20130042727 | SCREWDRIVER BIT - A screwdriver bit has a shank, a connecting portion, a necking portion defined between the shank and the connecting portion, a head disposed on a distal end of the connecting portion, multiple ribs separately arranged around the connecting portion and the necking portion and multiple shear grooves respectively defined between the connecting portion and the necking portion and each shear groove is defined between two adjacent ribs. When a torsion force is applied to the screwdriver bit, a shear force formed between the necking portion and the connecting portion is concentrated on points where the ribs and the shear grooves connect with each other in a dot-like form. Therefore, the screwdriver bit has strengthened shear strength and prolonged life for use. | 02-21-2013 |
20130042728 | SCREWDRIVER BIT - A screwdriver bit has a shank, a connecting portion axially protruding from the shank and a head axially protruding from the connecting portion. A stress dispersion recess is formed in an end surface of the shank. The stress dispersion recess disperses a residual stress present in the screwdriver bit. Therefore, the screwdriver has strengthened structure, good durability and prolonged life for use. | 02-21-2013 |
20130042729 | HANDLE FOR A HAND TOOL - A handle for a hand tool includes a body, a guider, and a movable assembly. The body has a chamber, a connecting portion, and an opening. The chamber is defined in the body. The connecting portion is defined in the body for assembling a tool bit. The opening is defined in the body and communicating with the chamber. The guider is inserted into the chamber. The guider has a spindle, a first positioner, a second positioner, and multiple guiding fins. The movable assembly includes a clamping seat movably received in the chamber and a puller mounted on the clamping seat. The clamping seat has a through hole, a shoulder, and multiple clamping units. The through hole is defined through the clamping seat for receiving the guider. | 02-21-2013 |
20130043154 | CONTAINER FOR TOOL BITS - A container for tool bits includes a casing, multiple bit seats pivotally connected with the casing, and a hanger connected with the casing. The casing has a back plate, a bottom plate extending from the bottom of the back plate and being perpendicular to the back plate, multiple partition plates extending from the back plate and being respectively perpendicular to the back plate and the bottom plate and multiple cavities respectively defined between the partition plates. Each cavity has two first buckles extending form two inner sides of the cavity. The bit seats are respectively mounted in the cavities, and each bit seat has two second buckles formed on two sides of the bit seat. The hanger has a through hole defined through the hanger. | 02-21-2013 |
20130043201 | HAND TOOL DISPLAY BOX - The hand tool display box has a bracket and multiple storing mounts. The bracket has multiple mounting recesses and a hanging panel. The mounting recesses are formed in the bracket and each mounting recess has two first locking parts. The hanging panel is connected to a top edge of the bracket and has a hanging hole to facilitate hanging the display box on a display rack. The storing mounts are connected pivotally to the bracket and each storing mount covers a corresponding mounting recess and has two second locking parts and a clamping part. The second locking parts engage the first locking parts of the corresponding mounting recess. The clamping part is used for holding a hand tool. Therefore, the multiple storing mounts can hold different kinds of hand tools and users can conveniently take out a needed hand tool by opening one storing mount relative to the bracket. | 02-21-2013 |
