Description

A kind of branch is cut

[technical field]

The utility model is relevant a kind of orchard shears of shearing thing such as branch, refers to especially a kind ofly be easy to the application of force and the labour-saving branch is cut.

[background technology]

A kind of effort-saving branch with labor-saving structure is as shown in Figure 5 cut, this branch clipper has one first lever 5 and one second lever 6, the front end of this first lever 5 has one first blade 51, and

first blade

51 and 5 of first levers have one first pin joint 52 and one second pin joint 53, this first pin joint 52 is to be used for the stage casing of hinged cutting edge 7, this second pin joint 53 is to be used for the front end of hinged this second lever 6, and this cutting edge 7 has extended upward one second blade 71, and the tail end of this cutting edge 7 has one the 3rd pin joint 72, and the leading portion of this second lever 6 has one the 4th pin joint 61, be with a connecting rod 8 hinged joints between the 3rd pin joint 72 and the 4th pin joint 61, and form the labor-saving structure of four connecting rod states.

Therefore, when shearing, this second lever 6 can move by drivening rod 8 to the inside, and the tail end that 8 on this connecting rod can drive this cutting edge 7 rotates, and is axle and make second blade 71 of cutting blade sheet 7 with this first pin joint 52, does the action of shearing to this first blade 51.

Because it mainly is with first that this branch is cut, two, three, four

pin joints

52,53,72,61 the state that is connected to form four connecting rods, and reach the labour-saving effect, and this branch to cut be to utilize connecting rod 8 that the motion of second lever 6 is conveyed to this cutting edge 7, rotate to drive this cutting edge 7, but when the quadric chain transmission, have the dead point of certain angle, if the angle that this second lever 6 and this connecting rod are 8 is more near the dead point angle, then be not easy the application of force more, as shown in Figure 6, when this branch is cut when pruning thicker branch 9, the aperture that its first lever 5 and second lever are 6 can be big more, thus, the angle θ that can make 8 on this second lever 6 and connecting rod is more near the dead point, drives this connecting rod 8 cutting edge 7 is rotated and cause this second lever 6 to be difficult for the application of force, and it is very painstaking to make when pruning thicker branch 9.So above-mentioned branch is cut the disappearance that is difficult for the application of force, and further improved necessity is arranged.

[utility model content]

Main purpose of the present utility model, be to solve the above problems and provide a kind of in shear history easily the branch of the application of force cut.

A kind of branch of the utility model design is cut and is included one first lever, one second lever and a swing component, the top of this first lever extends upward one first blade and is hinged on the stage casing of swing component, one end of this swing component has one second blade, the other end is then hinged with this second lever, and connecting the first blade place, first lever has one first pin joint, for hinged swing component, and first lever has one first tooth portion in the bottom of first blade, and the top of second lever has intermeshing second a tooth portion of the first tooth portion with first blade, and second lever protrudes out one second pin joint in this first lever of following direction of this second tooth portion, and this swing component relatively a section of this second blade have a chute, hinged and slide for second pin joint of this second lever along this chute.

Because this second lever is when driving this swing component rotation, be by the transmission that is meshing with each other of this first tooth portion and this second tooth portion, drive this swing component rotation and make this second lever be easy to the application of force, especially when pruning thicker branch, this second lever nationality is by this second tooth portion and the first tooth portion engaged transmission, and still the application of force is sheared the fat tree branch easily.

And, in the linkage section of this swing component, has chute, and second pin joint of this second lever can be in this chute sliding transfer, and can change the length of this swing component arm of force, to adapt to the moment of different phase, and add the engaged transmission of the first tooth portion and the second tooth portion, and can reach laborsaving effect.

[embodiment]

Seeing also 1 figure to Fig. 3, is the selected example structure of the utility model shown in the figure, and this example only for the usefulness of explanation, is not subjected to the restriction of this kind structure in patent application.

A kind of laborsaving branch of the utility model design is cut, and includes one first lever 1, second lever 2 and a swing component 3, wherein:

The top of this first lever 1 has extended upward one first blade 11, and this first lever I connects these first blade, 11 places and has one first pin joint 12, and the bottom of this first blade 11 has one first tooth portion 13, in the present embodiment, this first tooth portion 13 directly offers most conformality teeth along the bottom margin of this first blade 11.

The top of this second lever 2 has second a tooth portion 21 of meshing with the first tooth portion 13 of this first blade 11, in the present embodiment, this second meshing 21 is directly to offer most conformality teeth along the tip edge of this second lever 2, for forming the form of external gears with this first tooth portion 13, and this first tooth portion 13 is connected with a connection piece 23 with 21 in the second tooth portion, in the present embodiment, this connector 23 is to be plates, the one end is the home position that is articulated in these first tooth portion, 13 place circular arcs, the other end then is articulated in the home position of these second tooth portion, 21 place circular arcs, and this second lever 2 protrudes out one second pin joint 22 in this first lever 1 of following direction of the second tooth portion 21.

This swing component 3 is first pin joints 12 that are articulated in this first lever 1 with middle section position, and it is one second blade 31 that an end of this swing component 3 extends upward, the other end then extends to a linkage section 32 downwards, has one chute 33 in this linkage section 32, and second pin joint 22 of this second lever 2 is to be articulated in this chute 33, and slides along this chute 33.

By this first lever 1 of mutual grip pressure and second lever 2, make this first lever 1 and this second lever 2 with the transmission that is meshing with each other of the first tooth portion 13 and the second tooth portion 21, second pin joint 22 of second lever 2 is moved in swing component 3 chutes 33, rotate to drive this swing component 3, make 11 one-tenth staggered shear action of first blade of second blade 31 with first lever 1 of this swing component 3, and prune flowers and trees.

Because this second lever 2 is when driving these swing component 3 rotations, be by the transmission that is meshing with each other of this first tooth portion 13 and this second tooth portion 21, as shown in Figure 4, drive this swing component 3 rotations and make this second lever 2 be easy to the application of force, especially when pruning thicker branch 4, this second lever 2 is by the engaged transmission of this second tooth portion 21 and first meshing 13, and still the application of force is sheared fat tree branch 4 easily.

Moreover, has chute 33 in the linkage section 32 of this swing component 3, and second pin joint 22 of this second lever 2 can be in this chute 33 sliding transfer, and can change the length of these swing component 3 arm of forces, adapting to the moment needs of different phase, and add the engaged transmission of the first tooth portion 13 and the second tooth portion 21 and can reach laborsaving effect.

The announcement of the above embodiment is in order to explanation the utility model, is not in order to restriction the utility model, so the displacement of the change of numerical value or equivalence element must be subordinate to category of the present utility model such as.
