As shown in fig. 1, the CVC tube fixing device of this embodiment includes a fixing base 1, a main tube 2 is connected to one end of the fixing base 1, at least one extension tube 3 (generally, one, two or three) is connected to the other end of the fixing base 1, and two fixing holes 4 are respectively disposed on two sides of the fixing base 1.

As shown in fig. 2 to 5, the CVC tube fixing device of the present embodiment includes an application 5, a connecting plate 6 is provided in the middle of the upper surface of the application, a positioning column 7 matched with the fixing hole 4 is provided on the connecting plate 6, and an expansion part 8 is provided at the end of the positioning column 7; two reference column 7 penetrate two fixed orificess 4 respectively and are used for fixed fixing base 1, and inflation portion 8 is used for preventing reference column 7 from droing in the fixed orifices 4.

The expansion part 8 is made of rubber, which is a material with good flexibility, is rich in elasticity, can generate large deformation under the action of small external force, and can recover the original shape after the external force is removed. The size of the expanded portion 8 should be larger than the size of the fixing hole 4, and the expanded portion 8 can be pressed into the fixing hole 4 by applying a small external force.

The inner diameter of the fixing hole 4 should be slightly larger than the diameter of the positioning post 7, for example, larger than 0.5-1.5 mm.

In order to better prevent the positioning column 7 from falling off from the fixing hole 4, the expansion part 8 is in a circular truncated cone shape, the larger circular end face of the expansion part faces the connecting plate 6, namely after the expansion part 8 is pressed into the fixing hole 4, the larger circular end face of the expansion part can abut against the fixing seat 1, and the expansion part 8 cannot easily exit from the fixing hole 4. The fixing seat 1 can be taken down only when external force is applied.

In order to improve the comfort of use and avoid discomfort caused by pressing the expansion part 8 into the fixing hole 4, the area of the connecting plate 6 should be set to be large, and the connecting plate 6 can be stuck on the application 5.

One side of the connecting plate 6 is provided with a first fixing part for fixing the main tube 2, the first fixing part comprises a flexible sheet 9 arranged on the applicator 5, and the flexible sheet 9 is provided with a bending groove (not shown in the figure) matched with the main tube 2.

The flexible sheet 9 may be made of rubber so that the main body tube 2 can be pressed into a curved groove which forms a curve conforming to the shape of the curved groove, and the curved groove may take the form of an S-shaped groove or an L-shaped groove. As shown in FIG. 3, the central angle of the arc of the cross section of the curved groove is greater than 180 degrees, preferably 250 degrees and 270 degrees, so that the curved groove can wrap most of the main body tube 2 to prevent the main body tube 2 from easily falling off from the curved groove.

When the CVC tube at the outer section of the body bears heavy traction, the main tube 2 can be pulled out only by changing different directions once (when an L-shaped groove is selected), twice (when an S-shaped groove is selected) or multiple times, so that the CVC tube has good anti-tube-falling capacity.
