Spanner to be used in awkward spaces, comprising chain guided around rotating drives

摘要

The spanner is assembled of a metal pipe with a tool head (2, 3) on both ends and a chain (6) guided around sprockets (4, 5) fixed to the rotating drives (7, 8) which can be provided with a socket or any other suitable tool as required. The pipe part can be divided into two sections (10, 10') joined and adjusted in length with treaded areas (11) at their ends pointing towards each other. The chain lock is accommodated inside the space in one of the tool heads (2, 3) which can be closed with a screw-on lid.
