Optical fiber coupler capable of efficiently outputting

The utility model belongs to the technical field of optical fibers, in particular to an optical fiber coupler capable of efficiently outputting, and provides the following scheme: the optical fiber coupler comprises a base, the top of the base is fixedly connected with a first supporting plate, the side surface of the first supporting plate is meshed with a threaded rod, and the surface of the threaded rod is meshed with a first sliding block; the side face of the first sliding block is slidably connected with a first sliding groove. According to the utility model, through the arrangement of the disc, when the electric generator drives the disc to rotate, the oscillating rod is driven to rotate, and at the moment, the second sliding block fixedly connected with the oscillating rod slides left and right under the action of the concave plate and drives the concave plate to slide up and down; when the concave plate slides, the gear is driven to rotate under the action of the rack and the rotating plate is driven
