ABSTRACT:
A vacuum suction apparatus with adjustment lever is disclosed. The structure of the vacuum suction apparatus includes a suction cup and a wheel base, which has a receptacle being attached by the suction cup from underneath, a semi-circular cogwheel being fixed on top of the receptacle, and an adjustment lever pivotally connected through an opening. The adjustment lever has a pinion on the bottom end, where the gearing of the pinion is to fit against corresponding gearing on the vertically erected rack at the center when the lever is in locked position. The upper portion of the lever also has a suction lock/release that allows the user to manually adjust the angle of the lever by pegging onto scooped cogwheel with a slider, so the suction strength can be adjusted desirably for continuously holding onto the same spot in extended use.
