The bottom of the inner wall of the liquid medicine tank 301 is fixedly connected with the water pump 303. The bottom of the water pump 303 is fixedly connected with the delivery pipe 304.

[0029] During specific implementation, the bottom of the delivery pipe 304 penetrates through the liquid medicine tank 301 and extends to the outside of the liquid medicine tank 301 and is fixedly communicated with the medicine spraying pipe 305. The bottom of the medicine spraying pipe 305 is fixedly connected with the atomizing nozzle 306. The medicine spraying pipe 305 and the liquid medicine tank 301 are fixedly connected through two stabilizing blocks.

[0030] Specifically, the installation component 4 includes a moving groove 401, a first clamping groove 402, a vertical plate 403, a first clamping block 404, a second clamping groove 405, a fixing plate 406, a sliding groove 407, a sliding rod 408, a sliding plate 409, a bearing, a threaded rod 410, a handle 411, a threaded plate 412, and a second clamping block 413. Two moving grooves 401 are formed at the bottom of the mounting plate 2. The left top of the moving groove 401 is provided with a first clamping groove 402. The left side inside the moving groove 401 is movably connected with a vertical plate 403.
