[0024] First, the device is connected to an external controller and an external circuit. When the heat exchanger body 4 needs to be installed, the opening of the buckle head 9 is aligned with the L-shaped block 8, and the horizontal handle 24 is turned. The horizontal handle 24 drives the horizontal bidirectional threaded rod 6 to rotate. Under the threaded connection between the horizontal bidirectional threaded rod 6 and the horizontal bidirectional threaded block 7, and under the sliding cooperation between the horizontal bidirectional threaded block 7 and the moving plate 10, the horizontal bidirectional threaded rod 6 drives the two groups of horizontal bidirectional threaded blocks 7 to move in opposite directions, and the horizontal bidirectional threaded block 7 drives the L-shaped block 8 to move in opposite directions, so that the L-shaped block 8 is moved to the inside of the buckle head 9, and the L-shaped block 8 is stuck in the inside of the buckle head 9 to complete the installation of the heat exchanger body 4. The block 8 is a lateral force.

[0030] When the installation spacing of the buckle heads 9 is different, in order to adapt to their different spacings, the vertical handle 23 is rotated, and the vertical handle 23 drives the vertical bidirectional threaded rod 16 to rotate. Under the threaded connection between the vertical bidirectional threaded rod 16 and the vertical bidirectional threaded block 17, and under the sliding cooperation between the vertical bidirectional threaded block 17 and the rotating plate 2, the vertical bidirectional threaded rod 16 drives the two groups of vertical bidirectional threaded blocks 17 to move toward each other, and the vertical bidirectional threaded block 17 drives the two groups of movable plates 10 to move toward each other, and the movable plate 10 drives the L-shaped block 8 to move toward each other, so that the L-shaped block 8 moves to the corresponding position, and then repeats the above operation to complete the clamping and fixing of the heat exchanger body 4. When it is necessary to adjust the connection between the water inlet 3 and the water outlet 5, When the direction is connected, the servo motor 12 is turned on by external control, and the servo motor 12 drives the worm 14 to rotate.

The horizontal bidirectional threaded rod 6 drives the two sets of horizontal bidirectional threaded blocks 7 to move in opposite directions, and the horizontal bidirectional threaded block 7 drives the L-shaped block 8 to move in opposite directions, so that the L-shaped block 8 moves to the inside of the buckle head 9, and the L-shaped block 8 is inserted into the inside of the buckle head 9 to align the heat exchanger body. 4. The installation is completed. Since the L-shaped block 8 is a lateral force, in order to prevent the heat exchanger from shaking, the electric push rod 18 drives the push arm 22 to move, and the push arm 22 drives the push plate 19 to move. The push plate 19 drives the linkage plate 20 to move through the spring 21, so that the linkage plate 20 moves to contact the back of the heat exchanger body 4. The spring 21 provides elastic support for the linkage plate 20, so that the linkage plate 20 gives the heat exchanger body 4 a lateral force to further support and stabilize the heat exchanger body 4.
