Second connecting rod, is connected with second handle by the 3rd bearing pin, and the first end of second connecting rod arranges the second elastomeric element, and the second elastomeric element is for the reset of second connecting rod, and the second end of first connecting rod is connected by the 4th bearing pin with the second end of second connecting rod;
When workpiece is placed between the first jaw and the second jaw, on first handle and second handle, apply the external force of opposite direction, make first handle and second handle move toward one another; Second handle rotates around the first bearing pin, makes the second jaw towards the first jaw translation, until the translation of workspace limits the second jaw; Second connecting rod drives second handle to move towards the second jaw, so that claw engages with the tooth of the first side wall; Continue to apply the power of opposite direction, second handle rotates around the first bearing pin, produces the clamping force of the power that is greater than described opposite direction and is delivered to the clamping face of the first jaw and the clamping face of described the second jaw.
The wrench of the jaw translation that the utility model provides, the first jaw is regular jaw, the second jaw is moving jaw, in the time that operator applies active force on first handle and second handle, the claw being connected with the first end of second handle moves along the second sidewall of the slotted hole of coupling part, drive the second jaw towards or deviate from the first jaw translation, form the wrench of jaw translation.
In the time there is no External Force Acting in the handle of the wrench of jaw translation, the power that the second elastomeric element produces on second connecting rod makes second connecting rod and first connecting rod in deployed condition, thereby makes the second jaw and the first jaw in a position that degree is maximum.
In the time having External Force Acting in the handle of the wrench of jaw translation, the second elastomeric element produces strain, the second jaw is towards the first jaw translation, Zhang Du between the second jaw and the first jaw reduces, until contact with workpiece, when external force is not done the used time, under the effect of the power producing in the second elastomeric element strain, second connecting rod and first connecting rod launch, and the second jaw deviates from the first jaw translation, make the second jaw and the first jaw in a maximum position of degree.
The wrench of the jaw translation that the utility model provides, jaw can open automatically, and needn't manually jaw be opened in advance, makes the wrench of this jaw translation can carry out easily with one hand the operation of holding workpiece.
In the time having External Force Acting in the handle of the wrench of jaw translation, the second elastomeric element produces strain, the second jaw is towards the first jaw translation, Zhang Du between the second jaw and the first jaw reduces, until contact with workpiece, now continue to apply external force, the second jaw is subject to the power that deviates from the first jaw that workpiece applies, and this power passes to the cam of second handle by the recess of the second jaw, the resilient force of the first elastomeric element is in the first end of first connecting rod, direction is to deviate from the direction of jaw along first handle, this elastic force produces the active force of opposite direction at the second end of first connecting rod, this active force acts on second connecting rod by the 4th bearing pin, and act on second handle by the 3rd bearing pin, the power that second handle applies at the workpiece that acts on cam, act on the elastic force of the first elastomeric element of the 3rd bearing pin, act under the external force of handle and the acting in conjunction of the elastic force of the second elastomeric element to second handle, generation is moved towards the first side wall of the slotted hole of coupling part, claw is engaged with the tooth of the first side wall, now the second jaw and coupling part can not relative slidings, continue to apply the power of opposite direction, second handle rotates around the first bearing pin, cam rotation, the 4th bearing pin moves towards the direction that deviates from attaching parts, the distance that the arm of force of active force is External Force Acting in the application point of the handle of the wrench of jaw translation to the first bearing pin, resistance arm is the distance of cam edge to the first bearing pin, thereby second handle is laborsaving lever, can produce larger chucking power, be delivered to the clamping face of the first jaw and the second jaw.
The wrench of the jaw translation that the utility model provides, adopts two-stage transmission, and first order transmission is for jaw translation, and second level transmission is for providing larger chucking power; In the time that claw does not engage with the tooth of the first side wall, be first order transmission, be second level transmission in the time that claw engages with the tooth of the first side wall, has higher effect.
Adopt two-stage transmission, in the time that external force no longer acts on the handle of wrench of jaw translation, first, under the effect of the elastic force of the first elastomeric element, first connecting rod rotates, the 4th bearing pin is moved towards the direction of attaching parts, shed the large chucking power between the first jaw and the second jaw; Now the tooth of claw and the first side wall is thrown off, and can not cause structural failure, makes the longer service life of the wrench of jaw translation.

The wrench of the jaw translation in the present embodiment adopts Forging Technology to make.
The first elastomeric element is extension spring.
The second elastomeric element is extension spring.
In the time there is no External Force Acting in the handle of the wrench of jaw translation, the pulling force that extension spring produces on second connecting rod 62 make second connecting rod 62 with first connecting rod 61 in deployed condition, thereby make the second jaw and the first jaw in spending a maximum position.
In the time having External Force Acting in the handle of the wrench of jaw translation, extension spring stretches, the second jaw 4 is towards the first jaw 1 translation, Zhang Du between the second jaw 4 and the first jaw 1 reduces, until contact with workpiece, when external force is not done the used time, under the effect of the pulling force of extension spring, second connecting rod 62 launches with first connecting rod 61, the second jaw 4, to the direction translation that deviates from the first jaw 1, makes the second jaw 4 and the first jaw 1 in a maximum position of degree.
The wrench of the jaw translation in the present embodiment, jaw can open automatically, and needn't manually jaw be opened in advance, makes the wrench of this jaw translation can carry out easily with one hand the operation of holding workpiece.
First connecting rod 61, for folding shape, prevents that the first connecting rod anglec of rotation is excessive, and the 4th bearing pin 74 is crossed on the line of the second bearing pin 72 and the 3rd bearing pin 73, causes linkage stuck.
The wrench of the jaw translation that the utility model provides, jaw translation is applicable to clamp various workpieces; Adopt two-stage transmission, larger chucking power can be provided, there is higher effect, in the time that external force no longer acts on the handle of wrench of jaw translation, first under the effect of the elastic force of the first elastomeric element, first connecting rod rotates, and the 4th bearing pin is moved towards the direction of attaching parts, sheds the large chucking power between the first jaw and the second jaw; Now the tooth of claw and the first side wall is thrown off, and can not cause structural failure, makes the longer service life of the wrench of jaw translation; Also comprise locking mechanism, for keeping the state of clamping, operating personnel's hand can be freed, complete other operations under clamp position.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
