description The utility model discloses an umbrella type fence support. A middle sliding block and a lower sliding block are used for driving three sets of supporting units to be unfolded and folded. By utilizing a compression spring and matching with the driving of a bidirectional lead screw to a middle sliding block, the three groups of supporting units in a folded state can continuously move upwards along with the middle sliding block and a lower sliding block and completely enter a connecting sleeve; the lower sliding block can move downwards along with the middle sliding block and the lower sliding block to abut against a lower mounting base of the lead screw mounting frame, the middle sliding block continues to move downwards, the springs are overcome, and the three sets of supporting units are unfolded. And the telescopic part for mounting the fence warning tape is matched with the upper thread part of the two-way screw rod, so that the length of the folded umbrella type fence bracket is reduced.
