The upper end of the sliding rod 1 is slidingly connected with the slide rail frame 2. Correspondingly, a sliding groove is provided on the slide rail frame 2, and a wire outlet hole is provided on the upper end of the slide rail frame 2, which is in communication with the sliding rod 1. A sliding through groove is provided on the sliding rod 1, the rotating connecting seat 13 is fixed to the inner side end of the sleeve rod 4, the threaded end 14 is provided at the end of the rotating rod 15 and is screwed with the rotating connecting seat 13, the abutting piece 9 is fixed to the rotating rod 15, and the sliding rod 1 and the sleeve rod 4 are slidingly connected.

[0033] As shown in Figure 1 and Figure 4 , the pipeline can pass through the cavity formed by the sleeve of the sliding rod 1 and the sleeve rod 4, and then pass out of the wire seat 8. When the experimenter needs to move the position of the wire, the sliding rod 1 can be pushed to slide along the sliding groove on the slide rail frame 2, so that the length of the sliding rod 1 and the sleeve rod 4 after being sleeved is changed to adapt to the length of the pipeline, avoiding the pipeline from being pulled off.

[0034] When the length of the sliding rod 1 and the sleeve rod 4 is adjusted, the side end of the sliding rod 1 and the sleeve rod 4 can be abutted by rotating the threaded end 14 on the rotating rod 15 into the rotating connecting seat 13 (the rotating connecting seat 13 and the inner side end of the sleeve rod 4 are fixed). After abutting, the sliding rod 1 and the sleeve rod 4 are abutted to each other and cannot move relative to each other.

[0035] As shown in Figure 6 , the experimenter can push the sliding rod 1 and the sleeve rod 4 to the right and the left according to the actual situation, so that the pipeline is not directly aligned with the gas phase heat dissipation panel, and the pipeline is arranged around the edge.

[0036] As shown in Figure 3 , the side end of the sleeve rod 4 is provided with a notch through which the abutting piece 9 passes. The notch is designed mainly for the insertion of the abutting piece 9, so as to abut with the sliding rod 1.

[0037] In this embodiment, the upper end of the sliding rod 1 is provided with a limiting sliding head 12, and the limiting sliding head 12 is located in the inside of the sliding rail frame 2.

[0038] In this embodiment, the outlet hole is fixedly connected with a rotating ring 11, and the rotating ring 11 is rotatably connected with a wire seat 8. The rotating ring 11 and the wire seat 8 are rotatably connected, and the experimenter can rotate the wire seat 8, so as to adjust the direction of the pipeline joint.

[0040] In this embodiment, the wire seat 8 is provided with a dismounting notch 6, and the fixed plate 7 is provided with a push piece 5 which is correspondingly located in the dismounting notch 6. The fixed plate 7 functions to limit the pipeline.

[0041] In this embodiment, the sliding rail frame 2 is provided with wire conduits at both side ends. The wire conduits at both sides can be connected with different pipelines respectively, and correspondingly connected with different detectors.
