Shearing mechanism of electric scissors

Abstract

The invention relates to a shearing mechanism of electric scissors. The shearing mechanism comprises a fixed block, a shearing shaft arranged on one side of the fixed block and movably connected with the fixed block and a fixed block base plate arranged at an outlet of the fixed block. The fixed block and the fixed block base plate are each provided with a containing groove. The shearing shaft is provided with multiple through holes which communicate with the containing grooves. One end of the shearing shaft is provided with a rotary driving device. One side of the fixed block is provided with a shearing mouth. When the shearing shaft rotates, a scissor mouth is formed by the shearing surface of the fixed block and the edge of the corresponding through hole of the shearing shaft. The through holes in the shearing shaft are located in the circumferential surface of the shearing shaft. The number of the containing grooves in the fixed block and the fixed block base plate corresponds to the number of the through holes in the shearing shaft. The junction of the containing grooves in the fixed block and the fixed block base plate is located at the shearing mouth of the fixed block. When the shearing shaft is rotated, multiple pieces of materials can be sheared. In the shearing process, the cylindrical materials are not likely to roll and are directly cut off by the shearing mouth of the fixed block. The shearing mechanism is simple in structure and high in shearing efficiency.

Description

technical field [0001] The invention relates to a shearing mechanism, in particular to a shearing mechanism of electric scissors. Background technique [0002] Portable electric scissors are mainly used for cutting materials such as thin steel plates, leather, carpets or PVC boards, which can greatly reduce work intensity and improve work efficiency. Common electric scissors are mainly electric scissors with two blades hinged to each other. Most of the existing hinged electric scissors are single-blade shears. Soon, it is inconvenient to replace. Moreover, for some round, thin and hard cylindrical materials, when the hinged electric scissors are cutting, if the shearing force is not large enough or the material to be cut is too hard, the cylindrical material is very easy to get stuck on the cutting edge of the blade. Horizontal sliding will cause great wear and tear on the cutting edge of the blade. If the cutting does not exceed a hundred times, the blade of the articulat...

Common electric scissors are mainly electric scissors with two blades hinged to each other. Most of the existing hinged electric scissors are single-blade shears. Soon, it is inconvenient to replace

Moreover, for some round, thin and hard cylindrical materials, when the hinged electric scissors are cutting, if the shearing force is not large enough or the material to be cut is too hard, the cylindrical material is very easy to get stuck on the cutting edge of the blade. Sliding horizontally will cause a lot of wear on the cutting edge of the blade. If the cutting does not exceed a hundred times, the blade of the articulated electric scissors will basically be scrapped, which brings great losses to the user.
