Abstract: A device and a method for automatically categorizing screwdriver bits are provided. The method includes three main steps: accommodating and mixing, vibration feeding, and type categorizing. The device includes a device body and a vibrating feeding cylinder disposed on the device body. The vibrating feeding cylinder includes a rotating holder for vibrating and moving the screwdriver bits and a directional mechanism for arranging the driving tips of the screwdriver bits facing the same direction. A CCD mechanism is disposed on the device body and is used to detect the shape of the driving tips of the screwdriver bits.

Abstract: A machine for making screwdriver bit sockets includes a feeing unit and a rotary unit located beside the feeding unit. The rotary unit includes a feeding area, a put-in area, a pressing area and a ready area. The rotary unit includes a disk rotatably connected to a base. Multiple holding units are connected to the disk and moved to one of the feeding area, the put-in area, the pressing area and the ready area when the disk rotates. A feeding arm is located beside the pick-up area and the feeding area to move the sockets from the pick-up area to the holding units. A pressing unit located above the pressing area to press a screwdriver to a socket. A pick-up arm picks up the sockets from the holding units. A control unit electrically controls the rotary unit, the feeding arm, the pressing unit and the pick-up arm.

Abstract: A tool bit hanger includes a hanging member and at least two holding members detachably connected to one another in series. The hanging member is provided with a lateral hole by means of which the tool-bit hanger is able to be hung from a user's belt. Each of the holding members is formed in one piece of resilient synthetic resinous material, and includes a male end portion at a top thereof and a female end portion at a bottom thereof and a pair of lateral receptacles for reception of tool bits. In particular, the male end portion of one of the holding members is detachably engaged in the female end portion of the other holding member to lock the two holding members together.

Abstract: A hand tool with bit release device includes a connecting shaft, a block, a positioning bead and a cover. When the user wants to insert a tool bit into the connecting shaft, the user pushes the tool bit into the connecting shaft directly and the positioning bead engages with the tool bit firmly. When the user wants to release the tool bit from the connecting shaft, the user moves the cover axially relative to the connecting shaft and the positioning bead disengages with the tool bit so that the tool bit is released from the connecting shaft.

Abstract: A tool box includes a box body having a top cover and a bottom cover which are pivoting on each other, two foldable sets which are both assembled to the top cover and the bottom cover, at least one positioning base is assembled between the two foldable sets. Under this arrangement, the positioning base can be rotated outward relative to the bottom cover by the operation of the two foldable sets. Therefore, the user can pull out the tool bit from the positioning base directly without bending up the tool bit by the finger thereof at first.

Abstract: A tool box includes a box formed by top and bottom covers, in which the two covers are pivoted with each other so that the box can open or close; a lock member, in which one end of the lock member is pivoted on the bottom cover and another end of the lock member is used to lock with the top cover; and two handles disposed on top and bottom covers respectively. If the box is unlocking, the handle on the bottom cover is blocked by the lock member and the handle is not allowed to be bent up. Consequently, a user will be aware that the box is unlocking.

Abstract: A rotary tool includes a tool body having a driving end formed thereon and an annular groove defined therein. An indicating coiled spring is received in the annular groove. The indicating coiled spring has a colored indicating mark formed thereon for easily identifying a standard of the rotary tool. The indicating coiled spring is made of metal, wherein the indicating coiled spring is hard to be broken and a lifetime of the indicating coiled spring is lengthened. The indicating coiled spring is able to elastically expand to be easily and co-axially sleeved on the annular groove of the tool body, such that the indicating coiled spring being replaceable and re-useable. When operating, the indicating coiled spring is rotatable relative to the tool body.

Abstract: A tool box structure includes a plurality of row sockets. Each row socket has a plurality of insert holes defined therein for adapting to receive a screwdriver bit and a positioning gutter formed at the bottom thereof. A box body is pivotally connecting to the row sockets. The box body has a plurality of positioning slots defined therein and corresponding to the quantity of the row sockets in the box body. An elastic element is installed between each positioning slot and each positioning gutter. The positioning slot and the positioning gutter is abutted by two ends of each elastic element. A cover body is installed to the box body. A plurality of openings is defined in the cover body and respectively corresponding to the insert holes in the row sockets.
