[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] refer to Figures 1 to 3 A quick-release double-section rod connection structure of this embodiment includes a first support rod 1 and a second support rod 2. The first end of the first support rod is detachably connected to the first end of the connecting sleeve. The connection method between the first support rod and the connecting sleeve adopts the existing technology, which will not be repeated here. A fastening and limiting assembly is provided on the second end of the connecting sleeve. Correspondingly, an anti-bonding connector is provided on the end of the second support rod that is connected to the second end of the connecting sleeve. The anti-bonding connector is detachably connected to the fastening and limiting assembly.

[0020] Among them, the anti-adhesion connector includes an injection-molded sleeve body 3. In the present application, the sleeve body is made of plastic material, which can effectively prevent it from bonding with the inner wall of the first support rod. A shrinking plug-in section 4 is formed on the sleeve body, and a snap-on buckle 5 is integrally formed on the plug-in section. Correspondingly, a snap-on hole 6 is opened on the end of the second support rod, and the plug-in section is plugged and connected to the end of the second support rod, and the snap-on buckle is buckled in the snap-on hole; a convex limiting block 7 is also provided on the plug-in section, and an embedding groove 8 is formed on the port of the second support rod. When the plug-in section is plugged into the end of the second support rod, the limiting block is embedded in the embedding groove The limit block protrudes from the surface of the second support rod, and correspondingly, the fastening limit assembly includes a travel groove 9 opened on the side wall of the connecting sleeve, and the bottom end of the travel groove is connected to a limit groove 10, and fastening seats 11 are arranged on both sides of the top opening of the travel groove, and a fastening nut (not shown) is connected to the fastening seat. During installation, the limit block is inserted into the limit groove along the travel groove, and the first support rod is clamped by the fastening nut, wherein the inner diameter of the travel groove is larger than the inner diameter of the limit groove, so that the limit block is inserted more smoothly, and circumferential locking can be achieved through the limit groove, and during insertion, the outer wall of the second support rod is non-contact with the inner wall of the connecting sleeve.
