[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. When optical fiber is connected to optical equipment, high connection accuracy and reliability must be guaranteed. In the prior art, in order to prevent the male and female heads of the optical fiber connection structure from changing their relative positions under external interference after connection, a generally adopted measure is to add a bolt sleeve to the male head and fix it to the female head through threads. However, even so, the male and female heads are still prone to slight changes in relative position under the influence of machine vibration. For example, the male and female heads rotate relative to each other by a certain angle, resulting in reduced accuracy of optical fiber transmission and coupling problems in severe cases.

[0004] In the prior art, a number of limiting protrusions and limiting grooves are added, which effectively solves the problem that the male and female heads are still prone to slight changes in relative position under the influence of machine vibration.
