[0024] As Figures 1 to 4As shown, the middle part of the operating rod 14 is rotatably connected with the sleeve 2, the middle part of the sleeve 2 is fixedly connected with the fixed rod 21, the middle part of the operating rod 14 is fixedly connected with the fixed ring 22, the side wall of the fixed ring 22 is fixedly connected with the second limiting plate 23, the second limiting plate 23 is made of elastic material, the second limiting plate 23 and the sleeve 2 are arranged in ratchet cooperation, and the second limiting plate 23 plays the role of the pawl in the ratchet mechanism. During work, the bandage is wound around the middle part of the fixed rod 21, when it is needed to move the flaw detector body 1 to the middle part of the thinner pipeline, the bandage will become loose, and it is also difficult to tighten the bandage by squeezing the operating rod 14. At this time, the sleeve 2 can be rotated to drive the fixed rod 21 to rotate, so that the loose part of the bandage is wound around the middle part of the sleeve 2. After the bandage is wound to the middle part of the sleeve 2 and is tightened to a certain extent, the sleeve 2 is loosened. At this time, the sleeve 2 is limited by the second limiting plate 23 and is difficult to rotate. Through the above structure, when the flaw detector body 1 is moved to the middle part of the detected object which is relatively thin, the loose bandage can be quickly adjusted, and the use convenience and applicability of the device are improved.
[0025] As shown in the figure, Figures 1 to 4 The middle part of the sleeve 2 is provided with a plurality of sliding grooves 3, the middle part of the plurality of sliding grooves 3 is slidably connected with a limiting ring 31, the middle part of the limiting ring 31 is provided with a connecting hole 32.

Through the above structure, the fixed rod 21 is changed from one-end support to two-end support, and the deformation of the fixed rod 21 caused by stress is reduced.
[0026] As shown in the figure, Figures 1 to 3 The side wall of the mounting block 16 is fixedly connected with a baffle 4, the middle part of the mounting seat 12 is provided with a slot 41. During work, after the shaft rod 13 is installed in the middle part of the mounting seat 12, the mounting block 16 is slid to make the baffle 4 inserted into the inside of the baffle 4, so that when the shaft rod 13 is forced by the operating rod 14, the shaft rod 13 is difficult to contact with the operating rod 14. Through the above structure, the damage of the screw caused by the extrusion of the middle part of the shaft rod 13 to the operating rod 14 is reduced, and the situation that the operating rod 14 cannot be normally rotated is also reduced.
[0027] As shown in the figure, Figure 4 The middle part of the sleeve 2 is provided with a plurality of insertion holes 5, the plurality of insertion holes 5 are arranged in a circumferential array at the middle part of the sleeve 2. During work, when it is needed to rotate the sleeve 2, a rod-shaped object can be inserted into the inside of the connecting rope 6 to drive the sleeve 2 to rotate. In this way, the torque can be improved, the rotation of the sleeve 2 is more labor-saving, the bandage can be adjusted to a more tightened state, and the fixing effect of the bandage on the flaw detector body 1 is improved. Through the above structure, the bandage can be conveniently adjusted to a more tightened state, and the fixing effect of the bandage on the flaw detector body 1 is improved.
[0028] As shown in Figures 1 to 4 The side wall of the second limiting plate 23 is fixedly connected with a connecting rope 6, and the other end of the connecting rope 6 is fixedly connected to the side wall of the first limiting plate 17. During operation, one end of the connecting rope 6 can be pulled to release the restriction of the first limiting plate 17 on the shaft rod 13 or to release the restriction of the second limiting plate 23 on the sleeve 2, or the middle part of the connecting rope 6 can be directly pulled with great force to drive the first limiting plate 17 and the second limiting plate 23 to move while releasing the restriction on the shaft rod 13 and the sleeve 2. Through the above structure, the rotating restriction state of the shaft rod 13 and the sleeve 2 can be conveniently released, the use convenience of the device is improved, and the situation that the components move quickly after releasing kinetic energy and hit the hands of the operator is reduced.
