The height of the engaging member is H, the first gap is G2, H≥G2 or H≤G2, and the engaging member can pass through the first gap.

[0080] When the panel 101 moves to the preset position of the socket 201, the first engaging member 1061 is engaged with the first limiting protrusion 2031, the second engaging member 1062 is engaged with the second limiting protrusion 2032, the third engaging member 1063 is engaged with the third limiting protrusion 2033, and the fourth engaging member 1064 is engaged with the fourth limiting protrusion 2034. Through the engagement between the four engaging members and the four limiting protrusions, the panel 101 is restricted above the socket 201.

[0081] In some embodiments, one pair of the above four engaging members and four limiting protrusions can be selectively retained. For example, the first engaging member 1061 and the first limiting protrusion 2031 can be retained, and the second gap is the gap between the second end of the first engaging member 1061 and the second side wall of the insertion slot.

[0082] In some embodiments, as Figure 9 As shown, a third side wall 2014 is provided at the first end of the insertion slot, and the third side wall 2014 is connected to at least one of the first side wall 2011, the second side wall 2012, and the bottom 2013 of the insertion slot. A first notch 205 allowing the panel 101 to pass through is provided on the third side wall 2014, and at least a part of the third side wall 2014 is reserved for the maximum width of the first notch 205. The panel 101 is inserted into the socket 201 from the second end of the insertion slot, and the third side wall 2014 is used to restrict the panel 101 from continuing to move after moving to the above preset position, so that the panel 101 is restricted above the socket 201 by the engaging member, the limiting protrusion, and the third side wall 2014.

The two through holes 1011 are both close to the first side 1016 and are arranged separately along the length direction of the first side 1016. Each through hole 1011 is provided with a page ring 102 that can be selectively opened. In some embodiments, the music score 50 is provided with holes through which the page ring 102 can pass, and the music score 50 can be selectively placed on the panel 101 through the page ring 102.

[0087] As Figure 15 and Figure 16 shown, in some embodiments, the music score board 10 further includes a loose-leaf 60. The loose-leaf 60 is provided with holes through which the page ring 102 can pass, and the loose-leaf 60 can be selectively placed on the panel through the page ring 102. The music score 50 can be placed in or taken out of the loose-leaf 60, and the music score 50 is restricted on the panel 101 by the loose-leaf 60.

[0088] As Figure 17As shown, in some embodiments, the page ring 102 includes a first half-ring 1021 and a second half-ring 1022. The first end of the first half-ring 1021 is rotatably connected to the first end of the second half-ring 1022, and the second end of the first half-ring 1021 and the second end of the second half-ring 1022 can be selectively opened or closed. In some embodiments, locking heads 1024 that can be locked to each other are provided at the second ends of the first half-ring 1021 and the second half-ring 1022.

[0089] As Figure 15 and Figure 17 As shown, in some embodiments, the panel 101 is provided with at least one page clip 103 for restricting the state of the music score 50 on the panel 101. In some embodiments, the page clip 103 is an elastic strip structure.
