摘要

The tool set contains a bell spanner (1) with a radially inward projecting ring (2) at the bottom. The ring has apertures (3) corresponding to the abutment cams (17) of the screwed hood. The spanner has a central polygonal seat (4) in the top, which engages over the meter cartridge. A ratchet (5) has a polygonal part (6) corresponding to the polygonal seat, a ring hook (9) at one end, and an open-jawed spanner (7) at the opposite end. There is also an anti-turning locking spanner (20) with a grip (21). The polygonal part or seat may have an extension part (8).
