[0014] Compared with the prior art, the present application has the following advantages:

After adjustment, tightening the nut fixes the tilt angle of the probe. This adjustment method is simple to operate, can quickly adapt to the tilt requirements of different detection surfaces, and improves detection efficiency.

[0017] 3. In this invention, pulling the connecting rod causes the spring to contract, separating the fixed block from the gear. At this point, the rotating disk can be freely rotated to adjust the rotation angle of the probe. After adjustment, releasing the connecting rod causes the spring to reset, allowing the fixed block to re-engage with the gear, thus locking the angle. This design not only provides comprehensive rotation adjustment capabilities but also ensures the accuracy and stability of angle adjustment, adapting to the multi-angle detection needs of complex curved surfaces.

[0030] In this embodiment, a rotation angle adjustment unit 3 is provided on the lower side of the tilt angle adjustment unit 2. The rotation angle adjustment unit 3 includes a fixed base 31, a rotating shaft 32 is connected to the inner side of the fixed base 31, a rotating disk 33 is connected to the upper end of the rotating shaft 32, a gear 34 is connected to the rotating shaft 32, the rotation angle adjustment unit 3 also includes a fixed block 35, a connecting rod 36 is connected to one side of the fixed block 35, a spring 37 is provided on the outer side of the connecting rod 36, and a connecting frame 38 is connected to the inner side of the fixed base 31.

[0031] Specifically, the threaded sleeve 15 is threaded to the outside of the telescopic adjustment threaded rod 14, the probe body 16 is fixedly disposed at one end of the threaded sleeve 15, and the threaded sleeve 15 and the probe body 16 are slidably connected to the inside of the fixed cylinder 11.

[0032] In this embodiment, the connecting piece 17 is provided in two sets and symmetrically arranged on both sides of the probe body 16. One end of the limiting slide rod 18 is threaded to the connecting piece 17. The limiting slide rod 18 is slidably connected to the connecting piece 17 and slidably connected to the hole provided on the fixing cylinder 11.

[0033] Specifically, the drive motor 13 is fixedly installed at the middle position inside the fixed ring 12, the retaining ring 24 is provided in two sets and symmetrically arranged on both sides of the fixed cylinder 11, and the fixed threaded rod 23 is fixedly installed on the retaining ring 24.

[0034] In this embodiment, the nut 22 is fixedly mounted on the rotating disk 33, the fixed threaded rod 23 is slidably connected to the elastic fixing plate 21, one side of the elastic fixing plate 21 is attached to one side of the retaining ring 24, the nut 22 is threadedly connected to the fixed threaded rod 23, and one side of the nut 22 is attached to one side of the nut 22.

[0035] Specifically, the rotating shaft 32 is rotatably connected to the inner middle position of the fixed base 31, the rotating disk 33 is rotatably connected to the inner side of the fixed base 31, and the gear 34 is fixedly connected to the outer side of the rotating shaft 32.

[0036] In this embodiment, the connecting frame 38 is fixedly disposed on the inner side of the fixing base 31, the connecting rod 36 is slidably connected to the fixing base 31, and the two ends of the spring 37 are respectively fixedly connected to one side of the fixing block 35 and the inner side of the fixing base 31.

[0037] Specifically, the fixing block 35 is slidably attached to the inner side of the gear 34, the fixing block 35 is slidably connected to the inner side of the connecting frame 38, and the gear 34 is disposed on the lower side of the rotating disk 33.

[0038] Working principle or structural principle: First, by sliding the probe body 16 and the connecting piece 17 into the inner side of the fixed cylinder 11, and simultaneously rotating the connecting piece 17 and the probe body 16, the threaded sleeve 15 is threadedly connected to the telescopic adjusting threaded rod 14. When the threaded sleeve 15 is fully threadedly connected to the telescopic adjusting threaded rod 14, the connecting piece 17 corresponds to the hole on the fixed cylinder 11. At this time, the limiting slide rod 18 passes through the sliding connecting piece 17 and slides into the hole on the fixed cylinder 11. At the same time, one end of the limiting slide rod 18 is threadedly connected to the connecting piece 17. By starting the drive motor 13, the telescopic adjusting threaded rod 14 is driven to rotate, and the threaded sleeve 15 is driven to move. At the same time, the connecting piece 17 drives the limiting slide rod 18 to slide on the fixed cylinder 11, which can drive the probe body 16 to extend.

[0039] By rotating the nut 22, the nut 22 is separated from the elastic fixing plate 21, which loosens the elastic fixing plate 21 and the retaining ring 24. This allows for adjustment of the tilt angle between the probe body 16 and the fixing cylinder 11. By rotating the nut 22 in the opposite direction, the elastic fixing plate 21 is brought into close contact with one side of the retaining ring 24, thus securing the fixing cylinder 11.

[0040] By pulling the connecting rod 36, the spring 37 is retracted, and the fixing block 35 separates from the gear 34. At the same time, the fixing block 35 slides inside the connecting frame 38, allowing the rotating disk 33 to be rotated, which in turn adjusts the rotation angle of the probe body 16. By loosening the connecting rod 36, the spring force of the spring 37 causes the fixing block 35 to re-engage onto the gear 34 to fix the gear 34, thus fixing the rotation angle of the probe body 16.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
