[0039] The working principle of the charging chip testing device provided by this utility model is as follows: Pulling the positioning rod 211 causes the spring 212 to stretch, and the positioning rod 211 will be pulled out from the adjustment hole 209. At this time, the fixing effect on the fixing plate 203 can be released. The fixing plate 203 is pushed through the adjustment groove 204. The movement of the fixing plate 203 will cause the contact groove 210 on the protective plate 207 to slide on the guide plate 208. At this time, the protective plate 207 will move towards the control panel 5. The coil spring 206 installed on the rotating rod 205 will contact the protective plate 207 with the abutment block 217 installed on the control panel 5 through the movement of the fixing plate 203. At this time, the positioning rod 211 will move into another adjustment hole 209, and the positioning rod 211 can be released. The spring 212 can drive the positioning rod 211 to connect with the inner wall of the adjustment hole 209. At this time, the fixing plate 203 can be moved again, so that the protective plate 207 can be fixed to one side of the control panel 5.

[0040] Make contact between the mounting plate 31 and the bottom of the tester 1. Then, push the locking block 33 out from the connecting frame 32. At this time, the inner wall of the mounting plate 31 can be aligned with the inner wall of the tester 1. Then, the mounting block 36 can be rotated inside the mounting plate 31 to fix the mounting plate 31 to the bottom of the tester 1. This will fix the friction pad 34 to the bottom of the tester 1 and improve the friction of the bottom of the tester 1.
