Spring operating mechanism and rack thereof

The invention relates to a spring operating mechanism and a rack thereof. The frame of the spring operating mechanism comprises a front vertical plate, a middle vertical plate and a rear vertical plate, wherein the three vertical plates are sheet metal parts and are arranged in a split manner, a supporting and connecting structure is arranged among the vertical plates, and the three vertical plates are assembled and fixed through the supporting and connecting structure. The front vertical plate, the middle vertical plate and the rear vertical plate of the rack of the spring operating mechanismare all made of sheet metal parts, standard parts and machining parts are saved, the machining process is simple, the consistency of the size is high, and the spring operating mechanism and the rackthereof are suitable for mass production and manufacture. Besides, the three vertical plates are arranged in a split manner, the supporting and connecting structure is arranged among the vertical plates, the three vertical pla
