The present invention relates to a detachable scissors, and more particularly, to a scissors in the form of an intermediate support point each removable component is removable.

Scissors that need to be handled for medical or cooking purposes, especially hygiene, are most suitable for making a pair of scissors components separated from each member rotatably fixed to the support shaft to facilitate cleaning. Or as the industry, such as the development of the food industry has been requested to develop a special kind of scissors.

Under such a request, the applicant is free to open and close the support shaft having a head at one end of a pair of scissors constituent members provided with a blade body in front of the handle body, as described in Japanese Utility Model Publication No. Hei 2-14743. Rotatably fixed, the support shaft is fixed to one member, and the shaft portion of the support shaft has a circular cross section, and the other member has a guide hole having a support through-insertion portion through which the head of the support shaft can be passed at one end. In order to prevent the sliding movement in the guide hole of the support shaft, a detachable scissors was developed to fix the locking member on the head of the support shaft so as to rotate freely.

However, since the detachable scissors are not provided with a stop for preventing the passage of the rotational movement of the locking member at the locking position, the removable shaft passes through the locking position without any restriction even in the locking position where the rotation of the locking member is blocked. The shaft slides along the guide hole. As a result, there was a rattling of the shearing member and the cutting degree was reduced, and there was a dangerous situation that the shearing member was misaligned depending on the location.

In addition, it is important that the user pays great attention to the use, but in this case, the worker cannot concentrate on the cutting side, and the work efficiency is lowered, and there is a problem of accelerating the fatigue of the worker by paying attention. .

The present invention aims to provide inexpensively a detachable scissors that solves this problem.

Detachable scissors according to the present invention is a pair of scissors constituting members (5,6) having the blade body (3,4) is installed in front of the handle body (1,2) the head (7) at one end Open and close freely and rotatably fixed to the support shaft (8) having the support shaft (8) is fixed to one of the scissors constituting member (5) and the shaft portion (9) of the support shaft (8) is formed in a circular cross section On the other end of the scissor member 6 is provided with a guide hole 11 having a support shaft passage inserting portion 10 through which the head 7 of the support shaft 8 can be passed at one end. In addition, the locking members 12 and 21 which can face the head 9 of the support shaft 8 can be freely rotated so as to prevent the sliding movement in the guide hole 11 of the support shaft 8. Scissors that can be detachably fixed so as to be rotatably fixed, and the stopping members 12 and 21 are provided with stop parts 13 and 22 which prevent the passage of rotation of the locking members 12 and 21. It is characterized by being.

Therefore, according to the detachable scissors of the present invention, the support shaft 8, which is the point of rotational movement of the two scissors constituent members 5 and 6, is fixed to one scissors constituent member 5, and the other scissors constituent member (6) is in contact with the shaft portion (9) of the circular cross section of the support shaft (8) inserted through the guide hole (11). In the case of opening / closing operation (cutting operation) of the scissors, the locking members 12 and 21 which are rotatably fixed to one of the scissors constituent members 6 are rotated to shift to the locking position that is the opposite side of the support shaft. When the stops 13 and 22 come to the locking position, the stops 13 and 22 abut against the head portion 7 of the support shaft 8 so that the locking members 12 and 21 pass through the locking positions. The locking members 12 and 21 can be stopped at the locking position automatically and reliably without making it.

In addition, the sliding shaft at the guide hole 11 is prevented by the stop at the locking position of the locking members 12 and 21, in other words, when the scissors are in use, 5, 6) can be prevented in advance.

On the other hand, the separation of each of the scissors constituent members 5, 6 is rotated in the direction of releasing the locking of the locking members 12, 21 (opposite to the rotation to the locking position), and then the support shaft ( 8) slides along the guide hole 11, guides to the support shaft passage insertion part 10 of the support shaft 8, and pulls out the support shaft 8, and is performed.

Other detachable scissors in the present invention have the following effects because they have the above configuration and action. That is, when the scissors are in use, the locking member is reliably stopped at the locking position by the stopper of the locking member, so that the sliding movement along the guide hole of the support shaft is prevented, and rattling occurs in both of the scissors constituent members so that In the work which a user becomes tired and distracted and cut | disconnects, when a user takes care that a fall of the said latching member escapes from a support shaft, etc., such that a fall or the dangerous situation that both scissors structural members shift | deviate during use disappears, and work is carried out. It has an excellent effect so that you can concentrate on safety work without worrying about deterioration.
