Specific embodiment
This utility model is described further below in conjunction with Figure of description.
As Figure 1-3, locking pliers of the present utility model, including the first handle 01, the second handle 02, the first binding clip 03, second
Binding clip 04, push rod 05, the first binding clip 03 are fixed on the first handle 01, and the second binding clip 04 is connected with the first handle 01 by the first bearing pin 11
Connect, between the first binding clip 03 and the second binding clip 04, form jaw, the second binding clip 04 is rotated around the first bearing pin 11 can be with the first binding clip
03 is matched for clamping tightly workpiece or unclamps workpiece, and the second handle 02 is connected with the second binding clip 04 by the second bearing pin 41, on the first handle 01
Axially position the screw rod 06 that can be rotated is provided with around the axis of itself, and the rear end of screw rod 06 has the rotation behaviour for stretching out the first handle 01
Make portion 61 for rotating screw rod, on screw rod 06, be connected with the nut 07 moved axially with the rotation of screw rod, 05 rear end of push rod leads to
Cross the 3rd bearing pin 71 to be connected with nut 07, the front end of push rod 05 is connected with the second handle 02 by the 4th bearing pin 21, the 4th bearing pin 21
It is located between the second bearing pin 41 and the 3rd bearing pin 71, when closing up the first handle 01, the second handle 02, promotes the 4th bearing pin 21 to move to the
The side near the first bearing pin 11 of 71 line n of two bearing pins 41 and the 3rd bearing pin is in order to clamping workpiece（It is shown in Fig. 1-2 and clamps
State）, when separating the first handle 01, the second handle 02, promote the 4th bearing pin 21 to move to 71 line n of the second bearing pin 41 and the 3rd bearing pin
The side away from the first bearing pin unclamping workpiece.When foundation workpiece needs the size of adjusting jaw, by rotating operation portion 61
The position of 06 adjusting nut 07 of screw rod is rotated adjusting position of second binding clip 04 relative to the first binding clip 01, as shown in Figure 1-2,
When nut 07 is moved up, force the second binding clip 04 around the first bearing pin 11 rotationally clockwise near the first binding clip 03, from
And reduce jaw；When nut 07 is moved down, make the second binding clip 04 around 11 rotate in an anti-clockwise direction of the first bearing pin away from first
Binding clip 03, so that increase jaw.During adjusting nut position, screw rod will not stretch, so as to make the first handle keep original
Length.
For the ease of assembling, the first handle 01 is provided with two bearing portions 12, it is illustrated that bearing portion be to open on metal sheet
If for the breach for assembling screw rod, it is axially fixed that screw rod 06 is realized by the breach assembling of cervical region 62 thereon and two bearing portions 12
Position simultaneously can be rotated around the axis of itself.The metal sheet can be replaced with the rolling bearing of standard completely when being embodied as.
Especially, the first handle 01 by sheet metal bending form, so as to have two side walls 13, two side walls 13 it
Between formed groove 14.Two bearing portions 12 are located in the groove 14 of the first handle 01 and are fixed with side wall 13.Nut 07 is located at the first handle 01
Two side 13 between, two side 13 limit nut 07 rotate, to nut be oriented to.
In order to aid in unclamping the workpiece being clamped, spring 42, spring 42 between the first handle 01 and the second binding clip 04, is connected with

In the groove of handle 01, the other end of spring 42 is connected on the second binding clip 04 portion being located between the first bearing pin 11, the second bearing pin 41
Position.When the first handle 01, the second handle 02 is separated, the elastic force of spring 42 promotes the second binding clip 04 around 11 counter clockwise direction of the first bearing pin
Rotate and unclamp workpiece, especially in naturalness, the elastic force of spring 42 can promote the second binding clip 04 relative to the first binding clip
03 open-shaped state, to clamp workpiece.
Operate to unclamp, one the 3rd handle 08, the 3rd handle are connected by the 5th bearing pin 22 on the second handle 02
Extend the rear end of the second handle 02 so as to while gripping the 3rd handle 08, the first handle 01, the middle part of the 3rd handle 08 is provided with 08 rear end
The supporting part 81 of corresponding nut 07, when closing up the first handle 01, three handles 08, supporting part 81 is made on nut 07 as fulcrum support
5th the second handle 02 of bearing pin 22 pairs force promotes the second handle 02 to separate with the first handle 01.When workpiece is stepped up, if workpiece to be unclamped,
Then gripping the 3rd handle 08, the first handle 01 simultaneously makes the 3rd handle 08, the first handle 01 close up, then the supporting part 81 of the 3rd handle 08 is used as to prop up
Point is supported on nut 07 and makes 22 pairs of the second handles 02 of the 5th bearing pin exert a force, and promotes the second handle 02 to separate with the first handle 01.Design is produced
During product, force arm during by designing position of the supporting part 81 on the 3rd handle 08 to determine the 3rd handle as lever is more than resistance
Arm, you can reach labour-saving effect.
Reset for the ease of the 3rd handle, effect between the second handle 02 and the 3rd handle 08 has spring 82,82 elastic force of spring to promote
3rd handle 08 is leaned against on the second handle 02.Spring 82 is the torque spring being enclosed within the 5th bearing pin 22, and the two ends of torque spring are distinguished
It is supported on the 3rd handle 08, the second handle 02.
