Abstract: A tool box includes a housing defining a front opening, a rear opening and an accommodation chamber in communication with the front opening and the rear opening to open to the outside; a swing seat pivotally mounted in the housing within the accommodation chamber and providing a storage rack at the bottom side, multiple insertion slots at the top side and a retaining block, a first baffle plate mounted in the housing at a front side relative to the storage rack, a second baffle plate mounted in the housing at a rear side relative to the insertion slots, a push-button, the swing seat to be biased relative to the housing to an access position when the user pushes a push-button.

Abstract: A tool bit adapter having a position-limit rod includes a base member including a cylindrical body defining a longitudinal receiving open chamber and radial through holes and a ball movably mounted in each radial through hole, an operating member, a first elastic member stopped between a retaining ring at the cylindrical body and the operating member, a pusher having a position-limit groove located in the periphery thereof, a position-limit rod mounted in the cylindrical body and projecting into the receiving open chamber and inserted into the position-limit groove and selectively stoppable at one of two opposite ends of the position-limit groove, a second elastic member stopped between the pusher and the cylindrical body, and one or multiple locating grooves formed in the pusher or a tool bit to be installed for receiving the balls.

Abstract: A tool bit adapter includes a base member including a cylindrical body having a receiving open chamber formed of a front small diameter portion, a rear large diameter portion and one or multiple through holes in communication between the small diameter portion and the atmosphere, a ball mounted in each through hole, an operating member slidably sleeved onto the cylindrical body and having an inside groove and a pressure face, a pusher accommodated in the cylindrical body and having one or multiple recessed retaining portions. When the pusher is in the rear end position, the pressure face of the operating member forces the balls toward the inside of the receiving open chamber into engagement with the respective recessed retaining portions. Thus, the tool bit adapter can positively detachably secure the loaded tool bit without any additional positioning structure.

Abstract: A screwdriver includes a grip defining an accommodation chamber, an inner tube with interference holes mounted in the accommodation chamber, a rod member movable in and out of the inner tube and having interference grooves corresponding to the interference holes and a neck and carrying a latching member, an operating device set, which includes an operating member rotatably mounted at the front side of the grip, interference members and an actuation member having a pressure wall for holding down the interference members, a first elastic member, a ring cap having an axial hole and a stop wall around the axial hole for stopping the latching member, and a second elastic member. Thus, the screwdriver is operable by rotating the operating member and effectively prevents the rod member from being ejected out of the grip.

Abstract: A rotary toolbox includes a box body defining a first opening and a second opening, a hollow shaft mounted in the box body in communication with the first opening and having a third opening on the periphery, a locking member having a first protruding rod inserted through the third opening, a compression spring stopped against the locking member, a tool tray having a through hole pivotally coupled to the hollow shaft and a first locating groove disposed in the through hole and providing a carrier portion, a spiral spring connected between the box body and the tool tray. After pressing the locking member to move the first protruding rod out of the locating groove, the spiral spring will bias the tool tray to carry the carrier portion to the second opening for allowing the user to store tool parts or to pick up storage tool parts.
