Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of angle grinders, in particular to a protective device for angle grinders. Background Art
[0002] An angle grinder is a grinding tool used for cutting and grinding fiberglass. Since some debris will be splashed during grinding, a protective structure will be installed on the outside of the grinding section of the angle grinder to block and protect the debris splashed during the grinding process of the grinding section, protecting the user's hands from being splashed by debris.
[0003] However, there are still some shortcomings in the actual use of angle grinders. The most obvious ones are:
[0004] 1. Currently, a protective cover is installed outside the grinding section of the angle grinder. However, the protective cover is a fixed structure and the position of the protective cover cannot be adjusted according to the actual grinding needs, resulting in omission of the sputtering area without the protective cover, and thus being unable to adapt to different grinding and cutting needs.
[0005] 2. Currently, when workers use angle grinders, they need to hold the angle grinder with both hands. Holding it with one hand may cause loss of grip due to the high speed of the grinding slice, resulting in an irreversible situation. However, the current angle grinder lacks a position for holding it with both hands, which makes it inconvenient to use. Utility Model Content
