[0003] Infants and young children are lively and active. In order to avoid danger to infants and young children, some families will install fences to limit their range of movement. For example, Chinese utility model patent CN 202322781489.8 discloses a rolling shutter door fence, which includes a door fence frame assembly, and the door fence frame assembly is connected to a rotating mechanism that can rotate relative to it, and a rolling curtain that can be expanded or retracted is wound on the rotating mechanism. The rolling shutter door fence also includes a mounting seat that can be mounted on another wall, one end of the rolling curtain is connected to the rotating mechanism, and the other end is detachably connected to the mounting seat. A locking device that can lock the rotating mechanism is provided between the door fence frame assembly and the rotating mechanism. The locking device includes a plurality of locking positions provided on the rotating mechanism, and the door fence frame assembly is provided with a first sliding member that can slide up and down relative to it, and the first sliding member is provided with a locking portion that can be engaged in or disengaged from the locking position.
