Description

Technical Field

[0001] The utility model relates to a cutting device, in particular to a cutting tool. Background Art

[0002] Cutting tools can be classified into five categories according to the form of the workpiece machining surface: cutting tools for machining various outer surfaces include turning tools, planing tools, milling cutters, external surface broaches, files, etc.; hole machining tools include drills, reamers, boring tools, reamers, internal surface broaches, etc.; thread machining tools include taps, dies, automatic opening and closing thread cutting heads, thread turning tools, thread milling cutters, etc.; gear machining tools include hobs, gear shapers, gear shaving cutters, bevel gear broaches, etc.; cutting-off tools include inserted-tooth circular saw blades, band saws, hacksaws, parting-off turning tools, saw blade mills, etc. In addition, there are also combined tools. According to the cutting motion mode and the corresponding cutting edge shape, cutting tools can be divided into three categories: general-purpose tools such as turning tools, planing tools, milling cutters (excluding formed turning tools, formed planing tools and formed milling cutters), boring tools, drills, reamers, reamers, saws, etc.; formed tools whose cutting edges have the same or nearly the same shape as the cross-section of the workpiece to be machined, such as formed turning tools, formed planing tools, formed milling cutters, broaches, conical reamers and various thread machining tools, etc.; special tools for machining some special workpieces, such as gears, splines, etc. Such as gear shapers, gear shaving cutters, bevel gear planing tools, bevel gear milling cutter heads, etc.

[0003] Cutting tools are tools used for cutting in machining, also known as cutting tools. Most cutting tools are for machine use, but there are also hand-held ones. Among them, cutting tools can be divided into standard blades, beak-shaped blades, round blades, square blades, diamond blades, triangular blades, etc. according to their shapes. And hand-held circular cutting tools are generally used for cutting paper, tape, PVC plates, etc.

[0004] The existing technical solutions have the following defects: when the device is in use, there is a defect of being not easy to prevent slipping. Traditional hand-held circular cutting tools are generally used by directly holding the tool handle by the user. In this way, during the long-term use, the user's hand is prone to sweating, and when the sweaty hand holds the handle, it is easy to slip and drop, which is not conducive to ensuring the stability of taking, thus affecting the cutting accuracy of the device.

[0005] In addition, after the blades of the existing cutting tools are used up, they are exposed outside. If the cutting tool falls, the exposed blades are easy to scratch nearby objects, may also cause damage to the blades themselves, and even may accidentally injure people. During the process of moving the cutting tool, the exposed blades may also scratch the carrier. Summary of the Utility Model

[0006] The main object of the present utility model is to provide a cutting tool, which solves the technical problems that the existing tools are prone to slipping during use, and the blade is directly exposed outside after use, which is likely to cause personal injury and property loss.
