Abstract: A tool storage box with sliding and rotating functions includes a box body, a sliding base, and a tray for tool head portions. The box body has a space for the sliding base and the tray. The sliding base controls sliding of the tray in the space. The sliding base is provided with a pivotal shaft and a locking hook for controlling the sliding base. The pivotal hole has a pivotal trough. A peripheral surface of the pivotal trough has a positioning surface. The tray has a pivotal shaft and a positioning post for controlling rotation of the tray. The pivotal shaft engages with the pivotal hole of the sliding base to act as a center of rotation of the tray. When the tray slides out of the box body, the positioning post engages with the pivotal trough, and the tray is rotatable by means of an external force.

Abstract: A screwdriver includes a main body, an end cap, and a holding seat. Thus, the tips are inserted into the mounting holes of the holding seat and received in the receiving chamber of the main body, thereby facilitating the user carrying the tips, and thereby saving the space of storage. In addition, the holding seat is rotatable relative to the end cap, so that the mounting holes of the holding seat are directed outward to facilitate the user removing or placing the tips.

Abstract: A screwdriver includes a main body, an end cap, a holding seat, and a release mechanism. Thus, the holding seat and the end cap are removed from the main body easily and rapidly, thereby facilitating the user taking or placing the tips mounted in the mounting holes of the holding seat. In addition, the user only needs to press the push button of each of the two push button sets of the release mechanism so as to detach the holding seat and the end cap from the main body, thereby facilitating the user removing the holding seat and the end cap from the main body.
