Abstract
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.

A tool structure for clamping a tool head quickly, comprising:
- a tool having a rotation shaft having a center formed with a central hole so that a distal end of a tool head may be inserted into the central hole, wherein:
- the rotation shaft has a top provided with a cover, and has an outer wall mounted with an elastic member and a drive member, and the drive member is urged by the elastic member, a drive shaft is fixed in the drive member and in turn extended through the rotation shaft and a shaft seat, the rotation shaft is provided with a first guide slot for passage of the drive shaft, and the shaft seat is provided with a second guide slot for passage of the drive shaft, the second guide slot has a slope different from that of the first guide slot, such that the rotation shaft and the shaft seat have different opposite positions when the drive member and the drive shaft are operated, multiple clamping shafts are mounted in the shaft seat to mate with a clamping recess formed in the rotation shaft.
