A mechanical device for grasping an object includes a receiver having a distal end shaft with an internal bore, the internal bore defining a recessed track. The recessed track defines a curvilinear path having two sets of resting peaks, each set of resting peaks being at a different height relative to a centerline of the curvilinear path. An actuator is slidably engaged with the receiver and includes a central shaft and an activator disposed at a distal end portion of the central shaft. A rotatable sleeve is disposed within the internal bore of the receiver and is coupled to the actuator. The rotatable sleeve has opposed protrusions, the opposed protrusions being disposed within the recessed track of the receiver. A pilot is secured to a distal end portion of the receiver and a grasping device is mounted to the pilot and coupled to the activator.

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.

A tool includes a grasping mechanism, an extendable pole operably connected to the grasping mechanism at a free end thereof, and a handle mechanism for manipulating the grasping mechanism. The handle mechanism is operably connected to the extendable pole.

A repositionable power wrench includes a housing, a motor arranged inside the housing, and an output shaft, which is rotationally connected to the motor and telescopically arranged with respect to the housing to allow axial movement of the output shaft with respect to the housing between a fully extended position (E.sub.max) and a fully compressed position, with a resilient member being arranged to urge the output shaft towards the fully extended position (E.sub.max). The power wrench also includes or is connectable to a positioning system arranged to monitor a position of the power wrench. The output shaft includes an output end arranged to interact with a fastener. A sensor is arranged to monitor a level of extension (E) of the output shaft with respect to the housing, such that the position of the output end of the output shaft may be determined.

A feces collection assembly for collecting feces from a variety of surfaces includes a pair of tongs that are each manipulated thereby facilitating the tongs to selectively grasp feces on a surface. The tongs have a plurality of gripping edges and each of the gripping edges has a unique structure with respect to each other. Each of the gripping edges engages the feces on selected variety of support surfaces. In this way the feces may be removed from a variety of support surfaces.

A long-shaft tool includes a shaft extending along a longitudinal axis and having a handle at a first end of the shaft and a second end opposite the first end with a holder for a manipulator wherein the holder has a protruding latch pin provided for engagement with a recess of a manipulator, which can be moved from the protruding position into a retracted position. The holder has a coupling half for coupling with a coupling half of a manipulator which is rotatable relative to a base body of the shaft.

The present invention relates to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and the pliers stick and, more specifically, to a manual hydraulic multi-functional extra-high-voltage insulating gear gripper pliers stick for live-wire work and an indirect live-wire construction method using the pliers stick, which: allow components or the like, which are installed on and removed from an electric pole in order to perform electric wire-stringing work or fix electric wires, to be remotely constructed by means of the indirect live-wire work while maintaining a safe distance from live wires when constructing power distribution equipment in an extra-high-voltage live-wire state; ensure safety by eliminating risks due to instability during work, said instability occurring due to the intensity of the labor and the physical limitations of the workers; and bring about improvements in utilization efficiency.

A wire pulling grip includes a main body, at least one cable-engaging jaw connected to the main body, and at least one cable-engaging surface included on the at least one cable-engaging jaw. A coating is disposed at least partially along the at least one cable-engaging surface, the coating including a plurality of surface protrusions arranged and configured to plastically deform an elastic cable jacket without slipping or tearing when a cable having the elastic cable jacket is engaged by the at least one cable-engaging jaw.
