Abstract
The utility model relates to a pair of grafting scissors comprising a first handle, a second handle, a fixing knife base, a linkage rod, and a blade assembly. The first handle and the second handle are in pivot connection with each other, the fixing knife base is fixed on the first handle, the linkage rod is fixed on the second handle, and the blade assembly is arranged between the fixing knife base and the linkage rod. The fixing knife base, the linkage rod and the blade assembly are fixed together through an arc-shaped guide groove, a shaft hole of the linkage rod, and a longitudinal sliding groove of the blade assembly, wherein the arc-shaped guide groove penetrates through the fixing knife base through a shaft element. When the first handle and the second handle rotate in a pivot mode due to external force, the linkage rod is driven by the second handle to slide along the arc-shaped guide groove, the groove wall of the longitudinal sliding groove is pushed during a sliding process of the linkage rod to push the whole blade assembly to move toward the first handle, and therefore the aim of shearing to-be-grafted plants is achieved.

Embodiment
Please consult first Fig. 1 and Fig. 2, be the grafting shear 10 of the utility model the first preferred embodiment, include one first lever 20, one second lever 30, a trace 40, an elastic component 50, fixedly tool rest 60, an axle spare 70, and a blade assembly 80.
The top of the first lever 20 has the first perforation 22 that an operate portions 21 and runs through operate portions 21, the place has one first pivoted hole 23 in the middle of the first lever 20, the bottom of the first lever 20 has one first shank 24, use for the user and grip, in addition, the operate portions 21 of the first lever 20 is fixed with a chopping block 25.
The top of the second lever 30 has the second pivoted hole 32 that a clip slot 31, runs through clip slot 31, and a bottom that is communicated with connecting hole 33, the second levers 30 of clip slot 31 has the second shank 34 of relative first shank 24, uses for the user to grip.In when assembling, fill in by one first axle sleeve 35 between the second pivoted hole 32 of the first pivoted hole 23 of the first lever 20 and the second lever 30, so that first, second lever 20,30 can be pivoted relative to each other when being subject to External Force Acting.
The bottom of trace 40 has a draw-in groove 41 and one the 3rd pivoted hole 42, and the top of trace 40 has an axis hole 43, and axis hole 43 is elongated and have a bigger diameter end 432 and a miner diameter end 434 in the present embodiment.When assembling, the bottom of trace 40 is stretched in the clip slot 31 of the second lever 30, the first axle sleeve 35 can be filled in the 3rd pivoted hole 42, be located between the draw-in groove 41 of the connecting hole 33 of the second lever 30 and trace 40 by a clamping block 44 more simultaneously and finish the fixing of trace 40, so that trace 40 can be subjected to the drive of the second lever 30 and relative the first lever 20 pivot in unison.
Fixedly tool rest 60 has one first fixed part 61 and one second fixed part 62, the first fixed part 61 has one first fixing hole 612 and one second fixing hole 614, the second fixed part 62 has the arc guide barrel 624 that a storage tank 622, is communicated with storage tank 622, and the two horizontal guide grooves 626 that are positioned at arc guide barrel 624 upper and lowers.When assembling, be fixed in respectively the operate portions 21 of the first lever 20 by one first bolt 63 that is mutually locked and one first nut 64 and one second bolt 65 that is mutually locked and one second nut 66, wherein, the first bolt 63 is arranged in the first axle sleeve 35 and fixing the first fixing hole 612, the second bolts 65 of tool rest 60 and is arranged in the first perforation 22 of the first lever 20 and fixing the second fixing hole 614 of tool rest 60.
Axle spare 70 is located at and is connected trace 40 and fixedly between the tool rest 60 and have one second axle sleeve 71, one the 3rd bolt 72, and one the 3rd nut 73.The second axle sleeve 71 is arranged in the axis hole 43 of trace 40 and fixedly in the arc guide barrel 624 of tool rest 60, the 3rd bolt 72 has the body section 724 that a head 722 and is extended by head 722, the external diameter of head 722 is greater than the miner diameter end 434 of axis hole 43 and less than the bigger diameter end 432 of axis hole 43, body section 724 is arranged in the second axle sleeve 71 and stretches out the end that fixing tool rest 60, the three nuts 73 are locked on the body section 724 of the 3rd bolt 72 with its end.Thus, axle spare 70 can be subjected to trace 40 drive and along fixedly arc guide barrel 624 slippages of tool rest 60.
In use, hold first with one hand, the second lever 20,30 and force both mutually close, the axle spare 70 of this moment can be subject to the drive of trace 40 and operate portions 21 slippages along the arc guide barrel 624 of fixing tool rest 60 towards the first lever 20, simultaneously again can be along vertical chute 822 upwards slippages of movable tool rest 82, in the process of slippage, axle spare 70 can promote movable tool rest 82 by the cell wall of the vertical chute 822 of ejection, force whole blade assembly 80 by the guide function of this two guide member 86 swimmingly towards operate portions 21 slippages of the first lever 20, until being resisted against chopping block 25, blade 84 namely finishes shear action, as shown in Figure 4.In case discharge when bestowing first, second lever 20,30 strength, first, second lever 20,30 just can be subject to the effect of elastic component 50 and return back to the state that opens, blade assembly 80 also can be got back to position originally simultaneously, as shown in Figure 3.
When not using, hurt the user for fear of blade 84, as shown in Figure 5, the place arranges a breach 26 in the middle of the first lever 20, locate to be pivoted positioning piece 36 in the middle of the second lever 30, after finishing using, can the first application of force first, second lever 20,30 be remained on the use state, then force an end of keeper 36 to be connected in the breach 26 of the first lever 20, can't be pivoted relative to each other between first, second lever 20,30 of this moment, in order to promote the safety under the unused state.
When if the user runs into the situation of allowing blade replacement 84 more, as shown in Figure 6, remove respectively first the locking condition between the first bolt 63 and the first nut 64 and the second bolt 65 and the second nut 66, then just can down move fixedly tool rest 60 and blade assembly 80, allow the head 722 of the 3rd bolt 72 of axle spare 70 move to the bigger diameter end 432 of the axis hole 43 of trace, because the external diameter of the head 722 of the 3rd bolt 72 is less than the bigger diameter end 432 of axis hole 43, so the user can allow the 3rd bolt 72 of axle spare 70 break away from the axis hole 43 of trace 40 and pull down fixedly tool rest 60 and blade assembly 80 easily, just can carry out the replacing action of blade 84 this moment.
On the other hand, structure of the present utility model can have different the variation, and for example the axis hole 43 of trace 40 differs and is decided to be strip, also can be general circular port, as shown in Figures 7 and 8, and head 722 external diameters of the 3rd bolt 72 of axle spare 70 are exposed to outside the axis hole 43 greater than the external diameter of axis hole 43.In the case, when allowing blade replacement 84 more, except to remove locking condition between the first bolt 63 and the first nut 64 and the second bolt 65 and the second nut 66, also to remove the 3rd bolt 72 of axle spare 70 and the locking condition between the 3rd nut 73, take off again at last the second axle sleeve 71, as shown in Figure 8, tool rest 60 and blade assembly 80 reach the more purpose of allowing blade replacement 84 in order to can pull down smoothly fixedly.
In sum, the design of grafting shear 10 of the present utility model allows overall structure seem quite light and handy and is convenient for carrying, in use also as long as the several bolts of dismounting and nut just can carry out the more action of allowing blade replacement 84 according to actual needs, do not need to prepare again in addition grafting shear with different blade shapes, so can reach effective reduction cost and increase the purpose of ease of use.
