The diameter of the circular groove is greater than the length of the support rod 89 to prevent the support rod 89 from being damaged by pressure.

[0035] Working principle: By pressing the cylinder 85, the rotating ring 84 is driven to move downward, so that the circular plate 83 moves downward, so that the fourth spring 82 is compressed, and at the same time, the rotating ring 84 moves downward, and the limiting column 86 is driven to move downward. By rotating the cylinder 85 during the downward movement, the rotating ring 84 rotates, so that the limiting column 86 rotates, so that the inclined surface of the limiting column 86 contacts another inclined surface on the cylinder 87. When the limiting column 86 enters the inclined surface contacting the limiting groove 810, the pressure on the cylinder 85 is released, so that the fourth spring 82 is released, driving The circular plate 83 moves upward, causing the rotating ring 84 to move upward, driving the limiting column 86 to enter the limiting groove 810, causing the cylinder 85 to move upward. Since the limiting column 86 enters the limiting groove 810, the cylinder 85 moves to a higher position. At this time, the support rod 89 passes through a through groove 88 close to the sleeve 2, so that the height of the cylinder 85 changes. At this time, the electric telescopic rod 3 is started to move downward, so that the output end of the electric telescopic rod 3 contacts the plurality of second inclined blocks 64, so that the plurality of second inclined blocks 64 respectively enter the plurality of second inclined blocks 64 one by one. The second springs 65 are compressed in the installation groove 21, and the second inclined block 64 moves to drive the connecting member 63 to move, so that the first inclined blocks 61 are received in the installation grooves 21, so that the first springs 62 are compressed, so that the sliding rod 4 is no longer clamped, so that the sliding rod 4 falls, and the environmental monitoring component 5 moves downward, so that the cylinder 85 passes through the through hole 522, and the cylinder 85 contacts the first movable rod 54, driving the first movable rod 54 to move, so that the first telescopic member 53 contracts, driving The first limiting rod 55 moves, so that the second telescopic members 56 are released, and the first cross bar 57 is driven to move, so that the driven rod 58 is moved, so that the clamping block 59 is released from the clamping groove in the door 52, so that the door 52 can be opened, and then the cylinder 85 contacts the second movable rod 516, so that the second movable rod 516 moves, driving the connecting rod 515 to move, so that the first abutting rod 512 and the transmission rod 513 move synchronously, driving the second limiting rod 514 to move, so that the two third telescopic members 510 The second lever 518 is retracted and the second lever 519 is retracted, so that the third springs 73 are released, and the connecting plates 74 are moved to fit with the stoppers 71, so that the two clamping members 75 are moved, and the two third inclined blocks 76 are moved, so that the two clamping members 75 are released from the dust cover 520. When the cylinder 85 is not raised, the cylinder 85 is only in contact with the first movable rod 54, so that the box door 52 can be opened, and the dust cover 520 will not be disassembled. When the inspection is completed, the box door 52 can be closed. At the same time, when replacing the dust cover 520, the new dust cover 520 is placed in the installation opening 523. Then, the electric telescopic rod 3 is started to drive the sliding rod 4 to move, so that the cylinder 85 is no longer in contact with the first movable rod 54 and the second movable rod 516.The first telescopic member 53, the second telescopic members 56, the two third telescopic members 510 and the fourth telescopic members 517 are released and reset, so that the first abutting rod 512 and the second abutting rod 519 contact the two third inclined blocks 76 one by one, respectively, so that the two third inclined blocks 76 move, drive the two clamping members 75 to move, so that the several connecting plates 74 move, drive the several third springs 73 to be compressed, so that the two clamping members 75 are clamped with the dust cover 520, and the replacement of the dust cover 520 is completed. At the same time, due to the reset of the several second telescopic members 56, the clamping block 59 enters the clamping groove to complete the clamping of the box door 52. When the rod 4 moves upward, it first contacts with the second inclined blocks 64, so that the second springs 65 are compressed, driving the connecting members 63 to move, so that the first inclined blocks 61 are moved and received in the installation slots 21. When the sliding rod 4 moves upward to contact with the first inclined blocks 61, the first springs 62 and the second springs 65 are compressed. When the sliding rod 4 no longer contacts with the first inclined blocks 61, the first springs 62 and the second springs 65 are released, so that the first inclined blocks 61 and the second inclined blocks 64 extend out of the installation slots 21, driving the first inclined blocks 61 to contact with the bottom of the sliding rod 4, so that the sliding rod 4 is locked.
