DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and examples. The embodiments of the present invention include but are not limited to the following examples.

[0021] Example 1: like Figure 1-10As shown, the violin tuner provided by the present invention includes: a clamping mechanism, a detection mechanism and a holding mechanism; the clamping mechanism includes a columnar support member 1, two clamping blocks 2 are symmetrically and radially slidably installed on the top of the support member 1, and an adjusting tube 3 is threadedly installed on the support member 1. The adjusting tube 3 is rotated to move it axially along the support member 1, so that the two clamping blocks 2 can be brought close to each other. When the violin's string axis is located between the two clamping blocks 2, the two clamping blocks 2 can be brought close to each other through the adjusting tube 3 to fix the string axis between the two clamping blocks 2. The detection mechanism includes a connecting shaft 4 mounted on one end of a support member 1, with a rotating shaft 5 mounted between the connecting shaft 4 and the support member 1. The rotating shaft 5 allows the connecting shaft 4 to be rotatably connected to the support member 1. A torsion spring 6 is mounted on the rotating shaft 5, with the ends of the torsion spring 6 fixedly connected to the connecting shaft 4 and the support member 1, respectively. A ring-shaped angle ruler 7 is fixedly mounted on one end of the support member 1, and a pointer 8 is fixedly mounted on the outer wall of the connecting shaft 4. When the connecting shaft 4 and the support member 1 rotate relative to each other, the torsion spring 6 deforms and causes the pointer 8 to deflect. Since the parameters of the torsion spring 6 are known, the magnitude of the torque can be calculated from the deflection angle of the pointer 8. This principle is similar to that of a torque wrench and will not be elaborated here. Therefore, the maximum deflection angle of the pointer 8 (the safety threshold) can be calculated based on the tension that the strings can withstand, and a red mark is placed on the corresponding position of the angle ruler 7. When the pointer 8 deflects no more than this angle, the strings will not break. A gripping mechanism is mounted at the end of the connecting shaft 4 to facilitate manual rotation of the connecting shaft 4. During use, align the end of the support member 1 with the string axis and insert the string axis between the two clamping blocks 2. Then rotate the adjustment tube 3 to bring the two clamping blocks 2 closer together, fix the string axis between the two clamping blocks 2, then hold the gripping mechanism and slowly rotate the connecting shaft 4. The torsion spring 6 and the rotating shaft 5 drive the support member 1 to rotate, thereby rotating the string axis and tightening the violin strings. At the same time, the pointer 8 and the angle ruler 7 produce relative rotation, that is, the pointer 8 deflects. Be careful to observe that the deflection angle of the pointer 8 does not exceed the maximum deflection angle of the string to avoid string breakage. The tuner body of the present invention adopts a long-axis structural design that takes up less space. It is suitable for use when the string axis is close together. When tuning, it will not interfere with other string axis, making it more convenient and smooth to use. It can also detect the magnitude of the torque to prevent the string from being over-tightened and breaking.

[0022] By setting up a clamping mechanism, a detection mechanism and a holding mechanism, the clamping mechanism is used to clamp the tuning pegs to prevent them from falling off, and the detection mechanism detects the torque size, which can effectively reduce the possibility of string breakage. The tuner adopts a long-axis structure as a whole, which can avoid interference between the tuner and other tuning pegs during use, making it more convenient to use.

[0023] Example 2: like Figure 1As shown, in this embodiment, there are multiple pointers 8, which are evenly spaced. For example, four pointers 8 bisect the circumference and are of different colors, with the colors gradually darkening as the device is installed clockwise. Alternatively, the four pointers 8 can be individually labeled, using Arabic numerals. When the connecting shaft 4 rotates, at least one pointer 8 is visible in any direction. The color, number, and aligned angle of the pointer 8 clearly indicate the rotation angle of the connecting shaft 4. This measure avoids the disadvantage of insufficient rigidity of the torsion spring 6, which results in excessive deflection of the rotating shaft 4 and invisibility of the pointer 8 from the front. This makes it more convenient to use.

[0024] By providing a plurality of different pointers 8 , the use of the tuner can be facilitated.

[0025] Example 3: like Figure 4-7 As shown, in this embodiment, a mounting groove 9 is opened on the top of the support member 1, the clamping block 2 passes through the side wall of the mounting groove 9 and extends into the mounting groove 9, the clamping block 2 is radially slidably connected to the support member 1, an outer conical surface 10 is provided on the outer side of the clamping block 2, and an inner conical surface 11 is provided in the adjusting tube 3. The adjusting tube 3 is rotated to move axially along the support member 1, and the inner conical surface 11 contacts the outer conical surface 10. As the adjusting tube 3 moves, the clamping block 2 moves toward the center of the mounting groove 9.

[0026] By providing the mounting groove 9 , the outer conical surface 10 and the inner conical surface 11 , the adjusting tube 3 can drive the clamping block 2 to move radially.

[0027] Example 4: like Figure 2 and Figure 6 As shown, a clamping groove 12 is provided on the inner side of the clamping block 2 , and the clamping grooves 12 of the two clamping blocks 2 face each other. When the two clamping blocks 2 are close to each other, the string peg placed between the two clamping grooves 12 can be clamped and fixed.

