An electric rapid ratchet wrench includes a driving device mounted in a body to which a power device is mounted. A transmission device is mounted between the driving device and the power device and is rotatably mounted to the body. The transmission device transmits a torque from the power device to drive the driving device. A clutch device is mounted between the driving device and the power device. The clutch device includes a driven member and a driver member movable in a radial direction perpendicular to a rotating axis to disengageably engage with the driven member. When a large resistance larger than the torque of the power device is encountered at a position while the driving device is driving a fastener, the driver member repeatedly engages with and disengages from the driven member. The body is manually rotatable to forcibly drive the fastener through the position via the driving device.

A ratchet tool includes a first rotating assembly including a seat, a first pawl, and a second pawl. The seat defines a first recess and a second recess. The first pawl is pivotally engaged in the first recess and the second pawl is pivotally engaged in the second recess respectively. The first pawl has a first protrusion and the second pawl has a second protrusion respectively. Further, a second rotating assembly including a ratchet wheel. The ratchet wheel includes the seat inserted therein. Further, a direction control assembly includes a shifter and a pushing member. The shifter is rotatable with respect to the seat between a first position in which the pushing member urges the first protrusion, a second position in which the pushing member urges the first and the second protrusions, and a third position in which the pushing member urges the second protrusion.

A ratchet wrench comprises a handle defining a cavity including a plurality of teeth on an inner periphery thereof, a wheel, a biasing spring ring, and at least one tooth pawl mounted in recesses formed on the outer periphery of the wheel. The wheel is rotatably mounted inside the cavity and the pawls are biased by the spring ring to engage the plurality of teeth on the inner periphery of the cavity when rotated in a first direction, and to slide over the teeth when rotated in a direction opposite the first direction.

The multi-function tool described herein includes a case, a drive ratchet installed in the case, a threading die held within the case, a file attached to the case such that a working surface of the file is exposed, a wrench tool removably secured to the case by a wrench retaining feature formed in the case, socket tools removably secured to the case by socket retaining features formed in the case, and a bar extension tool removably secured to the case by a bar extension retaining feature formed in the case. The ratchet has a fitting exposed at the top of the case, and a toggle switch exposed at the bottom of the case. The bar extension tool is compatible with the socket tools, the fitting of the ratchet is compatible with the socket tools, and the fitting of the ratchet is compatible with the bar extension tool.

A ratchet wrench capable of rotating quickly and driving rotation includes a handle, a rotary head, a positioning mechanism, and a sleeve. The handle includes an arm and a bar body. The bar body includes an accommodating slot; the arm includes a through hole. The rotary head is connected to the arm and includes recess portions. The positioning mechanism includes a positioning element, a resilient body, and a block element. The resilient body receives the positioning element and is received in the through hole, the positioning element is correspondingly disposed in any of the recess portions, and the block element is connected to the positioning element. The sleeve receives the bar body and operably drives the block element to slide in the accommodating slot, so that the positioning element is positioned and selectively engaged with any recess portion.

A mechanism that is non-engaging in the forward direction and prevents direction change, comprising a dual ratchet sleeve (1). The dual ratchet sleeve is provided in the axial direction a one-way forward ratchet ring gear and a one-way reverse ratchet ring gear; a pawl base (2), the pawl base being provided with a first pawl (21) and a second pawl (22) capable of moving in a direction perpendicular to the axis of the dual ratchet sleeve; an eccentric drive mechanism (3) for driving the first and second pawl to act, the axis of the eccentric wheel axle (32) of the eccentric drive mechanism being perpendicular to the axis of the dual ratchet sleeve; a tool handle (4) for driving the pawl base to rotate, the tool handle being connected to and fixed on the eccentric wheel (31) or the eccentric wheel axle (32) of the eccentric drive mechanism so as to enable the linkage of the tool handle and the eccentric wheel. The mechanism that is non-engaging in the forward direction and prevents direction change meets the working requirements under multiple states and directly enables torque transmission and state change by means of the handle.

A powered ratcheting wrench includes a main housing defining a grip portion, a motor having a motor drive shaft, a drive assembly coupled to the motor drive shaft and driven by the motor, and an output assembly coupled to the drive assembly. The output assembly includes an output member that receives torque from the drive assembly, causing the output member to rotate about an axis. The powered ratcheting wrench further includes a head housing coupled to the main housing and supporting at least a portion of the drive assembly. The head housing is composed of an aluminum alloy resulting in a center of gravity for the power tool to be proximate the grip portion.

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.

An example hand wrench is provided. The hand wrench may include a handle (15) having a handle opening (12), and an orbital member (24) received within the handle opening. The orbital member may be configured to move orbitally about a point axis. The hand ratchet wrench may further include a driver affixed to the orbital member. The driver may be configured to receive a socket that interfaces with a fastener to turn the fastener.

A ratchet wrench having multiple driving modes with torque sensing function includes an annular head, a driving unit, a control unit, a rotary member, a forcing unit and at least one torque sensor. The annular head receives the driving unit therein and a shaft extends from the annular head. The driving unit has a first toothed ring engaged with a first pawl, and a second pawl engaged with inner teeth of the annular head. The rotary member is rotatably inserted in the shaft, and has two ends to the driving unit and the forcing unit respectively. The forcing unit includes a tubular handle and a display unit. The torque sensor is mounted on the shaft. The shaft inserts into an axial chamber of the handle. The torque sensor is positioned between the axial chamber and the shaft. When the shaft is bended by the handle to produce a deformation. The torque sensor senses the deformation of the shaft to generate a torque sensing signal, so that the display unit converts the torque sensing signal to a torque value and displays the torque value.
