A first chute corresponding to the first support rod 11 is provided on the second support rod 12. The second support rod 12 slides up and down along the first support rod 11 through the first chute. The second support part 2 is located at the top of the second support rod 12 and is connected to the second support rod 12 through a buckle. The second support part 2 includes a first support plate 21 and a second support plate 22. The first support plate 21 is connected to the second support rod 12 through a buckle. The second support plate 22 is slidably connected to the first support plate 21 through a provided adjustment part 4. A second chute corresponding to the second support plate 22 is provided on the top of the first support plate 21. The second support plate 22 moves horizontally on the top of the first support plate 21 along the second chute. The first transmission part 3 includes a first ball screw 31. A cavity is provided inside the first support rod 11. A first opening corresponding to the second support rod 12 is provided at the top of the cavity. The bottom of the second support rod 12 penetrates through the first opening and is slidably connected to the inner wall of the cavity up and down. The first transmission part 3 is located inside the cavity. The first ball screw 31 penetrates through the bottom of the second support rod 12 and is threadedly connected to the second support rod 12. The first ball screw 31 is driven by a motor.

[0027] The adjusting part 4 includes an adjusting component 41 and a support column 42. The support column 42 is located on both sides of one end of the second support plate 22. The second support plate 22 is hinged to the support column 42. The adjusting component 41 is located at one end of the second support plate 22 away from the support column 42. The adjusting component 41 includes a first screw rod 411 and a fixing block 412. The first screw rod 411 passes through the fixing block 412 and is threadedly connected to the fixing block 412. At the top of one end of the first screw rod 411 passing through the fixing block 412, there is a squeezing block 413 connected by rotation. The squeezing block 413 is slidably connected to the first support plate 21. The squeezing block 413 is in contact with one end of the second support plate 22 away from the support column 42; A second opening is provided on the first support plate 21. A limiting part 6 is arranged in the second opening. The limiting part 6 includes a second screw rod 61 and a limiting plate 62. The second screw rod 61 passes through the bottom of the first support plate 21 and is threadedly connected to the first support plate 21. The limiting plate 62 is fixedly connected to the second screw rod 61 inside the second opening.

[0028] A third support part 5 is provided at the bottom of the first support part 1. The third support part 5 includes a support block 51 and a support bottom rod 52. The support block 51 is fixedly connected to the first support rod 11. There are multiple support bottom rods 52 which are circumferentially distributed on the support block 51. One end of the support bottom rod 52 is hinged to the support block 51. A torsion spring corresponding to the support bottom rod 52 is provided on the support block 51.

[0029] During use, it can be selected whether to install the first support part 1 at the bottom of the second support part 2 according to the use scenario. The second support rod 12 is connected to the first support plate 21 through a buckle. When the first support part 1 is installed at the bottom of the first support plate 21, the end of the support bottom rod 52 away from the support block 51 touches the ground to support the first support part 1 and the second support part 2. During the process of the support bottom rod 52 finding the ground, the torsion spring applies a downward force to the support bottom rod 52, so that the end of the support bottom rod 52 away from the support block 51 always keeps in contact with the ground. By driving the first roller screw 31 to rotate through a motor, the first roller screw 31 drives the second support rod 12 to slide up and down along the first support rod 11, thereby adjusting the height position of the second support part 2. Place the music score on the second support plate 22. By rotating the first screw rod 411, the first screw rod 411 drives the squeezing block 413 to slide horizontally on the first support plate 21. During the sliding process of the squeezing block 413, the squeezing block 413 squeezes the second support plate 22, driving the second support plate 22 to rotate around the hinge point with the support column 42, thereby changing the viewing angle of the music score; When there is no need to use the first support part 1 for support, or when it is used in an environment with a relatively small space in the classroom, by disassembling the first support part 1, the second opening on the first support plate 21 is clamped on a fixed plate such as a desktop, and by rotating the second screw rod 61, the limiting plate 62 is driven to move up and down in the second opening to contact the bottom of the desktop for fixation. By using the same method, the first screw rod 411 is rotated to adjust the angle of the second support plate 22.

[0030] Compared with the prior art, driven by the first transmission part 3 and the motor, the second support rod 12 can slide up and down along the first support rod 11, so as to easily adjust the height of the second support part 2, meet the needs of users of different heights, improve the versatility and comfort. Through the adjusting part 4, the second support plate 22 can be angularly flipped around the support column 42, allowing the user to adjust the viewing angle of the music score according to actual needs, improving the convenience and efficiency of teaching. The first support part 1 and the second support part 2 are combined by snap connection, and at the same time, the third support part 5 is designed, so that the device can be quickly installed and stably supported when needed, and can also be easily disassembled when not needed, which is convenient for carrying and storage. Through the design of the support bottom rod 52 and the torsion spring, even if the ground is uneven, the contact between the support bottom rod 52 and the ground can be maintained, improving the durability and reliability of the device. Through the limiting part 6, the second support part 2 can be fixed on a fixed plate such as a desktop, greatly expanding the use scenarios of the device, especially more advantageous in environments with limited space such as classrooms.

