Description

The invention relates to manual. tool and can be used in various fields of industrial tee during assembly and assembly work. .

The purpose of the invention is to simplify the design and reduce the size.

FIG. 1 shows an Allen wrench, general view, in FIG. 2 is a view A of FIG. 1, in FIG. 3 is a view B in FIG. one.

The face wrench comprises a housing 1 with a hexagonal gap 2, mounted on the housing 1 with rotation of the cap 3, a ball lock 4 located therein, mounted in the housing 1 with axial displacement spring-loaded, pushers 5, at the ends of which extend throat cavity 2, sponges 6, having a different thickness H) cam 7, are rigidly fixed on the inner surface of the krypka 3 and having the ability to interact alternately with the free ends of the pushers 5. In case 1 The sponge 6 is in contact with two adjacent faces of the pharynx 2.

The key works as follows.

To adjust the key, rotate the cap 3, the cam 7 of which alternately
