In the present invention, by improving the structure that allows the operator to open the tip portion of the shear blade 10 of the red, scissors (2) and to retract the hand to be convenient to at least two of the maximum opening angle of the tip of the shear blade (10) It is implemented to form a step.

Red fruit scissors 2 according to an embodiment of the present invention has a known configuration in which the shear blade 10 is positioned at the front and the spring 16 is interposed between the one handle 12 and the other handle 14.

According to an embodiment of the present invention, one side and the other handle 12 and 14 are made of a resin material such as synthetic resin. The rear end portion of one of the handle 12 is formed with two connecting shaft holes (45, 46), one connecting shaft hole (45) is inserted into the ring-shaped hook ring 18 for narrow opening formed by bending the wire The other connecting shaft hole 46 is inserted into the ring-shaped hook ring 44 for the flexible heavy opening made of a resin material to be connected to the shaft. In addition, inside the rear portion of the other handle 14, the operation ring portion 20 having an internal working space of the triangular composition is integrally formed.

Among the two ring-shaped hooks 18 and 44, the ring-shaped hook 18 for narrow opening has a maximum opening angle of the tip of the shear blade 10 of the red scissors when it is fitted to the working ring 20. As shown in FIG. 2, the opening of the ring-shaped locking ring 44 for the medium width opening is the maximum opening angle of the tip of the shear blade 10 of the red and scissors 2 when it is fitted to the working ring 20. As in the middle, such as to open. Therefore, when the worker selectively hangs one of the ring-shaped hooks 18 and 44 on the working ring 20, the worker can cut the enemy and the like at the desired cutting edge.

In the present invention, the operation ring portion 20 formed integrally with the other handle 14 has a support piece 24 extending downward from the inner side of the other handle 14 and the free finger end 22a at one end thereof. It consists of a ring body 22, the other end of the ring body 22 is integrally connected to the lower portion of the other handle 14 and one end of the support piece 24 to the free end 22a of the ring body 22 In contact with the other end of the support piece 24 is formed integrally connected to the other handle 14 of the upper ring body (22). As the operation ring portion 20 formed at the rear end of the other handle 14, a narrow locking ring locking ring 18 or a heavy locking ring locking ring 44 is selectively fitted and a ring locking in the inner working space thereof. One of the rings 18, 44 causes limited operation.

In configuring the operation ring portion 20, the free finger end 22a of the ring body 22 is provided with a limited operating space of the ring-shaped locking ring 18 for narrow openings or the ring-shaped locking ring 44 for heavy openings. , Is bent upward from the lower ring body 22 protruding toward the opposite handle 12 and slightly inclined toward the other handle 14, and the upper support piece 24 is in the rear portion of the other handle 14. It is formed to extend inclined from the side to the side downward. At this time, the free edge 22a of the ring body 22 of the lower portion and the one end of the support piece 24 of the upper portion of the ring body 22 are folded and contacted to provide an access path at the ends of the ring-shaped hooks 18 and 44. Furthermore, the outer surface of the free finger tip 22a is configured to be in surface contact with the inner surface of one end of the support piece 24.

One end of the support piece 24 is stepped with a locking step 24a so that the edge of the narrow ring-shaped hooking ring 18 for narrow opening does not need to be unnecessarily caught on its inner surface even when the free edges 22a and the support piece 24 are stacked. ) And the outer surface of the free finger end 22a of the ring body 22 is in contact with the inner surface of the locking jaw 24a of the support piece 24 in a state where a sliding surface is formed on the stepped side of the locking jaw 24a. Form a structure.

By the structure of the operation ring portion 20 as described above of the ring-shaped hook ring 18 for narrow openings or the ring-shaped hook ring 44 for heavy openings axially connected to the connecting shaft hole 45, 46 of one handle 12 The end is allowed to enter and exit between the inner surface engaging jaw 24a of the support piece 24 of the operating ring portion 20 and the free finger tip 22a. When one of the ring-shaped locking ring (18) (44) enters the inner working space of the operating ring portion 20, while hitting the outer jaw of the locking jaw (24a) of the support piece 24, the freedom of the ring body 22 When the end 22a is pushed in and the ring-shaped catching rings 18 and 44 are pulled out from the inner working space of the operating ring portion 20, the stepped locking jaw 24a is attached to the end of the support piece 24. Push out.

Ring opening ring 18 for narrow opening is bent into a square ring shape for smooth entry and exit into the operation ring portion 20 and the internal operation space of the operation ring portion 20 and one end of the square ring is downward It is preferable to be curved.

Ring-shaped locking ring 44 for the medium width opening is made of a resin material and flexible, but it is preferable not to stretch or fall out of the connecting shaft hole 46. Therefore, it is preferable that the medium widening ring-shaped engaging ring 44 has a closed ring shape and has a diameter of 3 to 6 times thicker than the small widening ring-shaped locking ring 18 made of iron wire.

