The invention provides a dual-purpose handle, comprising a body, wherein mounting holes are provided in the body and are used for connecting to functional members; the mounting holes are provided in the body in both an axial direction and a radial direction; axial and radial mounting holes provided in the body can enable the handle and the functional members to easily and quickly switch between two connection forms, i.e. straight and T-shaped; and torsional torques that are different in magnitude can be output by means of different connection manners under the action of the same operation force. Clamping devices fitted with the functional members are arranged in the mounting holes; and when the functional members are connected to the handle, the clamping devices can fix the functional members and prevent same from rotating in a cavity of the body of the handle. The axial and radial holes of the handle are configured to be through holes, so that the handle can be adapted to guide needles of different sizes passing through same and is suitable for minimally invasive surgery, thereby further expanding the range of use of the handle.

A hand tool is provided for removing a secondary liner from a tape carrier of a two-sided adhesive tape where the opposing primary side of the tape carrier is attached to a surface. The hand tool includes a handle. One end of the handle may include a handle fulcrum depending from the handle. A plurality of sharp points together define a mathematical line. The plurality of sharp points also define point axes which together define a mathematical plane. The mathematical line is coincident with the mathematical plane. The mathematical plane defines an acute angle with respect to the handle and to the handle fulcrum.

A tri-pad scrubbing device primarily used for cleaning vehicles where the scrubbing pads are powered by a single gear motor and each pad is capable of rotating and tilting to conform to the compound curves of a vehicle to allow the pads to maintain full contact with the surface being scrubbed. The tri-pad assembly is attached to the distal end of an adjustable length extension pole. A rechargeable battery power supply, which powers the gear motor, is removably mounted near the proximal end of the extension pole. The tri-pad assembly is attached to the distal end of the extension pole via a rotating and locking hinge mechanism. A push button switch is provided near the extension pole handle end.

A handheld measurement, search and safety device that includes a main frame having a handle, an extendable member that slides outwards from the main frame in measured increments, and an interchangeable support brace comprising either a buttstock or arm brace to allow responders to use the extendable member to survey hazardous materials at a distance, or a one-handed configuration used to survey hazard materials in confined areas. The handheld measurement, search and safety device includes a plurality of picatinny rails disposed on both the main frame and extendable member to removably mount a host of different field survey instruments and/or tactical accessories for detecting, locating, identifying, measuring, or sampling hazardous materials including radioactive materials or toxic chemicals.

A reconfigurable modular brush has a brush head including brush-head upper and lower surfaces extending longitudinally along a brush-head axis between brush-head first and second ends. Laterally opposed brush-head first and second sides extend between the brush-head upper and lower surfaces and longitudinally between the brush-head first and second ends. A bristle array is defined by a plurality of bristles protruding from the brush-head lower surface. A brush handle includes a grip portion and a brush-head mount, the brush handle having a lengthwise extent disposed generally along a handle axis between handle proximate and distal ends. The brush head and brush-head mount are cooperatively configured such that the handle can selectively capture and retain the brush head. Moreover, the longitudinal orientation in which the brush head is captured and retained by the brush handle is selectively reversible.

Rotatable handles and related methods are disclosed herein. In one form, the handle has a clip member that fits around a cylindrical object and a handle. The clip member includes a track that guides rotation of the handle about a longitudinal axis of the cylindrical object. The handle includes an actuator that operates a braking member which comprises a braking surface that is movable into and out of contact with the track. When the braking surface is out of contact the track, the handle is movable relative to the track when permitting the handle to rotate about a longitudinal axis of the cylindrical object. Rotating the handle about the longitudinal axis of the handle operates the actuator, causing the braking surface to move into and out of contact with the track. Various methods are also disclosed herein with respect to the rotatable handle.
