After the two adjacent movable plates 26 are moved, the movable plate 26 is released so that the two movable plates 26 are reset and moved respectively under the action of the corresponding No. 2 springs 28, further making the two movable plates The magnets 30 on the moving plate 26 are fitted and adsorbed to each other to complete the limiting and positioning operations of the two horizontal plates 25, and further realize the positioning operation of the vertical plates 36 on the two connecting plates 29, and then repeat the above operations to complete the installation of other horizontal plates 25, vertical plates 36 and other components, then align the card holder 15 with the rotating rod 12, and align the card block 16 inside the card holder 15 with the card slot 13 on the outside of the rotating rod 12, insert the card holder 15 into the outside of the rotating rod 12, realize the connection between the laser rangefinder 14 and the motor 8, and then need to install multiple detection plates 38, at this time, the two card sleeves 37 on the detection plate 38 can be clamped on the outside of the two vertical plates 36 on the same side, after all the detection plates 38 are installed, the motor 8 and the laser rangefinder 14 can be driven by the power supply, and the motor 8 can be used to drive the motor 8 The rotating rod 12 is driven to rotate, and the rotating rod 12 uses the card slot 13 and the card block 16 to drive the card seat 15 to rotate, and the card seat 15 drives the laser rangefinder 14 to rotate, and the laser rangefinder 14 is used to measure the distance from the center position of the mounting seat 3 to the vertical plate 36 and the detection plate 38. The detected data can be integrated later to obtain the position of the internal space of the equipment body 1 to complete the detection work. After the detection, when a series of components are disassembled, the laser rangefinder 14 can be removed from the outside of the rotating rod 12 first, and then the multiple blocks 31 are pulled so that the blocks 31 drive the positioning blocks 34 on the crossbar 32 away from the operating table 2. Then the mounting seat 3 can be removed from the top of the operating table 2 as a whole. The overall disassembly operation is convenient, and when the movable frame 18 and other components need to be cleaned later,The detection plate 38 and the card sleeve 37 can be removed from the vertical plate 36, and then the two adjacent adsorbed magnets 30 are separated, and the horizontal plate 25 is rotated by the circular shaft 24, so that the horizontal plate 25 drives the connecting plate 29 and other components to deflect to the outside, and the multiple horizontal plates 25 are separated and separated from the connecting plate 29, which can provide a larger cleaning space, so that the subsequent cleaning work can be better completed.
