3. when the diameter of the metal steel pipe is larger, the arc length of the inner ring of the metal steel pipe is larger, because the detection rod is positioned at the axial position of the metal steel pipe, therefore, the longer the time for the longitudinal detector on the detection rod to detect one circle of the inner side of the metal steel pipe is, in order to ensure that the longitudinal detector can completely and completely detect the whole inner ring of the metal steel pipe, the axial moving speed of the detecting rod or the longitudinal detector needs to be controlled, the moving speed cannot be too high, otherwise, the problems of a detecting blind area or an incomplete detecting surface can occur, and similarly, when the diameter of the metal steel pipe is smaller, the first speed regulating gear is selected to be meshed with the fourth transmission gear, thereby the axial displacement speed of the detection rod is improved, the function of automatically adjusting the displacement speed of the detection rod according to different diameters of the metal steel pipe is realized, the accuracy of a detection result is improved, and the detection work efficiency is improved.

and 3, the adjusting component 6 achieves the purpose of driving the fifth transmission gear 171 to rotate by selecting one of the first speed regulating gear 42, the second speed regulating gear 43 and the third speed regulating gear 44 to be meshed with the third transmission gear 41, the rotating fifth transmission gear 171 achieves the purpose of adjusting the axial moving speed of the detecting component 5 according to the diameter of the metal steel pipe by being meshed with the detecting component 5, when the diameter of the metal steel pipe is larger, the larger diameter one of the first speed regulating gear 42, the second speed regulating gear 43 and the third speed regulating gear 44 is selected to be meshed with the third transmission gear 41, and when the diameter of the metal steel pipe is smaller, the smaller diameter one of the first speed regulating gear 42, the second speed regulating gear 43 and the third speed regulating gear 44 is selected to be meshed with the third transmission gear 41, so that the purpose of improving the detecting efficiency is achieved.
When the invention is used, the installation links of the metal steel pipe are as follows: the first conductive frame 62 and the first electromagnet 63 are powered off by controlling the power supply 61, the first electromagnet 63 loses the adsorption force on the first magnet block 23 after the power off, at this time, the elastic force of the second return spring 24 can drive the first shell 21 to do linear motion, and the first electromagnet 63 stops until the meshing teeth 25 move to the position meshed with the second transmission gear 37, and the design of the mutual matching of the limiting ribs 22 and the limiting grooves 141 enables the first shell 21 not to rotate, therefore, when the driving part 12 drives the second shell 31 to rotate through the first transmission gear 32, the first threaded pipe 36 can rotate around the axis thereof by utilizing the meshing between the meshing teeth 25 and the second transmission gear 37, the rotating first threaded pipe 36 drives the plurality of clamping blocks 33 to do radial motion in the first mounting hole 14 through the first threaded rod 34, thereby achieving the purpose of adjusting the self caliber according to the diameter of the metal steel pipe, the method has the characteristics of convenient operation and wide application range;
after the metal steel pipe is fixed, one of the three conductive switches 69 is controlled to be electrified through the control panel 13, when the diameter of the metal steel pipe is larger, the second electromagnet 68 corresponding to the third speed regulating gear 44 is electrified through the conductive switch 69, an adsorption force is generated between the electrified second electromagnet 68 and the second magnet block 45, the adsorption force overcomes the elastic force of the first return spring 19 to drive the third speed regulating gear 44 to move, when the third speed regulating gear 44 moves to a position meshed with the third transmission gear 41, the third speed regulating gear stops, at the moment, the first conductive frame 62 and the first electromagnet 63 are electrified through the control power supply 61, an adsorption force is generated between the electrified first electromagnet 63 and the first magnet block 23, the adsorption force achieves the purpose of driving the meshing teeth 25 to be separated from the second transmission gear 37 in a mode of overcoming the elastic force of the second return spring 24, and the metal steel pipe is clamped by the clamping part 3, thus, the driving part 12 can not only drive the metal steel pipe to rotate through the clamping part 3, but the rotating clamping part 3 can also drive the detection rod 55 to insert into the rotating metal steel pipe through the third transmission gear 41, one of the three speed-regulating gears (the first speed-regulating gear 42, the second speed-regulating gear 43 and the third speed-regulating gear 44), the fifth transmission gear 171, the fourth transmission gear 52, the second threaded pipe 51 and the second threaded rod 53, because the driving part 12 drives the metal steel pipe to rotate at a constant speed, i.e. an constant angular velocity, when the diameter of the metal steel pipe is larger, the arc length of the inner ring of the metal steel pipe is larger, and because the detection rod 55 is located at the axial position of the metal steel pipe, the time taken by the longitudinal detector on the detection rod 55 to detect the inner side of the metal steel pipe for one turn is longer, in order to ensure that the longitudinal detector can completely detect the whole inner ring of the metal steel pipe, the axial moving speed of the detecting rod 55 or the longitudinal detector needs to be controlled, the moving speed cannot be too high, otherwise, the problem of a detection blind area or incomplete detection surface can occur, similarly, when the diameter of the metal steel pipe is smaller, the first speed regulating gear 42 is selected, the first speed regulating gear 42 is meshed with the fourth transmission gear 52 through the fifth transmission gear 171, the axial moving speed of the detecting rod 55 is improved, the function of automatically adjusting the moving speed of the detecting rod 55 according to different diameters of the metal steel pipe is achieved, the accuracy of a detection result is improved, and the detection working efficiency is improved.
