Problems solved by technology

However, the blade is very easy to wear and tear. After drawing a limited number of times, the blade will be damaged and blunt, and the entire blade needs to be replaced, which is costly
In addition, the direction of the cutting edge is determined after the cutting head is processed. For some film tests that require the angle of the cutting edge, the hundred grid knife is no longer applicable, and its versatility is poor.

Abstract

The invention relates to a pen type cutter. The pen type cutter comprises a cutter handle with a containing cavity and a plurality of blades contained in the containing cavity, and an opening is formed in the end of the cutter handle. The pen type cutter further comprises a plurality of gaskets contained in the containing cavity, and the multiple gaskets and the multiple blades are arranged alternatively and are fixedly locked into the containing cavity in a detachable manner. By means of the pen type cutter, the lineation efficiency can be effectively improved, and the using cost can be lower.

Description

technical field [0001] The invention relates to a pen-type tool, in particular to a pen-type tool for testing the film layer on the surface of a workpiece. Background technique [0002] At present, in order to evaluate the adhesion of the film layer after the surface of the workpiece is treated (such as spraying or coating), according to the standard ISO2409-2007, it is necessary to use a blade to vertically draw one hundred pieces with an area of ​​about one square millimeter on the surface of the film layer. square grid (also known as a hundred grid), and use a brush to remove surface debris. Then, use a special adhesive tape to stick it on the grid, pull up the tape quickly after a period of time, and observe the peeling off of the film layer in the area of ​​the grid under a magnifying glass, so as to judge the adhesion degree of the film layer to the substrate. [0003] In the prior art, in order to realize the drawing of a hundred grids, one way is to use a hundred gr...
