[0018] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A lying board for automobile maintenance includes a base 1, the lower end of the base 1 is fixedly connected to a wheel frame 11, the inner part of the wheel frame 11 is rotatably connected to a wheel 12, the upper end of the base 1 contacts a top plate 2, the inner lower end of the base 1 and the lower end of the top plate 2 are hinged with a connecting rod 3 through a hinge frame, and the ends of the two connecting rods 3 close to each other are hinged with a connecting sleeve 31 through a hinge frame, the inner part of the base 1 is rotatably connected to a rotating rod 32, and the outer side of the rotating rod 32 is provided with positive and negative threads. The rotating rod 32 is threadedly connected to the connecting sleeve 31. Through the design of the rotating rod 32, the two connecting sleeves 31 can be driven to move at the same time.

[0019] Please refer to Figure 2 、 Figure 3 、 Figure 4 The outer side of the rotating rod 32 is fixedly connected with a baffle 33, and the baffle 33 contacts the inner wall of the base 1. The design of the baffle 33 can limit the rotating rod 32. The two ends of the rotating rod 32 are fixedly connected with knobs 34, and the knob 34 contacts the base 1. The design of the knob 34 can facilitate the rotation of the rotating rod 32. A slide groove 35 is provided inside the base 1, and the rotating rod 32 is movably connected to the inside of the slide groove 35. The design of the slide groove 35 can make the rotating rod 32 slide inside the base 1, and the front and back of the base 1 are in contact with the guard plate 4.

[0020] Please refer to Figure 2 、 Figure 3 、 Figure 4 The interior of the guard plate 4 is connected to a threaded rod 41 through a bearing, and the threaded rod 41 is connected to the base 1 through a thread. The end of the threaded rod 41 away from the base 1 is fixedly connected to a knob 42, and the knob 42 contacts the guard plate 4. The side of the guard plate 4 close to the base 1 is fixedly connected to a slide rod 43, and the slide rod 43 is slidably connected to the base 1.
