<p>A structure for a suction cup comprises a suction cup shell (1), a suction control lever (2) and a hard-PVC suction cup (5); the suction control lever (2) is connected to a spring inside the suction cup shell (1) by means of a pivot shaft (3); the spring is fixedly connected to the hard-PVC suction cup (5) and a connection piece (4) is fixedly connected to the lower portion of the suction cup shell (1). The present suction cup is able to adhere to sheet glass, to uneven tiles and to smooth surfaces, and is able to prevent slippage due to air leakage attributable to an unequal distribution of force.</p> |
