An active adhesive piece is nested and installed on the outside of the guiding connecting rod. A second adhesive airbag is adhesively connected to the inner side of the end of the guiding connecting rod, and the second adhesive airbag is docked with the lower end of the active adhesive piece. A second air delivery hose is installed through the outside of the active adhesive piece, and the second air delivery hose extends along the guiding connecting rod to the inside of the active connecting piece. At the same time, the second air delivery hose is connected to the first adhesive airbag. A receiving cavity is formed at the end of the guiding connecting rod, and a fitting docking layer is adhesively connected to the end of the receiving cavity. A raised piece is fixedly connected to the outside of the active adhesive piece, and the raised piece corresponds to the position of the fitting docking layer.

[0010] Further, the active connecting piece is provided with a first towing rope and a secondary positioning piece. The first towing rope is wound around the shaft end of the active connecting piece. A secondary positioning piece is rotatably connected to the outside of the music score stand body, and the shaft end of the secondary positioning piece is docked with the end of the first towing rope.

[0011] Further, the secondary positioning piece faces the opposite direction to the active connecting piece. At the same time, the secondary positioning piece and the active connecting piece form opposite rotation directions through the first towing rope. When the active connecting piece rotates inward, the secondary positioning piece rotates outward.

[0012] Further, the docking pedal is provided with a reserved first airbag, a first air delivery hose, and a reserved second airbag. The reserved first airbag is adhesively connected to the lower end of the docking pedal, and the reserved first airbag is docked with the inside of the music score stand body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The multifunctional folding music score stand for music teaching is provided with a self-turning page structure. During the process of the user performing, there is no need to free up the hand. Just step on the docking pedal according to the need, and through the air supply state between the reserved second airbags, the movable docking block can be stably pushed outward, so that it cooperates with the docking traction rope to stably drive the movable connecting piece to rotate inward, and then cooperate with the subsequent guiding connecting rod and the movable adhesive piece to adsorb and turn a single page of paper, avoiding the disadvantages of the prior art that the number of pages turned over at one time cannot be guaranteed by the electric structure for page turning, and the page turning frequency cannot be controlled;

[0020] 2. The multifunctional folding music sheet stand is provided with an automatic detachment structure. As the guiding connecting rod is forced to move outwards, the bonded airbag under synchronous pressure will steadily push the movable bonding part outwards through its stable air supply state. The fitting docking layer and the protruding part in synchronous contact will supply adhesive mucus to the movable bonding part in real time, enabling it to adsorb the contacted paper. At the same time, as the user releases the force application state of the footstep, the reset guiding connecting rod and the movable bonding part will traction the adsorbed paper to turn over. Along with the reset contraction of the guiding connecting rod and the movable bonding part, the adsorbed paper will automatically turn to the corresponding position and then fall off the suction state, stably performing the automatic page-turning process;

[0021] 3. The multifunctional folding music sheet stand is provided with a subsequent self-positioning processing structure. The rotation directions of the movable connecting part and the secondary positioning part are opposite. When the movable connecting part is forced to rotate inwards to perform the work of adsorbing and turning over the paper, the secondary positioning part docked with it through the traction rope will be in the unfolded state. And when the movable connecting part cooperates with the guiding connecting rod and the movable bonding part to complete the page-turning and reset of the adsorbed paper, the secondary positioning part out of the stressed state will rotate inwards through the torsion spring force at the shaft end to perform self-positioning processing on the outer side of the paper.
