Description of the Invention: [Technical Field to Which the Invention pertains] The present invention relates to a fixing device. [Prior Art·] [0002] Fixing devices are widely used in component assembly processes of electrical equipment, mechanical equipment, and the like. Fixing means, such as screws and nuts, or bolts and nuts, pass through the through holes of the elements to hold the different elements together in a clamping manner. However, the length of most fixtures is fixed. When the through hole depths of the components are different, it is very inconvenient to replace the fixing device suitable for the depth of the through holes. Therefore, there is a need to provide a fixture that can vary in length to accommodate components having different through hole depths. SUMMARY OF THE INVENTION In view of the above, the present invention provides a fixture that secures components having different through-hole depths together. [0004] The fixing device includes an operation portion, a displacement portion, a positioning portion that is rotatably sleeved on the displacement portion, and a catch portion that is accommodated in the displacement portion. The operating portion is used to control the engaging portion to extend and retract into the displacement portion for fixing and unfixing. The positioning portion includes a cylindrical portion, a sliding member slidably coupled to the cylindrical portion, and an elastic member connecting the cylindrical portion and the slider. When the retaining portion projects out of the deforming portion, the sliding member cooperates with the retaining portion to fix the first member to the second member under the elastic action of the elastic member. The cylinder portion defines a sliding slot and a plurality of positioning slots that communicate with the sliding slot. The displacement part sets the displacement hook. The displacement hook can slide along the sliding slot and snap to different positioning slots to adjust the length of the fixing device. [0005] By means of the fixing device, the user can fix the components 099102916 form number A0101 page 4/22 pages 0992005534-0 201128084 with different through hole depths.

Sliding to the middle end portion 424. The two holding portions 40 are extended by the force of the two pull rods 120 to extend out of the guiding hole 314. The external force is cancelled, and the elastic member 230 generates a restoring force to form a sliding force. The workpiece 220 is locked/clamped between the slider 220 and the two latching portions 4A. At this time, the CPU fan 80 is fixed to the main board 90. 099102916 Form No. A0101 Page 9 of 22 Page 0992005534-0 201128084 Just when cp[/fan 8〇 is removed from the motherboard 90, turn the screw to make it pull 120 is slid from the middle end portion 424 of the recess 422 to the end portion 425. The two latching portions 40 are forced into the guide hole 314 by the force of the two pull rods 12 。. At the same time, the elastic member 230 is elastically restored by the elastic force. And further returning to the natural state so that the user can easily take out the fixing device 100 from the first through hole 82 and the second through hole 92. [0020] [0020] Referring to FIG. 7 simultaneously, when the first through hole 82 When the sum of the depths of the second through holes 92 is greater than the sum of the lengths of the cylindrical portion 210 and the large cylindrical portion 310 in the direction of the axis A, the clockwise rotation of the cylindrical portion 210 causes the displacement of the displacement portion 30. The hook 3 2 4 is closed to the chute 218, and the displacement portion 30 is pulled downward along the direction of the shoe core A so that the two holding portions 4 are away from the positioning portion 2〇, and when the displacement hook 324 After the chute 218 is down to the appropriate position, the cylinder portion 21 is rotated counterclockwise to engage the displacement hook 324 to the card slot 2162, thereby changing the length of the fixing device 1GQ, so that the Farming 1GG can be applied to through holes with different depths. By means of the fixing device 1()(), the user can adjust the fixing device according to the depth of the hole of the element to be fixed, and therefore, the fixing device 100 can be applied to elements having different through hole depths.
