Variable-diameter prestressing tendon traction structure

The utility model discloses a variable-diameter prestressing tendon traction structure, belongs to the technical field of prestressing tendon anchoring, and solves the problem that an anchor plate can be mounted only by manually carding prestressing tendons after the conventional prestressing tendon traction and reeving. The device comprises a conversion shaft core and conversion shaft pieces, the conversion shaft core and the conversion shaft pieces are each provided with a hole position used for cable penetrating, the conversion shaft pieces are of a multi-piece structure, and an expansion structure capable of driving the conversion shaft pieces to move in the radial direction so as to unfold prestressed tendons is arranged between the conversion shaft core and the conversion shaft pieces. And a hoisting assembly which is detachably connected with the conversion shaft piece, the conversion shaft core and the prestressed tendons at the same time is arranged above the conversion shaft piece. According to the
