[0023] The overall effect achieved by the entire Embodiment 1 is that through the setting of the first outer housing 4, and the material of the first outer housing 4 is glass wool material, and the glass wool material can absorb sound waves, reduce noise, and also has a certain protective effect. Through the setting of the shock-absorbing structure 13, the effect of shock-absorbing the first outer housing 4 is achieved, thereby achieving the effect of shock-absorbing the entire device.
[0024] Embodiment 2, as Figures 1-4As shown in the figure, the shock absorption structure 13 includes an inner cavity 1301 opened at the top end of the support leg 10. A spring 1302 is fixed on the inner bottom wall of the inner cavity 1301. The top end of the spring 1302 is fixed with a connecting block 1303. The top end of the connecting block 1303 penetrates through the support leg 10 and is fixed to the first outer housing 4. A damper 1304 is installed inside the spring 1302 between the connecting block 1303 and the inner bottom wall of the inner cavity 1301. Limiting blocks 14 are fixed on the outer walls at both ends of the connecting block 1303. Limiting grooves 15 matching the limiting blocks 14 are opened at both ends of the inner cavity 1301 in the support leg 10. A bracket 11 is fixedly connected to the bottom ends of the two support legs 10. A plurality of mounting holes 12 are opened in the bracket 11.
