Description of the Invention: [Technical Field] The present invention relates to a screw having a cutting edge, and more particularly to a screw for cutting a chip into a finer one to accelerate the displacement. [Prior Art] In view of the general screw, when locking into the workpiece, it is necessary to apply a large operating torque to lock the use problem. Therefore, there is a kind of screw that can reduce the operating torque. For example, the new patent case of "Fast cut Φ shaving wood screw", Announcement I 2 6 6 0 2 2 "Machine with cutting function" Screw "invention patent case and announcement of the j 3 1 2 8 3 9 "screw" invention patent case. The screws in each of the above cases each have a head, a stem and a tip. A continuous thread is provided on the rod portion, and a cutting edge is provided on the tip portion. The above-mentioned various conventional screws are mainly provided by the setting of the cutting blade on the tip, so that when the drilling or locking is performed on the workpiece, the workpiece can be milled by the cutting blade, and the spiral shape or the linear shape is utilized. The cutting edge discharges the milled scrap material to the rear and discharges it along the screw to the outside, thereby reducing the reaction force of the screw to the workpiece, relatively reducing the torque of the operation, and the workpiece is less prone to cracking. Damage. Although the above-mentioned various conventional screws are provided with a spiral or linear cutter, the effect of the operating torque can be alleviated. However, since the cutting edges on each of the screws are continuous spiral or continuous linear shape, the workpieces milled in the operation are elongated, and the workpiece is first milled down. The material is generally very large, which causes considerable troubles in the subsequent chip removal operation. This is also the main cause of difficulty in chip removal and slow chip removal speed, so it is necessary to find a solution. 201118265 [Summary of the Invention] Therefore, compared with the problem of difficulty in chip removal of the existing screws, the screw of the present invention utilizes the arrangement of the multi-stage blade portion, so that during the operation, the chip material can be cut into a thin section to achieve an accelerated row. The effect of the use of chips. Thus, a screw of the present invention comprises a head and a stem and at least one blade. The rod portion is provided with a continuous tooth portion, the blade portion is disposed on the rod portion, the maximum outer diameter of the blade portion is larger than the maximum outer diameter of the rod portion, and smaller than the maximum outer diameter of the tooth portion, the blade The portion extends along a continuous trajectory, and the blade portion is composed of a plurality of cutting segments. • A screw according to the invention as set forth above, wherein the stem portion of the screw includes the tooth portion and a tip portion, the blade portion being disposed on the tip portion. According to the screw of the present invention described above, the shaft portion of the screw includes the tooth portion and a tip portion provided on either or both of the rod portion and the tip portion. According to the above proposed screw of the present invention, the plurality of cutting segments of the blade portion are continuous serrations. According to the screw proposed by the present invention, the cutting φ section of the blade portion has an irregular or asymmetrical correspondence with the tooth portion. According to the screw of the present invention as set forth above, the execution of the blade portion is in a clockwise circular spiral shape. According to the screw proposed by the present invention, the trajectory of the blade portion is spirally curved in a counterclockwise direction. According to the screw proposed in the above aspect of the invention, the execution of the blade portion is inclined from a right-to-left straight line. According to the screw proposed in the above aspect of the invention, the execution of the blade portion is inclined from a left-to-right straight line. According to the screw proposed by the present invention, the trajectory 201118265 of the blade is linear, and the trajectory is parallel to the shank. According to the screw of the present invention, the screw is further provided with a flattening section which is disposed on the rod portion of the flattening section and is milled compared with the conventional screw. The strip-shaped chip material is disadvantageous for the use of the chip removing; the screw of the present invention cuts the blade into a plurality of cutting segments. When cutting, the cutting piece is cut into the cutting piece by the cutting portion of the blade portion. Smaller, the fine scraps can be quickly discharged from the narrow gap of the screw holes and the screw teeth to accelerate the chip removal. [Embodiment] The screw of the present invention utilizes the arrangement of the multi-stage knife portion, so that in the process of performing drilling or locking into the workpiece, the plurality of blades can cut the chip into a fine I shape and even the workpiece At the first sharp cut, the scrap can also be cut into smaller pieces, thus achieving the effect of accelerating chip removal.

The screws of the embodiments are difficult to use. The spiral and counterclockwise circular screw theory of the present invention is a clockwise arc. The right-to-left line is inclined. It is 11 "line inclined, placed in the central portion 50, the rod portion = straight f-shaped" and the f-blade portion 30 is provided in the drill type implementation = blade: 30 structure, cow In the process of processing, Jiang Mei knows that the whole strip is cut into fine segments, so that the scraps are cut thinner and more sturdy, so the 'fine scraps pass between the narrow screw and the hole of the workpiece. , = faster discharge, and, small shoulder material can greatly reduce the operating torque 'to make it more difficult _ fast. ^I value In the foregoing embodiments, the angle of the screw 100 is clockwise, and the angle of the blade is inclined in a counterclockwise circular shape, clockwise and counterclockwise. The settings are in various arcs and tilt angles, and their functions are the same, and will not be described here. The above is only a plurality of embodiments of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes made by the scope of the invention and the description of the invention.
