This utility model relates to the field of actuator technology and discloses an actuator with automatic temperature and pressure control, including a lower actuator housing. The lower actuator housing is supported by a base plate fixed to its bottom, providing stable support for the overall structure. A stepper motor fixed to the surface of the lower actuator housing serves as the core power source. When external temperature or pressure signals trigger control commands, the stepper motor starts, and the drive gear fixed to its output end rotates synchronously with the motor's output shaft, transmitting power to subsequent gear transmission components. This provides initial power for the actuator's adjustment actions. The outer wall of the drive gear meshes with a spur gear, causing it to rotate. The top of the spur gear is rotatably connected to the inner wall of the lower actuator housing, and the bottom is rotatably connected to the inner wall of the base plate. This double support ensures stable rotation without deviation, preventing transmission failure due to gear wobbling. The rotation structure of the remaining spur gears is identical.
