The drive motor 2 is laid flat in the internal space of the housing 1, and a worm gear 22 is disposed on the rotating shaft 21 of the drive motor 2. The toggle component 3 includes a rotating shaft 21. The shaft 31 and the actuating cam 32 are arranged on the shaft 31. The rotating shaft 31 is equipped with a turbine 33 that meshes with the worm gear 22. The rotating shaft 31 is movably fitted on the shaft support 111, and the turbine 33 is positioned between the two shaft supports 111. The actuating cam 32 is positioned in the limiting groove 121, and a limiting ring 34 is formed at one end of the rotating shaft 31 near the actuating cam 32. The limiting ring 34 protrudes from the second half shell 12 and is limited by the outer wall surface of the limiting groove 121.

[0023] In the actuator of this utility model, the rotating shaft 31 of the actuating element 3 and the turbine 33 on the rotating shaft 31 are positioned by two shaft columns 111 within the internal space of the housing 1. At the same time, the limiting groove 121 in the external space of the housing 1 forms a limiting position for the actuating cam 32 of the actuating element 3, and the limiting ring 34 on the rotating shaft 31 of the actuating element 3 is limited by the outer wall surface of the limiting groove 121. The cooperation of the above three points ensures that the actuating element 3 does not shift on the housing 1, and the drive motor 2 is laid flat in the internal space of the housing 1, which makes the cooperation between the drive motor 2 and the actuating element 3 more stable, thereby solving the technical problem of poor positioning of the end actuating element 3 in the actuator of the prior art.
