Hot Stick Adapter with Movable Hook for Dielectric Cover Installation

The patent applies the dynamics principle by making the hook movable relative to the hot stick body. The hook can extend beyond the work end of the hot stick and retract into it, allowing dynamic adjustment of the hook's position and reach. This enables the hook to access holes in dielectric covers that are positioned at various distances from the hot stick, improving gripping capability without requiring multiple fixed-length hooks.

The patent segments the hot stick system into distinct functional components: the hot stick body, the movable hook, and the actuation mechanism. This segmentation allows each component to be optimized independently - the hook for gripping, the body for structural support, and the actuation mechanism for controlling hook movement. It also enables the hook to be replaced or adjusted without replacing the entire hot stick.

The hook is designed to be dynamically movable between an extended position (for reaching distant holes) and a retracted position (for storage and safety). The actuation mechanism allows the operator to control the hook's position, extending it when needed to access holes at various distances and retracting it when not in use. This dynamic positioning capability provides both extended reach and adaptability.

The patent introduces an intermediary actuation mechanism (such as a cable, rod, or linkage system) that transmits the operator's input from the handle end of the hot stick to the hook at the work end. This intermediary allows the operator to control the hook's extension and retraction from a safe distance, enabling position adjustment without direct contact with the hook itself.

The patent implements a universal tool mounting interface on the hot stick that can accommodate various types of tools for different functions. The mounting structure includes standardized features (such as slots, holes, or attachment points) that allow single-purpose tools like hole saws, fasteners, or positioning devices to be attached and removed as needed. This enables one hot stick to perform multiple functions by simply changing the attached tool.

The tool mounting system is segmented into the hot stick body and interchangeable tool components. This segmentation allows tools to be independently selected and attached based on the specific task at hand, while the hot stick body remains a constant platform. The modular design simplifies the mounting structure by using standardized interfaces rather than custom-integrated tools.

The hot stick itself serves as an intermediary tool that allows the operator to manipulate dielectric covers from a safe distance. The long insulated shaft transmits the operator's movements and forces to the hook and attached tools at the work end, enabling precise manipulation without the operator needing to be close to the electrical equipment. This maintains both safety and operational precision.

The patent extends the operational dimension by using a long insulated shaft, allowing the operator to work from a different spatial position (further away from the electrical equipment) while still achieving the necessary manipulation precision. The lever assembly and mechanical linkages transmit movements efficiently over the length of the shaft, maintaining control precision despite the increased distance.
