The lens holder disc 1 and the swing arm needle 2 are both made of metal plates. The center of the lens holder disc 1 is provided with 1 central hole. In order to effectively reduce the optical path between the input collimator 4 and the output collimator 5 and prevent mutual interference between the input collimators 4 and the output collimators 5 of the same group, thereby increasing the insertion damage, the swing arm needle 2 is arranged on the front side of the mirror base plate 1, and the front end surface of the mirror base plate 1 is attached to the rear end surface of the swing arm needle 2. The fixed end of the swing arm needle 2 is positioned at the central hole of the lens base disc 1, and the free end of the swing arm needle 2 extends along the radial direction. The rotating shaft of the micro motor 3 is arranged in the central hole of the mirror base plate 1 in a penetrating way, and the fixed end of the swing arm needle 2 is fixed on the rotating shaft of the micro motor 3. The shape of the lens holder disc 1 can be set as required, and the lens holder disc can be designed into a rectangle, a trapezoid, a fan shape or a circle, so long as the requirement of the arrangement of the output holes can be met. In the present embodiment, the mirror base plate 1 has a semicircular shape. The center of the lens holder disc 1 is provided with 1 central hole. The center of the lens holder disk 1 is not strictly positioned at the center, and it only needs to satisfy the requirement of the arrangement of the output holes around the lens holder disk. In the present embodiment, since the mirror base plate 1 has a semicircular shape, the central hole of the mirror base plate 1 is opened at the center of the lower portion of the mirror base plate 1 in order to satisfy the arrangement of the peripheral output holes. The shape of the swing arm needle 2 is a long strip. In this embodiment, since the fixed end of the swing arm needle 2 needs to be connected with the rotating shaft of the micro motor 3, the width of the fixed end of the swing arm needle 2 is slightly larger than that of the free end of the swing arm needle 2.
The swing arm needle 2 is provided with 1 group of input holes. The group of input holes comprises more than 2 input collimation mounting holes which are all arranged in a straight line along the length direction of the swing arm needle 2.

In this embodiment, each set of output holes includes 6 output collimating mounting holes. An output collimator 5 is installed on each output collimation installation hole, and the tail fiber of the output collimator 5 faces the rear of the lens base disc 1. The included angle of the fan-shaped angle formed by every 2 adjacent groups of input holes on the lens holder disk 1 can be equal or unequal. In the present embodiment, in order to simplify the control of the micro motor 3, the sector angles formed by the input holes of every 2 adjacent groups on the seat disk are equal.

The input collimator 4 and the output collimator 5 may be single-core collimators or multi-core collimators, but the number of cores of the input collimator 4 and the output collimator 5 at the opposite positions is the same. In the present embodiment, the input collimator 4 and the output collimator 5 are all multi-core collimators selected to reduce the size of the device. In order to guide the path of the swing arm needle 2, the light transmission effect and the insertion loss increase caused by the alignment deviation between the group of input collimators 4 on the swing arm needle 2 and the group of output collimators 5 selected by the mirror base plate 1 due to the position deviation of the swing arm needle 2 are avoided; meanwhile, in order to avoid mutual interference between light emitted by each input collimator 4 on the swing arm needle 2, each output collimator 5 of a selected group on the lens holder disk 1 receives light emitted by an adjacent input collimator 4, so that the problems of mutual optical signal interference and increase of insertion loss are caused.
