safer, can be matched with springs or elastic ropes to form relative tensioning compensation when the springs or the elastic ropes become soft along with the use of the trampoline, is more practical, and comprises a top protection frame, a bottom mounting frame and an interaction terminal, the bottom mounting frame is fixedly connected with a plurality of trampoline supporting legs, and the interaction terminal is connected with the trampoline supporting legs. A compensation
system is installed on the bottom installation frame, a plurality of elastic pieces are connected into the compensation
system, the elastic pieces are connected with elastic
jumping cloth, a follow-up line is arranged on the bottom face of the elastic
jumping cloth, a plurality of vertical
assembly rods are detachably installed on the bottom installation frame, and the vertical
