A tool structure includes a tool having a rotation shaft formed with a central hole for insertion of the distal end of a tool. The rotation shaft is provided with a cover, and has an outer wall mounted with an elastic member and a drive member. A drive shaft is passed through a first guide slot of the rotation shaft and a second guide slot of the shaft seat in the rotation shaft. Multiple clamping shafts are mounted in the shaft seat to mate with a clamping recess formed in the rotation shaft. Thus, when the tool head is rotated by the rotation shaft, the tool head may be fixed rigidly and stably by the relative urging effect between the clamping recess and the clamping shafts during rotation of the rotation shaft.
