"Cutting scissors, preferably for electrical line, cables with larger cross-sections * "

The invention time regards "b itself, in a novel Sohneidschere preferably for electric cable of larger cross _sciuai?"

This Soherenkonstruktion has due to the arrangement and Training of their translated actuating organs for the movable one Cutting jaws have a very considerable cutting force, so that also, strong Zabel or the like, such as # also plastic- and aluminum strips with relatively little effort

Pig · 1 the cutting scissors with closed

Handle parts and open cutting jaws for inserting the food and

Fig. 2 share the cutting scissors with the handle open and compressed cutting jaws after the end of the cutting process.

According to the drawing, 1 is a of the fixed handle part to the fixed cutting jaws 1 "On the back of the bolt 3 is equipped with a toothed segment 5 dies 2 rotatably supported against d.er action of tension spring 15 °. On the bolt 6, the gear 7 is disposed, which is engaged with the ring gear 5 i ⁿ intermeshing connection. The actuation of this gear takes place in the course of the hatching movements of the movable handle part 12 via the ratchet cam 9, which, depending on the position of the handle lever 12, engages with the gear 7 or disengages with the same. Io, Io a is an angled retaining cam, the engagement of which in the toothed wheel 7 is also controlled by the respective position of the movable handle part 12. 11 is the pin for this restraint. 3.6 and I7 are scalloped abutments for notching the ratchet cam $ and to limit its movement.13 is a spring for spreading the handle parts 1a and 12j which are releasably connected to one another by a Megel 14 against the action of this spring.

_[ Λ _β

The ratchet cam 9 and the retaining cam Io are arranged and designed in such a way that they reciprocally engage in the teeth of the gear 7 in such a way that "when the handle parts la, 12 of the ratchet 9 are spread over the teeth of the gear 7 blocked by the retaining cam Io" J latches away while, on the other hand, when the handle parts are pressed together, the retaining hook Io is released and engages in the next following tooth by placing itself against the lower stop 17. This releases the gear wheel 7 so that the movable clamping jaw 2 can be opened by the tension spring 15 to insert the material to be cut ratchet cams 9 now engaging gear 7 and gear segment 5 &&? Cutting jaws for the purpose of cutting through the cable 4 ratcheted in the viewing position. At this Yorgang the back holding cam Io is with us again. the gear 7 in meshing connection »
