Embodiment

Detailed description of relevant the utility model and technology contents, with the conjunction with figs. explanation as follows, yet appended accompanying drawing is not to be used to limit to the utility model only as illustrative purposes.

Please with reference to Fig. 1, be the schematic perspective view of the detector bar of the utility model, the utility model provides a kind of detector bar with rotatable portable probe, and detector bar 1 comprises main sleeve pipe 10 and rotatable portable probe 20.

Please, be respectively the cross-sectional schematic of schematic perspective view, decomposing schematic representation and the detector bar of the rotatable portable probe of the utility model with reference to Fig. 2 to Fig. 4.Rotatable portable probe 20 comprises contact tube 21, shank 22, rotation moving structure 23 and insulating sleeve 24; Contact tube 21 is contained in main sleeve pipe 10 inside, and contact tube 21 comprises copper pipe 211, stopper rod 212 and volute spring 213, is provided with signal transmission module in the stopper rod 212, and stopper rod 212 is provided with reference column 2121; Shank 22 has section of detection 221 and accommodation space 223; Rotation moving structure 23 includes external thread 231 and internal thread 232.

The external thread 231 of rotation moving structure 23 is molded over a side of shank 22, and the side that shank 22 forms external thread 231 is arranged in the copper pipe 211; The internal thread 232 of rotation moving structure 23 takes shape in the internal face of a side of copper pipe 211 contiguous shanks 22, is spirally connected each other through external thread 231 and internal thread 232, makes shank 22 do linear moving with respect to copper pipe 211; In addition, the outside dimension of shank 22 is less than the internal diameter size of copper pipe 211.
