[0002] A tuner is an auxiliary tool for musical instruments, primarily referring to electronic tuners used for tuning various stringed instruments, including guitar tuners, bass tuners, piano tuners, guqin tuners, ukulele tuners, etc. Tuners are electronic products that use a wavelength recognition program to display the pitch of an instrument. They are now widely used in tuning various instruments. Depending on the instrument they are used with, they are further categorized into guitar tuners, bass tuners, piano tuners, guqin tuning peg tuners, etc. Compared to traditional tuning tools (tuning flutes, tuning forks, etc.), they have advantages such as high accuracy, less susceptibility to weather conditions, and ease of operation. They are especially helpful for beginners of various instruments to quickly master the tuning techniques and improve their ability to distinguish pitch.

[0003] In practical use by those skilled in the art, existing tuners are normally clamped onto the guqin. During use, the clamps are easily damaged, and most of the clamps on the tuners are fixed with bolts. This requires tools to replace them, and the replacement is not convenient. Therefore, in order to address the above problems, a guqin tuning pegs tuning device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, current tuners are typically clipped onto the guqin. These clips are easily damaged during use, and most tuners are fixed with bolts.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-4 As shown, a tuning device for a guqin (a seven-stringed zither) includes a fixing clip 1, a fixing seat 2 fixedly connected to the top of the fixing clip 1, a tuner body 3 above the fixing seat 2, a connecting seat 4 at the bottom of the tuner body 3, a connecting component 5 at the bottom of the tuner body 3, the connecting component 5 being located inside the connecting seat 4, the tuner body 3 being connected to the fixing seat 2 through the connecting seat 4 and the connecting component 5, a movable groove 6 being provided inside the fixing seat 2, the connecting component 5 extending into the movable groove 6, and a limiting component 7 being provided inside the fixing seat 2, the limiting component 7 extending into the movable groove 6.

[0024] When in use, the fixing clip 1 can be clamped onto the guqin, and then the strings can be plucked to check if the pitch is accurate. If it is not accurate, adjustments can be made. If it is accurate, the next string can be plucked for adjustment. The connection component 5 and the limiting component 7 are designed to facilitate disassembly and installation.

[0025] Furthermore, the connecting assembly 5 includes a moving rod 501, a limiting sleeve 502, a hollow semi-circular head 503, a magnetic suction plate 504, and an arc-shaped ring 505. The moving rod 501 is located at the bottom of the tuner body 3 and extends into the interior of the connecting seat 4. The limiting sleeve 502 is fixedly connected to the interior of the connecting seat 4, and the moving rod 501 is slidably connected to the interior of the limiting sleeve 502. The hollow semi-circular head 503 is fixedly connected to one end of the moving rod 501. The magnetic suction plate 504 is fixedly connected to the outside of the moving rod 501, and the arc-shaped ring 505 is sleeved on the outside of the moving rod 501. The arc-shaped ring 505 is magnetically connected to the magnetic suction plate 504.

[0026] During operation, the connecting component 5 is used in conjunction with the limiting component 7.

[0027] Furthermore, the limiting assembly 7 includes a guide rod 701, a limiting head 702, a guide sleeve 703, and a spring 704. The guide rod 701 is slidably connected inside the fixed base 2, the limiting head 702 is fixedly connected inside the fixed base 2, the guide rod 701 is slidably connected inside the limiting head 702, the guide sleeve 703 is fixedly connected to one end of the guide rod 701 and is located inside the movable groove 6, and the spring 704 is sleeved on the outside of the guide rod 701 and is fixedly connected between the guide sleeve 703 and the limiting head 702.

[0028] During operation, when installing the tuner body 3, insert the hollow semi-circular head 503 into the movable slot 6. This allows the hollow semi-circular head 503 to meet the guide sleeve 703. Since the front of the hollow semi-circular head 503 is an arc surface and the contact surface of the guide sleeve 703 is a slope, there is no obstruction. The guide sleeve 703 is then compressed, and the spring 704 is compressed. The guide rod 701 moves inside the limiting head 702. Supported by the elasticity of the spring 704, after the guide sleeve 703 has moved past the arc surface of the hollow semi-circular head 503, the spring 704 pushes the guide sleeve 703 back to its original position. The back surface of the guide sleeve 703 then abuts against the back surface of the hollow semi-circular head 503, thus completing the installation. For disassembly, continue pressing the tuner body 3 until the arc-shaped ring 505 and the guide sleeve 703... The guide sleeve 703 features a double-sided arc design. With sufficient force, the guide sleeve 703 can pass through the arc-shaped ring 505. Pulling the tuner body 3 causes the force generated by the guide sleeve 703 to move the arc-shaped ring 505 until its front arc surface retracts into the hollow semi-circular head 503. With sufficient pulling force, the guide sleeve 703 moves along the arc surface of the arc-shaped ring 505. When the arc-shaped ring 505 retracts into the hollow semi-circular head 503, its arc surface connects with the arc surface of the hollow semi-circular head 503. This allows the guide sleeve 703 to pass through both the arc-shaped ring 505 and the hollow semi-circular head 503. At this point, the guide sleeve 703 loses its restraint, and the hollow semi-circular head 503 can be pulled out of the movable slot 6 for removal.

