[0002] Existing string adjustment devices mainly rely on manual adjustment, depending on the rotation of the tuning pegs to control the string tension. This method is not only laborious but also makes fine-tuning the strings difficult. To address these issues, existing designs, such as the automatic guitar tuner disclosed in Chinese CN206541604U, not only enable automatic tuning but also feature function selection and display. Another example is the fine-tuning tuning pin disclosed in CN101868820B, which can be fixed to the string instrument with minimal impact and allows for simplified fine-tuning. However, these designs are all single-mode adjustments and cannot combine motor-driven and manual adjustments. Utility Model Content

Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. In addition, for clarity and brevity, descriptions of known functions and structures are omitted in the embodiments.

[0019] It should be understood that the phrase "an embodiment" or "this embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "an embodiment" or "this embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0020] Furthermore, reference numerals and / or letters may be repeated in different examples within this application. Such repetition is for the purpose of simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or settings discussed.

[0021] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, B exists alone, and A and B exist simultaneously. The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0022] In this article, the term "at least one" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, "at least one of A and B" can mean: A exists alone, A and B exist simultaneously, or B exists alone.

[0023] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion.

[0024] Example 1: Please refer to Figures 1-6 This embodiment mainly introduces a dual-control fine-tuning string shaft, characterized in that it includes a string handle, a bottom fixing bracket 1, a shift gear set, a motor fixing bracket 6, a motor, and a housing 5; The modified gear set is located at the top of the shank; The motor is mounted on top of the shift gear set via a motor mounting bracket 6; The shift gear set, motor mounting bracket 6, and motor are all located inside the housing 5; The bottom fixing bracket 1 is located on the outside of the string handle and is engaged with the outer casing 5.

[0025] Furthermore, the modified gear set includes: a top mechanical control gear 7, a gear bearing plate 8, a first accompanying gear set 9, a second accompanying gear set 10, a fixed gear 11, and a driven gear 12; The first accompanying gear set 9 is disposed inside the gear bearing disk 8; The top mechanical control gear 7 is located in the middle of the gear bearing plate 8 and meshes with the first accompanying gear set 9; the top of the top mechanical control gear 7 is connected to the rotating shaft of the motor; The second accompanying gear set 10 is disposed at the bottom of the gear bearing disk 8; The fixed gear 11 and the driven gear 12 respectively mesh with the second accompanying gear set 10; The fixed gear 11 and the driven gear 12 are nested on the shank; the fixed gear 11 is located on top of the driven gear 12.

[0026] The motor is fixed to the top mechanical control gear 7. The rotation of the top mechanical control gear 7 drives the first accompanying gear set 9 to rotate. The rotation of the first accompanying gear set 9 drives the gear bearing disk 8 to rotate, and the rotation of the gear bearing disk 8 drives the second accompanying gear set 10 to rotate. The second accompanying gear set 10 meshes with the fixed gear 11 and the driven gear 12 at the same time. Since the fixed gear is fixedly connected to the bottom fixed rod 4, the fixed gear 11 and the driven gear 12 have a certain gear difference. Therefore, the second accompanying gear set 10 rotates around the fixed gear 11, while the fixed gear 11 does not rotate. However, due to the gear difference between the fixed gear 11 and the driven gear 12, the driven gear will rotate, thereby driving the string fixing rod 3 in the string arm to rotate. The rotation of the string fixing rod 3 will drive the string to rotate, thus realizing the motor drive.

[0027] Meanwhile, this application also uses the outer shell and the bottom fixing frame 1 as a fixed connection. Since the outer shell is limited by the motor fixing frame 6, the rotation of the outer shell will drive the motor to move as a whole, that is, the shaft and the motor move as a whole. The rotation of the shaft will drive the first accompanying gear set 9 to rotate. The rotation of the first accompanying gear set 9 will drive the string fixing rod 3 to rotate, thereby realizing manual rotation.

[0028] Furthermore, the truss handle includes: a bottom fixing rod 4, a string fixing rod 3, and an upper fixing rod 2; The upper fixing rod 2 is nested on the chord fixing rod 3; The string fixing rod 3 is nested on the bottom fixing rod 4; The bottom fixing frame 1 is nested on the upper fixing rod 2 and is fixedly connected to the outer shell 5 by buckles.

[0029] Furthermore, the fixed gear 11 is engaged with the bottom fixed rod 4; The driven gear 12 is engaged with the chord fixing rod 3; The fixed gear 11 is located above the driven gear 12, and both the fixed gear 11 and the driven gear 12 mesh with the second accompanying gear set 10.

[0030] Furthermore, a raised ring 13 is provided at the top of the upper fixing rod 2, and the diameter of the raised ring 13 is larger than the diameter of the bottom fixing frame 1.

[0031] Furthermore, a battery is also provided inside the outer casing 5, and the battery is connected to the motor; A switch is also provided on the outer casing 5, and the switch is located between the battery and the motor.

[0032] Furthermore, the first accompanying gear set 9 includes three evenly distributed gears fixed within the gear carrier disk 8.

[0033] This application discloses a dual-control fine-tuning tuning pin, comprising a tuning handle, a bottom mounting bracket, a shifting gear set, a motor mounting bracket, a motor, and a housing. The shifting gear set is located on top of the tuning handle. The motor is mounted on top of the shifting gear set via the motor mounting bracket. The shifting gear set, motor mounting bracket, and motor are all housed inside the housing. The bottom mounting bracket is located on the outside of the tuning handle and engages with the housing. Through this design, this application enables dual adjustment modes of electric automatic and manual operation, thereby allowing for different control switching of the strings.
