As shown in fig. 2 and 4, the tail fiber holder 3 and the sample fiber holder 4 are flanged upward on the inclined side, and the flange is provided with a notch 31 for the tail fiber to pass through and a notch 421 for the sample fiber to pass through, so that the tail fiber and the sample fiber can be limited by the two notches.
