  • Publication number: 20160303715
    Abstract: The present disclosure illustrates an improved structure of a wrench having a swingable ratchet. In this improved structure, a head portion of a main body includes a through hole to contain a driving member, a cover of a block ring is used to restrict the driving member to stay within the through hole, and a connector of the driving member is abutted against an inner rim of the via hole of the cover by a periphery thereof, so as to restrict a bias swing angle of the driving member in a width direction of the head portion, and block teeth of the detent member can be fully engaged with the ratchet without being departed from the ratchet.

  • Patent number: 8857296
    Abstract: In a ratchet wrench body and its manufacturing method, the body comprises a handle and a head, and the head has a through hole, a control compartment, and a slot chamber. The head has a first surface and a second surface, and at least one embedded hole formed between the slot chamber and the first and second surfaces, and each embedded hole is penetrated through one side but not penetrated through the other side, and each embedded hole is smaller than an elastic element and a propping element contained in the slot chamber, and the slot chamber is extended from each embedded hole inwardly towards the slot chamber and formed by the total volume occupied by adjacent intersected surfaces.

  • Patent number: 8800410
    Abstract: A ratchet wrench with a direction switching structure includes a wrench body with an axial slot, a control slot, and a pivot slot which are interconnected, and a ratchet wheel, a ratcheting member, and a switching member are installed therein, respectively. The switching member pushes against the ratcheting member through a prop member and selectively controls the engagement between the ratcheting member and the ratchet wheel. The circumferential wall of the pivot slot has a circular slot and a stepped surface formed at a position near an opening of the pivot slot provided for latching the switching member into the circular slot by a latch portion thereon and being stopped by the stepped surface for the positioning purpose. The prop member pushes against an appropriate position of the ratcheting member to prevent an unsecured engagement between the ratcheting member and the ratchet wheel.

  • Patent number: 7444904
    Abstract: A ratchet mechanism for a ratchet tool includes a pawl received in a recess of the head and biased by a bead which is biased by a spring received in a notch defined in an inner periphery of the recess. The pawl has a toothed surface which is matched with outer threaded surface of a driving wheel which is rotatably received in a through hole of the head. A receiving hole is defined through the pawl and opens a top surface of the pawl. A peripheral groove is defined radially outward in an inner periphery of the receiving hole. A shift member has a top board and a rod which extends from an underside of the top board, a stop is connected to a distal end of the rod. The stop and the rod are inserted into the receiving hole and the stop is movably engaged with the peripheral groove.

  • Patent number: 6283606
    Abstract: A ratchet wrench with illuminating device, including two clamping boards, a pad block, a rotary member and at least one cell cover. By means of the pad block sandwiched between the clamping boards, the ratchet wrench can be easily manufactured and applied to those situations necessitating great torque and working sites with insufficient illumination. Therefore, the ratchet wrench is more competitive on market. When it is necessary to replace the cell, a user only needs to push the cell cover in a specific direction so as to open or close the cell cover. Therefore, the cell can be easily replaced.
