Description

Duplex connects lazy tongs

Technical field the utility model relates to manual Hardware pliers, and it is that a kind of duplex that the two pincers pincers of binding clip and handle axle connects connects lazy tongs.

The existing traditional Hardware pliers of background technology, its pincers handle is all shorter, adopt a pincers axle to connect binding clip and pincers handle, be used to turn or cut off object, thing as screw or steel wire and so on, but when operation, binding clip and the big or small same ratio of the pincers open angle of handle (scope), on function of use, just placed restrictions on, extracted or the shearing object, just can't be reached the purpose of achieving one's goal as interval operation dark in the degree of depth and that width is narrower, also have a class long handle pliers or a clip, because the mechanical force of clamp is less, can not be applied in some industrial trade, as automobile, vessel some processing and manufacturing neck or middle uses.

Summary of the invention is in some manufacture fields, for the mechanical connection that solves some special dark narrow intervals or occasion or the cutting of metal species or non-metal kind object, the utility model provides a kind of and can work within dark narrow interval range, and has the duplex of good mechanical performance to connect lazy tongs.

Duplex connects the structure technology scheme of lazy tongs, following description will be arranged: this utility model structure mainly includes binding clip, binding clip pincers axle, the pincers handle, pincers handle pincers axle, binding clip has binding clip left side sheet and the right sheet of binding clip, the pincers handle has pincers handle left side sheet and the right sheet of pincers handle, a binding clip left side, right sheet afterbody is processed with shaft-jointed hole, a binding clip left side, right sheet is connected by binding clip pincers axle, a pincers handle left side, right sheet head is processed with shaft-jointed hole, a pincers handle left side, right sheet is connected by pincers handle pincers axle, and binding clip connects binding clip left side sheet shaft-jointed hole and the right sheet shaft-jointed hole of pincers handle with the pincers handle respectively by coupling spindle, right sheet shaft-jointed hole of binding clip and pincers handle left side sheet shaft-jointed hole.Pincers handle rear Design of length be more than or equal to segment length before 2 times of pincers handles, clamps handle leading portion Design of length and be 2 times more than or equal to the binding clip rear, and binding clip leading portion Design of length is 2 times more than or equal to binding clip rear length.

The utility model design adopts pincers handle pincers axle to connect left and right of pincers handle, binding clip pincers axle connects left and right of binding clip, the duplex structure that connects binding clip and pincers handle again by coupling spindle, it can be applied in narrower dark interval, the function of extracting or shearing or tighten object, overcome the general tool pincers and open near equal angle, placed restrictions on the limitation of above-mentioned application because of binding clip and pincers handle.Another characteristics are the length that pincers handle length is longer than the binding clip rear, can make binding clip mechanical performance advantage more, operate light.

1-binding clip left side sheet, the right sheet of 2-binding clip, 3-binding clip pincers axle, the right sheet shaft-jointed hole of 4-binding clip, 5-binding clip left side sheet shaft-jointed hole, 6-pincers handle left side sheet shaft-jointed hole, the right sheet shaft-jointed hole of 7-pincers handle, 8-pincers handle pincers axle, 9-pincers handle left side sheet, the right sheet of 10-pincers handle, 11-coupling spindle, 12-screw, 13-deep hole.

The specific embodiment is is further recorded and narrated summary of the invention with reference to the accompanying drawings again: binding clip left side sheet 1 of the present utility model and the right sheet 2 of binding clip constitute binding clip by 3 movable connections of binding clip pincers axle, its binding clip pincers axle 3 front ends are binding clip leading portions, binding clip pincers axle 3 rear end parts are binding clip rears, pincers handle left side sheet 9 and the right sheet 10 of pincers handle constitute the pincers handle by 8 movable connections of pincers handle pincers axle, its pincers handle pincers axle 8 fore-ends are pincers handle leading portions, and pincers handle pincers axle 8 rear end parts are pincers handle rears.The shaft-jointed hole 4 of binding clip and left sheet 1 of each self-corresponding binding clip of pincers handle and the right sheet 2 of binding clip and 5 is with pincers handle left side sheet shaft-jointed hole 7 and clamp the right sheet shaft-jointed hole 6 of handle through 11 movable connections of coupling spindle.Consult Fig. 1 a and Fig. 1 b.The caliper length of this pincers is processed into the application need that the 12-60 centimetre can be fit to various common mechanism deep hole processing places, and along with the length of pincers handle length greater than binding clip, the mechanical force of corresponding binding clip is greater than holding pincers handle active force, as shown in Figure 6, pliers enters the deep hole 13 of two connection objects, seize screw 12 on both sides by the arms and tighten or unclamp, thereby make two connected objects connect jail or separately.

Structure of the present utility model can be processed into the duplex with various mechanism performance binding clips and connect lazy tongs; Read shown in Fig. 1 a is duplex spreading handle nipper plier, nipper plier head and pincers handle by coupling spindle 11 flexibly connect left and right shaft-jointed holes 4 of binding clip and 5 with clamp left and right shaft-jointed hole 6 of handle and 7, it can operation in deep hole gripping object or fastening connection piece, as the connection of securing member, it can gripping be in the object in the dark cave.

And for example binding clip is the duplex spreading handle cutting pliers of cutting pliers, steel wire binding clip and pincers handle by coupling spindle 11 flexibly connect left and right shaft-jointed holes 4 of binding clip and 5 with clamp left and right shaft-jointed hole 6 of handle and 7, consult Fig. 3, it must tighten soft, the hard object in connector or the shearing deep hole.

Be that binding clip is the duplex spreading handle diagonal cutting nippers of diagonal cutting nippers again, diagonal cutting nippers head and pincers handle by coupling spindle 11 flexibly connect left and right shaft-jointed holes 4 of binding clip and 5 with clamp left and right shaft-jointed hole 6 of handle and 7, consult Fig. 4, be used for shearing the object of moulding pipe or steel wire class that is in the object deep hole.

Be that binding clip is the duplex spreading handle round pliers of round pliers in addition, round pliers head and pincers handle by coupling spindle 11 flexibly connect left and right shaft-jointed holes 4 of binding clip and 5 with clamp left and right shaft-jointed hole 6 of handle and 7, consult Fig. 5, it can take out in the deep hole various difform objects and connect.
