Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to improvements in scissors such as cooking scissors.

(Prior art) There have been scissors that can separate the two main parts of the scissors, but because the two main parts come apart when the angle of the two main parts is widened, it is difficult to separate the two main parts during use. The problem was that it could come off.

(Problems to be solved by the invention) The present invention eliminates the drawback of the conventional product that when both the main bodies are widened, they separate and come off. The purpose is to provide scissors that do not lose their focus.

(Means for solving the problem) The configuration of the present invention includes a blade portion 3 in front of the handle portions 1 and 2.
The two main bodies 5 and 6 on which the blades 4 are provided are rotatably mounted around a support shaft 7, and the support shaft 7 is fixedly attached to one of the blade parts 3 and the support shaft 7 The part 11 and the overhanging head 8 protrude from the back surface of the blade part 3, and the shaft hole 9 into which the support shaft 7 can be inserted is inserted into the other blade part 4 only when the angle of both the main bodies 5 and 6 is greatly widened.
In normal use, the protruding head 8 of the spindle engages the edge of the shaft hole to connect the double-edged parts 3 and 4, and the shape of the shaft hole 9 is circular. An elongated hole 16 protrudes from a part of the circumference of the hole 10 in the shape of a keyhole, and is provided at the spindle body 11 of the spindle 7 and its end and extends in a direction perpendicular to the spindle body 11. An overhanging head 8 protrudes from the back surface of the blade 3, and the width of the cross-sectional shape of the spindle body 11 is slightly smaller than the width of the elongated hole 16, and its length is slightly smaller than the width of the elongated hole 16 inscribed in the circular hole 10. It has an elongated shape, and the overhanging head 8 extends in the longitudinal direction of the cross section of the spindle body, and its length is larger than the inner diameter of the circular hole 10 and is connected to the circular hole 10 and the elongated hole 1.
It is formed smaller than the combined length of 6,
When the protruding support shaft 7 is inserted into the shaft hole 9, the projecting head 8 protrudes from the shaft hole 9, and the support shaft body 11
is fitted in the shaft hole 9, and is characterized in that the shaft body 11 is rotatably inscribed in the circular hole 10 by pulling the other main body 6 in the direction of the handle 2.

Next, embodiments of the present invention will be described with reference to the drawings.

A support shaft 7 is fixedly attached to one of the blade parts 3. The spindle 7 has a head 8 extending from above, a spindle body 11 below it, a spindle base 12 below it, and a threaded portion 13 below it, which are integrally formed in this order. Among these, the threaded portion 13 passes through a bearing hole drilled in one of the blade portions 3 and projects onto the surface of the blade portion 3.
The spindle base 12 is fitted into a bearing hole bored in the blade part 3. The spindle body 11 and the overhanging head 8 protrude from the back surface of the blade 3. A nut 15 is screwed onto the threaded portion 13 via a washer 14.
A step is formed at the boundary between the spindle base 12 and the spindle body 11, and this step engages with the back surface of the blade 3, allowing the spindle 7 to be fixed with the nut 15.

The shaft hole 9 is continuous with the circular hole part 10 and the shaft part 2 is connected to the circular hole part 10.
An elongated hole 16 is bored on the side.

(Operations and Effects) The present invention has the above-mentioned configuration, and since the length of the projecting head 8 is smaller than the combined length of the circular hole 10 and the elongated hole 16, the angle between the two main bodies 1 and 2 is When widened widely and the length direction of the shaft hole 9 and the length direction of the overhanging head 8 are aligned, the support shaft 7 aligns with the shaft hole 9.
The projecting head 8 is inserted into the shaft hole 9, and the projecting head 8 protrudes from the shaft hole 9, and the support shaft body 11 is accommodated in the shaft hole 9. When the other main body 6 is then pulled rearward, the spindle body 11 moves into the circular hole 10 and becomes inscribed therein. Therefore, in this state, when both main bodies 1 and 2 are closed, the spindle body 11
is inscribed in the circular hole 10 and can rotate the main body 2. In this case, since the projecting head 8 is engaged with the edge of the circular hole 10, the two main bodies 5 and 6 will not come off.

The feature of the present invention is that even if the angles of the main bodies 1 and 2 are wide open during use and the directions of the overhanging head 8 and the shaft hole 9 are aligned, one of the overhanging heads will remain closed as shown in FIG. Since the end portion 17 is locked to the edge of the circular hole portion 10, there is no risk of the two main bodies coming off unexpectedly.

Claims (1)

[Scope of utility model registration request] Two main bodies 5 and 6, each having blade parts 3 and 4 provided in front of the handle parts 1 and 2, are pivoted so as to be rotatable around a support shaft 7, and the support shaft 7 is attached to one of the blade parts. 3, the shaft body 11 and the overhanging head 8 protrude from the back surface of the blade part 3, and the shaft hole into which the shaft 7 can be inserted only when the angle of both main bodies 5, 6 is greatly widened. 9 is bored in the other blade part 4, and in normal use, the overhanging head 8 of the spindle locks on the edge of the shaft hole to connect the two blade parts 3 and 4.
