PROBLEM TO BE SOLVED: To provide a liquid spray device in which the setting of direction of an injection pipe can freely be performed at the hand side of a worker, and further the portal type injection pipe capable of reliably preventing the unexpected rotation of the injection pipe is rotatably suspended at the tip of a rod with a vertical axis as a fulcrum.SOLUTION: There is provided a liquid spray device in which a nozzle 9 for injecting liquid and an injection pipe 6 with a connecting shaft 8 attached to a portal type pipe 7 are suspended on a tip of an operation rod 2 so as to permit rotation centering on the connecting shaft 8. The liquid spray device is additionally provided with: a slider 12 slidably mounted in an outer circumference of the rod 2; a lock fixture for fixing the slider to the rod in each position of the slide; a connector 14 fixed to an outer circumference of the injection pipe 6; and a rotational operation tool 4 of the injection pipe with a link 15 where one end is swingably connected to the slider 12 and the other end is swingably connected to the connector 14, in a pivot shaft, respectively.SELECTED DRAWING: Figure 1 |
