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 connection receiving a pivot. The first shaft structure includes a slide. The second shaft structure is disposed on the slide and links with the tool head. The second shaft structure is movable on the slide such that the tool head is moved toward and away from the first shaft structure. The second shaft structure has a second connection 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.
