[0024] Referring to Figure 1 , 2 , the spraying structure 7 comprises an oil pump 71, a nozzle 72 and a connecting pipe 73, the oil pump 71 is fixed and communicated with the storage tank 2; the nozzle 72 is transversely moved on the rack 1 through the control structure 4 connected to the handrail 3.

[0025] Referring to Figure 1 , 2The control structure 4 includes a control slide rod 41, a telescopic rod 42, a drive rod 43, and a support shaft 44. The control slide rod 41 is laterally slidably connected to the handrail 3 on one side corresponding to the spraying structure 7. The control slide rod 41 extends vertically, which is more in line with the ergonomic design, which is conducive to pushing the frame forward and also facilitates the left and right movement of the control slide rod 41. One end of the telescopic rod 42 is rotatably connected to the control slide rod 41, and the other end extends toward the spraying structure 7. One end of the drive rod 43 is sleeved and slidably connected to the telescopic rod 42. In accordance with the radius change during the rotation process, the other end extends to the spraying structure 7. The support shaft 44 is fixed to the frame 1 and passes through the end of the drive rod 43 near the spraying structure 7. The drive rod 43 rotates laterally along the support shaft 44.

[0026] Reference Figure 1 , 2 The nozzle 72 is fixed below the front end of the drive rod 43, forming a force-saving lever; one end of the connecting pipe 73 is connected to the nozzle 72, and the other end is connected to the storage box 2; when the control slide bar 41 is slid left and right at the rear end of the frame 1, the front nozzle 72 can be adjusted to the left and right position.

[0027] Reference Figure 1 , 2 The frame 1 has a rotatably connected covering structure 5 on its side wall.
