Description

Multifunctional plane micro-engraving console

technical field

The invention relates to micro-engraving operating equipment, in particular to a multifunctional flat micro-engraving operating table.

Background technique

Micro-carving is one of the most mysterious and precious art varieties in Chinese culture, which has been called "stunt skill" in the past dynasties. However, there are very few people engaged in miniature sculpture art, and this Chinese intangible cultural heritage is facing the risk of being lost. The reason is that in terms of micro-carving skills, it is not easy to get started, and it is difficult to get started. Micro-carving needs to be practiced beyond ordinary people's concentration. It takes at least 3 to 5 years for beginners to master basic skills, or even longer.

There are three most basic problems in micro-carving technology: hanging elbow carving and material fixing, namely: 1. The problem of hanging elbow carving: the traditional way of micro-carving is to hold the fixture firmly with the left hand under the microscope, place it on a fulcrum, and hang the elbows with both hands. For engraving, because the two arms are not supported, it is difficult to control the vibration of the arms. It is difficult to perform fine work, the speed is slow, and the error is large; 2. The problem of material fixing: the material needs to be fixed during micro-carving. If the material is not fixed well, it cannot be carved. Fixtures are the only tool for fixing micro-engraving materials. Traditional micro-carving fixtures, except for the wooden or bamboo clips commonly used for small works, mostly need to make special fixtures according to the size, shape, thickness and other shapes of the material, almost one object and one clip, different shapes and different clips, There are a large number of fixtures, which are cumbersome to make and stored in piles.

In addition, micro-carving requires a highly quiet state of mind and body and an external environment: when a sculptor is used to micro-carving, he looks down at the original text or picture at hand, and then raises his head to engrave on the microscope. There is movement and stillness, frequent movements, which will inevitably lead to word loss , Missing sentences, and crossing lines directly affect the quality of micro-carving works, and even waste all previous efforts.