[0028] By providing a clamping groove 12 on the inner side of the clamping block 2, the tuning peg can be clamped and fixed conveniently.

[0029] Example 5: like Figure 4-6As shown, in this embodiment, an elastic plug plate 13 is installed at the bottom of the clamping block 2, and a connecting plate 14 is fixedly installed on the inner wall of the mounting groove 9. The connecting plate 14 may also have a certain elasticity. A plug hole 15 is provided on the connecting plate 14, and the elastic plug plate 13 passes through the plug hole 15. When in use, when the clamping block 2 moves toward the center of the mounting groove 9, the elastic plug plate 13 contacts and presses the inner side of the plug hole 15. As the clamping block 2 moves further, the elastic plug plate 13 bends and deforms. When the tuning is completed, the adjusting tube 3 moves in the opposite direction. Under the self-stress of the bent elastic plug plate 13, the elastic plug plate 13 straightens, causing the clamping block 2 to move in the opposite direction and reset.

[0030] By providing the elastic inserting plate 13 and the connecting plate 14 , the clamping block 2 can be easily reset, which makes it easier to use the tuner next time.

[0031] Example 6: like Figure 4-5 As shown, in this embodiment, a wear-resistant sheet 16 made of metal is installed on the inner side of the plug hole 15. The wear-resistant sheet 16 contacts the elastic plug plate 13. When the two slide relative to each other, the wear of the contact surface between the elastic plug plate 13 and the connecting plate 14 is reduced through the wear-resistant sheet 16, which is beneficial to improving the service life of the connecting plate 14.

[0032] By installing the wear-resistant sheet 16 on the inner side of the plug hole 15 , the service life of the connecting plate 14 is improved.

[0033] Example 7: like Figure 4-5 As shown, in this embodiment, a plug-in slot 17 is opened at the bottom end of the support member 1, one end of the rotating shaft 5 is inserted into the plug-in slot 17, and a screw 19 is screwed into the threaded hole 18, so that the end of the screw 19 is tightly pressed against the outer wall of the rotating shaft 5, thereby connecting the support member 1 to the rotating shaft 5, and the other end of the rotating shaft 5 is rotatably connected to the connecting shaft 4 through a miniature bearing.

[0034] By providing the insertion groove 17 , the support member 1 can be conveniently connected to the rotating shaft 5 .

[0035] Example 8: like Figure 4-5 As shown, in this embodiment, a spline groove 20 is opened on one side of the plug-in groove 17, and a spline 21 is fixedly installed on the rotating shaft 5. The spline 21 is embedded in the spline groove 20, which can prevent the rotating shaft 4 and the support member 1 from rotating relative to each other and play a limiting role.

[0036] The spline groove 20 and the spline 21 can play a limiting role and prevent the rotating shaft 4 and the support member 1 from rotating relative to each other.

[0037] Example 9: like Figure 8As shown, in this embodiment, the gripping mechanism includes a first handle 22 fixedly connected to the connecting shaft 4. The first handle 22 is U-shaped and has four finger grooves 23 formed therein. When in use, four fingers other than the thumb pass through the middle of the first handle 22 and grip it tightly. The four fingers are caught in the four finger grooves 23 to prevent slipping. Then, the first handle 22 can be rotated to rotate the connecting shaft 4. This structure has a larger diameter and a longer power arm, making it suitable for people with less strength.

[0038] By providing the first handle 22 and opening the finger groove 23 , the connecting shaft 4 can be driven to rotate conveniently.

[0039] Example 10: like Figure 9-10 As shown, in this embodiment, the holding mechanism includes a second handle 24 installed at the bottom end of the connecting shaft 4, and the threaded shaft 25 of the second handle 24 is screwed into the connecting groove at the bottom end of the connecting shaft 4, thereby connecting the second handle 24 to the connecting shaft 4. When in use, holding the second handle 24 can drive the connecting shaft 4 to rotate. The diameter of the pickup of this structure is smaller, but the power arm is smaller, which is suitable for people with greater strength.

[0040] The second handle 24 is installed on one section of the connecting shaft 4, so that the connecting shaft 4 can be driven to rotate conveniently.

[0041] Working principle: When in use, align the end of the support member 1 with the string axis and insert the string axis between the two clamping blocks 2. Then rotate the adjustment tube 3 to bring the two clamping blocks 2 closer to each other and fix the string axis between the two clamping blocks 2. Then hold the holding mechanism and slowly rotate the connecting shaft 4. The torsion spring 6 and the rotating shaft 5 drive the support member 1 to rotate, thereby rotating the string axis and tightening the violin strings. At the same time, the pointer 8 and the angle ruler 7 produce relative rotation, that is, the pointer 8 deflects. Pay attention to observe that the deflection angle of the pointer 8 does not exceed the maximum deflection angle of the string to avoid the string breaking. The tuner body of the present invention adopts a long-axis structural design that takes up less space. It is suitable for use when the string axis is close together. When tuning, it will not interfere with other string axes, making it more convenient and smooth to use. It can also detect the magnitude of the torque to prevent the strings from being over-tightened and breaking.
