Guided by the bit shaft assembly, the bit tip may rotate relative to the bit shaft assembly and change the tip without requiring direct manual contact with the bit tip. Particularly, the screwdriver includes a handle, a bit tip, a shaft and a shaft sleeve. The bit tip includes two sizes/styles of tips at two ends respectively. The bit tip is pivotably coupled to the shaft. The shaft is fixedly coupled to the handle. The shaft sleeve surrounds the shaft. The shaft and shaft sleeve are slidingly coupled together. Outwards sliding of the shaft sleeve drives the bit tip to rotate within the shaft to achieve bit-changing. A deep groove is formed on a front end of the shaft. The bit tip is disposed in the deep groove. A middle section of the shaft has a guide groove. The shaft sleeve is connected to the guide groove by a connecting element disposed along the guide groove. A slide guide block is fixedly positioned on the shaft sleeve facing a side of the shaft having the deep groove. The shaft sleeve has a notch. The notch is formed in a middle section of the shaft sleeve. A spring element is connected to the shaft sleeve. The spring element moves within the notch. The automatic bit-changing screwdriver provides a solution to a technical problem that the state of the art combination screwdrivers are generally inconvenient to change bits. | 10-02-2014 |
