The mounting base 25 is fixed to the upper end of the telescopic rod 13, and the mounting block 24 is slidably embedded in the mounting base 25. The two are connected by the locking bolt 23 threadedly. By loosening the bolt, the position of the mounting block 24 in the mounting base 25 can be finely adjusted, thereby adjusting the horizontal angle of the base plate 4 to ensure that the placement plate 6 faces the user. The base plate 4 is fixedly installed at the upper end of the mounting block 24, and rectangular blocks 5 are fixedly installed on both sides of the upper end of the base plate 4. The placement plate 6 for placing music scores is rotatably installed between the rectangular blocks 5. The placement plate 6 is the core functional component for placing music scores. The upper bottom is provided with a positioning strip 11 (to assist in music score alignment), and the sides are provided with grooves 9 (for installation limits). The bottom of the placement plate 6 (with limit screw 10 and slide bar 27) is connected to the base plate 4 via a hinge structure, allowing for adjustable tilt angles. After use, it can be folded to fit snugly against the base plate 4. A positioning strip 11 is fixedly installed at the bottom of the upper end of the placement plate 6. Slide grooves 9 are provided on both sides of the placement plate 6, with limit screw 10 and slide bar 27 respectively installed in the slide grooves 9. Slider 16 is slidably installed on both the limit screw 10 and slide bar 27. The limit screw 10 and slide bar 27 are threadedly connected to the slide bar 16. An anti-fall limit is fixedly installed on the upper end of the slide bar 16. The base plate 4 is also equipped with LED lights 8 and lampshades 7 for lighting; the placement plate 6 is connected to the base plate 4 through a hinge structure to achieve angle adjustment; the telescopic rod 13 is locked and fixed to the support cylinder 2 through the locking valve 14; a counterweight 26 is provided in the base 1; the locking valve 14 is a knob-type component that penetrates the side wall of the support cylinder 2; when tightened, the end abuts against the outer wall of the telescopic rod 13, and the height position of the telescopic rod 13 is locked by friction; when loosened, the telescopic rod 13 can be released for easy height adjustment.

[0023] When using, release the brake on the universal wheel 3, push the device to the performance or practice position (such as next to the piano or a designated area on the stage), and lock the brake on the universal wheel 3 to ensure the device is stable and does not slip. If the device tilts slightly after placement, the center of gravity can be balanced by adjusting the position of the counterweight 26 inside the base 1. Loosen the locking valve 14, hold the base plate 4 and move the telescopic rod 13 up and down to adjust the placement plate 6 to a suitable viewing height (e.g., level with eye level when sitting, and slightly below eye level when standing). After adjustment, tighten the locking valve 14 to lock the telescopic rod 1. 3. Loosen the locking bolt 23 between the card holder 25 and the card block 24, rotate or move the card block 24 so that the placement plate 6 faces the user. After adjustment, tighten the bolt to fix it. According to viewing habits, rotate the threaded rod 22 of the hinge structure to drive the slide 21 to slide along the linkage groove. Through the linkage of the first hinge block 28, the hinge shaft 20, and the second hinge block 19, the placement plate 6 is tilted around the rotation axis of the rectangular block 5 (the angle can usually be adjusted between 30 and 60 degrees). After adjusting to a comfortable angle, the threaded rod 22 and the locking bolt 23 will be locked. The self-locking mechanism automatically fixes the angle, aligning the bottom edge of the sheet music with the positioning strip 11 of the placement plate 6, and placing it flat on the placement plate 6. Based on the width of the sheet music, rotating the left-side limiting screw 10 drives the two side sliders 16 to move along the slide groove 9 (the right-side slider 16 slides synchronously along the slide rod 27), aligning the anti-drop limiting components with the two sides of the sheet music. Pulling up the lifting rod 15 moves the pressure plate 18 upwards (compressing the spring 17), placing the edge of the sheet music below the pressure plate 18. Releasing the lifting rod 15 resets the spring 17, pushing the pressure plate 18 to press the sheet music firmly, preventing it from falling off. When in use, detach the LED light 8, turn on the LED light 8, and the lampshade 7 will focus the light on the sheet music area to ensure that the notes and symbols are clearly visible, improving the convenience of reading music. Remove the sheet music and turn off the LED light 8. Loosen the threaded rod 22, fold the placement plate 6 to fit against the base plate 4, and rotate the limiting screw 10 so that its end is screwed into the limiting hole of the rectangular block 5 to fix the folded state. Loosen the locking valve 14, retract the telescopic rod 13 into the support cylinder 2, and tighten the locking valve 14. Release the brake of the universal wheel 3, push the device to the storage position, and lock the brake.

[0024] like Figure 4 or Figure 5As shown, the anti-fall-off limiting assembly includes a vertical plate 12 fixedly installed on the upper end of the slider 16, a lifting rod 15, a spring 17, and a pressure plate 18. A sliding groove is provided in the vertical plate 12, and the pressure plate 18 is slidably installed in the sliding groove. The spring 17 is fixedly installed between the pressure plate 18 and the vertical plate 12. The lifting rod 15 is slidably installed in the vertical plate 12 and fixedly connected to the pressure plate 18, used to drive the pressure plate 18 to move. During the above-mentioned use, the limiting screw 10 is rotated according to the width of the musical score (because the limiting screw 10 and the slider 16...). The threaded connection allows the slider 16 to slide along the groove 9 during rotation, or pushes the slider 16 on the other side to slide along the slide rod 27, so that the anti-drop limiting components on both sides match the width of the sheet music; then pull the lifting rod 15 upward, the lifting rod 15 drives the pressure plate 18 to move upward along the sliding groove of the vertical plate 12, and at the same time compresses the spring 17; place the edge of the sheet music under the pressure plate 18, release the lifting rod 15, the spring 17 resets and pushes the pressure plate 18 downward, tightly pressing the edge of the sheet music, preventing the sheet music from shifting or falling off due to wind or collision during performance.

