At this time, the pull ring handle 101 will push the contact side wall to move forward along the slide groove composed of the first card slot and the second card slot, thereby pushing the second contact protrusion 103 to move forward into the second card slot 302 and the third card slot 602, thereby locking the optical module and fixing the optical module on the host device. The reset spring 2 will apply elastic force to the spring hook 104 to prevent the contact protrusion from being disturbed by external force and thus prevent the locking state of the optical module from being destroyed; when the optical film block is pulled out from the interface of the host device, pull The pull ring handle 101 and the second contact protrusion 103 move backward to remove the optical module from the locked state. At this time, the optical module can be removed from the host device without restriction. When the optical device 5 is damaged, the optical module can be replaced by removing the screw 4, so that the installation and disassembly of the optical module are convenient and quick, and can be reused to save costs. The optical device 5 and the MPO interface 7 are firmly fixed inside the optical module through the first limit block 306, the second limit block 606, the first limit groove 304 and the second limit groove 605, and the optical module occupies less space, and can ensure that the utility model and the electronic device are stably connected, thereby ensuring the integrity and stability of data transmission.
