It can be clearly seen from the figures that when the positioning fastener 2 is to be unfastened from the preset first interface card 4 and the preset second interface card 5, the operating portion 2212 of the fastening member 22 is pressed toward the rear side of the base 21 to disengage the fastener 2221 from the fastening groove 2102 of the base 21, and the pivot 24 moves a predetermined distance in the slideway 2101, and then force is applied to make the operating portion 2212 rotate downward with the pivot 24 as the center, and the second elastic member 23 is greatly compressed, and the sliding surface 2215 on the bottom side of the operating portion 2212 slides toward the rear side of the base 21 along the guide bevel edges 2112 of the two side guide plates 211, and the fastening member 22 generates a The preset tilt angle is set to make the push portion 2211 rise upward, so that the preset first interface card 4 is affected by the elastic restoring force of the preset conductive terminal in the preset electrical connector, and the end surface away from the preset electrical connector is tilted, thereby making the first holding end 41 of the preset first interface card 4 rotate upward to separate from the first positioning body 213 and the push portion 2211. After the preset first interface card 4 is separated, force is applied to the operating portion 2212 and pulled backward, thereby driving the first elastic member 2151 in the base 21 to be elastically compressed and deformed, so that the preset second interface card 5 is affected by the elastic restoring force of the preset conductive terminal in the preset electrical connector, and the end surface away from the preset electrical connector is tilted, thereby making the second holding end 51 of the preset second interface card 5 rotate upward to separate from the second positioning body 2142 (such as Fig. 9 As shown in the figure, the preset first interface card 4 and the preset second interface card 5 can be pulled out and removed from the preset electrical connector, and then the force applied to the operating portion 2212 of the latching member 22 and the moving portion 2111 of the two side guide plates 211 is removed, thereby driving the pushing portion 2211, the second elastic member 23, the pivot 24 and the base 21 to return to their original positions, and the buckle 2221 of the latching member 22 is buckled into the buckle groove 2102 of the base 21, so as to achieve the purpose of separating the preset first interface card 4 and the preset second interface card 5.

[0051] In addition, the unlocking cooperation between the positioning fastener 2 and the preset second interface card 5 can also be achieved by pulling the moving portion 2111 on the outer wall of the two side guide plates 211, so that the base 21 is pushed toward the supporting plate 1121, and then the first elastic member 2151 is pushed to form elastic deformation to move the positioning fastener 2 a distance toward the supporting plate 1121. The preset second interface card 5 arranged in the fastener 22 will be separated from the support of the first positioning body 213 and the second positioning body 2142 after the positioning fastener 2 is displaced, so as to achieve the effect of separating the preset second interface card 5.

[0052] The present invention has the following advantages: it provides a structure for quickly positioning and disassembling a plurality of interface cards, which refers to a structure for quickly positioning and disassembling a plurality of interface cards, comprising a structure for utilizing the integrated first positioning body 213 and the second positioning body 2142 provided on the base 21 to abut against the first abutting end 41 and the second abutting end 51 of the suspended ends of the preset first interface card 4 and the preset second interface card 5, and by elastically pushing against the first elastic member 2151 and the second elastic member 23, the base 21, the preset first interface card 4 and the preset second interface card 5 are firmly positioned, and by moving the base 21 and the operating portion 2212, the first elastic member 2151 and the second elastic member 23 can each be elastically compressed and deformed to retreat and tilt up, thereby allowing the preset first interface card 4 and the preset second interface card 5 to be separated from the positioning fastener 2, so as to achieve the purpose of quickly positioning and disassembling the plurality of interface cards of the present invention.

[0053] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
