[0029] Working principle: When storing the detection rod 5, by pulling the detection rod 5, it can be smoothly slid inside the hollow tube 4. The spring 7 on the fixing block 6 will be gradually compressed. After the detection rod 5 is completely stored inside the hollow tube 4, the first connecting rod 8 and the second connecting rod 9 are precisely engaged together. This is to ensure that the detection rod 5 can be better protected during subsequent handling, carrying or storage, thus achieving quick and safe storage of the detection rod 5 and improving the convenience of carrying it. During the tightening and loosening of the wire 205, the turntable 202 is rotated, and the rotation of the turntable 202 will drive the rotating shaft 201 fixed to it to rotate accordingly. As the rotating shaft 201 rotates, the wire 205 will gradually wrap around the rotating shaft 201. When the wire 205 is completely wrapped, the cooperation between the fixing rod 204 and the connecting groove 203 can ensure that the wire 205 is firmly fixed in the appropriate position. Then, the other end of the wire 205 is inserted into the buckle 206, thus realizing the winding and tightening operation of the wire 205.
