         3 . The safety trampoline according to  claim 1 , wherein the elastic protective sleeve is an elastic meshed fabric with the plurality of net holes throughout. 
     
     
         4 . The safety trampoline according to  claim 1 , wherein the plurality of connecting rings are triangular rings. 
     
     
         5 . The safety trampoline according to  claim 1 , wherein the edge of the second end of the elastic protective sleeve located at the bottom of the trampoline frame is tied through a pulling rope movably penetrating through a periphery of the elastic protective sleeve. 
     
     
         6 . The safety trampoline according to  claim 1 , wherein the edge of the second end of the elastic protective sleeve located at the bottom of the trampoline frame is tied through an elastic belt connected to a periphery of the elastic protective sleeve. 
     
     
         7 . The safety trampoline according to  claim 1 , wherein a first hook is formed at a first end of each of the plurality of springs, a second hook is formed at a second end of each of the plurality of springs, a hanging hole for connecting each of the plurality of springs is formed in the trampoline frame, the first hook is connected to the hanging hole, and the second hook is connected to each of the plurality of connecting rings. 
     
     
         8 . The safety trampoline according to  claim 1 , wherein each of the plurality of connecting rings is connected to the jumping mat through a connecting fabric sleeve passing around each of the plurality of connecting rings. 
     
     
         9 . The safety trampoline according to  claim 1 , wherein the trampoline supporting legs are detachably connected to the bottom of the trampoline frame, and an avoidance channel for the trampoline supporting legs to pass through is formed in the elastic protective sleeve and/or a trampoline pad. 
     
     
         10 . The safety trampoline according to  claim 2 , wherein the trampoline frame is movably embedded on the trampoline supporting legs. 
     
     
         11 . The safety trampoline according to  claim 3 , wherein the edge of the second end of the elastic protective sleeve located at the bottom of the trampoline frame is tied through a pulling rope movably penetrating through a periphery of the elastic protective sleeve. 
     
     
         12 . The safety trampoline according to  claim 3 , wherein the edge of the second end of the elastic protective sleeve located at the bottom of the trampoline frame is tied through an elastic belt connected to a periphery of the elastic protective sleeve.
