[0023] When working, the guzheng strings are connected to the string axis 7 through the rear Yueshan 2, the zither code 4 and the front Yueshan 3. The tuning is performed through the tuning component 8, which does not interfere with each other and can effectively prevent accidental collision during tuning. At the same time, the limit component 9 can facilitate the installation and disassembly of the tuning component 8.

[0024] Furthermore, the tuning assembly 8 includes a fixed plate 801, a plurality of movable rods 802 and a plurality of shaft sleeves 803. The fixed plate 801 is arranged inside the zither head cavity 5. The plurality of movable rods 802 are uniformly slidably connected inside the fixed plate 801. The plurality of shaft sleeves 803 are respectively fixedly connected to one end of the corresponding movable rod 802.

[0025] During operation, push the movable rod 802 so that the movable rod 802 will move inside the fixed plate 801, so that the shaft sleeve 803 can be sleeved on the outside of the corresponding string axis 7, and then rotate the movable rod 802 to drive the shaft sleeve 803 to rotate, so that the tightness of the string can be adjusted, thereby tuning. After the tuning is completed, pull the corresponding movable rod 802 so that the shaft sleeve 803 will be separated from the string axis 7, and then operate the next movable rod 802 to tune. In this way, each movable rod 802 corresponds to a string axis 7. After tuning, the corresponding shaft sleeve 803 will be away from the corresponding string axis 7, so that there is no interference with each other, which can effectively prevent accidental collision during tuning.

[0026] Further, the limiting assembly 9 includes a rotating shaft rod 901, a spring 902, a limiting rod 903, a spring 904 and a connecting rope 905, the rotating shaft rod 901 is rotatably connected to the inside of the fixed plate 801, one end of the spring 902 is fixedly connected to the outside of the rotating shaft rod 901, a movable groove 10 is provided on the top of the fixed plate 801, the limiting rod 903 is movably connected to the inside of the movable groove 10, the spring 904 is fixedly connected to the inside of the movable groove 10, and the spring 904 is fixedly connected to the bottom of the limiting rod 903, the connecting rope 905 is fixedly connected to the outside of the rotating shaft rod 901, and one end of the connecting rope 905 is fixedly connected to the bottom of the limiting rod 903;

[0027] During operation, when removing the tuning component 8, it is only necessary to pull the spring 902, so that the spring 902 will drive the rotating shaft rod 901 to rotate, and the connecting rope 905 will be wrapped around the outside of the rotating shaft rod 901. At this time, the connecting rope 905 will pull the limit rod 903 downward, so that the limit rod 903 compresses the spring 904 and moves it out of the interior of the tuning component 8, thereby retracting it into the interior of the movable groove 10. In this way, the tuning component 8 loses its limit and can be removed. When installing, the spring 902 is also pulled to pull the limit rod 903 to the interior of the movable groove 10, and then the tuning component 8 is inserted into the interior of the zither head cavity 5, and then the spring 902 is loosened. Then when the limit rod 903 meets the limit hole 6, the spring 904 restores its deformation and pushes the limit rod 903 to be stuck in the interior of the limit hole 6 for limiting.

[0028] Furthermore, the limiting rod 903 fits with the limiting hole 6, and the limiting rod 903 extends to the inside of the limiting hole 6;

[0031] During operation, the handle 11 is adjusted to facilitate the rotation of the movable rod 802 .

[0032] Furthermore, a slide groove 12 is provided inside the fixed plate 801, and a slide plate 13 is fixedly connected to the outside of the movable rod 802, and the slide plate 13 is slidably connected inside the slide groove 12;

[0033] This allows the movable rod 802 to move smoothly during operation.

[0034] Furthermore, one end of the clockwork spring 902 extends to the outside of the fixed plate 801, and one end of the movable rod 802 located outside the fixed plate 801 is fixedly connected to the limited position handle 14;

[0035] During operation, the limiting handle 14 can be used to conveniently pull the mainspring 902 and effectively prevent the mainspring 902 from retracting into the interior of the fixing plate 801 .

[0036] Working principle: the strings of the guzheng are fixed on the string axis 7. When tuning, push the movable rod 802 so that the movable rod 802 will move inside the fixed plate 801, so that the shaft sleeve 803 can be sleeved on the outside of the corresponding string axis 7, and then rotate the movable rod 802 to drive the shaft sleeve 803 to rotate, so that the tightness of the string can be adjusted, so as to tune. After the tuning is completed, pull the corresponding movable rod 802 so that the shaft sleeve 803 will be separated from the string axis 7, and then operate the next movable rod 802 to tune. In this way, each movable rod 802 corresponds to a string axis 7. After tuning, the corresponding shaft sleeve 803 will be away from the corresponding string axis 7 and will not contact, so there is no interference. When disassembling the tuning component 8, you only need to pull the trigger. When the mainspring 902 is installed, the mainspring 902 will drive the rotating shaft rod 901 to rotate, and the connecting rope 905 will be wound around the outside of the rotating shaft rod 901. At this time, the connecting rope 905 will pull the limiting rod 903 downward, and the limiting rod 903 compresses the spring 904 and moves it out of the interior of the tuning component 8, thereby retracting it into the interior of the movable groove 10. In this way, the tuning component 8 loses its limit and can be removed. When installing, the mainspring 902 is also pulled to pull the limiting rod 903 to the interior of the movable groove 10, and then the tuning component 8 is inserted into the interior of the zither head cavity 5, and then the mainspring 902 is loosened. When the limiting rod 903 meets the limiting hole 6, the spring 904 recovers its deformation and pushes the limiting rod 903 to be stuck in the interior of the limiting hole 6 for limiting.

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
