Abstract
The invention relates to a hand-hold pincers with parallel jaws, which comprise a movable pincer, a fixed pincer and a fixed seat, wherein the movable pincer is pivoted with the fixed seat; a translational component is also arranged; a translational slide block and the fixed pincer are always parallel in the clamping process through the position matching of a guide rod, the translational slide block and the fixed pincer, which ensures that a clamped element can be stressed evenly in the clamping process and is not easy to slip; and a reset element is also arranged and can push back the translational slide block and the movable pincer together after the clamping action is completed so as to facilitate operation. The hand-hold pincers can also be used for clamping seals; the fixed pincer and the translational slide block can be provided with impression blocks with anti-counterfeiting marks so as to strengthen the anti-counterfeiting function of lead seals; simultaneously, the hand-hold pincers are also provided with a limit non-return component, so a lead seal cannot be taken out between the impression blocks even though the lead seal is not clamped halfway in the clamping process, and the hand-hold pincers clamp the lead seal to a preset thickness and then loosen the lead seal so as to improve the security of the lead seal.
Description
Technical field
The present invention relates to hand-operated tools, particularly a kind of hand-hold pincers with parallel jaw.
Background technology
In the prior art; Hand-hold pincers two jaws are to accomplish at a certain angle to clamp action, and the patent No. is that the Chinese patent of CN99103236.5 discloses a kind of safe pliers, and it is made up of two motion arms that two staggered pivots close; Be " X " shape; Two jaws are angled all the time closed fully to jaw in clamping process, and the chucking power of each point is uneven in jaw, and clamped is prone to produce skidding in clamping process.
Summary of the invention
The purpose of this invention is to provide a kind of hand-hold pincers with parallel jaw, it is simple in structure, two jaws remain parallel, clamped even, simple operation stressed in jaw in clamping process.
Above-mentioned technical purpose of the present invention is achieved through following technical scheme:
A kind of hand-hold pincers with parallel jaw; Comprise moving pincers, fixed pincers and moving pincers of connection and the fixed holder that clamps; Moving pincers are articulated on the holder, and said hand-hold pincers with parallel jaw also is provided with a translation assembly, and said translation assembly comprises translation slide block, the return unit that keeps the translation slide block to clamp the guide rod of translation relatively surely and the translation slide block is resetted; Said guide rod has on the said moving pincers to drive the drive division of translation slide block along the guide rod translation perpendicular to fixed pincers.
The present invention is provided with the translation slide block that can move along guide rod, and guide rod is perpendicular to fixed pincers, the position through guide rod, translation slide block, fixed pincers cooperate make the translation slide block with fixed clamp in clamping process, remain parallel; Guaranteed clamped can be stressed in clamping process evenly; Be difficult for producing skidding, be provided with return unit simultaneously again, after having accomplished the clamping action; Can the translation pincers be pushed back together with moving pincers, make things convenient for operation.
As preferably, the drive division on the said moving pincers is a protruding pulley, and this pulley articulates with moving pincers, and the pivoting point of pulley and moving pincers is about 10mm apart from the pivoting point of moving pincers and holder.Pulley is as the fulcrum that promotes the translation slide block movement; The translation slide block keeps in touch with pulley in by the process that pulley promotes and the part that is reset pushes back all the time, because pulley can rotate, has reduced the friction between pulley and the translation pincers; Make motion process more smooth-going, stable; Pulley is about 10mm with the moving pincers of pivoting point distance that move pincers and the pivoting point of holder simultaneously, compares with common hand-hold pincers, can produce bigger clamping torque.
As preferably, said return unit is a compression spring, and fixed pincers and translation slide block are provided with the blind hole of retainer spring.
As preferably, said fixed pincers and translation slide block are provided with dismountable die.When the present invention is applied to the clamping of lead sealing; Can on fixed pincers and translation slide block, be provided with the die of the false proof marking; Because fixed pincers remain parallel in clamping process with the translation slide block; There is not relative sliding phenomenon, the false proof marking on the die clearly is imprinted in the lead sealing, strengthened the antifalsification of lead sealing.
As preferably, said hand-hold pincers also comprises a spacing non-return assembly.When the present invention is applied to the clamping of lead sealing; In order to prevent that lead sealing from producing the phenomenon that does not clamp or deliberately do not clamp in the process of stepping up; The present invention also is provided with a spacing non-return assembly, even guaranteed lead sealing Halfway Stopping in clamping process, can not lead sealing be taken out between the die; Just can unclamp after must lead sealing being clamped to a preset thickness, increase the security of lead sealing.
As preferably; Said spacing non-return assembly comprises fixed mount, check pawl, back-moving spring and straight ratchet bar, and said fixed mount and holder are fixed, and check pawl and fixed mount articulate; Back-moving spring one end is connected with check pawl, the other end and decide clipper joint, and straight ratchet bar one end articulates with moving pincers.
As preferably, described fixed mount is provided with a spacing blend stop.
As preferably, the described straight ratchet bar back side leans against on the spacing blend stop.
As preferably, described straight ratchet bar is an incomplete tooth bar, and only continuous distributed is in the middle of tooth bar for ratchet, and all the other no toothed portions are the plane.As of the present invention further preferred, described straight ratchet bar does not have the vertical range of toothed portion plane to check pawl pin joint greater than the distance between check pawl pawl point to the check pawl pin joint.The setting of above-mentioned straight ratchet bar makes check pawl when having the tooth section to contact, and the motion of straight ratchet bar can only be unidirectional, can not retreat; And when getting into no toothed portion; Because the vertical range that straight ratchet bar does not have toothed portion plane to check pawl pin joint is greater than the distance between check pawl pawl point to the check pawl pin joint, just greater than the radius of gyration of check pawl, like straight ratchet bar counter motion at this moment; Ratchet can oppositely be pushed check pawl open, and straight ratchet bar could be released smoothly.
In sum, the present invention has following beneficial effect:
1, the present invention is provided with the translation slide block that can move along guide rod; Position cooperation through guide rod, translation slide block, fixed pincers makes the translation slide block in clamping process, remain parallel with fixed pincers; Guaranteed clamped can be stressed in clamping process evenly, be difficult for producing skidding.
2, the present invention is when being applied to the clamping of lead sealing; Can on fixed pincers and translation slide block, the die that has the false proof marking be installed; Because fixed pincers remain parallel in clamping process with the translation slide block; There is not relative sliding phenomenon, the false proof marking on the die clearly is imprinted in the lead sealing, strengthened the antifalsification of lead sealing.
3, the present invention also is provided with a spacing non-return assembly; When the present invention is applied to the clamping of lead sealing; Even guaranteed lead sealing Halfway Stopping in clamping process; Can not be with taking out between the lead sealing die, just can unclamp after must lead sealing being clamped to a preset thickness, increased the security of lead sealing.
4, the present invention is simple in structure, and clamping torque is big.
