  • Patent number: 6263768
    Abstract: A ratchet tool includes a toothed inner periphery defined in the ring-shaped head and a rotatable member is engaged with the toothed inner periphery. A recess is defined in a surface of the head and a driving member is rotatably received in the recess. A notch is defined in a side defining the recess and communicates between the recess and a central hole in the head. An elongated protrusion extends from the rotatable member and a disk is securely mounted to the protrusion. The driving member is rotatably engaged with the disk so that when rotating the driving member, the rotatable member is able to be rotated at a small angle.

  • Patent number: 6205891
    Abstract: A ratchet wrench includes a ring-shaped head having a threaded inner periphery and an operation member is rotatably retained in the head. The operation member has a ridge member extending from one end thereof and two pawl members are respectively retained on two sides of the ridge member. Each pawl member has a first side with teeth defined therein and a second side of each pawl member includes two inclined surfaces on two end of the second side and a straight surface is connected between the two inclined surfaces. The teeth of each pawl member are engageable with the threaded inner periphery of the head. One of the two inclined surfaces and the straight surface of each pawl member is engaged with respective one of the two parallel surfaces of the ridge member. An operation disk is mounted to the head and two torsion springs are respectively connected between the two pawl members and the operation disk.

  • Patent number: 6176161
    Abstract: A damaged screw removing screwdriver includes a handle and a shank extending from the handle. The shank has a distal end for being engaged with slots in the head of a bolt. A plurality of blade portions extend radially outward from the distal end of the shank and each blade portion has a cutting edge and a corner. The handle has a plate attached to the distal end thereof so that the blade portions cut into the material of the head of the bolt by impacting the plate on the handle. By the screwdriver, the bolt having rounded slots in the head can still be rotated.

  • Patent number: 6145412
    Abstract: A ratchet tool includes a head and a shank extending from the head in which a ratchet and a pawl are received in the head. A rod is rotatably inserted in the the shank and a grip is connected to the distal end of the shank. The grip is detachably connected to the first end of the rod, and an actuating member is connected to the second end of the rod. The actuating member is engaged with the ratchet which is rotated by the actuating member by rotating the grip. Therefore, the ratchet together with a bit or a socket connected to the ratchet are rotated simply by rotating the grip.

  • Patent number: 5761973
    Abstract: A double-headed wrench assembly includes an upper pressing member with a first driving head and a lower pressing member with a second driving head mounted on upperside and underside of a wrench body respectively. An upper thrust rod has an upper portion slidably mounted in the first driving head and a lower portion with a first enlarged head. A lower thrust rod has a lower portion slidably mounted in the second driving head and an upper portion with a second enlarged head abutting on the first enlarged head. A first biasing member is urged between a lower portion of the upper pressing member and the first enlarged head and a second biasing member is urged between an upper portion of the lower pressing member and the second enlarged head. A first ball is slidably retained in a first detent recess defined in the first driving head and is detachably received in a first cavity defined the upper thrust rod.
