The present invention provides a screw holder suitable for a driver bit which has a long or short length and is selectively exchanged depending on the working purpose in a manual driver or an electric driver. The screw holder has a pole shape. In addition, linear or cruciform tips for applying screwing force of a screw are provided at both ends of the screw holder. Mounting grooves for being detachably coupled with a driver body are formed inside the tips. The screw holder includes: a stator detachably installed at one end of the driver bit by using the mount grooves through an elastic support element, and a mover moving backwards and forwards while riding on the stationary element and including grasping elements for elastically supporting a pillar of the screw mounted on the tips of the driver bit. Therefore, convenient installation can be achieved by using the simple elastic support element. Further, the screw can be stably grasped, thereby improving the screwing workability. |
