[0027] The self-locking mechanism includes a self-locking rod 6, which is threadedly connected to the mounting plate 3, and one end of the self-locking rod 6 is against the side wall of the guide rail 2.

The output end of the driving electric cylinder 7 is fixedly connected to one end of the connecting rod 9. The other end of the connecting rod 9 is hinged to the arc frame 8. The arc frame 8 is hinged to the top of the mounting plate 3, and one end of the arc frame 8 away from the connecting rod 9 is fixedly connected to the bracket 4. The connecting rod 9 is driven to move upward by starting the driving electric cylinder 7, and the arc frame 8 can rotate as the connecting rod 9 moves upward, and drives the bracket 4 to move in an arc. The digital video converter box test circuit board is first fixed by a fixing fixture 22, and then the bracket 4 drives the test wire 5 to move and insert it into the slot on the test circuit board for automatic testing, thereby further improving the test efficiency.
