[0063] Furthermore, the fixed support body 403 can be a fixed plate or a fixed shell, and a partition is arranged inside the fixed support body 403, the function of the partition is to support and limit the positions of different second limiting elastic components 405 and the plug-in boards, so as to ensure that they can play a role accurately in the process of fixing the carrier board 5; the number of the second limiting elastic components 405 is two, which can provide sufficient elastic force to ensure that the plug-in board is tightly in contact with the plug-in tube at the bottom of the carrier board 5 under normal working conditions, so as to achieve stable fixation; and the two plug-in boards can clamp the carrier board 5 from both sides, which can not only ensure the stability of the carrier board 5, but also ensure that the carrier board 5 will not occur when subjected to external forces The offset or tilt improves the accuracy of the detection process; the limiting slide groove 312 opened on the top of the fixed support body 403 ensures the accurate position of the plug-in board during the fixing process, and the sliding connection of the connecting rod ensures the smooth movement of the plug-in board, thereby ensuring the stability of the carrier board 5 in the fixed state, and reducing the risk of circuit board deviation or damage due to loose fixation; by designing the plug-in structure of two plug-in boards and two plug-in cylinders, the operator only needs to gently push the carrier board 5 to separate one of the plug-in boards from the plug-in cylinder, and then continue to push to easily complete the disassembly process. This design greatly simplifies the fixing and disassembly process and improves work efficiency.

[0064] The fixing device, through the threaded connection between the threaded rod and the threaded seat, and the plug-in connection between the plug-in plate and the plug-in tube, together constitutes a double restriction fixing mechanism for the carrier plate 5:

[0065] Firstly, the first restriction is formed by rotating the threaded rod to make it threadedly connected with the threaded seat; this connection method utilizes the self-locking characteristics of the thread to ensure the stability of the carrier plate 5 in the lateral and longitudinal directions and prevent accidental movement during the detection process. As a mature mechanical fixing method, the threaded connection not only provides a reliable fixing effect, but also facilitates rapid assembly and disassembly, reduces the number of fixings, and thus improves work efficiency; secondly, the second restriction is achieved by plugging two plug-in plates into two plug-in tubes; the design of this plug-in structure enables the carrier plate 5 to be easily fixed without the use of tools, greatly simplifies the fixing and disassembly process, reduces the number of fixings, and thus significantly improves work efficiency and operational convenience.

[0066] With this fixing device, the operator can adjust the horizontal viewing angle of the carrier plate 5 by horizontally rotating the entire fixing frame 2. In addition, by pulling the pull rod 308, the limit plate 309 overcomes the elastic force of the first limit elastic component 307 and moves backward, thereby driving the insertion rod 310 to withdraw from the socket 311. At this time, the rotating roller 301 is in a free state, and the rotating roller 301 can be easily rotated by the rotating shaft 302 and the rotating rod 303, thereby driving the carrier plate 5 installed thereon to flip to the desired angle. After the rotation is completed, the pull rod 308 is released, and the first limit elastic component 307 pushes the limit plate 309 to move forward, so that the insertion rod 310 is reinserted into the socket 311, thereby locking the rotation. The position of roller 301, this design allows the operator to quickly and accurately adjust the viewing angle of the circuit board, significantly improving the efficiency of the inspection work; and, by rotating the threaded rod to disengage it from the threaded seat, the carrier plate 5 loses the first restriction. Next, the operator only needs to gently push the carrier plate 5 to either side of the left or right side, so that the plug-in cylinder at the bottom of the opposite side is disengaged from one of the plug-in boards, and then continue to push the carrier plate 5 to move to either side of the left or right side. At this time, the carrier plate 5 loses the second restriction, and the carrier plate 5 can be easily disassembled. This design greatly simplifies the fixing and disassembly process, reduces the number of fixings, and thus significantly improves work efficiency and operational convenience.
