Description

Technical Field

[0001] This utility model relates to the field of rechargeable angle grinder technology, and in particular to a rechargeable angle grinder. Background Technology

[0002] Rechargeable angle grinders are portable power tools powered by rechargeable lithium batteries and equipped with high-speed motors to drive grinding and cutting consumables. Their core feature is freedom from power cords, making them key equipment in metal, stone, and wood processing scenarios due to their cordless portability and multi-functional capabilities. Essentially, they use a high-speed rotating motor to drive different types of consumables to achieve various processing needs such as cutting, grinding, rust removal, and polishing, catering to both light-duty home use and heavy-duty industrial applications. In existing rechargeable angle grinders, the battery needs to be removed before and after each charge. Removing the battery multiple times will inevitably cause it to loosen and make poor contact. In addition, the grinding handle of some rechargeable angle grinders is fixed, which can be inconvenient for the dominant hand when changing angles. Therefore, there is a need to propose a rechargeable angle grinder. Utility Model Content
