ABSTRACT:
A pen-shaped spectacles repair kit includes a pen-shaped body having a two-sectioned case and a cap, and a screwdriver. A rear inner end of the case opposite to the cap is formed into a space for holding some spare parts for spectacles; the screwdriver has a middle body having two blades projected from two ends thereof. The screwdriver is fitted in the case by inserting the middle body into a fixing hole provided at a front end of the case, so that the screwdriver turns when the case is turned. The cap closed to the front end of the case completely covers the projected blade, and a clip provided on the cap allows the pen-shaped spectacles repair kit to be clamped on a user's pocket and conveniently portable for tightening screws on the spectacles at any place and any time.
