The in-position action has been completed to improve the accuracy of assembly and alignment, and has the effect of easy operation.

Moreover, when the present invention wants to release the first sheet 2 and the second sheet 3, it only needs to use the pull rod 152 of the driving part 15 of the fixing assembly 1 to rotate 90 degrees, 180 degrees or 270 degrees, and drive the rolling elements 133 to disengage. When the pressing plate 33 is in a released state, the driving part 15 is driven so that the elastic holding part 13 of the fixing assembly 1 does not contact the pressing plate 33, and the other side of the slot 14 can be separated from the inner side of the coupling hole 320. Combining the restriction of the side 321, the first sheet 2 and the second sheet 3 can be taken out upward, thereby completing the release action of the present invention.

The fixing portion 12 of the above-mentioned fixing assembly 1 is preferably through the stop ring 121 to allow the first plate 2 to abut for a positioning, but in actual application, the fixing portion 12 can also be assembled by riveting or snapping. It is combined with the first plate 2 into one body, but there are many ways for the first plate 2 to be positioned on the fixing portion 12, so any structure that can achieve the aforementioned effects should be covered by the present invention. Such simple modification and equivalent structure All changes shall be included in the scope of the patent of the present invention for the same reason, and shall be stated.

Furthermore, the elastic resisting portion 13 of the fixing assembly 1 can be a spring, an elastic arm, or other structures with elastic functions. During the displacement of the rolling element 133, the rolling element 133 may be preferably implemented in a circular shape. , So that the rolling element 133 can smoothly move laterally along the accommodating groove 131 of the elastic resisting portion 13, but in practical applications, this is not a limitation. The rolling element 133 can also be cylindrical or elliptical. Shape or other equivalent structural design, while reducing the contact friction between the rolling element 133 and the inner wall surface of the accommodating groove 131, and improving the stability and smoothness of the rolling element 133 during displacement, so as to ensure the overall use Function and effect.

Moreover, the driving portion 15 of the above-mentioned fixing assembly 1 preferably has a hole 151 penetrating laterally, and a flipping rod 152 is penetrated in the hole 151, so that the flipping rod 152 can be rotated to perform the release operation, but in actual application , The driving part 15 can also be provided with a tooth-shaped riveting surface 153 on the surface to be used as a riveting joint (as shown in the seventh figure), or the driving part 15 can be provided with a cross at the bottom surface (as the ninth As shown in the figure), the drive slot 154 in the shape of a word or a P-shaped screwdriver can be used to insert and rotate a hand tool or electric tool such as a cross screwdriver or a word screwdriver to perform the release operation. However, there are many types and structures of the driving part 15 , It can drive the positioning post 11 of the fixed assembly 1 to rotate axially, so any structure that can achieve the aforementioned effects should be Covered by the present invention, such simple modifications and equivalent structural changes shall be included in the scope of the patent of the present invention for the same reason, and shall be stated.

Therefore, the present invention aims at positioning the rolling element 133 and the elastic element 132 in the accommodating groove 131 at the periphery of the positioning column 11 of the fixing assembly 1, and the fixing part 12 at one side of the positioning column 11 is combined with the first plate 2. When the positioning post 11 of the fixed assembly 1 penetrates into the coupling hole 320 on the mating second plate 3, the rolling body 133 can be squeezed against the elastic element 132 to be elastically deformed. The pressing plate 33 enables the positioning column 11 to insert the card slot 14 into the coupling hole 320 to form a positioning at the periphery of the coupling side. This is its main feature.
