By adjusting the position of the hinge connection mechanism 2 in the well and its own angle, when encountering an obstacle, it can be adjusted so that the upper joint 1 of the logging instrument, the hinge connection mechanism 2 and the lower joint 3 of the logging instrument have a certain angle, so that the hinge connection mechanism 2 drives the lower joint 3 of the logging instrument, and the lower joint 3 of the logging instrument drives the probe of the logging instrument to always contact the well wall for easy detection and use.
[0029] Among them, when installing several chain plates 4, a movable mechanism 10 is installed at the connection between two adjacent chain plates 4, so that the two sides of the movable mechanism 10 are located in the second mounting hole 9 of the second hinged plate 8, and the middle position of the movable mechanism 10 is installed in the first mounting hole 7 of the first hinged plate 6, so that rotation can be generated between the two adjacent chain plates 4, and the traction rope 12 is adjusted through the adjustment mechanism 15, so that when the traction rope 12 moves along the traction seat 11, it will drive the limit block 13, the limit block 13 will drive the traction seat 11, and the traction seat 11 will drive the connected chain plate 4 to rotate, so that it can be adjusted and used after encountering obstacles.
