Abstract: The present invention discloses a dual color molding apparatus for a measuring tape and its molding method, and a dual color plastic technology is used to replace the existing label and decoration such as a label on the measuring tape and provide a different design of words, numbers or logos on a concave and convex surface to facilitate users to identify the molding apparatus. The molding apparatus includes a male mold fixing base, a first male mold, a second male mold, a female mold fixing base, a first female mold, a second female mold, a central axle and a middle plate. The first female mold forms a first cavity with any one of the male molds, and the second female mold forms a second cavity with any one of the male molds, and a glue injection is performed in the first cavity and the second cavity by a first glue injection unit and a second glue injection unit respectively.

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.
