The connecting wall 11 32 has a substantially semi-arc shape, and its two ends are respectively connected to the arc of one of the two side walls 11 31 facing the central axis direction of the head portion 11. The bottom wall 1133 and the two side walls 11 31 and the connecting wall 1132 are rounded and smoothly connected. The threaded portion 13 has a rod-like structure with a thread 131 formed thereon. In the present embodiment, the curved end surface 111 is convex toward the direction away from the thread portion 13. Referring to Figures 1 and 3, the driver 200 for use with the fastener 100 includes a stem portion 21 and a drive portion 23 provided at the end of the stem portion 21. The rod portion 21 has a substantially stepped shaft shape and includes a main body 211 and a grip portion 213 connected to the end of the main body 211. The driving portion 23 has a substantially cylindrical shape, and is axially protruded from the other end of the main body 211 with respect to the grip portion 213. The shaft diameter of the driving portion 23 is larger than the shaft diameter of the main body 211. A plurality of driving teeth 231 are protruded in the radial direction from the plurality of detaching grooves 113 on the end surface of the driving portion 23 corresponding to the head portion 11. In the present embodiment, the driving portion 23 includes four driving teeth 231 which are evenly disposed on the end surface of the driving portion 23 and adjacent to the peripheral position, opposite to each other. Each of the driving teeth 231 has a strip shape and the structure matches the dismounting groove 113 on the head portion 11. Each of the driving teeth 231 corresponding to the connecting wall 1132 of the one of the fastening grooves 100, the two side walls 11 31 and the bottom wall 1133 are respectively provided with a substantially semi-circular arc-shaped mating surface 2311 and two ends of the mating surface 2311. The second surface 2313 and the top surface 2315 are abutted, the mating surface 2311 and the two abutting side surfaces 2313 are rounded, and the top surface 2315 and the mating surface 2311 and the second abutting side surface 2313 are rounded. Referring to FIG. 4, the punch 300 for forming the fastener 100 includes a body 31 and a punch 33 formed by recessing the end of the body 31. The body 31 is a cylindrical knot. 099146799 Form No. 1010101 Page 5 of 15 0992080395-0 [0015] 201226725 The structure may also be a rod-like structure having a rectangular or other shape in cross section. The specific structure of the Chongshu 3 3 corresponds to the structure of the dismounting groove 11 3 of the head 11 of the fastener 10, which is included in the groove 331 and the punching edge 332 of the plurality of tooth structures provided on the peripheral wall of the groove 331. . The punching edges 332 are uniformly distributed in the circumferential direction. The two sides of the punching edge 332 are smoothly connected to the peripheral wall and the bottom wall of the recess 331. In the present embodiment, the number of the punching knives 332 is four, which are evenly distributed on the peripheral wall of the groove 331 and are opposite to each other. 1 to 4, when the driving member 200 is used to drive the fastener 1〇〇, the driving portion 23 of the driving member 200 is inserted into the dismounting groove 113 of the head 11 of the fastener 100, wherein the driving portion 23 The mating surface 2311 mates with the connecting wall 1132 of the fastener 100. The abutting side surface 2313 and the side wall 1131 are fitted to each other and a circumferential direction thrust is applied to the side wall 1131 by the driving teeth 231, so that the fastener 1 is rotated in synchronization with the driving member 2''. [0017] When the fastener 300 is used to form the fastener 1', the head 11 is punched by the punch 33, thereby forming the removal groove 113 of the head. [0018] It can be understood that the number of the dismounting slots 113 of the fastener 1 is not limited to four in the embodiment, and may also be three, five or six, etc., and the specific number of the disassembling slots 113 may be according to the actual design. Depending on the needs. [0019] Correspondingly, the specific number of the driving teeth 231 of the driving member 200 is not limited to the fourth in the embodiment. It may also be three, five or six, and the specific number and structure of the driving teeth 231 are used together. The number and structure of the disassembly slots 113 of the fasteners 1 are corresponding. [0020] Similarly, the number of punching edges 332 of the punch 300 is not limited to four in the embodiment, and may be three, five or six, etc., the specific stamping knife 332 099146799 Form No. A0101 Page 6 / A total of 15 pages 0992080395-0 201226725 [0021] 002 ❹ [0022] [0023] 099146799 ~ and 1 port structure corresponding to the number and structure of the removal slot 113 of the fastener 1 to be emptied. Since the disassembly groove 113 on the fastener 不 does not intersect the central axis of the head - a disassembly tool such as a plum blossom screwdriver, a screwdriver, a screw, a file, etc., is used to remove the structure to meet the structural speciality. Or assemble the anti-disassembly requirements of the temple. In addition, since the drive _31 of the driving member 200 cooperates with the detaching groove ι 3 of the fastener (10), and the detaching groove ΐ3 仏 is oriented in the direction of the circumference of the head, the arm is long when disassembled, and the force can be generated by using The big torque makes it effortless. When the abutting side surface 2313 of the driving tooth 231 of the driving member 2GG abuts against the side wall 1131 of the dismounting groove 113 to drive the fastener (10) to rotate, the side surface such as the side wall 1131 is in surface contact and the driving angle is twisted. Passing the maximum torque, with the same driving efficiency. The bottom wall ιι 33 of the detaching groove 113 is smoothly connected with the side wall 1131 and the connecting wall 1132, so that the *matching detaching tool slides out of the detaching groove 113 to have a tamper-proof function, which can also prevent stress concentration. Reduce wear and rubbing when the drive member 2〇〇g is combined. In addition, by providing a plurality of disassembly grooves 113, the force per per-removal groove 113 can be reduced, thereby reducing wear during disassembly and prolonging the service life. It will be understood that the stem portion 21 of the driving member 2QG may also be curved, and the grip portion 213 thereon is coaxially connected to the main body 211.
