Tensile rod and bracket

A tensile rod, comprising:

• a first pulling rod;
• a second pulling rod comprising a pulling end and an inserting end that are opposite to each other, and the inserting end of the second pulling rod being removably interposed in the first pulling rod;
• and
• an extruding assembly comprising:
• a first friction seat comprising a first connecting arm;
• a second friction seat comprising a second connecting arm at a position corresponding to the first connecting arm, the second friction seat and the first friction seat being enclosed to form a sleeve, the sleeve being sleeved at the inserting end of the second pulling rod and being located between the first pulling rod and the second pulling rod;
• the first connecting arm and the second connecting arm are coupled together by a fastener, wherein the fastener comprises screw;
• a rivet;
• or the rivet and hot melt connection;
• and an elastic member sleeved over the first connecting arm and the second connecting arm;
• wherein the extruding assembly abuts against an inner wall of the first pulling rod, two first connecting arms and two second connecting arms are both provided to form two sets of the extruding columns, and the elastic member is arranged on each of the extruding columns;
• and the extruding assembly is configured to provide a uniform extruding friction force from the inserting end of the second pulling rod to the inner wall of the first pulling rod.
