摘要： The present embodiment discloses a hand-held tool and a clamping device thereof. The clamping device of a hand-held tool includes: a mounting base; a clamping unit configured to fasten a working tool in an axial direction; and an operation assembly, including an operating member and a driving member, where the operating member is capable of performing compound motion relative to the mounting base, and the operating member is operable to drive the driving member to selectively mate with and disengage from the clamping unit. In this way, the hand-held tool of the present embodiment has the clamping device. By way of compound motion, not only comfort of operation can be achieved, but also parts can be saved, thereby making the structure simpler and more reliable.
