Embodiment
Please first consult Fig. 1 and Fig. 2, the orchard shears 10 of the utility model the 1st embodiment includes two lever 20, trace 30,1 first cutting edge 40,1 second cutting edges 50, and a control unit 60.
The top of one of them lever 20 is fixed in the bottom of trace 30.
First cutting edge 40 has one first blade 41, linkage part 42, and a cantilever portion 43.The bottom of the first blade 41 is articulated in the top of trace 30 by a pivot 44, linkage part 42 is extended from the bottom of the first blade 41 and is connected to the top of another one lever 20, and cantilever portion 43 is extended towards the direction of trace 30 from the inner peripheral of linkage part 42.
Second cutting edge 50 has one second blade 51 and a resisted position 52.The bottom of the second blade 51 is articulated in the bottom of the top of trace 30 and the first blade 41 of the first cutting edge 40 by pivot 44, resisted position 52 is extended towards the direction of the cantilever portion 43 of the first cutting edge 40 from the bottom of the second blade 51 and is had a groove 53, and the length of groove 53 is greater than the half length of the resisted position 52 of the second cutting edge 50 in the present embodiment.
Control unit 60 has arc guide member 61 and a guide wheel 63.Trace 30 is fixed in one end of arc guide member 61, and the other end of arc guide member 61 extends towards the direction of the first cutting edge 40, and the apical margin of arc guide member 61 has a teeth portion 62; Guide wheel 63 has gear 64 and a wheel cap 65, gear 64 be hubbed at the end of the cantilever portion 43 of the first cutting edge 40 and bridle joint in the teeth portion 62 of arc guide member 61, wheel cap 65 is coaxially connected to gear 64 towards a side of the second cutting edge 50 to be had an extension 66 and and guides protuberance 67, and guiding protuberance 67 is located at the end of extension 66 and is embedded in the groove 53 of the resisted position 52 of the second cutting edge 50.
From said structure, when two levers 20 being pulled out from an initial position P1 towards an expanded position P2 when exerting a force, first the first cutting edge 40 can be rolled towards the direction away from trace 30 along arc guide member 61 by cantilever portion 43 driven gear 64, as shown in Figure 2, meeting driven wheel lid 65 pivotable simultaneously in the process that gear 64 rolls, make wheel cap 65 guiding protuberance 67 can simultaneously the groove 53 of ejection second cutting edge 50 right side cell wall and along the groove 53 up slippage of the second cutting edge 50, thus, second blade 51 of the second cutting edge 50 just can gradually towards the first blade 41 away from the first cutting edge 40 direction pivotable and and present open configuration gradually between the first blade 41 of the first cutting edge 40.When gear 64 is rolled to arc guide member 61 central, as shown in Figure 2, the guiding protuberance 67 of wheel cap 65 also just can be positioned at the central authorities of the groove 53 of the second cutting edge 50, now can form maximum opening angle between the first blade 41 of the first cutting edge 40 and the second blade 51 of the second cutting edge 50, when then continuing again to pull out two levers 20, gear 64 can continue to roll towards the direction away from trace 30, and, wheel cap 65 also can continue along with gear 64 pivotable, wheel cap 65 at this time can by the left side cell wall of the groove 53 of guiding protuberance 67 ejection second cutting edge 50 and along groove 53 up slippage, thus, second blade 51 of the second cutting edge 50 can gradually towards the first blade 41 pivotable of the first cutting edge 40, the end of arc guide member 61 is rolled to once gear 64, as shown in Figure 3, the guiding protuberance 67 of wheel cap 65 can be positioned at the top of the groove 53 of the second cutting edge 50, namely two levers 20 are now positioned at expanded position P2, primary shear action is completed together with abutting against one another between first blade 41 of the first cutting edge 40 at this time and the second blade 51 of the second cutting edge 50.
After completing a shear action, then exert a force two levers 20 again from expanded position P2 towards initial position P1 toward interior promotion, in pushing course, first the first cutting edge 40 can roll along arc guide member 61 towards the direction of trace 30 by driven gear 64, in the process that gear 64 rolls, the guiding protuberance 67 of wheel cap 65 can the cutting edge of ejection second simultaneously 50 groove 53 right side cell wall and along the groove 53 down slippage of the second cutting edge 50, make to open gradually between the second blade 51 of the second cutting edge 50 and the first blade 41 of the first cutting edge 40, when gear 64 is rolled to arc guide member 61 central (as shown in Figure 2), maximum opening angle can be formed between first blade 41 of the first cutting edge 40 and the second blade 51 of the second cutting edge 50, then continue again inwardly to promote two levers 20, make the guiding protuberance 67 of wheel cap 65 continue the groove 53 of ejection second cutting edge 50 left side cell wall and along groove 53 down slippage, second blade 51 of the second cutting edge 50 at this time can gradually near the first blade 41 of the first cutting edge 40, when two levers 20 are positioned at initial position P1 as shown in Figure 1, secondary shear action is completed together with again abutting against between first blade 41 of the first cutting edge 40 and the second blade 51 of the second cutting edge 50.
From the above, orchard shears 10 of the present utility model can order about first when two levers 20 are switched to expanded position P2 from initial position P1, second cutting edge 40, 50 carry out a shear action, first can be ordered about again again time in addition from expanded position P2 involution to initial position P1, second cutting edge 40, 50 carry out a shear action, that is, order about first operating two levers 20 in One step development and the process that folds always to meet together, second cutting edge 40, 50 carry out twice shear action, so compared with prior art, orchard shears 10 of the present utility model operates more laborsaving, operating efficiency also can there is obvious lifting, and then can the purpose of this utility model be reached.
On the other hand, the utility model structurally can have different changes, as shown in Figures 4 and 5, the length of the groove 73 of the second cutting edge 70 shortens into the half length of the resisted position 72 being less than the second cutting edge 70 in the 2nd embodiment, simultaneously in order to coordinate the length of groove 73, wheel cap 83 structurally dispenses the design of extension, the guiding protuberance 84 of wheel cap 83 is set directly at the side of wheel cap 83 towards the second cutting edge 70, thus, the shift motion of half can be shortened in the process that the guiding protuberance 84 of wheel cap 83 rolls along arc guide member 80 at gear 82, in order to reduce the opening angle between the first blade 41 of the first cutting edge and the second blade 71 of the second cutting edge 70, and then meet different user demands.
