1. the unlocking component used for the invention can be a key, a lock hole with a locking knob rotation function is opened, and the direction-adjusting gear knob can be rotated by opening the lock hole;
2. after a proper position is selected to enable the adjustable magnetic force fixing seat to be tightly attached to the surface of the manhole flange, the direction-adjusting gear knob is rotated to enable a strong magnetic material on the adjustable magnetic force fixing seat to have magnetic force to tightly absorb the manhole flange;
3. pulling the telescopic isolation belt to enable the other adjustable magnetic force fixing seat to be located at a proper position on the other side of the manhole flange;
4. repeating the steps 1-2 to complete the installation of another adjustable magnetic force fixing seat;
5. locking the lockholes with the rotating functions of the two locking knobs by using a key;
6. repeating the steps 1-5 to install another group of the invention which is vertically arranged with the former group;
7. and after the installation is finished, the key is handed to a field manager.
The method is operated according to the following steps when the limited space operation condition is obtained and the method needs to be relieved:
1. the unlocking key is obtained to a field administrator by a limited space operation ticket;
2. the key is used for opening the lock holes with the locking knob rotation function one by one;
3. the direction-adjusting gear knobs are rotated one by one to turn up the strong magnetic materials on the adjustable magnetic force fixing seats, and then the magnetic force fixing seats are disassembled one by one.
The application scenarios of the invention are as follows:
1. the manhole of the container is opened during equipment maintenance, and the container is ventilated and replaced;
2. the operation ticket in the limited space is not approved and completed;
3. a restricted space job interruption period;
