Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to scissors in which a blade body and a scissors body are formed separately, and which has a structure in which the blade body is clamped and fixed. Traditionally, most scissors had a cutting edge formed directly on the blade, but in recent years,
Replaceable blade scissors with separate blades and blades are emerging. There were two types of replaceable blade scissors: one in which the blade was made into a sheath and placed over the blade, and the other in which the blade was used as a clamping part and the blade was inserted between them. Sheath-shaped spare blades have the drawbacks that it takes time and effort to manufacture the blades, and that the manufacturing costs of the blades are high.
On the other hand, the clip-on type replaceable blade has the advantage that the replaceable blade body can be manufactured easily and inexpensively, and the blade body can be mounted firmly and stably.

SUMMARY OF THE INVENTION An object of the present invention is to provide scissors in which a replaceable blade body can be easily inserted into the clamping plate by providing a step at the tip of the clamping plate of the blade.

Next, the structure of the present invention will be explained according to an embodiment shown in the drawings.

The scissors are formed by connecting two blade parts 1 and 2 with screws 3. In this invention, the finger hook is not necessary for the explanation and is therefore omitted from the drawings. The blade parts 1 and 2 each consist of two clamping plates 4 and 5 and a blade body 6. The outer clamping plates 5 are formed integrally with the handles 7 and 8, respectively, and the inner clamping plates 4 are joined to the clamping plates 5. Gap 9 between the inner clamping plate 4 and the outer clamping plate 5
The blade body 6 is inserted from the front.

Of the clamping plates 4 and 5, the tip of the outer clamping plate 5 is slightly more protruding than the tip of the inner clamping plate 4. When inserting the blade 6, the end of the blade 6 is placed against the inner end surface 18 of the outer clamping plate 5 to determine the position, and then inserted. Blade 6 inserted into the gap 9
is clamped and fixed from both sides by the elastic force of both clamping plates 4 and 5.

A slider 10 protrudes from the peaks of the blade parts 1 and 2, and the front end of the slider 10 is in contact with the rear end of the blade 6. By placing a finger on the finger rest 11 of the slider 10 and pushing it forward of the blade parts 1 and 2, the inserted blade body 6 projects in front of the clamping plates 4 and 5. The blade 6 can be pulled out by manually pulling the tip of the protruding blade 6.

The blade body 6 has a lower plate portion 1 extending from the blade edge 12 toward the upper edge.
3. It is bent and divided into a middle plate part 14 and an upper plate part 15. The reason why the lower plate part 13 and the upper plate part 15 are at different levels is to bring the blade edge 12 of one blade part 1 into contact with the blade edge 12 of the other blade part 2 to function as scissors. The upper plate part 15 and the middle plate part 14 of the blade body 6 are clamped and fixed between the clamping plates 4 and 5, and the lower plate part 13 and the blade edge 12 are connected to the lower plate part 13 and the blade edge 12 of the other blade body 6. Contact.

The reference numeral 16 in the figure is a spare blade supply device. A plurality of replaceable blade bodies 6 are stored one on top of the other in the replaceable blade supply device 16, and are pushed up from below by a leaf spring. By moving the push-out portion 17 forward, the uppermost blade body 6 is pushed out from the replaceable blade supply device 16. When inserting the blade body 6 between the clamping plates 4 and 5, a part of the blade body 6 protrudes from the replaceable blade supply device 16, and the protruding end of the blade body 6 is inserted into the outer clamping plate 5 of the scissors. Position the tip by placing it on the inner surface 18 of the blade supply device 16.
By moving the extrusion part 17 further forward, the blade body 6 can be inserted into the clamping plates 4 and 5.

If the ends of the clamping plates 4 and 5 are aligned, there is a drawback that when inserting the blade 6, the hand shakes, making it difficult to position it in the insertion slot.

This invention is a replaceable blade clamping type scissors having a structure in which the tip of one clamping plate 5 is slightly protruded from the tip of the other clamping plate 4. 4, 5, by simply applying the end of the blade 6 to the tip inner surface 18 of the protruding clamping plate 5, positioning for insertion can be easily done and insertion is easy. .
