SLOT FLAT ROTARY ANGLE GAUGE

The utility model relates to a notched flat rotary angle gauge, belonging to a forestry measuring instrument, namely a tool for measuring growing stock of forest land. The utility model is improved on the basis of a bar type angle gauge; the bar body is made into two sections which are connected by a hinge, so the utility model can be folded. One end of the bar body is provided with a notched board which is vertically erected on the surface of the bar by a bearing. The notched board can be shifted by a gravity shifting needle and be rotated freely. The rotation amount of the notched board is consistent with slope. The notched flat rotary angle gauge can correct slope angle rapidly and has the advantages of small size, light weight, easy manufacture and convenient carrying. The utility model is a measuring instrument which is welcomed by forestry technical personnel.
