[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-5, the present utility model provides a technical solution: a connection structure between a yoke iron and a moving reed, including a connection structure main body 1, a yoke iron 7, and a moving reed 8. The connection structure main body 1 is arranged on the yoke iron 7 and the moving reed 8. The yoke iron 7 is of an L-shaped structure, and an integrally formed L-shaped positioning member 2 and a riveting seat 4 are provided on the outer side of the side surface of the yoke iron 7. The yoke iron 7 and the moving reed 8 can be riveted and fixed through the riveting seat 4. A first limiting hole 10 is opened in the middle of the side surface of the moving reed 8, and the position of the first limiting hole 10 corresponds to that of the positioning member 2. This structure enables the moving reed 8 to be clamped relative to the positioning member 2 through the first limiting hole 10, realizing the butt joint positioning process when the moving reed 8 is connected to the moving reed 8. A tightly fixed positioning spring 3 is fixed inside the side surface of the positioning member 2, and the other end of the tightly fixed positioning spring 3 is provided with a fastener 9 with an inclined surface on the side surface, so that the tightly fixed positioning spring 3 connects the fastener 9 and the positioning member 2, and enables the fastener 9 to move relative to the positioning member 2. The side dimension of the L-shaped structure of the positioning member 2 is smaller than the dimension of the first limiting hole 10, and the side surface of the L-shaped structure of the positioning member 2 inclines towards the yoke iron 7, and the distance between the upper end of the positioning member 2 and the yoke iron 7 is greater than the thickness of the moving reed 8. This structure makes the positioning member 2 have a certain included angle through the inclination of the side surface of the positioning member 2, making it easier for the first limiting hole 10 to be clamped with the positioning member 2. At the same time, when the moving reed 8 is pushed, the moving reed 8 can push the fastener 9 to the side through the inclined surface of the fastener 9, so that the fastener 9 compresses the tightly fixed positioning spring 3. Until the moving reed 8 is pushed in place, the fastener 9 is tightly attached to the moving reed 8 through the rebound of the tightly fixed positioning spring 3, making the moving reed 8 and the yoke iron 7 firm. Second limiting holes 11 with a waist-shaped hole structure are symmetrically opened on the side surface of the moving reed 8, and the position of the second limiting holes 11 corresponds to that of the riveting seat 4. This structure enables the moving reed 8 to be clamped relative to the riveting seat 4 through the second limiting holes 11, realizing the positioning of the moving reed 8 and the yoke iron 7 and ensuring the accuracy of the positioning. The second limiting holes 11 are vertically opened, and the second limiting holes 11 and the first limiting holes 10 are distributed in a triangular structure. This structure enables the yoke iron 7 and the moving reed 8 to move relative to each other in the vertical direction through the vertical opening of the second limiting holes 11. After the moving reed 8 is butt-joint positioned relative to the yoke iron 7, the moving reed 8 can be pushed to realize the positioning and fastening of the moving reed 8 and the yoke iron 7, providing stable positioning for the subsequent fixation between the moving reed 8 and the yoke iron 7. Clamping convex plates 5 formed by bending are sleeved on both sides of the lower end of the moving reed 8, and a groove structure is arranged at the lower end of the clamping convex plates 5. Grooves are respectively opened at both ends of the side surface of the yoke iron 7, and clamping seats 6 with an integrally formed structure are arranged at the groove positions on both sides of the yoke iron 7, and the clamping seats 6 are tightly clamped with the grooves at the lower end of the clamping convex plates 5. The part of the moving reed 8 where the clamping convex plates 5 are arranged forms a U-shaped structure, and the moving reed 8 is movably clamped with the yoke iron 7 through the clamping convex plates 5, and the thickness of the moving reed 8 is smaller than the width of the clamping seat 6. This structure enables the moving reed 8 to be positioned through the clamping of the clamping convex plates 5 and the yoke iron 7, ensuring that the clamping convex plates 5 and the clamping seats 6 are clamped with each other at the same time.Avoid the separation between the moving reed 8 and the yoke 7, reduce the looseness during use. A clamping groove 12 is provided at the upper end of the yoke 7, and the width of the clamping groove 12 is greater than the width of the moving reed 8 at the adjacent part.

[0020] Working principle: When using the connection structure of the yoke and the moving reed, first make the first limiting hole 10 and the second limiting hole 11 of the moving reed 8 correspond to the positioning member 2 and the riveting seat 4 respectively. At the same time, the moving reed 8 is clamped to the yoke 7 through the clamping convex plate 5. At this time, the positioning member 2 and the riveting seat 4 are respectively clamped into the first limiting hole 10 and the second limiting hole 11. Then push the moving reed 8 relative to the yoke 7, so that the clamping convex plate 5 passes through the groove part to hold the clamping seat 6. At the same time, the moving reed 8 moves relative to the riveting seat 4 through the second limiting hole 11, and the moving reed 8 is clamped into the fastener 9 from the inclined surface of the fastener 9 through the first limiting hole 10, and the fastening positioning spring 3 is compressed to realize the relative stable positioning between the moving reed 8 and the yoke 7. After that, the moving reed 8 and the yoke 7 are connected and fixed at the riveting seat 4 of the connection structure main body 1. The clamping groove 12 provides a moving space for the moving reed 8, thus completing a series of operations.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
