Abstract

The utility model discloses a wire cutting pliers used to cut things like reinforcing steel bars mainly comprising a pair of cutter heads and a pair of handles, wherein, the cutter heads and the handles are mutually hinged through connecting pin shafts, the two cutter heads are flexibly connected by a connecting plate and pin shafts of the connecting plate, the two handles are hinged through handle pins; the handle is also provided with a labor saving control device mainly comprising components such as a gear, a rack, a front push rod and so on; with the wire cutting pliers, when the operator operates, the pliers can cut in a section and step way without need to be operated like traditional wire cutting pliers which must be used continuously, so the operation is very labor saving.

Description

Bolt clipper

Technical field

The utility model relates to a kind of bolt clipper that is used for objects such as shear reinforcement.

Background technology

Bolt clipper is widely used in the industries such as five metals, construction, in order to shear objects such as iron wire, reinforcing bar, traditional bolt clipper mainly is made up of a pair of cutter head and a pair of handle, cutter head is hinged by being connected bearing pin with handle, connecting plate and connecting plate bearing pin are movably connected two cutter heads, and two handles also are hinged by handle pin; Its operation principle is: when needing to shear object, open two handles, two cutter heads also and then open, object is put between the cutting edge of two cutter heads, and the handle that firmly closes then, two cutter heads also and then close up, till object is cut off.The shortcoming of the bolt clipper of said structure is: the operator must firmly could cut off object at a dash, particularly when shearing thicker object, needs bigger strength, and operation is effort very.

Summary of the invention

Labour-saving bolt clipper relatively when the utility model will provide a kind of shearing manipulation.

For achieving the above object, bolt clipper described in the utility model mainly is made up of a pair of cutter head and a pair of handle, and cutter head is hinged by being connected bearing pin with handle, connecting plate and connecting plate bearing pin are movably connected two cutter heads, and two handles also are hinged by handle pin; On handle, also be provided with province's force operator.

Province recited above force operator is: be hinged with sheath body in a handle, a toothed rack is arranged in the sheath body, and an end and another handle of tooth bar are hinged, and also are hinged with gear in the sheath body, and wheel and rack is meshing with each other; One end of preceding push rod is hinged on the handle by preceding push rod bearing pin, and on the push rod bearing pin, stage clip suppressed the other end of preceding push rod on gear before stage clip was arranged on; Locking tooth is hinged in the sheath body by the locking tooth bearing pin, and an end of retaining spring is arranged on the sheath body, and the other end of retaining spring is arranged on the locking tooth, and the retaining spring suppresses locking tooth on gear.

The utility model has the advantages that: owing to increased province's force operator, operating personnel whenever close up handle once, before push rod just promote the gear certain distance that on tooth bar, rolls, make cutter head also and then close up certain distance, like this, operating personnel needn't firmly shear at a dash, but can segmentation shear step by step, and it is just very laborsaving to operate.

Fig. 2 is the structural representation of the province's force operator among Fig. 1;

Fig. 3 is that A among Fig. 2 is to the partial structurtes schematic diagram.

Embodiment

Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.

As shown in Figure 1, bolt clipper described in the utility model mainly is made up of a pair of cutter head 1 and a pair of handle 7, and cutter head 1 is hinged by being connected bearing pin 15 with handle 7, connecting plate 17 and connecting plate bearing pin 16 are movably connected two cutter heads 1, and two handles 7 also are hinged by handle pin 2; On handle 7, also be provided with province's force operator.

As shown in Figure 1 and Figure 2, province recited above force operator is: be hinged with sheath body 13 in a handle 7, in the present embodiment, sheath body 13 is hinged in this handle 7 by last sheath body bearing pin 14 and following sheath body bearing pin 5; One toothed rack 3 is arranged in the sheath body 13, one end of tooth bar 3 is hinged by tooth bar bearing pin 4 and another handle 7, also is hinged with gear 6 in the sheath body 13, in the present embodiment, gear 6 also is hinged in the sheath body 13 by following sheath body bearing pin 5, and gear 6 is meshing with each other with tooth bar 3; One end of preceding push rod 8 is hinged on the handle 7 by preceding push rod bearing pin 9, and as shown in Figure 3, on the push rod bearing pin 9, stage clip 18 suppressed the other end of preceding push rod 8 on gear 6 before stage clip 18 was arranged on; As shown in Figure 1 and Figure 2, locking tooth 10 is hinged in the sheath body 13 by locking tooth bearing pin 12, and an end of retaining spring 11 is arranged on the sheath body 13, and the other end of retaining spring 11 is arranged on the locking tooth 10, and retaining spring 11 suppresses locking tooth 10 on gear 6.

The operation principle of bolt clipper described in the utility model is: when needing to shear object, firmly open two handles 7, the lower surface 81 of push rod 8 withstands on the downside of locking tooth 10 before making, before push rod 8 interact with locking tooth 10, push rod 8 is all backed down with locking tooth 10 and is separated with gear 6 before making, like this, gear 6 can be to outer rolling on tooth bar 3, till two handles 7 opened up into correct position, at this moment, two cutter heads 1 also and then opened up into correct position; Object is put between the cutting edge of two cutter heads 1, two handles 7 then begin to close, at this moment, the lower surface 81 of preceding push rod 8 is separated with the downside of locking tooth 10, under the effect respectively of stage clip 18 and retaining spring 11, preceding push rod 8 and locking tooth 10 are all suppressed on gear 6, like this, when closing up handle 7, preceding push rod 8 just promotes gear 6 and move inward certain distance on tooth bar 3 under the drive of handle 7, drives two cutter heads 1 simultaneously and also inwardly shears certain distance, when two handles 7 are brought together into quite approaching position, outwards open two handles 7 again, owing to locking tooth 10 suppresses on gear 6, thereby gear 6 can not be to outer rolling on tooth bar 3, and preceding push rod 8 is along with outwards the moving of handle 7, also along circumferential outer mobile certain distance of gear 6; When two handles 7 open up into suitable position, close up two handles 7 once more, same, just promote gear 6 once more moves inward certain distance to preceding push rod 8 on tooth bar 3, also drives two cutter heads 1 and inwardly shears certain distance once more; Like this, constantly reciprocally open and close up two handles 7, just can progressively constantly two cutter heads 1 inwardly be closed up and shear object, till object is cut off.

Use the bolt clipper of said structure, when operating personnel operate, needn't must firmly shear at a dash as traditional bolt clipper, but can segmentation shear step by step, it is just very laborsaving to operate.
