[0043] Furthermore, by Figure 1 and Figure 2As shown, in this embodiment, the positioning frame 1 is movably disposed on the top of the detection seat 5, the movable clamping plate 6 is movably disposed on the top of the detection seat 5, two fixed clamping plates 7 are symmetrically fixed to the top surface of the detection seat 5, the control mechanism 8 is drivably connected to the movable clamping plate 6, and is used to drive the movable clamping plate 6 to move so as to cooperate with the fixed clamping plate 7 to clamp the mobile phone motherboard, two limiting blocks 9 are symmetrically fixed to the top surface of the detection seat 5, the second guide rod 10 is fixed between the two limiting blocks 9 and passes through the positioning frame 1, and the manual bolt 12 is installed on the positioning frame 1 by thread engagement. With the above scheme, when in use, the mobile phone motherboard is placed on the top surface of the detection seat 5, and then the control mechanism 8 is used to drive the movable clamping plate 6 to move so as to cooperate with the fixed clamping plate 7 to clamp the mobile phone motherboard, and the manual bolt 12 is loosened. To locate the mobile phone motherboard testing interface, slide the positioning frame 1 along the second guide rod 10, moving the interface guide sleeve 2 to the position directly opposite the mobile phone motherboard testing interface. Then tighten the manual bolt 12 to lock it in place. Finally, pass the terminal of the mobile phone motherboard test harness through the interface guide sleeve 2 and connect it to the mobile phone motherboard testing interface to perform testing on the mobile phone motherboard. In subsequent testing, there is no need to adjust the position of the positioning frame 1 for mobile phone motherboards of the same specifications, improving testing efficiency.
