By adopting the way of rotational connection of the connecting rods, the synchronous movement of the unlocking push block 5 and the belt 1 is realized, and they approach or move away from the circular shaft 10 at the same time. When the belt 1 is pulled, the unlocking push block 5 is unlocked, which is convenient to use.

[0026] The symmetric L-shaped clamping plates 19 are respectively fixedly connected to a pressing plate 2. To achieve the protection of the unlocking push block 5 and the like.

[0027] The symmetric cylinders 13 are respectively fixedly connected to one end of a holding spring 14. By adopting the holding spring 14, the position of the unlocking push block 5 is maintained, and the push block 6 is kept away from the elastic piece.

[0028] The working principle of a belt-pulling unlocking device for an optical module provided by the present utility model is as follows:

[0029] Pull the belt 1, the belt 1 moves along the area formed by the base 3 and the L-shaped clamping plates 19, drives the square block 12 to move, the square block 12 drives the outer connecting rod 11 to swing, the outer connecting rod 11 drives the middle connecting rod 9 to swing, the middle connecting rod 9 drives the cylinder 13 to swing, the cylinder 13 drives the inner connecting rod 8 to swing, the cylinder 13 drives the holding spring 14 to move, stretches the holding spring 14, the inner connecting rod 8 drives the rectangular block 4 to move, the rectangular block 4 drives the unlocking push block 5 to move along the area formed by the base 3 and the L-shaped clamping plates 19, and the unlocking push block 5 drives the push block 6 to move, and the push block 6 pushes the elastic piece on the interface cage to realize module unlocking. After removing the external force, the holding spring 14 restores, and the unlocking push block 5 resets.

[0030] Embodiment 2: This embodiment is further elaborated on the basis of Embodiment 1. The pressing plate 2 is fixedly connected to two guide cylinders 15. A positioning spring 16 and a guide rod 17 are respectively arranged in the two guide cylinders 15. The symmetric guide rods 17 are respectively fixedly connected to one end of the corresponding positioning spring 16, the symmetric guide cylinders 15 are respectively fixedly connected to the other end of the corresponding positioning spring 16, and the symmetric guide rods 17 are respectively fixedly connected to the hemispheres 18.

[0031] The unlocking push block 5 is provided with a positioning groove 7, and the hemisphere 18 matches the positioning groove 7. By adopting the hemisphere 18 and the positioning groove 7, it is realized to keep the push block 6 pushing the elastic piece on the interface cage and prevent the pulling belt 1 from detaching from the area composed of the base 3 and the L-shaped clamping plate 19.

[0032] The positioning groove 7 adopts an inferior arc spherical groove. It is convenient to realize that when pulling the pulling belt 1, it is convenient for the hemisphere 18 to disengage from the positioning groove 7.

[0033] The working principle of a pull - type unlocking device for an optical module provided by the present utility model is as follows:

[0034] In the initial state, Figure 1 the right - hand hemisphere 18 in the middle is in the positioning groove 7. When the unlocking push block 5 moves, it squeezes the hemisphere 18, causing it to move upward. The hemisphere 18 drives the guide rod 17 to move along the guide cylinder 15, squeezing the positioning spring 16 until the hemisphere 18 contacts the plane of the unlocking push block 5, keeping the positioning spring 16 squeezed. When the positioning groove 7 matches the left - hand hemisphere 18, the left - hand positioning spring 16 recovers, causing the hemisphere 18 to gradually enter the positioning groove 7 until the hemisphere 18 completely enters the positioning groove 7 and the resistance increases, then stop pulling the pulling belt 1. When resetting the unlocking push block 5, push the pulling belt 1 in the reverse direction to make the right - hand hemisphere 18 in the positioning groove 7.

[0035] The above are only the embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
