[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When in use, four first connecting strips are used to fix the four connecting plates together, and one of the pipe sections is inserted into the circular slot. At this time, the first heat shrink tape is pasted on the inner wall of the circular slot, so the first heat shrink tape can be sleeved on the outside of the pipe. By tightening each connecting bolt, the connecting bolt can be tightly against the pipe to complete the installation of the connecting plate. By using four second connecting strips to fix the four fixing blocks together, the inner walls of the four fixing blocks form a circle, which can cover another section of the pipe. By fixing the mounting plate and the fixing block, the inside of the four mounting plates forms a circle that wraps the pipe. By pasting the second heat shrink tape on the inner walls of the four fixing blocks, after determining the position of the fixing blocks and the pipe, tighten each tightening strip. The fixing bolts are arranged so that the fixing bolts are tightly against the surface of the pipe. When the four fixing bolts are tightly against the pipe, the fixing block is tightly installed on the outside of the pipe. At this time, the connecting piece formed by the four connecting plates and the connecting piece formed by the four fixing blocks are connected. The connecting plates and the fixing blocks are connecting pieces made of stainless steel metal, which have the advantages of corrosion resistance and high strength. The sealing block is inserted into the sealing groove. The sealing block is made of hard rubber, and the inner wall of the sealing groove is coated with a rubber coating. When the sealing block is stuck in the sealing groove, it has good sealing performance and the liquid inside the pipe will not leak. At the same time, the connecting pipe will be inserted into the pipe wrapped by the fixing block. The sealing ring is made of rubber and has good sealing performance. The connecting pipe is inserted into the pipe to have a sealing and leak-proof effect.

[0019] 2. When in use, the first heat shrinkable tape and the second heat shrinkable tape are made of polyolefin materials, which have high strength and corrosion resistance. After the connecting plate and the fixing block are wrapped around the pipe, hot air is blown to the first heat shrinkable tape and the second heat shrinkable tape by using a hot air blower. Under the action of the hot air, the first heat shrinkable tape and the second heat shrinkable tape will shrink and can fit tightly on the surface of the pipe, thereby forming a good anti-corrosion and sealing layer, which can effectively prevent water and moisture from entering the pipe interface, and can also prevent the leakage of the medium inside the pipe, ensuring the sealing and safety of the pipe. The first heat shrinkable tape and the second heat shrinkable tape have good insulation properties, which can effectively prevent the current conduction between the pipe and the surrounding environment, and avoid electrochemical corrosion of the pipe or safety accidents caused by leakage.

[0020] 3. When in use, by putting the connecting frame on the outside of the four fixed blocks, the positioning lock is inserted between the same set of symmetrical movable plates. The teeth on both sides of the positioning lock are constantly engaged with the positioning groove when sliding. Under the elastic force of the torsion spring, the two movable plates will continuously expand and contract to both sides. At this time, the positioning buckle is active inside the movable hole. When it is constantly engaged, the more the positioning lock is inserted into the positioning groove, the tighter it is fixed. When installing, only sliding cooperation is required. The installation method is simple and fast, and the installation can be completed without professional technology. When disassembly is required, by pulling the traction ring outward, the traction ring can simultaneously drive the four fixed pull rods to move under the connection of the reinforcement nail. At this time, the slider slides inside the slide groove. When the traction ring is pulled, the four fixed pull rods will simultaneously move multiple movable plates in the direction close to the mounting plate. Since the movable hole is inclined, the movable plate will expand outward at the same time when being pulled, so the engagement between the positioning groove and the positioning lock will be released, thereby achieving the benefit of quickly dismantling the two connected pipes.
