Therefore, the screw will damage the wiring on the circuit board during the tightening process. If the damage is serious, the circuit board may not work. 〇 [Summary of the Invention] [0003] In view of the above, it is necessary to provide a screw that can prevent the wiring of the board from being broken during the tightening process. [0004] - a screw 'includes - a nut and a threaded rod connected to the nut, the threaded rod is close to the convex portion of the position - the card HJ member, the securing member is fixed against the wearer, and the prevention A sanding pad is in contact with the production portion of the nut, the wear pad being made of a flexible material having elasticity. 0005[0005] Compared with the prior art, the screw of the present invention protrudes from the threaded rod near the nut, and a P-square honing (6) made of a flexible material is clamped on the fastener. It is very convenient and practical to prevent damage to the circuit board wiring during the tightening process. [Embodiment] [0006] Please refer to FIGS. 1 to 3 'The preferred embodiment of the screw 100 of the present invention includes a nut 10, a fastener 20, and Threaded rod 3〇 and a wear pad 4〇. Among them, J wear-resistant 塾 40 is made of flexible material with elasticity, such as plastic (pc) 099126705 or nylon (Nyl〇n). The material of the other parts except the wear-resistant 塾40 is deleted. Page 3 of 10 099204684,0 201207256 It is made of metal, such as steel or iron. [0010] [0010] [0010] [0010] [0010] The nut 1D is formed by a - cylindrical body 12 and a second cylindrical body 14, the top of the first cylindrical body 12 is provided with a cross recess 16 (also The second cylinder 14 is disposed at the bottom of the first cylinder 12, and the diameter of the second cylinder 14 is smaller than the diameter of the first cylinder 12. In other embodiments, the nut 1〇 may also be only a cylinder, and the body may be designed as needed. The threaded rod 3 is disposed below the second cylindrical body 14 . The fastener 20 protrudes from the threaded rod 3 且 and is adjacent to the second cylinder 14 . The fastener 20 is also cylindrical and has a diameter smaller than the first portion. The diameter of the second column 14 is wide, and a groove is formed between the fastener 2 and the second cylinder 14. The wear pad 40 is a ring and the inner wall thereof 42. Opening a slot 44, the outer diameter of the wear pad 40 is the same as the diameter of the second cylinder 14. The inner diameter of the wear pad 40 is the same as the diameter of the groove 5〇. The diameter of the portion of the groove 44 of the pad 40 is the same as the diameter of the card. The thickness between the slot 44 of the wear pad 40 and the top or bottom of the anti-i pad 40 is the same as the width of the groove 50. Please refer to FIG. 3 again. When assembling, the wear pad 4 can be directly stuck on the fastener 20 due to the elasticity of the wear pad 4, and the wear pad 40 and the second cylinder 14 are seen after the card is attached. It resembles an integral cylinder, and the wear pad is very firmly stuck to the fastener 20. In the application, since the wear pad 4〇 made of a flexible material is installed on the bottom of the nut 1〇, it is very convenient and practical to prevent the circuit board wiring from being damaged during the tightening process. Actual 099126705 Form No. Α0ΗΗ Page 4 of 10 0992046849-0 201207256 This screw 100 can be used in any occasion where a gasket is required. It is also convenient to replace the wear pad 40. [0011] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
