[0036] By snapping the pressing plate 18 into the two slide bars 6 at the mounting frame 5, and then moving the pressing plate 18 upward, the pressing plate 18 is moved to the bottom of the manual test fixture 7, and then the two telescopic blocks 14 equipped with the first springs 15 are squeezed, so that the two telescopic blocks 14 with elastic force can be snapped into the two first fixed plates 13 for preliminary fixing of the pressing plate 18, and then the L-shaped limit plate 20 is snapped into the manual test fixture 7 for further snapping the fixing pressing plate 18, so that the fixing pressing plate 18 is easily assembled by snapping, and then the entire mounting frame 5 is snapped into the top of the flip cover 2, and then the horizontal plate 2 is snapped into place. 1 is inserted into the interior of the mounting frame 5 to lock the mounting frame 5, and then the hand wheel 16 is turned. The hand wheel 16 can drive the double-headed screw 10 to rotate, so that the two third connecting plates 11 on the double-headed screw 10 can move toward each other, so that the positioning blocks 12 on the two third connecting plates 11 are clamped and fixed in the card slots 100 of the mounting frame 5, and then cooperate with the two fixing blocks 8 to position and support the mounting frame 5, which is conducive to assembling the manual test fixture 7 on the mounting frame 5 without using screws, so that the entire PCBA test equipment can be assembled conveniently, saving time and effort, and improving the assembly efficiency of the PCBA test equipment when in use;

[0037] By placing the PCBA board to be tested onto the detection needle plate 4, the PCBA board to be tested will also squeeze the two clamping slides 32 installed with the second spring 33, so that the rubber strips 34 on the two clamping slides 32 can elastically clamp the PCBA board to ensure the stability during the PCBA test. Then, the manual test fixture 7 can be used to drive the pressure plate 18 to move downward so that the PCBA board can be pressed onto the detection needle plate 4 for connection testing, which is used to detect the voltage, current and other parameters of the wireless keyboard PCBA board and judge the electrical performance of the wireless keyboard PCBA board. Then, the four first clamping plates 26 can be used to clamp and fix the detection needle plate 4, and then the four rotary plates 27 are respectively moved so that the rubber pressure block 28 at the rotary plate 27 can be positioned above the detection plate 3. At the same time, the two second clamping plates 30 will also be clamped to the top of the detection plate 3 for firmly positioning the detection plate 3, so that the detection plate 3 and the detection needle plate 4 can be flexibly and conveniently clamped and fixed, thereby improving the flexibility of the use of the wireless keyboard PCBA testing equipment.
