[0002] The rapid development of the optical communications industry has also driven the upgrading of optical modules. In the current increasingly competitive optical communications market, there is an increasing demand for reduced device size and increased interface density in communication equipment. To meet this demand, optical modules are also moving towards highly integrated, small packages. However, the existing fixtures are complex in structure and difficult to operate, resulting in slow optical module coupling speeds and low coupling yields. As the production of optical modules increases, a fixture with a simple structure and easy processing is needed to facilitate optical module coupling, making the coupling operation simple, fast, and with a high coupling yield.

[0003] Existing technology, such as a fixture for coupling optoelectronic modules, has been published under the patent application CN201464680U. This fixture uses a fine-tuned five-axis translation stage to couple parallel optoelectronic modules. The fixture is simple to operate, securely attaches the adapter components to the circuit board, and allows for convenient and accurate coupling.

[0004] Currently, there is a lack of a device that can conveniently realize the positioning of the circuit board and the clamping of the adapter component, and realize the rapid coupling of the two by moving the adapter component. Utility Model Content
