This reciprocating linkage model is a classroom apparatus designed for educational purposes education and experiments. Its small size brings the mechanism into clear view, making it easier to study how parts interact during motion.As an electric linkage model, it shows linear motion linkage behavior through a extendable rod, swiveling arms, and a visible mechanical layout. The iron shaft is marked with an extension range from 20 mm to 80 mm, creating about 60 mm of stroke that is useful for watching the movement cycle in detail.The construction pairs a light wood finish base board with metal rod elements and connector or bracket pieces in blue, white, orange, and goldenrod Multiple pre drilled mounting holes are included, and the side board holes are indicated as a.9 mm for use with 2 mm or 2.3 mm diameter screws, helping support classroom setup and experiment work.With its visible linkage mechanism and hands on structure, this reciprocating linkage model is well suited for students who need to observe movement transfer, compare positions, and understand how linear motion linkage operates in practice.
