The present invention provides a connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) to connect a first tool (80, 90) to a second tool (90,80), the connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) comprising at least one shell member 30 which clamps a first end to said first tool (80, 90) and a second end of said at least one shell member 30 to engage with said second tool (90,80), whereby relative rotation between said first tool and second tool is prevented, and axial separation of said first tool (80, 90) and second tool (90,80) is prevented or is assisted in being prevented. This results in a safer combination of the first tool (80, 90) and second tool (90,80), and allows for a one handed operation of the combination.

A portable power tool including, within a housing: an electric motor having a drive shaft, an epicyclic reduction gear having planetary gears meshing with a central gear of the drive shaft of the electric motor, the reduction gear being provided with an output shaft that is rigidly connected to a ball screw of a ball screw/nut mechanism and is coaxial to the ball screw, and a support bearing connecting the output shaft to the housing. The tool includes at least one stabilization bearing axially offset relative to the support bearing. The stabilization bearing connects the output shaft of the epicyclic reduction gear to the housing by at least one intermediate part selected from: the drive shaft of the electric motor, planet-carrier axles of the epicyclic reduction gear, and epicyclic reduction gears of the epicyclic reduction gear. The structure is of use in shears, in particular sheet metal shears.

The subject matter relates to a drywall bead press that is able to cut drywall at various angles. The anvil anchors the device to the dry wall, allowing the handle to be rotated to the desired angle. Once the desired angle has been chosen, the upper handle mechanically forces the blade into the drywall.

A power tool includes a housing having a first portion defining a forward end of the housing, a second portion defining a rearward end of the housing, an upper surface extending rearwardly from the forward end, and a lower surface extending forwardly from the rearward end. The power tool also includes a motor positioned within the housing, a drive mechanism coupled to the motor and positioned within the housing, an output element coupled to the drive mechanism at the forward end of the housing, a battery pack supported at the rearward end of the housing and electrically coupled to the motor, and an actuator operable to selectively power the motor to drive the drive mechanism and the output element. The actuator is supported by the housing forward of and above the battery pack.

A power tool accessory (e.g., a shear accessory) includes an accessory housing, an input shaft, a working tool, and a brace. The input shaft is driven by a power tool and drives the working tool. The brace rigidly connects the accessory housing to a power tool housing. The brace includes a collar coupled to the accessory housing, a clamp assembly that may be rigidly connected to the power tool housing, and an arm assembly connecting the collar to the clamp assembly. The collar allows selective rotation of the accessory housing relative to the collar while the brace rigidly couples the accessory housing to the power tool housing. The arm assembly may have a single arm. The clamp assembly may be coupled to a base of a handle of the power tool with arm assembly at an angle to a working axis of the power tool.

A cutting device for an oscillating multifunction machine tool includes at least one shearing unit with at least one base body, a cutting edge and a backing edge. The cutting edge and the backing edge bound a cutting opening for inserting a workpiece. The cutting device further includes a tool interface for attaching the shearing unit to a tool holder of the multifunction machine tool. The cutting edge and the backing edge are disposed rigidly relative to one another and an angular bisector of a cutting opening angle of the cutting opening is disposed in a plane perpendicular to an oscillation axis of the tool interface, at an angle between 70 and 110 to a radial axis of the tool interface, which is perpendicular to the oscillation axis and passes through an intersection point of the cutting edge and the backing edge.

A 360 rotatable drill shear attachment has a housing with forward extending shear blades and a rearward extending drive bit connectable to a chuck of a portable hand drill. A cowling is fixed to a mounting flange and rearward of the shear housing protectively covering the drive bit and drill chuck. A circular clamp is rotatable and securable to the mounting flange. Left and right rails slide-ably adjust lengthwise and pivotally extend from the clamp along the left and right sides of the drill body to a point beyond the rear of the drill body to a drill rear end. A connector adjustably is fastened to the rear ends of the rails to adjustably draw the ends together for securing the shear attachment to the drill body. The clamp may be loosened to rotate the mounting flange of shear attachment, and shear blades, within the clamp for shear blade orientation anywhere along a 360 axial arc. After which, the clamp is tightened for safe, one-handed operation of the drill with the shear attachment and shear blades oriented in the desired direction.

A scissors attachment can also be attached to the reciprocating tool for cutting one or more sheets of material. The scissors attachment includes an extension bar and first and second blades pivotally attached. A tool chuck coupling connects one of the blades to the reciprocating tool chuck of the reciprocating tool. A bar slot can be integrally defined on the tool or defined on the neck mount assembly for receiving and securing in place the extension bar. A method of stabilizing a cutting instrument is also provided. Additionally, a method of cutting material is provided.

The present invention provides a connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) to connect a first tool (80, 90) to a second tool (90,80), the connection device or tool (10, 110, 210, 310, 410, 510, 610, 1110, 2110, 3110, 4110) comprising at least one shell member 30 which clamps a first end to said first tool (80, 90) and a second end of said at least one shell member 30 to engage with said second tool (90,80), whereby relative rotation between said first tool and second tool is prevented, and axial separation of said first tool (80, 90) and second tool (90,80) is prevented or is assisted in being prevented. This results in a safer combination of said first tool (80, 90) and second tool (90,80), and allows for a one handed operation of the combination.

A power tool is disclosed and includes a housing and a motor disposed within the housing. The power tool further includes a first blade and a second blade movable relative to the first blade by the motor. During operation, a cutting stroke length of the first blade relative to the second blade is selectively adjustable based on a direction of rotation of the motor.
