The utility model relates to the technical field of door and window deformed steel, and discloses high-toughness door and window deformed steel convenient to mount and dismount, which comprises two vertical deformed steel bars and two transverse deformed steel bars, connecting steel bars are hinged to the opposite sides of the two vertical deformed steel bars, and the transverse deformed steel bars are hinged to the opposite sides of the two vertical deformed steel bars. Threaded holes are formed in the front side and the rear side of the transverse special-shaped steel bar. According to the high-toughness door and window deformed steel convenient to mount and dismount, the left end and the right end of a transverse deformed steel bar are placed into inserting grooves in two attribute deformed steel bars correspondingly, then a connecting steel bar is rotated, so that a connecting hole corresponds to a threaded hole in position, and then a rotary knob is rotated; the screw rod can be driven to rotate in the t
