Claim 0:
1. An adjustable spinning arm for converting a rotational motion of a rotational shaft to a linear movement of a targeted object that comprises a revolving piece and a rod;
wherein a lower end of the rod is connected to the rotational shaft, and an upper end of the rod is axially connected to the revolving piece by a bearing;
wherein the revolving piece is connected to the rod in a way that the revolving piece is in a state of tilting aside in relation to the rod such that a revolving axis line of the revolving piece crosses a rotation axis line of the rod;
wherein the rotational shaft is designed to be connected to and to be rotated by a power source so that the rotational shaft can rotate the rod around its rotation axis; wherein the revolving piece is capable to move outwards and is designed to roll over and be in contact with the targeted object when the tilt of the revolving piece is from right to left with respect to a contact plane on the targeted object;
wherein when the revolving piece rolls over and be in contact with the targeted object in a first direction the revolving piece can exert upward force on it so that the targeted object can move upward, and when the revolving piece rolls over and be in contact with the targeted object in a second direction the revolving piece can exert downward force on it so that the targeted object can move downward.
