Description

A hair cutting scissors}

The present invention relates to a use scissors, and more particularly, to a use scissors that can minimize the damage and breakage of the blade due to the impact of contact with the ground even if the use scissors fall on the ground due to the user's circumference.

Generally, scissors are instruments used to cut something, and scissors are used for various purposes depending on their shape and shape. For example, scissors used to cut thin steel sheets, scissors used for pruning gardening, scissors used to cut fabrics of clothing, scissors used to cut paper, scissors used for medical purposes, and dishes used for cooking. It is divided into scissors, scissors used for use. The cutting force of the scissors depends greatly on the hardness of the blade, and the hardness depends on the conditions under which the blade is heat treated. In general, the hardness of the blade is heat-treated about 50-65HS, and recently, has been researched and developed in various ways to increase the cutting force of the scissors.

Although the hair can be cut to the desired place using the scissors configured as described above, such a scissors has a problem that the blade of the scissors is damaged and broken by the impact delivered when a predetermined shock is delivered to the scissors. In other words, if the scissors fall on the ground due to the user's circumference while cutting the hair using the scissors, the blades are often damaged due to the contact with the ground, and in severe cases, the blades are broken. there was.

Therefore, in view of the above-described problems of the present invention, the object of the present invention is to use scissors that can minimize the damage and breakage of the blades by the impact of contact with the ground even if the use scissors fall on the ground due to the user's sub-circumference In providing.

The formed handle 16 is provided. The first accommodating groove 18 is formed in the vertical direction at the central portion of the bottom surface of the first body 12, and the first coupling hole 19 is formed at the central portion of the first accommodating groove 18. Coupling groove 20 is formed in the vertical direction on one side of the upper surface of the first body (12). A second body 24 having a blade portion 22 formed on one side is provided, and a handle 28 having an insertion hole 26 through which a thumb is selectively inserted is provided on the other side of the second body 24. The second accommodating groove 29 is formed in the vertical direction in the center of the upper surface of the second body 24, and the second coupling hole 30 is formed in the central part of the second accommodating groove 29.

A torsion spring 34 in which the first elastic piece 32 protrudes in the horizontal direction is provided at the upper end, and the second elastic piece 36 protrudes in the horizontal direction at the lower end of the torsion spring 34. The first elastic piece 32 of the torsion spring 34 is inserted into the first accommodating groove 18 formed in the central portion of the bottom surface of the first body 12, and the second elastic piece 36 is the second body 24. It is inserted into the second accommodation groove (29) formed in the central portion of the upper surface. Torsion spring 34 is made of SUS304, it is preferable that the wire diameter is formed so that ø0.55, the center diameter is ø6.55, the inner diameter is ø6.0. A fastening screw 42 is provided which is fastened to the first coupling hole 19 of the first body 12 through the second coupling hole 30 of the second body 24. The outer diameter of the screw shaft 44 is preferably formed to be slightly smaller than the inner diameter of the first coupling hole 19 and the second coupling hole (30). A washer 52 having a coupling protrusion 50 inserted into and fixed to the coupling groove 20 formed on the upper surface of the first body 12 is provided at one side of the lower side, and provided with a stopper 52 on the upper surface of the washer 52. 54) are projected at equal intervals. Nuts 60 for fastening the fastening screws 42 to the coupling holes 19 and 30 of the bodies 12 and 24 are provided, and the upper surface of the washer 52 is provided at the lower end of the nut 60. A plurality of protrusions 62 contacting the stopper 54 protruding from each other are formed at equal intervals.

The state in which the use scissors configured as described above are combined and the effects thereof will be described.

First, the first elastic piece 32 of the torsion spring 34 is inserted into the first accommodation groove 18 of the first body 12, and the second elastic piece 36 is placed into the second accommodation groove of the second body 24. It is located at (29). The first elastic piece 32 of the torsion spring 34 is in the first receiving groove 18 of the first body 12 and the second elastic piece 36 is the second receiving groove 29 in the second body 24. When positioned in the), the coupling protrusion 50 protruding on the lower side of the washer 52 is inserted into the coupling groove 20 formed on the upper surface of the first body 12 and fixed. At this time, the coupling protrusion 50 of the washer 52 has a state of being fixed to the coupling groove 20 formed in the first body 12. When the coupling protrusion 50 of the washer 52 is fixed to the coupling groove 20 formed in the first body 12, the fastening screw 42 is coupled to the coupling holes 19 of the bodies 12 and 24, Insert in (30). At this time, the screw shaft 44 of the fastening screw 42 has a state protruding to the outside of the washer 52 through the coupling hole (19), (30).

When the screw shaft 44 of the fastening screw 42 protrudes out of the washer 52 through the coupling holes 19 and 30, the nut 60 is connected to the screw shaft 44 of the fastening screw 42. Fasten. At this time, the plurality of protrusions 62 protruding at equal intervals at the lower end of the nut 60 is in contact with the stopper 54 formed on the upper surface of the washer 52. When the first body 12, the torsion spring 34, and the second body 24 are rotatably fixed around the fastening screw due to the coupling of the fastening screw 42 and the nut 60, the scissors 80 ) Blades 10, 22 is to minimize damage and damage by the impact. That is, since the first body 12 and the second body 24 are in contact with each other by the torsion spring 34, a predetermined shock is transmitted from the outside or even when the user falls on the ground due to the user's subcircumference. 12), 24 and torsion spring 34 by absorbing the shock transmitted at the same time it is possible to minimize the damage and breakage of the blades 10, 22 of the use scissors 80 by the impact. In addition, the nut 60 is fastened to the screw shaft 44 of the fastening screw 42 in a state in which the protrusion 62 of the nut 60 is in contact with the stopper 54 protruding from the top of the washer 52. Even if the shock is transmitted to the fastening screw 42 and the nut 60 will not be separated.

As described above, since the use scissors according to the present invention are elastically supported to be in contact with the first body and the second body by torsion springs, the blade may be contacted with the ground even if the use scissors fall on the ground due to the user's sub-circumference. It is to have an effect that can minimize the damage and additional damage.
