Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of wood carving processing, in particular to a wood carving processing tool. Background Art
[0002] As a traditional handicraft, wood carving is time-consuming from the selection of raw materials to the polishing process. In particular, the polishing process requires craftsmen to carefully carve, which makes the time cost of wood carving relatively high. In order to improve the efficiency of wood carving, wood carving tools are usually driven by motors. Therefore, the motors of handheld polishing tools also need to run for a long time, generating a large amount of heat, which affects the operation of the motor. The heat conduction to the hands will also cause further increase in hand sweat. On the other hand, the polishing piece usually polishes the wood carving by circular rotation. This rotation method will generate a large amount of wood chips and dust. Due to the high-speed rotation of the polishing piece and the splashing nature of the wood chips, these wood chips can easily splash near the operator's wrist and cover the wood carving. Therefore, it is meaningful to solve the above problems in actual processing. Utility Model Content
