The invention discloses an ingot rod device for holding textile bobbins. The ingot rod device comprises a hollow rod body, openings formed in the rod body, three of more stretching and contracting components capable of stretching and contracting in the openings and a matched mechanism allowing the stretching and contracting components to stretch and contract. The stretching and contracting components comprise rods and are evenly distributed along the circumference, the matched mechanism makes the stretching and contracting component have the tendency of moving towards the interior of the rod body, and the ingot rod device further comprises a conical rod capable of being inserted into the rod body. The conical rod is inserted into the rod body, each stretching and contracting component moves toward the exterior of the rod body and exerts pressure on the inner wall of the corresponding bobbin continuously, and thus the function of folding the corresponding bobbin is achieved. By means of the ingot rod device, the bobbins different in inner diameter can be reliably fixed to a spindle, and normal operation of textile work can be maintained.
