Abstract

A power tool with a protective hood includes a shell (1), a bearing seat (2) arranged on the shell (1), an output shaft (4) with an axes line X, a protective hood (6) movably matched and connected with the bearing seat (2) and a locking device which locks the protective hood (6) relatively to the bearing seat (2); the locking device includes a locking piece arranged on the side wall (61) of the protective hood (6); the locking device further includes stop elements (20,30) arranged on the side wall (21) of the bearing seat (2); when the stop elements (20,30) are matched and connected with the locking piece, the protective hood (6) is locked relatively to the bearing seat (2). The invention simultaneously discloses a gear warning tone device which is suitable for generating cues when adjusting the protective hood.

Description

technical field [0001] The invention discloses a power tool with a shield, in particular to a sand grinding power tool. Background technique [0002] Power tools with guards typically include angle grinders, grinders, and the like. According to the needs of the work, grinding and cutting at certain special angles, or for operators who use the angle grinder with left hands, it is necessary to adjust the angular position of the guard so that the guard can be repositioned to to the protective effect. [0003] The traditional way of adjusting and positioning the shield is to unlock the shield relative to the fuselage, so that the shield can rotate freely, and then rotate the shield by a certain angle, and then lock the shield through a locking device. A common locking device is a cam locking mechanism, which is suitable for a power tool with a movable journal, that is, a cam is provided on the journal of the shield. After the shield is installed on the fuselage, the operator ...
