Abstract

The invention provides a cutting-off knife whose knife blade do not fall of from a sliding device surprisingly at the time of replacement for the knife blade. The cutting-off knife (10) includes: a knife shell (12) extending in front and rear directions, the knife blade (14) contained within the knife shell, the sliding device (15) holding the knife blade (14) to move in the front and rear directions. The sliding device (15) comprises: a sliding device main body (42) which can be located in a hole (14A) of the knife blade (14) and takes a projection 41 as a temporary holding part, and a pressing component (43) which can be joltily connected to the sliding device main body (42); and rear part of the knife blade (14) is clamped between the sliding device main body (42) and the pressing component (43).

Description

technical field [0001] The present invention relates to a cutting blade, and more specifically, relates to a cutting blade having a structure in which the blade does not come off unexpectedly when the blade is replaced. Background technique [0002] A well-known cutting knife is composed of: a substantially C-shaped knife case extending in the front-rear direction; a slider provided to be movable in the front-back direction in the knife case; blade. A locking mechanism is installed between the slider and the blade, by means of the locking mechanism, the blade can protrude from the top of the knife case in stages, and on the other hand, the blade can also be kept in a certain position. [0003] This type of cutting blade is, for example, as described in Patent Document 1, a protrusion is formed on the above-mentioned slider, and a hole is formed in the rear end surface of the blade, and the protrusion is positioned in the hole, by This enables the linkage between the slider...
