Abstract
The invention discloses a cutting tool. The cutting tool comprises a tool bit and a tool handle, wherein the tool bit is cylindrical, one end of the tool bit is open, the other end of the tool bit is closed, the tool handle is connected with the tool bit and is fixedly arranged at the closed end of the tool bit, a circle of cutting edges are arranged on the end face of the open end of the tool bit, the cutting edges are perpendicular to the end face of the open end of the tool bit, a spring is arranged in a cylinder of the tool bit, and one end of the spring is fixedly arranged on the inner end face of the closed end of the tool bit. The cutting tool is simple in structure and convenient to use, and portions which are cut off can be taken out conveniently.
Description
Technical field
The present invention relates to a kind of cutting tool.
Background technology
In prior art, there is a class cutting tool to be mainly used in offering the circular hole that door lock is installed on door, operation principle is to utilize a columnar cutter head, the round mouth of cutter head is provided with a circle cutting edge, utilize cutting edge to cut on door-plate, on door-plate, cut a circular hole, the part being cut can be stayed in columnar cutter head, after having cut like this, the part that is cut of staying in cylinder is difficult for taking out, and uses very inconvenient.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of simple in structure, be cut part and be convenient to take out, cutting tool easy to use.
The technical solution used in the present invention is such: a kind of cutting tool, comprise cutter head and handle of a knife, described cutter head is cylindrical shape, an end opening, one end sealing, handle of a knife is connected with cutter head, the one end that is fixedly installed on cutter head sealing, the end face of one end of cutter head opening is provided with a circle cutting edge, and cutting edge is vertical with the end face of cutter head opening one end, in the cylinder of described cutter head, be provided with a spring, one end of spring is fixedly installed on the inner side end of cutter head sealing one end.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, simple in structure, be cut part and be convenient to take out, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Mark in figure: 1 is cutter head, 2, handle of a knife, 3, cutting edge, 4, spring.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 1, a cutting tool, comprises cutter head 1 and handle of a knife 2, and described cutter head 1 is cylindrical shape, one end opening, one end sealing, handle of a knife 2 is connected with cutter head 1, is fixedly installed on one end of cutter head 1 sealing, the end face of one end of cutter head 1 opening is provided with a circle cutting edge 3, cutting edge 3 is vertical with the end face of cutter head 1 opening one end, is provided with a spring 4 in the cylinder of described cutter head 1, and one end of spring 4 is fixedly installed on the inner side end of cutter head 1 sealing one end.Using cutting tool to cut after door-plate perforate, the part being cut in the cylinder of staying cutter head is subject to the elastic force of spring and deviates from cylinder, uses very convenient
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
