[0036] Embodiment 1:

[0037] Please refer to Figures 1-6 , an anti-loosening zither string adjusting structure, which includes: a body connecting seat 1 and a string body 2, and further includes an adjusting and fixing mechanism 3 and a supporting mechanism 4. The string body 2 is arranged above the body connecting seat 1. An adjusting and fixing mechanism 3 for tensioning and fixing the string body 2 is arranged at the end of the body connecting seat 1. A supporting mechanism 4 for supporting the whole device is arranged below the adjusting and fixing mechanism 3;

[0038] Specifically, the adjusting and fixing mechanism 3 includes a control box 5, a first through hole 6, an adjusting component, a positioning component and a clamping component. Both ends of the body connecting seat 1 are fixedly connected with the control box 5. A first through hole 6 is opened at the top surface of the control box 5 at a position corresponding to the string body 2. The string body 2 passes downward through the first through hole 6 and extends into the control box 5.

[0039] Furthermore, the adjusting component includes a sleeve 8, a first knob 9, a movable rod 10 and an internal thread 11. The sleeve 8 is embedded and fixedly connected inside the control box 5 at a position corresponding to the string body 2. The end of the sleeve 8 is rotatably connected with the first knob 9. The movable rod 10 is slidably connected inside the sleeve 8. An internal thread 11 is opened on the outer side of the movable rod 10. The first knob 9 is threadedly connected with the movable rod 10 through the internal thread 11.

[0040] Further, the positioning component includes a fixed seat 12, a movable sleeve 13, elastic clamping pieces 14, and a second through hole 17. One end of the movable rod 10 is fixedly connected to the fixed seat 12. A second through hole 17 is formed in the middle of the fixed seat 12. The inner wall of the second through hole 17 is beveled. A movable sleeve 13 is arranged inside the second through hole 17. Four elastic clamping pieces 14 are annularly arranged above the movable sleeve 13. The movable sleeve 13 and the elastic clamping pieces 14 are movably connected to the fixed seat 12 through the second through hole 17. The string body 2 extends to the inside of the movable sleeve 13 and the elastic clamping pieces 14.

[0041] Further, the clamping component includes a second knob 15, a connecting rod 16, and a cam 18. A second knob 15 is arranged on the outer side of the end of the fixed seat 12 away from the movable rod 10. A connecting rod 16 is rotatably connected inside the fixed seat 12. The connecting rod 16 is fixedly connected to the second knob 15. The connecting rod 16 passes through the movable sleeve 13 and extends to the inside of the movable sleeve 13. One end of the connecting rod 16 away from the second knob 15 is fixedly connected to a cam 18. The protruding end of the cam 18 is in close contact with the inner bottom surface of the movable sleeve 13.

[0042] Further, a cover plate 7 is arranged at one end of the control box 5 away from the piano body connecting seat 1. The cover plate 7 is snap-connected to the control box 5.

[0043] It can be known that by rotating the first knob 9, the movable rod 10 can be driven to move along the sleeve 8. While the movable rod 10 is moving, the string body 2 fixed to it can be stretched, thereby realizing the adjustment of the tightness of the string body 2. When the string body 2 is worn or broken, the second knob 15 can be rotated to drive the connecting rod 16 and the cam 18 to rotate, so that the protruding end of the cam 18 is separated from the inner bottom surface of the movable sleeve 13, so that the movable sleeve 13 loses the downward force, and then the elastic limit of the movement of the string body 2 is released through the elasticity of the elastic clamping pieces 14. When the string body 2 is replaced, the string body 2 is extended to the inside of the movable sleeve 13 and the elastic clamping pieces 14 again, and the second knob 15 is rotated in the opposite direction, so that the protruding end of the cam 18 contacts the movable sleeve 13 again, so that the movable sleeve 13 and the elastic clamping pieces 14 obtain a downward force, and then the elastic clamping pieces 14 annularly hold the string body 2 through the inclined design of the inner wall of the second through hole 17, thereby completing the movement limit of the string body 2.
