[0038] The supporting device is a plurality of groups of cross supports, and the plurality of groups of cross supports are fixed on the side wall of the extension rod 2.

[0039] The integrated probe device comprises a rotating structure 4 and an eddy current probe device 5. A plurality of sets of cross supports are connected with a connecting rod 6 at one end away from the sleeve 3. The connecting rod 6 is connected with the rotating structure 4 at an end away from the plurality of sets of cross supports.

The high-definition camera at the end of the eddy current probe device 5 can record the details inside the to-be-detected object.

[0040] In the embodiment, the integrated probe device and the supporting device are connected and fixed through the connecting rod 6. The connecting rod 6 is movably connected with the supporting device, so that the integrated probe device part of the device can be disassembled and installed. The adjusting nut 1 is spaced apart from the sleeve 3 by a certain distance. The distance is related to the elastic allowance of the cross support. The sleeve 3 is connected with the extension rod 2 through threads. The adjusting nut 1 is rotated to drive the extension rod 2 to rotate. The plurality of sets of cross supports are pressed inward. The cross supports are gradually opened from being closed, so that the device can be kept in the middle and righted in real time inside the to-be-detected object, and the stability of the travel and measurement data is ensured. The images of the to-be-detected object inside detected in real time by the high-definition camera are displayed through the display device connected with the device.

[0041] The cross support is composed of a support rod A 7 and a support rod B 8. The support rod A 7 and the support rod B 8 are movably connected at the middle points to form an X-shaped support rod.

[0042] One end of the support rod A 7 is connected with the side wall of the extension rod 2. One end of the support rod B 8 is connected with a clamping pipe 9. The support rod B 8 is movably connected with the clamping pipe 9.

That is, in its initial state, this integrated probe mechanism approximates a cylinder, making it easy for the operator to place the device into the object to be tested (e.g., a gas cylinder) with a small opening, a long body, and a large diameter of the straight pipe section. After the device is placed inside the object, rotating the adjusting nut 1 clockwise or counterclockwise opens the cross support, changing it from a closed state to an X-shape, achieving centered support and keeping the device in a central position inside the object, improving the accuracy of inner wall detection. The device moves inside the object via rollers at the end of the cross support, avoiding scratches inside the object.

[0048] One end of the outer wall of the connecting rod 6 is marked with a mark point A10, and one end of the outer thread of the clamping tube 9 is marked with a mark point B11.

[0049] In this embodiment, when the integrated probe device and the support device are connected and fixed by the connecting rod 6, the cutting point of the connecting rod 6 and the clamping tube 9 can be quickly found by aligning the mark point A10 on the outer wall of the connecting rod 6 with the mark point B11 on the outer wall of the clamping tube 9, and the integrated probe device and the support device can be fixedly connected by threads.

[0050] When using the device according to the above embodiments of this utility model, connect the display device, connect the power supply, and start the camera; slowly insert the eddy current probe of the device into the object to be tested. When the device has entered a certain depth, rotate the adjusting nut to rotate the extension rod. Several sets of cross supports are squeezed inward, changing the cross supports from a closed state to an X-shape. This allows the device to remain centered and upright inside the object to be tested in real time. At this time, the device maintains a central position inside the object to be tested and performs internal testing. The internal image of the object to be tested is displayed in real time through the display device. After the test is completed, rotate the adjusting nut to close the cross supports and then remove the device from inside the object.
