In addition, it can be clearly observed from FIG. 5 that the latch 211 is buckled and positioned in the initial latching groove 125, so that the rotating member 2 will not rotate due to vibration factors.

Please refer to FIG. 6, which shows a top view of the rotating member 2 rotated to an angle relative to the positioning member 1 to show that the holder is in a locked state to the electronic device 4. It can be clearly seen from FIG. 6 that the blocking wing 21 partially shields the supporting recess 122, and the tenon 211 is buckled and positioned in the relay groove 127, which also prevents the rotating member 2 from being affected by vibration. Cause rotation.

Please refer to FIGS. 4 and 7, which show a perspective view and a top view of the rotating member 2 rotated to another angle with respect to the positioning member 1 to show that the holder is also in a locked state to the electronic device 4. It can be clearly seen from FIG. 4 that the blocking wing 21 also partially shields the supporting recess 122. In addition, it can be clearly observed from FIG. 7 that the latch 211 is buckled and positioned in the terminal groove 126, which also prevents the rotating member 2 from rotating due to vibration factors.

As shown in Figures 8-13, which show the first embodiment of the holder, a schematic diagram of the installation process of a plate 3 and an electronic device 4, wherein the plate 3 is implemented as a circuit board, and the electronic device 4 is implemented. It is selected from the circuit board of Wi-Fi wireless network card, 3G network card or M.2 solid state drive. When assembling, the assembly personnel of the assembly plant first align the fixing hook 141 and the pair of elastic hook pieces 142 of the fixing structure 14 of the positioning member 1 into a T-shaped plate hole 31 of the plate 3 and insert (showing In FIG. 8), a pair of the tooth steps 143 of the pair of elastic hook pieces 142 are buckled to the pair of long side edges of the plate hole 31, and the fixing protrusion 144 is clamped into the plate hole 31 In a short side, the positioning member 1 is prevented from causing the problem of incorrect installation, and the positioning member 1 is firmly connected to the board 3 by the fixing structure 14 (shown in FIG. 9).

Then, insert a contact portion 41 at one end of the electronic device 4 into a connector 32 on the board 3; move a positioning recess 42 at the other end down and place it in the supporting recess 122 (shown in the figure) 10 and Figure 12). At this time, the assembler rotates the gripping piece 23 in a counterclockwise direction, so that the blocking wing 21 and its tenon 211, the shaft and its at least one hook 221 also rotate synchronously, so that the at least one hook 221 is in position Rotate in the annular buckle groove 131 of the insertion hole 13 and allow the tenon 211 to escape from the initial groove 125 and pass through the relay groove 127 until it touches a stop flange 121 and buckles into the terminal The card slot 126 allows the blocking wing 21 to partially cover the supporting recess 122, and to sandwich the other end of the electronic device 4 together with the supporting recess 122, so as to form a locking type for the electronic device 4 (shown in the figure) 11 and FIG. 13), and the positioning member 1 is fixed on the board 3, and the electronic device 4 forms a stable positioning effect, except that it will not shake, and can ensure the electronic device and the connector 32 Electrical connection.

Compared with the first embodiment, the second embodiment has the same reference numerals (symbols) used to denote the same components. The second embodiment shares many common components with the first embodiment, so only the differences between the two are described in detail later.

The surface of the fixing hook 141 of this embodiment is not provided with the fixing protrusion 144 of the previous embodiment. Therefore, a plate hole 31 of the plate 3 for the fixing structure 14 to be inserted into is not designed to be foolproof.

Therefore, in this embodiment, at least one outer surface of the fixing hook axially protrudes an auxiliary fixing rib 145. The auxiliary fixing rib 145 can adapt to the tolerance of the plate hole 31 and utilize the auxiliary fixing rib 145 itself. The plastic is elastically deformed to increase the degree of engagement with the plate hole 31 to increase the fixing function.

Therefore, through the implementation of the present case, the gain effect is that the rotating shaft of the rotating member is inserted into the insertion hole of the positioning member, so that the rotating member has the function of rotating relative to the positioning member, and using The tenon is selectively buckled to the terminal slot or the initial slot, and whether the blocking wing covers the supporting recess to lock or unlock the electronic device, which is unprecedented in similar articles One of the great structures.

The disclosure in this case is one of the preferred embodiments. Any partial changes or modifications that are derived from the technical ideas of the case and can be easily inferred by those who are familiar with the art do not deviate from the scope of the patent right of the case.
