A tool including a buffer structure adapted to prevent shocks includes a tool head, a first shaft structure, and a second shaft structure. The tool head has a first connecting portion. The second shaft structure is attached to the slide and links with the tool head. The second shaft structure is movable with respect to the first shaft structure such that the tool head is moved toward and away from the first shaft structure. The second shaft structure has a second connecting portion receiving the pivot. The tool head is pivotal with respect to the second shaft structure. Further, a resilient member is disposed between the first and the second shaft structures. The second shaft structure is biased by the resilient member.
