Embodiment Construction
[0013] A cylinder 2 made of transparent hard material (hard transparent material is glass, hard plastic, etc., which can withstand pressure, and the deformation caused by pressure is relatively small and negligible) has external threads at both ends, which can pass The external thread of the cylinder 2 and the internal thread of the sealing cap 1 realize the sealing of the air inside the cylinder (using a gasket) at both ends of the cylinder 2. This sealing is a prior art and can be a common nut (equivalent The sealing cap of the device), threads, gaskets, or other sealing methods; there are two cylinder center rings 6 at the center of the outside of the cylinder 2, and the center of the two cylinder center circles 6 is the symmetrical center of the cylinder 2 , in other words, the distance from the center of symmetry to the ends of the cylinder 2 is equal, there is a horizontal bubble 7 on the outer surface of the cylinder 2, and the cylinder 2 is fixed on a bracket (for the c...
