Abstract
The utility model discloses a hole shearing device. The device comprises two shearing arms (1). Handles (6) are provided on one side of the two shearing arms (1). The other side passes through a rotation shaft (2) with an intersection, and bent into the shape of flat plate after forming of the rotation connection. A hole shearing cutter I (4) and a hole shearing cutter II (3) are respectively connected to the inner surface on the other side of the two shearing arms (1), wherein the hole shearing cutter I (4) and the hole shearing cutter II (3) are disposed opposite to each other. The utility model can not only improve working efficiency, but also ensure yield of the products, and improve quality of products.
Description
Technical field
The utility model relates to a kind of blooper.
Background technology
The general employing drawn a circle earlier on product when some industrial products need carry out the drilling operation at present, subtract according to drawn circle then and cut, this method is complex procedures not only, thereby causes inefficiency, and the weak effect of in the process of shearing, shearing, be easy to cut substandard products.
Summary of the invention
The invention provides a kind of blooper, it not only can be increased work efficiency, and can guarantee the yield rate of product, improves the quality of products.
The utility model has adopted following technical scheme: a kind of blooper, it comprises that two cut arm, two sides of cutting arm are handle, the opposite side intersection is bent into tabular after being rotationally connected by rotating shaft formation, be connected with respectively at two inner surfaces of cutting the arm opposite side and cut hole cutting knife I and cut hole cutting knife II, cut hole cutting knife I and cut hole cutting knife II and be oppositely arranged.
Describedly cut hole cutting knife I and cut hole cutting knife II and cut the inner surface of arm opposite side for fixedlying connected with two respectively.Cutting hole cutting knife I and cutting hole cutting knife II is dismountable flexible connection with two inner surfaces of cutting the arm opposite side respectively.The described hole cutting knife I that cuts is the inner column structure that is provided with through hole with cutting hole cutting knife II, the aperture of wherein cutting hole cutting knife I is greater than the aperture of cutting hole cutting knife II, cut hole cutting knife II and be set to blade with the opposite face of cutting hole cutting knife I, the blade of cutting hole cutting knife II is provided with the triangle blade of protrusion, and the blade of cutting hole cutting knife I is set to the plane blade.The described hole cutting knife I that cuts is the inner cylindrical structure that is provided with through hole with cutting hole cutting knife II.The termination of described handle is provided with handle.
The utlity model has following beneficial effect: the arm of cutting of the present utility model is provided with two and cuts the hole cutting knife, one cuts the aperture of the aperture of hole cutting knife greater than another cutting knife, hold like this and cut arm and make two to cut the hole cutting knife and can realize cutting hole operation after involutory, not only simple in structure, easy and simple to handle, improve the operating efficiency of cutting the hole, and the hole shape standard that cuts, improved the yield rate of product.The blade of cutting the hole cutting knife that aperture of the present utility model is little is provided with the triangle blade of protrusion, and the blade of cutting the hole cutting knife that the aperture is big is set to the plane blade, can be convenient to the hole is sheared fully when cutting the hole like this.Of the present utility model two cut hole cutting knife and two cut the surface of arm opposite side both can be for having fixedlyed connected.Also can be dismountable flexible connection, like this can be according to the demand that satisfies the different users, fixedly connectedly can be used to shear hard material, dismountable flexible connection can be so that change cutting knife.
