[0029] Working principle: Embodiment

[0030] For a narrow space use environment, the T-shaped connecting pipe 42 in each of the two adapter pipes 4 can be twisted, so that the T-shaped connecting pipe 42 drives the corresponding second transition pipe 5 to rotate and adjust synchronously under the support of the corresponding adapter pipe head 41, until a suitable position without structural interference is reached, thereby providing a convenient installation condition for the subsequent existing cooling pump device.

[0031] During the rotation of the T-shaped connecting pipe 42, the positioning rod 44, the first buffer spring 45 assembly and the inner wall friction of the adapter pipe head 41 need to be overcome. After the T-shaped connecting pipe 42 is rotated and adjusted to a suitable position, the positioning rod 44, the first buffer spring 45 assembly and the inner wall friction of the adapter pipe head 41 can also ensure the stability of the adjusted T-shaped connecting pipe 42 and second transition pipe 5. Embodiment

[0032] For the whole device storage or transportation, after the cooling pump delivery device is separated from the two second transition pipes 5, the T-shaped connecting pipe 42 inside the two adapter pipe fittings 4 is screwed, and then the T-shaped connecting pipe 42 drives the respective corresponding second transition pipe 5 to overturn, until the second transition pipe 5 is sleeved between the two limiting arc pressing plates 64 in the corresponding limiting assembly 6, and the same reason, the positioning rod 44, the first buffer spring 45 assembly and the friction force between the inner wall of the adapter pipe head 41 need to be overcome in the rotation process of the T-shaped connecting pipe 42, and after the T-shaped connecting pipe 42 is rotated and adjusted to the appropriate position, the friction force between the positioning rod 44, the first buffer spring 45 assembly and the inner wall of the adapter pipe head 41 can also ensure the stability of the adjusted T-shaped connecting pipe 42 and the second transition pipe 5;

[0033] Then, the elastic force of the two second buffer springs 63 inside the limiting assembly 6 is used to make the two limiting arc pressing plates 64 and the two limiting support rods 62 inside the limiting assembly 6 form a clamping structure to clamp and limit the corresponding second transition pipe 5, so as to ensure the storage effect of the second transition pipe 5, and the other second transition pipe 5 is also operated according to the above steps.
