Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, molding pellet 1 is fixed on base 5, base 5 is provided with axis hole 2, is provided with rotating shaft 3 in axis hole 2, and rotating shaft 3 is stretched out axis hole and formed limited post 4, limited post 4 and molding pellet 1 are located Kirschner wire 19 jointly, rotating shaft 3 fixes shifting block 6 by connector 31, and like this, molding pellet 1 and limited post 4 are by spacing for Kirschner wire 19, rotating shaft 3 is rotated, and shifting block 6 is stirred Kirschner wire 19 winding forming pellet 1 and is bent to form hook-shaped elbow.Not slippage in the process of Kirschner wire 19 is stirred in order to make shifting block 6, the position that can contact with Kirschner wire 19 on shifting block 6 arranges arcuate groove 61, arcuate groove 61 position is set as shown in Figure 4, make Kirschner wire 19 not with shifting block 6 slippage, the position that also can contact with Kirschner wire 19 on limited post 4 arranges annular groove 41, chute 41 position is set as shown in Figure 5 and Figure 6, make Kirschner wire 19 not with limited post 4 slippage; Certainly, although that Kirschner wire 19 can be made to be bent to form is hook-shaped for this situation, rotating shaft 3 is rotated more difficult.
In order to easy rotating shaft 3, need for rotating shaft 3 provides moment of torsion, and make rotating shaft 3 can rotate over 90 degree, for this reason, described base 5 is solidified as a whole with the binding clip side of pliers, the opposite side of binding clip by binding clip folding for rotating shaft 3 provides moment of torsion, but the maximum angle of binding clip folding is generally 45 degree, want to make rotating shaft 3 rotate over 90 degree, speeder (namely deceleration device) will be set between the main shaft 33 of pliers and rotating shaft 3, the sector gear of miter angle is such as fixed at main shaft 33, the sector gear of an angle of 90 degrees is fixed in rotating shaft 3, two sector gears engage completely, make main shaft 33 rotate 45 degree and drive rotating shaft 3 90-degree rotation, just can realize, certainly, sector gear also can be complete gear wheel, does not illustrate in this situation map.
As shown in Figure 7, at the main shaft 33 of pliers, guide rod 9 is set, it is exactly the opposite side (the same with the slide block of linkage) of aforementioned binding clip, guide rod 9 is arranged the slide block sample of slide block 10 and linkage, slide block 10 can slide along guide rod 9, rotating shaft 3 arranges crank 11, crank 11 is connected with slide block 10, form crank guide rod mechanism, now guide rod 9 length is greater than crank 11 length, just can limit the movable length of slide block 10, the rotational angle of crank 11 is made to be less than 180 degree, crank 11 and guide rod 9 synchronous hunting, just crank 11 pendulum angle is greater than guide rod 9 pendulum angle, the ratio of adjustment crank 11 and guide rod 9 length, the folding angle being applicable to binding clip just can realize crank-swinging 90 °, this embodiment does following change, and crank 11 arranges slide block 10, and slide block 10 slides along crank 11, and guide rod 9 is connected with slide block, because crank 11 is shorter, as shown in Figure 8, reaches the object of crank 11 and guide rod 9 synchronous hunting equally, another kind of situation, as shown in Figure 9, two slide blocks that can rotate each other 10 slide simultaneously on crank 11 and guide rod 9 simultaneously, also the object of crank 11 and guide rod 9 synchronous hunting can be reached, concrete just selecting on guide rod 9 arranges slide block I101, crank is arranged slide block II 102, be rotationally connected by axle 103 between slide block I101 and slide block II 102, as long as in fact link between crank 11 and guide rod 9, crank 11 and guide rod 9 synchronous hunting just can be made, the parts of interlock are not limited to slide block 10 etc., and above-mentioned interlock form, can reach with straight pin is same with the form of slot fit.
Described straight pin and slot fit link, and crank 11 is established monolayer hangers shape groove 112, single dome pin 92 established by guide rod 9, and single dome pin 92 mounts with monolayer hangers shape groove 112.So convenient installation.
The form of described straight pin and slot fit is: for establishing double-deck hangers shape groove 111 on crank 11, biconvex straight pin 91 established by guide rod 9, and biconvex straight pin 91 and double-deck hangers shape groove 111 mount.
Above-mentioned guide rod 9 is set to bending, exerts oneself large when being conducive to bending, state firmly little during reset.
As shown in Figure 5, between the handle 8 of pliers, back-moving spring 100 can be set.
During use, pliers handle 8 of holding with a firm grip, binding clip closes, guide rod 9 upwards rotates, and biconvex straight pin 91 drives double-deck hangers shape groove 111 upwards to rotate, as shown in Figure 10, thus driving shifting block 6 to rotate, shifting block 6 is stirred Kirschner wire 19 winding forming pellet 1 and is bent to form hook-shaped elbow, as shown in figure 11; Unclamp pliers handle 8, handle 8 opens by the back-moving spring 100 between handle 8, and binding clip opens, and guide rod 9 rotates, and biconvex straight pin 91 drives double-deck hangers shape groove 111 to rotate, thus drives shifting block 6 to reset.
The inner side of above-mentioned pliers two handle forms jaw 14.This jaw can be cut off longer Kirschner wire, easy to use, reaches multi-purpose object.
The handle arranged outside of the pliers be connected with base as above-mentioned in Figure 12 has measures bar 7, measures bar 7 and is movably arranged on handle, and handle is provided with and the groove 12 measured bar 7 and match, and handle is also provided with the pin hole 13 matched with jaw 14.The length measuring bar needs the length of dogleg section identical with Kirschner wire, when deployed, Kirschner wire is passed from pin hole, measure the skin that bar props up people, Kirschner wire length reserved is like this consistent with needing the length of dogleg section, and the part of stretching out pin hole is cut off by jaw.
The central axis of above-mentioned hangers shape groove 111 is straight line, as shown in figure 13.As shown in Figure 14, Figure 15, the central axis of hangers shape groove 111 can also be camber line or broken line.The hangers shape groove of different structure all can realize the object used, and in actual production process, can make the hangers shape groove of various structures as required.
Linking between described guide rod 9 and crank 11, is link between series winding two guide rods 9 and crank 11, is exactly in fact to add a power-assisted.
