[0006] Preferably, both upper and lower sides of the threaded rod are provided with avoidance grooves for avoiding the strings.

[0007] Preferably, a plurality of positioning grooves are formed at one end of the plurality of threaded barrels, and the plurality of positioning grooves are symmetrically distributed.

[0008] Preferably, a hexagonal block is welded at one end of each of the threaded barrels.

[0009] Preferably, a plurality of indicator marks are bonded to the top inner wall of the installation groove, and the indicator marks correspond to the placement grooves.

[0010] Preferably, a protective cover is rotatably connected to the top outer wall of the kite body.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: through the arrangement of the threaded rod, the slot and the threaded barrel, one end of the string is wound around the circumferential outer wall of the positioning block, and the other end of the string is passed through the zither body, bypassed from the top of the zither body, and again inserted into the slot opened on the threaded rod on one side of the fixed plate inside the zither body, and fixed with a threaded barrel, so that the replacement of the string can be completed without special winding techniques, thereby improving the efficiency of string replacement.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 5The utility model provides a fast string-changing guzheng device, comprising a guzheng body 1, a plurality of strings 2 are arranged on the top of the guzheng body 1, a fixing plate 5 is riveted between the inner walls on both sides of the guzheng body 1, a threaded rod 9 with the same number as the strings 2 is detachably connected to one side of the fixing plate 5 by bolts, a clamping groove 10 is provided at one end of the threaded rod 9, and one end of the strings 2 is clamped in the clamping groove 10, a threaded tube 6 is threadedly connected to the circumferential outer wall of the threaded rod 9, a mounting groove 4 is provided at the bottom of the guzheng body 1, a plurality of placement grooves 14 are provided on the top inner wall of the mounting groove 4, a positioning block 12 is clamped in the placement groove 14, and one end of the strings 2 is wound around the circumferential outer wall of the positioning block 12 When the strings 2 need to be replaced, the threaded tube 6 is rotated to make the threaded tube 6 disengage from the strings 2, so that the strings 2 can be drawn out of the slot 10, and then the positioning block 12 is taken out from the placement slot 14, so that the strings 2 are disassembled. When installing, one end of the string 2 is wound around the circumferential outer wall of the positioning block 12, and the other end of the string 2 passes through the zither body 1, bypasses from the top of the zither body 1, and is inserted into the slot 10 opened on the threaded rod 9 on one side of the fixing plate 5 in the zither body 1 again, and is fixed with the threaded tube 6. The replacement of the strings 2 can be completed without special winding techniques, thereby improving the replacement efficiency of the strings 2.

[0020] In this embodiment, both upper and lower sides of the threaded rod 9 are provided with avoidance grooves 8 for avoiding the strings 2. When the threaded tube 6 is rotated, the threaded tube 6 will squeeze the strings 2 so that the strings 2 are stuck in the avoidance grooves 8, thereby completing the tensioning of the strings 2. One end of the multiple threaded tubes 6 is provided with multiple positioning grooves 11, and the multiple positioning grooves 11 are symmetrically distributed. After the strings 2 are tensioned, the strings 2 will be stuck in the positioning grooves 11 to assist in fixing the threaded tube 6. One end of the multiple threaded tubes 6 is welded with a hexagonal block 7, which can be used to drive the threaded tube 6 to rotate with the help of a tool, making the rotation of the threaded tube 6 easier. The top inner wall of the installation groove 4 is bonded with multiple indicator marks 13, and the indicator mark 13 corresponds to the placement groove 14. When disassembling, the disassembled string 2 can be found more quickly, further improving the replacement efficiency of the strings 2. The top outer wall of the zither body 1 is rotatably connected with a protective cover 3 to protect the adjustment part.

[0021] The working principle and use process of the utility model are as follows: during installation, one end of the string 2 is wound around the circumferential outer wall of the positioning block 12, and the other end of the string 2 is passed through the zither body 1, bypassed from the top of the zither body 1, and inserted again into the clamping groove 10 opened on the threaded rod 9 on one side of the fixing plate 5 in the zither body 1, and fixed with a threaded tube 6. The threaded tube 6 is driven to rotate with the help of a tool, and the threaded tube 6 will squeeze the string 2, so that the string 2 is clamped into the avoidance groove 8, thereby completing the tensioning of the string 2. After the tensioning of the string 2 is completed, the string 2 is clamped into the positioning groove 11 to assist in fixing the threaded tube 6.

[0022] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
