Abstract

The utility model discloses a wire binding tool, comprising a screw rod with a drag hook fixed at the front end, a slotted nut sleeved at the front part of the screw rod, a spring sleeve outside the screw rod and between the back end of the slotted nut and a position limitation end at the back of the screw rod, wherein the slotted nut comprises a front convex ring, a middle nut with external screw and a clipping ring with slots and the tube with internal screw at the front end is sleeved outside the spring and in screw connection with the nut and an iron ball is arranged in the slot of the clipping ring. The wire binding tool widely used in civil engineering has features of reasonable structure, convenient use and greatly increased wire-binding work efficiency.

Description

A kind of bundle silk instrument

Technical field

The utility model relates to a kind of hardware ﹠ tools that is applied in the civil engineering, particularly a kind of bundle silk instrument.

Background technology

At present, the common on the market colligation instrument that is applied in the civil engineering comprises Metallic rod handle of making and the drag hook that is arranged at handle end.During use, drag hook is tangled the bundle silk, thereby hand-held handle is tightened the colligation point through repeatedly changing the hand-screw commentaries on classics.Because the work of bundle silk is the master operation in the civil engineering, civil engineering reinforcing bar binding point at least several ten thousand, up to a million at most, the number of colligation point is big to make that this work is very consuming time, consumption power, it is inhomogeneous, irregular to prick the steel wire that comes out, only by above-mentioned instrument prick the silk the words operating efficiency extremely low, influenced programming greatly.Afterwards, people have invented a kind of bundle silk instrument, thereby this bundle silk instrument make in the time of can be by the pulling handle drag hook automatically rotation the colligation point is tightened, but owing to pulling back drag hook can reset in opposite spin, the colligation point that causes just having tightened unclamps, at this moment, drag hook after waiting it to reset, the steel wire taking-up need be spurred the colligation point once more, by the colligation point being tightened after the repeated multiple times, this instrument uses still very effort, than between its operating efficiency of bundle silk instrument do not have great raising, at above-mentioned shortcoming, be necessary to make improvements.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, easy to use, can improve a kind of bundles instrument of pricking the silk operating efficiency.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of bundle silk instrument, comprise that front end is fixed with the screw rod of drag hook, be set with slotted nut in the screw rod front portion, there have spring housing to be contained in screw rod to be outer and place between the positive stop end at slotted nut rear end and screw rod rear portion, described slotted nut comprises anterior bulge loop, the middle part snap ring with externally threaded nut and a plurality of flutings of rear portion band, have the tapped body of front end to be sleeved on outside the spring and be connected with nut thread, the fluting that is positioned at snap ring is provided with steel ball.

In the utility model, described body is wrapped with plastic wrapper, and this plastic wrapper surface is provided with the recess of being convenient to grasping.

The beneficial effects of the utility model are: when pricking silk, drag hook is caught on the colligation point, with pulling moving body, slotted nut and body together move backward, the spring of the snap ring at slotted nut rear portion compression simultaneously, make steel ball rectilinear motion and force screw rod to rotate in the fluting of slotted nut, thereby steel wire is tightened; After pulling work is finished, allow the resetting of spring in the body, body is travelled forward by the elastic force of spring, because slotted nut also was subjected to elastic force and travelled forward this moment, make the steel ball on it break away from fluting, but, steel ball can travel forward at the helicla flute of the thrust lower edge of spring end screw rod, finally travels back in the fluting of slotted nut, and this moment, screw rod can't reverse rotation, in the whole use, people need not break away from steel wire with drag hook, only need drag hook is colluded on steel wire, thereby by pulling body repeatedly the steel wire kink are tightened, use very light, convenient, improved operating efficiency greatly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of slotted nut in the utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, a kind of bundle silk instrument, comprise that front end is fixed with the screw rod 1 of drag hook 11, be set with slotted nut 2 in screw rod 1 front portion, there have spring 3 to be sleeved on screw rod 1 to be outer and place between the positive stop end 12 at slotted nut 2 rear ends and screw rod 1 rear portion, described slotted nut 2 comprises anterior bulge loop 21, the middle part snap ring 23 with externally threaded nut 22 and a plurality of flutings of rear portion band, have the tapped body 4 of front end to be sleeved on outside the spring 3 and be threaded with nut 22, the fluting that is positioned at snap ring 23 is provided with steel ball 5.

When pricking silk, drag hook 11 is caught on the colligation point, with pulling moving body 4, slotted nut 2 together moves backward with body 4, the snap ring 23 compression springs 3 at slotted nut 2 rear portions simultaneously make steel ball 5 rectilinear motion and force screw rod 1 to rotate in the fluting of slotted nut 2, thereby steel wire are tightened; After pulling work is finished, allow the resetting of spring 3 in the body 4, body 4 is travelled forward by the elastic force of spring 3, because slotted nut 2 also was subjected to elastic force and travelled forward this moment, make the steel ball 5 on it break away from fluting, but, steel ball 5 can travel forward at the helicla flute of the thrust lower edge of spring 3 ends screw rod 1, finally travels back in the fluting of slotted nut 2, and this moment, screw rod 1 can't reverse rotation, in the whole use, people need not break away from steel wire with drag hook 11, only need drag hook is colluded on steel wire, thereby by pulling body repeatedly the steel wire kink are tightened, use very light, convenient, improved operating efficiency greatly.

In the utility model, for the ease of grasping, described body 4 is wrapped with plastic wrapper 6, and these plastic wrapper 6 surfaces are provided with the recess of being convenient to grasping.

The utility model is rational in infrastructure, usefulness is convenient, improved a bundle silk operating efficiency greatly, is a kind of bundle silk instrument that is widely used in the civil engineering.
