The main body 1 comprises: a connecting pipe 101 arranged at the middle position of one end of the main body 1, and a clamping groove 102 is arranged inside the main body 1 to facilitate the installation and use of the joint structure.

[0028] Please refer to Figure 2 and Figure 3 A connecting groove 2 is provided at one end of the connecting pipe 101 close to the main body 1, and a rubber sealing ring 201 is provided inside the connecting groove 2.

A bidirectional screw 204 is provided on one side of the clamping groove 102 and penetrates into the two groups of clamping blocks 202. The two groups of clamping blocks 202 can be adjusted toward each other through the bidirectional screw 204. A limiting rod 205 is provided on the side of the clamping groove 102 away from the bidirectional screw 204 and penetrates into the two groups of clamping blocks 202. The adjustment of the two groups of clamping blocks 202 is more stable through the limiting rod 205. A fixing groove 206 is provided at one end of the connecting pipe 101 away from the connecting groove 2, and a water-passing groove 207 is provided at one end of the fixing groove 206 and penetrates into the inside of the connecting groove 2. The fixing groove 206 is connected to the connecting groove 202 through the water-passing groove 207.

[0029] Please refer to Figure 1 and Figure 2 A guide ring 301 is provided at one end of the pipe joint 3 close to the clamping groove 102. The cooperation between the guide ring 301 and the two sets of clamping plates 202 facilitates the installation of the water nozzle 302. The end of the guide ring 301 away from the pipe joint 3 is provided with a water nozzle 302 that penetrates into the connecting groove 2.

[0030] Please refer to Figure 2 and Figure 3, the two sets of clamping blocks 202 are movably connected to the main body 1 through the clamping groove 102, which is convenient for adjusting the two sets of clamping blocks 202. One end of the connecting tube 101 is welded to one end of the main body 1. A bearing is provided on one side of the bottom end of the clamping groove 102, and the bottom end of the bidirectional screw 204 penetrates into the bearing. The bidirectional screw 204 is rotatably connected to the main body 1 through the bearing. The rotation of the bidirectional screw 204 is more stable through the bearing. The two ends of the limit rod 205 are respectively welded to the top and bottom ends inside the main body 1. The top of the bidirectional screw 204 is provided with a rotating block, which is convenient for rotating the bidirectional screw 204. One end of the two sets of clamping blocks 202 is provided with a matching bidirectional screw 204. The two sets of clamping blocks 202 are threadedly connected with the bidirectional screw 204 through the threaded holes, which plays the role of limit adjustment, so that the two sets of clamping blocks 202 can be adjusted towards each other. A limit hole is set at the other end of the two sets of clamping blocks 202, and the two sets of clamping blocks 202 are slidably connected with the limit rod 205 through the limit hole. The two sets of clamping blocks 202 and the limit rod 205 can slide through the limit hole, so that the adjustment of the two sets of clamping blocks 202 is more stable. The rubber sealing ring 201 is detachably connected to the connecting pipe 101 through the connecting groove 2, and the rubber sealing ring 201 can be installed in the connecting groove 2 for installation and use, and the sealing between the rubber sealing ring 201 and the faucet 302 and the connecting groove 2 is better.

[0031] Please refer to Figure 1 and Figure 2 The water nozzle 302 is fixedly connected to the pipe joint 3 through the guide ring 301, and the water nozzle 302 and the pipe joint 3 are fixed through the guide ring 301. The mutual cooperation between the guide tube 301 and the two groups of clamping blocks 202 makes the installation sealing between the water nozzle 302 and the joint structure better. The water nozzle 302 is detachably connected to the connecting pipe 101 through the connecting groove 2, which makes it easy to clamp the water nozzle 302 into the inside of the connecting groove 2.

[0032] Working principle: Before using the utility model, the connecting pipe 101 is connected to the water inlet pipe of the liquid cooling plate through the fixing groove 206, and the pipe joint 3 is connected to the water outlet of the external water pipe. When in use, the water nozzle 302 is clamped into the inside of the connecting groove 2, and the rotating block is rotated with a wrench to drive the bidirectional screw 204 to rotate. The bidirectional screw 204 cooperates with the threaded holes inside the two sets of clamping plates 202 to adjust the two sets of clamping plates 202 towards each other. The two sets of clamping plates 202 can be adjusted to the limit rod 205 through the limit hole. When the two sets of clamping plates 202 are movable, the adjustment of the two sets of clamping plates 202 is more stable, and the inclined groove 203 of the clamping plates 202 contacts the guide ring 301. As the two sets of clamping plates 202 are adjusted toward each other, the two sets of clamping plates 202 squeeze the guide ring 301 through the inclined groove 203, so that one end of the water nozzle 302 is in close contact with the rubber sealing ring 201, so that the sealing between the water nozzle 302 and the connecting groove 2 is better, thereby making the sealing effect between the joint structure and the water nozzle 302 better, which is convenient for the air tightness test of the liquid cooling plate.
