摘要:
A stepwise powerful suction device includes suction holders, suction elements, resilient elements, a support frame, and rotary knobs. The support frame and the three suction holders are integrally formed together. A portion of the support frame forms a handle. Each suction element forms an upright post extending through the respective resilient element and suction holder. Each suction holder forms a multi-step stepwise recess, and each rotary knob has a handgrip that forms a multi-step stepwise projection overlappingly engaging the multi-step stepwise recess and including a safety button, a spacer ring, and a bolt extending through the handgrip of the rotary knob to engage an inner-threaded hole defined in the respective suction element. Each suction holder forms a stop, and the handgrip of the respective rotary knob forms a counterpart raised portion.
