[0024] See also Figure 1 The inner wall of the connecting seat 1 passes through and is rotatably connected with a bidirectional screw rod 10. The bidirectional screw rod 10 is a prior art means. Two sections of threads with different rotation directions are made on a screw rod, which can allow two sets of sliders 11 to move in opposite directions to get closer or separate. The outer wall of the bidirectional screw rod 10 is threadedly connected with a slider 11. The slider 11 matches the bidirectional screw rod 10 and can slide on the bidirectional screw rod 10. The top of the slider 11 is hinged with a moving plate 13 through a hinge rod 12. The top of the slider 11 is hinged with one end of the hinge rod 12. Since the length of the hinged rod 12 is fixed, when the slider 11 moves one end of the hinged rod 12 inward, the other end of the hinged rod 12 will move the movable plate 13 upward. When the slider 11 moves one end of the hinged rod 12 outward, the other end of the hinged rod 12 will move the movable plate 13 downward. The other end of the hinged rod 12 is hinged to the bottom end of the movable plate 13. The movable plate 13 is slidably connected to the inner side wall of the connecting seat 1, and the top of the movable plate 13 is fixedly connected to the bottom end of the support frame 2.

[0025] See also Figure 1 and Figure 4The positioning mechanism includes a contact plate 8, which can fix the two sides of the piano score to prevent the piano score from falling during the flipping of the placement plate 7. The contact plate 8 is slidably connected to the inner wall of the placement plate 7. Two piano scores can be placed on the left and right outer walls of the placement plate 7 respectively. The contact plate 8 is provided with two groups, and the two groups of contact plates 8 are elastically connected by a positioning spring 9. When the contact plate 8 moves outward, the positioning spring 9 is stretched. When resetting, the elastic force of the positioning spring 9 is used to bring the contact plate 8 back to the original position, and the inner wall of the bottom end of the rotating shaft 3 is in contact with the resetting One end of the positioning spring 4 is fixedly connected. When the wedge block 5 moves downward, the reset spring 4 will be compressed. When resetting, the elastic force of the reset spring 4 is used to reset the wedge block 5. The other end of the reset spring 4 is fixedly connected to the bottom end of the wedge block 5. The wedge block 5 and the pressing plate 6 are respectively penetrated and slidably connected to the inner wall of the rotating shaft 3. The rotating shaft 3 is provided with grooves corresponding to the wedge block 5 and the pressing plate 6. The wedge block 5 is plugged into the inner wall of the support frame 2. The inner wall of the support frame 2 is provided with two sets of vertical grooves, which can allow the placement plate 7 to be flipped 180 degrees to allow the wedge block 5 to be plugged into the groove.

[0026] Working principle: First, when you need to place the piano score on the placement plate 7, you only need to pull the contact plate 8 outward and stretch the positioning spring 9 to place the two sides of the piano score between the contact plate 8 and the placement plate 7. Then release the contact plate 8 and use the reverse elastic force of the positioning spring 9 to reset the contact plate 8, so that the contact plate 8 clamps and fixes the two sides of the piano score.

[0027] When the piano score on the outer wall of the right end of the placement plate 7 is needed, it is only necessary to press the pressing plate 6 to move the wedge block 5 downward and initially compress the return spring 4 so that the inclined surface of the wedge block 5 can be squeezed, and then the rotating shaft 3 is rotated to turn the placement plate 7 180 degrees. At the same time, the inner wall groove of the support frame 2 will squeeze the inclined surface of the wedge block 5, allowing the wedge block 5 to continue to move downward and continue to compress the return spring 4. When the wedge block 5 coincides with the groove of the support frame 2 after flipping, the reverse elastic force of the return spring 4 is used to reset the wedge block 5, so that the wedge block 5 is plugged into the inner wall groove of the support frame 2. When limiting is needed, it is only necessary to release the pressing plate 6 and use the reverse elastic force of the return spring 4 to reset the wedge block 5 and the pressing plate 6, so that the wedge block 5 can completely enter the groove of the support frame 2, and the inclined surface of the wedge block 5 will not be squeezed by the inner wall of the support frame 2, thereby completing the limiting of the placement plate 7.

[0028] When the height of the entire support frame 2 and the placement plate 7 needs to be adjusted, it is only necessary to rotate the two-way screw rod 10 to allow the slider 11 to bring one end of the hinged rod 12 closer to each other, and the other end of the hinged rod 12 brings the hinged rod 12, the support frame 2 and the placement plate 7 upward to a certain height. When it is necessary to adjust downward, it is only necessary to rotate the two-way screw rod 10 in the opposite direction to allow the slider 11 to separate one end of the hinged rod 12 from each other, and the other end of the hinged rod 12 brings the movable plate 13, the support frame 2 and the placement plate 7 downward. The display height of the support frame 2 and the placement plate 7 can be adjusted according to actual conditions.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
