An outward biasing means is provided by way of a spring within a telescopic arm to keep the endless belt in tension. | 04-30-2009 |
20100197208 | Power-Driven Hand Tool With Clamping Fixture For A Tool - A power-driven hand tool is disclosed comprising a housing, a work spindle for driving a tool, which tool can be located between a tool end of the work spindle and a fixing mechanism, further comprising a displacing mechanism with a clamping lever, adapted to pivot about a pivot axis for displacing the fixing mechanism between a releasing position, in which the fixing mechanism can be released from the work spindle, and a clamping position in which the fixing mechanism is clamped on the work spindle by a spring. An impeding mechanism is provided that interacts with the clamping lever for impeding the pivoting movement of the clamping lever between the releasing position and the clamping position. | 08-05-2010 |
20110014855 | ADAPTER FOR ABRASIVE CUTTING WHEELS - An abrasive disc assembly for a tool having an externally threaded, motor-driven spindle. The assembly includes an abrasive disc having a central bore formed therethrough and a male portion having an internally-threaded hub portion and a flange portion. The outer dimension of the hub portion is sized to be received within the central bore and the internally-threaded hub portion is enmeshingly engagable with the externally threaded, motor-driven spindle. The assembly further comprises an articulating locking finger extending from the male portion and having a retaining surface. The articulating locking finger is deflectable between a locked position and a deflected position. Finally, the assembly includes a female portion having a central cavity and an engagement surface. The central cavity receives the hub portion of the male portion such that the retaining surface of the articulating locking finger engages the engagement surface thereby releasably coupling the male portion to the female portion and retaining the abrasive disc therebetween. | 01-20-2011 |
20110021119 | GRINDING WHEEL ASSEMBLY - The present invention discloses a grinding wheel assembly including a coupling member, two clamping disks and a grinding wheel. There is a plurality of bulged anchor rims around the coupling member. On both sides of the coupling member, there are two hollow ducts which are linked through a first shaft duct in the center and surrounded by a plurality of laterally penetrated ventilation openings. Two clamping disks are symmetrically mounted onto the grinding wheel. On one side of each clamping disk are anchor troughs, ventilation holes, cylinders and shaft ducts, and on the other side is a polygonal trough. There are cogs around the grinding wheel and there are clamping troughs and a plurality of mounting troughs on each side of the grinding wheel. In the center of the grinding wheel is a coupling opening whose inner wall has a plurality of concaved anchor openings. From above interrelated mechanical design, it tends to make the coupling member, two clamping disks and the grinding wheel tightly anchor with each other, so that the object of being installed or uninstalled easily, being steadily structured and being used for longer life time can be achieved. | 01-27-2011 |
20110076927 | POWER TOOL HOLDING ARTICLE - A power tool holding article is provided and fastened to a power output element by clamping. The power output element has a fastening portion which has at least one protrusive fastening element to hold the holding article. The holding article has an article body and a mating portion connecting to the article body. The mating portion has a plurality of bulged elements spaced from each other to form a plurality of holding spaces. The protrusive fastening element of the fastening portion is engaged with the holding spaces to hold the holding article. Thus no special-shaped drilling openings are needed on the holding article. It can mate power output elements made by varying producers to reduce cost and improve compatibility. | 03-31-2011 |
20110086582 | MOUNTING DEVICE FOR DISK-SHAPED ROTATING TOOL - An annular retaining groove is formed on the inner circumferential portion of the disk-shaped rotating tool, and a ringlike cushioning member is fitted in this annular retaining groove so as to be partially exposed. Both sides of the inner circumferential portion of the disk-shaped rotating tool are held by first and second holding members through the annular cushioning member. An axial portion of the first holding member is engaged with an output shaft of an electric rotary machine so that the disk-shaped rotating tool is rotated through the first holding member by the output shaft. | 04-14-2011 |
20110195642 | POWER TOOL PACKING APPARATUS - A power tool packing apparatus provides a packing force to form a compact coupling between an application tool and an output shaft of a power tool. The packing apparatus comprises a pressing disk, a crank set, a movable wheel and a plurality of steel balls. The movable wheel and the pressing disk form a space between them to hold the steel balls. The crank set has a plurality of pins butting the steel balls. The pressing disk has a force applying surface butted by the steel balls in regular conditions so that the pressing disk provides a packing force butted outward in the regular conditions. The movable wheel has retraction notches. When the movable wheel is turned, the steel balls slide into the retraction notches to provide the pressing disk an inward retraction space, thereby the packing force is released and the application tool can be disassembled quickly. | 08-11-2011 |
20120171938 | POWER TOOL - The present invention provides a power tool in which the permanent set of an elastic member is suppressed and the vibration reduction effect is maintained over a long period of time. A rubber ring is disposed as the elastic member between a wheel washer mounted on a spindle and a substrate of a diamond wheel, and these are secured by a locknut screwed to a tip of the spindle. This rubber ring absorbs the vibrations applied to the diamond wheel at grinding work. A mounting hole of the substrate is mounted on a boss portion of the wheel washer with a clearance fit, and spring pins whose both ends are supported by the wheel washer and a portion of a holding plate in the locknut are inserted into insertion holes of the substrate and insertion holes of the rubber ring with a clearance fit. | 07-05-2012 |
20120214388 | Position adjustment mechanism of grinding wheels - A position adjustment mechanism for grinding wheels includes a rotating body, a first grinding unit, a second grinding unit, and a fixing nut. The rotating body includes a fixing surface and a first thread portion. The first grinding unit includes a first grinding portion and a fixing portion fixedly engaged with the fixing surface. The second grinding unit includes a second thread portion, which is threadedly engaged with the first thread portion of the rotating body, and a second grinding portion which is spaced from the first grinding portion and which has a different grinding precision from that of the first grinding portion. The fixing nut is threadedly engaged with the first thread portion, and presses axially against the second grinding unit. Thereby, a rough grinding and a fine grinding can be accomplished together within a grinding process, and adjustment on a spacing between the two grinding wheels becomes easy. | 08-23-2012 |
