The specific embodiment
Below in conjunction with accompanying drawing, the utility model water pump pliers is described in further detail.
As Fig. 1, shown in Figure 2, a kind of water pump pliers, the left caliper 1 and the right caliper body 2 that comprise a pair of mutual cross-articulation, left caliper 1 is made up of right binding clip 3 and left side pincers handle 4, right caliper body 2 is made up of left binding clip 5 and right pincers handle 6, offer bar hole 7 between the right binding clip 3 of described left caliper 1 and the left side pincers handle 4, one side of bar hole 7 is provided with teeth 8, one side of right caliper body 2 fixedly installs cover plate 9, left caliper 1 is located between right caliper body 2 and the cover plate 9, the two ends of cover plate 9 are fixedly installed on the right caliper body 2 by rivet 10, when actual production, can directly cover plate 9 be welded on the right caliper body 2, offer first hinge hole 11 between left side binding clip 5 and the right pincers handle 6, cover plate 9 is provided with second hinge hole 12 that matches with first hinge hole 11, one end of bearing pin 13 is positioned at first hinge hole 11, the other end is positioned at second hinge hole 12, wherein portion is positioned at bar hole 7, the middle part of bearing pin 13 is arranged with the ratchet 14 that cooperates with teeth 8, ratchet 14 is provided with first aperture 15, one side of second hinge hole 12 is provided with torsion spring hole 16, torsion spring 17 is embedded in the torsion spring hole 16, this set method can reduce the thickness of whole water pump pliers, and the two ends of described bearing pin 13 flush with the outer side edges of cover plate 9 and right caliper body 2 respectively, further reduce the thickness of whole water pump pliers, made water pump pliers in narrow space, to work.One end of torsion spring 17 is arranged in first aperture 15, and the other end is arranged in second aperture 18 of second hinge hole, 12 1 sides.
Operation principle of the present utility model is: water pump pliers is when normal the use, the ratchet 19 of ratchet 14 heads is in the state that is meshed with the teeth 8 of bar hole 7 one sides always under the effect of torsion spring 17, at this moment, right binding clip 3 and left binding clip 5 also are in open configuration always, workpiece is placed between right binding clip 3 and the left binding clip 5, then left side pincers handle 4 and right pincers handle 6 are applied inside active force, right binding clip 3 and left binding clip 5 clamp closing up of handle 6 along with the left side pincers handle 4 and the right side and close up, and promptly play the purpose of clamping work pieces.In this process, because right side pincers handle 6 rotates around bearing pin 13, make torsion spring 17 produce certain deformation, after removing the active force that left side pincers handle 4 and right pincers handle 6 are applied, do to reset rotation under the elastic force that right pincers handle 6 can produce when torsion spring 17 recovers deformation, promptly left side pincers handle 4 and right pincers handle 6 open automatically.
If adjust right binding clip 3 and left binding clip 5 openings of sizes when initial, as long as left side pincers handle 4 and right pincers handle 6 are applied outside power, making right pincers handle 6 drive torsion spring 17 rotates around bearing pin 13, torsion spring 17 drives ratchet 14 and rotates, when the teeth 8 out-of-gear states of the ratchet 19 of ratchet 14 heads and bar hole 7 one sides, at this moment, right caliper body 2 can slide arbitrarily in the bar hole 7 of left caliper 1 along with bearing pin 13, when being adjusted to desired location, left side pincers handle 4 and right pincers handle 6 are applied inside active force, making right pincers handle 6 drive torsion spring 17 rotates around bearing pin 13, torsion spring 17 drives ratchet 14 and rotates until the ratchet 19 of ratchet 14 heads and teeth 8 engagements of bar hole 7 one sides, and this water pump pliers can normally use again afterwards.
