Carrying handle for electric instrument e.g surveyor theodolite

摘要

The handle consists of a material with a predetermined temperature coefficient, and is removably fastened to a main casing which consists of a material with a different temperature coefficient of that of the handle. Connecting elements are provided between the main casing and the handle, and devices are formed in a part of the connecting elements, which prevent a transmission of a heat expansion force appearing in the handle at an temperature change of the main casing.
