[0031] Depend on Figure 1 and Figure 2 It can be seen that the moving assembly includes a screw rod 35, a moving frame 36, a laser pen 37, a bolt 38 and a limit rod 39.

[0032] As can be seen from the above, first the staff inserts the laser pen 37 into the movable frame 36, and then tightens the bolts 38 to firmly fix the laser pen 37 and the movable frame 36. At this time, the laser pen 37 also passes through the protrusion on the fixed frame 34 and extends into the demonstration box body 1. Then the screw rod 35 is rotated to drive the movable frame 36 to move downward, so that the movable frame 36 is guided and limited by the limit rod 39 to stably drive the laser pen 37 to move downward, so that the position of the laser pen 37 can be flexibly adjusted to make the laser pen 37 align with a demonstration lens 32 on the isolation plate 31, and then the laser pen 37 cooperates with the four demonstration lenses 32 set as convex lenses, concave lenses, reflectors and prisms to demonstrate optics, so that the light trajectory can be well observed, thereby enhancing the optical demonstration effect, and then the bolt 38 is rotated to cancel the fixation of the laser pen 37, and the laser pen 37 can be disassembled for replacement or maintenance, so that the laser pen 37 can be easily disassembled and assembled.

[0037] As can be seen from the above, the staff starts the driver 42, so that the driver 42 drives the toothed disc 43 to rotate, and then through the meshing transmission between the toothed disc 43 and the four adjusting gears 48, the four adjusting screws 45 respectively drive the lifting rods 46 thereon to move upward, and the lifting rods 46 are guided and limited by the limiting plate 47, which can improve the stability of the lifting rods 46 during the lifting process, and then the height of the demonstration box body 1 can be stably adjusted by the four lifting rods 46 together, thereby effectively improving the stability of the optical demonstration box body 1 during the adjustment process. The use of this adjustment method is more convenient and quick, and it is more time-saving and labor-saving.
