Generally, this type of cutter knife has a groove-shaped blade holder with a lip, in which a blade fixed to a slider is moved forward and backward together with the slider, so that the tip of the blade can come out and go out, and a clip is installed inside the lip of the blade holder. By providing a V-shaped notch row and engaging and disengaging the leaf spring built into the slider, the blade can be moved to both the protruding and retracting positions, regardless of the shortening of the overall length of the blade due to the renewal of the cutting edge of the blade, which is often done by breaking off the blade. It can be clicked arbitrarily.

In general, release of the blade position holding constraint by a click stop is not only possible by operating a slide, but also undesirably in heavy processing where a large cutting reaction force is applied to the blade with a protruding tip, such as cutting plywood. This can occur relatively easily, so it is necessary to perform a click-stop lock.

(Means for Solving the Problems) This invention is based on a blade holder which has a groove shape with a lip and is provided with a row of V-shaped notches for click-stopping on one side of the inner edge of the lip. A click-stop slide cutter knife that combines a slider that can move forward and backward with a blade locked at its tip along the groove under the engagement and disengagement of a leaf spring with respect to a row of shaped cuts, and a sliding knob for operating the blade. A row of U-shaped notches for locking is provided on the other side of the inner edge of the lip of the holder, corresponding to a row of V-shaped notches, while a row of U-shaped notches is selected for the slider by lateral movement in a direction that intersects with the advance/retreat direction. a latch for engagement and a spring for biasing the latch in the engagement direction;
The latch is pulled back through the flexible rod against the spring in the direction of its unlocking by means of a downwardly pointing pin which engages an eye ring formed at the end of the flexible rod. This is an auto-locking slide cutter knife with a click stopper provided with a protrusion on the lower surface of the sliding knob.

(Operation) When the sliding knob 3 is moved forward as shown by the arrow α in FIG. 2a, the downward protrusion 3b moves as shown in FIG. 3b, causing the flexible rod 8a to bend ( (solid line in the figure), the spring receiver 8 resists the spring 7.
The latch 6 that is fitted with this moves in the direction of the arrow β, and the tip 6a of the latch 6 is pulled out from the notch (upper imaginary line in Fig. 3a) of the U-shaped notch row 2b, and the lock is released. Since the sliding knob 3 comes into contact with the stopper 4g of the slider 4, the slider 4 is moved forward along with it, and as a result, the tip of the blade engaged at 4a also protrudes. When the forward operating force applied to the sliding knob 3 is loosened at any position where the tip of the blade protrudes, the partial protrusion of the window hole 4e of the leaf spring 5 and the recess (third (lower imaginary line in Figure a) is selectively engaged, and at that position the lateral groove 4
The restoring force of the spring 7 in i causes the latch 6 to protrude into the recess of the U-shaped notch row 2b, and a selective locking occurs automatically. This operation is almost the same when the sliding knob 3 is moved backward.

(Effect of the invention) By simply moving the sliding knob back and forth, the slider and therefore the blade are first unlocked each time, and then the slider moves back and forth in a follow-up manner, so that the blade tip can be protruded or retracted with appropriate clicks. A positive relocking of the slider and thus of the blade is automatically achieved when the sliding knob is freed in this extended or retracted position, and thus during the cutting operation with the blade, no force is applied to the blade. A reliable locking that prevents the blade from undesirably retracting due to reaction forces or resistance is achieved with a simple construction.
