At the same time, hang the inner wall of the limiting hole 20 in the silica gel block 19 on the outer wall of the hanging bolt 7 for simple limiting. Then slide up the protective cover 4, so that after the magnetic attraction blocks one 8 on both sides are close to the magnetic attraction blocks two 12, a magnetic attraction effect is generated, so that the top of the protective cover 4 fits against the bottom of the top plate 2, realizing the limitation of the protective cover 4. When the blade 10 is exposed to the environment, it can be used. When not in use, drag the protective cover 4 down from the bottom of the top plate 2, then remove the silica gel block 19 from the outside of the hanging bolt 7, and then reinsert the rubber plug 11 into the inner wall of the protective cover 4, so as to produce a sealing protection effect on the outside of the blade 10, reduce the contact with moisture or dust in the air, avoid oxidation and erosion, and improve the service life. When it is necessary to remove the blade 10 for grinding, just lift the cover 6 again, and then pull the concave plates 9 on both sides of the tool holder 1, so that the springs 15 on both sides are stretched, and at the same time, the relative ends of the plug bolts 14 are detached from the jacks 17, and then the limitation on the plug-in blocks 16 is released, and the plug-in blocks 16 can be detached from the slots 18, realizing the convenient disassembly of the blade 10 for grinding and maintenance.
