1. Field of the Invention
The present invention generally relates to a tubular connection structure, more particularly, to a tubular connection structure that is to closely fasten tubes and a tubular connection body and prevent a clasp lever of the tubular connection structure to be easily loosened up.
2. Description of the Prior Art
For a prior tubular connector, which has a joining axle hole, at least one side of the tubular connector is selected to have at least one open and at least one pivotal portion so as to make a pivotal connection for a fastening handle . By swinging the fastening handle, a convex portion of the front end of the fastening handle may urge onto a male connector or a ring-type concave wall in order to have the functions of connecting tubes or close. As it can be seen, the convex portion of the front end of the fastening handle is the only way to have the function of stop and short of a security device for preventing that the tubular connector is loosened up. So the conditions of vibrations, external forces, other man-made factors, etc. may loosen up or take off the two connected tubular connectors, the liquid inside the connectors may overflow to contaminate environment and damage human beings.
Hence, how to develop a product for figuring out the disadvantages of the prior art may be an important issue to the people skilled in the art.
