Description

Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a length-adjustable blade. Background Art

[0002] Leather is a denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. As a common material, leather is widely used in various industries. During the processing, it is often necessary to use a blade to cut the leather. The existing blade is one-piece. When cutting leather of different thicknesses, blades of different lengths need to be used. However, the existing blade is one-piece. When replacing, the entire blade and the blade holder need to be replaced, which is troublesome. Therefore, a length-adjustable blade is needed to facilitate cutting leather of different thicknesses.

[0033] Embodiment 1: The front blade, the rear blade and the split seat are split, the knife seat is made of low alloy steel, and the rear blade is made of high alloy steel. In the initial state, the clamping block fits the knife seat. When it needs to be used, the connecting rod is pressed, and the connecting rod drives each push rod to slide on the third slide groove. The spring is stretched, and the front blade, the rear blade and the clamping block are inserted along the first slide groove and the second slide groove. The first protrusion and the second protrusion are inserted into the groove. After moving to the appropriate position, the connecting rod is released, and the spring resets and contracts, driving the fourth rack on the clamping block to move downward, and cooperate with the fourth rack on the knife seat, from the upper and lower sides.
