Abstract: A trampoline with improved hooking structure includes a first annular member, legs, a second annular member, and elastic units. The legs has end fixed to the first annular member. The second annular member is larger than the first annular member and is coupled to the legs and is arranged below the first annular member. The elastic units each include a connection ring attached to an elastic mat, a brace element, and an elastic element. The brace element has a projection end pivoted to the first annular member and two opposite end respectively pivoted to first and second joint members. The first joint member has an opposite end coupled to the connection ring to set the elastic mat within the first annular member. The second joint member has an opposite end coupled to the elastic element and an opposite end of the elastic element is attached to the second annular member.
