Scissors mechanism

A scissors mechanism uses linked, folding supports in a criss-cross 'X' pattern.

The scissor mechanism is a mechanical linkage system used to create vertical motion or extension. It consists of a series of interconnected, folding supports that resemble the shape of a pair of scissors, hence its name. The scissor mechanism is widely employed in various applications, including scissor lifts, folding tables, adjustable height platforms, and automotive jacks.
