Pure mechanical type heavy landing indication structure

A pure mechanical type heavy landing indication structure includes a landing gear buffer supporting pillar, a bracket and a cutter; an indication wire is mounted on the bracket, the bracket is fixed on the upper end of the landing gear buffer supporting pillar, a cutter bracket is mounted on the lower end of the landing gear buffer supporting pillar, and the cutter used for cutting the indicationwire is mounted on the cutter bracket; the upper end of the landing gear buffer supporting pillar is a fixed end, and the lower end of the landing gear buffer supporting pillar is a movable end; whenan aircraft lands normally, the cutter cannot collide with the indication wire, and when a heavy landing occurs, the cutter crushes into the bracket equipped with the indication wire and cuts off theindication wire; the heavy landing indication structure does not require support of additional power, air supply, hydraulic pressure, and the like, as long as appropriate adjustment is performed on astructure of a connection pa
