[0031] Secondly, the "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0032] REFERENCE Figures 1-8 As the first embodiment of the utility model, a tuning wrench is provided, which comprises a tuning wrench main body 10 and an input handle 30.

[0033] The tuning wrench main body 10 comprises a transmission device 11, a positioning rod 12 and a tuning barrel 20.

[0034] The transmission device 11 is a worm gear transmission device.

[0035] The input handle 30 is used to input power for the transmission device 11 to rotate.

[0036] The transmission device 11 is connected with the tuning barrel 20.

[0037] The positioning rod 12 is hingedly connected with the transmission device 11.

[0038] The tuning barrel 20 is sleeved on the string peg of the musical instrument and is used to rotate and adjust the strings of the musical instrument, so as to adjust the intonation of the musical instrument.

[0039] The input handle 30 comprises a handle 31 and a tuning rotating rod 32 fixedly connected with the handle 31.

[0040] Specifically, the input handle 30 is rotated by manpower, the transmission device 11 is driven to rotate, the transmission device 11 is connected with the tuning cylinder 20, the string peg 42 placed in the tuning cylinder 20 is rotated to adjust the pitch of the string 43, and the use requirement is achieved.

[0041] The transmission device 11 comprises a shell 19 and a worm 14 and a worm wheel 15 which are installed in the shell and are in engagement with each other;

[0042] The worm 14 and the worm wheel 15 are respectively provided with a first bearing 18 and a second bearing 16 at two ends;

[0043] One end of the worm wheel 15 is fixedly connected with the tuning cylinder 20;

[0044] The worm 14 is respectively provided with a main transmission hole 13 at two ends.

[0045] Specifically, the tuning rotating rod 32 is inserted into the main transmission hole 13 of the worm 14, the worm 14 is driven to rotate, the worm 14 drives the worm wheel 15 to rotate, and then the rotating force is transmitted to the tuning cylinder 20, and the tuning cylinder 20 is driven to rotate.

[0046] The positioning rod 12 is hinged on the shell 19; the positioning rod 12 is a U-shaped bent rod, and the bottom of the U-shaped bent rod is provided with a through hole 17.

[0047] Specifically, the positioning rod 12 is rotated left and right with the hinged point as the center; the U-shaped bent rod can make the positioning rod 12 cover other string pegs 42, and the reverse force is used to fix the whole transmission device 11, so that the transmission device 11 is not shaken and unstable when the input handle 30 is rotated, and the tuning action is affected. The lengthening rod can be inserted into the through hole 17, so that the length of the positioning rod 12 is increased, and then more labor is saved when the whole transmission device 11 is rotated.

[0050] The tuning cylinder 20 is provided with a tuning hole 21 matched with the string peg.

[0051] Specifically, the rotation of the tuning cylinder 20 can be effectively transmitted to the string peg.

[0052] The use method of the utility model is as follows: Figure 6Taking the guzheng as an example, when opening the tuning box 41 on the main body 40 of the guzheng and plucking the strings to test the sound, determine the string 43 that needs to be tuned, identify the corresponding string pin 42, insert the tuning hole 21 on the tuning tube 20 into the corresponding string pin 42, and rotate it using the positioning rod 12. At this time, the tuning wrench of this utility model is used in the same way as the ordinary tuning wrench.

[0053] Reference Figure 7 In the above Figure 6 Based on the method of use, the positioning rod 12 rotates towards the side of the string pin 42 inside the tuning box 41, locking the other string pins 42 and thus fixing the entire transmission device 11. Then, the tuning lever 32 on the input handle 30 is inserted into the main transmission hole 13 on the worm gear 14. Rotating the input handle 30 transmits the force through the worm gear 14 to the worm wheel 15, further transmitting the rotational force to the tuning cylinder 20, which drives the string pins 42 in the tuning hole 21 to rotate, thus achieving the function of tuning. This method is suitable for adjustments requiring less force and higher precision in pitch, and features stable and reliable adjustment.

[0054] Reference Figure 8 When adjusting the string pin 42 at the end of the tuning box 41, you can follow the instructions. Figure 7 The operating method is as follows: place the positioning rod 12 in reverse and put it on the other string pins 42 above the end string pin 42, and adjust the pitch according to the above method.
