It should be noted that: the wireless positioning control host 1115 is in wireless connection with nearby wireless positioning control hosts 1115 through the wireless positioning control host 1115, the isolation rod mechanisms 1 are basically arranged into a straight line, two wireless positioning control hosts 1115 are arranged on two sides of one wireless positioning control host 1115, but the isolation rod mechanisms 1 need to be interconnected one by one, and the wireless positioning control hosts 1115 can detect other wireless positioning control hosts 1115 closest to the wireless positioning control hosts through positioning functions, so that the first wireless positioning control host 1115 can be interconnected with the second wireless positioning control host 1115 only, the second wireless positioning control host 1115 can be connected with other nearby wireless positioning control hosts 1115 which are not in wireless connection, and accordingly connection can be achieved one by one.

It should be understood that: when the second permanent magnet 1413 flies together with the hollow shell 1412 and is magnetically connected with the first permanent magnet 139, the second permanent magnet 1413 and the hollow shell 1412 drive the second flexible wire 1415 to pass through the middle position of the two long rods 157; and the second permanent magnet 1413 and the first permanent magnet 139 are both flexible and strong magnets, so that the second permanent magnet 1413 and the first permanent magnet are prevented from rebounding when the second permanent magnet 1413 collides with the first permanent magnet.

In this embodiment: after the first permanent magnet 139 and the second permanent magnet 1413 are primarily fixed by magnetic force, the wireless positioning control host 1115 needs to control the rechargeable battery 1114 to energize the third driving motor 154, the third driving motor 154 can drive the threaded rod 155 to rotate after being energized, the sliding block 156 can only slide on the inner side of the total support 153 and can not rotate, so the threaded rod 155 can drive the sliding block 156 to move so as to drive the long rod 157 to move, the threaded rod 155 rotates to drive the upper sliding block 156 and the lower sliding block 156 to move oppositely because the thread directions of the upper end and the lower end of the threaded rod 155 are opposite, when the distance between the two long rods 157 is gradually reduced to be smaller than the minimum size of the hollow shell 1412, it can be understood that the hollow shell 1412 is limited by the two long rods 157, so that the hollow shell 1412 can not be pulled back by the second flexible wire 1415, at this time, the wireless positioning control host controls the rechargeable battery 1114 to energize the second driving motor 152, the second driving motor 152 is powered on to drive the main support 153 to rotate, according to the connection relationship, the rotation of the main support 153 finally drives the two long rods 157 to rotate, the long rods 157 rotate to wind the second flexible wire 1415, so that the second flexible wire 1415 is wound, when the second flexible wire 1415 is completely drawn out from the elastic winding wheel 1416, the two long rods 157 are not separated, the second flexible wire 1415 drives the elastic winding wheel 1416 to move, the elastic winding wheel 1416 drives the limit baffle 1314 to move, the limit baffle 1314 drives the warning tape 1313 to be drawn out from the outer side of the winding wheel 1311, so that the winding wheel 1311 overcomes the elastic force of the coil spring 1312 to rotate, and the warning tape 1313 is drawn out.

It should be noted that: when the warning tape 1313 is pulled out, the pulling force of the coil spring 1312 on the winding wheel 1311 needs to be far larger than the elastic force of the elastic winding wheel 1416 on the second cord 1415, the elastic force of the elastic winding wheel 1416 on the second cord 1415 is far smaller than the pulling force generated by flying movement of the hollow shell 1412, and the pulling force of the coil spring 1312 on the winding wheel 1311 cannot affect the stability of the spacer rod mechanism 1 during placement.
