 204 and forms a ratchet structure. The ratchet structure can allow the rotating shaft 205 to rotate in only one direction.

The rotating shaft 205 will allow the vortex spring 209 to accumulate force while rotating to release the fiber line. At the same time, the pawl 207 set on the side of the pressing cover 206 is made to abut against the tooth 204 to form a ratchet structure, so that the rotating shaft 205 can only rotate in one direction, avoiding the rotating shaft 205 being driven to rotate by the vortex spring 209 after releasing the hand. When all the optical fiber lines wound in the storage slot 202 are pulled out, the optical fiber lines are not entangled on the rotating shaft 205, making the entire The storage portion 2 can move back and forth on the optical fiber line to change its position.
