Description

Technical Field

[0001] The utility model relates to the technical field of lithium-electric angle grinders, in particular to a lithium-electric angle grinder which is convenient for replacing grinding discs. Background Art

[0002] An electric angle grinder, also known as an electric angle grinder, is an electric tool for grinding. Because the axis of the grinding wheel is at right angles to the axis of the motor, it is particularly suitable for situations where the position is restricted and ordinary grinders cannot be used. An electric angle grinder is a grinding tool used for cutting and grinding fiberglass. The machine can be equipped with a variety of working heads, such as coarse grinding wheels, fine grinding wheels, polishing wheels, rubber wheels, cutting wheels and wire wheels. An electric angle grinder uses high-speed rotating thin-blade grinding wheels, rubber grinding wheels, wire wheels, etc. to grind, cut, rust remove and polish metal components.

[0003] When an existing angle grinder is performing cutting work, a worker needs to apply force to the angle grinder so that the grinding wheel of the angle grinder extends into the workpiece for cutting, and at the same time, the force must be controlled to avoid contact between other components and the workpiece. Therefore, cutting is laborious and inconvenient. At the same time, when a straight line is cut on the workpiece, deviation is likely to occur, resulting in the workpiece being scrapped.

[0004] A brushless lithium electric angle grinder is proposed in the patent document with the publication number CN217776574U. The device includes a machine body, two sets of mounting frames are arranged under the machine body, each set of mounting frames has two mounting frames, the inner wall of each mounting frame is rotatably connected with a guide wheel, a connecting plate A is fixedly connected between the outer walls of each set of two mounting frames, a connecting plate B is fixedly connected between the outer walls of the two connecting plates A, a connecting plate C is fixedly connected to the outer wall of the connecting plate B, a positioning plate is fixedly connected to the top of the connecting plate C, a positioning groove is provided on the outer wall of the machine body, and the positioning plate is slidably connected to the inside of the positioning groove. When cutting, the construction personnel only need to apply force downward to make the four guide wheels contact the surface of the workpiece. By supporting the machine body with the guide wheels, other components except the grinding wheel can be effectively prevented from contacting the workpiece. Therefore, the construction personnel do not need to deliberately control the force to prevent other components from contacting the workpiece, which is more convenient to use.

[0005] However, when the device is working, sparks are likely to fly everywhere, making the device dangerous.

[0006] For this reason, we urgently need to provide a lithium-electric angle grinder that is easy to replace the grinding disc. Utility Model Content
