And, one side of the second blocking part 5 has a first inclined surface 10, and the other side has a second inclined surface 11, the first inclined surface 10 is located at the upper end of the second notch 9. And the second inclined surface 11 serves to take out the elastic member 2 from between the first stopper 4 and the second stopper 5.

The elastic member 2 is composed of a main body portion 12, a first elastic portion 7, and a second elastic portion 8. The first elastic part 7 is located between the first blocking part 4 and the second blocking part 5, the main body part 12 is provided with a through hole 13, and the second blocking part 5 is located in the middle of the through hole 13.

Meanwhile, one end of the elastic element 2 is a blocking end 14, the other end of the elastic element is a contact end 15, the blocking end 14 is arranged in the limiting groove 16, and the contact end 15 is arranged in the first notch 6.

One end of the through hole 13 is an a end, and the other end is a b end, and the a end is arranged in the second notch 9. The a-end is pushed into the second notch 9 by the first elastic portion 7.

The first elastic portion 7 is composed of a first bending surface 17 and a second bending surface 18, and an elastic region 19 is provided between the first bending surface 17 and the second bending surface 18. When the first and

second bending surfaces

17, 18 are compressed, the elastic region 19 is reduced, and the first elastic portion 7 is deformed, so that the contact end 15 can be removed from the first notch 6.

The middle of the connecting piece 3 is provided with a cavity 20, the optical fiber connector 1 is provided with an abutting surface 21, and the abutting surface 21 is contacted with the end surface of the connecting piece 3 to ensure that external impurities cannot enter.
