Pull-type shift transmission system and food processor

Abstract

The invention relates to a pull type transmission system, which comprises a pull mechanism. The pull mechanism at least comprises a coaxial column, the coaxial column is formed by connecting rotary discs with different diameters, and planes connecting the rotary discs with different diameters are connecting faces. The pull mechanism is provided with a rope tying position, the rope tying position is arranged on a side face of the pull mechanism, and the pull rope is connected to the pull mechanism through the rope tying position at one end and is wound around the rotary discs. The pull mechanism is connected to a resilience mechanism and is used for retracting the pull rope after the pull rope is pulled out. The invention provides a non-electric pull type transmission system. The corresponding rotating gears can be changed through simple up-down pulling actions without having to shut down and replace equipment or interrupt the pulling operation, making the use more convenient.
