Press Plier 1 also comprises a torque spring 50, and torque spring 50 is arranged on pressure handle 30 and 13 articulated section, articulated section.

Please refer to shown in Fig. 3 and Fig. 4, be respectively use reference diagram of the present utility model () and use reference diagram (two), when wish combines conductor wire 8 and connector 9, at first can first conductor wire 8 be penetrated in connector 9, again connector 9 is inserted in the crimping mouth 142 of start section 14, afterwards pressure handle 30 is imposed to a directed force F 1, pressure handle 30 is moved towards the direction of base 10, to drive connecting rod 21 and guide pillar 211, along articulated section, 13 bullport 131 moves toward the direction of main paragraphs 12, the direction that makes connecting rod 21 promote sliding part 22 past start sections 14 moves, and then the pressure contact portion 222 of sliding part 22 is moved in crimping mouth 142, allow 223 pairs of connectors 9 of crimping tooth of pressure contact portion 222 impose a pressure, and connector 9 and conductor wire 8 pressings are fixed into to one.

Wherein because articulated section 13 and the articulated section of pressure handle 30 are equipped with a torque spring 50, therefore after by connector 9, with conductor wire 8 pressings, fixedly the all-in-one-piece program completes, one tension force that just can provide by torque spring 50, to drive pressure handle 30, toward the direction away from base 10, move, making pressure handle 30 drive connecting rod moves toward the direction away from start section 14, so that sliding part 22 is pulled toward the direction away from crimping mouth 142, and allow the pressure contact portion 222 of sliding part 22 shift out crimping mouth 142, to make the fixing program of connector 9 next time and the pressing of conductor wire 8.

Wherein between each ratchet 41, be formed with respectively an embedded slot 411, when connecting rod 21 promotion sliding parts 22 move toward crimping mouth 142, its blocking block 421 that supports master unit 42 can embed in corresponding embedded slot 411 along the opposite direction moved with sliding part 22, with time elastomer 43, can provide to master unit 42 1 pulling force, and make the ratchet 41 of blocking block 421 contrapositions in the one or both sides of embedded slot 411 produce a pressure, blocking block 421 and position are fixed at the mutual stopper of ratchet 41 of the one or both sides of embedded slot 411, thereby avoid pressure handle 30 to move toward the direction away from base 10 because of the tension force effect of torque spring 50, can save whereby the user and pressure handle 30 be moved to the size of executed active force towards base 10, and reach outside the effect of labour-saving, in addition, the function that also there is location, moreover, when wanting to make pressure handle 30 courts retract original position away from the direction of base 10 by the tension force of torque spring 50, can be by the pad 422 that compresses master unit 42 and be exposed to base 10 outsides, pad 422 is driven and support master unit 42 rotations, so that blocking block 421 shifts out in embedded slot 411, thereby make pressure handle 30 can retract smoothly original position.

When the pressure contact portion 222 of sliding part 22 moves into crimping mouth 142 when interior, can promote retaining pin 44 and be exposed to sincere section 441 ends of gear of base 10 outsides, and the direction that promotes retaining pin 44 past extensions 442 moves, making to keep off sincere section 441 can support sincere with the block 225 of sliding part 22 mutually, with when connector 9 and conductor wire 8 are carried out to the pressing program, prevent that the reaction force that 9 pairs of pressure contact portions 222 of connector produce from pushing away crimping mouth 142 by the pressure contact portion of sliding part 22 222, cause the fixing procedure failure of connector 9 and conductor wire 8 pressings, therefore reach the effect to sliding part 22 and pressure contact portion 222 retainings, and also can save the directed force F 1 that the user puts on pressure handle 30, in addition, after the pressing fixed routine of connector 9 and conductor wire 9 completes, can promote retaining pin 44 and be exposed to 442 ends, extension of base 10 outsides, to promote retaining pin 44, toward the direction of keeping off sincere section 441, move, make to keep off sincere section 441 and move apart block 223, and make pressure handle 30 retract smoothly original position by the tension force of torque spring 50, be returned to original position and drive crimping member 20.

In addition, can slip by the pilot pin 224 of sliding part 22 guide groove 141 of start section 14, making it sliding part 22 can move along guide groove 141 when mobile, can make whereby the movement of sliding part 22 for moving horizontally, guarantee that 222 pairs of connectors 9 of pressure contact portion and conductor wire 8 impose comparatively average compression and reach, and then improve the pressing effect of 222 pairs of connectors 9 of pressure contact portion and conductor wire 8.

Moreover, conductor wire 8 can be positioned between the first cutoff tool 121 and the second cutoff tool 31, move with the direction towards base 10 by pressure handle 30 is imposed to directed force F 1, move toward the direction of the first cutoff tools 121 and drive the second cutoff tool 31, reach the function of cutting off conductor wire 8; In addition, as wish divests the coating layer of conductor wire 8, the wire rod that makes it conductor wire 8 is out exposed, conductor wire 8 can be positioned in short slot 122 or recessed groove 123, after pressure handle 30 is imposed to directed force F 1, the direction that drives the second cutoff tool 31 past bases 10 moves, and with the coating layer of excision conductor wire 8, and then reaches the effect that divests conductor wire 8 coating layers.

The above embodiment is only the preferred embodiment for absolutely proving that the utility model is lifted, and protection range of the present utility model is not limited to this.Being equal to that those skilled in the art do on the utility model basis substitutes or conversion, all within protection range of the present utility model.Protection range of the present utility model is as the criterion with claims.
