[0044] After the bed plate is lifted to expose the inside of the box bed, the device is placed in the box bed, when the device is fixed with the box bed, in order to match the box beds of different sizes, the inner supporting structure comprises a pair of first side plates 11, second side plates 12 and four corner plates 13, the corner plate 13 is inserted and matched with the first side plate 11 and the second side plate 12 through the first connecting rod 131 arranged on both sides, the first side plate 11 is rotatably connected with the first screw shaft 111, the second side plate 12 is rotatably connected with the second screw shaft 121, the first connecting rod 131 passes through the first screw shaft 111 and the second screw shaft 121, and the first connecting rod 131 is threadedly connected with the first screw shaft 111 and the second screw shaft 121, by rotating the first screw shaft 111 and the second screw shaft 121 threadedly connected with the first connecting rod 131, the relative position of the corner plate 13 and the first side plate 11 and the second side plate 12 is changed, until the four corner plates 13 are clamped into the four corners of the box bed, so that the box beds of different sizes are matched and fixed, and when the position of the corner plate 13 is adjusted, the contact body 2 and the positioning body 3 are synchronously moved, so that the contact body 2 and the positioning body 3 are located at the middle part of the box bed, the inner side of the first side plate 11 and the second side plate 12 is provided with a third connecting rod 16, the middle body 14 comprises a middle sleeve 141 and an end plate 142 symmetrically arranged at the bottom of the middle sleeve 141, the first side plate 11 and the second side plate 12 are inserted and matched with the end plate 142 through the third connecting rod 16, when the inner supporting structure is adjusted to displace the first side plate 11 and the second side plate 12, the third connecting rod 16 can synchronously move the middle sleeve 141 to ensure that the middle sleeve 141 is located at the middle part of the box bed.

[0045] After the fixation of the box bed inside is completed, the next step is to contact the bottom of the bed plate. Considering that the heights of box beds of different sizes are different, in order to ensure that the small rocker plate 321 away from one end of the bed plate can contact the bottom of the bed plate, the height of the contact body 2 and the positioning body 3 needs to be adjusted. The top of the middle sleeve 141 is rotationally connected with a rotating disc 143, the middle part of the rotating disc 143 is provided with a screw groove 144, the bottom of the bearing plate 21 is provided with a stud 213, the stud 213 is located in the screw groove 144, and the stud 213 is in threaded connection with the screw groove 144.
