20150290781 | STRAP WRENCH - A strap wrench is used to drive a cylindrical object and contains: a handle including two recesses and a longitudinal slot; a strap including a first end portion and a second end portion which are inserted into the two recesses; a guiding rod longitudinally inserted into the handle; a supporting block rotatably connected with a first segment and located inside the strap; a movable member disposed on the guiding rod and moving between a first position and a second position, the movable member joining with the strap; a push switch slidably fixed in the longitudinal slot and rotatably connected with the movable member; and a spring for pushing the movable member to move toward the second position. Thereby, the movable member is driven by the engaging block to move between the first position and the second position so as to operate the strap wrench easily. | 10-15-2015 |
20140059824 | Universal Ball Joint Extractor - A universal ball joint extractor has a first body having a first applying end for engaging with a ball joint. A second body has a second applying end for pushing against a member having the ball joint. A connecting rod connects the second body and the first body to allow relative movements thereof. A control screw for pushing an rear end of the second body and an rear end the first body provides an opposite force to the first applying end to push out the ball joint. | 03-06-2014 |
20120186056 | UNIVERSAL CLUTCH ALIGNMENT TOOL - An universal clutch alignment tool is provided. A tool rod is assembled with a connecting mechanism, and the connecting mechanism is then assembled with a positioning pipe, thereby forming a tool for assembling/disassembling a clutch. The connecting mechanism includes a sleeve, a driving rod, and connecting blocks. The sleeve is made into a hollow pipe in which a driving head at one end of the driving rod is disposed. The surface of the sleeve is formed with slots respectively arranged at an angular interval in which the connecting blocks are received. The outer surface of the driving head is formed with a conical driving slope. The middle section of each driving block is provided with a V-shaped notch. The inner walls on both sides of the notch are formed with two connecting slopes symmetrical to each other. The outer edge of the driving head is inserted into the notches of the connecting blocks, so that the tool rod drives the connecting blocks via the driving rod to generate a radial expansion or retraction, thereby allowing various kinds of clutches to be assembled or disassembled. | 07-26-2012 |
