The configuration of the first rail portion 211 is a stud, and the center line D1 of each of the first rail portions 211 and the center line L1 of the support member 21 are maintained at an inclination angle θ, adjacent to the first A track portion 211 is spaced apart by a predetermined distance. The card portion 212 is a resilient column, and the position is disposed between the adjacent two first track portions 211, and the bottom end thereof can protrude. The bottom of the first track portion 211.

A recessed slot 220 is defined in the top of the fixed base 22. The fixed base 22 is provided with a plurality of second rail portions 221 corresponding to the inner wall surface of the latching slot 220. The second rail portion 221 is configured. The type is a ring groove, the number of which is matched with the first track portions 211, and the inclination angle θ is also maintained between the center line D2 of the second track portions 221 and the center line L2 of the fixed seat body 22. The adjacent second track portions 221 are also spaced apart by the predetermined spacing. One end of each of the second track portions 221 corresponds to the top of the card slot 220, and the other end extends to the card slot 220. At the bottom of the fixing base 22, a position of the other end of each of the second rail portions 221 is further provided with a stopping portion 222, the number of the stopping portions 222 being equal to the first rail portions 211, and A first inclined wall 222a is disposed on a side edge of the second rail portion 221, The other side edge is provided with a second inclined wall 222b.

Referring to Figures 2 to 5, when the user wants to install the fixing device 2, the bottom side of the fixing base 22 is fixed (for example, locking, sucking, etc.) to a plane, Aligning the first track portions 211 with the second track portions 221 according to the orientation that the bearing 210 is to face, while rotating the support member 21 along the circumferential direction of the support member 21 to make the support The component 21 can be embedded in the card slot 220, and one end of the first track portion 211 will be displaceable along the second track portion 221, and the card portion 212 will be able to abut the first inclined wall. 222a; when one end of the first rail portion 211 is displaced to the other end of the second rail portion 221 to completely engage the second rail portion 221, the clip portion 212 can be deformed to After the first inclined wall 222a is displaced to the position corresponding to the second inclined wall 222b, since the bottom surface of the supporting member 21 abuts against the top surface of the fixing base 22, the supporting member 21 cannot be Continue to rotate, and since the insertion portion 212 is abutted against the second inclined wall 222b, the support element can be prevented 21 by the release of the clamping groove 220.

The fixing device of the present invention can effectively prevent the supporting member 21 from loosening due to the influence of the external force. Referring to FIG. 3, when the fixing device 2 is subjected to an external force, the external force generates a force F to the fixing device 2. The first component force F1 may be subdivided into a first component force F1 and a second component force F2, wherein the first component force F1 is parallel to the direction in which the first track portions 211 are disposed, and the second component force F2 is perpendicular to the first component force F2. The first rail portion 211 is disposed in a direction, and the second component F2 and the force F are maintained at an interval angle φ, that is, the relationship between the first component F1 and the force F is “F1=F”. * sin φ", the relationship between the second component force F2 and the force F is "F2=F* cos φ". If the friction coefficient of the first rail portion 211 is μ, the second component force F2 will form a frictional force on the first rail portion 211, and the direction of the friction force is opposite to the first component force F1. And its size is "μ F2, that is, μ F*cos φ".
