[0002] The lyre is a widely used musical instrument in ancient Greek and Roman culture. It has an arc-shaped resonance box and strings. The lyre was widely used in ancient times to accompany and play ancient poetry, so it is also called the lyre. It became popular again during the Renaissance and became one of the important symbols of Western music.

[0003] At present, the stand for placing lyre sheet music is generally a vertical stand, that is, it stands directly on the ground at a certain height. Therefore, it has certain limitations in use and cannot be placed on a desktop or a table with a certain height. In a smaller venue or limited space, there may not be enough ground space to place the stand, which brings inconvenience to the user and has low applicability. Utility Model Content

[0004] The utility model aims to provide a music score stand which can be selected to stand on the ground or on a desktop for use according to the needs of users.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0007] It can be seen that, through the setting of the fixing mechanism, the telescopic bracket and the frame plate can be connected together or used separately, so that the user can choose to use it on the ground or on the table according to the needs of the user, and the applicability is wide. If the bracket needs to be placed on the table for use during performance, only the frame plate needs to be carried, which reduces the occupied space and is easy to carry. When the angle of the frame plate needs to be adjusted, only the fastening bolts need to be loosened. After the angle of the frame plate is adjusted, the fastening bolts can be tightened. The structure is simple and easy to use.

[0008] Furthermore, the fixing mechanism includes a protrusion installed on the outer surface of the disc, a pin is inserted into the inside of the protrusion, a hole is opened on the outer surface of the plug block, and the pin is plugged into the hole, a pull block is installed at the end of the pin away from the hole, a first spring is connected to the outer surface of the pull block, and the end of the first spring is connected to the protrusion.

[0009] When the shelf needs to be placed on a desktop for use, the pull block can be pulled outward to drive the latch to be pulled out from the connecting rod, so that the plug block can be separated from the slot and the disc can be placed on the desktop for use. When the shelf needs to be placed on the ground for use, the plug block only needs to be inserted into the slot. The arc surface at the upper end of the plug block is pressed against the arc surface at the end of the latch, so that the plug block can be directly inserted into the interior of the slot. Under the action of the elastic force of the first spring, the latch can be automatically inserted into the insertion hole to fix the plug block, so that the telescopic bracket can be quickly connected to the shelf for use when placed on the ground.

[0010] Furthermore, three suction cups are installed on the lower surface of the disk, and the three suction cups are distributed in an array around the central axis of the disk.

[0011] By setting the suction cup, the disc can be stably adsorbed on the desktop, so that the shelf can remain stable and avoid shifting when turning the music score.

[0012] Furthermore, three through holes are opened inside the disc, and the through holes are connected to the inside of the suction cup. The outer surface of the connecting rod is sleeved with a movable disc, and the lower surface of the movable disc is connected to three sealing plugs, and the sealing plugs correspond to the through holes.

[0013] By sliding the movable plate upward, the three sealing plugs can be driven to be drawn out from the through holes at the same time, thereby achieving the purpose of breaking the vacuum of the suction cup, making it easy to take the disc off the desktop.

[0014] Furthermore, a sleeve is sleeved on the outer surface of the connecting rod, and the bottom of the sleeve is connected to the movable disk, a shoulder is provided on the outer surface of the connecting rod, a second spring is sleeved on the outer surface of the connecting rod, and both ends of the second spring are respectively abutted against the shoulder and the sleeve.

[0015] By holding the sleeve and sliding it upward, the sealing plug can be easily pulled out of the through hole to break the vacuum, and under the elastic force of the second spring, when the sleeve is released, the movable disk can be pushed to slide downward again, so that the sealing plug blocks the through hole, and the bottom of the movable disk is in close contact with the upper surface of the disc, thereby improving the sealing effect on the through hole.

[0016] Furthermore, a limiting sliding groove is provided on the outer surface of the connecting rod, a limiting sliding block is provided inside the limiting sliding groove, and an end of the limiting sliding block is connected to the inner wall of the sleeve.

[0017] By limiting the position setting of the limiting slide groove and the limiting slider, the movable plate can only slide up and down along a fixed angle, ensuring that the sealing plug can block the through hole every time the movable plate descends, thereby improving the portability of the operation.
