[0016] Combine the following Figure 1~Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0017] like Figure 1 The probe station PCB board quick fixing device shown includes: a fixing seat 1, a rotating pin 11, a threaded pressure rod 8 and a pressure plate 2. The pressure plate 2 is arranged in the fixing seat 1. The bottom of the fixing seat 1 is provided with a first avoidance groove 4 located below the pressure plate 2 to facilitate the probe to test.

[0018] The fixing seat 1 is provided with PCB pads 3 located on both sides of the first avoidance groove 4. The PCB board is first placed on the PCB pads 3, and the two ends of the PCB board are supported by the PCB pads 3, and then the pressing plate 2 is installed. The pressing plate 2 is provided with a second avoidance groove 6 located above the first avoidance groove 4, and various components on the PCB board are avoided by the second avoidance groove 6.

[0019] The rotating pin 11 is rotatably arranged at both ends of the pressure plate 2 and extends downward. In this embodiment, the rotating pin 11 is provided with a retaining spring 10 located above and below the pressure plate 2 to prevent the axial movement of the rotating pin 11 during rotation. A handle 9 is provided on the top of the rotating pin 11, and the rotating pin 11 is rotated by the handle 9, which is easy to operate.
