[0032] Working process: When the device is in use, the external power supply is energized. When the size of the circuit board body 7 needs to be adjusted within a fixed range, the drive motor 35 is started, and the drive motor 35 drives the double-threaded rotating rod 36 to rotate. One side of the drive motor 35 is fixedly connected to one side of the hollow mounting shell 31. The rotation of the double-threaded rotating rod 36 drives the outer spirally connected toothed slide plate 37 to move at the same time. The toothed slide plate 37 is slidably connected to the movable limiting groove 34, which has the effect of limiting the movement of the toothed slide plate 37. According to the thread set on the outer side of the double-threaded rotating rod 36, the two toothed slide plates 37 can be moved close to or away from each other at the same time. The two toothed slide plates 37 move at the same time to drive the outer toothed slide plates The gear rotating column 51 rotates, and the two arm shells 53 at the front end approach or move away from each other at the same time, and the two arm shells 53 at the rear end approach or move away from each other at the same time. The angle adjustment component 5 rotates to drive the range adjustment component 6 to rotate. After the angle adjustment is completed, when the length of the range adjustment component 6 moving inside the angle adjustment component 5 is adjusted, the hydraulic cylinder 32 is started, and the hydraulic cylinder 32 pushes the push plate 33 to move. One side of the push plate 33 is fixedly connected to one side of the pull rope 56. The movement of the push plate 33 drives the pull rope 56 to move.

The torque plate 61 drives multiple magnetic columns 65 and the disk 66 to approach at the same time. During this process, the upper and lower disks 66 maintain this attraction, which facilitates the upper end and the disk 66 to remain in the same vertical line. At this time, the adjustment effect of the fixed range is completed, and the electric telescopic rod 2 is started. The electric telescopic rod 2 pushes the bracket frame 38 to move, and the bracket frame 38 drives the angle adjustment component 5 and the range adjustment component 6 approach the circuit board body 7 at the same time, and a rubber block is fixedly connected to the bottom end of the disk 66 to increase the friction between the disk 66 and the circuit board body 7.
