The invention provides a special tool used for pulling out latterly-planted trees. According to the technical scheme, the special tool comprises an operation rod. A handle is arranged at one end of the operation rod. A supporting plate making contact with the ground is fixed to the other end of the operation rod. The included angle formed between the plane where the supporting plate is located and the axis of the operation rod ranges from 100 degrees to 150 degrees. A tree clamping mechanism is in sliding connection with the operation rod and comprises a clamping base used for tightly clamping latterly-planted trees. An opening is formed in one side of the clamping base and provided with a clamping lock. The tree clamping mechanism is used for tightly clamping latterly-planted trees at first, then the operation rod is rotated upwards, and therefore the latterly-planted trees can be pulled out. The special tool is convenient to use, easy to operate in a labor-saving mode and high in latterly-planted tree pulling-out efficiency, and well protects tree bark against damage.
