[0041] In the actual detection process, when it is necessary to adjust the extension length of the power cord 2, the connection part 1 51 and the connection part 2 52 are moved in a direction close to each other, driving the driving plate 61 to be inserted between the storage tray 3 and the damping part 41, so that the damping part 41 is separated from the storage tray 3, making it easy to adjust the length of the power cord 2. When the detection device is installed on the support frame, the connection part 1 51 and the connection part 2 52 are moved in a direction away from each other, so that the support frame is inserted into the positioning port 53. In this process, the damping part 41 is attached to the storage tray 3, reducing the situation where the power cord 2 is accidentally pulled out during the detection process, so that the detection makes the power cord 2 less likely to be too messy.

[0042] The implementation principle of the pile foundation nondestructive testing device of the present application is as follows: during the working process of the testing device, according to the distribution of power supply at the construction site, a corresponding length of power cord 2 is pulled out from the storage tray 3, so that the power cord 2 scattered at the construction site is not too long, which is conducive to reducing the possibility of workers being hit by the power cord 2. When the test is completed, the handle 31 is turned to retract the power cord 2 into the storage tray 3.
