Description

Technical Field

[0001] This utility model relates to the field of guzheng string-threading assistance technology, specifically a guzheng string-threading assistance device. Background Technology

[0002] The guzheng consists of a soundboard, bridges, strings, front nut, tuning pegs, tuning box, feet, back nut, side panels, sound hole, bottom board, and string holes. It has a rectangular wooden soundbox, the string frame is movable, and each string produces one note, arranged in a pentatonic scale.

[0003] After prolonged use, the tone of guzheng strings gradually deteriorates due to metal fatigue, and rust can occur due to the player's sweaty hands. At this point, the strings need to be replaced. Currently, the process involves the player threading the string through the threading hole and then winding it around the tuning peg. During this winding process, the player constantly pulls on the string. This prolonged pulling not only injures the hand but also causes the string to loosen over time, making the entire string replacement process too lengthy and inefficient.

[0004] Therefore, we propose a string-threading auxiliary device for the guzheng to solve the problems mentioned above. Utility Model Content
