The utility model provides a transport vechicle traction lever, its characterized in that, this traction lever contains the cross-section and is square traction tube and stand pipe, and the front end of traction tube is equipped with the traction hole, and the rear end of traction tube is a fork ear structure, is equipped with coaxial heterotypic hole on the both sides auricle of fork ear, and this heterotypic hole is formed by slotted hole and circular port complex, and the distance between the auricle of both sides of fork ear is greater than the cross-section width of stand pipe, the end both sides of stand pipe be equipped with coaxial slotted hole, this slotted hole length direction perpendicular to axial of stand pipe, traction tube and stand pipe are articulated through a connecting axle, and the axis body cross-section of this connecting axle matches with the slotted hole of stand pipe end, and the axis body cross-section of connecting axle matches simultaneously with the heterotypic hole on the traction tube fork ear.

The fork ear of traction tube cup joints the front end at the stand pipe, and the circular port in special-shaped hole on the fork ear auricle keeps away from the traction tube, and the length direction of the slotted hole in special-shaped hole is the same with the axial of traction tube.

When the traction tube is perpendicular to the guide tube, two ends of the connecting shaft are located at the positions of the long round holes of the special-shaped holes, and when the traction tube and the guide tube are in the same direction, two ends of the connecting shaft are located at the positions of the round holes of the special-shaped holes.

The beneficial effect of this application lies in: the traction rod structure is in a horizontal state when in a working state, can be vertically locked when in a non-working state, can effectively reduce the occupied space of a transport vehicle when in use and parking, increases the space utilization rate of a factory building, and can only be rotated around a connecting shaft by vertically and upwards lifting the traction rod, so that the potential safety hazard caused by unstable vertical placement of the traction rod is eliminated.

The present application will be described in further detail with reference to the accompanying drawings.