[0029] As shown in Figure 1 The operation rod 14 is arc-shaped, and the inner side curvature of the operation rod 14 is the same as the middle curvature of the flaw detector body 1. During operation, after the use of the flaw detector body 1 is completed, the shaft rod 13 can be disassembled from the middle of the mounting seat 12, the operation rod 14 is turned over, and then the shaft rod 13 is installed into the mounting seat 12, so that the operation rod 14 is attached to the middle of the flaw detector body 1. Through the above structure, the operation rod 14 can be conveniently stored, the space occupation of the device is reduced, and the use convenience of the device is improved.
[0030] In operation, the flaw detector body 1 is placed in the middle of the pipeline to be detected, and then the band is used to fix the flaw detector body 1. When installing the band, the band is passed through the inside of the operating rod 14, then the shaft 13 is installed in the middle of the mounting seat 12, and the bolt 15 is turned to close the mounting seat 12. At the same time, the first limiting plate 17 will be in contact with the middle of the shaft 13 under the elastic force of the spring 18. After installation is completed, the band is in a slightly relaxed state, so that the position of the flaw detector body 1 can be adjusted conveniently. After adjustment is completed, one end of the operating rod 14 is pulled and the other end of the operating rod 14 is squeezed to the middle of the band through the lever principle with the shaft 13 as the fulcrum, so that the band is tightly tightened. At this time, the shaft 13 is limited by the first limiting plate 17 and is difficult to rotate, so that the flaw detector body 1 is tightly bound to the pipeline. When the position of the flaw detector body 1 needs to be adjusted for the detection of one place of the pipeline, the first limiting plate 17 is pulled to release the rotation limitation of the shaft 13, so that the middle of the band is no longer stressed and becomes relatively loose, so that the position of the flaw detector body 1 can be adjusted conveniently. The band is wound around the middle of the fixed rod 21. When the flaw detector body 1 needs to be moved to the middle of a thinner pipeline, the band will become loose and it is difficult to tighten the band through the squeezing of the operating rod 14. At this time, the sleeve 2 can be rotated to drive the fixed rod 21 to rotate, so that the loose part of the band is wound around the middle of the sleeve 2. After the band is wound to the middle of the sleeve 2 and is tightened to a certain extent, the sleeve 2 is loosened. At this time, the sleeve 2 is limited by the second limiting plate 23 and is difficult to rotate. After the band is wound around the middle of the fixed rod 21, the limiting ring 31 is slid to make the connecting hole 32 fit around the middle of the fixed rod 21, so that after the band is tightened, the deformation of the fixed rod 21 caused by the tension of the band is reduced. After the shaft 13 is installed in the middle of the mounting seat 12, the mounting block 16 is slid to make the baffle 4 inserted into the inside of the baffle 4, so that when the operating rod 14 applies force to the band, the shaft 13 is difficult to contact the operating rod 14. When the sleeve 2 needs to be rotated, a rod-shaped object can be inserted into the inside of the connecting rope 6 to drive the sleeve 2 to rotate. In this way, the torque can be improved and the rotation of the sleeve 2 is more labor-saving. At the same time, the band can be adjusted to a more tightened state. One end of the connecting rope 6 can be pulled to release the limitation of the shaft 13 by the first limiting plate 17 or the limitation of the sleeve 2 by the second limiting plate 23, or the middle of the connecting rope 6 is directly pulled with great force to drive the first limiting plate 17 and the second limiting plate 23 to move and release the limitation of the shaft 13 and the sleeve 2. After the use of the flaw detector body 1 is completed, the shaft 13 can be removed from the middle of the mounting seat 12 and the operating rod 14 is turned over and then the shaft 13 is installed in the inside of the mounting seat 12, so that the operating rod 14 is attached to the middle of the flaw detector body 1, reducing the space occupation of the device.
