Technical Field

[0001] The utility model relates to the technical field of shear edge testing, in particular to a shear edge testing machine. Background Art

[0002] After assembly, all scissors, especially garden shears used for gardening, undergo manual inspection to determine if their sharpness meets factory specifications. However, the current method of inspecting the cutting edge of garden shears relies on manual testing, which is both inefficient and labor-intensive. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a circular shears blade edge testing machine to improve detection efficiency and reduce workers' labor intensity.

[0005] frame;

[0006] A fixing mechanism is mounted on the frame. The fixing mechanism consists of a lower fixing assembly and an upper fixing assembly, each used to fix the two handles of the scissors. The upper fixing assembly includes a movable bracket, an upper locking block mounted on the movable bracket, and a first cylinder. One end of the movable bracket is connected to the output end of the first cylinder. The first cylinder drives the upper locking block away from or close to the lower fixing assembly to realize the opening and closing of the scissors.

[0007] The material loading mechanism is installed on the frame. The material loading mechanism includes a material placing assembly and a material pushing assembly arranged on the material placing assembly. The material placing assembly is used to place the material to be tested, and the material pushing assembly is used to move the material to be tested into the shearing range of the scissors to be tested.
