[0030] Working principle:

[0031] First, the screw body 6 is installed through the mounting hole 5, so that the two ends of the screw body 6 are accurately fixed inside the fixed ring 35. The fixed ring 35 not only stabilizes the position of the screw body 6 and prevents it from being eccentric and shaking, but also ensures that the lubricating ball 34 is in stable contact with the screw body 6, preparing for subsequent lubrication. At the same time, the coupling 61 on one side of the screw body 6 is used to connect an external power source to provide power for the rotation of the screw body 6. When the device starts to run, the screw body 6 begins to rotate, and the sliding groove 62 on its surface provides guidance and limiting for the movement of the screw nut 7. The sliding ball 72 at the position corresponding to the sliding groove 62 of the screw nut 7 greatly reduces the friction between the screw nut 7 and the screw body 6 by virtue of its rolling characteristics, enabling the screw nut 7 to move smoothly and efficiently along the screw body 6, achieving precise transmission and ensuring the stability and accuracy of the device operation. At the same time, the fixed assembly 2 between the support base 11 and the fixed base 12 and the base 1 plays a key role in the process of device operation. The spring 24 uses its elasticity to buffer the hard impact caused by the vibration of the device, reducing the damage of the vibration to the components. The round washer 23 disperses the pressure to protect the spring 24, and the bolt 21 and the screw 22 ensure stable connection. At the same time, the rubber pad 4 further absorbs the impact force from all directions, blocking the transmission of vibration between the support base 11, the fixed base 12 and the base 1, and the two work together to ensure the stability of the entire support frame structure. In addition, the oil storage chamber 31 is the core area for storing lubricating oil. When the device is running, the lubricating oil flows into the storage groove through the oil outlet pipe 33, infiltrates the lubricating ball 34, and the lubricating ball 34 forms a good rolling contact with the surface of the screw body 6, reducing the friction coefficient and reducing the friction loss between the components. The user can also directly observe the amount of lubricating oil in the oil storage chamber 31 through the viewer 32. When the lubricating oil is insufficient, the sealing cover 36 at the oil inlet of the top of the oil storage chamber 31 is unscrewed to replenish it. The sealing cover 36 is connected by threads to ensure the sealing of the oil storage chamber 31 and prevent impurities from entering. The sealing pad 71 on the front side of the screw nut 7 blocks dust, impurities and other foreign matter from entering the meshing area of the screw body 6 and the screw nut 7, ensuring the purity and stability of the transmission. Thus, the entire work flow is completed.
