Abstract

The utility model relates to a pair of hand wire clippers used for changing the holding power of a hand into the thrust force of a screw thread telescopic rod via the mechanism of the screw thread telescoping rod for cutting wires through a jaw. The jaw can be adjusted and repaired, and clipper handles are short The utility model can substitute the wire clippers in present market, and compared with the existing wire clippers, the hand wire clippers have the advantages of no environmental limitation, high durability, single hand operation, etc. The hand wire clippers can be used as a wire cutter for cutting wires in all walks of life.

Description

Single hand held bolt clipper

The utility model is a kind of with the singlehanded broken string instrument that can operate the cut-out wire rod.

As everyone knows, broken string instrument on the present market, bolt clipper, though bend nose bolt clippers is widely used in industry-by-industries such as civil engineering, military affairs, electric power, manufacturing, but it still exists following shortcoming, at first they all must with the hands make a concerted effort to operate, and can not vacate a hand and be used to control the not fixture of being cut, smallclothes thing etc.; Secondly, the bolt clipper on the market is in order to obtain maximum cut-out power, and the pincers handle is generally all very long, and the corresponding cost of giving is purchased, and it is flat unfavorable to carry each interarea band, and main is that applying environment is made huge restriction; In addition, the pincers sword of old-fashioned bolt clipper can not be repaired after wear and rupture, and miscellaneous part is discarded in the lump thereupon.

The utility model will provide a kind of exactly and can manipulate with one hand, volume is not more than palm, as long as it just can finish the cut-out task there the place that palm can arrive, and the pincers sharpening at it decreases, can change other place of incisions after the fracture or simply repair after the new-type bolt clipper that can heavily use.

The utility model is achieved in that and at first removes the long pincers handle of old-fashioned bolt clipper, use the small forceps handle instead and the grip of palm at first is transformed into the torsion of double thread expansion link by it, screw thread expansion link by elongation removes to act on jaw, cuts off wire rod once.Secondly two jaws all to be made upper and lower surface have sword, and all there is identical connecting hole front and back, and center symmetric figure jaw makes its certain can continue normal use by changing intact blade after wear and rupture.

The utility model is compared with other broken string instrument to have one hand and can manipulate, and not limited by operating environment, durable at the bottom of the cost, can repair, small and exquisite advantage such as portable.

Below in conjunction with an embodiment who describes in the accompanying drawing the utility model of explaining.

Figure of description is a side view of the present utility model.

Lower clamp nozzle (1) with reference to the accompanying drawing bolt clipper is identical with upper clamp nozzle (2), all be that upper and lower surface has sword (3), left-right symmetry, there is identical connecting hole (4) at two ends, it just can be arbitrarily and the corresponding connecting hole (5) on the overcoat of screw thread expansion link (8) like this, tong holder connecting hole (6) (7) connects with pin, when certain part appearance fracture of pincers swords (3), can continue to cut off by the intact pincers blade branch of another side or other end that uses the pincers sword after the wearing and tearing.

(11) are the two ratchets that collude that can stir on flexible handle (12) among the figure, when cutting off, the interior pawl of ratchet (11) is pushed into the position of touching mutually with ratchet (10), hold with a firm grip flexible handle (12) with because of deciding handle (14) generation torsion, drive expansion link internal diameter (9) by counterclockwise rotating, the expansion link elongation, effect upper clamp edge (2) removes to cut off wire rod, wherein (16) rotating for its restriction lower clamp nozzle (1) of lower clamp nozzle baffle plate.

In the time of after wire rod is cut off, will separately going up lower clamp nozzle, as long as the position that the outer pawl that two-way ratchet (11) is pushed into it and ratchet (10) touch mutually, after with palm flexible handle (12) and fixed handle (14) being held with a firm grip, utilize the reset force of back-moving spring (13), effect flexible handle (12) resets, and drives expansion link internal diameter (9) simultaneously, and it is moved in the direction of the clock, expansion link shortens, and hauls upper clamp nozzle (2) and separates with lower clamp nozzle (1).

Claims (3)

1, is used for the broken string instrument that one-handed performance cuts off wire rod, with the screw thread expansion link hand is supportted the cut-out power that grip is transformed into jaw, feature of the present utility model is, one end of screw thread expansion link link to each other with upper clamp nozzle the other end by can tuning on a ratchet and the flexible handle twoly collude ratchet and link to each other, a back-moving spring is arranged on the flexible handle, jaw is that the two sides has sword, and there is respective connecting front and back.Expansion link has on the pincers seat to be used for connecting the connecting hole that jaw is used, groove, and be used for limiting the baffle plate that lower clamp nozzle rotates.

According to the bolt clipper of the described single hand held of claim 1, it is characterized in that 2, last lower clamp nozzle is identical, all is that upper and lower surface has sword, and there is the jaw of the center symmetric figure of identical connecting hole front and back.

3, according to the described single hand held bolt clipper of claim 1, it is characterized in that expansion link is a screw-type.
