Portable Handheld Shearing Machines TRIZ Cases

Palm and finger handle geometry with flanges, a compound hinge, and relief washers reduces exertion, pinching, and cutting friction.

A rotatable cutting sleeve switches between matched openings for different wire diameters, cutting changeover time, space use, and cost.

Plate-like limb extensions support both sides of the joint to stop twisting and jamming during high-force cutting, enabling cleaner cuts.

Transverse blade spacing near cut completion prevents cable-harness jamming and helps motor-operated shears return smoothly to home position.

Dual-plane limb support, a penetration slot, and a stop pin keep shear edges aligned for clean cuts under high shearing force.

An eccentric rotating blade and clamp assembly cuts post-tensioning cables in tight anchor spaces without threading, improving safety and speed.

Transverse blade spreading at the end of the cut prevents material clamping and lets motor-operated shears return reliably to home position.

Fiber-reinforced composite jaws and hollow handles reduce bolt cutter weight, while hardened blades and damping plugs help maintain cutting alignment.

A hinged second frame and trip lever open the cutting zone for easier wire or pipe insertion while preserving precise, safer guillotine cutting.
