The elongated member 100 can be pulled out of the mounting hole 2 by unlocking the locking structure 3, thereby rapidly achieving the unlocking process of the elongated member 100. The plurality of mounting holes 2 are provided at the first interval L, and the elongated members 100 are fixed in the different mounting holes 2, so that the size of the mounting interval between the elongated members 100 can be flexibly adjusted, and different use demands can be satisfied.

For example, on an osteoporotic patient's bone, two mounting holes 2 at a relatively large distance may be selected for mounting the bone pins to prevent stress fracture problems when the bone pins are implanted into the bone.
