Abstract: A utility cutter includes right and left covers that are screwed together to receive a blade braking gear and a spare blade cartridge therein. The blade braking gear includes a blade holder for holding a blade thereto, and a slide button and a blade-replacing key movably connected to the blade holder. When the slide button is depressed and slid forward, the blade-replacing key and the blade holder are moved forward to extend the blade; when the slide button is depressed and slid backward, the blade is retracted into the covers; and when the blade-replacing key is depressed when the blade is extended, the blade could be removed from the cutter and replaced with a new one. The spare blade cartridge stores multiple spare blades therein. By pushing a front cover of the cartridge forward, a spare blade is pushed out of the cartridge for replacing an old blade.

Abstract: The invention relates to the improved structure for an ink cup, particularly such structure having upper and lower cover bodies, a thread winding wheel, a manual turning wheel and an inverted T-shaped pressing disk. The interior of the inverted T pressing disk encloses a compression spring and is set inside the manual turning wheel by means of a hollow circular rod. The manual turning wheel cooperates with a circular hole in the upper cover body, and is urged into contact with the upper cover body by the compression spring in the pressing disk. A spiral spring in the thread winding wheel automatically rewinds the thread except when the manual turning wheel is squeezed against the cover body to stop the thread winding wheel.
