The second connecting block 3 is provided with a first screw hole 3-1 and a second screw hole 3-2 communicating with the outside and the annular groove 31. The first screw hole 3-1 and the second screw hole 3-2 are symmetrically arranged and the extension direction of the first screw hole 3-1 and the second screw hole 3-2 is consistent with the extension direction of the first slot 32 or the second slot 33. The first insert block 21 is provided with a first corresponding screw hole 211 that can form a limiting engagement with the first limiting block 311 and the first screw hole 3-1. The block 22 is provided with a second threaded hole 221 that can form a corresponding second threaded hole 3-2 after forming a limiting engagement with the second limiting block 312. The fixing member is a first screw that can form a threaded engagement with the first threaded hole 3-1 and the first threaded hole 211, and a second screw that can form a threaded engagement with the second threaded hole 3-2 and the second threaded hole 221.

[0030] The working principle of this utility model is as follows: The first insert 21 and the second insert 22 on the first connecting block 2 slide through the first slot 32 and the second slot 33 of the second connecting block 3. After the first insert 21 and the second insert 22 enter the annular groove 31, the first connecting block 2 is rotated, so that the first insert 21 and the second insert 22 slide in the annular groove 31 until the first insert 21 and the second insert 22 contact the first spring 4 and the second spring 5 and are continuously compressed. The first threaded hole 211 and the second threaded hole 221 on the first insert 21 and the second insert 22 correspond to the first threaded hole 3-1 and the second threaded hole 3-2 on the second connecting block 3. Then, by rotating the first screw drive handle 6, the first screw is driven to form a threaded engagement with the first screw hole 3-1 and the first threaded hole 211. By rotating the second screw drive handle 6, the second screw is driven to form a threaded engagement with the second screw hole 3-2 and the second threaded hole 221, so that the first insert block 21 and the second insert block 22 are fixed in the annular groove 31. At this time, the first connecting block 2 and the second connecting block 3 form a detachable fixation, and the compensation tube body 1 is fixed to the straight connecting tube. Then, by the elastic force of the first spring 4 and the second spring 5, the first screw is difficult to disengage from the threaded engagement with the second screw hole 3-2 and the second threaded hole 221, thus strengthening the fixation between the compensation tube body 1 and the straight connecting tube.
