The lifting assembly is used to realize the lifting and lowering of the support frame, and at the same time, during the lifting process, the support frame is ensured to remain parallel to the inner bottom frame, and the dumping problem will not occur during the lifting process. The inner bottom frame is located inside the outer bottom frame and is connected through a weighing sensor, so that the weight of the patient on the support frame can be detected in time. The inner bottom frame and the outer bottom frame are set in a parallel state. The bed frame and the inner bottom frame form the main body, which are connected with the outer bottom frame through a weighing sensor to ensure the accuracy of weighing.
