[0002] The guzheng, a gem of traditional Chinese musical instruments, occupies an extremely important position in the music field and is deeply loved by music lovers and professional performers alike. It is widely used in various musical performance forms such as solo, ensemble, and accompaniment. In the daily use and maintenance of the guzheng, the string adjustment structure plays a crucial role, and its performance directly affects the pitch stability and playing effect of the guzheng.

[0003] Reference patent (Publication No.: CN217719006U; Publication Date: 2022-11-01) discloses an anti-loosening adjustment structure for guzheng strings, relating to the field of guzheng musical instrument technology. It includes a body connecting seat, with an adjustment connecting cover at one end. An adjustment component is located between the inner side of the adjustment connecting cover and the body connecting seat. An adjustment partition frame is located on the outer side of the adjustment component. A locking component is located between the upper end of the adjustment partition frame and the adjustment connecting cover. Multiple string bodies are located at the upper end of the body connecting seat. A fixing partition is fixed between the inner side of the body connecting seat and the adjustment partition frame. Through the structural design of the adjustment component, the string bodies are prevented from loosening again after the tension adjustment is completed. A limiting rod at one end of the connecting block locks and fixes the adjustment shaft, thus preventing the string bodies wound around the winding shaft from loosening due to rotation.

[0004] Based on the aforementioned patents, although the string adjustment structure can effectively adjust the tension of the strings, the strings are prone to wear or breakage after prolonged use. However, the string installation method of some structures is relatively complicated, and when the strings break and need to be replaced, a cumbersome disassembly process is often required. Furthermore, during long-term use, the main string body and adjustment structure inside the body connector of the guzheng are easily affected by the external environment. Dust, debris, and other contaminants can easily enter the body connector and adhere to the strings and adjustment components, which not only affects the vibration and tone of the strings but may also cause wear and jamming of the adjustment structure, reducing the flexibility and accuracy of adjustment. Therefore, this utility model provides a guzheng string adjustment structure that can prevent loosening. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a guzheng string adjustment structure that prevents loosening.
