In the such scheme, described each magnet steel also is being provided with the transition limit between limit, top wall and the inner side edge wall and between bottom side edge wall and inner side edge wall, and the basic configuration on described transition limit is the plane; The bottom side edge wall and the top Bian Bi of described each magnet steel are horizontally disposed with, and described transition limit vertically is provided with.
In the such scheme, the thickness of described each the magnet steel middle-end of described each magnet steel reduces from the middle-end to two ends gradually greater than thickness and its thickness of top and bottom.
In the such scheme, the thickness of described each magnet steel top and bottom is identical, and is symmetrical arranged.
In the such scheme, described casing is arranged with geometrical clamp outward.
The utlity model has positive effect: owing to adopted magnet steel and unique modified model shape of neodymium iron boron material, make it under the less situation of volume, still have higher actuating force in the utility model, thereby satisfy the designing requirement that improves day by day.
