         [0002]     The present invention is related to a pair of press-connecting pliers for coaxial pins of multiple specifications, and especially to a pair of press-connecting pliers for connecting pins and wires of at least two specifications by diversion and position changing of a press-connecting die block to be opposite to a press-connecting head, thereby the pliers can do press connecting of pins and wires of various specifications.  
         [0003]     2. Description of the Prior Art  
         [0004]     Coaxial wires with pins are divided into several classes in pursuance of various functions as well as their modes of using; e.g., wires for sound channels, for broadband networks and for cable television sets using pins with different specifications and sizes; thereby when in connecting pins with wires, generally, different press-connecting pliers are required for wires and pins with different specifications.  
         [0005]     While in using a pair of press-connecting pliers, it is practiced mainly in that two handles are provided thereon with a press-connecting die block of a specification, and a corresponding press-connecting head inserts a wire onto the tailing ends of a pin and then put them on the press-connecting die block, after that, the handles are pressed to get close to each other to render the press-connecting head to move toward the wire and the pin on the press-connecting die block, this can force the pin to wrinkle to clamp tight the wire, and shaping of the wire and the pin can be completed.  
         [0006]     The above stated conventional press-connecting pliers must be changed in pursuance of wires and pins with different specifications, thereby an effect of wrinkling and shaping of the wires and pins with different specifications can be obtained; this not only makes quite inconvenience in carrying, but also makes inconvenience in use.  
         [0007]     Therefore, it is the gist of the present invention to provide a pair of press-connecting pliers for press connecting pins and wires of various specifications.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0022]     The press-connecting pliers for coaxial pins of multiple specifications of the present invention, as are shown in  FIGS. 1-4 , mainly comprises a first handle  10 , a second handle  20 , a press-connecting head  30  and a press-connecting die block  40 . Wherein:  
         [0023]     The first handle  10  has two fixing sheets  11  on its upper end, and has a holding sleeve  12  on its lower end, the fixing sheets  11  are provided each with two slide slots  13  in correspondence with each other, and the two fixing sheets  11  are provided therebetween with a fixing block  14  locked with bolts. The fixing block  14  has thereon a screw-connecting portion  15  and a positioning portion  16  which includes a positioning member  17  and a restoring spring  18 .  
         [0024]     The second handle  20  has two fixing sheets  21  on its upper end, and has a holding sleeve  22  on its lower end, the two fixing sheets  21  are provided therebetween with a linkage portion  23  which is provided with a slide block  24  in alignment with the slide slots  13  respectively, so that press closing of the first handle  10  to the second handle  20  can render sliding of the slide block  24  of the linkage portion  23  in the slide slots  13 , and push the linkage portion  23  upwardly. The linkage portion  23  further is provided with a screw-connecting hole  25  for mounting by screw connecting of the press-connecting head  30 . And a link  50  is provided between the first handle  10  with the second handle  20 .  
         [0025]     The press-connecting head  30  is provided on the second handle  20 , and has a thread portion  31  on its bottom in opposition to the screw-connecting hole  25  of the linkage portion  23 , in order that the press-connecting head  30  can be mounted by screw connecting on the linkage portion  23 , and can be moved by the linkage portion  23  for displacement. The thread portion  31  is provided with an adjusting screw  32  which can render the press-connecting head  30  to make height adjustment on the linkage portion  23 .  
         [0026]     The press-connecting head  30  has in the interior of its upper end a press-connecting recess  33  with a plurality of steps; the press-connecting recess  33  is designed for pins of various specifications. The press-connecting head  30  further is provided with a screw hole  34  centrally on its upper end, this allows mounting of a positioning bolt  35  thereon. The positioning bolt  35  has a through hole  36  on its upper end in order that central core wires of cable television can be extended into the through hole  36 .  
