Abstract
A hand-held belt sander includes a head, an arm, a retaining unit, and a positioning unit. The head includes a mounting seat surrounding an axis. The arm has a sleeve segment mounted to the mounting seat. The retaining unit has an annular groove formed in the mounting seat, and multiple protrusions disposed on the sleeve segment and engaging the annular groove. The positioning unit includes multiple engaging grooves formed in the mounting seat, and an engaging member disposed on the sleeve segment. When the engaging member engages one of the engaging grooves, the arm is positioned relative to the head at an operating position. When the engaging member is disengaged from the one of the engaging grooves, the arm is rotatable about the axis relative to the head.
