A power tool comprises a housing, a motor assembly and an impact assembly configured to be driven by the motor assembly. The impact assembly comprises a hammer defining a hammer chamber therein and an anvil at least partially disposed in the hammer chamber and configured to rotationally drive an output shaft. The anvil comprises a body portion, an anvil chamber defined therein, and a reciprocating member configured to selectively move radially outwardly relative to the body portion to be selectively impacted by an impact member of the hammer so that the hammer selectively imparts rotational movement to the anvil. The anvil includes an active valve configured to control discharge of fluid from an anvil chamber to the hammer chamber. The active value variably opens based on variance of one or more physical characteristics of the fluid (e.g., at least one of volume, temperature, pressure, or viscosity of the fluid).

Impact driver

A power tool including a housing and a motor housed in the housing. There is a spring engine housed in the housing and a driver blade driven by the spring engine. Additionally, the power tool holds a pipe clamp configured to be driven into a workpiece by the driver blade.

Pipe clamp, pipe clamp driver and anti-backdrive mechanism

A fastening tool for driving a fastener into a workpiece is described herein. The fastening tool includes a contact trip, a magnet, and a magnetometer. The contact trip is disposed at a first end of the fastening tool and is configured to move toward a second end of the fastening tool opposite of the first end when the contact trip engages the workpiece. The magnet is configured to generate a magnetic field. The magnet is coupled to the contact trip such that movement of the contact trip causes the magnet to move. The magnetometer is configured to detect a change in the magnetic field generated by the magnet when the magnet moves relative to the magnetometer and, based on the detected change in the magnetic field, to generate a signal indicating when the contact trip engages the workpiece.

A barbed staple for installing fencing wire onto a fence post. The staple has a crown section and a leg section. The crown section has an arcuate crown portion and a radiused portion, and the leg section has a pair of leg portions that extend in parallel from the radiused portion of the crown section. At least one barb protrudes from each of the leg portions, the barb having projecting points. The distance between the distal edge of the projecting points defines an outer leg width. The crown portion of the crown section has a greater width than the pair of leg portions in parallel. The outer crown width is greater than the outer leg width.

Fencing staple

A stapling tool assembly may include a nosepiece assembly with a driver channel through which a staple is driven into a workpiece. The stapling tool assembly may also include a wire alignment contact trip with a contact foot. The contact foot may include a peripheral guide wall that defines a workpiece contact edge. The workpiece contact edge may include at least one wire alignment recess and at least one opposing wire alignment recess in the workpiece contact edge. The at least one wire alignment recess and the at least one opposing wire alignment recess can cooperate to define a first and a second wire positioning path to align the wire in two different orientations relative to the drive channel. The at least one wire alignment recess can have a first overall length that is different than a second overall length of the at least one opposing wire alignment recess.

Stapling tool assembly including a wire alignment contact trip

An electric fastener driving tool assembly can include a driver designed to drive a fastener into a workpiece. The driver can reciprocate along an axial driver path between an extended position and a home position. A home position sensor can be located laterally adjacent the axial driver path. The home position sensor can be located to sense the presence of the driver in the home position when a lateral distance between the driver and the sensor changes.
