[0002] Guitar is one of the most popular instruments in the world, widely used in various musical styles, such as pop, rock, and folk music. Learning guitar not only improves musical skills but also increases enjoyment and relaxation. Guitar comes in many forms, including classical guitar, electric guitar, and folk guitar.

[0003] When playing guitar, it's important to place the guitar in a comfortable position to allow for free and focused playing, while maintaining correct arm and wrist posture to prevent muscle fatigue and injury, and to enhance performance. Most guitarists prefer to sit while playing, choosing a chair or stool and placing the guitar on their right or left leg, ensuring the base of the guitar rests firmly against their thigh for comfortable playing. However, existing guitar bases can easily slip off the legs, affecting performance and causing frustration for guitarists. Summary of the Invention

[0031] The lower bracket 1 is fixed to the middle part of the piano body 4, and the lower bracket 1 is supported by the legs;

[0032] The upper bracket 2 is rotatably connected to the piano body 4. A first through hole 5 is formed at the top of the upper bracket 2, and a second through hole 6 is formed at the bottom of the upper bracket 2.

[0033] The rotating shaft 3 is fixedly connected to the piano body 4 . The rotating shaft 3 includes a rotating shaft core 301 and a damping rotating shaft 302 . The rotating shaft core 301 passes through the first through hole 5 , and the damping rotating shaft 302 passes through the second through hole 6 .

[0034] In one embodiment, Figure 1-4 As shown, the lower bracket 1 is fixed to the middle of the side edge of the guitar body 4, and the upper bracket 2 is located on one side of the lower bracket 1. The lower bracket 1 is close to the edge of the guitar body 4, leaving space for the upper bracket 2. The shaft core 301 is set at the position where the guitar body 4 and the neck 7 are connected, and the damping shaft 302 is set at the bottom of the guitar body 4. When playing, the lower bracket 1 supports the legs to prevent the guitar from slipping from the legs. The upper bracket 2 rotates 180 degrees around the shaft core 301 and the damping shaft 302 in the direction away from the lower bracket 1 to be in an open state. After opening, the upper bracket 2 is used to support the arm to provide a comfortable playing posture for the user. When the performance is finished, the upper bracket 2 is rotated in the opposite direction and returns to the initial position, which reduces the occupied space and is convenient for carrying and storage.

[0035] The lower bracket 1 is arc-shaped, and the root of the lower bracket 1 extends tangentially from the piano body 4.

[0036] In one embodiment, Figure 2 As shown, the curvature of the lower bracket 1 is as close as possible to the curvature of the human leg, so that the guitar can be stably placed on the leg and the contact area with the leg is increased. The root of the lower bracket 1 is fixed inside the guitar body 4, and the surface of the guitar body 4 is opened so that the lower bracket 1 extends out of the guitar body 4.

[0037] The upper bracket 2 includes a curved portion 201 and a straight rod portion 202 . The straight rod portion 202 is fixed to the top end of the curved portion 201 . The shape of the curved portion 201 is similar to the outer shape of the piano body 4 .

[0038] In one embodiment, Figure 3 and Figure 4 As shown, the bending radius of the lower side of the curved surface portion 201 is smaller than the bending radius of the upper side of the curved surface portion 201, the upper and lower sides of the curved surface portion 201 are smoothly connected, and the lower side of the curved surface portion 201 is used to support the arm when the lower bracket 1 is opened. The shape of the curved surface portion 201 is similar to the edge shape of the left side of the piano body 4, ensuring that the upper bracket 2 is completely received in the piano body 4, and the straight rod portion 202 is T-shaped. The first through hole 5 is opened at the end of the straight rod portion 202 away from the curved surface portion 201, and the second through hole 6 is opened at the end of the curved surface portion 201.

[0039] The damping shaft 302 includes a thin-diameter shaft 3021, a thick-diameter shaft 3022, and a threaded hole 3023. The thin-diameter shaft 3021 is fixedly connected to the thick-diameter shaft 3022. One end of the thick-diameter shaft 3022 is provided with symmetrical notches 3024. The threaded hole 3023 is arranged between the notches 3024. The notches 3024 form a protrusion 3025 at one end of the thick-diameter shaft 3022.

[0040] In one embodiment, Figure 6 As shown, the thin-diameter shaft 3021 and the thick-diameter shaft 3022 are both cylindrical, and the thin-diameter shaft 3021 and the thick-diameter shaft 3022 are integrally formed and coaxially connected, and the notch 3024 is provided at one end away from the thin-diameter shaft 3021 .

[0041] A threaded nail 8 is connected in the threaded hole 3023 .

[0042] In one embodiment, Figure 7 As shown, the screw 8 is a strap nail for fixing the guitar strap, the threaded hole 3023 is threadedly connected to the screw 8, and a part of the screw 8 is screwed into the threaded hole 3023. The use of the screw 8 facilitates the detachable connection between the strap and the guitar.

[0043] The second through hole 6 includes a circular hole 601 and a straight slot hole 602 , and the circular hole 601 and the straight slot hole 602 are connected.

[0044] In one embodiment, Figure 1 、 Figure 4 、 Figure 5 、 Figure 6As shown, the straight slot hole 602 is provided inside the circular hole 601 , the screw 8 is sleeved in the circular hole 601 , and the protrusion 3025 formed by the damping shaft 302 is sleeved in the straight slot hole 602 .

[0045] A fixing frame 9 and a retaining ring 10 are provided on the thin-diameter shaft 3021. The retaining ring 10 is arranged on the inner side of the fixing frame 9. The fixing frame 9 includes multiple legs 901, a fixing plate 902, a third through hole 903 and a fourth through hole 904. The multiple legs 901 are all connected to the fixing plate 902. The third through hole 903 is arranged on the fixing plate 902. The fourth through hole 904 is arranged on the legs 901.

[0046] In one embodiment, Figure 6 、 Figure 7 and Figure 8 As shown, the support leg 901 is fixedly connected to the inside of the piano body 4, and the support leg 901 is vertically connected to the fixing plate 902. There are two support legs 901, and the two support legs 901 are connected to both sides of the fixing plate 902. There are multiple third through holes 903, and the bolts are screwed into the third through holes 903 to realize the connection between the fixing frame 9 and the piano body 4. The fourth through hole 904 is set between the two support legs 901, and the thin diameter shaft 3021 passes through the fourth through hole 904 and the retaining ring 10 in sequence. The distance between the retaining ring 10 and the thick diameter shaft 3022 is equal to the thickness of the fixing plate 902. The retaining ring 10 prevents the damping shaft 302 from falling off and loosening. When the upper bracket 2 is rotated, the thin diameter shaft 3021 rotates in the fourth through hole 904, and the thick diameter shaft 3022 and the threaded nail 8 rotate synchronously.

[0047] A groove 11 is formed on the top of the piano body 4 , and the shaft core 301 is disposed in the groove 11 .

[0048] In one embodiment, Figure 2 As shown, the groove 11 is a through groove, and the shaft core 301 is mounted in the groove 11. When the upper bracket 2 is opened or closed, the straight rod portion 202 fits against the inner wall of the groove 11, and the groove 11 prevents the upper bracket 2 from excessive rotation.

[0049] The above describes preferred embodiments of the present invention. However, the above description is not intended to be limiting. Those skilled in the art may make numerous changes or modifications to the present invention without departing from the spirit and scope of the present invention. Such changes or modifications are intended to fall within the scope of the appended claims.
