[0033] The detection fixing device of the embodiment is taken as an example for detecting the camera 5. When the camera 5 is detected, the camera 5 is first clamped with the positioning groove 34, and then the cover plate 41 is rotated. The cover plate 41 abuts against the camera 5 during the rotation process, so that the movable seat 33 descends along the guide groove 311. At this time, the first elastic member 39 is compressed. The cover plate 41 is rotated to the first positioning member 37 and the second positioning member 42 clamped. At this time, the position of the camera 5 is fixed, and the camera 5 abuts against the detection member 23. The detection member 23 detects the camera 5. Through the sliding connection of the movable seat 33 and the guide groove 311, and the setting of the first elastic member 39 between the movable seat 33 and the bottom of the guide groove 311, the movable seat 33 moves along the guide groove 311 during the cover plate 41 applying pressure to the camera 5. The inclination and position deviation of the camera 5 are avoided, and the alignment accuracy of the camera 5 and the detection member 23 is improved. After the first positioning member 37 and the second positioning member 42 are separated, the first elastic member 39 can drive the movable seat 33 to reset, so as to realize the automatic separation of the camera 5 and the detection member 23.

Preferably, the first positioning member 37 is provided with a waist-shaped hole, and a screw penetrates the waist-shaped hole and is connected with the connecting base 31, so that the connection position of the first positioning member 37 and the connecting base 31 can be adjusted. Preferably, the top side of the first positioning member 37 is inclined to form a guide surface, so that during the rotation of the cover plate 41, the second protruding edge 48 of the second positioning member 42 can abut against and move along the guide surface until the first protruding edge 38 abuts against the second protruding edge 48.

[0041] The buckle assembly 4 further comprises a pressing plate 49 connected to the cover plate 41 on the side close to the movable seat 33, i.e. the bottom side of the cover plate 41. The buckle assembly 4 is provided with an avoiding hole 411 corresponding to the position of the positioning groove 34 in the vertical direction, which penetrates the pressing plate 49 and the cover plate 41.
