Abstract
A multiple-angle transmission tool includes a first shell, a transmission stick, a first gear, a second shell, a connecting unit, a second gear, a transmission unit and a screw bolt, wherein each the first shell and the second shell has a connecting surface that has a number of recessed portions arranged in a circular manner, and each recessed portion is spaced with a protruding portion to form a restricted position to engage. Also, the first gear, the second gear and the transmission unit are located in a receiving space formed within the first shell and the second shell. When the first shell and the second shell move along the entire circumference, the momentum can be transmitted and changed when the first shell, the second shell and the transmission unit are engaged.
