The lifting pressure ring 204 is connected to the two second docking blocks 203 in a vertically sliding manner. Two fixed sliding plates 207 are symmetrically formed on the outer wall of the lifting pressure ring 204. The two fixed sliding plates 207 are respectively fixedly connected to the two positioning clamping plates 202. Lifting sliding grooves for the vertical sliding of the lifting pressure ring 204 and the fixed sliding plates 207 are provided on the second docking block 203, so as to stably lift the lifting pressure ring 204 and the fixed sliding plates 207.

[0036] Reset components are arranged inside both of the two second docking blocks 203. The reset components are used to push the lifting pressure ring 204 to automatically reset.

[0042] After that, release the lifting pressure ring 204. At this time, the spring 209 pushes the lifting pressure ring 204 and the fixed slide plate 207 to slide back to their original positions through rebound. At the same time, the positioning card plate 202 drives the first docking block 201 to be clamped and inserted under the drive of the fixed slide plate 207, so as to clamp and lock the first docking block 201, so as to facilitate the efficient replacement of the liquid spray head 4.