[0031] Embodiment 2: In the above embodiment, when supporting, it often directly contacts the ground or the desktop, and it is easy to cause the device to shake or slip due to uneven contact surfaces or insufficient friction, and only relies on gravity to fix the music score, and it is easy for the music score to slide or shift due to wind, vibration or human touch. Therefore, in this application embodiment, the second support part 2, the third support part 5 and the limiting part 6 are optimized on the basis of the above embodiment.

[0032] In this embodiment, a first rubber ball 63 is provided on the limiting plate 62. The first rubber balls 63 are multiple and linearly distributed on the upper surface of the limiting plate 62. A groove corresponding to the music score is provided on the second support plate 22, and the music score is placed in the groove. An extrusion assembly 221 is provided on the second support plate 22. The extrusion assembly 221 is located at the bottom of the groove near one end of the adjusting assembly 41. The extrusion assembly 221 includes a support frame body 2211 and an air bag 2212. The air bag 2212 is located at the top of the support frame body 2211 corresponding to the groove, and the support frame body 2211 is fixedly connected to the second support plate 22; A second rubber ball 521 is provided at the bottom of one end of the support bottom rod 52 away from the support block 51, and the second rubber ball 521 is fixedly connected to the support bottom rod 52.

[0033] During use, by setting the second rubber ball 521 at the bottom of the support bottom rod 52, it can ensure that the force is concentrated during the contact between the support bottom rod 52 and the ground, and the second rubber ball 521 can prevent the support bottom rod 52 from slipping when fixed. By setting a plurality of first rubber balls 63 on the limit plate 62, the plurality of first rubber balls 63 can be deformed under the extrusion of the limit plate 62, making the contact with the fixed tabletop closer, ensuring the stability of the contact between the first support plate 21 and the tabletop. After placing the music score, the airbag 2212 is inflated to squeeze the music score to ensure that the music score can be fixed in the groove.

[0034] Compared with the prior art, by setting the second rubber ball 521 at the bottom of the support bottom rod 52, it can disperse the pressure during support, adapt to the uneven ground, and provide additional friction, effectively preventing the support bottom rod 52 from slipping when fixed, significantly enhancing the support stability of the device, making the device more stable during use. By setting a plurality of first rubber balls 63 on the limit plate 62, the first rubber balls 63 can be deformed when being extruded by the limit plate 62, forming a closer contact with the fixed tabletop, increasing the contact area and friction, making the fixation between the first support plate 21 and the tabletop more firm and not easy to loosen even under external forces. By setting the extrusion assembly 221 on the second support plate 22, the airbag 2212 is inflated to squeeze the music score, enabling the music score to be tightly fixed in the groove. The airbag 2212 provides a uniform clamping force, adapting to the thickness and shape of the music score, ensuring the stability of the music score during performance or teaching, and not easy to slip or shift even under wind or vibration.

[0035] Embodiment 3: In the above embodiment, the volume of the third support part 5 is relatively large when it needs to be stored, and it is inconvenient to adjust the volume of the third support part 5, and the center of gravity is unstable on the inclined ground. Therefore, in this application embodiment, the third support part 5 is optimized on the basis of the above embodiment.

[0036] In this embodiment, the third support part 5 is connected to the first support rod 11 through a stud 13. A screw sleeve 14 is provided on the stud 13, and the screw sleeve 14 is threadedly connected to the stud 13. The third support part 5 is located below the screw sleeve 14. The inner diameter of the screw sleeve 14 is larger than the outer diameter of the support block 51. A handle 141 is provided on the screw sleeve 14, and the handle 141 is fixedly connected to the screw sleeve 14. A suction cup 142 fixedly connected is provided at the bottom of the screw sleeve 14, and the suction cup 142 is located below the support block 51.

[0037] When storage is required during use, the handle 141 is rotated downward to turn the screw sleeve 14, and the screw sleeve 14 gathers the support bottom rod 52 towards the middle, reducing the volume of the third support portion 5. During the process of use, the screw sleeve 14 is rotated upward, the screw sleeve 14 is separated from the support bottom rod 52, and the support bottom rod 52 provides support. At the same time, the suction cup 142 at the bottom of the screw sleeve 14 touches the ground for adsorption to ensure that the center of gravity of the third support portion 5 does not move.

[0038] Compared with the prior art, through the stud 13, the screw sleeve 14 and the handle 141, the up and down movement of the screw sleeve 14 can be realized by simply rotating the handle 141. When storage is required, the handle 141 is rotated downward, and the screw sleeve 14 gathers the support bottom rod 52 towards the middle, effectively reducing the volume of the third support portion 5 and making storage more convenient and fast. A suction cup 142 is provided at the bottom of the screw sleeve 14. When the screw sleeve 14 is rotated upward and separated from the support bottom rod 52, and the third support portion 5 is unfolded for support, the suction cup 142 can touch the ground for adsorption, effectively fixing the position of the third support portion 5 and ensuring that its center of gravity does not move, and it can remain stable even on an inclined ground.

[0039] The present invention and its embodiments have been described above. Such description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
