A method for manufacturing an operation rod of a wrench assembly for disassembling a fan clutch, including following steps of: preparing a rod material; fixing the rod material on a forging mold; carrying out a forging process to produce a semi-finished head; carrying out a cutout process, cutting the remainder structure out of the semi-finished head; obtaining a finished product of a head portion, the head portion including two wing plates and a shaft which are integrally formed.

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.

A flexible head joint for a tool, such as a motorized ratcheting-type tool. The flexible joint also allows an output mechanism of the tool, such as a ratchet head, to be disposed at an angle with respect to a housing to the tool, which houses a motor. For example, the first shaft is pivotably coupled to a first connector, which may have a tongue shaped portion. The second shaft is pivotably coupled to a second connector, which may have a slotted portion adapted to receive the tongue portion. This provides two pivot points that have parallel axes.

Disclosed is a torque-adjustable wrench for a narrow space. The present disclosure relates to the technical field of assembly tools. The wrench comprises an elongated upper cover plate and an elongated lower cover plate, the space between the upper cover plate and the lower cover plate forms a mounting space, one end of the mounting space is provided with a screw pre-tightening mechanism, and the other end of the mounting space is provided with an adjustable screw locking mechanism. During use of the wrench, first, the screw pre-tightening mechanism is used to pre-tighten a screw to be assembled, and then the adjustable screw locking mechanism is used to perform locking operation on the pre-tightened screw. By means of the wrench, the mounting and dismounting of a screw in a narrow space can be conveniently achieved.

The pivoting and extending interchangeable hand tool device disclosed herein may comprise a tool head and a torque arm that pivot relative to one another, a secondary torque arm for extending length and increasing appliable torque, and a “T”-handle for additional support. The pivoting and extending interchangeable hand tool device may further comprise a plurality of tool heads that may be interchanged within the secondary torque arm, and may be provided commercially in a multiple-tool set. The device is designed to overcome the shortcomings in the prior art, which specifically include the ability to work in tight spaces while reducing the loss of torque when pivoting a torque arm, the loss of strength inherent in an extendable torque arm, and the bulkiness of a “T”-handle.

A fixed-angle ratchet adapter that uses gears to change the rotation angle for a ratchet or impact driver. One variation is meant to be used at right angles and another variation is meant to be used at 45 degree angles with either used on its own with a ratchet or impact driver or used in concert with various universal joints currently on the market to improve functionality.

A tool (1) for actuating an adjustment element (2) of a sanitary faucet (3), comprising at least: a shaft (4) having a longitudinal axis (5); and a drive geometry (6), which is disposed on the shaft (4) and can be connected to the adjustment element (2) for transmitting a torque, wherein the drive geometry (6) can be elastically deformed such that the drive geometry (6) at least partially disengages from the adjustment element (2) when a predetermined torque is reached;

a kit (15) comprising a sanitary faucet (3) and the tool (1); and

the use of the tool (1) for actuating an adjustment element (2) of a sanitary faucet (3).

A light bulb changer including an elongated pole having a first configured to be rotated about a longitudinal axis thereof, a support structure engaged with the elongated pole near a second end of the elongated pole, and a bulb holder extending from a second end of the support structure. A pair of cog belt pullies and a belt positioned therebetween transfer the rotation of the elongated pole about tis longitudinal axis to rotation of the bulb holder about a central axis thereof that is spaced apart from the longitudinal axis of the elongate pole. The bulb changer enabling removal and replacement of light bulbs of overhead light fixtures with a user safely positioned on a floor under the light fixture with a clear line of sight of the bulb and without the need for ladders or other elevations.

The present invention relates to an ergonomic plier tool. More specifically, the invention relates to a piston actuated ergonomic plier tool having a 360-degree rotative and exchangeable head. The tool includes a body, lever, head cylinder, piston and jaw assembly. The disclosed tool allows an operator to work in tight spaces with her hand in one plane, while cutting/manipulating an object in an infinite number of planes different from that of her hand.
