One end of the second diversion pipe penetrates out of the liquid storage tank and is connected with a third diversion pipe. A guide seat is fixedly connected to the workbench and located below the first clamping frame. A rotating frame is slidably arranged on the guide seat. Symmetrically distributed clamping rings are arranged on the rotating frame. Fixing bolts are arranged on the clamping rings in a threaded manner. A spray paint bottle is clamped inside the clamping rings. The spray paint bottle is communicated with the adjacent third diversion pipe. A first connecting rod is fixedly connected to the rotating frame. A guide frame for guiding the first connecting rod is arranged on the workbench. A second connecting rod is fixedly connected to the first connecting rod. A handwheel is arranged on the second connecting rod.

[0008] As a further preferred solution, both the second diversion pipe and the third diversion pipe are flexible hoses.
