Description

  The present invention relates to a scissors with a cut branch gripping device that can grip a cut branch regardless of the cut branch diameter size.

Among the pruning shears, a high pruning shear that can cut off a branch at a high place without using a stepladder or a pruning ladder is widely used in practice as a pruning or mowing instrument.
However, because of the functional structure as a cutting trough, it was impossible to grasp and collect the cut branch at the same time as cutting.

As an improvement measure, in order to enable the harvesting of high branches and the harvesting of fruit branches, it is devised so that the branches are harvested at the same time as they are cut, and the branches are harvested without being dropped. Recently, an attachment for a high branch cutting paddle has been put into practical use.
This attachment is fixedly attached to one side of each of the upper and lower blades of the scissors or as a blade cover without interfering with the cutting function of the scissors within a certain range of branch diameter dimensions, so that the branches to be cut simultaneously with cutting. The attachment is pinched and grasped, and the state can be maintained and collected.

However, since these attachments are both fixed to the upper and lower blades of the scissors by mounting, the branch diameters that can be cut and grasped are limited to a predetermined size in advance, and the cutable dimension range of the scissors themselves is limited. For this reason, there are many disadvantages in that the branch diameter outside the cuttable range is unreasonable from the viewpoint of structure, and, for example, cutting cannot be performed simply by making a cut.

  The problem to be solved is that, in the means for grasping and collecting the cut branches simultaneously with the cutting of the branches, in the attachment of the fixed specification used for grasping the cut branches, the cutting function of the scissors itself is only within a certain range of the branch diameter. It is a point which cannot respond | correspond to all the unspecified branch diameter dimensions in the cuttable range which the heel itself has.

  The present invention relates to a cut branch gripping device in which a cutting edge gripping device that enables gripping of a cut branch at the same time as cutting even at an unspecified branch diameter size is attached to the blade portion of the scissors within the cuttable range of the scissors themselves. A scissor-branching device, wherein a cutting edge gripping device has a pin that fixes the tip portion of the scissors at the top edge of the scissors toward the cutting edge, and a holding plate that can be rotated only on the outside of the blade on the other side. Combining with the holding plate, the fixed plate fixed to the lower blade to enable gripping of the cut branch, and a coil spring is formed with the fulcrum pin of the collar as the central axis, and the end of the winding is the portion near the fulcrum of the upper blade The other end of the winding is hooked to the movable side end of the presser plate, so that the presser plate that can be operated in a freely adaptable manner to the unspecified branch diameter via the fixed plate fixedly attached to the lower blade. Required for the pivotable end The most important feature that the spring device constituting the presser spring force, was functional configuration.

  The scissors with a cut branch gripping device of the present invention can grip the cut branch regardless of the diameter of the branch, so that the center axis is a pin that fixes the position of one tip portion near the tip of the scissors with the upper blade of the scissors. Necessary in order to cope with unspecified branch diameters of the branches to be cut through a fixing plate fixedly attached to the lower blade of the heel to a holding plate that allows the other end side to be rotated only to the outside of the blade The pressing spring force is applied regardless of the branch diameter of the cut branch under various conditions when using the branch cutting of the scissors, and the rotation end of the pressing plate is connected to the required pressing force via the fixed plate. Therefore, there is a great advantage that it can be held near the blade edge and can be easily cut, and the cutting permissible function of the scissors can be maximized.

  A holding plate that performs a predetermined operation corresponding to an unspecified branch diameter via a fixed plate fixedly attached to the lower blade for the purpose of making it possible to grasp the cut branch regardless of the branch diameter size in the branch cutting and collecting work The minimum number of parts, such as a spring device that applies a pressing force required for the operation of the pressing plate, is realized without interfering with the function in the cutable dimension range of the ridge.

  1 is an overall perspective view, FIG. 2 is a right side view of FIG. 1, FIG. 3 is an explanatory view showing the state of use of FIG. 2, and FIG. 4 is a side view of the opposite side of FIG. It is.

