[0002] With the development of industrial automation and precision manufacturing technology, hard and brittle materials such as diamond, silicon carbide, and sapphire are increasingly used in electronics, aviation, medical and other fields. Due to their high hardness and strong wear resistance, these materials place higher demands on processing equipment and processes during the processing.

[0003] Traditional mechanical cutting methods are not only inefficient but also prone to defects such as cracks and chipping, which compromise the processing quality of hard and brittle materials. Laser cutting technology has emerged to improve the processing efficiency and quality of these materials. As a non-contact processing method, laser cutting offers advantages such as high cutting precision, a minimal heat-affected zone, and strong adaptability, making it an important tool for processing hard and brittle materials.

At the same time, due to the limitations of the clamping device, the material utilization rate and processing efficiency are often not high. Utility Model Content

[0061] A first rotating shaft 14 may be provided on the support rod 12, and a spring chuck 16 may be installed at one end of the first rotating shaft 14. In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The support rod 12 is provided with multiple first rotating shafts 14, which are parallel and spaced apart along the axial direction of the support rod 12.

This further improves the flexibility of angle adjustment of hard and brittle materials, thereby meeting the needs of multi-dimensional processing of complex angles.

[0068] See also Figure 4 The rotating plate 17 may include a lower plate 171 and an upper plate 173 arranged above the lower plate 171. A center hole is provided in the center of the lower plate 171. A limit pin 172 is provided in the center hole and is fixedly connected to the platform plate 10, which not only allows the lower plate 171 to rotate around the limit pin 172, but also limits the lower plate 171 by the limit pin 172 to prevent the lower plate 171 from moving upward. The upper plate 173 is fixedly connected to the lower plate 171 by bolts, and the support seat 11 is installed on the upper plate 173.

In order to facilitate the control of the rotation of the adjusting shaft 182, see Figure 3 A knob 183 is provided at one end of the adjusting shaft 182 away from the rotating plate 17.
