In the above-mentioned electric scissor blade holder, the arc surface, the first convex arc surface and the second convex arc surface are all arc surfaces, and the radii of the first convex arc surface and the second convex arc surface are equal, And larger than the radius of the arc surface.

In the above-mentioned electric scissor holder, the front side and the back side are both inclined toward the middle from right to left, and the cross-section of the arc surface is a minor arc.

In the above-mentioned electric scissor blade holder, the front side is an outwardly convex arc surface, and the rear side is an outwardly convex arcuate surface.

In the above-mentioned electric scissor holder, the arc surface is a circular arc surface, and the radius is 3mm-5mm.

In the above-mentioned electric scissor blade holder, the first convex arc surface is an arc surface and the radius is 6mm-7mm; the second convex arc surface is an arc surface and the radius is 6mm-7mm.

In the above-mentioned electric scissor blade holder, the upper end of the blade holder body is provided with an upper mounting plate, and the lower end is provided with a lower mounting plate.

The outstanding advantages of this utility model compared with the existing technology are:

The right side of the tool holder body of the utility model is an outwardly convex arc surface, and the right side is connected to the front side of the tool holder body through an outwardly convex arc surface, and the right side is connected to the rear side of the tool holder body. The side surfaces are connected by two convex arc surfaces. The side of the knife holder of the utility model away from the blade is a rounded arc shape. The resistance and friction between it and the cloth are small, making it easy to turn the cloth and make cutting convenient and fast.
