Optical path coupling chip clamping device

The utility model relates to the technical field of chip clamping devices, and provides an optical path coupling chip clamping device, which is used for clamping a chip and comprises a fixed plate, a movable plate and at least one spring assembly, a first clamping head is arranged on the fixed plate, a second clamping head is arranged on the movable plate, and the first clamping head and the second clamping head are oppositely arranged and used for clamping the chip; and one end of the spring assembly is connected with the side surface of the fixed plate, and the other end of the spring assembly is connected with the side surface of the movable plate, so that the chip is clamped between the first chuck and the second chuck by stretching the spring assembly. The clamping device is simple in structure, stable and reliable in clamping and easy to adjust and maintain, the moving amplitude of the movable part and the fixed part is small in the adjusting process, and the problem that the requirement for clamping st
