20110147683 | PULLER WITH ADJUSTABLE HOOK HEAD - A puller with an adjustable hook head comprises a hook head including an axial rotating extension rotably disposed on one end thereof, and including a plurality of toothed engaging recesses continuously arranged around an arcuate outer periphery thereof; a plate assembly including a first plate part and a second plate part, the first and the second plate parts including two connection ends disposed on one sides thereof respectively and being folded together to form a closed cavity, and the cavity including an aperture secured therein; a controlling member received in the cavity and including a driving block fixed on a top end thereof, including a retaining projection disposed on one side thereof in response to the engaging recesses of the hook head. | 06-23-2011 |
20110219846 | BIDIRECTIONAL PIPE BENDING PLIERS - A pair of bidirectional pipe bending pliers comprises: a first handle and a second handle. The first handle includes a first handle portion and a first pipe-bending portion, and the second handle includes a second handle portion and a second pipe-bending portion. When the first and second pipe-bending portions are closed toward each other to carry out clamping operation, the first and third bending grooves will define a first pipe-bending path therebetween, while the second and fourth bending grooves will also define a second pipe-bending path, the first and second pipe-bending paths extend in different axial directions. | 09-15-2011 |
20120151729 | REMOVAL AND REPLACEMENT TOOL FOR VEHICLES - A removal and replacement tool for vehicles contains a first body including a chamber, a second hole, and a third hole; a grip set including a second body and a push piece, the push piece including an arcuate notch; at least one first returning spring, one end of which is fixed in the chamber, and another end of which abuts against two sides of the second body; a shaft member disposed in the chamber, and its one end extending out of the first body from the first hole; a second spring, one end of which abuts against the chamber, another end of which is biased against the shaft member; an engaging member including a first side wall and a second side wall; a rotary knob including a rotating portion and a rod portion connecting with the rotating portion. | 06-21-2012 |
20120180607 | AXIAL CONNECTING STRUCTURE OF PLIERS - An axial connecting structure of pliers contains two symmetrical bodies axially connected together by using a first screw bolt and a nut; each body including a first extension with a grip and a second extension axially connected with a clamping paw, wherein the second extension includes a hollow fitting member, the fitting member includes a central hole, a limiting shaft, a positioning orifice to receive a spring and a ball, and a circular disc; the clamping paw includes an annular tab having a central post, the post includes an axial aperture, the tab also includes a receiving chamber to fit the fitting member and an inner fringe, the receiving chamber includes a guiding groove based on a radian of a predetermined degree of first central angle, the inner fringe includes plural recesses arranged thereon based on a radian of a second central angle. | 07-19-2012 |
20120291597 | TOOL FOR REMOVING LUG NUTS - A tool for removing lug nuts contains a supporting post including an actuating portion and two guiding portions extending outward from two sides of the actuating portion respectively; a screw rod including a head end and a circular extension extending outward from the head end, wherein an outer diameter of the head end is more than that of the circular extension, the circular extension includes a first and a second thread sections; two retaining arm, each including a hole to insert the guiding portion, an aperture arranged on a top end thereof to communicate with the hole, and an orifice secured thereon below the hexagonal hole and having a third and a fourth thread sections to screw with the first and the second thread sections respectively so that after the screw rod is rotated, the retaining arms are driven to close to each other or leave away from each other. | 11-22-2012 |
20130032007 | WRENCH - A wrench includes a transmitting device and a shell. The transmitting device comprises a rotor, a first working member, a second working member, a first linking member and a second linking member. The first linking member is disposed between the first working member and the rotor. The shell has a containing room for the linking device to be disposed therein. The shell comprises a middle section. The first end of the middle section extends upwardly to connect with the first section. The second end of the middle section extends downwardly to connect with the second section. Thus, the wrench has two stair portions of different horizontal level. And Users can hold the wrench more stably. Because the wrench uses the rotor and two linking members to drive the first working member and the second working member rotating, a total size of the wrench can be kept as smaller as possible. | 02-07-2013 |
20130097830 | OIL SEAL REMOVING TOOL - The present invention provides an oil seal removing tool including a pivotable hooking element and a location portion. The location portion has a slidable structure and an elastic element pressing against the slidable structure. The slidable structure is able to be engaged to the hooking element, and the elastic element pushes the slidable structure toward the hooking element. Moving the slidable structure can fix or release the engagement between the slidable structure and the hooking element. Thus, adjusting the working angle can be much easier and more efficient. | 04-25-2013 |
