The second inner peripheral surface 324 is adjacent to the second perforation 326, and the second cutouts 325 are communicated from the second outer peripheral surface 323 to the second perforation 326. In addition, each second outer peripheral surface 323 is conical, and When the two connecting portions 321 extend toward the second end portions 322, the outer diameter gradually decreases. The second cutouts 325 of each of the second bundle clamps 32 are spaced from each other by an angle of 90 degrees.

The locking unit 40 can position the first beam clamping base 20 and the second beam clamping base 30 on the positioning base 10, and can make the first inner side surface 211 and the first end surface 11 relatively approach, and can make the The second inner side surface 311 approaches the second end surface 12 relatively. The locking unit 40 has a plurality of first screws 41 penetrating through the first locking holes 213 and screwed into the first screw holes 14, and a plurality of bolts running through the second locking holes 313 and screwed into The second screws 42 in the second screw holes 16.

In addition, if the elastic first bundle clamp 22 does not need a first cut groove 225, it can simply be inserted into the corresponding first set of holes 13 with a complete cone and penetrate Pushing between the first outer side surface 212 and the inner side surface of the first set of holes 13 can also produce a clamping effect on the wire 4.

Furthermore, the second bundle clamp base 30 passes through the second screws 42 of the locking unit 40 through the second lock holes 313 and is screwed into the second screw holes 16 respectively, so that the second bundle clamps can be made. The pieces 32 are inserted into the second sets of holes 15 to generate positioning.
