Embodiment：

Below in conjunction with the accompanying drawings to the design explanation for example.

As shown in Figure 1, Figure 2, Figure 4 shows, the blade component for the reinforcing bar joint pliers that common tradition uses generally comprise blade 1, Lower blade 2, backplate 3, axis pin 4, blade are being made break-in operation and are often being occurred to slip the situation of cutting edge left outside reinforcing bar 10, such as scheming Shown in 4.For this reason, the design is provided with comprising on a set of auxiliary member device including intermediate plate 9 to former blade component, as Fig. 5, Fig. 6, Shown in Fig. 7, what the position of close line of symmetry was symmetrical above and below near the right edge on backplate 3 is machined with two card pin shaft holes 11 (shown in Fig. 5), card axis pin 8 of the outer end with the one strip card 9 of inner band of torsional spring 7 is all fixedly connected in hole, that is, is blocked Stretched to the left in the strip card 9 for being close to be flexibly connected a left and right directions device at backplate 3, the left end of card on piece axis pin 8 To the cutting edge head end of blade, the right end of card, which then stretches out to the right one section of the right edge of backplate and is fixed with one in right end, vertically to be stretched to The cylindric slide bar 6 of blade, the inner of slide bar 6 stretch into one be arranged on it is in blade, using the center of card pin shaft hole as the center of circle In one section of arc chute 5, card of two claws of torsional spring 7 another card on the side not near card right end close to line of symmetry In card hole not on the backplate on the outside of card, the elastic force of torsional spring make it that the left half of upper and lower card is tight centered on line of symmetry Lean on, meanwhile, corresponding teeth are all machined with the side abutted herein, as shown in Fig. 3, Fig. 5, Fig. 7；All make on front and rear backplate 3 Same card-type device often covers not only symmetrical above and below on blade component but also symmetrical installs four cards and its assisted parts Part.Concrete operations are in use, as shown in fig. 6, blade opens cutting edge（Angle between the right half of upper and lower blade is from large to small）, During this, manipulated by 5 outer end of sliding slot, slide bar 6 can also drive card 9 to overcome the elastic force of falling torsional spring 7 and around card Axis pin 8 turns an angle, i.e., the angle up and down between the right half of card also can be from large to small so that the teeth position of left half Magnifying and magnify with blade cutting edge, when cutting edge starts closure after the reinforcing bar to be blocked is placed between cutting edge up and down, is turned round The ratcheting firmly reinforcing bar of closure that the teeth part of card can be synchronous above and below the effect of the elastic torsion of spring 7 prevents its sliding, meanwhile, also It is not difficult to find that since device position, that is, card pin shaft hole 11 of card axis pin is in the right side position of the axis pin 4 on backplate 3, lead The slide bar 6 of card right end device is caused to determine to card axis pin 8 apart from outline less than the distance to the axis pin 4 on backplate, this point Determine during blade cutting edge opening and closing, the opening and closing for the card for making as above to organically combine with it not only also can Synchronous is servo-actuated, moreover, this servo-actuated speed can be slightly fast because of foregoing design feature, i.e., blade opening when card meeting Card can be closed prior to blade during the opening blade closure of greater angle, and such design feature and functional characteristics are for whole sword The work that piece component coordination coordinates is very necessary, and the mutually ratcheting effect for preventing reinforcing bar from skidding of upper and lower card can be more reliable, reinforcing bar 10 Reinforcing bar first can be vised by card clip tooth before being hobbed by the edge contacts of blade, then cutting edge just starts to contact above and below reinforcing bar up and down Face simultaneously starts application and blocks to hob power so that prevents to skid and block to hob successively to act on successively, rationally and efficiently, such as Fig. 6 institutes Show（Cutting edge is moved closer to until closure completes break-in operation and broken completely up and down during reinforcing bar is blocked by upper and lower cutting edge The card up and down of the reinforced bar support on mouthful both sides then can not be with the closure also synchronizing close of cutting edge, the difference between this card and blade The coordination of action that step can be accommodated certain amplitude of the slide bar 6 in groove by sliding slot 5 is come without retardance and movement punching occurs It is prominent）, and if the keying of card and the fully synchronized same angle of the keying of cutting edge, it is found that it can not prevent slip of bar, up to not To purpose of design.The blade component of such device can cause the break-in operation of reinforcing bar to be easier work efficiency higher, be this biography of joint pliers The useful improvement of system instrument.
