S 3 : under the action of a telescopic spring (373)The limiting inserting column (35) is quickly buckled to an inner cavity of the limiting barrel (22), and then the limiting barrel (22) is used for limiting the limiting inserting column (35);
S 4 : when the steel truss bears the weight, the load is buffered through the elastic rubber buffer column (54) in the inner cavity of the outer sleeve (50).
