Telescopic fence
The invention provides a telescopic fence. The telescopic fence comprises a telescopic fence body, two side rods and a limiting unit. The telescopic fence body comprises a first rod body set and a second rod body set; the first rod body set comprises a plurality of first rod bodies which are parallel to one another; the second rod body set comprises a plurality of second rod bodies which are parallel to one another; each second rod body and at least one first rod are arranged in a crossing manner; a parallelogram telescopic mechanism which can stretch out and draw back in the first direction is formed by the first rod body set and the second rod body set ; and the two side rods are connected with the two ends, in the first direction, of the telescopic fence body, and the extending direction of the side rods is perpendicular to the telescopic direction of the telescopic fence body. The limiting unit comprises a limiting rod, and the two ends of the limiting rod are detachably connected with the two side rods to limit stretching out and drawing back of the telescopic fence body. According to the technical scheme, the telescopic fence comprises the telescopic fence body, the two side rods and the limiting unit and solves the problem that in the prior art, the occupied space is large.
