[0015] The utility model is further configured such that the external sliding groove of the fixing ring is provided with at least one group.
[0016] By adopting the above technical solution, four are set in this embodiment to facilitate adjustment.
[0017] The utility model is further configured such that both the first contact head and the second contact head are spherical structures.
[0018] By adopting the above technical solution, the resistance rod can resist more smoothly.
[0019] The beneficial effect of the utility model is as follows: compared with the prior art, in the utility model, the pipa can be tuned by rotating the threaded sleeve so that the threaded sleeve does not interfere with the top of the interference rod, and then rotating the string handle to drive the string axis to rotate. When the string axis rotates, the bottom of the interference rod will continuously interfere with the positioning hole; after the adjustment is completed, the threaded sleeve is rotated to allow the threaded sleeve to interfere with the outside of the interference rod, thereby locking the interference rod to be firmly interfered with in the positioning hole, so that the string axis cannot rotate. The pipa can be tuned by rotating the string axis, and then the string axis can be conveniently fixed and rotated by adjusting the threaded sleeve, which is convenient for operation.

[0029] The following is combined with Figure 1-6 The utility model is further described.
[0030] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: a tuning and fixing device for a pipa, comprising a pipa main body 1, in which a plurality of groups of string axes 3 are rotatably connected, a plurality of groups of anti-slip protrusions are fixedly connected to the outside of a threaded sleeve 5, a string handle 2 is fixedly connected to the outside of the string axes 3, the string axes 3 are connected to the strings on the pipa main body 1, and a fixing ring 17 is provided on the outer sleeve of the string axes 3, and the fixing ring 17 is fixedly connected to the pipa main body 1.
[0031] In a further design, a convex ring 4 is fixedly connected to the outside of the fixing ring 17, and a threaded sleeve 5 is also sleeved on the outside of the fixing ring 17. The threaded sleeve 5 is threadedly connected to the convex ring 4. A sliding hole 16 is provided in the fixing ring 17, and a resistance rod 10 is slidably connected in the sliding hole 16. A plurality of positioning holes 13 are provided at the position of the resistance rod 10 corresponding to the outside of the string axis 3. The threaded sleeve 5 is rotated so that the threaded sleeve 5 no longer resists the resistance rod 10, and then the string handle 2 is rotated to drive the string axis 3 to rotate, so that the pipa can be tuned. When the string axis 3 rotates, the resistance rod 10 will continuously resist the positioning hole 13; after the adjustment is completed, the threaded sleeve 5 is rotated so that the threaded sleeve 5 resists the outside of the resistance rod 10, thereby locking the resistance rod 10 firmly in the positioning hole 13, so that the string axis 3 cannot rotate.
[0032] A first contact head 11 and a second contact head 15 are fixedly connected to the top and bottom ends of the contact rod 10 , respectively. Both the first contact head 11 and the second contact head 15 are spherical structures.
[0033] Among them, the annular block 14 is fixedly connected to the resistance rod and the sliding hole 16, and the second spring 12 is sleeved on the outside of the resistance rod. The two ends of the second spring 12 are respectively connected to the two annular blocks 14. Under the action of the second spring 12, when the string axis 3 rotates, the second resistance head 15 will continuously resist the positioning hole 13.
[0034] In a further design, a slide groove 6 is provided on the outside of the fixed ring 17, and at least one group of slide grooves 6 are provided on the outside of the fixed ring 17. A slider 8 is slidably connected in the slide groove 6. An annular slide hole 16 is provided on the outside of the slider 8 and the inner wall of the threaded sleeve 5, and an annular slide bar 9 is slidably connected in the annular slide hole 16. When the threaded sleeve 5 rotates outward, the slider 8 can be driven by the action of the annular slide bar 9 to compress and adjust the spring for buffering.
[0035] In addition, a first spring 7 is connected between the slider 8 and the inner wall of the slide groove 6 .
[0036] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:
[0037] When in use, the threaded sleeve 5 is rotated so that the threaded sleeve 5 no longer contacts the first contact head 11, and then the string handle 2 is rotated to drive the string axis 3 to rotate, so that the pipa can be tuned. When the string axis 3 rotates, the second contact head 15 will continuously contact the positioning hole 13;
[0038] When the threaded sleeve 5 rotates outward, the annular slide bar 9 can drive the slide block 8 to compress and adjust the spring.
[0039] After the adjustment is completed, the threaded sleeve 5 is rotated to make the threaded sleeve 5 contact the outside of the first contact head 11, thereby locking the second contact head 15 firmly in contact with the positioning hole 13, so that the string axis 3 cannot rotate.
[0040] Therefore, in this embodiment, the pipa can be tuned by rotating the peg 3, and then the peg 3 can be conveniently fixed and rotated by adjusting the threaded sleeve 5, which is convenient for operation.
