Labor-saving bolt clipper

Abstract

The invention relates to the technical field of manual tools, in particular to a labor-saving bolt clipper. A labor-saving bolt clipper comprises a first tool bit, a second tool bit, a first handle, a second handle and a pressing plate, the first tool bit, the second tool bit, the first handle and the second handle are all rotationally arranged on the pressing plate, the first tool bit is connected with the first handle in a meshed mode, and the second tool bit is connected with the second handle in a meshed mode. When a bar is sheared, force is applied to the tail ends of the first handle and the second handle respectively, the first handle and the second handle rotate around the bolts at the upper ends respectively, the cylindrical gear at the upper end of the first handle drives the cylindrical gear at the lower end of the first tool bit to rotate, and the cylindrical gear at the upper end of the second handle drives the cylindrical gear at the lower end of the second tool bit to rotate; and the included angle between the two tool bits is gradually reduced until the bar material is cut off. An original bolt connection mode is replaced with a gear meshing connection mode, when the opening angles of the cutting edges are the same, the opening angle of the handle is increased, the stroke is increased by doing the same work, and the labor-saving purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of hand tools, in particular to a labor-saving bolt cutter. Background technique [0002] The bolt cutter is mainly composed of a cutter head, connecting arm, handle, etc. The ordinary bolt cutter head and connecting arm are connected by bolts, and the two connecting arms are also connected by bolts. When cutting objects, by opening the handle , the cutter head is also opened, put the object on the cutting edge, and then merge the handle, the cutter head is also closed to realize the cutting function. Although the above structure uses the principle of leverage to achieve the purpose of labor saving, but when cutting For objects with a harder or larger diameter, the required force will increase, and long hours of work will increase the labor intensity of the operator. This defect exists in traditional bolt cutters. Contents of the invention [0003] The purpose of the present invention is to solve the prob...

[0002] The bolt cutter is mainly composed of a cutter head, connecting arm, handle, etc. The ordinary bolt cutter head and connecting arm are connected by bolts, and the two connecting arms are also connected by bolts. When cutting objects, by opening the handle , the cutter head is also opened, put the object on the cutting edge, and then merge the handle, the cutter head is also closed to realize the cutting function. Although the above structure uses the principle of leverage to achieve the purpose of labor saving, but when cutting For harder or larger-diameter objects, the force required will increase, and long-time work increases the labor intensity of the operator. This defect exists in traditional bolt cutters.
