The invention relates to a flexible and convenient track and field hurdle. The flexible and convenient track and field hurdle comprises two hurdle columns, a hurdle transverse rod, a hurdle bottom pillar and supporting pillars, the hurdle transverse rod is installed between the upper ends of the two hurdle columns, the hurdle bottom pillar is installed between the lower ends of the two hurdle columns, and each supporting pillar is installed at the left end of the corresponding hurdle column; each hurdle column comprises the corresponding supporting pillar, a moving pillar, telescopic clampingteeth, a clamping tooth spring, a limiting clamping plate, a limiting connecting pillar, a tilting prevention mechanism, a pushing mechanism, a limiting spring and a pressing shelf. By means of the flexible and convenient track and field hurdle, the problems can be solved that when an existing hurdle is in use, the height and length of the hurdle cannot be adjusted, the hurdle cannot be conveniently moved, the hurdle may be deformed when falling off, and the hidden safety hazard that people may get hurt when the hurdle falls off exists; the height and length of the hurdle can be adjusted, andthe hurdle can be conveniently moved.
