[0046] In the utility model, the working steps of the device are as follows:

[0047] First, use the universal wheel 2 to move the device to the position where the electromechanical device needs to be installed. If the ground is tilted and uneven, you can rotate the spherical shaft 18 along the middle of the positioning plate 15 and observe the bubble level 19. The spherical shaft 18 drives the supporting frame 10 and the bubble level 19 to rotate synchronously.

[0048] After that, the mains electricity can be connected to power the entire device. The user can also choose to install a battery to power the device. Then, the controller 3 is used to start the cylinder 5. The cylinder 5 is a double-acting cylinder with controllable stroke and high precision. The piston end of the cylinder 5 lifts the first connecting frame 6. The telescopic component 4 assists the first connecting frame 6 to rise smoothly. After the first connecting frame 6 drives the components on its upper part to move to a suitable height, the cylinder 5 can be closed. Then, the controller 3 is used to start the first motor 7 and the second motor 9. The first motor 7 and the second motor 9 are both stepping motors with strong controllability and high sensitivity. The output ends of the two groups of first motors 7 drive the two groups of first screw rods 11 to rotate, so that the moving plate 12 moves along the outside of the first screw rod 11. The surface and the outer surface of the first limit rod 13 move, the movable plate 12 drives the upper parts thereof to move, and the specific longitudinal position of the supporting frame 10 can be controlled, and the output ends of the two groups of second motors 9 drive the two groups of second screw rods 14 to rotate, so that the positioning plate 15 moves along the outer surface of the second screw rod 14 and the outer surface of the second limit rod 16, and the positioning plate 15 drives the upper parts thereof to move, and the specific lateral position of the supporting frame 10 can be controlled, until the electromechanical position in the supporting frame 10 reaches the specified position, and then the first motor 7 and the second motor 9 are turned off, and then the cylinder 5 can be started again, and the above steps are followed until the electromechanical is in close contact with the wall, and finally the electromechanical is fixed to the wall using the existing technology.
