している。 11 is a handle consisting of a side plate 12. The proximal end of the blade 13 is pivotably supported 14 at the front end between the side plates 12. Reference numeral 15 denotes a "shaped stopper having an engagement hole, and is fixed 15f between the side plates 12 at a position close to the base end of the blade 13. Stopper 1
5 is always pressed to the front by a spring 16.
It is also possible to form the stopper 15 with a leaf spring as shown in FIG. 4, and in this case, the stopper 15 itself has a biasing force and extends from the fixed portions 15a to 15e as shown by the imaginary line in FIG. Since it flexes, there is no need for a spring 16 to press the stopper 15 to the front. Reference numeral 15b is an operating portion of the stopper 15 exposed from a through hole formed in the top wall of the handle 11. Reference numeral 17a is a cam projection formed at the base end of the blade, and the upper surface of the tip thereof is curved inward.
The cam projection 17a and the engagement hole 15c are adapted to engage with each other. The tip 13a of the blade 13 is
It is not sharp but rounded and protrudes from the rear end of the handle 11.

係止部材１８との当接により係止される。 Since the present invention is constructed as described above, in order to change the blade 13 from the storage state shown in FIG. 1 to the protruding usage state shown in FIG. A cam protrusion 17a formed at the base end of the blade 13 by rotating the tip 13a of the blade 13 around the shaft 14 by pressing it against a wall, knee 20, etc.
As a result, the stopper 15 is pushed backward against the pressing force of the spring 16, and the cam protrusion 17a is engaged with the engagement hole 15c of the stopper 15. In order for the cam protrusion 17a and the engagement hole 15c to engage with each other by rotation, the engagement hole 15c must be inserted into the cam protrusion 17a inserted into the engagement hole c.
However, in this example, the stopper 1
5 is always pressed toward the front (in the longitudinal direction of the blade length), so the upper wall 15e of the engagement hole 15c of the stopper 15
The blade 13 moves along the curve provided at the tip of the cam projection 17a until the engagement hole upper wall 15e and the upper surface of the cam projection 17a come into contact, so that the blade 13 does not wobble.
Further, the upward rotation is locked by the lower surface of the cam projection 17a coming into contact with the locking member 18.

The upper wall 1 of the engagement hole rotates as shown by the imaginary line in the figure.
A gap is created between the upper surface of the tip of the cam projection 17a and the blade can be rotated, so by pressing the back surface 13b of the blade 13 against a tree branch, knee, etc. and rotating it around the shaft 14. It is stored in the handle 11.

Also, the tip of the blade is rounded rather than sharp, so there is no chance of injury to your fingers when operating it. As in the embodiment, the cam protrusion formed on the proximal end of the blade, whose top surface is curved inward, is engaged with the engagement hole formed on the stopper, which is pressed in the longitudinal direction of the blade length by a spring. If a stopper mechanism is used to stop the blade from the back, there will be no gap between the upper wall of the engagement hole and the upper surface of the cam protrusion, and therefore no rattling will occur during use.
