12V Linear Actuator

https://www.zwldmachine.com/products/12v-linear-actuator/

A 12v linear actuator is an electromechanical device that converts electrical energy (from a 12-volt power source) into linear motion, meaning it moves in a straight line rather than rotating like a motor. It's commonly used to push, pull, lift, or tilt objects. Linear actuators are widely used in various industries, including automation, robotics, furniture design, automotive, and medical equipment.
