Bevel clamping piece anchoring device

The utility model relates to an oblique section clamping piece anchoring device. The length alpha of an anchor sleeve barrel is from 35 to 45 mm, the diameter phi of an excircle is from 25 to 30 mm, and the diameter phi 2 of the base circle of the inner chamber of the sleeve barrel is from 20 to 25 mm; the diameter phi 3 of the tip circle is from 10 to 15 mm. A clamping piece is an arc-shaped cone body of which the length is equal to the length of the sleeve barrel, the radius R 1 of the outer circular arc at the bottom end is from 9 to 12 mm, the radius R 2 of the outer circular arc at the top end is from 6 to 8 mm, and the radius 3 of the full-length inner circular arc is from 3 to 5 mm. An inner cambered surface is uniformly provided with transverse direction screw threads, and the bottom end of an outer cambered surface is provided with a transverse direction groove. Both longitudinal sides of the clamping piece is cut into two mutual and crossed oblique sections, and the sleeve barrel is sheathed on a stranded wire; the clamping piece is embedded between the stranded wire and the sleeve barrel, and thus, the stretching force of the stranded wire can be jointly accepted.
