As shown in fig. 4 and 5, the positioning plate 152 is provided with a mounting hole 1523, the mounting hole 1523 is a through hole, and a supporting rod 1524 is disposed in the mounting hole 1523; the inner end of the abutting rod 1524 can push the corresponding movable half cylinder 1522 to move, so that the movable half cylinder 1522 can cooperate with the fixed half cylinder 1512 to form a cylinder structure. Threads are arranged on the movable half cylinder 1522, the fixed half cylinder 1512 and the lifting rod 1532, and when the movable half cylinder 1522 is matched with the fixed half cylinder 1512, the cylinder structure is matched with the lifting rod 1532 in a threaded manner, so that the corresponding lifting rod 1532 is locked; namely, the internal threads on the moving half cylinder 1522 and the fixed half cylinder 1512, which mainly serve to lock the lifting rod 1532, thereby enabling the cylinder structure to more reliably lock the lifting rod 1532.
In order to facilitate the operation, an abutment spring 1526 is sleeved on the abutment rod 1524, and the abutment spring 1526 enables the abutment rod 1524 to push the corresponding movable semi-cylinder 1522 to move, so that the movable semi-cylinder 1522 is kept in an abutting state with the fixed semi-cylinder 1512, and at this time, the movable semi-cylinder 1522 and the fixed semi-cylinder 1512 form a complete cylinder structure. Specifically, a U-shaped mounting plate 1525 is disposed at the outer end of the mounting hole 1523, the mounting plate 1525 is fixedly connected with the positioning plate 152, and a through hole is disposed on the mounting plate 1525, and the abutting rod 1524 passes through the through hole and the mounting hole 1523; one end of the abutting spring 1526 is connected to the abutting rod 1524, and the other end is connected to the mounting plate 1525.

The inner end of the abutting rod 1524 abuts against the connecting rod 1529, thereby pushing the two moving half cylinders 1522 to move by pushing the connecting rod 1529 to move.
Further, a tension spring 154 is disposed between the middle of the connecting rod 1529 and the middle of the bar-shaped groove 1527, and when the abutting rod 1524 is separated from the connecting rod 1529, the tension spring can pull the connecting rod 1529 to move away from the fixed semi-cylinder 1512, so that the movable semi-cylinder 1522 is separated from the fixed semi-cylinder 1512, and the locking of the lifting rod 1532 is released. The elastic force of the tension spring 154 is smaller than that of the abutting spring 1526, so that in a natural state, the elastic force of the abutting spring 1526 can overcome the elastic force of the tension spring 154; so that the abutment rod 1524 can push the connection rod 1529, thereby holding the movable half cylinder 1522 and the fixed half cylinder 1512 in abutment with the corresponding lifting rod 1532, thereby locking the lifting rod 1532.
Preferably, the cross sections of the movable half cylinder 1522 and the fixed half cylinder 1512 are smaller than 1/2, so that a gap can be reserved between the movable half cylinder 1522 and the fixed half cylinder 1512, and the movable half cylinder 1522 and the fixed half cylinder 1512 can apply a larger clamping force to the corresponding lifting rod 1532 under the action of the abutting rod 1524, so as to fix the lifting rod 1532 more reliably.

in use, the bottom plate 17 of the adapter device 1 is mated with the bottom of the mounting plate 1525 and the steps in the connecting tube 11 are brought into abutment with the ends of the connector tube 21. When the abutting rod 1524 is then manually pulled away from the connecting rod 1529, the tension spring 154 can pull the connecting rod 1529 away from the fixed half cylinder 1512, thereby releasing the locking of the lifting rod 1532. The height of the lifting rod 1532 is adjusted according to the actual thickness of the mounting plate 1525 so that the lower end of the moving rod just fits the side wall of the cooling joint 2 boss; the abutment rod 1524 is then released such that the lifting bar 1532 is locked. Finally, the threaded rod 13 is rotated to enable the moving assembly 15 to move towards the direction approaching the fixed plate 12, so that the switching device 1 can clamp and fix the cooling joint 2, and then the nut 16 is screwed; at this time, the assembly of the adapter 1 with the mounting plate 1525 is completed.