[0025] like Figure 6 As shown, the hinge structure includes a second hinge block 19 located at the bottom of the placement plate 6. A linkage groove is provided at the upper end of the base plate 4, and a slide block 21 is slidably installed within the linkage groove. The first hinge block 28 is fixedly connected to the slide block 21. The second hinge block 19 is hinged to the first hinge block 28 via a hinge shaft 20. A threaded rod 22 for adjusting the angle of the placement plate 6 is also threaded onto the locking bolt 23. During use, if it is necessary to adjust the tilt angle of the placement plate 6 to optimize the viewing angle, the threaded rod 22 is rotated. (Threaded rod 22 is threadedly connected to locking bolt 23). Threaded rod 22 will push or pull slide 21 to slide in the linkage groove of base plate 4. When slide 21 moves, through the hinge relationship between first hinge block 28, hinge shaft 20 and second hinge block 19, it will drive placement plate 6 to rotate around the rotation axis of rectangular block 5, thereby changing the tilt angle. After adjusting to a suitable angle, the thread self-locking characteristic of threaded rod 22 and locking bolt 23 can fix the position of slide 21, so that placement plate 6 maintains the current angle stability.

[0026] like Figure 1 As shown, the placement plate 6 can be folded relative to the base plate 4, and the telescopic rod 13 can be retracted into the support cylinder 2. After folding and retracting, the overall volume of the device is reduced to improve portability. In the above-mentioned use process, first loosen the lock of the threaded rod 22 in the hinge structure, push the placement plate 6 to rotate around the rotation axis of the rectangular block 5, so that it fits against the base plate 4 to complete the folding; then loosen the locking valve 14, retract the telescopic rod 13 downward into the support cylinder 2 (to minimize the height), and tighten the locking valve 14 to fix it; through folding and retracting, the overall length, width and height of the device are greatly reduced, making it easier to transport, carry or store, especially suitable for scenarios where you need to go out to perform.

[0027] like Figure 1 or Figure 3As shown, the LED light 8 is installed inside the lampshade 7, which is fixed to the edge of the placement plate 6. The illumination area of ​​the LED light 8 covers the sheet music placement area of ​​the placement plate 6. During the above-mentioned use, when the ambient light is dim (such as insufficient indoor lighting or at night), the LED light 8 is turned on, and the lampshade 7 will concentrate and reflect the light of the LED light 8 onto the sheet music placement area of ​​the placement plate 6, avoiding insufficient brightness caused by light scattering in all directions. At this time, the details such as notes, symbols, and words on the sheet music are clearly visible, reducing the error in reading the sheet music caused by light problems and improving the fluency of playing or practicing.

[0028] like Figure 3 As shown, the support cylinder 2 is a hollow cylinder with a smooth inner wall, which slides in conjunction with the outer wall of the telescopic rod 13. The locking valve 14 is a knob-type locking component that passes through the support cylinder 2 and abuts against the outer wall of the telescopic rod 13, so that the height of the telescopic rod 13 inside the support cylinder 2 is adjustable and locked. During the above-mentioned use, when it is necessary to adjust the height of the placement plate 6 to suit the user's height or usage scenario, loosen the locking valve 14 (the knob design is convenient for manual operation). Since the inner wall of the support cylinder 2 is smooth and slides in conjunction with the outer wall of the telescopic rod 13, the telescopic rod 13 can move smoothly up and down along the support cylinder 2. When the height is adjusted to the required position (such as being level with the user's line of sight), tighten the locking valve 14 so that it passes through the support cylinder 2 and abuts tightly against the outer wall of the telescopic rod 13, locking the telescopic rod 13 through friction to ensure that the height does not change during use.

[0029] like Figure 3 As shown, the base 1 has a multi-compartment structure for its accommodating cavity. The counterweight 26 can be installed and removed into different compartments according to the device's balance requirements. The casters 3 are silent casters with brakes, evenly distributed at the bottom of the base 1. After the placement plate 6 is folded, the limiting screw 10 can be screwed into the preset limiting hole of the rectangular block 5 to limit the folding of the placement plate 6. During the above-mentioned use, if the device's center of gravity shifts due to reasons such as placing a thick sheet music on one side, the counterweight 26 can be removed from one compartment of the base 1's accommodating cavity and installed into the other compartment. The counterweight distribution can be adjusted to balance the device. When moving the device, the silent casters 3 with brakes can reduce rolling noise and avoid disturbing others. After the placement plate 6 is folded, the limiting screw 10 can be rotated so that its end is screwed into the preset hole or groove of the rectangular block 5 to mechanically limit the folded placement plate 6, preventing the placement plate 6 from accidentally unfolding during carrying or storage and maintaining the compactness of the device after folding.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
