摘要： A combined pad structure contains a disc base and a body. The disc base includes an anti-slid area defined on a bottom end thereof. The body includes a circular groove defined on a bottom end thereof to receive the disc base and includes a limiting portion formed on four corners of the bottom end thereof. Thereby, when the body is placed onto the disc base, the disc base is limited in the circular groove of the body, hence the body allows being rotated along the disc base. Also, when the body disengages from the disc base, they allow being used respectively, thus increasing using functions.

摘要： A dual-use knife for cutting a circle and a straight line has exchangeable circular blade upper covers to provide the function of cutting the circle or the straight line. The knife has quick release fasteners to be moved in guiding grooves of a handle so that thick and thin circular blade upper covers may be released from or fastened to a push-control member and an accommodating slot. Also, moving the push-control member in the groove can control the front circular blade to extend out for cutting or to be retracted so that the knife has two functions.
