Furthermore, the provision of the second vibration damping assembly 50 plays a further role in reducing the vibration, thereby preventing the vibration from being transmitted to the base through the outer frame structure 31.

[0031] like Figure 1 , Figure 2 , Figure 4 As shown, the first vibration reduction assembly 40 includes a plurality of spring assemblies, and the plurality of spring assemblies are divided into two groups. The two groups of first vibration reduction assemblies 40 are respectively arranged on both sides of the middle frame structure 32, and the first end of each spring assembly is connected to the middle frame structure 32, and the second end of each spring assembly is connected to the first end of the second vibration reduction assembly 50.

[0040] like Figure 5 As shown, the surface of the buffer structure 52 facing the supporting bottom frame 51 is flat, ensuring the reliability of the fit between the surface of the buffer structure 52 facing the supporting bottom frame 51 and the lower surface of the supporting bottom frame 51, thereby ensuring the reliability of the buffer structure 52 in reducing vibration.

[0041] like Figure 5 As shown, the deformation space 5213 is trapezoidal, and the large end side of the deformation space 5213 is arranged close to one side of the outer frame structure 31, and the small end side of the deformation space 5213 is arranged away from one side of the outer frame structure 31. In this way, it is ensured that the deformation space 5213 can provide sufficient deformation space for the buffer body 521, thereby ensuring the reliability of reducing the vibration of the buffer structure 52.
