  • Patent number: 7661638
    Abstract: A suction cup structure includes a suction cup, a lifting rod, a holder base, a slide bolt, a radial arm and an axial-bolt. The lifting rod is vertically connected to the suction cup, and has a through hole with horizontal penetration. The sleeve of the holder base has a rotation axis hole with horizontal penetration and a slide notch. The lifting rod is disposed in a sleeve of the holder base. The suction cup is under a disk body of the holder base. The slide bolt passes through a first hole of the button arm, the slide notch and the through hole. The axial-bolt also passes through the rotation axis hole and a second hole of the button arm. By pressing a button end of the button arm, an activation piece of the button arm rotates based on the axial-bolt to pull the slide bolt. The slide bolt then slides toward the upper portion from the lower portion of the first hole, and slides into the slide notch simultaneously to lift the lifting rod. The suction cup is therefore lifted to generate the suction.
