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.

A reversible ratchet tool includes a cage-type reversing mechanism including a cage member for shifting rollers from their first positions to their second positions. The structure and configuration of the cage member is improved with resilient members for preventing the rollers being stuck unintentionally when the rollers are positioned either in the corresponding first positions or the corresponding second positions, while being capable of maintaining and restricting the rollers upright in place when the rollers are shifted from the corresponding first positions to the corresponding second positions.

Disclosed is a high-loading ratchet tool, which has a main body, a braking structure and a working part, wherein the main body forms a first receiving groove, a second receiving groove and a third receiving groove, and the second receiving groove and the third receiving groove are mainly composed of two circular surfaces, and the braking structure is disposed on the main body. The braking structure has a ratchet, and the two ends of the ratchet respectively form a first shaft segment and a second shaft segment. The first shaft segment is disposed in the second receiving groove, and the second shaft segment is disposed in the third receiving groove. According to this, the relative force of the first shaft segment and the second shaft segment and the main body is dispersed, and enhancing the working part restrictions on external torsion.

A fire hydrant tool for opening a fire hydrant in a controlled manner includes a cordless tool that has an output shaft and a trigger. A socket is attachable to the output shaft of the cordless tool and the socket has dimensions matching a top nut of a fire hydrant thereby facilitating the cordless tool to open the fire hydrant. A rod is attachable to the handle of the cordless tool thereby facilitating the rod to be gripped for manipulating the cordless tool. A ratchet driver is attached to the rod and the socket is attachable to the ratchet driver when the cordless tool has insufficient torque to loosen the top nut. A prying tool is coupled to the rod and the prying tool has a claw element and a hook element to grip an object for prying the object.

A fastener driving device including an elongate shaft extending between the driving head and the handle is provided that has a torque limiting mechanism disposed partially within the handle and extending through the elongate shaft into engagement with the driving head. The torque limiting mechanism enables the driving head to drive the fastener into the substrate without exerting more than a predetermined maximum torque on the fastener, thereby avoiding damage from being done to the fastener and/or the substrate. A ratcheting mechanism is disposed within a torque gear of the torque limiting mechanism to provide a ratcheting function to the tool with a small profile for the tool.

A driving tool is provided, including a grip body, a main body, a driving assembly, a press handle, a driven member and a toothed bar. The main body is rotatably disposed on the grip body. The driving assembly is arranged on the main body. The press handle is disposed on the grip body to drive the driven assembly. The driven assembly is disposed on the main body. The toothed bar is connected to the driven assembly and the driving assembly.

An electric ratchet wrench as one example of the ratchet wrench includes an electric motor, a holder that rotatably holds a socket via a one-way clutch mechanism, and a spindle configured to convert a driving force from the motor into a reciprocating rotation motion of the holder. A space is provided between the socket and the holder. The space includes large interval portions and small interval portions. The small interval portions are adjacent to the large interval portions in a rotation direction (lock direction) of the socket and have distances smaller than distances of the large interval portions. Additionally, the one-way clutch mechanism includes columnar locking pins disposed between the spaces and have a diameter with a size equal to or less than the distances of the large interval portions and exceeding the distances of the small interval portions.

A high strength wrench includes a head portion, a shaft and a handle. A length of the shaft is multiple times of a length of the handle. At least one slot extends along a longitudinal direction of the shaft and is formed at a circumferential surface of the shaft. A cross section shape of the shaft has a structural profile of an outer side with a relatively greater thickness and an inner portion of a relatively smaller thickness. Accordingly, the shaft has a greater structural strength to allow the wrench to bear operations of high torque.

A reversible ratchet tool includes a cage-type reversing mechanism including a cage member for shifting rollers from their first positions to their second positions. The structure and configuration of the cage member is improved with resilient members for preventing the rollers being stuck unintentionally when the rollers are positioned either in the corresponding first positions or the corresponding second positions, while being capable of maintaining and restricting the rollers upright in place when the rollers are shifted from the corresponding first positions to the corresponding second positions.

The invention relates to a roller wrench comprising: a body with a circular chamber; a driving member being a regular polygonal component capable of rotating in the chamber; and a plurality of rollers installed in the chamber, Each of the rollers is located between a side of the driving member and a peripheral wall of the chamber; one end of each of the rollers is pivotally connected to an end surface of a reversing knob, so that the reversing knob drives the rollers to displace simultaneously. Thereby, the components of the roller wrench can be effectively latched with one another, and a torque value of the roller wrench will not be reduced.
