Description of the Invention: TECHNICAL FIELD The present invention relates to seismic technology in the field of cutting, and more particularly to a cutting tool having an anti-vibration structure. [Prior Art] During machining, the workpiece causes chattering to the cutting tool, and the sharpness of the cutting is severe. Therefore, a shock absorber (Damper) is installed inside the holder to reduce the chattering of the cutting tool. This method of damping is widely known to the industry, and the related patent documents are numerous, for example: 曰本特开号 2001-96403, 2003-62703, 2003-136301, 2005-177973 唬, or Japanese Patent Publication No. 6-31505, No. 6-31507, or No. 2979823. Among them, the cutting tools described in Cases 301 and 507 both use the inertia of the damper to reduce or eliminate the chatter. However, the 3〇1 patent discloses that the cutting tool is opened from the rear end of the shank. The knives are placed in the shock absorber, and the super-hard core rod is inserted into the remaining hollow portion of the hole. The 507 patent discloses that the center of the shank of the cutting tool forms a deep hole in which a viscous fluid is disposed. balance piece". As disclosed in the 823 patent, the hole of the tool body is inserted into the rod spring, the adhesive elastomer is interposed between the rod spring and the hole, and a cutting head is arranged at the front end of the rod spring, and a friction absorbing material is disposed between the cutting head and the tool body. The vibration energy can be converted into frictional heat, so that the vibration transmitted to the tool body is reduced. The cutting tool of the three patents in the Ting patent case, because the shank has a deep hole, the 201226103 shock absorber is not suitable for the deep hole machining of the small diameter shank, and the boring is not required to perform the hole machining, which increases the processing cost, except for the limit knives. In addition to the straight shank, when the cutting tool is inserted into the hollow portion, the rigidity of the shank is also lowered, and the structure is complicated, which causes problems such as an increase in cost. In addition, the cutting tool disclosed in the 505 patent case uses shock absorbers of different materials in the shank to attenuate the vibration by the contact friction between the shank and the damper. The '703 patent slaughter is in the work 1: the body is loaded with shock absorbing material, absorbs the vibration energy and makes the vibration damper. In addition to the same problems as mentioned above, the shock absorption material of energy absorption needs to be used. High-attenuation clock · copper

Yu Yu's low cost and good chatter suppression effect have become the focus of the 973 patent. This patent discloses a shock-proof cutting tool in which the shank of the cutting tool is provided with a polygonal shape (four), the groove is provided with a shock absorbing member ′ and the groove σ is closed by the cover sheet, so that the damper element is held inside the pocket and cannot be separated. The shape of the damper element may be strip shape, cylindrical shape or empire shape, without connecting the shank, and maintaining a gap between the inner wall of the bag groove, and alternately colliding with the inertia when the vibration is applied The inner wall of the pocket of the position attenuates the chattering of the cutting tool. ^ _ But 疋, the clearance between the damping element and the inner wall of the pocket is too large, and the larger the alternating impact, the less the damping of the cutting tool. If the distance between the damping element and the inner wall is too small, the collision energy is smaller, and the damping effect is naturally not satisfactory. 201226103 In view of this, the inventors thoroughly explored the problems of the prior art. Based on years of experience in research and development and manufacturing of related industries, the inventors actively sought solutions and finally created the new certificate of Taiwan Certificate No. M385422: to improve the problem of customary inventions. And with the excellence of excellence, once again successfully developed a cutting tool with anti-vibration structure. [Summary of the Invention]

The pressing position "can be exposed at the end of the shank base 2 with a pair of locking blades = shank U)' and then combined into a tool 1 〇〇. It is seen that the flow system penetrates the inside of the shank base 20 in the longitudinal direction of the shank to form two open ends. At the open end of the eccentric groove 23, the ball-shaped nozzle 4 〇, after adjusting the orientation of the spray head 40, the lock is locked. The dust bolt 41 located near the open end T of the flow channel 24, the ink nozzle 4 must not leave the flow channel 24, and determine the outflow direction; the other open end of the flow channel 24 is locked into a stop = the plug 4 2 is closed. The through-holes 25 communicate with the outside, and the cutting fluid for the use of the cold portion is rotated into the flow path % via the through-holes 25, and is sprayed toward the blade u through the spherical nozzles 40. : In the shock absorber 50, the flat is made of a screwdriver-like tool: the wide-stand 'inserted into the end of a stud 51 is recessed into an elongated slot 55, and the torque of the accumulated column 51 is guided by the periphery of the column body. Rotating deep man - set in the shank (four) 2G screw groove / 2 = at the same time in the groove π _ - the packing 53 is closed, so that the inside of the screw 2 2 forms a closed space 'guarantee the stud 51 remains in the shank body 20 Do not leave inside. In the third and fourth figures, the density of the stud 51 is greater than that of the tool body. The screw groove 52 is preferably provided so that the two ends of the stud 5 and the bottom surface of the screw groove 52 and the inner surface of the packing member 53 are respectively maintained. - the spacing S, and the top and the valley remain with each other, that is, the screw groove 52 and the threaded portion 54 will have a gap d, the range value is about (4) Κ 5 ugly, some oil or anti-shock oil 60 is injected or smeared in a confined space in which the plugs 53 are sealed by the 201226103 plug. The length of the stud 51 is smaller than that of the screw-like vertical rabbit spear and the ice of the groove 52, and is not locked with each other, and there is a slight gap between the sprayed screw teeth, so that the handle body 2G can be cut. When the operation is continuously vibrating, the chain reaction of the caustic studs 51 causes the teeth of the track segment M to alternately collide with the teeth of the screw groove 52 according to the inertial force W. Thus, the impact portion forms a component force opposite to the direction of the vibration. p, suppress the shank of the shank body 2 〇 even, the kinetic energy of the tool, to achieve the purpose of attenuation or offset of the tremor amplitude, attenuating the shock and the seismic effect. Based on the embodiment derived from the foregoing seismic tool, for example, FIG. 5, the difference is that the stud 71 of the damper 7 is recessed in one of the two end faces by a chamber 76 to accommodate a cylindrical body 77 of a shape conforming. And a closure member 78 is welded to the opening of the chamber 76 to enclose the post 77 in the stud 71 and cannot be disengaged. In this embodiment, the cylinder 77 and the inner wall of the chamber 76 have a tight relationship with the tight fit, and the density is greater than the handle body 2〇 or the stud 71, such as the shank base 20 or the stud 71 material. For iron or ferrous alloys (density approx. 7.87x103 kg/m3), column 77 may be copper or copper-containing alloy (density approximately 8.96x103 kg/m3), lead metal or lead-containing alloy (density approximately 11.34x103 kg/ M3) or a tungsten metal or a tungsten alloy or a tungsten alloy (density of about 19.25x103 kg/m3), such as a large-density metal material or alloy, which is reinforced during the inertial motion of the damper 70 as the shank body 20 vibrates. The threads that the segments 74 and the screw grooves 72 engage with each other alternately impact the force to attenuate the amplitude of the chatter. Next, the closing member 78 welded to the opening of the chamber 76 forms a driving groove 75 on the outer surface of the outer portion 201226103. The groove shape is in the shape of a cross, a cross or other concave shape, and a tool having a matching shape can be inserted to rotate the stud 71 into the knife. The shank body 20 is threaded into the groove 72. Further, the maximum difference between the cutters 1 to 8 and the above embodiment is that the shank 10 is indirectly attached to the shank holder 20 through a holder 8 。. 'The holder 80 is facing away from the side of the holder body 2, and a pair of ridges 8 are formed at an appropriate distance by a plurality of ridges 8
