The left and right ends of the slide rod at the lower end of the safety net are respectively placed in the slide grooves of the two fixed frames; the left and right ends of the slide rod located in the slide grooves of the two fixed frames are fixed with iron blocks.

[0007] A reel transmission mechanism is arranged in a mounting cavity of a fixed frame, and the reel transmission mechanism comprises a driving bevel gear and a driven bevel gear, and the driving bevel gear and the driven bevel gear are meshed, wherein the driven bevel gear is fixed to the end of the reel located in the mounting cavity, the driving shaft extends from the outside of the fixed frame into the mounting cavity of the fixed frame, the driving shaft is rotatably connected with the fixed frame, the driving bevel gear is fixed to the inner end of the driving shaft located in the mounting cavity, and the rotating handle is fixed to the outer end of the driving shaft located outside the fixed frame.

[0008] A connecting column extending upward is fixed on the upper end surface of each fixing frame, and a threaded hole is provided on the connecting column; a connecting groove recessed into the interior of the fixing frame is provided on the lower end surface of each fixing frame, and the connecting groove is adapted to the specification and size of the connecting column, and a threaded hole connected to the connecting groove is provided on the fixing frame, and the threaded hole on the fixing frame corresponds to the position of the threaded hole on the connecting column.

[0009] The advantages of the utility model are that the safety net wound on the reel can be rolled up by rotating the rotating transmission reel of the rotating handle after use, thereby realizing the quick storage of the safety net, thereby avoiding the problem of dirt or collision damage in the external fixing frame; and after the safety net is opened and rolled up, the sliding rod at the bottom can be adsorbed by the top and bottom magnetic blocks in the slide groove, thereby ensuring the stability of the safety net after opening and rolling up.

[0010] The connecting columns and connecting grooves provided at the upper and lower ends of the fixing frame, and the screws fixedly installed between the connecting columns and the connecting grooves, can also enable the external fixing frame to be assembled quickly as a whole, and ensure the strength and stability of the connection after assembly.
