[0023] When it is necessary to install and fix the fixing plate 201 and the receiving plate 204, the fastening screw 3 is passed through the through hole opened on the receiving plate 204, and then the fastening screw 3 is rotated to connect the fastening screw 3 with the threaded hole opened on the device shell until the receiving plate 204 is tightly fitted with the device shell, and then the pulling handle 503 is pulled to make the pulling handle 503 start to move away from the installation plate 501. Because the first adsorption plate 504 is installed on the pulling handle 503, the first adsorption plate 504 starts to move away from the second adsorption plate 505 until the first adsorption plate 504 is no longer in contact with the second adsorption plate 505, and then the fixing plate 201 is moved towards the receiving plate 204. Because the guide plate 4 is installed on the receiving plate 204, the guide plate 4 starts to The square grooves on the fixed plate 201 fit together, and then the distance between the fixed plate 201 and the receiving plate 204 can be adjusted. When it is adjusted to a suitable position, push and pull the handle 503, and the pulling handle 503 begins to drive the limiting rod 502 to move in the direction close to the guide plate 4 until the limiting rod 502 and the grooves on the guide plate 4 fit together. At this time, the first adsorption plate 504 installed on the pulling handle 503 begins to be adsorbed with the second adsorption plate 505 installed on the additional plate 501 (the first adsorption plate 504 is set as a magnet, and the second adsorption plate 505 is set as an iron ring plate structure, that is, the first adsorption plate 504 and the second adsorption plate 505 start to be adsorbed to each other when they are close to each other).
