The specific scheme is as follows: it includes a pipe 1 and a pipe 2, which are connected by a sleeve 3, and the sleeve 3 can facilitate the connection between the pipe 1 and the pipe 2.

[0021] See also Figure 2 and Figure 4 , wherein the sleeve member 3 comprises a clamping sleeve 1 31 and a clamping sleeve 2 32, wherein the clamping sleeve 1 31 is plugged into the clamping sleeve 2 32, and the clamping sleeve 1 31 and the clamping sleeve 2 32 are respectively sleeved onto the pipe 1 1 and the pipe 2 2, and a transfer block 36 is arranged between the pipe 1 1 and the pipe 2 2, and the transfer block 36 is arranged inside the clamping sleeve 1 31, and the centers of the transfer block 36, the clamping sleeve 1 31, and the clamping sleeve 2 32 are collinear. The end faces of the transfer block 36 are both annularly provided with plug-in rods 38, and the opposite end faces of the pipe 1 and the pipe 2 2 are both provided with plug-in holes 37 for plugging in the plug-in rods 38, and the plug-in rods 38 are cone-shaped, and the number of the plug-in rods 38 and the number of the plug-in holes 37 are equal. After the pipe 1 and the pipe 2 are connected by the sleeve 3, the plug rod 38 is inserted into the corresponding sockets 37 on the pipe 1 and the pipe 2, which can effectively limit the relative rotation of the transfer block 36 and the pipes 1 and 2.

[0022] Furthermore, a second flexible pad 35 and a first flexible pad 33 are respectively provided between the clamping sleeve 1 31 and the clamping sleeve 2 32 and the corresponding pipe 1 1 and pipe 2 2, wherein the second flexible pad 35 and the first flexible pad 33 are both made of flexible rubber material. By providing the second flexible pad 35 between the clamping sleeve 1 31 and the pipe 1 1, and providing the first flexible pad 33 between the clamping sleeve 2 32 and the pipe 2 2, the contact tightness of the clamping sleeve 1 31 and the clamping sleeve 2 32 can be further improved, thereby further ensuring the connection stability of the pipe 1 and the pipe 2 2, and it is worthy of popularization and use.
