[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] See Figures 1-8As shown, this utility model provides an adjustable auxiliary device for vocal training, including a shelf body 1 and a telescopic support rod 4. A sheet music fixing component 2, capable of holding sheet music of different sizes, is combined and arranged between the two sides of the shelf body 1. Specifically, the sheet music fixing component 2 includes a guide groove 207, a mounting plate 201, and a metal clip 202. Guide grooves 207 are provided laterally on both the front and rear sides of the top of the shelf body 1, and the guide grooves 207 are vertically through grooves. Two mounting plates 201 are respectively arranged longitudinally at the ends of the guide grooves 207. Metal clips 202 are fixedly installed on the top surface of each mounting plate 201, and on both sides... The metal clips 202 are symmetrically distributed. Guide studs 205 are vertically installed at the front and rear positions of the bottom of the mounting plate 201. The guide studs 205 and guide grooves 207 correspond to each other and pass through the corresponding guide grooves 207 in a sliding fit. At the same time, the part of the guide stud 205 extending out of the corresponding guide groove 207 is coaxially engaged with the limit nut 204. The purpose of this arrangement is that by using the guide studs 205 of the music score fixing part 2 to slide along the guide grooves 207 and tightening the limit nut 204, the distance between the metal clips 202 on both sides can be adjusted. The method of adjusting the distance between the metal clips 202 on both sides is simple and easy to operate.

[0034] See Figures 1-4 As shown, the bottom of the shelf body 1 is equipped with a tilt adjustment component 6 that can adjust the tilt angle of the shelf body 1. Specifically, the tilt adjustment component 6 includes a U-shaped bracket 605 and a connecting arm 601. The bottom of the U-shaped bracket 605 is detachably assembled with the telescopic part 402 via a disassembly assembly 7. The U-shaped notch of the U-shaped bracket 605 faces upward, and a support screw 603 is horizontally inserted between the two sides of the U-shaped bracket 605 through a sliding fit. The end of the support screw 603 extending out of the U-shaped bracket 605 is coaxially fixed with an anti-detachment end 606 whose outer diameter is larger than the outer diameter of the support screw 603. The end of rod 603 extending out of the other side of U-shaped bracket 605 is coaxially fitted with a locking knob 602 that can reciprocate along the axial direction of support screw 603. Connecting arms 601 are vertically fixed on both sides of the bottom surface of the shelf, and support screws 603 pass through the lower part of connecting arms 601 in a coaxial tight fit. The advantage of this arrangement is that, by using the connecting arms 601 and support screws 603 of the tilt adjustment component 6 to deflect around U-shaped bracket 605 and tightening the locking knob 602, the tilt angle of shelf body 1 can be adjusted. The tilt angle adjustment of shelf body 1 is simple and easy to implement.

[0035] See Figures 1-8As shown, the bottom of the tilt adjustment component 6 is equipped with a disassembly assembly 7. A telescopic support rod 4 is coaxially arranged below the disassembly assembly 7. The tilt adjustment component 6 is detachably assembled with the telescopic part 402 vertically arranged at the top of the telescopic support rod 4 via the disassembly assembly 7. This allows the shelf body 1 and the tilt adjustment component 6 to be detachably assembled together on the top of the telescopic part 402 via the disassembly assembly 7. Specifically, the disassembly assembly 7 includes a limiting hole 706 and a mating sleeve 703. A limiting hole 706 is horizontally formed at the upper part of part 402. A mating sleeve 703 is vertically fixed at the bottom of the U-shaped bracket 605. The mating sleeve 703 is fitted onto the top of the telescopic part 402 by a vertical sliding fit. A mounting hole 705 is horizontally formed on the outer periphery of the mating sleeve 703. The mounting hole 705 is a through hole and is horizontally coaxial with the limiting hole 706. A limiting rod 704 is coaxially inserted into the mounting hole 705 by a sliding fit. The inner end of the limiting rod 704 is aligned with the limiting hole 706. 6. A horizontal sliding fit is provided. The outer end of the limiting rod 704 is coaxially fixed with a handle 701. The portion of the limiting rod 704 located between the handle 701 and the outer periphery of the fitting sleeve 703 is coaxially fitted with a spring 702. Both ends of the spring 702 are fixedly connected to the handle 701 and the outer periphery of the fitting sleeve 703, respectively. The purpose of this arrangement is that, by vertically sliding the fitting sleeve 703 of the disassembly assembly 7 with the top of the telescopic part 402 of the telescopic support rod 4 and horizontally sliding the limiting rod 704 with the limiting hole 706, the shelf body 1 and the tilt adjustment component 6 can be detachably assembled together on the top of the telescopic part 402. At the same time, by simply pulling the limiting rod 704 out of the limiting hole 706, the fitting sleeve 703 can slide vertically upward and separate from the top of the telescopic part 402. In this way, the shelf body 1 and the tilt adjustment component 6 can be detached together from the top of the telescopic part 402. The assembly and disassembly of the shelf body 1 and the tilt adjustment component 6 on the top of the telescopic part 402 are simple and easy to implement.

