RATCHET WRENCH
A ratchet wrench includes a ratchet wheel made of metal and having a ratchet teeth section and a driving section. A pawl made of metal engages with the ratchet teeth section and is controlled by a switch to control the rotation direction of the ratchet wheel. A plate made of metal includes a coupling portion to which the ratchet wheel is coupled. The coupling portion includes a first through-hole through which the ratchet wheel extends. The pawl presses against an inner periphery of the first through-hole. The inner periphery of the first through-hole has a length in an axial direction smaller than a thickness of the ratchet teeth section. A stopper made of plastic material is mounted around a peripheral edge of the coupling portion and includes second and third through-holes respectively located corresponding to the driving section of the ratchet wheel and the switch of the direction changing unit.
Clench wrench
A clench wrench has a structure including a handle and an engaging head. The engaging head defines an engaging space. A clenching device is mounted on the engaging head. The clenching device includes a resilient clenching member fixed to the engaging head and having a free end. The clenching member has a clenching portion at the free end. The free end of the clenching member is bendable to selectively clench an object. A block is disposed on the engaging head and abuts against the clenching member and counteracts a force that causes the clenching portion to move from the first position to the second position.
Control device and work management system using same
A control device is provided with a communication unit and a processing unit. The communication unit makes communication with a tool that is used for the work of fastening a fastener (for example, a screw) and with an image pickup unit for capturing an image of the work site where the work is being performed. The processing unit executes a determination process of determining whether or not the work is being performed normally on the basis of the fastening torque applied to the fastener by the tool and the image captured by the image pickup unit.
Ratchet and socket assembly
A ratcheting tool has a drive tang with a socket retaining detent and a linkage to engage the detent. A locking element is disposed movably between a first position wherein the locking element engages the linkage when a first actuator is in a first position so that the locking element blocks movement of the linkage so that the detent remains in a socket-retaining position and a second position in which the locking element disengages the linkage. A storage device for retaining sockets has a frame and one or more docks attached to the frame, each dock having a first retainer member, a second retainer member, and a third retainer member, at least one of which is selectively movable with respect to a socket receiving space so that a socket is removable from the socket receiving space.
Reversible ratcheting tool with dual pawls
A ratcheting tool includes a head and a handle, and a gear ring disposed in the head defining a first plurality of teeth defining a first arc having a first radius. A first pawl is disposed in the head and defines a front face, a rearward face, and a second plurality of teeth which defines a second arc having a second radius. A second pawl is disposed in the head and defines a front face, a rearward face, and a third plurality of teeth which defines a third arc having a third radius. When the first pawl and the second pawl are disposed with their rearward faces in vertical alignment and their longitudinal center axes are disposed in a common plane, the second arc of the first pawl is offset from the third arc of the second pawl in a direction parallel to the longitudinal center axes.
Quick detachable wrench structure
A quick detachable wrench structure comprises: a wrench head portion, which has a hollow operation accommodation room and a top end portion disposed at an upper portion thereof; and a pressing member, which has a top pressing portion and a bottom plug portion, the bottom plug portion is embedded in the operation accommodation room, the top pressing portion is disposed at an upper portion of the top end portion, a bottom edge of the bottom plug portion is against to a bottom end of the top end portion in order to avoid the bottom plug portion taking off from the operation accommodation room.
RATCHET WRENCH WITH PLANET GEAR UNIT
A ratchet wrench includes a center gear connected to the top of the ratchet wheel and a disk is mounted to the center gear. Three planet gears is connected to the disk and engaged with the center gear. A rotary member is rotatably mounted to the disk and has inner teeth engaged with the planet gears. Two pawls are respectively engaged with the disk and the ratchet wheel. A shank extends through the rotary member, the disk, the center gear and is connected to the ratchet wheel. When rotating the rotary member, the planet gears rotate the center at high speed, and the center gear rotates the ratchet wheel to quickly rotate the object to be tightened or loosened.
Box end ratchet wrench with reduced ratcheting arc
A reduced arc box end ratchet wrench or ratchet drive wrench utilizes a multiple pawl ratchet assembly comprised of a body having an insert cavity to enclose critical components of an insert that is secured within the ratchet assembly. The insert is set into the wrench body and includes a plurality of pivoting pawls. Each pawl comprises a lever arm with ratchet engaging teeth. The pawl arms are positioned relative to the ratchet wheel to create “pawl swing arcs” and “reduced ratcheting arcs” to alternately or successively engage a portion of the teeth of a ratchet wheel at all times. This configuration allows smaller degrees between ratchet teeth and a smaller wrench rotation that is otherwise required to apply torque.
Ratchet wrench
A ratchet wrench is provided, including a main body, a lever member, a ratchet head, a switch assembly and a cover assembly. The cover assembly includes a lid member and a positioning member. The positioning member is embedded within a grooved portion of the main body so that the lid member is positioned to the main body. A surface of the lid member is flush with a surface of the main body.
Snap Ring Manipulation Tool
A snap ring manipulation tool for installation and removal of snap rings includes a frame that comprises a pair of members. The members are opposing, such that a first end of one member opposes a second end of the other. Each of a pair of first holes is positioned through a respective member proximate to the first end. Each of a pair of rods is fixedly coupled to a respective member proximate to the second end. The rod is slidably positionable through an opposing first hole. A biaser is operationally coupled to each member. Each of a pair of first tips is coupled to and extends from a first side of the frame. The frame positions the first tips for insertion into the complementary orifices of the snap ring. The biaser is positioned to diverge and converge the members to respectively widen and narrow the snap ring.
