1. An angle grinder, comprising:
a housing;
an output shaft at least partially extending out of the housing and being rotatable relative to the housing about a first axis;
a sleeve fixedly connected to the housing, wherein the output shaft passes through the sleeve;
a first shield surrounding the output shaft and detachably connected to the sleeve, the first shield having a first end and a second end;
a second shield having a first end and a second end surrounding at least a part of the first shield and detachably connected to the first shield; and
a first connector mounted to an outer surface of the first end of the second shield and configured for connecting the first end of the second shield to the first end of the first shield,
a second connector mounted to an outer surface of the second end of the second shield and configured for connecting the second end of the second shield to the second end of the first shield,
wherein the second shield comprises a first elastic mounting element proximate a first opening defined in the first end of the second shield, and a second elastic mounting element proximate a second opening defined in the second end of the second shield, the first elastic mounting element cooperating with the first connector to detachably connect the first end of the second shield to the first end of the first shield, and the second elastic mounting element cooperating with the second connector to detachable connect the second end of the second shield to the second end of the first shield,
wherein the second shield further comprises a first connection port for connecting the first connector to the first elastic mounting element and the second shield further comprises a second connection port for connecting the second connector to the second elastic mounting element,
wherein each of the first connector and the second connector is a metal element,
wherein each of the elastic mounting elements at least partially protrudes from a curved surface and each of the elastic mounting elements inclines toward the first axis, and
