[0002] The screw fixing seat is a mechanical component used to fix and support the screw. It is widely used in various mechanical devices, such as machine tools, automation equipment, measuring instruments, etc. It is an important component for the precise control of movement in these devices. The main functions of the screw fixing seat include providing a stable support point for the screw, ensuring that the screw will not move or vibrate unnecessary during operation, and being able to withstand the axial and radial loads transmitted by the screw, ensuring that the screw can still maintain its accuracy and stability when bearing loads.

[0003] In order to reduce the wear of the screw rod and the axial hole on the fixed seat, a rotating sleeve that cooperates with the screw rod is usually installed in the axial hole of the fixed seat, so that the screw rod rotates in the rotating sleeve to avoid the screw rod directly rotating in the axial hole of the fixed seat and causing wear on the fixed seat, so that the gap between the screw rod and the axial hole of the fixed seat gradually increases and reduces the accuracy and stability of the system; but since screw rods of different diameters require rotating sleeves of different diameters to cooperate with them, it is not convenient to install rotating sleeves of different diameters on the existing screw rod fixing seat to facilitate use with screw rods of different diameters, avoiding the need to use different screw rod fixing seats when installing screw rods of different diameters, and has low practicality.
