Disclosure of Invention
The utility model aims to provide a shearing tool which can realize labor-saving shearing, realizes the aim of labor-saving operation and is suitable for shearing materials with certain radian.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a laborsaving mechanism of shearing, is fixed with curved shearing frame on base, the base, and the top of base is fixed with rectangular shape fixed blade, and the upper surface of fixed blade is the recess, and the middle part of shearing frame articulates a square movable blade, and the top and the depression bar of shearing frame are articulated, and the other end of movable blade and the one end of connecting rod are articulated, and the other end and the depression bar of connecting rod are articulated.
The technical scheme of the utility model is further improved as follows: one side of the movable blade is attached to one side of the fixed blade.
The technical scheme of the utility model is further improved as follows: the angle formed between the shearing frame and the base ranges from 45 degrees to 75 degrees.
The technical scheme of the utility model is further improved as follows: and a handle is arranged at one upward end of the pressure lever.
The technical scheme of the utility model is further improved as follows: the shearing frame is hinged with the movable blade and the pressure rod through pin shafts, and two ends of the connecting rod are respectively hinged with the pressure rod and the movable blade through the pin shafts.
The technical scheme of the utility model is further improved as follows: the bottom surface of the movable blade is a flat surface.
The technical scheme of the utility model is further improved as follows: the bottom surface of the movable blade consists of two inclined surfaces, and the two inclined surfaces form an obtuse angle.
Due to the adoption of the technical scheme, the utility model has the following technical effects:
this application laborsaving mechanism of cuting designs two lever structure, and depression bar and connecting rod are one set of lever mechanism promptly, and connecting rod and movable blade form one set of lever structure to realize shearing operation laborsaving purpose.
The upper surface of the fixed blade is the recess, and the aspect is to the shearing of some tubular products and the panel that has the radian, and application scope is wider.
The shearing frame and the base form a certain angle, the shearing frame is arc-shaped, a certain moving range of the movable blade is given, and when an object is sheared in the angle range, the pressing rod is pressed downwards most easily.
The bottom surface of movable blade in this application comprises two inclined planes for the shearing direction is from outside to inside, avoids being shorn the object and outwards removes.
Drawings
FIG. 1 is a schematic view of a labor-saving shearing mechanism of the present invention;
FIG. 2 is a schematic view of another labor-saving shearing mechanism of the present invention;
the cutting device comprises a base 1, a base 2, a cutting frame 3, a fixed blade 4, a movable blade 5, a connecting rod 6, a pressure rod 7 and a handle.
Detailed Description
The technical solution of the present invention will be described in detail with reference to the specific embodiments.
A labor-saving shearing mechanism comprises a base 1 and an arc-shaped shearing frame 2 fixed on the base 1, wherein a strip-shaped fixed blade 3 is fixed above the base 1, the upper surface of the fixed blade 3 is a groove, the middle part of the shearing frame 2 is hinged with a square movable blade 4, and one side of the movable blade 4 is attached to one side of the fixed blade 3; the top end of the shearing frame 2 is hinged with a pressure lever 6, the other end of the movable blade 4 is hinged with one end of a connecting rod 5, and the other end of the connecting rod 5 is hinged with the pressure lever 6. The shearing frame 2 is hinged with the movable blade 4 and the pressure lever 6 through pin shafts, and two ends of the connecting rod 5 are respectively hinged with the pressure lever 6 and the movable blade 4 through pin shafts.
The angle formed between the shearing frame 2 and the base 1 ranges from 45 degrees to 75 degrees. The upward end of the pressure lever 6 is provided with a handle 7.
When the cutting tool is used, the handle 7 is held by hand to open the pressure lever 6, the pressure lever 6 drives the movable blade 4 to open through the connecting rod 5, an object to be cut is placed between the movable blade 4 and the fixed blade 3, and the handle 7 is pressed down forcibly to cut the object.
The shearing frame 2 and the base 1 form a certain angle, the shearing frame 2 is arc-shaped, a certain moving range is provided for the movable blade, and when an object is sheared in the angle range, the pressure rod is pressed downwards most labor-saving.
The upper surface of the fixed blade 3 is designed to be a groove, so that the shearing tool is suitable for shearing materials such as various steel wire meshes, various iron wires and wire rods, and is also suitable for shearing plates and pipes with certain radian.
The lower surface of the movable blade 4 is a blade edge part and can be arranged into a straight plane, as shown in fig. 1; the shearing mechanism can also be composed of two inclined planes, as shown in fig. 2, the two inclined planes form a large obtuse angle, the two inclined planes are one large and one small, the area of the inclined plane close to the hinged position of the movable blade 4 and the shearing frame 2 is small, and the area of the inclined plane close to the hinged position of the movable blade 4 and the connecting rod 5 is far larger than that of the other inclined plane, so that when some round materials are sheared, the shearing direction is from outside to inside, and the problem that the materials are sheared without being placed due to the fact that the shearing force moves outwards is avoided.
