Description

Technical Field

[0001] The utility model relates to the technical field of angle grinders, in particular to a lithium-electric angle grinder with a dust cover. Background Art

[0002] An angle grinder, also known as an angle grinder, is a handheld power tool used for cutting and grinding. For safety, angle grinders are factory-fitted with a protective shield. This shield is a semi-shield structure, meaning the inner side of the shield, near the grinder, is a protective baffle, while the outer side is open.

[0003] The protective cover of most angle grinders is fixed and installed by a clamp. It is used to cover the outside of the blade of the angle grinder, which plays a role in safety protection during the operation of the angle grinder and effectively avoids flying chips during the grinding and cutting process. However, for angle grinders with auxiliary handles, the installation position of the auxiliary handle is different and the installation position of the protective cover needs to be adjusted accordingly to effectively protect the hand holding the auxiliary handle. The traditional protective cover is fixed by a clamp, which is inconvenient to disassemble and adjust. Utility Model Content
