Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pruning scissors having good workability and excellent sharpness.

[0002]

2. Description of the Related Art As pruning scissors, various ones are provided in large numbers according to the object and purpose of the pruning scissors, but in particular, ordinary general type scissors used for picking, picking flowers, defoliating and pruning. Basically, in any case, the blade part has a tapered shape with good sharpness so that the pruning work can be performed reliably even in a narrow place, and simply grips the handle part to open and close the blade part. The desired pruning operation can be easily performed by itself.

[0003]

However, although the conventional ordinary general type has the advantages of being small in size and being excellent in sharpness, in using it,
Since the blade must be opened and closed while always gripping the handle, depending on the object to be pruned and the purpose, there is a risk that the hand holding the handle will be a great obstacle or injured by the spines of trees. In addition to being sufficient, it was often found that the ideal pruning operation could not be performed due to this.
Further, it was impossible to perform pruning work out of reach.

Therefore, in such a case, it may be considered to use a long-handled type for high branches. Certainly, the long-handled type does not have the risk of getting in your hands or getting injured, and it is also possible to work well where it is out of reach, but pruning a rather thick branch Due to the intended relationship, the blade part is also relatively large, which is not suitable for the fine pruning work as described above, and the sharpness is not as good as that of the general type, so again, also for that purpose I have to say that there is a great deal of difficulty.

[0005]

SUMMARY OF THE INVENTION The present invention was developed in view of such circumstances, and a blade portion is provided on one end side of a long handle and a handle portion is provided on the other end side thereof, and the handle portion and the blade portion are provided. Assuming pruning scissors that connect the and with a wire and open and close the blade by operating the handle, the blade is composed of a pair of symmetrically tapered blades, while a guide is attached to one end of the long handle. A support piece having a long hole is fixed, and the pair of blades is rotatably supported on the support piece, and the base end of each blade and the tip of the wire are connected by a pair of links. A structure is adopted in which a pin member that connects the overlapping end portions of the respective links and the distal end portion of the wire is connected and moved back and forth within the guide elongated hole of the support piece.

[0006]

Therefore, in the present invention, since the blade portion can be opened and closed by operating the handle portions separated by the long handle, there is no need to worry about the hand being hindered or injured during the pruning work, and the blade can be removed. The part is composed of a pair of symmetrically tapered blades, and the pair of blades is surely opened and closed by the action of the link and the pin member that moves back and forth in the guide elongated hole. Therefore, it is possible to sufficiently deal with the fine pruning work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an illustrated embodiment. The pruning scissors according to the embodiment, as shown in FIG. A blade portion 2 is provided on one end 1a side of the long handle 1 and a handle portion 3 is provided on the other end 1b side thereof, and the handle portion 3 and the blade portion 2 are connected by a wire 4 to connect the blade portion 2 to the handle portion 3 Although it is premised on a structure that can be opened and closed by the operation of, the feature is that the following configuration is adopted.

That is, in the present embodiment, as shown in the drawing, the blade portion 2 is composed of a pair of blade bodies 2A and 2B which are symmetrical and have a tapered shape with excellent sharpness.
A support piece 5 having a long guide hole 5a is fixedly provided on one end 1a side of the blade, and the pair of blades 2A.
B is pivotally supported by a pivot 6 so that it can be opened and closed, and the base ends of the blades 2A and 2B and the tip 4 of the wire 4 are supported.
a and a pair of links 8A and 8B through the pivot 7 and 7.
And the pin member 9 connecting the overlapping end of each of the links 8A and 8B and the tip 4a of the wire 4 is moved back and forth along the guide elongated hole 5a of the support piece 5. . In the figure, 10 is a lock lever of the handle portion 3, and 11 is a fixing pin for fixing the support piece 5 to the long handle 1 side.

Therefore, when the pruning scissors having such a structure are used, the handle portion 3 thereof is operated to retract the pin member 9 in the elongated guide hole 5a to obtain a sure guide state thereof. Connect the tip 4a of the wire 4 to the pair of links 8A.
When retracted together with 8B, the pair of blades 2A and 2B are synchronously and completely closed by the pulling action of the links 8A and 8B, on the contrary, the spring pressure of the handle portion 3 is received. By the reverse operation, while the pin member 9 is advanced in the guide elongated hole 5a, a reliable guide state is obtained and the wire 4
When the front end portion 4a of the link 8A is pulled out together with the pair of links 8A and 8B, as shown in FIG.
The pair of blade bodies 2A and 2B are completely opened in synchronization with each other by the pushing action of No. 2, so that the pruning work can be performed by repeating such an operation.

Moreover, in pruning work, since it is sufficient to grasp the handle portion 3 and perform the operation thereof, unlike the conventional ordinary general type, the hand is obstructed or injured during the work. It goes without saying that there is no need to worry, but the presence of the long handle 1 makes it possible to deal with narrow and hard-to-reach places, so it is rather difficult until now. The pruning work that is performed can be performed very easily, and ideal pruning work suitable for the purpose can be guaranteed.

Moreover, under the present embodiment, as described above, the blade portion 2 is constituted by a pair of blade bodies 2A and 2B having a symmetrical tapered shape, and the pair of blade bodies 2A and 2B is formed. Since the links 8A and 8B and the pin member 9 that moves back and forth in the elongated guide holes 5a open and close in synchronization, there is a great advantage that it is possible to sufficiently cope with fine pruning work that requires particularly sharpness.

In the above embodiment, the long handle 1 is provided with a desired dimension in consideration of weight reduction and cost.
Although the present invention uses a round pipe material, the present invention is not limited to this. For example, two inner and outer pipe materials are used, and the present invention has already been proposed by the applicant. It is also possible to use the expandable structure disclosed in Kaihei 6-75126 to make it possible to freely change the length dimension of the long handle 1 itself as necessary.

Further, although not specifically shown, an auxiliary grip is movably fitted on the outer periphery of the long handle 1 so that work can be performed while gripping the auxiliary grip in addition to the handle portion 3. Alternatively, it may be configured as desired, or a shoulder belt may be additionally provided to facilitate the transportation and handling of the pruning scissors themselves, depending on the implementation.

[0014]

As described above, according to the present invention, by adopting the above-mentioned constitution, there is no fear of the hand being hindered or injured during pruning work, and fine pruning work in which sharpness is particularly required. Will be able to cope sufficiently. In addition, the presence of a long handle makes it possible to cope with narrow and hard-to-reach places and hard-to-reach places, so pruning work becomes easier and ideal pruning is possible compared to the past. The work can be guaranteed.
