Abstract
The utility model discloses a branch is cut with adjustable length, including the scissors, a scissors handle is connected with the steel wire, and another handle is a telescopic link, installs the pressure spring between telescopic link and handle, the steel wire is walked around the pressure that assembly pulley on the telescopic link was connected to the telescopic link other end and is drawn on the device. Through the regulation of telescopic link to scissors extension length, adapt to the branch that the cutting range is different, be applicable to various high trees, reduced the labour, avoided artifical and pruned the danger that the eminence branch brought, and only one side handle extends, makes its influence of not receiving dense tree crown.
Description
Technical field
The utility model relates to agricultural tools field, particularly relates to planting tool field.
Background technology
Fruit tree is constantly pruned its branch in necessary for growth, in order to avoid branch is too many, cause the space in tree crown too narrow and small, the fruit in the process of growth of fruit in tree crown can be kept the sun off by intensive branch, affect the growth of fruit, affect the output of orchard worker.And when orchard worker is to branch pruning, the branch for eminence needs to climb the tree and could prune, in the beta pruning on the other hand of the hand steered tree of pruning process one, so not only greatly, operating efficiency is also very low for danger but also workload.And the existing scissors pruning eminence branch can only be pruned eminence branch, when pruning the branch be located in, needs are separately equipped with one the scissors cutting short branch, the inconvenience when carrying like this.
Utility model content
In order to solve the problems of the technologies described above, the utility model aims to provide a kind of tree shears of adjustable in length.
The utility model is achieved by following technical solution:
A tree shears for adjustable in length, comprises scissors, and scissors one handle is connected with steel wire, and another handle is an expansion link, is provided with stage clip between expansion link and handle, and the described steel wire assembly pulley walked around on expansion link is connected on the pressure drawing device of the expansion link other end.
Described expansion link is divided into the first bar, the second bar, bottom bar, and wherein the first bar is arranged in the second bar, and the second bar is arranged in bottom bar, and the first bar is provided with assembly pulley on top, handle one end, and bottom bar upper end is also provided with assembly pulley, and two assembly pulleys on the same line.
Described bottom bar has symmetrical aperture at assembly pulley lower position, and steel wire is connected with pressure drawing device through aperture.
Described pressure drawing device comprises the base be arranged on bottom bar, be provided with pulley by circular shaft in base, lever is equipped with in pulley both sides on circular shaft, and one end of lever is provided with hinge axis, one end protuberate basic unit of described circular shaft is also hinged with a square pole, and square pole is inlayed and is arranged in the groove of base.
The beneficial effects of the utility model are:
Compared with prior art, the tree shears of a kind of adjustable in length that the utility model provides, by the adjustment of expansion link to scissors development length, adapt to the branch that cutting range is different, be applicable to various height trees, decrease labour, avoid manually in the danger that pruning eminence branch brings, and only have handle on one side to extend, make it not receive the impact of dense tree crown.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is pressure drawing device structure chart of the present utility model.
In figure: 1-scissors, 2-handle, 3-stage clip, 4-expansion link, 5-second bar, 6-bottom bar, 7-presses drawing device, 701-circular shaft, 702-square groove, 703-square pole, 704-pulley, 705-base, 706-lever, 8-assembly pulley, 9-steel wire.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in the figure, the tree shears of a kind of adjustable in length that the utility model provides, comprise scissors 1, scissors 1 one handle 2 is connected with steel wire 9, another handle is an expansion link 4, be provided with stage clip 3 between expansion link 4 and handle 2, described steel wire 9 assembly pulley 8 walked around on expansion link 4 is connected on the pressure drawing device 7 of expansion link 4 other end.Carried out the length of adjusting device by the telescope features of expansion link 4, make device can be applicable to the branch pruning of differing heights.
Larger displacement can be obtained when pruning trees to make scissors, described expansion link 4 is divided into the first bar 10, second bar 5, bottom bar 6, wherein the first bar 10 is arranged in the second bar 5, second bar 5 is arranged in bottom bar 6, first bar 10 is provided with assembly pulley 8 on top, handle 2 one end, and bottom bar 6 upper end is also provided with assembly pulley 8, and two assembly pulleys on the same line.Described bottom bar 6 has symmetrical aperture at assembly pulley lower position, and steel wire is connected with pressure drawing device 7 through aperture.
In order to adjust the length of steel wire 9 faster and more easily when contraction pole 4 shrinks.Described pressure drawing device 7 comprises the base 705 be arranged on bottom bar 6, by circular shaft 701, pulley 704 is installed in base 705, lever 706 is equipped with in pulley 704 both sides on circular shaft, one end of lever 706 is provided with hinge axis 707, one end protuberate basic unit 705 of described circular shaft 701 is also hinged with a square pole 703, and square pole 703 is inlayed and is arranged in the square groove 702 of base 705.
In use, when pruning the branch of eminence, first allow itself and base 705 at an angle square pole 703 pull-up, then expansion link 4 is elongated to desired height, steel wire 9 is expanded to certain length automatically with the elongation of expansion link 4 on pulley 704, buckle square pole 703 make its pin steel pulley 704 allow its not rotation, then the position of scissors 1 is adjusted to the branch that will prune, pressure lever 706 makes it pull steel wire 9 to be with fixed handle 2 that scissors 1 is closed, cut branch, after cutting, by stage clip 3, scissors 1 is opened reset.When pruning the branch at short place, 4 bars that will stretch are regained, then square pole 703 is buckled to base 705 at an angle after, rotate square pole 703 and pulley 704 rotated after winding steel wire 9 makes it be contracted to certain length scissors just can be used to prune the branch at short place.
