However, the existing handicraft carving fixing devices have some obvious shortcomings.

[0003] Traditional handicraft carving fixing methods are often simple and extensive, and common simple clamps such as bench clamps are used to fix the handicrafts. This fixing method may work for handicrafts with regular shapes and relatively fixed sizes, but it is not effective for modern handicrafts with complex shapes, different sizes and asymmetric structures. For example, for handicrafts with irregular curved surfaces, unique shapes or asymmetric structures, traditional clamps cannot achieve all-around, close and stable fixation. During the carving process, the handicrafts are prone to displacement and shaking due to poor fixation, which not only seriously affects the precision of carving and leads to deviation of carved patterns or shapes, but also may cause damage to the handicrafts, increasing the production cost and the rate of defective products. Therefore, a handicraft carving fixing device is proposed to solve the above problems. CONTENT OF THE UTILITY MODEL
