The invention discloses a mechanical collision limiting device which is used for underwater mechanical equipment and comprises a shell, a limiting switch, a movable rod, an elastic piece and a self-rotating mechanism. The shell is provided with a trigger cavity and a buffer cavity; the limit switch is arranged in the trigger cavity; the movable rod sequentially penetrates into the buffer cavity and the trigger cavity in a sealed mode, the top end of the movable rod is used for stretching into the trigger cavity to push the movable end of the limiting switch, the bottom end of the movable rod is used for abutting against underwater mechanical equipment, and a limiting boss is arranged on the portion, located in the buffer cavity, of the movable rod and arranged on the peripheral face of the movable rod; one end of the elastic piece is connected to the top of the buffer cavity, and the other end of the elastic piece is connected to the limiting boss; the self-rotating mechanism is arranged in the shell, and when the movable rod moves in the axial direction, the self-rotating mechanism can drive the movable rod to rotate relative to the shell. According to the technical scheme, the use stability of the mechanical collision limiting device is improved.
