[0017] Compared with the prior art, the advantages of the present invention are:

[0018] The utility model, through the control component set up, when it is necessary to clean the joint of the digital remote pressure gauge, first apply an upward force to the limit rod, and after the limit rod is pulled out from the inside of the movable rod, apply a pushing force to the movable rod, and after the movable rod is pushed to one side of the movable groove, the joint is placed on the outer surface of the silicone block, and after the movable rod is pushed to the bottom of the support plate, the force applied to the limit rod is cancelled.

Under the setting of the inclined plate 9, the dust in the collection frame 91 is prevented from floating inside the fixed frame 8, which increases the workload of cleaning the joint. After cleaning the joint, under the action of the connecting shaft 94, an upward flipping force is applied to the rotating column 95. After the rotating column 95 is lifted out of the second connecting frame 93, the first connecting frame 92 is adjusted to a vertical state. Then, holding the first connecting frame 92 and the outer surface of the rotating column 95, a pulling force is applied to the collection frame 91 to remove the collection frame 91 from the inside of the fixed frame 8, and the excreted impurities can be centrally processed.
