20160089807 | CUTTING TOOL - A cutting tool includes a pipe, a pressing foot assembly, a spring, and a blade assembly. The pressing foot assembly is slidably sheathed on an end of the pipe. The spring is sheathed on the pipe. An end of the spring abuts against the pipe, and the other end of the spring abuts against the pressing foot assembly. The blade assembly passes through the pipe and the pressing foot assembly in a slidable manner. When the cutting tool moves along a first direction, the pressing foot assembly keeps pressing against an object in a second direction substantially perpendicular to the first direction, such that the blade assembly protrudes from the pressing foot assembly and cuts the object along the first direction. | 03-31-2016 |
