👉 In physics and engineering, a "refastener" is a device that helps to slow down or stop an object. It can be used in various applications such as brakes, hydraulic systems, and other machinery designed to reduce friction and increase efficiency. Refastening devices typically consist of a spring, a damper, and a piston attached to the end of the spring. The purpose is to slow down the object by compressing it against the damper, which then releases the pressure when the object
