  • Patent number: 11364605
    Abstract: A magnetic sleeve includes a body and a magnetic unit disposed in a second section of the body where a locking socket and a mounting hole are formed and communicating with each other. The mounting hole is enclosed by a peripheral wall while taking a reference point as center. The peripheral wall includes at least one engagement surface and at least one curved wall surface. Each engagement surface has two transition points for meeting the wall surface. The formation of one engagement surface or more engagement surfaces not only attains a firm engagement between the magnetic unit and the mounting hole but also forms a space therebetween to discharge air from the mounting hole smoothly, thereby preventing the magnetic unit from being broken during the installation. The space is also minimized to avoid undue accumulation of metal chips and allow the magnetic unit to be held in position stably.

  • Publication number: 20140060263
    Abstract: The present invention is provides a fitting assembly for a hand tool with enhanced snapping capability, operation smoothness, and reduced manufacturing cost. The fitting assembly contains a body and one end of the body has a fitting member. The fitting member has a radial through channel connecting two opposing sides of the fitting member. Two steel balls and a conical spring in between are housed in the through channel. By simultaneously compressing the both ends of the conical spring through the steel balls on the fitting member, and as the smaller rings of the conical spring are squeezed into the larger rings to effectively reduce the length of the compressed conical spring and to align the steel balls' engagement direction and the axial direction of the conical spring, the fitting assembly provides enhanced snapping capability, operation smoothness in connection and detachment, and reduced manufacturing cost of the hand tool.

  • Patent number: 8651764
    Abstract: A quick release extension rod with a positioning structure comprises a body, a return member, an inserting rod, an even number of balls, a positioning ring, a control ring assembly, four elastic members and a C-shaped retainer. The balls are disposed on the connecting head of the inserting rod, so that the radial interval between the socket and the connecting head of the base of the quick release extension rod can be evenly distributed. When the socket rotates, the arrangement of an even number of balls can reduce the possibility of the asymmetrical-center-of-gravity caused oscillation. The four elastic members are disposed between the control ring assembly and the body to push the socket can be abutted against the control ring assembly to delimitate the axial interval, which further stabilize the center of gravity of rotation of the socket while preventing the occurrence of oscillation of the socket.
