Description of the invention (1) [Industrial application field] The present invention relates to a pair of scissors members each having a receiving blade and a cutting blade that are bent in the same direction, and are pivotally supported by a supporting shaft for free rotation. A person who cuts thick branches, or cuts fruit trees, roses, etc. using cutting scissors [previous technique] Usually, cutting scissors use a protruding spur on the support shaft of the scissors member that receives the edge, and insert it into the The round or arc-shaped through-holes of the cutting edge edge scissors members enable the pair of scissors members to freely rotate with each other to be pivoted. However, in the previous cutting scissors, the blade angle of the receiving blade is shown in Fig. 5, and a certain angle 0 is often formed along the blade line from the state of the base (a) to the state of the tip (c). [Problems to be solved by the invention] Printed by the β-Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions before writing this page) (However, in such a case, the blade must be larger When cutting the to-be-cut object, the cutting edge corresponding to the to-be-cut object has a relatively large edge angle, so the cutting edge does not easily invade the to-be-cut object, and a large amount of effort is required to cut, At the same time, the positioning of the cut object is difficult, so the working efficiency will be significantly reduced. On the one hand, when the blade angle corresponding to the receiving edge of the cut object is set to a small blade angle that easily penetrates into the cut object, the receiving The front end of the blade will obviously become thin and thin, which may cause problems such as easy breakage. The purpose of the present invention is to provide scissors for cutting that eliminates this problem.

Description of the invention (2) 0 [Means to solve the problem] The scissors for cutting of the present invention are mainly pseudo, In separately A pair of scissors members 3, 4 having a receiving blade 1 and a cutting blade 2 bent in the same direction, and a shaft 5 is pivoted freely on the support shaft, and its special emblem is that the blade angle 0 of the receiving blade 1 follows from the base It gradually becomes larger toward the front end and changes smoothly. [Function] Therefore, when using the scissors for cutting according to the present invention, first, the branches of the fruit tree or rose to be cut are inserted into Between the receiving blade 1 and the cutting blade 2, then in this state, the receiving blade 1 and the cutting blade 2 are closed by the holding portions 6, 7 where the receiving blade 1 and the cutting blade 2 are integrated, and The cutting operation is performed. However, the portion of the receiving blade 1 facing the object to be cut at the start of cutting will have a small acute angle of 0 as shown in FIG. 3 (a), so it will be easy and deep. , The cutting blade 1 is invaded into the object to be cut, so that the positioning of the object to be cut is reliably performed. At the same time, the position of the receiving edge 1 relative to the object to be cut when the cutting starts The part where the object started to invade is very close to the support shaft 5, so it can be more effectively with less force, and it is indeed The intrusion function is exerted, and at the tip of the receiving blade, the blade angle becomes a large acute angle, so that the thickness of the blade tip portion becomes thicker, and it is possible to easily perform the cutting operation of twigs and the like without causing damage.

Description of the invention (3) [Effects of the invention] Since the scissors for cutting of the present invention have the above-mentioned structure and function, they can be freely carried out on thick branches, etc., as well as thin branches, and branches can be easily carried out At the same time, the thicker branches or hard branches can also easily complete the cutting operation without pain or obvious fatigue of the fingers, and because of the ability to make the front end of the receiving blade The thickness of the part becomes thicker while maintaining sufficient strength, so it will have an effect of greatly reducing the damage of this part. [Examples] Hereinafter, examples of the present invention will be specifically described based on the drawings. Figures 1 to 4 show the embodiment of the scissors for cutting according to the present invention. Figure 1 shows the closed state of the blade, while Figure 2 shows the front side of the blade in the largest state. Figure 3 shows the receiving blade.

These two members 3 and 4 are commonly used as cross The support shaft 5 can be pivotally opened and closed. That is, for the support shaft 5, you insert the support shaft 5 protruding on one side of the receiving blade 1 into the through hole (not shown) provided on the side of the cutting blade 2 to make the pair of scissors members 3 , 4, can be opened and closed freely after being supported, -------, -------, ----------- install ------ order- ----- Line (please read the note of Zunmian ^ item first, then fill out this page) _ f Printed by the R and Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy 297 mm) I. 5 — 204395 A6 B6 Printed by the Industrial and Commercial Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. V. Description of the invention (4) The screw is installed at the front end of the support shaft 5 by screwing the nut. In order to prevent rust and improve wear resistance, the aforementioned receiving blade 1 and cutting blade 2 are plated with hard chromium to harden the surface of the blade body. The cutting blade 2 can be formed as a small back blade that is cut into a triangular shape as previously known, as is known from the past, in an attempt to improve the cutting effect. A spring 9 is interposed between the aforementioned two members 3 and 4. Normally, if these two members are easily opened, they are opened. At the same time, a pair of stopper members 10 and 11 that are free to disengage each other are attached to the tail ends of the grips 6 and 7 respectively, so that when the two members 3 and 4 are closed against the aforementioned spring 9, the bending The ring-shaped stopper member 10 is inserted into the notched stopper member 11 which is engaged with the other, and is held in a state where the scissors shown in Fig. 1 are closed. The aforementioned receiving blade 1 is constituted by an angle formed by a gland with its sliding surface, that is, the blade angle gradually increases from the base to the front end and smoothly changes. In more detail, this state is as follows when detailed in FIG. 4. At the base of the receiving blade 1, as shown in the same figure (a) 0, it is made into a sharp blade angle (about 30 °) that is easy to invade the object 13 to be cut. At the middle of the receiving blade 1, As shown in figure (b), it becomes a blade with an acute angle of approximately moderate degree Θ2 (about 45 °), which is gradually changed from the aforementioned base to the front end to form a large blade angle, and at the same time, it is changed from the blade tip The formed curve is formed with a curve that does not produce extremely smooth sections. Then, if necessary, a notch 12 may be provided as shown by a two-dot chain line in Fig. 3 so that the positioning energy can be confirmed.

DESCRIPTION OF THE INVENTION (5) At the same time, at the front end of the receiving blade 1, as shown in the same figure (C), it becomes a blade angle 03 (about 60 °) with a blunt angle. Therefore, those whose ends are tapered before the usual receiving blade are likely to be damaged due to insufficient strength, but in the present invention, sufficient strength can be maintained. (The above brackets are shown in the blade angle of this embodiment.) Furthermore, in this embodiment, the base of the receiving blade 1 which has a particularly large intrusive force is formed to have a large size like the blade, so the large diameter is The cut will also be able to cut. At the same time, it is also possible to increase the degree of sharpness of the blade angle by using the metal with high hardness such as high-speed copper as the original material of the receiving blade 1 and the cutting blade 2.
