    Abstract: In a multi-function tool structure, a body and a work rod are pivotally connected together and can form a folded and retracted state. Moreover, an elastically movable press button is disposed on the body and can link up a positioning pin movably inserted into the work rod. Thus, pressing the press button can release a lock between the work rod and the positioning pin so that the work rod is swingable, while releasing the press button can lock the positioning pin and the work rod together again. Thus, the work rod and the body can be folded and retracted to facilitate the storage and carrying. After the work rod is developed, it can form multiple included angles with respect to the body so that the requirements of different operation angles can be satisfied.

  • Publication number: 20140033881
    Abstract: Disclosed is a spanner tool for mounting or dismounting components, which comprises a control piece (2), a connecting piece (1) and a rotating piece (3). The connecting piece (1) is hinged with one end of the control piece (2) and one end of the rotating piece (3) respectively. An angle ? formed between the control piece (2) and the connecting piece (1) is less than an angle ? formed between the rotating piece (3) and the connecting piece (1) when the control piece (2) and the rotating piece (3) respectively rotate to limit positions at different sides of the connecting piece (1). The spanner tool is practical and reliable. During use, a user does not need to swing his/her arm and only needs to rotate his/her wrist to operate the spanner tool, so the spanner tool is convenient and rapid-in-use. The spanner tool can be folded for portability when not in use. Additionally, locking tightness of the tool can be adjusted by adjusting a nut.

  • Patent number: 8539864
    Abstract: A dual-handled ratcheting socket wrench having a drive head and a pair of handles pivotably attached at opposite ends of the drive head, and a manually-withdrawable, quick-release pin extending through each handle and the drive head to form a hinge. The quick-release pin can be withdrawn manually from the aligned holes without the use of a hand tool. The dual-handled ratcheting socket wrench can have a locking mechanism for independently securing the handles at a variable pivot position relative to the drive head. The dual-handled socket wrench allows a mechanic to apply substantially equal, co-rotational force to each handle.

  • Patent number: 8511206
    Abstract: A ratchet wrench includes a body, a driving head, a control member and a resilient member. The body includes a handle and a Y-shaped extension. The driving head is pivotably connected to the Y-shaped extension by two pivots and an inner groove and a recess are respectively defined in the inside of the Y-shaped extension. The inner groove accommodates the C-shaped plate of the control member and the resilient member is received in the recess. The C-shaped plate has engaging teeth defined in distal ends thereof and the pivots each have ratchet teeth which are engaged with the engaging teeth by moving the control member so as to control the rotation of the driving head relative to the body.

    Abstract: A rotation control device for a tool is disposed between a handle and a tool head and includes two ratchet wheels, a spring and two C-shaped snap rings. The two ratchet wheels are symmetrically arranged. When pressed, the respective ratchet wheels will be subjected to the same force and move the same distance, thus making the engagement between the ratchet wheels and the tool head more assured, while avoiding the stuck fault and improving the convenience in use.
