081450000 | Inserted portion mounted to pivot or swivel relative to longitudinal axis of handle | 6 |
20100000381 | Driver with tail - [PROBLEMS] Entire body of a driver is composed of a material which can be sterilized by an autoclave or an ultrasonic cleaner; when the driver is used in a limited space such as in a body cavity, work can be carried out efficiently without causing any trouble with a rotary work, and aspiration aberrant entry can be prevented when the driver body is dropped by mistake; ; and amount of rotation, rotation angle or rotary torque can be recognized even at the molar tooth portion. | 01-07-2010 |
20100154604 | Tool with Adjustable Working Angle - A tool with adjustable working angle is provided with a first rod and a second rod which are pivoted to both ends of a connecting member, so the two rods are able to swing with respect to the connecting member. Furthermore, the swing direction of the connecting member with respect to the first rod is the same as the swing direction of the connecting member with respect to the second rod. Hence, through the pivotal motion between the connecting member and the first and second rods, the wrench of the present invention can be adjusted at different working angles so as to adapt to different working environments. | 06-24-2010 |
20120103146 | HIGH TORQUE SCREWDRIVER - The application discloses a screwdriver that is movable from a first position to a second position. In the first position, the drive shank of the screwdriver is positioned parallel with the elongate handle. In the second position, the drive shank of the screwdriver is positioned perpendicular to the elongate handle, and is selected when additional torque must be applied to the drive shank. Structure of the screwdriver provides enhanced stability for the drive shank supported by the handle. | 05-03-2012 |
20140060266 | Hexagonal Wrench - A hexagonal wrench includes a driving member and an actuating member. The driving member includes a hexagonal driving section for driving a bolt having a hexagonal socket. The driving member further includes a pivotal section pivotably connected with the actuating member, allowing relative pivotal movement between the driving member and the actuating member during operation. An area of the driving member is smaller than an area of the driving section to provide enhanced structural strength, preventing deformation and damage of the hexagonal wrench while providing reliable connection between the driving member and the actuating member. | 03-06-2014 |
20140174265 | Holding Wrench with Torsion-Resistant Variable Engagement Mechanisms - The holding wrench consists of a torsion-resistant lever with an extension for a pivot to hold a second torsion-resistant arm to present two mobile surfaces in a fixed work plane. The force of the present invention is applied parallel to the work plane resulting in a torque vector that is perpendicular to the work plane. The working ends of the lever and arm have emplacements for tooling such as rigid pins or holes to attach to protrusions such as bolt heads. Two male tooling emplacements each consist of hole in which tooling is inserted and a threaded hole located orthogonal to the tooling hole for a set screw or other fastener that may hold the tooling in place. Two female tooling emplacements may be used to directly engage protrusions on a sprocket or as receptacles for tooling custom fitted to said protrusions. | 06-26-2014 |
20150306750 | SCREW TIGHTENING TOOL - A screw tightening tool includes a case body, a tool member, and a switching portion. The case body includes a guide portion configured such that a head portion of a screw is inserted therein. The tool member includes an engaging portion including a bit portion configured to engage with the head portion. The switching portion supports the tool member. The switching portion is configured to switch a position of the tool member among a first positon, a second position, and a third position. The first position is a position in which the bit portion protrudes to an outside from the case body. The second position is a position in which the bit portion protrudes to the outside from the case body and that is different from the first position. The third position is a position in which the case body houses the bit portion. | 10-29-2015 |
