s1, firstly placing twenty-four solar terms labels, enabling a T-shaped operating rod (25) to move upwards when placing the twenty-four solar terms labels, enabling the T-shaped operating rod (25) to drive a pressing plate (26) to move upwards and press a second spring (27) to contract, placing the solar terms labels on a label placing plate (3), loosening the T-shaped operating rod (25), driving the pressing plate (26) to move downwards by using the elasticity of the second spring (27) to compress the solar terms labels, then adjusting the position of the other pressing plate (26) by using a trapezoidal block (23) to realize compression, and placing the twenty-four solar terms labels in sequence;
s2, when teaching and learning, a student takes an iron ball (6) and puts the iron ball into the annular track (4), the iron ball (6) slides in the annular track (4), the friction effect is slower and slower when the iron ball slides, the iron ball (6) is enabled to be stable and static under the attraction effect of the magnet plate (20) on the iron ball (6) when the sliding acting force tends to zero, at the moment, the magnet plate (20) slides upwards on the surface of the guide rod (17) through the guide plate (18) and presses the first spring (22) to contract, the first wedge (21) synchronously moves upwards along with the magnet plate (20) and is in contact fit with the second wedge (31), the second wedge (31) is driven to drive the sliding rod (30) to move and press the third spring (34) to contract, and the sliding rod (30) drives the label placing plate (3) to rotate and expand under the effects of the two U-shaped blocks (33) and the articulated arm (32);
s3, the student pulls the locking operation plate (45) to drive the locking rod (43) to move, the locking rod (43) drives the locking block (44) to be separated from the locking groove and extrude the spring IV (46) to contract, the rotary disc (2) is rotated until the unfolded label placing plate (3) and the magnifying lens cone (10) are in the same straight line, the student can penetrate through the unfolded label placing plate (3) through the magnifying lens cone (10), then the locking operation plate (45) is loosened, and the locking block (44) is driven to be clamped into the locking groove at the position under the action of the spring IV (46);
s4, the student can look over the throttle label on the label that expands and place board (3) through magnifying lens cone (10) and carry out cognitive study, can rotate the hand wheel simultaneously during cognitive study and drive pivot two (36) and rotate, pivot two (36) drive screw post (37) and rotate, make fly leaf (38) drive magnifying lens cone (10) motion through connecting rod (39), adjust magnifying lens cone (10) and label and place the distance between the throttle label on board (3), and then can experience the physics of magnifying lens cone (10) and enlarge the effect more, it is big more to leave to be more near, it is little to leave to enlarge the effect more far away.
