By setting the clamping assembly 12, specifically, the upper clamping seat 121 is pressed downward, and when it contacts the silicon-molybdenum rod, the bolt 232 is rotated to drive the push block 233 to move and push the extrusion block 253, then the vertical rod 125 drives the upper clamping seat 121 to move downward to clamp the silicon-molybdenum rod and fix it, so that the silicon-molybdenum rod can be quickly fixed, and the bolt 232 is rotated in the opposite direction to make the push block 233 leave the extrusion block 253, then the upper clamping seat 121 is reset upward by the elastic action of the spring 252, so that the silicon-molybdenum rod can be quickly released and the work efficiency is improved.
