The operating steps of the present invention are:

When using the device, first move the device to a suitable position, then start the motor 413, the motor 413 can drive the worm 412 to rotate through the rotating rod of its output shaft, and the worm 412 is respectively engaged with the two worm gears 410 for transmission, and then It can drive two rotating shafts 49 to rotate, and the direction of rotation between the two rotating shafts 49 is opposite. The rotation of the two rotating shafts 49 can drive the two recesses under the mutual cooperation between the set gear 2 48 and the toothed plate 2 46. Relatively move between the shaped frames one 45, and the relative movement between the two concave frames one 45 can drive the concave frame under the interaction between the set U-shaped rod one 42, the U-shaped rod two 411 and the push plate 43. The shaped frame 10 moves up and down, and then drives the adjustment plate 17 to move up and down, so that the device can adjust the height of the position of the adjustment plate 17 according to the needs of the user. When the position of the adjustment plate 17 is Turn off the motor 413 after the height adjustment is finished;

When the device needs to drive the adjustment plate 17 to rotate during use, so as to adjust the orientation of the adjustment plate 17, the adjustment plate 17 can be conveniently driven by turning the adjustment plate 17 under the action of the rotating rod 24 provided. Rotate, and then realize the adjustment of the orientation of the adjustment plate 17, during the rotation of the adjustment plate 17, the mutual cooperation between the set arc slider 22 and the arc chute 23 can increase the stability of the adjustment plate 17 during rotation When the rotation of the adjusting plate 17 is finished, start two hydraulic rods one 9, and the two hydraulic rods one 9 drive the movable plate 6 to move upward, and then can drive the end face gear 15 arranged on the movable plate 6 to move upward until End face gear one 5 is meshed with end face gear two 25, close hydraulic lever one 9 at this moment, can limit the rotation of rotating rod 24 under the mutual cooperation between set end face gear one 5 and end face gear two 25, thereby can be opposite to The adjusting plate 17 plays a fixed role, avoiding the continuous rotation of the adjusting plate 17;

When the device needs to adjust the inclination angle of the adjustment plate 17 during use, first turn the turntable provided at the left end of the threaded rod 20 to drive the second threaded rod 20 to rotate, and the rotation of the threaded rod 20 can drive the connecting plate 18 to move to the left , and then can drive the two toothed plates-13 to move to the left, the two toothed plates-13 are meshed with the two gears-30 respectively, and then can drive the fixed rod-12 to rotate, through the rotation of the fixed rod-12 Under the action of the provided connecting block 14, the adjustment plate 17 can be driven to rotate upwards around the fixed rod-12 until the adjustment plate 17 rotates to a suitable angle, thereby realizing the adjustment process of the inclination angle of the adjustment plate 17, which is convenient for teachers in the teaching process. Adjust the inclination angle of the adjustment board 17 according to the needs of the user, so that the teaching music score placed on the adjustment board 17 can be conveniently viewed;

When the adjustment plate 17 is in an inclined state, in order to avoid the tendency of the teaching music score placed on the adjustment plate 17 to fall, firstly drive the set rotation stopper 117 to rotate to 90 degrees, so that the rotation stopper 117 overlaps with the through groove 115 At this time, under the action of the two springs 113 provided, the L-shaped support plate 111 can be driven to move upwards, and then the lower end of the teaching score is pressed against the L-shaped support plate 111. At this time, the set L-shaped support plate 111 It can play a supporting effect on the teaching score, and avoid the tendency of the teaching score placed on it to fall due to the large inclination angle of the adjustment plate 17. When the L-shaped support plate 111 is used, press the L-shaped support plate downward 111 and then under the action of the set vertical bar 3 114, the set rotation block 117 can be driven to move downward until the rotation block 117 passes through the through groove 115 and moves to the lower side of the limiting plate 116, and then drives the rotation block 117 Rotate 90 degrees, at this time, the fixing effect on the L-shaped support plate 11 can be realized under the mutual cooperation between the set limit block 117, the limit plate 116 and the vertical bar 114, and the L-shaped bar can be supported to a certain extent.
