Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention mainly relates to medical treatment,
The present invention relates to an improvement of disassembled scissors which can disassemble and clean scissor components in the fields of hairdressing, gardening, cooking, etc., and always ensure clean and hygienic use.

[0002]

2. Description of the Related Art A conventional scissor-type scissors of this type includes a pair of scissors elements having a connecting portion between a blade portion and an operating handle portion, the connecting portion being an opening and closing center. The longitudinal axis of the rectangular head intersects the direction of the blade at an obtuse angle with the opening / closing axis element that cuts off both sides of the circular head of diameter and forms the latching jaw as a rectangular head of approximately axial diameter width in the axial direction. As the non-rotation that allows the axial movement against the bias of the spring while allowing the shaft part and the rectangular head to protrude from the sliding contact surface with the other scissor element, it is attached. On the other hand, a notch is formed in the receiving seat portion to which the rectangular head is fitted and supported, and a jaw is formed through the notch. After passing the rectangular head through the notch, one of the scissor elements is rotated to open and close the opening / closing shaft element. 2. Description of the Related Art A structure in which a locking jaw and a receiving seat are engaged with each other is known.

When the direction of the rectangular head of the opening / closing shaft element protruding from one scissor element coincides with the direction of the notch in the receiving seat of the other scissor element, the pair of scissor elements opens and closes. Since the shaft elements can be separated in the axial direction, clean and sanitary use can always be ensured by the cleaning means.

[0004]

However, in a configuration in which a pair of scissor elements are separated in the axial direction of an opening / closing shaft element that is perpendicular to the opening / closing surface of the scissors, separation at a predetermined angle is simple. The pair of scissors elements may be inadvertently separated from each other and fall down due to excessive opening during use or carelessness at the time of separating work, causing the scissors or the function added thereto to be lost at an early stage.
Not only is the risk to the human body, especially the feet, extremely high,
There are many drawbacks, such as frequent damage to equipment, floors, etc. due to falling collisions and stabs.

[0005] The above drawbacks can be solved by providing a lock mechanism or a stopper mechanism and a release mechanism by manual operation in order to ensure safety, but the product cost is increased due to an increase in the number of components. Rise and the handling operation becomes complicated and cumbersome.Since the simple configuration that does not increase the number of parts prevents inadvertent dropping and secures safety and convenience of handling operation, It is an object of the present invention to provide inexpensive disassembled scissors that can be used cleanly and hygienically, which is an essential need.

[0006]

(4) is provided with a notched shaft hole (5) cut off so as to be detached in the blade edge or dorsal edge direction of the blade part (1), and on both sides of the bowl-shaped notch shaft hole (5). A blade part at the edge in the cutting direction to allow rotation along the spherical surface at a predetermined opening angle
(1) A notch (6) for detachment with a width is formed, and the connecting portion (3) between the first scissor element (A) and the second scissor element (B) has a notch shaft hole (5). A bowl-shaped recess is fitted as a spherical seat (7), and an opening / closing shaft element (4) having a head (10) in contact with the spherical seat (7) is fitted with a notched shaft hole (5) and a shaft hole. (8), and the first scissor element (A is connected to the second scissor element (B) by fastening means having a spring biasing means in the direction of bringing the second scissor element (B) into close contact with each other. A) against second scissors element
With (B) opened at a predetermined angle, force is applied in the direction along the spherical surface so as to remove the notch shaft hole (5) of the second scissor element (B) from the shaft of the opening / closing shaft element (4). And the presence of the notch (6) for releasing the blade portion (1) width allows the second scissor element (B) to rotate with respect to the first scissor element (A).
The second scissor element (B) can be rotated and separated from (A) to prevent inadvertent dropping, thereby ensuring safety and convenience of handling operation.

Therefore, as compared with the conventional product, it can be manufactured easily without particularly increasing the number of parts and without complicated processing means and assembling means. , And can be provided at a manufacturing cost that is almost the same as the conventional one at a high quality / cost ratio.
