The two sliders 224 are respectively slidably connected to the two sliding grooves 206;

[0030] When the movable blocks 222 slide along the upper U-shaped rod 215, the sliders 224 are driven to slide in the sliding grooves 206, ensuring the stability of the movement of the movable blocks 222;

[0031] A top plate 210 located between the two movable blocks 222 is fixedly connected to the top of the first mounting frame 201.

[0034] Working principle: When in use, first insert the two positioning rods 204 into the two positioning holes 205 respectively until the two sealing rings 207 are in contact with each other. Then slide the guide plate 214 upward along the guide post 219, drive the two movable blocks 222 to slide along the upper U-shaped rod 215 respectively through the two connecting rods 217. At the same time, the two insertion rods 216 approach each other. Then slide the sliding plate 211 upward along the lower U-shaped rod 213 to drive the lower insertion plate 212 to rise until it is inserted into the bottom groove 209. At the same time, both side plates 203 rise. Then slide the guide plate 214 downward along the guide post 219 to drive the two insertion rods 216 to move away from each other until they are respectively inserted into the two jacks 223 to support and limit the two side plates 203. Then rotate the turntable 221 clockwise. Since the screw barrel 218 is threadedly sleeved outside the screw rod 226, the screw barrel 218 moves downward while rotating until it abuts against the guide plate 214, completing the limitation of the guide plate 214 to prevent the lower insertion plate 212 from disengaging from the bottom groove 209, and connecting and fixing the first installation frame 201 and the second installation frame 202, thus completing the quick docking of the first pipeline 1 and the second pipeline 3;

[0035] When the guide plate 214 slides downward along the guide post 219 so that the two insertion rods 216 are respectively inserted into the two jacks 223, at the same time, the upper insertion plate 225 descends and is inserted into the top groove 208. Then the guide plate 214 is limited by the screw barrel 218 to prevent the upper insertion plate 225 from loosening. Finally, the firm docking of the first pipeline 1 and the second pipeline 3 is completed.
