Preferably, the number of the first buffering members 220 is four, and the first buffering members 220 are uniformly distributed at four corners of the buffering plate 210, and absorb a part of shock by elastic deformation of the first buffering members 220, thereby reducing the generation of noise.

In order to achieve convenient connection between the buffer plate 210 and the support member 130, in this embodiment, a plurality of bolts 211 are disposed between the support member 130 and the buffer plate 210, each bolt 211 is threaded with a nut 212 located above the buffer plate 210, a plurality of first buffer members 220 are sleeved on the corresponding bolts 211, and the first buffer members 220 are located between the buffer plate 210 and the support member 130. Specifically, the number of bolts 211 is four. The first buffer 220 is in a pre-compressed state under the clamping of the support 130 and the buffer plate 210. By providing a scheme in which the nut 212 is engaged with the bolt 211, not only the buffer plate 210 and the support 130 can be coupled together, but also the pressing force between the buffer plate 210 and the support 130 can be adjusted by tightening or loosening the nut 212, and at the same time, the replacement of the first buffer 220 is facilitated.

In the above-described embodiment, a spacer (not shown) is provided between each nut 212 and the buffer plate 210.

Further, a first pressure area 201 and a second pressure area 202 are formed between the supporting member 130 and the buffer plate 210, the first pressure area 201 is close to the output end of the driving member 110, and the second pressure area 202 is far away from the output end of the driving member 110; a second buffer 230 and a third buffer 240 are provided between the supporting member 130 and the buffer plate 210, the second buffer 230 being located in the region of the first pressure region 201, and the third buffer 240 being located in the region of the second pressure region 202; the cross-sectional area of the second buffer 230 is greater than the cross-sectional area of the third buffer 240, and the thickness of the second buffer 230 is greater than the thickness of the third buffer 240.
