The invention discloses a dragging mechanism which comprises a vehicle body, a frontward movement cylinder, an oil cylinder connection base, a tray, push-pull rods, poking rod assemblies and poking rod supports. The bottom of the vehicle body is provided with a supporting beam, and the front of the vehicle body is provided with the tray. The rear end of the reverse face of the tray is provided with a main beam. The two sides of the middle are symmetrically provided with the poking rod supports. The middle of the main beam is provided with a first through hole. One end of the frontward movement cylinder is connected with the supporting beam. A piston rod is connected with the oil cylinder connection base. The poking rod assemblies are formed by welding poking rod cylinders, poking rods and rotating lugs. The two sides of the oil cylinder connection base are connected with one ends of the push-pull rods in a hinged mode. The other ends of the push-pull rods are connected with the rotating lugs in a hinged mode. One end of each poking rod is connected with the corresponding poking rod support in a hinged mode. According to the dragging mechanism, a piston rod of the frontward movement cylinder is adopted to stretch out and draw back so as to indirectly drive the poking rod assemblies on the two sides to be opened or closed, two wheels of a vehicle can be hooked in the process that the poking rod assemblies are closed and opened, and dragging of the vehicle is achieved.
