[0031] Specifically, the clamping member comprises an L-shaped clamping rod 34 arranged in the notch 33, two connecting shafts 35 are rotatably connected to the L-shaped clamping rod 34, one of the connecting shafts 35 is fixedly connected in the notch 33, and the other connecting shaft 35 is fixedly connected in the sliding groove 36, the L-shaped clamping rod 34 is used to clamp and fix the four edges of the power unit 2, and the connecting shaft 35 is used to support the L-shaped clamping rod 34.

[0032] Further, the power unit 2 is arranged on the lower pressing plate 32, the spring 31 is provided with a plurality of, the notch 33, the L-shaped clamping rod 34, the connecting shaft 35 and the sliding groove 36 are all provided with a plurality of and are arranged in a circumferentially uniform distribution.

[0033] As can be seen, after the power unit 2 is loaded through the upper part of the device and the gap 111, the power unit 2 is placed on the pressing plate 32, the spring 31 is tightened, and the pressing plate 32 is pressed down under the gravity of the power unit 2. Since the L-shaped clamping rods 34 are rotatably connected in the notches 33 through a connecting shaft 35 and rotatably connected in the sliding grooves 36 through another connecting shaft 35, the multiple L-shaped clamping rods 34 are driven to rotate in the opposite direction on the receiving frame 12 with the pressing down of the pressing plate 32, and the ends of the multiple L-shaped clamping rods 34 are tightly attached to the four sides of the power unit 2, so as to clamp and fix the four sides of the power unit 2, complete the installation, and provide damping for the power unit 2 under the action of the spring 31.

[0042] Multiple noise reduction assemblies 4 are provided. The noise generated during the operation of the device is absorbed by the sound-absorbing holes 43 in the surface 41 and the substrate 42. During the propagation of the sound wave in the noise reduction assembly 4, the sound wave will rub against the substrate 42, the sound-absorbing anvil 44, and the tiny particles and channel walls inside the sound-absorbing cotton 45. This friction will consume the energy of the sound wave and convert it into heat energy. As the sound wave continuously propagates and scatters inside the material, its energy will gradually decrease until it is eventually exhausted, achieving the effect of noise reduction. The device can effectively absorb, isolate, or reflect the noise generated during operation, thereby reducing noise pollution and providing a quieter and more comfortable working environment for the staff. In addition, it helps to reduce the potential threat of noise to the staff's hearing and protects their hearing health.
