Problems solved by technology

[0002] Among all kinds of fire rescue tools, many rescue tools are hydraulic rescue tools, but hydraulic rescue tools cannot fully adapt to the environmental requirements in some cases, and are forced to cut objects in many cases, but when cutting It will cause further harm to the victim, so we designed this two-way magnetic levitation reverse pull rescue tool to replace the existing cutting tool

Abstract

The invention discloses a break-in tool with two sides outwardly stretchable simultaneously and multiple permanent magnet pressure structures. The break-in tool mainly comprises two large magnetic rings, a barb, a small movable magnetic ring, a frame shell and the like. The large magnetic rings are fixed at two ends of the frame shell. The small movable magnetic ring is nested in a clearance between the symmetrical large magnetic rings. The small movable magnetic ring is opposite to the large magnetic rings arranged on concentric position in magnetizing directions. The barb is arranged at the rear of the small movable magnetic ring.

Description

Technical field [0001] The invention relates to a dismantling machine that stretches outward simultaneously on both sides of a plurality of permanent magnet pressure structures. The device is based on a metal support frame, and two ring-shaped permanent magnet blocks are fixed at both ends with a gap in the middle, and then A corresponding magnetic block is installed in the gap to make it complement each other, and anti-pull barbs are installed on the outside of the small magnetic block, and the two sides are symmetrical. belongs to the field of tools. Background technique [0002] Among all kinds of fire rescue tools, many rescue tools are hydraulic rescue tools, but hydraulic rescue tools cannot fully adapt to the environmental requirements in some cases, and are forced to cut objects in many cases, but when cutting It will cause further harm to the victim, so we designed this two-way magnetic levitation reverse pull rescue tool to replace the existing cutting tool.
