Telescopic rod structure for linear actuator, has fastening ring that is removably attachable on head of telescopic rod such that locating hole for holding sleeve is partially covered, where through hole is provided at circumference of ring

摘要

The structure has a telescopic rod (11) provided, where a radial locating hole is provided at the telescopic rod. A sleeve is formed as a hollow tube body, where the sleeve is insertable in the radial locating hole. A fastening ring (3) is removably attachable on a head of the telescopic rod in such a manner that a locating hole for holding the sleeve is partially covered. A through hole (311) is provided at a circumference of the fastening ring, where the through hole overlaps with the radial locating hole.
