Specifically, the load-bearing block 9 on the bearing plate 8 supports the main board body 2, and then the rotating block 15 is rotated to drive the worm 10 to rotate in the support plate 3. When the worm 10 rotates, it will drive the worm wheel 11 to rotate accordingly. At this time, the worm wheel 11 is The rotating rod 12 will rotate synchronously. When the rotating rod 12 rotates, the first gear 13 installed thereon will engage with the second gear 14 to realize the rotation of the threaded rod 5 in the vertical plate 4. Because the threaded rotation directions at both ends of the threaded rod 5 are set in opposite directions, when the threaded rod 5 rotates, the movable plates 6 on both ends will move relatively to realize the movement of the L-shaped clamping plate 7.
