The connecting rod 701 serves to connect the two support platforms 4. When the connecting rod 701 hinders the inspection, the connecting rod 701 can be manually moved left and right. Before moving the connecting rod 701, it is necessary to pinch the two pressing blocks 707, the push plate 709 leaves the support platform 4 and unlocks the connecting rod 701, and then the connecting rod 701 can be moved directly. When the connecting rod 701 passes between the upper and lower supporting blocks 6021, the movable frame 6026 is pressed and moved, and the latch 6024 moves and unlocks the supporting block 6021, so that the connecting rod 701 can smoothly pass between the upper and lower supporting blocks 6021.
