Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a screw, and more particularly to a combination screw. [Prior Art] [0002] One of the most basic components of a screw-type mechanism device. When assembling components, the mechanism equipment requires at least two special types of screws to fix the separated parts together. For example, in the case of a computer and a server, there are usually a plurality of screws of different sizes to fix different components such as a heat sink, a motherboard, a hard disk, an optical disk drive, and an expansion card. However, the screw of the specification is small. Small size and other reasons are easy to lose. When the user or maintenance personnel disassemble the computer and the server, there is often no spare spare screw due to the loss of the small size screw, which causes maintenance troubles. SUMMARY OF THE INVENTION [0003] In view of the above, it is necessary to provide a combination screw, which can find the spare screw of the same specification in time when the small size screw is lost. [0004] A combination screw includes a first screw and a second screw having a smaller size Q than the first screw. The first screw defines a receiving hole, and the second screw is received in the receiving hole and The first screw is locked together. [0005] A combination screw includes a first screw and a second screw having a smaller size than the first screw. The first screw defines a receiving hole, and the second screw is received in the receiving hole. It can be used as a spare screw, and the second screw can be used separately from the receiving hole. [0006] The second screw of the combination screw can be locked in the first screw for emergency use, or can be taken out from the first screw separately, avoiding the loss of 098111206 Form No. A0101 Page 3 / Total 10 pages 0982018486-0 201037176 When you lose the small size screw, you can't find the spare screw of the same specification. [Embodiment] Referring to Figures 1, 2 and 3, a preferred embodiment of the combination screw of the present invention includes a first screw 10 and a second screw 20. The first screw 10 is a large-size screw, and the second screw 20 is a small-sized screw. The first screw 10 includes a nut 12 and a threaded screw 14 having an outer surface, the screw 14 and the nut 12 connected into one. The second screw 20 includes a nut 22 and a threaded screw 24 having an outer surface. The screw 24 is integrally coupled to the nut 22. In the embodiment, the nuts 12 and 14 are substantially conical. The second screw 20 is smaller than the size of the first screw 10. The first screw 10 is provided with a receiving hole 16 extending from the nut 12 into the screw 14. The portion of the receiving hole 16 in the nut 12 is substantially conical and can be received. The nut 22 of the second screw 20 is provided with a thread in a portion of the receiving hole 16 in the screw 14, and the screw 24 of the second screw 20 is rotatably locked. Two grooves 122 are symmetrically formed on the upper surface of the nut 12 along the periphery of the receiving hole 16 . In the embodiment, when the second screw 20 is rotatably locked to the first screw 10 , the receiving hole 16 is The central axes of the first screws 10 coincide with each other, and a screwdriver extends into the two grooves 122 to rotatably lock the first screws 10. [0009] The second nut 22 is provided at the center of the second nut 22 and has a cross-shaped slot 222 and a groove 224. When the second screw 20 serves as a spare screw, it passes through the screw 24. The screw is locked in the receiving hole 16 of the first screw 10, and when the first and second screws 10 and 20 are locked together, the screw 24 is received in the portion of the receiving hole 16 in the screw 14. The nut 22 is received in the portion of the receiving hole 16 in the nut 12, each 098111206 Form No. A0101 Page 4 / Total 10 Page 0982018486-0 201037176 [0011] [0012] [0013] Q [0015] The groove 122 is in communication with a corresponding groove 224, so that the first screw 10 can be rotatably locked by using a larger screwdriver into the grooves 122 and 224 without removing the second screw. Screw 20. When the second screw 20 is to be used alone, a smaller size screw can be used to extend into the groove 224, and the second screw 20 is rotatably taken out from the first screw 10. When the second screw 20 in the mechanism device, that is, the screw of a smaller size is lost, the second screw 20 can be taken out from the first screw 10 for use, which facilitates the subsequent maintenance of the mechanism device. 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.
