When the locking opening 15 is rotated to the same orientation and the opening orientation of the docking groove 13 is the same, such as the bottom and rear side of the docking groove 13 being open in this application, when the orientation of the locking opening 15 is rotated to the rear, the pressing fastener 10 can be pushed forward to unlock, and the support rod at the top of the pressing fastener 10 is released from the locking fastener of the camera module 4. When the locking openings 15 of the two locking blocks 14 are oriented differently, the pressing fastener 10 can maintain the locked docking with the fixture base 1.
[0028] To facilitate the rotation of the locking block 14, two knobs are provided on the surface of the pressing fastener 10. The two knobs are fixedly connected to the rotating shaft of the locking block 14, making it easy to rotate the two locking blocks 14. To position the rotation of the two locking blocks 14, mounting slots 17 are provided at the top of the mating groove 13 and on both sides of the rotating shaft of the locking block 14. A compression spring 18 is provided inside each mounting slot 17, and a positioning ball 19 is fixedly connected to the bottom of the compression spring 18. Positioning grooves 20 are provided on both sides of the top of the locking block 14. The compression spring 18 presses the positioning ball 19 into the positioning groove 20, so that the locking block 14 can be positioned once every half turn.
[0029] Sensor module 5 is snapped into the rear end of snap-fit groove 3. Camera module 4 is installed inside snap-fit groove 3. Press-fit fastener 10 is locked onto locking post 12 via snap-fit block 14. The locking mechanism 11 fixes camera module 4 inside snap-fit groove 3 via press-fit fastener 10. The connection window 8 on docking protective plate 2 is moved into docking gap 6 to perform imaging detection on camera. When replacing camera module 4, docking protective plate 2 is moved until protective plug 9 is inside docking gap 6 to protect sensor module 5.
[0030] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
