[0034] Working principle:

[0035] The slotted sheets to be installed are installed between each separator 10. Slotted sheets with different intervals can be set according to different needs, and the threaded hole 2 of the mounting shaft 1 is installed on the output end of the angle grinder and is threadedly connected to the output end. When the limiting part 3 is tightened, the limiting part 3 contacts the separator 10 and the slotted sheet on the output end of the angle grinder to complete the fixation. When the angle grinder reciprocates, the set convex part 5 can rotate in the opposite direction, so that the mounting shaft 1 can be buffered, thereby achieving a stable structure of the mounting shaft 1 that is not easy to be damaged.

[0036] Embodiment 2:

[0037] This embodiment provides a modification head for a slotted blade of an angle grinder, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features.

[0038] A hexagonal nut 12 is formed on one end surface of the limiting portion 3 .

[0039] The integral hexagonal nut 12 can make the limiting part 3 more convenient to screw.

[0040] A hexagon socket hole 13 is formed in the abutment nut 9 .

[0041] The hexagon socket 13 has six contact surfaces, which can transmit torque more effectively than traditional screw heads. This allows greater force to be applied when tightening or removing, thereby reducing the possibility of slipping or sliding; the hexagonal shape makes it easier and more accurate to insert and fix the tool in the hexagonal hole. This design helps prevent the tool from slipping or slipping during operation. This is particularly important for occasions that require high precision and fine operation; because the hexagonal head provides more contact surfaces, compared with traditional screw heads of similar size, they distribute force more evenly when tightening, thereby reducing wear on the tool and the screw head itself; the hexagonal socket head design can accommodate more screw driving functions while reducing the external space requirements relative to the hexagonal bolt head. This makes them more convenient to install and remove in limited spaces.

[0042] The mounting shaft 1 is made of stainless steel.

[0043] When the angle grinder is working, water needs to be added to cool it down. The mounting shaft 1 is made of stainless steel to prevent rust from forming between the mounting shaft 1 and the separator 10. They are fixed together and are not easy to disassemble.

[0044] A second plane symmetrical to the first plane 6 is provided on the side wall of the mounting shaft 1 .

[0045] A second plane may be provided, or a plurality of other planes evenly distributed around the circumference may be provided, so that the stability of the structure can be enhanced by the number of planes.

[0046] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which belong to the protection scope of the present application.
