However, as shown in the fifth and sixth figures of the case, it is implied in Fig. 1 and into the second figure. There are various drawbacks in the attacking of the workpiece. On the same semi-circular surface, when the scraping of the workpiece is only accumulated in the concave of the semi-SJ arc surface of the screw shank, and the other semi-circular surface of the screw shank is not provided with a groove, it is difficult to Attacking the workpiece scraps, resulting in poor distribution of the scraps, resulting in screw stability is not ideal. The lock of the needle is sweet! ^The plurality of grooves on the needle bar of the screw of the case have a circular degree of separation, and the diameter of the circle is gradually reduced from the middle to the both ends, and the formation of the plurality of grooves The shank makes the core lines parallel. Therefore, when the screw is used to strike the workpiece, the M288909 * the linear arrangement of the ridges on the circumference of the plurality of grooves will form a full contact with the workpiece, resulting in a large resistance of the ridges during the attack. If the nail rod is difficult to be cut once, it is easier to be wound on the rim of the nail rod, which affects the screw attack speed of the screw, and it is difficult to quickly lock the missing workpiece. 3. The line of the plurality of concave ridges on the shank of the screw will form a full contact phenomenon with the tapping workpiece at the same time, resulting in a large frictional resistance in the smashing of the spurs, which consumes the locking force. The screw is locked and tapped into the workpiece, which is troublesome and inconvenient to operate. • 4. When the screw is locked to the workpiece, the locking force is used, so that when the workpiece is locked, the excessive locking force is applied, which causes the tooth pattern of the screw to be damaged, and the screw is more fragile on the locking workpiece. (2) Application No. 9021 7526 "Fracture-Resistant Screws" - The case has a chip-discharging guide groove on the body of the screw rod, whereby the chip-discharging guide channel discharges the material of the workpiece Chip residue. According to the screw insertion condition diagram shown in the fourth and the figure of the case, the following drawbacks are generated on the workpiece: • 1. The direction in which the chip guide groove is formed on the body of the screw rod It is parallel with the center line of the rod body. When the screw taps the workpiece, the linear arrangement of the tooth line around the circumference of the chip guide groove forms a full contact phenomenon with the workpiece, which causes a large frictional resistance when the tooth pattern is tapped. , reduce the speed of attacking the workpiece. 2. Because the chip guide groove on the body of the screw rod is used to attack the workpiece, it is necessary to rotate the screw with a larger force, so that the tapped end of the threaded hole of the workpiece is easy to produce during the tapping process. The I seam, in addition to the structural strength of the guard, also reduces the locking effect between the screw and the workpiece. 3. Because the chip guide groove on the body of the screw rod is used to push out the workpiece 5 and M288909, the chip generated when cutting the workpiece _ ^ ^ $ is due to the rough or blockage of the car, and cannot be smoothly launched. As a result, the frictional resistance of the knife is increased, and the speed of the screw is further delayed, and the effect of rapidly tapping the threaded hole cannot be achieved. 4. According to the third point mentioned in the previous section, due to the increase of the strength of the friction, the force exerted by the force exceeds the tooth pattern of the screw and can be withstand the target of the 曰7 target, which is prone to breakage of the tooth pattern, causing time in vain.

When the self-tapping screw 10 is used to tap a threaded hole on a workpiece made of wood, plastic or the like, the user can clamp the end of the hand or the power tool such as a screwdriver to the rotating portion of the screw head u. (), using the aforementioned tool to rotate the self-tapping screw 1〇, and the screw 13 is used to cut the workpiece, forcing the workpiece to be tapped out of the threaded hole to smoothly complete the tapping of the threaded hole and screwing the self-tapping screw 10 The main purpose. Moreover, the self-tapping screw 10 of the present invention generates the chips generated when the threaded hole of the workpiece is tapped; the first row angle i 2 i 7 M288909 which is connected by the thread 13 and the surface of the rod body 1 2, The chip evacuation angle 122 accelerates the push stack and cannot push the row backwards smoothly. It has been caused by the coarser material or the blockage (4) pushing (4) out of it, resulting in an increase in frictional resistance. The first chip discharge arranged by the self-tapping screw 1 〇椁# corner 121 and the first _ chip is suspected. When the tapping screw and the screw 13 on the rod body 12 are matched, the process of the threaded hole of the thread I can be The effective speed of the Tong Tong #乂❺^ leaf pushes the speed, to the male politician to reduce the self-tapping screws 1 〇 8 flat m & and the heart is abusive resistance, therefore, 7 users can use the self-tapping snail (2) Also twist the wire 1 快速 and quickly tap the threaded hole.

The dragon makes the self-tapping screw, please refer to Fig. 5, which is another implementation of the self-tapping screw of the present invention. The 亥 view 5 Hai self-tapping screw 30 includes a screw head 31, which is disposed under the screw head 31.曰 4 曰 touch. ^ ° , dry 32 , and a screw ring 33 on the rod body 32 and other members, characterized in that the corresponding position of the tip end 32 尾 of the rod body 32 is provided with a first chip edge angle 321 (such as 帛 7 The figure is shown, and is adjacent to the first chip-discharge angle 321 of the rod 32 and is a different opposite bank position, respectively provided with a second chip discharge angle 322 (as shown in Fig. 6). Referring to FIG. 5, the upper end of the tapping angle 321 of the tapping screw 30 is set to the inclined side 3210. Further, as shown in Figs. 6 and 7, the first chipping angle 321 and the second chip discharging angle 322 of the self-tapping screw 3 are set to a cross shape. Referring to FIG. 8 again, this embodiment is substantially identical to the embodiment of FIG. 5. The only difference between the embodiment and the first row of the shank 321a of the rod 32a is adjacent to the M288909* and is a different position. a second chip evacuation angle 322a (shown in Figures 9 and 10), the first chip removal angle 3 on the rod body 32a of the self-tapping screw, the second chip discharge angle 322a, and the rod body coffee The threading of the screw can greatly increase the pushing speed of the chip during the process of tapping the threaded hole, so as to effectively reduce the frictional resistance when the self-tapping screw is rotated, so that the user can use the self-tapping screw and quickly Tap the threaded hole. ▲ It can be seen from the above description that the self-tapping screws 10 and 30 can greatly increase the pushing speed of the scraps, effectively reducing the frictional P force that is applied when tapping the threaded holes, and quickly and labor-savingly complete the tapping of the threaded holes.
