Description of the invention: [Technical field to which the invention pertains] The present invention provides a fixing device in which a retaining collar having a tight deformation is provided in a receiving pipe body of a fixing device, so that the county ring is used as a blocking receiving pipe body. The internal displacement of the _ component is detached, and has the effect of stable combination, high qualitative, not easy to fall off, and indeed securely fastened. ^ [Prior Art] Press, the general panel (board to board) is locked, which is locked by the screw with the knob, the collar and the screw. The screw and the collar are first fixed on the first panel. Rotate the knob to lock the screw into the second panel, and finally tighten the screw with the tool, so that the first panel and the second panel are locked together, which can be used as a mother machine or other board-to-board Used on the connected plates.

SUMMARY OF THE INVENTION In the light of the above-mentioned deficiencies, the inventors have collected relevant materials, evaluated and considered them through multiple parties, and have been designing such sputum devices through continuous trial and modification through years of experience in this business. The birth of the invention patent. The purpose is to support the inner wall surface of the perforated body of the pipe body, and the _ element system is provided with a slewing end of the upper surface of the fresh body, and the slewing end wire extends downwardly with a ferrule spring. ·Into the perforation 2 (four)' and the end of the shaft with a protrusion (four) perforated outer ribs into the end of the dream of the clothes of the miscellaneous 17 卩 'When reading the collar to find the perforation, the end of the ^ will be inherited The _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The ring can use its metal material characteristics to achieve a stable combination, 7 201000247 = high tightness, no thief, and indeed buckle [implementation] knife text ^ will be compiled in the county section (four) with the figure dry ^ more into the step The money scale solution, turn to the example a, but the details are as follows. '二、三_示' is the invention, the three-dimensional exploded view and the side view of the shouting front, :, 'The fixing device according to the invention has the receiving pipe body =: the emergence of Bo 3 and the stop roll / 啄 τ ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο ο 〇, and the convex machine 1u stands 102 on the inner wall surface of the perforation 10, and the meshing portion 丄2 is provided on the side of the receiving pipe 22 and the inwardly tapered slanting body. 21 purchase Na Nai Shishun 1 series has added (four), shaft 2:::?= bottom-to-direction, there is a larger resistance ring and Wei·21 form an external thread 2U1' and screwed The part 2 3 is on the outer ring surface 2:=::, the second 'and _ is set on the _ element, so that the bottom surface of the ring convex part 101 is in a proper shape 8 201000247 1 'and the resisting part 4 1 The side is provided with a relative deformation and stops the shackle 42' on the splicing portion ^3 and is formed in the inner circle of the sling collar 4 by the screw 2 3 and the external thread 2 31 is deformed to form a stop thread 2 3 The structure on the 1st. As shown in the third, fourth and fifth figures, it is the side of the front and the front of the installation: = side view of the assembly and assembly _^^ when the assembly is in the structure, the support body 1 can be hollow U top surface opening = the screw element 2 of the fine thread 3 is partially aligned with the insertion head end 2 ^, and inserted into the upper and lower ends of the section 3 against the bottom surface of the _ element 2 rotating handle 21 When the pipe is received on the ring convex portion m, the rotating head end 21 can be pressed through the == lower to make the bullet port; the screwing portion (10) of the screwing member 2:; outside: the retaining collar 4 is supported by the receiving pipe The opening of the bottom of the heart is loaded with the 'stop ring 4' which can pass through the screwing portion 2, and is continuously pushed into the surface of the receiving body 1 through the hole 7 〇 You can use the external plus factory hard component 5 to add "=1 heart, the round tube 5! Part of the positive sleeve is placed on the top of the 7 secret reading 5, the tube 51 is squeezed = ^ surface, and then reduced The component 邛10 m sub-Lü 51 squeezing the stop ring 4 is forced to the ring convex 2 to complete the shouting configuration of the present invention. At this time, the collision ===butter shape, the wheel fine gamma and the stop & small The outer diameter of the screw 20130247 is 2 31 outside the screwing portion 23 of the screwing member 2. By the above, when the assembled component is used, the first plate 6 which can press the engaging portion 12 of the receiving pipe body 1 to the outer product is fixedly fixed relative to the locking hole 61 (as shown in the fifth figure). The screwing portion 2 of the screwing member 2 is located on the other side of the locking hole 61 of the first plate 6, and then the first plate 6 is screwed onto the second plate 7 and the first plate 6 is placed on the first plate 6. The fixing device is located in the screw hole 71 of the second plate 7, and then presses the rotating 'head end 21' of the screwing member 2 to make the screw portion 23 touch the screw hole 71, and then rotates the rotating head end. 21, the external thread 2 31 of the screwing portion 2 3 is screwed and fixed correspondingly to the screw hole 71 to achieve the effect that the first plate 6 is tightly positioned on the second plate 7 and does not sway, thereby constituting the present invention. The overall use status. When the first plate 6 is to be disengaged from the second plate 7, it is only necessary to rotate the head end 21 by reverse rotation to make the external thread 2 and the screw hole 71 of the screw portion 2 be separated from each other. The first panel 6 is opened and separated from the second panel 7 and has the advantages of simple loading and unloading and easy operation. The above description _ component 2 of the _ end 2! itself on the outer ring surface for finger rubbing, interference to facilitate the rotation of the screwing element 2 of the accommodating part 2 Η, but also on the rotating head end 2 i The surface concave is provided with various types of grooves 2 12 (such as a word, a cross, a rice word, a hexagonal hole, etc.) for the corresponding hand tool to be docked, and the function only needs to provide the screwing element 2 to rotate the function. And when the fixing wire is limited to the narrow hand-making tool, the 201,000247 can be rotated by the finger to rotate the screwing component 211 conveniently and quickly, so that the replacement action is simple and quick. Moreover, the fixing device of the present invention can be used for fixing and fixing the laminated plate member, and the protruding member (not shown) can be provided on the second plate member 7, and the first plate member 6 and the first plate member are provided. The second plate member 7 is tightly attached to the upper and lower surfaces of the convex & component, and the first plate member 6 and the second member 7 are locked-locked by the element 2. The protruding member can be a spacer for a plate, a central processing It, and other fine components on the circuit board. The positive phase is mainly to provide a variable structure. The material can be a structure with extended properties such as Ming and copper. 'When itself: It can be deformed when squeezed. Please refer to the sixth, to the end of the Ming Dynasty. The collar 4 can be concavely disposed on the two side wall surfaces: the portion 4 1 ' or the resisting portion 41 is designed to be a flat shape: two, i, and the abutting portion 41 can also be a sharp cone Ring groove 4!

Can be _ its metal material f characteristics to achieve the combination of folding, positioning 12 201000247 high, not easy to fall off, and indeed the role of fastening. However, the above description is only a preferred embodiment of the present invention, and thus it is not intended to limit the invention to the invention and the equivalent structural changes of the present specification and drawings. The same is included in the scope of the patent of the present invention and is combined with Chen Ming. As stated on the wire, the fixing device of the present invention can achieve the actual effect, the effect and the purpose, so the present invention is sincerely and practically developed, and is designed to meet the requirements, and the level method is like a cap. The trial committee gave the invention patent of this case as early as possible to protect the inventor's hard work.
