Embodiment 1

[0014] Embodiment 1: On the output shaft of the motor, a reduction transmission mechanism composed of multi-stage reduction gears is connected, and an eccentric wheel 4 is arranged on the gear at the output end, and a connecting rod 3 is arranged outside; on the other side of the connecting rod One end is hinged with the handle end 9 of the movable blade 8; the handle body of the movable blade 8 is substantially perpendicular to the cutting edge, and the hinge shaft 16 of the handle end is in the chute 11, and the chute 11 is arranged on the casing, in the form of Closed groove shape; the hinge shaft 16 is provided with an injection-molded H-shaped handle body 91, and its front end is integrally provided with a locking protrusion 92, which is engaged with the connecting hole on the handle body of the movable blade . The eccentricity of described eccentric wheel 4 and the length of the shank body of movable blade have determined the opening of movable blade and fixed blade cutt...

Embodiment 2

[0017] Embodiment 2: The handle end 9 of the movable blade 8 can also be an integral structure, the fixed hook 19 of the handle body can be punched from the handle body, a spring is fixed on it and the other end is fixed on the knife shaft 10 , and a lock pin 17 is provided at the end of the cutter shaft 10 (see accompanying drawing 3). Other structures are basically the same as in Embodiment 1, and are omitted.

Abstract

The safe electric scissors is for shearing leather and other thick matter. Its transmission mechanism consists of eccentric wheel set on a gear and link rod outside the gear. The link rod has the other end hinged to the handle of the movable blade, the movable blade is hinged to the fixed blade and the feeding port is set outside the opening end on the wrapping casing. The eccentric wheel has small degree of eccentricity and the wrapping casing wraps all the parts except the front edge end. The present invention has simple and compact structure, reasonable configuration and excellent shearing performance.

Description

technical field [0001] The invention relates to an electric scissors, in particular to a safety type electric scissors for cutting thicker and hard sheets such as leather. Background technique [0002] In order to reduce the labor intensity of workers and improve labor productivity and cutting performance, electric scissors have a wider application prospect in industries such as leather and clothing, and some people are also attracted to various improvements. In terms of power, there are two types of power for electric scissors: electric motor or electromagnetic swing. For example, someone has applied for a utility model patent (89219759) called "electric scissors". Its blade is composed of a fixed blade and a movable blade. The power transmission device is a rocking connecting rod. There is a rotating shaft in the middle of the connecting rod, and the movable blade is moved by a pull pin at one end of the connecting rod, so that it moves relative to the fixed blade to form...
