Abstract
A kind of long-armed scissors of the utility model design, comprises handle, blade, connecting rod, tension arm and spring.Bearing pin is had in the middle of the handle of two, left and right, three connecting rods of scissors mid portion and four tension arm pins connect into two symmetrical parallelogram, the upper end of two connecting rods in both sides connects two blades in left and right by pin, and connected by pin in the middle of two blades, there is cutter tooth at two blade edge places.The utility model entirety is longer, can the transmission of realizable force by middle two parallelogram, thus reaches long-armed object, can cut the thing of higher position.
Description
Technical field
The utility model relates to a kind of scissors, particularly a kind of long-armed scissors.
Background technology
In life, topiary, branch etc. usually will use scissors, and the form of scissors is also varied, but when pruning the branch of eminence, flower and leaf, often because handle is too short etc., reason uses very inconvenient these scissors.So when pruning the branch of eminence, a reaping hook is often tied up and is used on a bamboo pole by people, very inconvenient.
Summary of the invention
In order to solve the problem, propose a kind of long-armed scissors.
The technical scheme that the utility model is taked is:
A kind of long-armed scissors, comprise handle, connecting rod, tension arm, pin, blade, two handles, the upper end of two handles respectively connects a connecting rod with pin, each connection tension arm simultaneously, the other end of these two tension arms is connected by pin, this pin connects intermediate connecting rod simultaneously, the upper end of left linkages respectively connects left blade and right blade by pin, these two pins are simultaneously each connects two tension arms, the other end of tension arm is connected by pin, and three connecting rods and four tension arms connect into two symmetrical parallelogram by pin.
Bearing pin between bearing pin between two described handles, upper and lower two pairs of tension arms and the bearing pin between two blades are point-blank.
The knife-edge part of two described blades has cutter tooth.
A spring is fixed with between two described handles.
The beneficial effects of the utility model are:
1. can transmitting force by two symmetrical parallelogram, make scissors can the thing of scissors higher position.
2. the knife-edge part of two blades has cutter tooth, makes scissors sharper.
3. be fixed with a spring between liang handle, make scissors in nature in the state of opening, use more convenient.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Embodiment
A kind of long-armed scissors, comprise handle, connecting rod, tension arm, pin, blade, handle has two, the upper end of two handles respectively connects a connecting rod with pin, each connection tension arm simultaneously, the other end of these two tension arms is connected by pin, this pin connects intermediate connecting rod simultaneously, the upper end of left linkages respectively connects left blade and right blade by pin, these two pins are simultaneously each connects two tension arms, the other end of tension arm is connected by pin, and three connecting rods and four tension arms connect into two symmetrical parallelogram by pin.
Bearing pin between bearing pin between two described handles, upper and lower two pairs of tension arms and the bearing pin between two blades are point-blank.
The knife-edge part of two described blades has cutter tooth.
A spring is fixed with between two described handles.
As shown in the figure, a kind of long-armed scissors, comprises blade 1, right connecting rod 6, intermediate connecting rod 7, left connecting rod 8, handle 10 and four tension arms.Wherein handle 10 has two, left and right, is connected in the middle of two handles by bearing pin 11.The top of handle 10 connects right connecting rod 6 and left connecting rod 8 by pin, these two pins connect a tension arm 13 and No. two tension arms 14 simultaneously respectively, these two tension arm other ends are connected by pin, this pin connects intermediate connecting rod 7 simultaneously, the upper end of right connecting rod 6 and intermediate connecting rod 7 is connected the two ends of No. three tension arms 16 respectively by pin, the upper end of left connecting rod 8 and intermediate connecting rod 7 is connected the two ends of No. 4 15 respectively by pin.Blade 1 has two, left and right, and the centre of these two blades is connected by pin 3, and the lower end of two blades connects the upper end of right connecting rod 6 and left connecting rod 8 respectively by pin.Three above-mentioned connecting rods and four tension arms form two symmetrical parallelogram.The two ends of spring 12 are separately fixed on two handles.The knife-edge part of blade 1 has cutter tooth 2.
Roughly operation principle of the present utility model is: when cutting the thing of eminence with this long-armed scissors, the thing that will cut snaps in the edge of a knife, firmly hold two handles 10, make the upper end move toward one another of handle 10, left connecting rod 8 and right connecting rod 6 are respectively to intermediary movements, and intermediate connecting rod 7 moves downward, because the distance between the pin 9 of the pin 4 of blade 1 lower end and handle 10 upper end is constant, so the lower end of blade 1 is close to each other, the edge of a knife closes, and is cut by object.Cutter tooth 2 on blade 1 makes blade 1 sharper.
The part do not addressed in the utility model adopts or uses for reference prior art and can realize.
In description of the present utility model, it will be appreciated that, orientation or the position relationship of the instruction such as term " " center ", " on ", D score, "front", "rear", "left", "right", " top ", " end " " interior ", " outward " they be based on orientation shown in the drawings or position relationship; be only the utility model and simplified characterization for convenience of description; instead of instruction or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
Claims (3)
1. a long-armed scissors, comprise handle, blade, connecting rod, tension arm and spring, it is characterized in that: the connecting rod in the middle of scissors and tension arm pin connect into two symmetrical parallelogram, intermediate connecting rod is the common edge of these two parallelogram, and the hypomere of connecting rod connects two handles by pin, is connected between two handles by pin, the upper end of connecting rod connects blade, is connected between two blades by pin.
