20120144960 | Hand Tool With An Adjustable Tool Head - A hand tool includes a tool head with an insertion hingedly connected to a pair of lugs of a handle to be rotatable relative thereto, and retained to an angular position by means of a spring-biased ball. The insertion is configured to have a hemispherical segment which includes front and rear segment strips extending circumferentially from an apical area that has a retaining concavity. Each segment strips has a plurality of circumferentially extending retaining grooves. The hemispherical segment further includes left and right cutout surfaces parallel and opposite to each other. By virtue of the hemispherical segment, rotation of the tool head relative to the handle and engagement of the ball in a selected one of the grooves and concavity are smooth and successful. | 06-14-2012 |
20120325060 | ANGULARLY ACCESSIBLE HEAD ASSEMBLY FOR A TORQUE HAND TOOL - An angularly accessible head assembly for a torque hand tool includes a drive shank and a head rotatably disposed on a coupling shell about drive and driven axes that intersect with each other by an angle of at least 90 degrees. First, second and third force transmitting members are disposed to couple the drive shank and the head by means of four joint subassemblies, each having a socket wall surface and an orientable portion matingly engaged with each other. A torque exerted upon the drive shank is transmitted to the head through the force transmitting members and the joint subassemblies so as to activate a rotational movement of a threaded connector. | 12-27-2012 |
20130081231 | TELESCOPIC HAND TOOL - A telescopic hand tool includes a main shank connected to a tool head at one end and inserted into an outer sleeve for gripping by a user. The outer sleeve has an inner surface including a first arcuate region extending along a circumferential line, and a second arcuate region displaced from the first arcuate region, disposed radially outward of the circumferential line, and having low and increased friction areas. A block attachment is disposed on the other end of the main shank, and has an engaging segment engageable interferingly with the increased friction area to prevent rotation of the outer sleeve relative to the main shank. | 04-04-2013 |
20130160618 | TELESCOPIC HANDLE FOR A HAND TOOL - A telescopic handle for a hand tool includes a main shank connected to a tool head at a distal end and insertable into an outer sleeve which a user grips. The main shank has a plurality of axially spaced retained regions such that a radially movable retaining member is engageable with a selected one of the retained regions. A key-and-keyway mechanism is disposed to guide axial movement of the outer sleeve and to guard against rotation of the outer sleeve relative to the main shank so as to permit delivery of an appropriate torque to the main shank. An operating member is disposed on and movable axially relative to the outer sleeve to radially move the retaining member. | 06-27-2013 |
20130228051 | TELESCOPIC HAND TOOL - A telescopic hand tool includes an outer tube, an inner rod and a positioning unit. The outer tube has an inner surface formed with opposite first and second grooves. The inner rod is inserted in and movable relative to the outer tube between retracted and extended positions, and has an outer surface that has a segment confronting the inner surface and formed with a furrow portion. The positioning unit is disposed in the outer tube and includes a positioning block corresponding in position to the furrow portion and a resilient member disposed in the furrow portion for biasing the positioning block toward the inner surface to engage releasably the first and second grooves. | 09-05-2013 |

20140102266 | TOOL HANDLE - A tool handle includes a first handle unit, a joint unit connected rotatably to the first handle unit and formed with a plurality of positioning grooves, a second handle unit connected co-rotatably to the joint unit, and a latch member inserted into the first handle unit and movable between a lock state, where two latching projections of the latch member engage two of the positioning grooves and the first and second handle units are non-rotatable relative to each other, and an unlock state, where the latching projections are disengaged from the two of the positioning grooves and the second handle unit is rotatable about the engaging block to permit adjustment of an orientation of the second handle unit relative to the first handle unit. | 04-17-2014 |
20140202289 | FLEXIBLE TOOL ROD DEVICE - A flexible tool rod device includes an inner rod unit and a sleeve pipe unit. The inner rod unit includes a drive head, a tool head opposite to the drive head, and a flexible connecting member interconnecting the drive and tool heads. The sleeve pipe unit is made of rigid material and includes a first sleeve pipe and a second sleeve pipe. The first sleeve pipe has a first end portion connected fixedly to one of the drive and tool heads. The second sleeve pipe is telescopically connected to the first sleeve pipe, and is movable relative to the first sleeve pipe between a covered position for providing rigidity to the flexible tool rod device, and an uncovered position to allow resilient deformation of the connecting member. | 07-24-2014 |
20140283654 | RATCHET DEVICE - A ratchet device includes a body, a ratchet wheel unit, and a switching unit. The body has an outer peripheral surface, at least one slide slot formed in the outer peripheral surface, at least one first groove, and at least one second groove. The ratchet wheel unit includes a ratchet wheel sleeved on the body, at least one first pawl member inserted into the first groove, at least one second pawl member inserted into the second groove, and resilient members biasing the first and second pawl members to engage the ratchet wheel. The switching unit is sleeved on the body, and includes a pushing member disposed in the slide slot, and a switching member connected to the pushing member. Through operation of the switching member, the first or second pawl member can be separated from the ratchet wheel. | 09-25-2014 |
20140360319 | HAND TOOL - A hand tool includes a tubular casing, a tubular member connected to the tubular casing, a rod body extending through the tubular member into the tubular casing, two collar assemblies surrounded respectively by two oppositely-extending frustoconical urging surface portions of the tubular member and surrounding the rod body, and two resilient members biasing respectively the collar assemblies to abut against the rod body and abut respectively against the urging surface portions to thereby restrain the rod body from moving relative to the tubular casing. When the collar assemblies are moved to be released from the rod body and the urging surface portions, the rod body is permitted to move relative to the tubular casing. | 12-11-2014 |
