The frictional traction of the weft yarn by water jet insertion is greater than that by air jet insertion, and the diffusion is small. It is suitable for the weft insertion of smooth-surfaced synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. In addition, the water jet weft consumes less energy and has the lowest noise.

In addition, through the setting of the elastic spring, air will not enter from the water outlet pipe when pumping water, thereby ensuring that the atmospheric pressure in the cylinder body is small.

The rocker 14 can drive the piston 7 to move through the moving trajectory of the rotating shaft 13, and the rocker 14 is rotatably connected to one side of the rotating shaft 19.

[0024] As a technical optimization scheme of the utility model, a water inlet assembly 15 is fixed on one side of the cylinder body 2, and the water inlet assembly 15 includes a water inlet pipe 16, which is fixed on one side of the cylinder body 2. A water inlet hole 17 is opened at the end of the water inlet pipe 16, and a rotating shaft 3 18 is fixed inside the water inlet pipe 16. The rotating shaft 3 18 serves to limit the movement of the sealing plate 20. A torsion spring 19 is sleeved on one side of the rotating shaft 3 18. One end of the torsion spring 19 is fixed in the rotating shaft 3 18, and the other end is fixed in the sealing plate 20.

One side of the torsion spring 19 is rotatably connected to the sealing plate 20, and one side of the water inlet pipe 16 is sleeved with a pumping pipe 21.

[0025] As a technical optimization scheme of the utility model, a water outlet assembly 22 is fixed at the end of the cylinder body 2, and the water outlet assembly 22 includes a water outlet pipe 23. A water outlet hole 24 is opened at the end of the water outlet pipe 23. A guide rod 25 is fixed inside the water outlet pipe 23.

At the same time, under the action of water pressure, the water pressure will push the blocking plate 28, thereby moving the blocking plate 28, and then the water will flow from the water outlet hole 24 into the connecting pipe 29 through the gap between the blocking plate 28 and the water outlet pipe 23, and finally enter the nozzle.
