[0002] The guitar is a very common stringed instrument. Nowadays, people who use guitars have higher and higher requirements for the sound quality of guitars. Since the strings are used for a long time, the string sounds may become inaccurate. At this time, it is necessary to tighten the strings or replace the strings to ensure the standard of the string sounds. Therefore, adjustment equipment is needed to adjust the strings.
[0003] When the traditional adjustment equipment is in use, it can simultaneously rotate the string winder, remove the string fixing nails, and cut the strings. However, when the traditional equipment rotates the string winder, due to the relatively smooth outer wall of the string winder, when the traditional adjustment equipment is sleeved on the outer wall of the string winder, there is a lack of fixation for the string winder, resulting in the adjustment equipment falling off the outer wall of the string winder during rotation, thus causing scratches on the string winder or even on the guitar.

[0025] In a preferred embodiment: anti-slip sleeves are installed on the outer walls of both the first cutting pliers 1 and the second cutting pliers 2, and the anti-slip sleeves are all made of natural rubber.
[0026] By installing the rubber anti-slip cover on the outer walls of the No. 1 cutting pliers 1 and the No. 2 cutting pliers 2, when using the No. 1 cutting pliers 1 and the No. 2 cutting pliers 2 to cut the strings, it is only necessary to put the strings between the outer walls of the No. 1 cutting pliers 1 and the No. 2 cutting pliers 2, and then the strings can be cut under the action of the No. 1 cutting pliers 1 and the No. 2 cutting pliers 2. During the cutting process, the anti-slip cover can increase the friction between the hands.
[0027] In a preferred embodiment, a limiting groove is provided in the inner cavity of the fixing cylinder 6 , and the shape and size of the inner wall of the limiting groove matches the shape and size of the outer wall of the limiting ring 8 .
[0028] By opening a limit groove in the inner cavity of the fixed tube 6, the limit ring 8 is fixed under the action of the limit groove, so that the rotating rod 7 can only rotate in the inner cavity of the fixed tube 6 and cannot be separated from the inner cavity of the fixed tube 6, thereby adjusting the strings under the action of the rotating rod 7 and the adjusting sleeve 12.
[0029] In a preferred embodiment, the control board 11 is electrically connected to the trigger board 10 and the display screen 3 , and the outer wall of the trigger rod 9 is in contact with the outer wall of the trigger board 10 .
[0030] By means of the trigger plate 10 provided on the outer wall of the fixed tube 6, when the rotating rod 7 rotates, the rotating rod 7 rotates one circle, and the trigger rod 9 on the outer wall of the rotating rod 7 will trigger the trigger plate 10 once, which is recorded on the control board 11 and fed back to the display screen 3. At this time, the number of circles of rotation of the rotating rod 7 can be clearly observed on the outer wall of the display screen 3, so that the number of circles of rotation of the guitar winder driven by the adjustment sleeve 12 can be more clearly known.
[0031] In a preferred embodiment, two ends of the outer wall of the driving spring 15 are in contact with the outer wall of the limiting plate 13 and the inner wall of the adjusting sleeve 12 respectively, and the driving spring 15 is made of high carbon steel.
[0032] By means of a driving spring 15 sleeved on the outer wall of the pull rod 14, the limit plate 13 can be pushed to move under the action of the driving spring 15, so that the outer wall of the limit plate 13 can fit on the outer wall of the string winder, thereby better fixing the string winder to the inner cavity of the adjustment sleeve 12 under the action of the limit plate 13.
[0033] In a preferred embodiment, there are two limit plates 13 , and the two limit plates 13 are respectively installed on two sides of the inner cavity of the adjustment sleeve 12 .
[0034] By providing limiting plates 13 on both sides inside the cavity of the adjusting sleeve 12, when using the adjusting sleeve 12 to sleeved and rotate the winder, only need to pull the pull rod 14, sleeve the adjusting sleeve 12 on the outer wall of the winder, and then release the pull rod 14. At this time, the outer wall of the limiting plate 13 can be closely attached to the outer wall of the winder. Then, rotate the rotating rod 7, and under the action of the adjusting sleeve 12 and the rotating rod 7, it is more convenient to drive the rotation of the winder.
[0035] In a preferred embodiment: an anti-slip pad is installed on the outer wall of the limiting plate 13, and the anti-slip pad is made of natural rubber.
[0036] By the anti-slip pad installed on the outer wall of the limiting plate 13, when the outer wall of the anti-slip pad contacts the outer wall of the winder, the friction between the limiting plate 13 and the outer wall of the winder can be increased, so as to better realize the rotation of the winder under the action of the adjusting sleeve 12.
[0037] In a preferred embodiment: both the first cutting pliers 1 and the second cutting pliers 2 are made of high carbon steel. A button battery is installed on the outer wall of the second cutting pliers 2, and the button battery is electrically connected to the display screen 3, the control board 11, and the trigger board 10 respectively.
[0038] By the button battery installed on the outer wall of the second cutting pliers 2, the display screen 3, the control board 11, and the trigger board 10 are powered under the action of the button battery. So that when the rotating rod 7 rotates one circle, the trigger board 10 can be triggered once under the action of the trigger rod 9, and is recorded by the control board 11 and fed back to the outer wall of the display screen 3 for display.
[0039] Working principle: During the use of the above equipment, when it is necessary to cut the string with the equipment, open the first cutting pliers 1 and the second cutting pliers 2, and then place the string between the outer walls of the first cutting pliers 1 and the second cutting pliers 2. At this time, the first cutting pliers 1 and the second cutting pliers 2 can be used to cut the string. When it is necessary to remove the string fixing nail, align the nail extractor 4 with the position of the nail, and snap the nail removal groove 5 onto the outer wall of the nail. At this time, the nail can be removed under the action of the nail extractor 4 and the nail removal groove 5. When it is necessary to use the adjusting sleeve 12 to rotate the winder, pull the pull rod 14, and at the same time sleeve the adjusting sleeve 12 on the outer wall of the winder. Then, rotate the rotating rod 7 and the adjusting sleeve 12. Under the action of the rotating rod 7 and the adjusting sleeve 12, drive the rotation of the winder to adjust the string. During the rotation of the rotating rod 7, the trigger rod 9 on the outer wall of the rotating rod 7 will contact the trigger board 10. After the rotating rod 7 rotates one circle, the trigger rod 9 will trigger the trigger board 10 once, and is recorded by the control board 11 and then fed back to the outer wall of the display screen 3. In this way, during the use, it is possible to clearly know the number of turns of the rotation of the adjusting sleeve 12, and better adjust the winder of the string.
