[0054] There are two second adjustment rotating arms 303, and the guide seat 306 is arranged between the two second adjustment rotating arms 303. A guide plate 307 is provided on the guide seat 306 and close to the second adjustment rotating arm 303. The guide part 308 and the fixing part 309 are arranged on the guide plate 307. The guide part 308 is a curved surface structure, and the fixing part 309 is a groove structure.

[0055] The position of the buffer support device 4 of this embodiment corresponds to the position of the guide plate 307;

[0056] The specific structure of the buffer support device 4 is as follows:

[0057] It includes a buffer mounting seat 401, a buffer spring member 402, a buffer connecting seat 403, a buffer connecting rod 404 and a buffer rotating cylinder member 405. The bottom of the buffer spring member 402 is arranged on the buffer mounting seat 401, and the top of the buffer spring member 402 is connected to the buffer connecting seat 403. There are two buffer spring members 402. The buffer connecting rod 404 is connected to the two buffer connecting seats 403. The buffer rotating cylinder member 405 is sleeved on the buffer connecting rod 404. The buffer spring member 402, the buffer connecting seat 403, the buffer connecting rod 404 and the buffer rotating cylinder member 405 form the buffer support end of the buffer support device 4. The buffer rotating cylinder member 405 can enter the fixed portion 309 through the guide portion 308.

[0058] During the process in which the above-mentioned buffer rotating cylinder member 405 is able to enter the fixed portion 309 through the guide portion 308, the buffer spring member 402 is in a compressed state. At the same time, the two ends of the buffer rotating cylinder member 405 are connected to the buffer spring member 402 through the buffer connecting rod 404 and the buffer connecting seat 403, that is, the buffer support device 4 corresponding to the position of the guide plate 307 has two buffer spring members 402, which reduces the risk of shaking when using a single buffer spring member 402, and ensures the stability of the supporting force of the slope adjustment device 3.

[0059] The running water trough 102 of this embodiment includes a top trough portion 1021, a sloped trough portion 1022 and a bottom trough portion 1023.
