Rotary electromagnetic slide block connector

The utility model relates to an assembly for connecting the sliding block in a rotary solenoid valve, comprising a sliding block installed under a magnet rotator. The sliding block connects the magnet rotator via axial grooves or keys positioned at both sides of the sliding block. To match the sliding block thereof, the magnet rotator has axial keys or grooves at both sides, and the width of the matching key or groove on each side is different from that on the other side, i.e., the former is larger than the latter; otherwise, the radial grooves or keys are provided on the top face of the sliding block and their counterparts on the bottom of the magnet rotator, with the former matches with the latter from the top to bottom. In comparison with the prior art, the utility model is characterized by simple and rational structure, conveniences in use and assembly, enhanced whole-unit performance, etc.
