摘要： A toggler structure for a ratchet wrench includes an elongated toggler arranged between a locking member and a direction switch member of the ratchet wrench. The rear side of the toggler includes at least two connecting portions. At least two elastic elements are arranged between the connecting portions of the direction switch member and the toggler in order to provide an elastic force to push the toggler to abut against the locking member. The elongated toggler can be applied to a ratchet structure of a greater thickness in order to increase the structural strength and operational torque of the ratchet wrench. Furthermore, the elastic elements can provide a uniform elastic force in the length direction of the toggler, thereby allowing the locking member to engage with the ratchet structure properly.

摘要： A tool with a handle indexably retained to a pin. The pin is coupled to a head of the tool. The pin allows an angle between the head and the handle to be adjusted, thereby allowing the tool to be used in hard to reach places. The pin is coupled to the head to limit axial movement without the need of a threaded fastener. The reduction of axial movement allows for smooth, consistent operation of the tool.

摘要： A driving tool includes a housing, a follower assembly at an end of the housing, a driving assembly at another end of the housing, and a pressing handle. The driving assembly includes a first driving member, a second driving member, and a one-way rotation structure between the first driving member and the second driving member.
The pressing handle is engaged with the first driving member to drive it to rotate. The first driving member drives the second driving member to rotate toward a specific direction via the one-way rotation structure. Thereby, the follower assembly is driven to rotate toward a specific direction.

摘要： A power ratchet tool capable of accessing narrow and elongated spaces includes a handle, a head, and a mounting cover. The handle has a transmission device having an idler and an eccentric spindle. The idler has a toothed portion. The eccentric spindle has a gear portion and an abutting portion. The gear portion engages with the toothed portion. The head is mounted to the handle and has a length being between 3 inches and 28 inches, an extended housing and a bushing. The extended housing is mounted to the handle and has a receiving groove. The receiving groove is recessed in the extended housing. The bushing is received in the receiving groove. The handle and the head are mounted together by the mounting cover. The abutting portion of the eccentric spindle abuts against the bushing, such that the bushing sleeves the eccentric spindle.

摘要： A shifting device includes a sleeve module and a shifting member movably disposed in the sleeve module. The sleeve module has a through hole. The through hole is divided into a first hole region, a buffering region, and a second hole region. The shifting member includes a third operating section and a fourth operating section. The shifting member is movable between a first position and a second position. The fourth operating section of the shifting member is situated in the buffering region when the shifting member assumes the first position, and the second hole region and the third working hole are adapted to turn a fastening member. The third operating section of the shifting member is situated in the buffering region when the shifting member assumes the second position, and the first hole region and the fourth working hole are adapted to turn the fastening member.

摘要： The present invention provides a pipe union that uses mechanical advantage from leverage between a locknut with circumferential torque openings coupled to a tubular first portion and a torque ring with torque slots coupled to a tubular second portion to tighten the union. The tightening can occur without the need of a hammer impact on lugs. Initial tightening can at least partially align longitudinally the radial holes with the radial slots. Final tightening can occur by rotating the torque openings relative to the torque slots using mechanical advantage. Optionally, the pipe union can provide for a ratcheting mechanism to turn the locknut on the tubular first portion to engage the tubular second portion and exert a preliminary torque on the union. The pipe union design also provides a self-energizing elastomeric seal or metal seal. Angles on load shoulders can assist in creating preloads on the union to seal the components.

摘要： A hand tool for fastening a fastener, such as a screw. The hand tool comprises a handle and a rotatable fastening head connected to a first end of the handle, and engaged with a manually driven actuator. The hand tool further comprises a fixed fastening head connected to a second end of the handle, which is configured to apply a configurable fastening torque to the fastener The fixed fastening head is selectively pivotable with respect to the handle about an axis parallel to the center axis of the fixed fastening head.

摘要： A screwdriver having a changeable direction freewheel lock, having a drive output member that is mounted so as to be rotatable about an axis in a bearing eye of a drive input member and has a circumferential toothing and a drive-output profile portion, and locking members that are inserted in a pocket of the drive input member and each have a locking toothing for engaging with the circumferential toothing in a manner preventing rotation. What is essential is that the locking members are two bodies that are movable relative to one another, can be displaced in an articulated manner with respect to one another and each have a switching extension which project into the same switching recess of a switching member.

摘要： A method for operating a ratchet wrench having a tangential belt drive mechanism and a ratchet gear therein, including the steps of momentary pulling on the driven end of the belt for rotating the ratchet gear during a forward cycle; continually applying a first resilient tension force on the return end of the belt; continually applying a resilient compression force on the driven end of the belt of a same magnitude as the first resilient tension force toward the return end of the belt, and relaxing the step of pulling and allowing the belt to return to an initial position of the belt before the step of pulling. In another aspect of the present invention, there is provided a tangential drive mechanism comprising a first and second springs, one on each side of the ratchet gear and each acting on the belt toward a return end of the belt.

摘要： A ratchet wrench comprising a ratchet head with a cylindrical bore having a central axis; a handle; a drive member (26) with a rotation axis (W-W) retained within the cylindrical bore for rotation about the central axis; and a toothed ratchet pawl (42); a cylindrical array of straight ratchet teeth arranged about one of the cylindrical bore or the drive member; and a pawl recess (36) arranged to support the pawl. The pawl may mesh with the ratchet teeth for transmission of rotation of the handle in a first direction to the drive member about the rotation axis or disengage from the ratchet teeth to decouple rotation of the handle in a second direction from the drive member. Support (37a, 37b, 46, 48, 50) for the pawl in the recess is shaped to accommodate divergence between the central axis and the rotation axis.
