Description
Technical field
The utility model relates to a kind of orchard shears, the orchard shears that particularly a kind of sectional is sheared.
Background technology
Orchard shears is a kind of cutting implement of pruning the plant branch.Traditional orchard shears can once be cut off when shearing the soft branch of quality; Yet,, need or repeatedly repeat to prune and just can cut off through twice sometimes because the application of force is not enough and the shearing resistance effect of thick and stiff limb for the pruning of more thick and stiff limb; Repeatedly can produce the phenomenon that to cut off limb in same sheared edge in the shear history; Therefore existing orchard shears exist in must loose one's grip again when shearing open that scissors pushes away forward and aim at the drawback of former sheared edge again, simultaneously, traditional orchard shears receives himself effect on structure; Twice or repeatedly to repeat to prune employed power be the same basically; Therefore, traditional orchard shears does not have the labour-saving effect when shearing thick and stiff limb, and the applicant has developed the orchard shears of a kind of sectional shearing and the laborsaving effect of tool for this reason.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides the orchard shears of a kind of sectional shearing and the laborsaving effect of tool.
The utility model solves the technical scheme that its technical problem adopted:
The orchard shears that a kind of sectional is sheared; Comprise first cut part and second cut part and first handle and second handle; It is characterized in that said first cut part and second cut part articulate through first pivot, the end of first handle articulates through second pivot and second cut part, and an end of first cut part is provided with at least two and shears gear; Be pivoted with a connecting rod in the first handle; One end of connecting rod connects with corresponding shearing gear through loose pin, and the other end of connecting rod and first handle are provided with shears gear switching mechanism, is provided with back-moving spring between connecting rod and the first handle.
As the utility model preferred embodiment; Comprise the location recess that is arranged on interlinking lever end, be arranged in the first handle and can locate that recess combines with this or the reference column that separates and be separately positioned on the first handle both sides and two drive blocks synchronization action that said reference column is arranged on wherein on the drive block but shear gear switching mechanism.
The drive block fixing body is installed on the said first handle, and the drive block fixing body is provided with two drive block installing holes, and said two drive blocks are installed in the corresponding drive block installing hole and can in the drive block installing hole, move.
As the improvement of the above-mentioned embodiment of the utility model, wherein, the both sides of at least one drive block are provided with the elasticity wedge that cooperates with drive block installing hole sidewall.
Above-mentioned second cut part is the shearing chopping block that is formed by the end extension of second handle.
Further improvement as the above-mentioned embodiment of the utility model is equipped with torsion spring on second pivot.
Above-mentioned shearing gear can be set to three.
The beneficial effect of the utility model is: the end of the first handle of the utility model articulates through second pivot and second cut part; One end of first cut part is provided with at least two and shears gear; Be pivoted with a connecting rod in the first handle; One end of connecting rod connects with corresponding shearings gear through loose pin, and the other end of connecting rod and first handle are provided with the switching mechanism of shearing gear, when the soft branch of shearing quality, through the switching mechanism of shearing gear the loose pin of connecting rod one end is cooperated with the gear of the top and can once cut off this branch; When shearing more thick and stiff limb; At first cooperates with bottom gear through shearing loose pin that gear switching mechanism makes connecting rod one end, the loose pin of accomplishing shear action back link one end is transformed into next gear automatically, can carry out second section shearing at this moment; Through twice or repeatedly shear action can branch be cut off; Because the other end that each shear action is accomplished back link just proceeds to a gear, thereby has changed the moment of orchard shears, reaches the labour-saving effect.

Embodiment
With reference to Fig. 1, Fig. 2; The orchard shears that the disclosed a kind of sectional of the utility model is sheared comprises first cut part 1 and second cut part 2 and first handle 3 and second handle 4, wherein; First cut part 1 and second cut part 2 articulate through first pivot 5; The end of first handle 3 articulates through second pivot 6 and second cut part 2, on second pivot 6 torsion spring 7 is installed, and can realize opening automatically of orchard shears through this torsion spring 7.In embodiment as shown in the figure, second cut part 2 is the shearing chopping blocks that formed by the end extension of second handle 4.
Like Fig. 2, shown in Figure 4, an end of first cut part 1 is provided with three and shears gear 8, is pivoted with a connecting rod 10 through the 3rd pivot 9 in the first handle 3; One end of this connecting rod 10 is provided with a loose pin 11, and this loose pin 11 can be fastened on three respectively and shear in the gear 8, thereby connecting rod 10 is connected with corresponding shearing gear 8 through this loose pin 11; The other end of connecting rod 10 and first handle 3 are provided with shears gear switching mechanism; And be provided with the back-moving spring 12 that connecting rod is resetted between connecting rod 10 and the first handle 3, can adjust the initial gear that cooperates with loose pin when shearing beginning, when shearing the soft branch of quality, the loose pin of connecting rod one end is cooperated with the gear of the top and can once cut off this branch through the switching mechanism of shearing gear through this shearing gear switching mechanism; When shearing more thick and stiff limb; At first cooperates with bottom gear through shearing loose pin that gear switching mechanism makes connecting rod one end, the loose pin of accomplishing shear action back link one end is transformed into next gear automatically, can carry out second section shearing at this moment; So repeatedly; For this embodiment, can branch be cut off through three shear action, because the other end that each shear action is accomplished back link just proceeds to a gear; To change the moment of orchard shears, reach the labour-saving effect.
