Sewing machine pedal mechanism

The model functions as a classic crank rocker mechanism, with the sewing machine pedal serving as its core component. To operate it, swing the foot pedal forward and backward with your foot, utilizing its inherent motion to activate the system. As you work it, note that the foot pedal itself is the primary rocker within the crank rocker mechanism, driving the process forward. Meanwhile, the crank and pulley are relegated to passive roles as followers, reacting to the pedal's movement. The connecting rod, painted yellow, serves as a critical link between key components, while the blue frame provides essential structural support.
