Spanners TRIZ Cases
- Flexible Magnetic Wrench Holder for Curved Surfaces
Elastomeric strips with segmented magnets resolve the trade-off between rigid structure stability and adaptability to curved ferrous surfaces.
- Power Tool Handle Clamping Mechanism for Drop Damage Prevention
Interlocking protrusions and grooves on a secondary handle distribute clamping force to prevent housing damage during drops or over-tightening.
- Spark Plug Ground Electrode Shield Removal Tool
A threaded rod and hollow tube tool extracts broken spark plug ground electrode shields from engine cylinder heads.
- Three-Jaw Wrench Head for Confined Space Torque Measurement
Serial pivotable jaws enable lateral engagement of tube-nuts in confined spaces, preventing fastener deformation during torque measurement.
- Dual-Sided Wrench Combining Crescent and Pipe Tools
A dual-sided wrench device merges an adjustable crescent wrench with a pipe grip on a single handle for rapid tool switching.
- Angled Cutting Body Steel Strapping Tool Hook Block
An angled cutting body and upward moving hook block resolve the contradiction between secure fastening and difficult strap separation in steel strapping tools.
- Torque Tool Release Mechanism with Eccentric Bearing Pins
Eccentric bearing pins adjust release lever positioning to eliminate component sorting and reduce production time.
- Co-centric Pin Spanner Torque Alignment
Aligning drive and pivot axes prevents torque magnification at non-90 degree angles, eliminating pin lift and stabilizing engagement.
- Foldable Torque Tool With Rotating Driving Member And Blocking Structure
A foldable torque tool uses a rotatable driving member and blocking structure to enable compact storage.
- Powdered Metal Tool Bit Wear Resistance
Uniform carbide distribution in powdered metal tool bits overcomes wear resistance limits of conventional steel.
- Ratchet Connector Design for High Torque and Easy Assembly
Integrated ratchet connector with a control ring enables unidirectional movement.
- Auxiliary Handle for Hex Wrenches With Adjustable Mounting Slots
Rotating stem with multiple mounting slots and flat spring secures hex wrenches of varying sizes, eliminating wobble without requiring separate tools.
- Wrench Driving Surface Notches for Rounding Fasteners
Segmented wrench jaws with notched contact portions bite rounded fastener corners to prevent marring.
- Pivot Head Wrenching Tool Torsion Spring Retention
Replacing linear springs with a torsion spring anchored to the handle eliminates fatigue while maintaining precise pawl engagement for reliable retention.
- Torque Wrench Lock Device with Nested Self-Service Mechanism
Nested locking sleeves and self-service biasing prevent accidental torque limit adjustments while polygonal features reduce friction during setting.
