[0025] The fixing assembly includes a rotating cavity 14 opened in the protective shell 1, and a rotating rod 15 is rotatably connected to the inner wall of the rotating cavity 14.

The two fixing blocks 17 are each provided with a mounting groove. The circuit board 4 slides in the two mounting grooves. The two threaded rods 16 are threadedly connected to a clamping block 18. The two clamping blocks 18 slide through the protective shell 1. The two clamping blocks 18 respectively slide through the two fixing blocks 17 and are installed on the circuit board 4. One end surface of the clamping block 18 is provided with an anti-slip texture, which improves the friction between the clamping block 18 and the circuit board 4 and improves the stability of the circuit board 4;

The two driving wheels 19 correspond to the two driven wheels 20 one by one. Each pair of driven wheels 20 and the driving wheel 19 is driven by a transmission belt 21. A transmission rod is rotated through the protective shell 1, and one end of the transmission rod is fixedly connected to one of the threaded rods 16. A knob 23 is fixedly connected to the transmission rod, which is convenient for the user to rotate the transmission rod, thereby improving the portability of the device.
