Description
Technical Field
[0001] The utility model belongs to the technical field of guqin processing, and in particular relates to a guqin embryo assembling fixture. Background Art
[0002] Guqin, also known as Yaoqin, Yuqin and seven-stringed zither, is a traditional Chinese plucked string instrument with a history of more than 3,000 years. It belongs to the silk category of the eight musical instruments. Guqin has a wide range of tones, deep timbre and long lingering sound.
[0003] Putting the guqin together is a very important step in the process of making guqin. When putting the guqin together, glue is applied between the top and bottom boards, and then hemp rope is often used to tie the guqin body tightly, and then wooden wedges are inserted to increase the binding force. This is done until the glue solidifies and dries. However, this traditional method usually requires two people to work together to complete the assembling of the guqin, and great care must be taken during the tying process. If you are not careful, the top and bottom boards will be misaligned, which is very troublesome to operate.
