In terms of use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a buffer component 5 is added to the application document.

[0026] More specifically:

[0027] like Figure 1-Figure 4 As shown:

[0028] A buffer assembly 5 is installed on the base plate 1, and the buffer assembly 5 includes a first baffle 501, a second baffle 502, a third baffle 503 and a fourth baffle 504 which are fixed sequentially on the upper surface of the base plate 1.
