  • Publication number: 20040040423
    Abstract: A drive device for a spiral screwdriver includes a barrel having a first end longitudinally and co-axially secured in a handle of the spiral screwdriver, and a second end formed with a distal flat. A polygonal hole is longitudinally defined in the barrel and extends to the distal flat of the barrel. An axle is movably and partially received in the polygonal hole, and has a polygonal cross-section corresponding to that of the polygonal hole. A locking member extends through the barrel and the axle in the barrel to selectively hold the axle in place. A chuck is selectively universally mounted to a free end of the axle and has a distal flat formed to selectively abut the distal flat on the barrel.

  • Publication number: 20030136692
    Abstract: A tool box has box which pivotally installed with a transparent cover. A hook extends from the cover toward the box. The box has a concave portion corresponding to the hook for being buckled by the hook. The box has a spacer. The spacer spaces the interior of the box into an upper receiving chamber and a lower receiving chamber. The lower receiving chamber has an opening penetrating the box at a side with respect to the concave portion. A disk is placed into the lower receiving chamber from the opening. The concave portion of the disk corresponding to the box has a stop plate. The thickness of the stop plate is smaller than the depth of the concave portion. Thereby, the hook of the cover buckles the concave portion and at the same time it resists against the stop plate for fixing the disk.

  • Patent number: 6401301
    Abstract: A screwdriver grip including a tool section, a connecting section and a grip. A front end of the tool section is disposed with a working section and a rear end of the tool section is formed with a pivot section pivotally connected with a pivot cavity of the connecting section, whereby the tool section can be pivotally rotated relative to the connecting section. The grip is back and forth sliably fitted on the connecting section. A locating member is disposed between the connecting section and the grip. When the grip is moved forward or rearward to a certain position, the locating member fixedly locates the grip on the connecting section. The grip can be moved rearward and the connecting section can be pivotally rotated by a certain angle for a user to easily hold the grip. Alternatively, the grip can be moved forward to shorten the length of the screwdriver.

  • Patent number: 6397708
    Abstract: A screwdriver grip including a front section and a rear section pivotally connected with the front section. The outer edge of the pivot section is formed with more than one inward recessed engaging section. The center of the front end of the rear section is formed with a pivot cavity. Two sides of the pivot cavity are respectively disposed with two lugs. When the pivot section is pivotally connected with the pivot cavity, the lugs of the rear section clamp the pivot section of the front section. The rear section is disposed with a projecting engaging block corresponding to the engaging section of the front section. When the in rear section is moved forward, the rear sections is engaged with the front section and located without pivotally rotating. When the rear section is moved backward, the front section and the rear section can be pivotally rotated by a certain angle for a user to hold.

  • Patent number: 6389626
    Abstract: A Tool structure including a tool assembly and two grips. The tool assembly is formed by a first, a second, a third and a fourth arms which are pivotally connected with each other to form a mechanism as a four-link mechanism. The first and second arms and the third and fourth arms respectively form two kinds of tools. Two ends of the grips are respectively pivotally connected with the pivot sections of the first and third connecting sections and the pivot sections of the second and fourth connecting sections. Therefore, when the grips are held and closed to make the tools formed by the first and second arms and the third and fourth arms get close to each other and close, the two grips are not coaxially pivotally rotatable with the first and second arms and the third and fourth arms. Accordingly, the maximum opening extent of the two grips can be reduced for easy holding.

  • Patent number: 6336383
    Abstract: A wrench structure including a main body, a pivot block pivotally connected with the main body, a projecting block pivotally connected with the pivot block and a grip pivotally connected with the projecting block. A first engaging mechanism is provided between the pivot block and the main body. A locating unit is disposed between the projecting block and the pivot block. A second engaging mechanism is disposed between the grip and the pivot block. The first engaging mechanism serves to control the main body to be engaged with the pivot block and located at different angles from the pivot block. The locating unit serves to control the projecting block to engage with or disengage from pivot block to be free to rotate. After the grip is pivotally rotated to contain different angles with the pivot block, the second engaging mechanism serves to locate and fix the grip with the pivot block.

  • Patent number: 6145995
    Abstract: A precision screwdriver includes a hollow grip and a bottom cap screwed with a bottom end of the grip. An end face of the bottom cap is disposed with a central switch and a conducting member. A rotary cover is rotatably disposed at the end face of the bottom cap. A cell is received in the grip. A light shade is installed in a non-circular socket of front end of the grip. A bulb is disposed in the light shade. An engaging seat of a transparent sleeve is engaged in the non-circular socket. The front end of the sleeve is formed with a tool connecting section for engaging with a screwdriver head. The switch is received in the rotary cover, so that a user can push the end face of the rotary cover at the end of the grip with fingers or palm so as to rotate the precision screwdriver. Via the switch, the user is able to control the on/off of the bulb in the grip so as to provide an illumination for the work.
