Description

Technical Field

[0001] The utility model relates to the technical field of tool holders, in particular to a tool holder with hundreds of grids. Background Art

[0002] A grid knife, also known as a paint film scribing device, is primarily used to test the adhesion of coatings such as paints and varnishes. It primarily consists of a blade and a handle. The blade is typically composed of multiple hard blades, and the spacing between the blades can be adjusted to accommodate different testing requirements. The blade is generally made of high-hardness alloy steel to ensure it will not deform or damage during use. The handle is used to hold and operate the grid knife. The handle is typically made of plastic or rubber, offering excellent anti-slip properties and making it easier for the user to apply force. The method of use is as follows: Use the grid knife to scratch a certain size of squares on the surface of the coating, then apply tape or other specific tools to the scratched area, quickly tear off the tape, and observe the coating peeling. The coating's adhesion level is assessed based on the area and degree of coating peeling. The grid knife holder is a device for placing the grid knife.

[0003] Currently, after testing paint samples, the grid knife is directly stacked together with other tools. The blade part is easily bumped against other metal tools, thereby damaging the blade. Moreover, it is placed in a messy manner with other tools, making it difficult to find the grid knife when it is needed. Therefore, a grid knife rack is proposed. Utility Model Content

[0011] A further improvement of the technical solution of the present utility model is that: the surface of the second slide rail is slidably connected to the first sliding block, and the bottom of the first sliding block is fixedly connected to the hanging plate.
