Abstract
The utility model relates to a kind of scissors, especially a kind of scissors with a roller structure. Two bodies with a blade are used and pinned via a pin shaft blade symmetrically. Two or above rollers are provided between the blades of both bodies, in which one body blade has a pair of roller sockets for accommodating the rollers. Since a roller serving as a bearing is provided between the blades of both bodies, and a roller socket that prevents the roller from coming off is provided on the blade of one body, the traditional axle tree friction mode between the body blades of the prior scissors is turned into rolling friction, reducing resistance greatly and saving effort greatly during cutting.
Description
Technical field
The utility model relates to a kind of scissors, particularly a kind of scissors with roller structure.
Background technology
The scissors of people's use at present is two and cuts body, each only cuts body one end is the handle of a ring-type, the other end is the cutter head that has cutting edge on one side, there is a pin shaft hole at the middle part, from cutting the principal plane of body, a face is the sword face with cutting edge, and another face is the outside that does not have the sword face, two are cut body is that the sword face relatively uses bearing pin hinged, thereby can shear being cut thing.
Existing scissors is in manufacture process, if bearing pin is long, can paste not tight very effort mutually because of two cutting edges during shearing; If bearing pin is too short, effort when not only shearing, also effort very when cutting a cutter and opening has this old man or children even can't open scissors at all.
Summary of the invention
The purpose of this utility model is a shearing of design and opens all labour-saving very, has the scissors of roller structure.
For achieving the above object, the utility model adopts following technical solution:
Still adopt two bodies of cutting with sword face, two cut body by bearing pin sword face pin joint relatively, cut the roller that is equipped with between body sword face more than two or two two, wherein cut body sword face the roller nest that holds roller is one to one arranged for one.
By above scheme as seen, owing to cut the roller that has been provided with the bearing effect between the sword face of body two, and prevent the roller nest that roller comes off a sword face setting of cutting body, thereby changing existing scissors, to cut the traditional approach of axle dry friction between the body sword face be the rolling friction mode, resistance reduces greatly, and is very laborsaving during shearing.
Description of drawings
Fig. 1 is the construction profile figure of embodiment;
Fig. 2 is the sword face figure who cuts body that embodiment has the roller nest;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 dissects the plane outspread drawing of cutting body along roller nest place circular arc line.
Be described further below in conjunction with embodiment and accompanying drawing thereof.
Embodiment
Referring to Fig. 1, cut body 1 and cut body 3 and be assembled into a scissors by bearing pin 2, cutting body 3 among the figure visible is the outside, and cuts the part that body 1 can only be seen sword face scissors handle.
Referring to Fig. 2, this is a sword face figure who cuts body wherein, three roller nests 11,12,13 are arranged on the isocentric circular arc of sword face pin shaft hole 13, when being assembled into scissors, the man-to-man roller of inserting in the roller nest, as seen from the figure, three roller nests 11,12,13 all be positioned at the scissors closure state descend perpendicular to the scissors center line cross a straight line 14 lean on scissors a side, just illustrated left, this helps fitting tightly of scissors cutting edge.
Referring to Fig. 3, bearing pin 2 caps and cut between body 3 outsides bearing 4 is arranged, in this example, bearing 4 is plain thrust bearings.The right of Fig. 3 is a cutting edge of cutting body 1,3, and the left side is a scissors handle of cutting body 1,3, for simplicity, omits cutting edge and scissors handle among Fig. 3.Closely has darker size from the roller nest of crossing axle straight line 14, have more shallow size away from the roller nest of crossing the axle straight line, therefore, roller 5 exceeds that to cut body 1 sword face some more, roller 6 exceeds that to cut body 1 sword face few, and this makes that cutting body 1,3 can fit better on the cutting edge limit.Threaded engagement between bearing pin 2 and the nut 7, when actual assembled, adjust to the optimum state of bearing pin 2 length after, can adopt known retaining modes such as gluing, double nut to carry out lock nut 7, in case the undesired axial elongation of shotpin axle 2.
Referring to Fig. 4 and in conjunction with Fig. 2, roller nest 12,15 is near from crossing axle straight line 14, and the degree of depth that they deeply cut body is just big, and roller nest 11 away from a straight line 14, the degree of depth that it deeply cuts body is just littler.
Technical conceive of the present utility model is not limited in the foregoing description, under same design multiple structural change can be arranged, such as, roller can also be roller or platform shape roller except that being the ball; The scissors outside can also be gone up the annular groove at least one face and be placed the roller in the annular groove to form with the bearing between the bearing pin cap by bearing pin cap and relative scissors outside, like this, can save plane bearing parts, reduces cost.This can also be the bearing that has roller bracket by the bearing as bearing body outside bearing pin cap and the scissors, and this is more conducive to assembling.
