[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a tightening tool for repairing strings, comprising: a piano body 1 and an outer frame 2; a tightening assembly 3, the tightening assembly 3 is fixedly connected to the top of the outer frame 2, the tightening assembly 3 comprises a side frame 301, the outer surface of the side frame 301 is threadedly connected with a hand screw bolt 302, the end surface of the hand screw bolt 302 is rotatably connected with a moving plate 304, the top of the moving plate 304 is provided with a plurality of adjustment grooves 305, the inner surface of the adjustment groove 305 is provided with a threaded rod 307, the outer surface of the threaded rod 307 is threadedly connected with a threaded sleeve 308, the lower end surface of the threaded sleeve 308 is rotatably connected with a rotating seat 309, and the bottom of the rotating seat 309 is provided with a plurality of adjustment grooves 305. The outer surface of the outer frame 2 is fixedly connected with a support block 310, and the outer surface of the threaded sleeve 308 is fixedly connected with an anti-slip sleeve 311. The top of the outer frame 2 is fixedly connected with a top plate 4, and the bottom of the top plate 4 is fixedly connected with a slide rail 5. The top of the threaded rod 307 is fixedly connected with a slider 306, and the inner surface of the slider 306 is slidably connected to the inner surface of the slide rail 5. The outer surface of the movable plate 304 is symmetrically fixedly connected with a limit rod 303, and the limit rod 303 slides through and extends to the outside with the side frame 301. The inner surfaces of both sides of the outer frame 2 are symmetrically fixedly connected with springs 6, and the end surfaces of the two groups of springs 6 are fixedly connected with a splint 7, and the piano body 1 is located between the two splints 7.

[0023] The effect achieved by the entire embodiment 1 is that when the strings of the guqin are repaired, the outer frame 2 is placed at the outer side of the guqin body 1, and the rebound force of the springs 6 on both sides is used to clamp and fix the guqin body 1 between the two clamping plates 7, so that the outer frame 2 and the guqin body 1 maintain a relatively stable position to repair the strings. When the strings are tightened during maintenance, the spacing of the multiple support blocks 310 can be adjusted according to the spacing of the strings of the guqin. When the spacing of the strings is small, the hand-tightening bolt 302 can be turned to drive the movable plate 304 to move to the left. The movable plate 304 can play a limiting role through the limiting rod 303 when moving. When the movable plate 304 moves to the left, it can drive the threaded rod 307 along the adjustment groove 3 05, and the threaded rod 307 moves along the slide rail 5 through the slider 306 when moving, so that the movement trajectory of the threaded rod 307 is limited to forward and backward movement. Therefore, when the threaded rod 307 moves along the path change of the adjustment groove 305, the spacing between the multiple threaded rods 307 can be reduced. At this time, the spacing between the multiple support blocks 310 at the bottom changes. After the spacing between the support blocks 310 is adjusted, the multiple support blocks 310 can be respectively aligned with the strings at the bottom for tightening. When tightening the strings for maintenance, the anti-slip sleeve 311 is rotated to drive the threaded sleeve 308 to rotate. The rotation of the threaded sleeve 308 can drive the support block 310 to move downward to apply pressure to the strings, thereby achieving the purpose of tightening the strings.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the outer surface of the clamping plate 7 away from the piano body 1 is symmetrically fixedly connected with a pull rod 8, the pull rod 8 slides through the outer frame 2 and extends to the outside, and a pull plate 9 is fixedly connected between the end surfaces of the two pull rods 8.

[0025] The effect achieved by the entire embodiment 2 is that after the guqin is repaired, the pull plates 9 on both sides are pulled outwards, and the guqin body 1 can be directly taken out to avoid directly pulling out the guqin body 1 and causing the guqin body 1 to be scratched by the splint 7, so that the tightening tool can better protect the guqin when in use.

[0026] Working principle: When repairing the strings of the guqin, the outer frame 2 is placed on the outer side of the body 1, and the body 1 is clamped and fixed between the two clamping plates 7 by utilizing the resilience of the springs 6 on both sides, so that the outer frame 2 and the body 1 maintain a relatively stable position for repairing the strings. When the strings are tightened during repair, the spacing of multiple support blocks 310 can be adjusted according to the spacing of the strings of the guqin. When the spacing of the strings is small, the hand-tightening bolt 302 can be turned to drive the movable plate 304 to move to the left. The movable plate 304 can play a limiting role through the limiting rod 303 when moving. When the movable plate 304 moves to the left, it can drive the threaded rod 307 to move along the path of the adjusting groove 305, and the threaded rod 307 will move along the slide rail 5 through the slider 306 when moving, so that the movement trajectory of the threaded rod 307 is limited to forward and backward movement. Therefore, when the threaded rod 307 moves along the path change of the adjusting groove 305, multiple threaded rods can be moved. When the distance between the rods 307 becomes smaller, the distance between the multiple support blocks 310 at the bottom changes. After the distance between the support blocks 310 is adjusted, the multiple support blocks 310 can be respectively aligned with the bottom strings for tightening. When tightening the strings for maintenance, the anti-slip sleeve 311 is rotated to drive the threaded sleeve 308 to rotate. The rotation of the threaded sleeve 308 can drive the support block 310 to move down to apply pressure to the strings, thereby achieving the purpose of tightening the strings. The spacing adjustment setting can be performed when the multiple support blocks 310 are used. The tightening tool can be adapted to guqins with various string spacings to achieve rapid adjustment for tightening maintenance, thereby improving the convenience of using the string tightening tool. After the maintenance of the guqin is completed, the pull plates 9 on both sides are pulled outward, and the pull plates 9 can drive the clamping plates 7 to move away and loosen the clamping of the guqin body 1. At this time, the guqin body 1 can be directly taken out, avoiding directly pulling out the guqin body 1 and causing the guqin body 1 to be scratched by the clamping plates 7, so that the tightening tool has a better protective effect on the guqin when in use.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
