Background
In various drilling constructions on the ground, in order to accurately master the deviation between a drilling track and a designed track and provide a basis for correcting the deviation or preventing the deviation, the drilling at a certain depth needs to be subjected to inclination measurement. A gyro inclinometer (as shown in fig. 4) is a common inclinometer with high accuracy. When in inclination measurement, the sleeve in the drill hole is used for inclination measurement, and then a gyro inclinometer is put into the sleeve. The general gyro inclinometer moves in the casing in a mode of a probe tube and a pulley yoke, and the pulley yoke can keep the probe tube to be always coincided with the central line of the casing. Thereby ensuring the measurement accuracy and accuracy thereof. Sometimes, the object may drop into the sleeve carelessly in the measurement operation, and the object in the dropping sleeve may block the pulley yoke, so that the gyro inclinometer may be blocked in the sleeve (as shown in fig. 1), and is difficult to be smoothly lifted out of the borehole. The salvaging method generally adopts a conventional coring bit to carry out the extraction, and the cutting edge of the coring bit often simultaneously cuts an instrument and damages the instrument when the extraction is carried out; another salvaging method is to hook the pulley yoke by a hook for strong extraction, and usually salvage the gyro inclinometer for drilling after the pulley yoke is damaged. Both methods can cause the salvaged instruments to be seriously damaged or even scrapped. In addition, in the process of pulling out the sleeve from the drill hole, the gyro inclinometer falls off in the drill hole in the case of human misoperation.

Detailed Description
The present invention is further illustrated by the following specific examples, which should be construed as merely illustrative, and not limitative of the remainder of the disclosure.
When a shaft of a north wind well of a village mine in the original country is constructed for inspection drilling, in order to ensure the construction precision of drilling, a gyro inclinometer is adopted for inclination measurement. The type of the gyro inclinometer is CXY5, but during inclination measurement, a piece of rock accidentally falls in the sleeve, the gyro inclinometer is clamped in the sleeve, and the cable is lifted by the inclinometer to be difficult to pull out the inclinometer out of the hole. The fishing device of the invention is used for smoothly fishing out the gyro inclinometer and drilling holes.
