[0023] Among them, the clamping plate 5 is slid in the limiting slide groove 4 to realize the movement and adjustment of the position of the clamping plate 5. When it is adjusted to a suitable position, the positioning bolt 6 on the back of the clamping plate 5 is rotated to limit and fix the position of the clamping plate 5, thereby improving the stability of the clamping plate 5 in clamping the workpiece. In addition, the setting of the limiting slide groove 4 enables four groups of clamping plates 5 to clamp and fix workpieces of different sizes, effectively improving the wide range of applications.
[0024] An adjusting component is arranged at the middle of the bottom end of the fixed plate 3, and the adjusting component includes a fixed seat 7, which is movably installed at the middle of the top end of the support column 2.

When the angle of the fixing plate 3 is tilted, the workpiece can be kept stable on the upper surface of the fixing plate 3, thereby effectively preventing the workpiece from falling off.
[0033] Then, the second servo motor 15 is started to drive the transmission gear 14 to rotate, and the transmission gear 14 can drive the outer gear ring 13 to rotate, so that the fixing seat 7 rotates on the top of the support column 2, and drives the fixing plate 3 to rotate, thereby realizing a 360-degree rotation adjustment of the angle of the clamped workpiece;
