The inner surface of the capsule-shaped fastener 331 is in movable contact with the outer surface of the wire 21. A protective sleeve 332 is fixedly connected to one end of the capsule-shaped fastener 331 near the braided bent probe 32. The outer surface of the capsule-shaped fastener 331 is threadedly connected to the inner wall of the center of the probe mounting base 34. The probe body 341 is rotatably connected to the inner side of the probe mounting base 34. A fine-tuning component is provided between the probe body 341 and the probe mounting base 34. In this embodiment, the structure of the ultrasonic testing probe is optimized, replacing the traditional integrated design. When assembling the braided curved probe 32 with the wiring module 2, the mating port of the braided curved probe 32 abuts against the mating port of the wiring module 2. The hand-held screw-on sleeve 312 is screwed inward from the end of the threaded sleeve 311 fitted on the outer end of the wiring module 2 away from the braided curved probe 32. The other end of the threaded sleeve 311 is connected to the interface deformation ring 313 and the fastening nut 314 for a matching screw connection. When the fastening nut 314 is tightened, the assembly between the wiring module 2 and the braided curved probe 32 is achieved, while also facilitating disassembly and assembly. When adjusting the direction of the probe body 341, the corresponding traction steel wire 23 is pulled, causing the probe body 341 to turn along the pulled side. Through the cooperation of the support collar 322 and the curved rib 3221, the traction steel wire 23 is limited and connected while absorbing deformation pressure, as shown in the attached figure. Figure 6 As shown, when the probe body 341 is being adjusted for direction, the braided curved probe tube 32 bends.

Specifically, the swing contact plate 3232 and the elastic connecting piece 3233 abut against the side wall of the braided curved probe tube 32, and the braided curved probe tube 32 is connected to the connecting cover 33 through the connecting ring 321, which prevents the braided curved probe tube 32 from being directly twisted when turning, and can also protect the wire 21, further improving the service life of the wire 21 and the braided curved probe tube 32.

[0020] Example 2, see attached document Figures 1-15 Based on Embodiment 1, in order to enhance the sealing effect at the connection between the wiring module 2 and the braided curved probe 32: a tapered tail sleeve 3121 is embedded and installed at the end of the screw-on sleeve 312 away from the braided curved probe 32, and a sealing ring 3122 is fixedly installed on the inner ring surface of the tapered tail sleeve 3121.

A reserved groove 3130 is correspondingly opened on the outer ring surface of the interface deformation ring 313 and the insulating pad 3131. In this embodiment, a tapered tail sleeve 3121 is installed at one end of the screw-in sleeve 312. Through the narrowing structural design, the tapered tail sleeve 3121 and the sealing ring 3122 are tightly attached to the outer wall of the wiring module 2. The sealing ring 3122 and the sealing ring 31311 here not only ensure the sealing of the installation, but also adapt to deformation, so that the gap at the interface is compensated.

[0021] Example 3, refer to Appendix Figures 1-15 Based on Embodiment 2, in order to achieve smooth traction of the traction steel wire 23: the cross-section of the support collar 322 is in the shape of an "I"; multiple sets of curved ribs 3221 are arranged in a circular array about the central axis of the protective sleeve 332; a J-shaped limiting spring block 3230 is fixedly added to the outer surface of the embedded ring plate 323, the inner wall of the J-shaped limiting spring block 3230 is connected to the traction steel wire 23 through and is movably connected to the outer surface; a receiving groove is opened on the curved clamping plate 3231, and a guide wheel 32311 is rotatably installed inside the receiving groove, the outer surface of the guide wheel 32311 is in movable contact with the outer surface of the traction steel wire 23; the inner surface of the curved clamping plate 3231 is in movable contact with the outer surface of the J-shaped limiting spring block 3230; In this embodiment, the J-shaped limiting spring block 3230 is used to limit the four sets of traction steel wires 23, avoiding wear caused by directly passing through the embedded ring plate 323. When the probe body 341 is rotated and adjusted, the braided curved probe tube 32 bends. Here, the J-shaped limiting spring block 3230 abuts against the curved clamping plate 3231 on the inwardly bent side, which plays an auxiliary support role for the curved clamping plate 3231. Furthermore, by setting the guide wheel 32311 on the curved clamping plate 3231, the direct contact is changed to rolling contact, reducing the wear on the traction steel wires 23 and further extending the overall service life of the equipment.

[0022] Example 4, see attached document Figures 1-15 Based on Embodiment 3, the cable sheath 332 is composed of a conical sleeve 1 3321 and a conical sleeve 2 3322 and is integrally formed.
