During the rotation of the crank 7, the gear 8 is driven to rotate at the same time. At the same time, the gear 8 drives the sector support plate 5 engaged with it to rotate to the specified position. While the sector support plate 5 is rotating, it drives the tensioning mechanism 9 slidably connected above it to rotate, so as to be able to adjust the position of the flexible printed circuit board installed on the connector 906 and facilitate adjusting the position of the measurement points to be detected on the flexible printed circuit board;

[0042] By manually controlling and holding the holding plate 12 to drive the screw 11 to rotate, by rotating the screw 11 forward or backward, the test assembly 13 is moved to the specified position. Then, by manually pressing the handle on the quick clamp 131, the detector 132 is brought into contact with the surface of the flexible printed circuit board to test it.

[0043] All technical features in this embodiment can be freely combined according to actual needs.

[0044] The above embodiment is a preferred implementation scheme of the present invention. In addition, the present invention can also be implemented in other ways.
