A single-ball, spring-loaded coupling simplifies removable tool head locking while improving one-handed use, feedback, and reliability.

A fan-driven extractor with an oblique filter and sealed tool connection improves drilling dust capture, limits air leakage, and stays compact.

Color-changing metal detection on a handheld power tool warns of rebar before drilling and can block operation to avoid damage and injury.

A spring-loaded universal coupler replaces screws to speed chisel and needle scaler changes while keeping a stable air tool connection.

A flat spring keeps the retaining ball in place while a shorter sleeve and dual-bearing anvil support cut rattling and bit vibration.

A dual-stop sliding weight lets one tool handle hammering and pulling in tight spaces while reducing hand bruising from direct impact.

A concealed-stop slide hammer combines pulling and hammering with adjustable impact force, reducing hand injury risk in confined spaces.

Harvested impact energy powers a built-in counter that records cumulative strikes, helping users monitor tool fatigue life and rupture risk.

Separate spindle and piston drives let a rotary hammer tune rotation speed and blow frequency independently for more precise drilling.

A releasable locking component separates drilling rotation from sleeve expansion, enabling one-step anchor setting with stronger friction fit.

An integrated trough-shaped battery shield in a power tool suction accessory absorbs impact pulses and prevents battery pack damage.

A dual-channel coolant path swirls flow around the tool, improves heat removal, and prevents unintended cooling of the workpiece.

A flat spring shortens the sleeve and dual bearing support with an O-ring reduces anvil rattling and bit vibration in compact impact tools.

A collar and spring-biased retaining member lock larger tool bits securely while keeping the adapter compact for deeper drilling.

Learned motor-current signal shapes let hand-held power tools detect screw progress and shut off reliably without extra sensors.
