It is worth mentioning that the shape of the trough 110 is a gradually shrinking V shape from outside to inside, and the structure enables the outer surfaces of the carbon rods with different diameters to be propped against the two inner surfaces of the trough 110, so that the carbon rods with various diameters can be clamped by the clamping blocks 200 and the clamping seat 100, the applicability to the carbon rods is high, and the fixity of each carbon rod is good.
Based on the structure, the invention further improves and refines the structure.
As shown in fig. 2 to 5, the inner surface of the clamping block 200 opposite to the clamping seat 100 is connected with a hinge block 210, the hinge block 210 extends into the clamping seat 100 from the bottom of the clamping seat 100 and is hinged with the clamping seat 100 through a hinge shaft 120 arranged transversely, and the clamping block 200 can rotate relative to the clamping seat 100 in an upright plane with the hinge shaft 120 as a center, and the extending direction of the clamping seat 100 coincides with the upright plane.

That is, when the clamping block 200 rotates in a direction away from the trough 110, the torsion springs 140 accumulate force, and under the condition that the clamping block 200 has no external force, the acting forces of the two torsion springs 140 can rotate the clamping block 200 in the direction of the trough 110, in this case, the clamping block 200 can be not required to be manually pushed to rotate, and the use is convenient and labor-saving.
It should be noted that, although the clamping block 200 can automatically rotate to the initial position through the torsion spring 140, the carbon rod needs to be held during the rotation of the clamping block 200, so as to avoid the falling of the carbon rod.
As shown in fig. 1, 2, 4 and 5, a countersunk hole 150 is formed on an outer surface of one side of the material clamping seat 100, one end of the hinge shaft 120 has a shaft block 121, the other end is a threaded section 122, the hinge shaft 120 penetrates through the material clamping seat 100 and the hinge block 210 via the countersunk hole 150 and is in threaded connection with a nut (not shown), and the shaft block 121 abuts against the countersunk hole 150.
