The first driving mechanism is disposed on the guide slider 4, and the first driving mechanism drives the two second bed boards 10 to perform horizontal telescopic movement at both ends of the first bed board 9 through the guide slider 4; A further implementation method is as follows: the first driving mechanism includes an electric push rod 11 and a traction rod 12, and each component is specifically arranged as follows: The electric push rod 11 is fixedly connected to the guide slider 4. The electric push rod 11 is set on the base frame 1 through a mounting bracket. It should be noted that the mounting bracket is a necessary accessory for installing the electric push rod 11. The mounting bracket is composed of a U-shaped clip and a fixing pin. The U-shaped clip and the base frame 1 are fixedly connected. This accessory allows the two ends of the electric push rod 11 to rotate freely, and the protective tube of the electric push rod 11 will not be unable to move due to the base frame 1. The need to use a mounting bracket during the fixed installation of the electric push rod 11 is an existing well-known technology; The traction rod 12 is connected between the guide slider 4 and the second bed board 10. The upper end pin of the traction rod 12 is connected to the second bed board 10, and the lower end pin of the traction rod 12 is connected to the guide slider 4. The upper end of the traction rod 12 is restricted in the vertical direction by the second bed board 10, and the lower end of the traction rod 12 is restricted in the vertical direction by the guide slider 4, so that both ends of the traction rod 12 can only perform linear motion in the horizontal direction. When one end of the traction rod 12 undergoes linear motion, the other end of the traction rod 12 will also undergo linear motion, so that when the guide slider 4 moves, the second bed board 10 will also extend horizontally, which helps to increase the use area of ​​the electric stretcher bed, so that the electric stretcher bed can adapt to patients of different body shapes, and helps to improve the applicability of the electric stretcher bed. The second driving mechanism is arranged on the base frame 1, and the second driving mechanism supports the first bed board 9 through the sliding plate 6 to adjust the height; A further implementation method is as follows: the second driving mechanism includes a mounting slide 13, a motor 14, a ball screw 15, a nut 16, a driving slider 17, a connecting rod 18 and a driving rod 19, and each component is specifically arranged as follows: The mounting slide 13 is provided on the base frame 1; The motor 14 is fixedly mounted on the base frame 1; The ball screw 15 is fixedly connected to the output end of the motor 14.
