The utility model discloses an inclined laser range finder, which comprises a base, a laser range finder and an angle plate, the angle plate is arranged at the upper end of the base and perpendicularto the base, the angle plate comprises a circle center end and an arc-shaped end, and angle scale marks are marked at the arc-shaped end; the laser range finder comprises a hinge end and a free end; the hinged end is vertical to the angle plate and is hinged with the circle center end of the angle plate; the free end points to the arc-shaped end, and the laser range finder rotates in a vertical plane with the hinged end as the circle center. The utility model provides an inclined laser range finder. The laser range finder is obliquely arranged and used in cooperation with the angle plate, theoblique distance between the power transmission line and the laser range finder can be measured obliquely below the power transmission line, then the vertical distance between the power transmission line and the ground is obtained through angle calculation, when the height of the power transmission line is measured in this way, measuring personnel do not need to be located below the power transmission line any more, and more use environments can be adapted.
