[0024] Referring to Fig. 3 The appearance of fixed ring 4 and air bag 8 is both set as C shape, and fixed ring 4 has certain elasticity and can be bent until two end surfaces contact.
[0025] When rotating bidirectional screw rod 11, two fixed blocks 5 are close to the middle, arc block 6 is pushed into the inside of fixed ring 4, rubber block 7 is pushed by arc block 6, the inside of fixed ring 4 and air bag 8 is all filled with water, arc block 6 and rubber block 7 enter the inside of fixed ring 4, occupy space and push the water in fixed ring 4 to the inside of fixed ring 4 through through pipe 9, the volume of air bag 8 will expand and thus more closely fit the outer wall of first connecting pipe 2 and second connecting pipe 3.
[0026] Referring to Figs. 1-3 Two symmetrical fixed blocks 5 are fixedly installed on the arc outer wall of fixed ring 4, and bidirectional screw rod 11 is arranged between two fixed blocks 5.
[0027] The user can rotate the two-way threaded rod 11 by turning the handle, and the fixed blocks 5 are connected to the two-way threaded rod 11 by threads. The two fixed blocks 5 move towards each other at this time, and the two fixed blocks 5 are installed on the outer wall of the fixed ring sleeve 4 near the two end faces. The two fixed blocks 5 will bring the two end faces of the two fixed ring sleeves 4 closer to each other, thereby fixing the air energy water heater heat exchanger 1 and the second connecting pipe 3.
[0028] Referring to Fig. 3 , one end of the arc block 6 is fixedly installed on one end face of the fixed ring sleeve 4, and the other end extends into the interior of the fixed ring sleeve 4. The outer wall of the rubber block 7 is in contact with the inner wall of the fixed ring sleeve 4.
[0029] The arc block 6 has a certain elasticity in shape and is relatively hard in texture. When the rubber block 7 advances in the fixed ring sleeve 4, the rubber block 7 has a sealing property in contact with the inner wall of the fixed ring sleeve 4 due to the characteristics of the rubber block 7. The rubber block 7 can squeeze the water in the fixed ring sleeve 4, but the water will not leak from the edge between the rubber block 7 and the fixed ring sleeve 4.

[0034] Referring to Fig. 3 , the threads on both sides of the circular sheet 10 on the two-way threaded rod 11 are opposite in direction.
[0035] By rotating the two-way threaded rod 11, the distance between the two connection components can be expanded or reduced to adapt to the connection requirements of different sizes.