[0036] See Figures 1-8 As shown, the following optimizations have been made to this application. Specifically, a stable base 5 is fixedly placed flat at the bottom end of the telescopic support rod 4, and multiple anti-slip pads 501 are fixed around the bottom surface of the stable base 5. This arrangement facilitates the use of the stable base 5 to maintain the telescopic support rod 4 and the shelf body 1 in a raised and stable position, making it convenient to lay the sheet music flat. At the same time, the anti-slip pads 501 prevent the stable base 5 from moving accidentally. Further optionally, the telescopic support rod 4 is a two-section pull-out telescopic rod with a locking screw 401, and the telescopic part 402 is the upper section, so that the overall length of the telescopic support rod 4 can be adjusted by pulling out the telescopic part 402 and tightening the locking screw 401, making it easy for users of different heights to use. Furthermore, a fall-prevention baffle 3 is vertically extended and fixed to the lower edge of the shelf body 1, so that when the shelf body 1 is used at an angle, the fall-prevention baffle 3 can prevent the sheet music from accidentally sliding off the surface of the shelf body 1 and falling to the ground.

[0037] See Figures 1-8 As shown, the guide grooves 207 are all horizontally placed waist-shaped elongated grooves, and the mounting plates 201 are all vertically placed rectangular plates. The outer edges of the mounting plates 201 on both sides, which are far apart from each other, are vertically extended and fixedly connected to force-applying wing plates 203. This arrangement ensures that the guide grooves 207 have a sufficiently wide adjustment range in the lateral direction, allowing the metal clip 202 to be adjusted to a suitable position. It also facilitates the sliding of the guide studs 205 along the guide grooves 207 by holding the force-applying wing plates 203 during the adjustment of the metal clip 202's position. Optionally, the limiting nuts 204 are all hand-tightened knurled nuts, and the rear end of each guide stud 205 is coaxially mounted with a handle 206, allowing the limiting nuts 204 to be directly turned by hand and preventing accidental detachment of the limiting nuts 204 from the rear end of the guide studs 205. Furthermore, the connecting arms 601 on both sides contact the inner side of the corresponding side of the U-shaped bracket 605 to prevent the connecting arms 601 from moving laterally between the U-shaped brackets 605. The part of the support screw 603 located between the locking knob 602 and the outer side of the U-shaped bracket 605 is coaxially slidably fitted with an anti-loosening washer 604, and the locking knob 602 presses the anti-loosening washer 604 tightly against the outer side of the U-shaped bracket 605. This arrangement makes it easier to improve the locking stability of the tilt angle of the shelf body 1 by tightening the anti-loosening washer 604.

[0038] Using the above structure, specifically in the process of placing and holding sheet music during vocal training, sheet music fixing components 2 capable of holding sheet music of different sizes are combined and arranged between the two sides of the shelf body 1. Then, by means of the guide studs 205 of the sheet music fixing components 2 sliding along the guide grooves 207 and tightening the limit nuts 204, the distance between the metal clips 202 on both sides can be adjusted. The method of adjusting the distance between the metal clips 202 on both sides is simple and easy to operate, thereby facilitating the clamping of the metal clips 202 on both sides. The sheet music holder 2 is designed to hold sheet music of different sizes, allowing for flexible adjustments based on the actual size of the sheet music used in vocal training. Furthermore, the bottom of the shelf body 1 is equipped with an angle adjustment component 6, which allows for adjustment of the shelf body 1's tilt angle. By using the connecting arm 601 and support screw 603 of the angle adjustment component 6 to rotate around the U-shaped bracket 605 and tightening the locking knob 602, the tilt angle of the shelf body 1 can be adjusted. The entire design is simple and easy to implement, allowing for adaptive adjustments to the tilt angle of the shelf body 1 and the sheet music according to the user's actual needs, further enhancing its flexibility. Furthermore, by vertically sliding the fitting sleeve 703 of the assembly 7 against the top of the telescopic support rod 402 and horizontally sliding the limiting rod 704 against the limiting hole 706, the shelf body 1 and the tilt adjustment component 6 can be detachably assembled together at the top of the telescopic part 402. Simultaneously, simply pulling the limiting rod 704 out of the limiting hole is sufficient to disengage it. After step 706, the mating sleeve 703 can slide vertically upwards and separate from the top of the telescopic part 402. This allows the shelf body 1 and the tilt adjustment component 6 to be removed from the top of the telescopic part 402 together. The assembly and disassembly of the shelf body 1 and the tilt adjustment component 6 on the top of the telescopic part 402 is simple and easy to achieve. It is convenient to use the shelf body 1 and the tilt adjustment component 6 together on the top of the telescopic part 402 for raising and placing sheet music. At the same time, it is convenient to remove the shelf body 1 and the tilt adjustment component 6 together from the top of the telescopic part 402 for storage and maintenance.
