択的に位置する。 Next, a slide member 44 selectively rotates the lever member 34 between the locked position and the unlocked position.
I will explain about it. The slide member 44 has a semi-circular engagement protrusion 47 protruding from the center of both sides of the inner surface of a thin plate-like base 45, and an operating protrusion 46 on the outer surface.
is installed protrudingly. And this slide member 44
The base portion 45 is slidably brought into contact with the lower surface of the storage portion 5, the engaging protrusion 47 is engaged with the guide groove 40 of the lever member 34, and the operating protrusion 46 is slightly retracted from the guide groove 29. It is arranged so as to protrude above the section 5. Therefore, by operating the slide member 44 by a small stroke, the lever member 34 is actuated as will be described in detail later, and can be selectively moved between the locked position of FIG. 9 and the unlocked position of FIG. 10. Located in

図参照）。 The engagement protrusion 47 is connected to the lever member 34.
When it reaches the right side of the rotation axis 35, the lever member 34
As described above, is formed in an inverted C shape and has a valley surface 34a, and is supported with the valley surface 34a on the upper side, so that the distance between the side plate 2 and the lever member 34 on the right side of the rotation shaft 35 is Since it is gradually becoming shorter, the slide member 44 rotates the lever member 34 in the clockwise direction in FIG. 10. When the engaging protrusion 47 engages with the engaging recess 41, the locking part 39 comes into contact with the inner surface of the side plate 2 and holds the lever member 34 in the locked position shown in FIG. At this time, the locking portion 37 of the lever member 34 is engaged with the engagement groove 24 to lock the jaw portion 7 of the cutter (9th
(see figure).

また逆に、スライド部材４４を第９図左方向へ

いう優れた効果を奏する。Effects of the device As detailed above, this device can securely hold the blade part of the cutlery in the sheath, and also has the advantage that all the components are stored in the storage section and the operating protrusion is slightly outside the storage section. Since the lock only protrudes from the top, the lock will not be released due to unexpected external force applied when carrying, etc., and the lock can be easily locked and released by operating the operating protrusion with only a slight stroke. It will be done. Moreover, unlike the conventional case, there is no need to provide a locking recess in the handle of the cutlery, so dirt does not adhere to it, and there are excellent effects in that there are no hygiene problems.
