ABSTRACT:
A securing device for securing a blade of a cutting tool includes a clamp assembly, a bolt, a resistant slice and a driving member. The clamp assembly has two clamp members between which the blade is clamped. The bolt extends into the clamp assembly and is screwed into a driving shaft device of the cutting tool for securing and pressing the clamp assembly to clamp the blade. The resistant slice is shaped to a curvature. The bolt is through the resistant slice, and the head of the bolt presses the resistant slice so as to force the clamp assembly. The driving member includes a body fixed on the head of the bolt and a handle pivotally coupled to the body. The distance between the head of the bolt and a movable end of the handle is changed when the handle pivots with regard to the body.
