Problems solved by technology

[0002] Mechanical mechanism is an important content in the course of mechanical principles. Because some mechanical mechanisms are heavy and inconvenient to carry, it is inconvenient for the teacher to take them to the classroom to explain to students, and it is inconvenient to store them. Therefore, , we need a teaching demonstration device that facilitates the simulation of mechanical principles

Embodiment 1

[0026] Embodiment one: wherein one group of said screw mandrel 22 stretches out one end of storage box 1 and is fixed with motor, and the bottom of storage box 1 is provided with outlet.

[0027] Working principle: When demonstrating the mechanical mechanism 13, first start the motor, the motor drives the screw rod 22 connected to it to rotate, the screw rod 22 drives the fixed collar 21 connected to it to move, the two sets of fixed collars 21 are far away from each other, and the fixed sleeve The ring 21 drives the third connecting rod 20 connected to it to move together, so that the angle between the two groups of third connecting rods 20 increases, thereby driving the first fixing plate 2 to move upward, and the first fixing plate 2 drives the connecting rod 20 to move upward. The universal wheels move together, and at the same time, the fixed collar 21 drives the second connecting rod 23 connected to it to move, and the included angle between the two groups of second conne...
