[0002] General machinery plays an important role in various fields of the national economy and urban infrastructure construction. They provide equipment and services for oil and natural gas development and gathering, petrochemicals, chemicals, coal chemicals, fertilizers, electricity, metallurgy, non-ferrous metals, energy conservation, environmental protection, coal and other mineral development and utilization, aerospace, shipbuilding and marine engineering, water conservancy, building materials, light industry, textiles, medicine, agriculture, food, transportation and other industries.

[0003] In the prior art, for some mechanical equipment, it is often necessary to set shock-absorbing devices at the four corners of the lower end of the mechanical equipment to prevent the vibration generated during operation from causing damage to the equipment. These shock-absorbing devices generally consist of a shock-absorbing cylinder and a spring to play a shock-absorbing role, and can be adjusted. The shock-absorbing effect of the shock-absorbing device can be adjusted by compressing the spring to different degrees. However, a mechanical equipment usually has at least four shock-absorbing devices at the four corners. When the spring fatigue needs to adjust the tension of the spring, it is very troublesome. Therefore, in order to address this problem, it is necessary to improve a shock-absorbing device for general mechanical equipment processing. Utility Model Content
