A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.

A ratcheting tool may include a motor coupled to an output drive mechanism by a clutch assembly. A torque selector may be rotatably coupled to a housing of the tool, to provide for selection of a maximum output torque. The clutch assembly may selectively disengage the motor and the output drive mechanism, or slip, in response to detection of an output torque level, or resistance torque, that is greater than or equal to the selected maximum output torque level.

A device for clamping an object with adjusting plier mechanism is disclosed. In particular, a device is provided with a top jaw having a bottom handle, a slot, and a series of ridges located around the slot and top handle with a distal end. A pawl pivot, which includes an engagement element, is provided for extending through the bottom jaw and into a slot of the top jaw. The bottom jaw can include a slot for receiving at least part of the top jaw and bottom handle. The top jaw can include a slot for receiving at least part of the pawl pivot. The top jaw and bottom jaw pivot about a first axis of the coupling element, and the engagement element is moveable along a different axis from a first position to a second position.

A clamp includes a bar having top and bottom surfaces, a fixed jaw fixed to the bar, and a movable assembly movable along the bar. The movable assembly includes a movable jaw, an actuator that incrementally moves the movable assembly to apply a clamp force to a clamp load, a release lever to disengage the movable assembly to release a clamp force and permit free sliding of the movable assembly along the bar. The movable assembly may support a bearing surface formed of a low-friction material, positioned to prevent the movable assembly from binding to the bar when a clamp load is released. The release lever may be movable between a position engaging the bar, a position where the release lever disengages the bar, and another position engaging the bar, the third position being opposite the first position with the second position therebetween.

The invention is directed toward a tool assembly for optionally operating a tool body independently or in combination with a storage holder for polygonal shaped tools, such as a L shaped hex key. The tool assembly includes a tool main body that can act as a tool itself. The tool main body may comprise a housing, an adjustable securing mechanism, and a control member. The adjustable securing mechanism is mounted in the tool main body housing and is operatively connected with the control member. The adjusting mechanism is configured to accept and secure a tool of different sizes and shapes. The control member is rotatable to bias the adjustable securing mechanism to rotate around an axial direction in the housing so that the adjustable securing mechanism is moved in a manner to either secure a tool or release a tool.

A hand tool having an elongated handle, an elastically flexible drive gear, a plurality of roller members, and a cage member. The elongated handle has an interior annular wall that defines a cavity that supports the drive gear rotatably for movement between a radially compressed position and a radially decompressed position. The drive gear includes an inner periphery configured to engage a fastener, and an outer periphery containing circumferentially spaced pockets to receive a corresponding roller member. The cage member is supported in the cavity to support the drive gear in a manner that facilitates movement of the roller members to cause movement of the drive gear to the radially compressed position to apply a torquing force on the fastener in response to selective rotation of the handle in a first direction. The hand tool may thus be operated as a normal gear ratchet wrench under traditional load conditions.

A hand tool has an elongated handle, and includes an elastically flexible drive gear along with a plurality of roller members, all supported in a cage member at one end of the handle. In response to selective rotation of the handle, the roller members operate to radially compress the drive gear about a fastener when the handle is rotated in a direction that imparts a torquing force to the fastener. The hand tool provides a haptic and audible ratchet feedback when the handle is rotated in a direction opposite the first direction to untorque the fastener.

A striking hand tool includes a grip component where an external surface has a front arc half and a rear arc half, wherein an area of the grip is smaller in a first cross sectional plane further from a head of the tool than a second plane closer to the head portion. A ρ value of the front arc half in the first cross sectional plane is less than approximately 0.45. A measurement from a first axis to a frontmost point in the first cross sectional plane is between 17.5 mm and 19 mm. A ρ value of the front arc half in the second cross sectional plane is less than approximately 0.5. A measurement from the first axis to a frontmost point in the second cross sectional plane is between 18.5 mm and 20 mm. Methods of manufacturing and striking hand tools having desirous durometer measurements are also disclosed.
