Bed angular surveying appearance

The utility model provides a bed angular surveying appearance, including the installation department, be equipped with angle identification portion on the installation department, the main shaft setsfirmly in installation department middle part position to perpendicular to angle identification portion sets up, the owner pointer rotates and locates on the main shaft to remain vertical state throughout under the action of gravity, supplementary pointer has the rotation around the main shaft, under external force, but assists arbitrary position of pointer pointing angle identification part and keeps static. The utility model discloses bed angular surveying appearance, when the bed rotated, angle identification portion, installation department and main shaft rotated along with the bed, and the owner pointer keeps vertical state under the effect of gravity ball, and then can read the angle value when the external crucible according to the scale interval that the owner pointer was indicateed, bed angle that this be
