Further improvement as the utility model above-mentioned pair of rotation engines: the shift fork body that described selector fork assembly comprises Z-type and the handle be fixedly connected with it, shift fork body one end is connected with shifting block; Described shifting block is between high speed driving tooth and low speed driving tooth.
Further improvement as the utility model above-mentioned pair of rotation engines: described handle is L-type, and its vertical portion is fixedly connected with shift fork body, its horizontal component bends to input shaft direction.Namely save space, be convenient to again hand and grasp, meet body mechanics.
Further improvement as the utility model above-mentioned pair of rotation engines: described motive bent axle is provided with the annular groove that two are positioned at initiatively duplicate gear both sides, is connected with for spacing back-up ring in annular groove.Can prevent initiatively duplicate gear from offseting with power case lid or gear shift cover because displacement is excessive, produce wearing and tearing.
Further improvement as the utility model above-mentioned pair of rotation engines: the distance between described low-speed active gear and high speed driving gear is less than the distance between low speed driven gear and high speed driven gear.
Further improvement as the utility model above-mentioned pair of rotation engines: described high speed driven tooth is near power case lid, and low speed driven tooth is near gear shift cover.Because high speed driven tooth diameter is greater than low speed driven tooth, for the ease of installing, low speed driven tooth is near gear shift cover.
