The utility model is realized above-mentioned purpose by the following technical solutions: a kind of Iron shears material pressing device, comprise, under cut body, cut handle, also comprise stay cord, holding pad, the binder pillar, the binder lever, fixed block, stage clip, the depression bar drag hook, draw ring resets, sleeve, brake bar, brake bar support and transmission levers, wherein: fixed block is fixed in cuts body one side, sleeve is fixed on the fixed block, sleeve is provided with slideway, its inside also is provided with the binder pillar with slideway, the stage clip of this binder pillar upper end socket touches mutually with the sleeve top, the lower end is connected with holding pad, be connected with the brake bar support on the lower cartridge front-back respectively, be provided with brake bar between the two, being provided with spring between this brake bar one end and the brake bar support also is connected and fixed with axle, the other end touches mutually with the braking line of binder pillar bottom, be respectively equipped with the drag hook support corresponding on the upper cartridge front-back with the brake bar support, be connected with depression bar drag hook and driving connecting rod with axle between this drag hook support, the depression bar drag hook passes the slideway of binder pillar, with be fixed on brake bar on the draw ring hook joint mutually that resets, driving connecting rod and two transmission levers are fixed on axle and cut on the body, the steady pin of the fixed conveyor lever other end touches mutually with the binder lever, the lower end of binder lever is fixed on and cuts on the body with axle, its upper end by stay cord with cut handle and be connected.

Compared with prior art, the beneficial effects of the utility model are: this material pressing device that is used for Iron shears is simple in structure, easy to operate, time saving and energy saving, can effectively solve tipping, cut problems such as body damage, brake device structure is tight, good braking effect, broad view, be convenient to user operation, long service life, function are complete.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is that A-A is to view.

Among the figure: binder lever 1, stage clip 2, binder pillar 3, transmission levers 4 is cut 5, stay cord 6, driving connecting rod 7, depression bar drag hook 8, drag hook support 9, sleeve 10, holding pad 11, braking line 12, brake bar 13, brake bar support 14, the draw ring 15 that resets, fixed block 16, steady pin 17.

The specific embodiment

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

Referring to accompanying drawing, in the present embodiment, fixed block 16 is welded on a side of cutting body, sleeve 10 is welded on the fixed block 16, sleeve 10 is provided with slideway, and the binder pillar 3 with slideway also also is equipped with in its inside, these binder pillar 3 upper ends also are socketed with stage clip 2, the bottom of stage clip 2 touches mutually with the top of sleeve 10, when not using this material pressing device, stage clip 2 is a relaxation state, the lower end of binder pillar 3 is welded with rectangle holding pad 11, before sleeve 10 bottoms, be welded with triangle brake bar support 14 on the back respectively, between the two brake bar supports 14 brake bar 13 is housed, being provided with spring between one end of brake bar 13 and the brake bar support 14 also is connected and fixed with axle, the other end touches mutually with the braking line 12 that is positioned at binder pillar 3 bottoms, before sleeve 10 tops, be welded with respectively on the back and brake bar support 14 corresponding drag hook supports 9, be connected with depression bar drag hook 8 and driving connecting rod 7 between this two drag hooks support 9, and be fixed in connecting axle and cut on the body, depression bar drag hook 8 passes the slideway on the binder pillar 3, with be fixed on brake bar 13 on draw ring 15 hook joint mutually that resets, the other end of driving connecting rod 7 and two transmission levers, 4 usefulness axle are fixed on to be cut on the body, these transmission levers 4 other ends are connected and fixed with steady pin 17, and this steady pin 17 touches with binder lever 1, the lower end of binder lever 1 is fixed on by axle and cuts on the body, and its upper end is connected 5 with cutting by stay cord 6.

Concrete using method of the present utility model is as follows: the reinforcing bar that will need to shear places between two cutting edges, hand is pinched and is cut 5, stay cord 6 drives 1 rotation of binder lever under spring action, binder lever 1 promotes transmission levers 4 and rotates, at the drive down-pressed pole drag hook 8 of driving connecting rod 7 with its motion, binder pillar 3 is depressed, thereby clamping sleeve is connected on the stage clip 2 on binder pillar 3 tops, unclamp the draw ring 15 that resets simultaneously, under the effect of spring, brake bar 13 is adjacent to binder pillar 3 and inconsistent with braking line 12 automatically, when the material that is sheared upwarps, brake bar 13 meeting Braking mode, to reach the purpose that compresses material, brake bar support 14 plays the fixedly effect of brake bar 13; When unclamping when cutting, under the effect of each spring, each parts can automatically restore to initial position.
