The outer wall of the fixing blocks 8 has a limit slot 9. The outer wall of the mounting frame 4 is fixedly connected to a mounting base 10. The mounting base 10 is equipped with a spring 11 inside. The end of the spring 11 is connected to a movable block 12. One end of the movable block 12 is fixedly connected to a limit pin 13.

[0026] Preferably, the connection end between the fixed block 8 and the wireless AP module 5 is located inside the embedded groove 7, and the end of the limiting pin 13 away from the movable block 12 is adapted to the size of the limiting groove 9. The wireless AP module 5 can form an elastic engagement structure with the mounting frame 4 through the embedded groove 7, fixed block 8, limiting groove 9, mounting base 10, spring 11, movable block 12, and limiting pin 13.

[0027] In practical use, the movable block 12 is moved by the lever to retract the limiting pin 13, and then the wireless AP module 5 is embedded inside the mounting frame 4, so that one end of the two fixing blocks 8 can be located in an embedding groove 7 respectively. At this time, the two fixing blocks 8 will be symmetrically distributed at both ends of the mounting base 10. Then, by releasing the lever, the limiting pin 13 can be popped out and inserted into the limiting groove 9 under the action of the spring 11, so that the wireless AP module 5 can be conveniently installed inside the traffic signal control body 1.

[0028] It should be noted that the wireless AP module 5 is a UART WiFi module. The wiring terminal of the wireless AP module 5 is connected to the serial port module inside the traffic signal control unit 1. After the connection is established, the wireless AP module 5 can operate normally.

At this time, the two fixing blocks 8 are symmetrically distributed at both ends of the mounting base 10. Then, by releasing the toggle, the limiting pin 13 can be ejected by the spring 11 and inserted into the limiting groove 9, thus facilitating the installation of the wireless AP module 5 inside the traffic signal control unit 1. Then, the wiring terminals of the wireless AP module 5 are connected to the traffic signal control unit. The internal serial port module is connected, and after connection, the wireless AP module 5 can operate normally.
