Description

3. Pliers according to claim 1 and 2, characterized in that the resilient retaining member leads to the fact that the resilient retaining member means that it is now the position intended for it - at least in the areas of the retaining member, for example in the right part of the jaws of the pliers - the cutting leg engaging behind the back lets and shuttles between the jaws of the pliers. (10 b) has an outline shape adapted to this. This results in a partial or complete covering of and at the joint end of the cutting gap between the two cutting flanks in the area in front of the joint block (19) of the pliers, so that the Pliers operator both legs have a twisting crank step, the view of the workpiece is taken.

The subject of this patent are for the end.

-Function, however, two such retaining members- The pliers reproduced in the drawings are required, which are a total of three screws and are formed from two pliers legs 10 and 11, which are held by means of a wire spring. The assembly in the area of a hinge axis 12 scissor-like retaining members therefore requires a large 35 which are connected to one another in a cross manner. On a ί assembly effort and represents an expensive execution side of the hinge axis 12 are the pliers legs 10 tion. In addition, the holding members, which protrude far beyond the Zan and 11 as handle legs 10 a and 11 a, hide the view of the while on the opposite side the joint axis 12 \ workpiece to be cut always and completely, so both legs as cutting legs 10b and 11b that such a pair of pliers for work in which the 40 are performed.

A clear view of the work space is essential, over- * The cutting legs 10b and Ub have a substantial wedge-shaped cross-section, and the holding device proposed according to the invention leave an inner-shaped space between them, which cannot be used at all. The member meets the requirements of practice in cutting leg 10 b is a fixed member 13 to-; highly advantageous, because the retaining 45 is now in an orderly manner, which is able to clamp on the inclined surface 14 facing the wedge-shaped member over the entire length tLs the space of the cutting leg and the cut off rests and protrudes into the area of the cutting edge 15.

On the other hand, the support or clamping face member facing the cutting edge 15 is always fixed in such a way through the double bearing in the edge 16 runs over its entire length and transverse link area and on the other hand in the insulating sheath cutting thickness parallel to the likewise inclined, that it remains in contact with the corresponding inner surface 17 of the cutting leg, which is indicated to be cutting, even if any- 55 I ^{1 b} - This results in a cut wire end 18 anyway

For what reasons the screw should be kept loosened in the joint securely. As a result, the retaining member 13 can now be seen in the area of the 'tion from above, the area of the pliers cutting leg 106, with a cutting edge that is adapted to this, which makes it easier to handle and forms the cutting in front of the joint area 10 much easier.
