Abstract
The utility model discloses a labor-saving wire clipper which comprises handles, blades and connecting pin rotating shafts and is characterized in that a limiting pressure plate 4 is movably connected with both sides of a blade 1, a blade 2 and the rotating shafts 3 through bolts 5, a bracing mandril 7, the blade 1 and a bracing mandril 8, and the bracing mandril 7, the blade 2 and another bracing mandril 8 are movably hinged through a pin rotating shaft 6; the bracing mandril 7 and a bracing mandril 10, the bracing mandril 7 and a bracing mandril 11, the bracing mandril 8 and the bracing mandril 10, and the bracing mandril 8 and the bracing mandril 11 are all movably hinged through a pin rotating shaft 9; the bracing mandril 10 and the bracing mandril 11 are movably hinged in a cross position through a pin rotating shaft 12, and the bracing mandrils 8 at both sides are respectively connected with a handle 13 and a handle 14. The utility model has simple structure, low cost, convenient and easy operation, is suitable for common use for benefits and saves labor so that a crowd with weak hand power, such as old people or children, and the like, all have enough abilities to use the tool.
Description
Technical field
The utility model relates to a kind of hand-operated tools, especially pliers.
Background technology
The pliers that can be applicable to clamping at present, clamps, cuts off bar has much, structure and shape are varied, are widely used, and generally all comprise handle and jaw, between handle and jaw, be provided with rotational structure, control the jaw clamping, clamp, cut off object by operating grip.But the pliers that can cut off iron wire about Φ 8mm or reinforcing bar easily is few, and complex structure, product that cost is high are arranged, as motorized stage vice, hydraulic tongs etc., thus be not suitable for generally using, and the most frequently used bolt clipper still is gruelling, some crowd is have more than is needed.
Summary of the invention
The utility model has been designed a kind of more labour-saving pliers, can cut off iron wire or reinforcing bar about Φ 8mm easily, and is simple in structure, cost is low, simple operation easily, is generally used preferably.It is characterized in that: spacing pressing plate 4 connects by bolt 5 activities on the limit, the left and right sides of blade 1 and blade 2 and rotating shaft 3, support bar 7 and blade 1 and support bar 8, support bar 7 and blade 2 and support bar 8 all are movably hinged by pin rotating shaft 6, support bar 7 and support bar 10, support bar 7 and support bar 11, support bar 8 and support bar 10, support bar 8 and support bar 11 all are movably hinged by pin rotating shaft 9, support bar 10 and support bar 11 crossover locations are movably hinged by pin rotating shaft 12, link with handle 13 and handle 14 respectively at left and right sides support bar 8.
The pliers of said structure is the power arm of input power with handle 13 and handle 14, fulcrum and resistance arm that pin rotating shaft 6 and pin rotating shaft 9 all contain for lever are laminated, make the support bar 10 and the support bar 11 of flexible connection be closed up the pushing of outside both sides by mutual cramping, support bar 7 that flexibly connects and support bar 8 are closed up outside both sides equally and are pushed to blade 1 and blade 2, and resistance point is very little, the leverage that the stressed composition that is laminated links up is so can obtain laborsaving shearing force greater than the active force manyfold at blade 1 and blade 2.
Description of drawings
It among Fig. 1 the utility model pliers expanded configuration schematic diagram.
It among Fig. 2 the utility model pliers closing structure schematic diagram.
The specific embodiment
Spacing pressing plate 4 passes through bolt 5 link joints (this is similar to general bolt clipper cutting nippers) on the limit, the left and right sides of blade 1 and blade 2 and rotating shaft 3.Support bar 7 and blade 1 and support bar 8, support bar 7 and blade 2 and support bar 8 are movably hinged by pin rotating shaft 6 all that (support bar 7 and blade 1 and support bar 8 or support bar 7 and blade 2 and support bar 8 have respective through hole to rotate common technology for pincers class etc. in pin rotating shaft 6, illustrating can be very clear, simple, known, so need not to analyse and observe or tell about in mapping).Support bar 7 and support bar 10, support bar 7 and support bar 11, support bar 8 and support bar 10, support bar 8 and support bar 11 all are movably hinged by pin rotating shaft 9, support bar 10 and support bar 11 crossover locations are movably hinged by pin rotating shaft 12, link with handle 13 and handle 14 respectively at left and right sides support bar 8.
The operation principle and the using method of the utility model pliers are: handle 13 and handle 14 are stressed when inwardly exerting pressure, (pin rotating shaft 6 is extrapolated for rotating shaft 6 of passive some pin and pin rotating shaft 9 changes, support bar 10 or support bar 11 are being pressed in pin rotating shaft 9) the support bar 10 that flexibly connects and support bar 11 closed up the pushing of outside both sides by cramping mutually, support bar 7 that flexibly connects and support bar 8 close up outside both sides pushing blade 1 and blade 2 equally, because fulcrum and resistance arm that support bar 6 and support bar 9 all contain for lever press work, handle 13 and handle 14 are the power arm of input power, and can see that to draw resistance point very little, the leverage that the stressed composition that also is laminated links up, make at blade 1 and blade 2 and obtain shearing force greater than the active force manyfold, very laborsaving.