Since the subject of the present invention is the mounting method of the unspecified branch diameter cutting and branching gripper system in the cocoon, description of the functional mechanism system in the pruning cocoon, the cutting cocoon, the pruning cocoon, etc. is omitted.
Hereinafter, it will be described in detail with reference to the drawings.

On the outer side surface of the lower blade 5 of the heel, the same thickness dimension is used to hold the cut-off branch 9 combined with the fixed plate 1 having a slight thickness dimension along the blade portion and fixedly mounted by the heel 1 '. The presser plate 2 having the above is provided on the outer side surface of the upper blade 4 without hindering the cutting function as a ridge.
In use, the faces of the fixed plate 1 and the pressing plate 2 facing each other are processed into rough jagged shapes in order to ensure the grasping of the cut branches 9.

The holding plate 2 provided on the outer side surface of the upper blade 4 has a structure in which one tip portion is fixed by a pin 2 'at a position where a slightly sized blade portion is left at the tip portion of the upper blade 4 and is rotatable. Thus, the other end side portion of the pressing plate 2 can be rotated only outside the upper blade 4 with the pin 2 'as the central axis.
At that time, a notch portion 2 ″ is formed in the lower end side portion on the upper blade 4 side on the rotatable end portion side of the presser plate 2, and the stopper plate 4 provided with a slight height on the side surfaces of the upper blade 4 facing each other. , The clockwise rotation in the rotation is stopped at that position only on the outer side of the upper blade 4 with the pin 2 'on the pivotable end side of the holding plate 2 as the central axis. Although the rotatable end of the pressing plate 2 can be rotated counterclockwise only to the outside of the upper blade 4, the upper blade 4 has a predetermined size so that the cutting function is not hindered. The part is made to be secured.

A fixed plate 1 in which one end portion side of the pressing plate 2 that can be rotated only to the outside of the upper blade 4 via a pin 2 'serving as a central axis is fixedly attached to the lower blade 5 when the scissors are used. In response to various conditions of the diameter of the cut branch through the pin 2, the pin 2 ′ is rotated counterclockwise outside the upper blade 4 around the center axis, and the cut branch 9 is sandwiched between the fixed plate 1 and can be gripped. A spring device comprising a coil spring 6 that constitutes a holding spring force required for applying a pressing force to the holding plate 2 is provided.
The coil spring 6 of the spring device is located on the opposite side of the upper blade 4 to which the holding plate 2 is attached, and the upper blade 4 without damaging the spring mechanism with the fulcrum pin 7 between the upper blade 4 and the lower blade 5 as the central axis. Is attached to the side face of the blade to prevent deviation, and one end of the winding end is hooked on the stopper plate 8 provided near the fulcrum pin 7 of the upper blade 4 on the same side as the coil spring 6 and fixed without falling off. Further, the other side is placed in the notch 3 having a slightly longer dimension formed in the same manner as the notch 3 formed in the peak portion of the upper blade 4 at the upper part of the pivotable end of the holding plate 2. The cutting end where the holding end of the winding end of the coil spring 6 is interlocked with the operation on the side of the rotatable end corresponding to various conditions of the cutting branch diameter via the fixed plate 1 and hanging through the side surface of the blade 4. The spring function is hindered from moving in the notch 3 In this way, the required operation on the side of the rotatable end of the holding plate 2 that operates in accordance with the unspecified branch diameter of the cut branch 9 in use is not impaired. A desired gripping force function in the cut branch 9 is made possible.

  Since such a cut-off branch gripper system mounting form is adopted, regardless of the cut-off branch diameter size, it corresponds to the non-specific branch diameter size within the range of the cutting function of the scissors, and the cut off of the non-specific branch diameter is performed. There is an effect that the branch can be grasped and the branch can be easily collected.

  In the cutting function range of the cocoon, it is possible to cut and grasp branches and collect them regardless of unspecified branch diameter dimensions. It can also be used for purposes such as collecting branches necessary for state observation.
