摘要： The present invention provides a ratchet wrench attachment for a drill. The device includes an elongated body including a ratchet head disposed on one end therof, wherein the ratchet head is removably securable thereto. The ratchet head includes an interior gear, which is affixed to a tube having a central aperture. A removable drive shaft-secured to the central aperture, and thus connected to the gear—-extends outward from the first end of the elongated body. The drive shaft extends through the elongated body beyond a periphery the opposite end of the elongated body. In one embodiment, the drive shaft comprises a hexagonal cross-section, whereby the drive shaft may be secured within the chuck of a power drill. The power drill causes the drive shaft to rotate, which, in turn, causes the ratchet head to rotate in a desired direction. The device can be used with any ordinary power drill.

摘要： A hand tool including a control element for receiving one or more finger digits of a user. The control element is positioned on the body component and may be in the form of an aperture defined by a perimeter surface. A user places one or more fingers within the control element and applies pressure to rotate the body component.

摘要： One or more techniques and/or systems are disclosed for a tool driver device that can apply counter-torque to the device while applying torque to a target component that is engaging a target base. The example device can be operated by one hand to actuate a power input component that provides the desired torque, while providing counter-torque to offset rotation of the device. A selectably engaged counter-torque component is selected to complement the target base, to operably hold it in place during use. A power input provides power to apply rotational force to drive a selectably coupled tool, which has been selected to complement the target component engaged with a target base. The counter-torque component is operably engaged with the base, which applies counter-torque to the torque provided by the target component.

摘要： A ratchet tool comprises a base, a ratchet body, a switching member and a pawl member. The base has a rail and is movable with linear motion along the rail between a first position and a second position, the ratchet body has plural teeth, and the pawl member is engaged with the switching member and comprises plural ratchet teeth, a first abutting portion and a second abutting portion. When the switching member is movable to the first position, the pawl member is pivotally rotated to a third position to make the ratchet teeth mesh with the teeth and the first abutting portion abut against the base, therefore the ratchet body enables to rotate along a first rotation direction. When the switching member is movable to the second position, the pawl member is pivotally rotated to a fourth position to make the ratchet teeth mesh with the teeth and the second abutting portion abut against the base, therefore the ratchet body enables to rotate along a second rotation direction.

摘要： 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.

摘要： A retaining structure for a drive gear of a ratchet wrench. The drive gear has a partial internal bore that receives a gear retainer that is coupled to the tool housing via screws. The gear retainer can further be rotatably coupled to the drive gear to retain the drive gear within the head of the tool without requiring a cover plate. By potentially avoiding the cover plate, the ratchet wrench head can be thinner compared to conventional ratchet wrenches and the ratchet wrench seal can be improved.

摘要： A ratchet wrench has a head. The head is recessed with a driving chamber. A ratchet wheel is disposed in the driving chamber. The driving chamber is covered with a cover plate. The head further has a first shaft hole. The cover plate has a second shaft hole. Two sides of the ratchet wheel are provided with a first shaft portion inserting through the first shaft hole and a second shaft portion inserting through the second shaft hole, respectively. A bearing ring is sleeved onto the second shaft portion. An outer periphery of the bearing ring abuts against an inner wall surface of the driving chamber for positioning and lubricating the ratchet wheel, so that the ratchet wheel can rotate smoothly.

摘要： A ratchet wrench includes a main body, a ratchet wheel, a pawl member, and a direction control unit. The main body is provided with a first receiving recess, a second receiving recess, a third receiving recess, a first abutting face, and a second abutting face. The pawl member is provided with an engaging portion, a cavity, two first abutting portions, and two corners. The direction control unit includes a rotation member, a push member, and an elastic member. The rotation member is provided with a cylindrical block, and two second abutting portions. The push member is provided with a push face and a receiving space. The push member is restricted by the first abutting face and restricts the rotation member such that the rotation member is mounted in and will not be detached from the third receiving recess.

摘要： A ratchet wrench with electric assistance includes a wrench body, a ratchet device, a pawl device, and a switch device. The switch device is configured for optionally gearing the pawl device with the ratchet device, so that the ratchet wrench is operated in a clockwise or counterclockwise direction. During the directional changing process, the switch device optionally engages the first gear and the second gear with the transmission gear of the power device, such that the power device transmits the power to the ratchet device for controlling the clockwise or counterclockwise rotation of the ratchet device, realizing the ratchet wrench with an electric assistance function.
