Sliding block actuator driven by fire

The invention relates to a sliding block actuator driven by fire. The sliding block actuator comprises an electric heating firing element (1), a top cover (2), a micro-detonator (3), a sliding block (4), a base (5), a detonating powder column (6), an explosion propagation hole (7) and work applying powder (8). The sliding block actuator driven by the fire is a fire actuation device and a work applying fire product, can serve as a security mechanism of a microelectromechanical system, combines the characteristics of small size, safety and reliability, guarantees the safety of the microelectromechanical system in a service process before actuation and the task finishing reliability of the microelectromechanical system after actuation, is the fire actuation device with excellent comprehensive performance, can provide beneficial references for the design of a similar actuation device, and has a good application prospect.
