[0047] The two limiting pieces 36 are rotated to be separated from the interiors of the two first grooves 37, and then the top block 34 can be pulled out from the placing groove 33 through the hand pulling piece 35, and the whole dismounting process is simple, fast, time-saving and labor-saving. When the top block 34 is dismounted, the blocking block 41 no longer blocks the three-prism 42, the two driving handles 30 are driven respectively to rotate the two connecting rods 24 until the limiting block 25 is separated from the interior of the corresponding limiting groove 19, then the hand is loosened, the first spring 26 is not affected by any external force at this time, and it will rebound, the connecting block 20 will return to the original position, and the stop plate 9 returns to the initial position, and thus the dismounting operation of the quick adjusting mechanism is completed, and the whole process does not need to rely on other tools, which is time-saving, labor-saving and high in efficiency.

[0048] In actual use, the two second round rods 12 in the same quick adjusting mechanism are respectively clamped into the interiors of the two through grooves in the same group, and then are turned up along the hinge piece 7 until the bottom end of the main block 8 contacts the flange plate 3. Two fingers are respectively inserted into the interiors of the two finger sleeves 31, and then the wave tube main body 1 is pulled to the middle part direction, the connecting plate 29 drives the two connecting rods 24 to displace together, and the two connecting blocks 20 drive the stop plate 9 to displace synchronously. Through the limiting grooves 19, the quick adjusting mechanism can be adapted to multiple types of pipelines to improve the practicability. According to the width of the flange plate on the pipeline, the two driving handles 30 are driven to rotate the two connecting rods 24 until the limiting block 25 is clamped into the interior of the corresponding limiting groove 19. At this time, even if the hand is loosened, the connecting block 20 will not return to the original position, and at the same time, the three-prism 42 fixed on the top of the connecting block 20 will also displace synchronously. The three-prism 42 will constantly touch the blocking blocks 41 and make them turn over during the displacement process. The process of the three-prism 42 pushing the blocking blocks 41 is irreversible before the top block 34 is removed, that is, the three-prism 42 cannot displace reversely. Thus, the installation of the quick adjusting mechanism is completed. The two limiting pieces 36 are rotated to be separated from the interiors of the two first grooves 37, and then the top block 34 can be pulled out from the placing groove 33 through the hand pulling piece 35, and the blocking block 41 no longer blocks the three-prism 42. The two driving handles 30 are driven respectively to rotate the two connecting rods 24 until the limiting block 25 is separated from the interior of the corresponding limiting groove 19. Then the hand is loosened, the first spring 26 is not affected by any external force at this time, and it will rebound, the connecting block 20 will return to the original position, and the stop plate 9 returns to the initial position, and thus the dismounting operation of the quick adjusting mechanism is completed, and the whole process does not need to rely on other tools, which is time-saving, labor-saving and high in efficiency.
