A sucker attachment device includes a support base, a pivot seat pivotally mounted on the support base, a sucker mounted on the pivot seat, a rotation disk swivelably mounted on the support base, and a receptacle assembly mounted on the rotation disk. The pivot seat has a spherical universal connector pivotally mounted on the support base. The support base has an end portion formed with a spherical pivot recess, and the universal connector is rotatably mounted in the pivot recess of the support base. Thus, when the support base is pivoted relative to the universal connector, the universal connector is rotated in the pivot recess through 360° so that the support base is pivoted relative to the pivot seat to change the angle and direction between the sucker and the receptacle assembly freely.
