Problems solved by technology

[0002] The bridge jacks currently used in the market are all special jacks for cars, and there are the following problems in use: 1. The actual jacking force of the bridge jack is less than 1 ton. 2. When the jacking force reaches 1 ton, 30 kg of manpower is required. , the operation is very laborious. 3. When the pressure reaches one ton, the material of the bridge jack itself is too thin, and the balance tooth of the bracket bears too much pressure, which is easy to damage. 4. At present, the performance of the bridge jack is generally used in small vehicles. To the technical index requirements of the jack
