Nail Extractors TRIZ Cases

A guarded multi-strike tack strip tool protects fingers during floor-level nailing and reaches toe kick recesses while reducing tool changes.

A guided hollow tube and electric linear drive stabilize the claw mechanism for reliable removal of long railroad spikes with easier handling.

A guided hollow tube and direct claw connection improve railroad spike pulling stability, stroke height, and handling for track maintenance.

A rotating removal unit and paper pressing mechanism lift staple crowns stably across paper types while keeping the remover compact.

Spring-biased fingers grip nail heads securely to remove embedded nails with less force, less surface damage, and optional drill or robot use.

A ratcheted lever tool pushes and locks the spring push into the housing, improving optical connector assembly precision and reducing rework.

A nail gun attachment uses an extraction pin to grip the nail point and pull out protruding nails when the head is inaccessible.

Repeated insertion-part reciprocation lowers pullout resistance, enabling complete staple removal from thick, rigid sheet bundles.

An onboard battery, motor control circuit, and pull-rod sensing replace hydraulic hoses while reducing fatigue and speeding railroad spike removal.

Spring-biased fingers grip nail heads through a tube, reducing manual force and helping remove nails without damaging surrounding material.

Vertical motor placement utilizes empty space during operation to reduce device height and width dimensions without adding guiding mechanisms.

A patch deployment device uses a U-shaped connection clip to reversibly attach and detach surgical patches during laparoscopic procedures.
