Description

Technical Field

[0001] The utility model relates to the technical field of electrician tools, in particular to a handle and a screwdriver. Background Art

[0002] Electrical tools play an indispensable role in daily life and work, greatly facilitating electrical installation and equipment maintenance. With technological advancements and a growing demand for more versatile tools, screwdrivers with a voltage test function are now a common multifunctional electrical tool. These screwdrivers not only retain the basic functionality of a traditional screwdriver—tightening and loosening screws—but also incorporate a voltage test function, allowing operators to monitor circuit status in real time while performing electrical work, significantly improving both efficiency and safety.

[0003] The display module of this screwdriver is typically located in the middle of the handle. In practice, when the operator holds the handle, the display module can easily be obscured. This is especially true when working in a confined space. This prevents the operator from seeing the information on the display module, hampering their judgment. Accurately judging circuit status is crucial during electrical work. If the operator misjudges the circuit status due to an obstructed display module, it can lead to serious safety accidents and threaten the operator's life. Utility Model Content
