[0019] Among them, the through groove 8 horizontally penetrates the fixed plate 4, and the size of the through groove 8 is equal to the size of the limiting member 7; it is convenient for the limiting member 7 and the through groove 8 to cooperate to limit the fixed plate 4.

[0020] Among them, a connecting groove 11 is opened at one end of the connecting plate 5 away from the fixed plate 4, the connecting groove 11 penetrates the connecting plate 5, and the connecting groove 11 extends into the inside of the sleeve 1; it is convenient for the plug 6 to connect the connecting plate 5 and the sleeve 1 together.

[0021] Among them, a washer 13 is arranged inside the groove 12. One side of the lens 17 away from the front cover 2 is attached to the washer 13, and the washer 13 is made of rubber material; this is convenient for improving the stability of the lens 17 in the groove 12 and preventing the lens 17 from shaking.

[0023] The working principle and usage process of the present utility model: When it is necessary to disassemble the fiber optic collimator, first rotate the limiting member 7 so that the rotating shaft 10 rotates on the bottom plate 9 until the angle of the limiting member 7 is equal to the angle of the through groove 8. Then, people remove the pin 6 on the connecting plate 5 and separate the pin 6 from the sleeve 1 and the connecting plate 5. At this time, the elastic member 14 arranged between the sleeve 1 and the fixed plate 4 will automatically reset, thereby pushing the fixed plate 4 with the optical fiber body 3 away from the sleeve 1. And people can directly remove the optical fiber body 3 and the fixed plate 4. If the limiting member 7 is not rotated to the same angle as the through groove 8, then the elastic member 14 will not be able to separate the fixed plate 4 and the sleeve 1. Only after both the fixed plate 4 and the connecting plate 5 are released from the limit can the optical fiber body 3 and the sleeve 1 be separated. After the optical fiber body 3 and the sleeve 1 are separated, rotate the front cover 2 and separate the front cover 2 from the sleeve 1 through the processed thread. At this time, the lens 17 placed inside the groove 12 can be removed, thus facilitating people to inspect and repair the inside of the through hole 15 and the optical fiber.
