Abstract: A driving rod assembly includes a rod having an insertion section for coupling with a rotating head of a power tool and an operative section for coupling with an external tool. The rod further includes an outer periphery having first and second positioning grooves and a positioning portion between the first and second positioning grooves. The operative section includes a coupling portion located in front of the second positioning groove and having a stopper edge wider than the positioning portion. A coupling end is provided at a front end of the operative section. A C-clip is mounted on the positioning portion of the rod. A jacket includes a receiving section slideably mounted around the positioning portion. The jacket further includes a coupling section located mounted around the coupling portion of the rod to rotate together with the rod. The receiving section includes a coupling groove for receiving the C-clip.

Abstract: A ratchet wrench includes a ratchet wheel received in a handle and having an insertion hole. The ratchet wheel further includes an outer periphery having a toothed portion and a lower section below the toothed portion. The lower section includes an annular engagement groove and a cutout intercommunicating the annular engagement groove with the insertion hole. A clip includes a notch and has a diameter slightly smaller than a spacing between upper and lower wall faces of the annular engagement groove and larger than a depth of the annular engagement groove. The clip is not on the same plane when placed flat. The maximum width between an upper edge and a lower edge of the clip is slightly larger than the spacing between the upper and lower wall faces of the annular engagement groove. The clip includes an engagement section received in the cutout and extending into the insertion hole.

Abstract: A toolbox includes a space for receiving tools and includes a peripheral side and top and bottom sides. The peripheral side includes at least one snap fastener on an upper end thereof and at least one engagement portion on a lower end thereof. The at least one snap fastener includes a flexible engagement plate. A hook is formed on an upper end of the engagement plate. The lower end of the engagement plate can be pressed to move the hook away from the peripheral side of the toolbox. The hook of the at least one snap fastener of the toolbox can engage with at least one engagement portion of another similarly constructed toolbox stacked above the toolbox. The at least one engagement portion of the toolbox can engage with a hook of at least one snap fastener of another similarly constructed toolbox stacked below the toolbox.

Abstract: A method for producing a drill bit includes preparing a metal shank and a metal drill, with the metal shank having a hardness greater than a hardness of the metal drill. Each of the metal shank and a metal drill includes an end having an end face. The metal shank and the metal drill are connected end to end, with the end face of the metal shank coaxially abutting the end face of the metal drill. The ends of the metal shank and the metal drill connected end to end are welded to form a molten pool at the welding area. A surface treatment is conducted on the welding area after welding. The welding area is annealed after the surface treatment.

Abstract: A toolbox includes a receiving seat having two sidewalls. Each sidewall includes a first guiding groove and a pivot. A pivotal seat receiving tools is received in the receiving seat and includes two sides. Each side of the pivotal seat includes an axle received in one of the first guiding grooves and a pivot coupling portion coupled with one of the pivots. A pressing seat includes two vertical portions respectively mounted to the sidewalls of the receiving seat. Each vertical portion includes a second guiding groove. Each axle is received in one of the second guiding grooves. An elastic element is provided for returning the pressing seat. When the pressing seat is pressed, the second guiding grooves of the pressing seat press against and move the axles along the first guiding grooves, the pivot coupling portions couple with the pivots, and the pivotal seat pivots to an exposed position.
