Power phase controller based on single-chip microcomputer

The invention discloses a power phase controller based on a single-chip microcomputer, and relates to the technical field of electric power phase control, the power phase controller comprises a phase controller body and a mounting clamping seat, the outer wall of the phase controller body is clamped with the inner side wall of the mounting clamping seat, and an extrusion pre-tightening device is fixedly mounted on the inner side wall of the mounting clamping seat. And a pressed contact device is arranged on one side of the extrusion pre-tightening device. According to the invention, when the phase controller body is placed in the mounting clamping seat, a sealed compressed air bag is extruded through the extrusion pre-tightening device, so that the air pressure in the sealed compressed air bag is changed, and the air flow in the sealed compressed air bag flows into the sealed cavity through the air guide pipe; therefore, a sealing pushing and pressing block in the sealing cavity moves outwards under the thrus
