[0015] The specific implementation of the present invention will be described in detail below by taking the regular quadrangular table sub-crystal chuck component as an example.
[0016] As attached Figure 1 ~ Figure 3 As shown, the sub-crystal chuck component for silicon rod drawing of the present invention is composed of sub-crystal 1 and chuck 2. The sub-crystal 1 includes a square-shaped connecting quadrangular table and a lifting rod 12, which are connected to the quadrilateral The upper table surface 13 of the table is larger than the lower table surface 14, the lifting rod 12 is arranged on the lower end surface of the lower table surface 14. The chuck 2 includes a threaded hole 21, a polygonal table hole 22 and a guide hole 23, a threaded hole 21, a polygonal table hole 22 It is a coaxial hole system with the guide hole 23, the cross-sectional shape of the polygonal frustum hole 22 is a quadrangular frustum, and the cone angle of the polygonal frustum hole 22 is 120°; th...
