description	The utility model discloses a phase-control straight-pull type bistable permanent magnetic mechanism with a built-in switching-on spring, and the mechanism comprises a square sealing plate (1), a circular sealing plate (12), a core shaft (4), a movable iron core (7), a permanent magnet (8), and the switching-on spring (10), wherein the square sealing plate (1) and the circular sealing plate (12) are disposed on the core shaft (4). The central part of the core shaft (4) is provided with the movable iron core (7) in a sleeving manner. The switching-on spring (10) is disposed between the movable iron core (7) and the core shaft (4). An end part of the square sealing plate is provided with a first coil assembly (2a), and an end part of the circular sealing plate (12) is provided with a second coil assembly (2b). The permanent magnet (8) is disposed between the first coil assembly (2a) and the second coil assembly (2b). The first coil assembly (2a), the second coil assembly (2b) and the permanent magnet (8) are all disposed at the periphery of the movable iron core (7). According to the utility model, there is no need to adjust the opening range and over travel of a vacuum tube specially, and the opening range and over travel of the vacuum tube are guaranteed by the mechanism. The mechanism is high in safety and reliability.