         [0027]     The press-connecting die block  40  at least has two set of press-connecting sections  41  for placing therein two set of wires and pins of different specifications (there are three sets in the embodiment shown). And the press-connecting die block  40  has a hole  42  to slip over the screw-connecting portion  15  of the fixing block  14 , it is locked on the screw-connecting portion  15  by extending a screw-connecting bolt  43  into the hole  42 ; thereby the press-connecting die block  40  can make diversion to change the positions of the press-connecting sections  41  by rotating on the first handle  10  about the screw-connecting portion  15 , so that one of the press-connecting sections  41  is aligned with the press-connecting head  30 . And the press-connecting die block  40  is provided with at least a positioning groove  44  for engagement therein of the positioning member  17  of the positioning portion  16 .  
         [0028]     Thereby, the press-connecting die block  40  can divert on the first handle  10 ; with the positioning portion  16  formed between the press-connecting die block  40  and the fixing block  14 , and the positioning portion  16  is composed of the positioning member  17  and the restoring spring  18 , hence when the press-connecting die block  40  diverts, the positioning member  17  can compress the restoring spring  18 . When one of the press-connecting sections  41  is rotated to its proper position to be aligned with the press-connecting head  30 , the positioning groove  44  is also in alignment with the positioning member  17 , so that the positioning member  17  is acted by an elastic restoring force of the restoring spring  18  to move toward the positioning groove  44  and is engaged in the positioning groove  44 ; in this way, diversion and positioning of the press-connecting die block  40  to be aligned with the press-connecting head  30  can be achieved. At this time, by press closing of the first handle  10  to the second handle  20 , the press-connecting head  30  can be moved by the linkage portion  23  toward the press-connecting die block  40 .  
         [0029]     Referring simultaneously to  FIGS. 1, 5  and  6 , the press-connecting die block  40  at least has two set of press-connecting sections  41 , hence by diversion of the press-connecting die block  40 , one of the press-connecting sections  41  is aligned with the press-connecting head  30 , so that press connecting on two set of wires and pins can be effected. And one can choose whether a positioning bolt  35  shall be added in pursuance of the requirement of the wires and pins, thereby a pair of pliers suitable for press connecting of pins and wires of multiple specifications is provided.  
         [0030]     Additionally, the first handle  10  can be added with a safety sheath  60  at the lateral external side of the press-connecting die block  40  and the fixing sheets  11  to avoid exposure of the fixing sheets  11 , the linkage portion  23  and the press-connecting die block  40 . The safety sheath  60  has a notch  61  corresponding by position to either of the press-connecting sections  41 , so that when the press-connecting die block  40  diverts, such as is shown in  FIG. 2 , it can move one of the press-connecting sections  41  at either side thereof into the notch  61  for the purpose of protection.  
         [0031]     Referring to  FIGS. 7-9  which are schematic perspective views showing the press-connecting head  30 , wires  71 - 73  and pins  81 - 83  of the present invention in press connecting the wires  71 - 73  with the pins  81 - 83 . When the press-connecting head  30  does press connecting on the wire  71  for sound channel and the pin  81  of the RCA type meeting the specification of the wire  71 , on the wire  72  for broadband networks and the pin  82  of the BNC type meeting the specification of the wire  72  as well as on the wire  73  for cable television sets and the pin  83  of the F type meeting the specification of the wire  73 , one can choose whether the positioning bolt  35  shall be added in pursuance of the features of the pins for the different wires.  
         [0032]     One thing is worth mentioning, as shown in all the drawings attached, the press-connecting pliers for coaxial pins of multiple specifications of the present invention is provided with the divertible press-connecting die block  40 , the press-connecting die block  40  has at least the two set of press-connecting sections  41 , with using the press-connecting head  30  and the positioning bolt  35 , the press-connecting pliers can do press connecting of pins and wires of various specifications.  
         [0033]     In the meantime, the press-connecting die block  40  can allow changing of itself by the provision for screw connecting of the screw-connecting bolt  43  with the screw-connecting portion  15  of the fixing block  14 , thereby the scope of application of the press-connecting pliers can be wider, and thereby a pair of press-connecting pliers can be used to align and press connect one press-connecting die block  40  chosen from various press-connecting die blocks with the press-connecting head  30  for various wires and pins.
