Abstract
An electric-powered cutting machine includes: an electric motor, a housing for the electric motor; a plunger driven by the electric motor to reciprocate; and a blade holding mechanism. The blade holding mechanism holds a blade at a tip end portion of the plunger. The blade holding mechanism includes: a blade receiving face including a groove, a swinging member and a pressing member. The groove is shaped substantially the same as an attachment portion of the blade. The swinging member has one and other ends and pivoted at a swing fulcrum. The one end has a blade pressing portion capable of being disposed to oppose to the groove. The other end elongates to separate from the plunger. The pressing member presses the one end toward the groove.
