Disclosed is a fishing device for a probe of a clinometer. The fishing device is characterized by comprising a fishing casing; a pulley groove is formed in the side of the fishing casing upwards fromthe lower edge in the axis direction; the upper end of the pulley groove is provided with an upper reserved connector, and a lower reserved connector is formed in the position, close to the lower edgeof the fishing casing, of the pulley groove; another pulley groove which is the same as the pulley groove and is provided with an upper reserved connector and a lower reserved connector is formed inthe opposite side of the pulley groove, and the diameters of the upper reserved connectors and the lower reserved connectors of the two pulley grooves are larger than the diameter of a pulley of the clinometer fished by the fishing device; and a steel cable hole is formed in the top of the of the fishing casing. Obviously, the fishing device for the probe of the clinometer is simple in structure,low in cost, convenient to manufacture and use and good in use effect; the problem that the probe of the clinometer is difficult to sleeve with the fishing casing when stuck can be effectively solved;by forming the pulley grooves, the probe of the clinometer can enter the fishing casing smoothly, then the casing is rotated and pulled upwards, and the probe of the clinometer can be inside the fishing casing.
