Hammering safety fixture for hand protection

A hammering aid that secures nails and expands the striking surface to prevent finger injuries.

This technology is a hammering fixture featuring a cylindrical support body with a nail insertion hole and a larger gripping member to hold the nail upright, along with a cap member that covers the support to provide a wider striking surface. The sidewalls of the cap member are coupled to a base plate via interlocking grooved connectors.

Hammering thin nails while holding them with your fingers is difficult due to the small nail head, often leading to accidents where the hammer strikes the fingers. Additionally, the initial strike frequently misses, causing the nail to bend.

This technology uses a ball screw to tighten a semi-cylindrical support body, allowing it to be adjusted to fit various nail sizes and types. It also includes internal shock-absorbing and height-adjustment components to manage impact and nail length. Suitable for interior construction, furniture assembly, and DIY tools, it enables beginners to drive nails straight without risking hand injuries.

Key Features:

• A nail-securing member consisting of a cylindrical support body of a certain height with a nail insertion hole at the center, and a gripping member with a larger outer diameter at the bottom.
• A cap member that covers the top of the support body to expand the hammer's striking area, composed of a base plate and four sidewalls, with an opening at the bottom.
• A connecting member where the ridges and grooves on both sides of a rod-shaped body attached to the sidewalls interlock with the concave and convex parts inside the base plate.
• A movement adjustment member that uses opposing threaded moving blocks and a ball screw to adjust the gap between the split semi-cylindrical first and second support bodies.
