A handheld pneumatic grinder comprises a main body, a transmission portion, and a wheel guard structure. The main body defines an active space. The transmission portion is provided on the main body. The wheel guard structure includes a coupling member, a protective hood, and a control member. The coupling member is coupled to the main body around the transmission portion. The protective hood is rotatably mounted to the coupling member at a center thereof, wherein the protective hood is provided with an engagement means defining a plurality of indentations. The control member has a protrusion, which can engage with one of the indentations of the engagement means to allow the protective hood to be fixed in an angle position. The present invention allows the protective hood to be adjusted without using an external tool, and can achieve a compact design. |
