Detailed Description

The present invention will be described in further detail with reference to examples, but the embodiments of the present invention are not limited thereto.

Examples

As shown in fig. 1 to 5, a large blade processing tool includes a bottom plate 1, a blade fixing structure disposed on the bottom plate 1, and a blade positioning structure disposed on the bottom plate 1 and engaged with the blade fixing structure.

The blade fixing structure is composed of a block 2 arranged on the bottom plate 1, a V-shaped block 3 arranged on the upper side of the block 2, and a pressing block 4 arranged on the right side of the V-shaped block 3.

Bed hedgehopping piece 2 is hollow cuboid, and V type piece 3 passes through the screw fixation at the last side of bed hedgehopping piece 2, and V type piece 3 stretches out bed hedgehopping piece 2 to the right.

Set up the bed hedgehopping piece into hollow cuboid, can effectual reduction its dead weight, and then reduced the whole weight of frock, also be convenient for simultaneously with bed hedgehopping piece and V type piece reciprocal anchorage.

The right side of the V-shaped block 3 is provided with a V-shaped groove which vertically penetrates through the V-shaped block 3, and an arc-shaped groove matched with the V-shaped groove is formed in the surface, opposite to the V-shaped block 3, of the pressing block 4.
