Apparatus for fixing identification tags on animals
BACKGROUND OF THE INVENTION 
     The present invention refers to an apparatus for fixing identification tags on animals. 
     This apparatus is of the pincer type, which carry means for placing the tag on one side and fixing said tag on the ear of the animal, said tag carrying any characteristic or numbering which corresponds to the animal. 
     Apparatus of this type and for the same purpose are already known, with variations being in their characteristics of construction although all of them, once the tag is fixed, have the section (which originally carried the tag) in a fixed position such that, in order to remove the apparatus, one has to effect the operations of first opening the the apparatus and then separating same from the tag. 
     The apparatus of this invention does away with this problem given that, once the tag is fixed and closed on the ear of the animal, the apparatus remains open due to the manner in which it is constructed. 
     SUMMARY OF THE INVENTION 
     The apparatus of this invention, which is of the pincer type, is composed of two sections or &#34;arms&#34; which have, in their central part, a longitudinal gaps, mentioned gaps being connected to each other by metal strips crosswise to each other and interconnected to each other in an overlapping position by a pin situated in their center, one end of each strip on the same side close to the handle of the apparatus, rotating on their axis within the gap due to having corresponding fixed axis of rotation, while the two other opposed ends have, at their extremities, a channel or cut that is &#34;L&#34;-shaped, the internal angle of which is a right angle while the external part is rounded. 
     Each of the &#34;L&#34;-shaped channels has a pin which is located so that, upon rotation of the strips, said strips travel along the longer section of the corresponding &#34;L&#34;-shaped gap with the help of the pin and also the tension of a spring mounted on the central pin of the strips and their rotating ends priorly mentioned. 
     When both pins of the &#34;L&#34;-shaped gap are at the juncture of the two legs of the &#34;L&#34;, the tag closes and is fixed, and the pins travel to the other or shorter leg of the &#34;L&#34;-shaped gap, resulting in the opening of the taging end of the apparatus while its opposite ends, corresponding to the handle, remain closed. 
    
    
     BRIEF DESCRIPTION OF THE DRAWINGS 
     In order to better understand not only the construction of the apparatus of this invention, but also how same operates, following is an example of a possible modality of the apparatus, however understanding that this is simply an example and should in no manner serve as a limitation of the invention, the example corresponding to the enclosed drawings in which: 
     FIG. 1 is a top view of the apparatus in an open position, with the tag naturally still being divided in 2 sections or parts. 
     FIG. 2 is a side view of the apparatus in a closed position, consequently with both sections of the tag united. 
     FIG. 3 is a view of the apparatus similar to that of FIG. 2, but with the front end in an open position and the tag already closed. 
     FIG. 4 is a side view of the apparatus depicted in FIGS. 1-3. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The apparatus 1 shown in all the figures is of the pincer type, composed of two sections 2 and 3, each of which has a gap 4 in its central section, both gaps facing each other, while each section has, at one end, a handle 5. 
     Section 2 has a protrusion or projection 6 in its front end while section 3 has, in the same extremity, an indenture 7 in which one section of the tag P 1  is placed, while the other section P 2  of the tag is placed on protrusion 6. 
     Sections 2 and 3 are connected by two rectangular metal strips 8. The strips 8 are provided with the same configuration and are situated such that one of the strips overlies the other in a crosswise orientation. The strips are connected to one another at their center by means of a pin/center of rotation 9 on which a spring 10 is mounted, the ends 10a of which are fixed to pins 11 which serve as pivoting points for the ends 12 of each metal strip with regard to corresponding sections 2 and 3. In like manner, each metal strip has, at its opposite end, an &#34;L&#34;-shaped slot 13 which allows the connection of each metal strip 8 with a pin 14 which is fixedly mounted on on each section 2 and 3. 
     Upon closing the apparatus, with the corresponding fixing of the tag (see FIG. 2) each metal strip 8 is advanced along its corresponding longitudinal part of the slot 13. Each of the slots 13 has its angle 15 facing the corresponding pin 14. From this moment onward, and upon continued application of pressure on the handle, the metal strips 8 rotate and the pins 14 travel along towards the end of the shorter leg of the &#34;L&#34;-shaped slot 13, at which time the apparatus takes the position shown in FIG. 3, i.e., open position but with the handle end closed, which facilitates removal of the assembled tag from the tip of the apparatus. 
     The nature of the invention, as well as the manner in which to realize same, it should be noted that the modalities priorly explained and shown in the drawings are subject to modifications as long as the basic principles of the invention are not altered.
