[0018] In order to clearly illustrate the technical features of the present patent, the present patent will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.
[0019] The present invention is as Figure 1-2 As shown, it includes a box body 1, an input shaft 2, a driving gear, an output shaft 3 and a sector gear 4. The input shaft 2 and the output shaft 3 are parallel, and both are connected to the box body 1 through bearings. The gear is fixedly connected to the part of the input shaft 2 that extends into the box body 1 through a synchronous rotating mechanism such as a square key and spline, and the sector gear 4 is fixedly connected to the output shaft 3 through a synchronous rotating mechanism such as a square key and spline. In the part inside the body 1, the driving gear and the sector gear 4 mesh with each other when the angular stroke valve is actuated.
[0020] In actual use, a fixed connection or other struct...
