The servo drive mechanism moves at the same time and rotates in the opposite direction. The lower end drives the slider to move upward through the second installation shaft, that is, the slider connecting shaft 7-1; when contracted, the lower toggle drives the slider to move downward. Due to the lever action of the toggle mechanism and its own accelerated downward potential energy, it can generate a greater punching force.

The servo motor is used to drive the crankshaft to rotate, so that the connecting rod pushes and pulls the toggle lever to both sides (front and back) to drive the slider to move up and down. The toggle lever is located at the outermost end of the slider. The pressure provided by the dual power is more balanced, avoiding the difficulties and cost factors in the design and selection of a single power.
