[0002] The lead screw, also known as the screw, is one of the most commonly used transmission components in tool machinery and precision machinery. The lead screw has the characteristics of high precision, reversibility and high efficiency. It is widely used in various industrial fields. When in use, a protective cover is needed to protect it, keep the lead screw clean, reduce wear and damage, help the lead screw maintain a good working condition, and extend its service life.

[0003] Most screw rod protective covers cannot accurately follow the movement of the screw rod, so that the protective cover may be offset, resulting in incomplete protection and affecting the protection effect; during the movement of the screw rod, the protective cover may be damaged by a large impact force, thereby accelerating the aging and damage of the protective cover and shortening its service life. Therefore, the utility model provides a multi-section screw rod protective cover to solve the problems raised in the above background technology. Utility Model Content

The fixed block is arranged by being clamped with a clamping block, so as to drive multiple clamping rods to move, so that the protective sleeve can slide smoothly during the movement of the screw rod, avoiding shaking and deviation, and enhancing the protective effect. When the upper clamping rod moves downward to the limit distance, multiple damping springs absorb the impact force through a baffle fixed at the upper end, thereby playing a buffering role, reducing the damage of the protective sleeve caused by the impact, thereby slowing down the aging of the protective sleeve and extending the service life of the protective sleeve.
