Unilateral displacement modulus formula telescoping device stiff end structure

The utility model relates to an unilateral displacement modulus formula telescoping device stiff end structure, including compressing tightly supporting assembly, pressure -bearing supporting assembly, supporting case subassembly and supporting beam subassembly, it fixes on supporting case subassembly upper portion to compress tightly supporting assembly, pressure -bearing supporting assembly fixes in supporting case subassembly lower part, the supporting beam subassembly is placed in supporting case subassembly, has placed the stopper between supporting beam subassembly and the supporting case subassembly, the fixed axle passes the through -hole in the middle of supporting case subassembly, stopper, the supporting beam subassembly, be equipped with the gland in supporting case subassemblyboth sides, in the axle sleeve embedding gland, on the gland and the axle sleeve embedding fixed axle both sides shaft shoulder. Stable connection the through between each part originally can reach connection, shock attenuat
