The elastic member 300 has a lower end 301 of the elastic member sleeve, as shown in the figure, abutting against the stopping portion 201 of the elastic member sleeve 200 . The mooring screw 400 is attached to the elastic member 300, the elastic member sleeve 200 and the mooring screw sleeve 100. The mooring screw 400 has a threaded portion 401, which protrudes from the mooring of the mooring screw sleeve 100 as shown in the figure. The lower end edge 101 of the screw sleeve and the head 402 are against the upper end 302 of the elastic member of the elastic member 300 , and the head 402 has an upper end edge 403 of the mooring screw, which extends outward and abuts against the contact portion of the mooring screw sleeve 100 . Fix the upper edge 102 of the screw sleeve. The knob part 500 covers and fixes the upper end edge 102 of the mooring screw sleeve of the mooring screw sleeve 100 and the upper end edge 403 of the mooring screw of the mooring screw 400 . The knob part 500 further includes a plurality of concave-convex parts 501 , and the concave-convex parts 501 are located on the outer periphery of the knob part 500 .

FIG. 4 shows the structural relationship of the mooring fixture 10 when the elastic member 300 is in a relaxed state. As shown in the figure, when the mooring fixture is not used to fix the first circuit board and the second circuit board, the lower end edge 101 of the mooring screw sleeve of the mooring screw sleeve 100 is against the outward of the elastic member sleeve 200 The upper end edge 202 of the extended elastic member sleeve. The elastic member sleeve 200 partially protrudes from the lower end edge 101 of the mooring screw sleeve of the mooring screw sleeve 100 .

When a downward force is applied to the mooring fixture 10, the mooring screw 400 is rotated by aligning the groove on the upper surface of the mooring screw 400 with a tool, or the concave-convex portion 501 of the knob member 500 is directly exerted force to rotate the mooring screw 400. Rotating the knob part 500 will simultaneously exert downward force to compress the elastic member 300, and the mooring screw 400 originally located in the mooring screw sleeve 100 and the elastic member sleeve 200 is forced and activated The lower portion of the elastic member sleeve 200 protrudes downwardly. More specifically, the threaded portion 401 of the mooring screw 400 protrudes from the lower end 203 of the elastic member sleeve of the elastic member sleeve 200 . That is, the threaded portion 401 of the mooring screw 400 is pushed out of the lower end 203 of the elastic member sleeve of the elastic member sleeve 200, and then locked on the second circuit board with the corresponding opening facing the threaded portion 401 of the mooring screw 400, so as to fix the first circuit board to the second circuit board. Conversely, if the mooring screw 400 is reversely rotated, or the knob part 500 is reversely rotated, the threaded portion 401 can be released from the second circuit board. The threaded portion 401 of the anchor screw 400 is retracted into the lower end 203 of the elastic member sleeve of the elastic member sleeve 200 to separate the first circuit board from the second circuit board.

In addition, the mooring screw sleeve 100 of the present invention is a stamping or injection molding component, so the cost can be greatly reduced. The knob part 500 of the present invention is an injection-molded component, which can cover and fix the mooring screw sleeve and the mooring screw in one step.
