The invention discloses a stepless speed change foot pedal for a ceramic throwing machine. The stepless speed change foot pedal comprises a bottom plate, a supporting seat fixedly connected to the bottom plate, a pedal seat, a pedal fixedly connected to the upper surface of the pedal seat, a transmission gear fixedly connected with the pedal seat and a speed changer in transmission connection with the transmission gear. When the foot pedal is treaded, the foot pedal drives the transmission gear to rotate, the transmission gear drives a driven gear to rotate, the driven gear drives the speed changer connected with a motor of the ceramic throwing machine to rotate, and therefore the speed change function is achieved. The stepless speed change foot pedal is simple in structure and convenient to use, and the stepless speed change function can be achieved without arranging a speed change mechanism in the ceramic throwing machine. The structure of clamping locating rods through clamping blocks is adopted for the pedal seat and the transmission gear, the pedal and the transmission gear are connected and limited, the transmission gear is immediately driven to rotate when the pedal moves, the structure is simple, and implementation is easy.
