Description of the Invention: [Technical Field] [0001] The present invention relates to a fixing device, and more particularly to a fixing device which is easy to install and disassemble. [Prior Art] [0002] A fixing device is generally used to connect a first mounting member and a second mounting member, wherein each mounting member is provided with a mounting hole, and the fixing member passes through the mounting holes of the two mounting members. Lock the mounting together. In the prior art, the structure for fixing the two mounting members is usually combined with a nut by a screw. The screw typically has a head that is larger than the mounting hole in the first mounting member and a screw having an external thread. The periphery of the nut is larger than the mounting hole on the second mounting member, and the nut has an internal thread that can be engaged with the external thread of the screw. When installed, the first mounting member is attached to the second mounting member, and the mounting holes thereon are aligned with each other. The nut is stopped against the bottom of the first mounting member. The screw of the screw sequentially passes through the mounting holes of the second mounting member and the first mounting member and is gradually screwed into the nut. When the head of the screw is pressed against the surface of the second mounting member, the first fixing member is fixed to the second fixing member. However, in this fixing manner, the head and the nut of the screw respectively expose the surfaces of the first mounting member and the second mounting member, thereby increasing the thickness of the product. Moreover, when the fixing hole on one of the mounting members is not a through hole, the fixing can not be achieved by such fixing. SUMMARY OF THE INVENTION [0003] In view of the above, it is desirable to provide a fixture that is easy to install and disassemble and that can be used with different types of mounts. [0004] A fixing device for fixing a first mounting member to a second mounting 098121274, Form No. A0101, Page 3 / 13 pages 0982036180-0 201100651, the fixing device comprising a first fixing member and a a second fixing member, the first fixing member has two partitioning portions, the inner wall of the two fixing portions is provided with an internal thread, and the outer wall of the second fixing member is provided with an external thread, and the second fixing member is received in the second fixing member Between the two fastening portions, the external thread of the second fixing member and the internal thread of the two fastening portions of the first fixing member bite to force the two fastening portions to expand outward. [0005] Preferably, the two fastening portions of the first fixing member have a circular arc shape, and the two fastening portions collectively form a cylindrical outer contour. [0006] Preferably, the first fixing member defines two slots extending in the axial direction of the cylindrical outer contour, and the fixing portion is partitioned by the two slots. [0007] Preferably, the two slots are symmetrically disposed on the cylindrical outer contour. [0008] Preferably, the first fixing member has a stopping end connected to the two fastening portions, and the outer wall of the two fastening portions is provided with an external thread, and the external threads of the two fastening portions are close to the blocking end. The nominal diameter of one end of the portion is greater than the nominal diameter of one end away from the stop. [0009] Preferably, the nominal diameter of the external thread of the second fixing member is substantially equal to the nominal diameter of the internal thread of the two fixing portions near the end of the stopping end. [0010] Preferably, the stopping end of the first fixing member is locked to the surface of the first mounting member. [0011] Preferably, the second mounting member is provided with a mounting hole, and the external thread of the second fixing member engages with the inner wall of the mounting hole. [0012] Compared to the prior art, the fixing device of the present invention is screwed into a first fixing member having an internal thread by a second fixing member having an external thread, the second fixing member 098121274 Form No. A0101 Page 4 of 13 Page 0982036180-0 201100651 Forcing the two fastening portions of the first fixing member to expand and deform and engage with the second mounting member to fix the first mounting member and the second mounting member together. The fixture of the present invention is simple in construction and is suitable for fixing different types of mounting members. [Embodiment] [0013] Referring to Figures 1 and 2, the fixing device 100 of the present invention is used to fix a first mounting member to a second mounting member. In this embodiment, the first mounting member is a circuit board 10, and the second mounting member is a base 30. A first mounting hole 11 is defined in the circuit board 10. The base 30 has a base plate 31 and a fixing post 33 protruding from the base plate 31. A second mounting hole 331 is defined in the fixing post 33 corresponding to the first mounting hole 11. In the present embodiment, the fixing post 33 is a plastic piece. A preferred embodiment of the fixture 100 of the present invention includes a first fastener 50 and a second fastener 70. [0014] The first fixing member 50 has a circular stop portion 51. Two opposite fastening portions 53 are formed extending from the bottom of the stopping portion 51. The two fastening portions 53 have a circular arc shape and collectively form a cylindrical outer contour. The cylindrical outer contour defines two slits 55 extending in the axial direction thereof to partition the two retaining portions 53, and the two slits 55 are symmetrically disposed along the cylindrical outer contour. A fixing hole 57 that penetrates the stopper portion 51 is formed between the two fastening portions 53. The inner wall of the fixing hole 57 is provided with an internal thread 531. The outer walls of the two fastening portions 53 are provided with external threads 533. The outer diameter of the outer thread 533 near the end of the stop portion 51 is larger than the nominal diameter away from the end of the stop portion 51. The nominal diameter of the outer thread 533 near the end of the stop portion 51 is slightly larger than the inner diameter of the second mounting hole 331 of the base 30. The second fixing member 70 can be a normal screw or a headless screw. The second fixing member 70 has a locking post 71 provided with an external thread 73. The locking column 71 098121274 Form No. Α0101 Page 5 / Total 13 page 0982036180-0 [0015] 201100651 The nominal diameter of the external thread and the internal thread of the two fastening portions 53 are close to the nominal diameter of the end 51 of the locking end 51 equal. [0018] [0018] 00121274 Please refer to FIG. 3 and FIG. 4 simultaneously, when the fixing device 100 is used to fix the circuit board 10 to the base 30, firstly, the two fastening portions 53 of the first fixing member 50 are worn. The circuit board is inserted into the first mounting hole 11 away from the 10 and inserted into the second mounting hole 331 of the base 30. The stopper portion 51 of the first fixing member 50 is pressed against the top of the circuit board 10. The external threads of the locking post 70 of the second fixing member 70 are screwed along the internal threads 531 of the two fastening portions 53. Since the outer diameter of the outer end of the two locking portions 53 is close to the nominal diameter of the end of the stopping portion 51, the second fixing member 70 is screwed into the first fixing. During the fixing hole 57 of the member 50, the two fixing portions 70 of the second fixing member 70 are gradually forced to expand outward. When the second fixing member 70 is completely screwed into the fixing hole 57, the external thread 533 of the fixing portion 53 is pressed tightly with the inner wall of the fixing post 33 of the base 30, thereby fixing the circuit board 10 to the base. Above 30. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only the preferred embodiment 1 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.