Producing the ring-shaped locking ring 44 for the heavy width opening in the form of a closed ring is also possible by joining both ends of the resin string by ultrasonic welding or the like, but it is expensive and the tensile strength may be weakened. It is preferable to produce with. Therefore, the incision line 48 from the outer back surface of the one-side handle 12 to which the tension force is not applied to fit in the connection shaft hole 46 formed at the rear end of the one-side handle 12 of the red-ear scissors 2 is connected to the connection shaft hole 46. Forming, it is preferable to fit the ring-shaped locking ring 44 for the heavy opening in the connecting shaft hole 46 of the one-side handle 12 through the incision line 48.

In addition, it is preferable that the medium widening ring-shaped locking ring 44 has a length of 1.2 to 1.7 times as compared with the length of the small opening ring-shaped locking ring 18.

In the accompanying drawings, reference numeral "40", which is not described, is a parking groove line to hold the ring-shaped hook 18 when using the scissors 10 of the red scissors 2 greatly, and reference number 42 is red scissors (2) is a parking groove line to tie one side and the other handle 12, 14 with a ring-shaped hook 18 when not in use.

On the other hand, if the worker wants to limit the operation of the tip of the shear blade (10) so that the narrow opening of the scissors, and then insert the ring opening hook 18 for narrow opening to the operation ring part 20, at this time The ring-shaped catching ring 44 does not interfere with the operation even if left behind.

If the worker wants to limit the operation of the tip of the scissors 10 of the red and scissors 2 to be a heavy opening, the ring-shaped locking ring 44 for the heavy opening can be inserted into the operation ring 20. In this case, it is enough to hang on the parking groove line 40 formed on one side handle 12 of the red scissors.

In addition, when the shear blade 10 of the red and scissors (2) to be wide open operation, the heavy open ring-type locking ring 44 is removed from the working ring part (20).

When the ring-shaped locking rings 18 and 44 enter and exit the operating ring portion 20, the user grasps the ends of the ring-shaped locking rings 18 and the free finger end 22a and the support piece 24 of the ring body 22. The ring-shaped locking rings 18 and 44 are guided in and out more easily, and the ring-shaped locking rings 18 and 44 enter the operating space of the operating ring unit 20 to perform limited operation. In this case, as shown in FIGS. 2, 3, and 5 and 6, the end portions of the ring-shaped catching rings 18 and 44 come and go on the inner bottom surface of the ring body 22 and the inner column surface of the other handle 14. Will be

In order to allow the ring-shaped locking ring (18) (44) to travel easily on the inner bottom surface of the ring body (22) and the inner column surface of the other handle (14) in the inner working space of the operating ring portion (20). , The ring body 22 located on the other handle 14 is formed relatively higher than the connection shaft hole 45, 46 position of the ring-shaped hook ring 18, 44 of one handle 12 and the ring An inclined surface 30 is formed on the inner surface of the connection portion between the main body 22 and the other handle 14.

This configuration is such that the end of one of the ring-type hooks 18 and 44 that enters the inner working space of the operating ring 20 when the user holding the red scissors 2 is not used to grip the spring 16. By the reaction force, the bent starting point of the free edge 22a in the ring body 22 is caught, and the state at this time is that the tip of the shear blade 10 is in the state of small open or heavy open. 2 and 5.

When the user holding the enemy scissors (2) to use the grip force, the end of the ring-shaped hook ring (18) (44) rides on the inner bottom surface of the ring body 22, climbs up the inclined surface (30), and then the other handle (14) Ride up to the starting point of the upper support piece 24 while riding on the inner column surface. Such a state is a state in which the shear blade 10 of the red fruit scissors 2 is closed and completely overlapped as shown in FIGS. 3 and 6.

In the case of ring-type hook ring (18) (44) of the heavy-width ring ring hook ring (44) is operated by hooking the operation ring portion 20, the heavy-width ring ring hook ring (44), although the ring-shaped hook ring for narrow opening ( Compared with 18), the length is relatively long, but because it is flexible, it is bent after being raised to the upper point of the operation ring part 20, so there is no problem in completely overlapping the shear blades 10.

When the user releases the grip in the fully overlapped state of the blade 10 as shown in Figs. 3 and 6, one handle 12 and the other handle 14 are opened by the elastic force of the spring 16 and the ring-shaped hook ( The end of 18) (44) is lowered in the reverse order of the upward movement in the inner working space of the operating ring portion 20 to be in the state as shown in FIG.

When the user quickly operates the red scissors 2, the ring-shaped hooks 18 and 44 can deviate from the traveling path in the inner working space of the working ring 20, but the support piece 24 and the ring in which the access path is located. Since the inner surface of the free finger end 22a of the main body 22 forms a flat plane with the sliding surface, there is little fear that the end portions of the ring-shaped engaging rings 18 and 44 may unexpectedly escape to the outside.

Scissors (10) of the scissors and scissors (2) is often grind to the grindstone in order to hear well, so when not in use should be well tied to minimize the risk of accidents.

8 shows a state in which the worker has tied the red and scissors 2 by using the narrow-opening ring-type locking ring 18 after the work is completed, and the ring-shaped locking ring 44 for the heavy-width opening is flexible so that the operating ring part (20) by inserting the ring-shaped hook ring 18 for narrow opening to the parking groove line 42 by tying one side and the other handles 12 and 14 of the red scissors 2 10) to be safe.