[0029] Furthermore, the fixing clamp 1 includes a first clamping plate 101, a second clamping plate 102 and a hinge assembly 103. The hinge assembly 103 is disposed on top of the first clamping plate 101, and the second clamping plate 102 is located above the first clamping plate 101. The second clamping plate 102 and the first clamping plate 101 are installed together by the hinge assembly 103.

[0030] During operation, the fixing clip 1 can be disassembled.

[0031] Furthermore, a pressing pad 104 is installed on one side of both the first clamping plate 101 and the second clamping plate 102;

[0032] When in use, the pressure pad 104 is designed to make the user more comfortable when pressing.

[0033] Furthermore, the hinge assembly 103 includes a rotating bracket 1031, a torsion spring connecting plate 1032, a rotating shaft 1033, a notch 1034, and a collar 1035. The two rotating brackets 1031 are symmetrically fixedly connected to the top of the first clamping plate 101, the torsion spring connecting plate 1032 is fixedly connected to the bottom of the second clamping plate 102, the rotating shaft 1033 is movably connected inside the two rotating brackets 1031, the torsion spring connecting plate 1032 is rotatably connected to the outside of the rotating shaft 1033, the notch 1034 is opened on the outside of the rotating shaft 1033, and the collar 1035 is sleeved inside the notch 1034.

[0034] During operation, the removed clamp 1 is divided into several parts. If one part is damaged, simply push the collar 1035 back into the notch 1034, ensuring that the outer diameter does not exceed the outer diameter of the rotating shaft 1033. This allows the rotating shaft 1033 to be pulled out from inside the rotating bracket 1031 and the torsion spring connecting plate 1032, thus separating the first clamp 101 from the second clamp 102. In this way, only the damaged part needs to be replaced after damage.

[0035] Furthermore, a clamping pad is fixedly connected to the opposite side of the first clamping plate 101 and the second clamping plate 102;

[0036] When in operation, the clamping pads provide a more secure hold.

[0037] Working principle: When using it, you can clamp the fixing clip 1 onto the guqin, then pluck the strings to see if the pitch is accurate. If it is not accurate, make adjustments. If it is accurate, pluck the next string to adjust.

[0038] During installation of the tuner body 3, the hollow semi-circular head 503 is inserted into the movable slot 6, so that the hollow semi-circular head 503 meets the guide sleeve 703. Since the front of the hollow semi-circular head 503 is an arc surface and the contact surface of the guide sleeve 703 is a slope, there is no obstruction. The guide sleeve 703 is then compressed, and the spring 704 is compressed. The guide rod 701 moves inside the limiting head 702. With the elastic support of the spring 704, after the guide sleeve 703 moves past the arc surface of the hollow semi-circular head 503, the spring 704 pushes the guide sleeve 703 back to its original position. At this time, the back surface of the guide sleeve 703 abuts against the back surface of the hollow semi-circular head 503, and the installation is completed. During disassembly, continue to press the tuner body 3 until the arc-shaped ring 505 meets the guide sleeve 703 and the guide sleeve 703... The double-sided arc design allows the guide sleeve 703 to pass through the arc-shaped ring 505 with sufficient force. Pulling the tuner body 3 then causes the guide sleeve 703 to move the arc-shaped ring 505 until its front arc surface retracts into the hollow semi-circular head 503. With sufficient pulling force, the guide sleeve 703 moves along the arc surface of the arc-shaped ring 505. When the arc-shaped ring 505 retracts into the hollow semi-circular head 503, its arc surface connects with the arc surface of the hollow semi-circular head 503. This allows the guide sleeve 703 to pass through both the arc-shaped ring 505 and the hollow semi-circular head 503. At this point, the guide sleeve 703 loses its restraint, allowing the hollow semi-circular head 503 to be pulled out of the movable slot 6 for removal, thus facilitating replacement.

[0039] The removed fixing clip 1 is divided into several parts. If one part is damaged, simply push the collar 1035 back into the notch 1034, ensuring that the outer part does not exceed the outer diameter of the rotating shaft 1033. This allows the rotating shaft 1033 to be pulled out from inside the rotating bracket 1031 and the torsion spring connecting plate 1032, thus separating the first clamping plate 101 from the second clamping plate 102. In this way, only the damaged part needs to be replaced after damage, thereby achieving cost savings.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
