[0035] The copper tube mechanism 1 comprises an inner tube body 101, and a plurality of reinforcing blocks 102 are fixedly arranged on the outer end surface of the inner tube body 101, and the reinforcing blocks 102 are used to improve the strength of the copper tube mechanism 1, thereby improving its service life, and an outer tube body 103 is fixedly sleeved between the outer end surfaces of the plurality of reinforcing blocks 102;

[0036] The connecting sleeve mechanism 2 includes a connecting sleeve body 202, two threaded columns 208, four arc plates 205 and two outer plates 204. The inner wall of the connecting sleeve body 202 is embedded with sealing sleeves 201 at both sides to improve the sealing between the connecting sleeve mechanism 2 and the copper tube mechanism 1. The inner wall of the connecting sleeve body 202 is fixed with a filter screen 211 at the middle position to filter the medium flowing through the inner wall of the copper tube mechanism 1. The upper end face and the lower end face of the connecting sleeve body 202 are both provided with threaded holes 213 at the middle position to insert the copper tube mechanism 1 into the inner wall of the connecting sleeve mechanism 2. The sealing sleeve 201 fits the outer end surface of the outer tube body 103, so that the sealing between the connecting sleeve body 202 and the copper tube mechanism 1 is better. The top plate 209 is held and the threaded column 208 is rotated to squeeze the outer plate 204, so that the arc plate 205 is driven by the connecting block 207 to press against the outer end surface of the outer tube body 103, making it easier to fix the copper tube mechanism 1. The filter screen 211 filters the flowing medium to reduce the possibility of impurities. A reinforcing block 102 is provided between the outer tube body 103 and the inner tube to make the copper tube mechanism 1 stronger and extend its service life.

The copper tube mechanism 1 is pressed on the abutting ring blocks 212, which makes it more convenient to fix the copper tube mechanism 1.

[0039] Working principle: insert the copper tube mechanism 1 into the inner wall of the connecting sleeve mechanism 2, and the sealing sleeve 201 fits the outer end surface of the outer tube body 103, so that the sealing between the connecting sleeve body 202 and the copper tube mechanism 1 is better, hold the top plate 209 and rotate the threaded column 208 to squeeze the outer plate 204, so that the arc plate 205 is driven by the connecting block 207 to press the outer end surface of the outer tube body 103, making it easier to fix the copper tube mechanism 1, and the copper tube body is against the ring block 212, so that the copper tube will not be directly attached to the filter screen 211, and the filter screen 211 filters the flowing medium to reduce the possibility of impurities. The filter screen 211 is fixed to the inner wall of the connecting sleeve by the embedded ring 210 and will not loosen and fall off. A reinforcing block 102 is provided between the outer tube body 103 and the inner tube to make the copper tube mechanism 1 stronger and extend its service life.
