The lifting mechanism 3 is provided with a longitudinal limiting device 4 to bear the stress in the longitudinal direction during transportation to avoid the damage of the actuator 32. According to the vertical limiting device, the vertical limiting device 4 is arranged on the lifting mechanism 3 of the scanning bed upper frame 1, the vertical limiting device is used for bearing impact force in the transportation process, the actuator 32 is not stressed in the transportation process, and the actuator 32 is further protected, so that the actuator 32 can safely, stably and reliably work. The longitudinal direction refers to a vertical direction forming a certain included angle with the horizontal direction. In the prior art as shown in fig. 1, the diagnosis device is easily damaged by impact force during transportation because the longitudinal limiting device is not arranged.
In an embodiment, the longitudinal limiting device 4 includes a first locking mechanism 40 disposed on the front swing link 30 and a second locking mechanism 41 disposed on the rear swing link 31 and adapted to the first locking mechanism 40.
