摘要

The irrigation bar has a head (40) in which a rotating plug (30) is mounted. This is operated by a connecting cable (60) whose other end is attached to a connector (18) with a lug (181). The lug lodges in a slit (171) in a sleeve (17) and rotates when the sleeve is rotated. This causes the head to rotate.
