  • HAND TOOL WITH A HANDLE
    Publication number: 20140290449
    Abstract: A hand tool includes a handle, a press member, a shank body and multiple latch assemblies. The handle is formed with a receiving cavity and a locating hole in communication with the receiving cavity. The press member is movably disposed in the locating hole. The shank body is fitted in the receiving cavity and movable relative to the handle. The shank body is formed with multiple sockets. The latch assemblies are respectively mounted in the sockets. When the shank body is moved, (for example, slid or rotated) relative to the handle to make one of the sockets aligned with the locating hole, the latch assembly latches the shank body with the handle. When pressing the press member, the latch assembly unlatches the shank body from the handle, the shank body is movable relative to the handle.

  • THREADED MEMBER CAPABLE OF DETECTING TENSION
    Publication number: 20140283617
    Abstract: A threaded member has an axial direction. A thread is formed on the threaded member in the axial direction. At least one receiving recess is formed on a circumferential surface of the thread of the threaded member. At least one sensor member is disposed in the receiving recess for detecting tension applied to the threaded member in the axial direction. When a tightened article is tightened by the threaded member, an extension force/tension is applied to the threaded member in the axial direction. The sensor member is positioned in adjacency to the thread of the threaded member so that the sensor member can precisely detect the extension extent of the threaded member for precisely obtaining the tightening force applied to the threaded member.

  • THREADED MEMBER CAPABLE OF DETECTING TENSION
    Publication number: 20140260652
    Abstract: A threaded member capable of detecting tension includes a sensor component. A receiving space is formed in the threaded member. The sensor component has a flexible member and a sensor. The sensor is disposed on the flexible member. The sensor component is disposed in the receiving space of the threaded member and preset in a compressed/flexed state in an axial/longitudinal direction of the threaded member. When an article is tightened with the threaded member, the threaded member is tensioned to change the flexion of the flexible member. At this time, the sensor can detect and find the tension of the threaded member to achieve the tightening force applied to the threaded member.
