发明名称 Telescopic hand tool
摘要 A telescopic hand tool includes a hollow drive shaft that extends from a handle member and that has a distal bit-retaining end portion. A telescopic shaft is disposed within the drive shaft, and has a distal end section retractable into and extendible outwardly from the distal bit-retaining end portion of the drive shaft. A connecting member is mounted securely on the distal end section of the telescopic shaft so as to be retractable therewith into the drive shaft. The connecting member includes a tubular body having an external screw thread and an end face formed with a receiving hole, and a magnet disposed securely in the receiving hole. A tool accessory has a coupling portion formed with a cavity for capping on the connecting member. The cavity is confined by an internally threaded surrounding wall for connecting threadedly with the external screw thread of the connecting member.
