Abstract

PURPOSE: To prevent a crystal seed from falling away from the titled device and enable the cryatal to be easily centered with the device by attaching a protruded wall to the bottom of a pulling rod to form a crystal seed holding section and screwing a plurality of predetermined crystal supporting members in the wall.
CONSTITUTION: Continuous protruded wall 2 is formed at the bottom periphery of pulling rod 1, and the part enclosed by wall 2 is used as crystal seed holding section 3. Four crystal supporting members 4 are attached to wall 2 at the same angle. Each member 4 is composed of screw 5, pressing plate 6 and rotating handle 7, and by rotating handle 7, plate 6 is drawably screwed on wall 2 toward the center of rod 1. Thus, crystal seed 8 can be supported by plates 6.
