[0021] In another embodiment of the present invention: a limit ring 81 is fixedly installed on the inner wall of the top rod 1, the rotating ring 77 is slidably installed in the limit ring 81, and the rotating shaft 82 is arranged in the limit ring 81 and fits with the rotating ring 77; A transmission belt 83 is arranged inside the top rod 1, and a bottom frame 88 is fixedly installed at the bottom end of the top rod 1, a friction wheel 89 is rotatably installed inside the bottom frame 88, the transmission belt 83 is arranged on the friction wheel 89 and the rotating shaft 82, and a friction plate 810 is fixedly installed on the bottom rod 3; The friction plate 810 is inserted into the bottom frame 88 and fits with the friction wheel 89. During the descending process of the top rod 1, the top rod 1 will drive the bottom frame 88 to descend synchronously. At this time, the friction wheel 89 in the bottom frame 88 contacts with the friction plate 810 and rotates. As the friction wheel 89 rotates, it will drive the rotating shaft 82 to rotate through the transmission belt 83. As the rotating shaft 82 rotates, the rotating shaft 82 will drive the wire wheel 84 to rotate, thereby winding the wire 85. At the same time, since the rotating shaft 82 contacts with the swivel 77, the swivel 77 will rotate due to friction. At this time, the swivel 77 will slide in a circle in the limit ring 81. At this time, as the top rod 1 descends, it will move in the direction away from the convex strip 710 until the swivel 77 is separated from the convex strip 710. At this time, the convex strip 710 will no longer restrict the movement of the slide bar 76 and the bottom ring 63. At this time, the bottom ring 63, the middle plate 62 and the top ring 61 can be removed from the top rod 1.

[0022] In another embodiment of the present invention: the inner block 78 is arc-shaped and has a variable diameter; Among them reference Figure 6 , the thickness of the upper part of the inner block 78 is smaller, and the thickness gradually increases downward; when the bulb 5 is replaced, the bottom ring 63 under the middle plate 62 is inserted into the top rod 1, and the slide bar 76 on the bottom ring 63 will be inserted into the top rod 1. At the same time, a limiting groove adapted to the limiting strip 75 is provided on the top rod 1. At this time, when the bottom ring 63 is inserted into the top rod 1, the cooperation of the limiting groove and the limiting strip 75 can prevent the bottom ring 63 from rotating in the top rod 1. When the bottom ring 63 is inserted into the top rod 1, the slide bar 76 will also drive the convex strip 710 to be inserted into the top rod 1. At the same time, the position of the convex strip 710 is as shown in FIG. Figure 6 As shown in the upper opening of the rotating ring 77, the push rod 1 is then moved up. At this time, as the push rod 1 moves up, the friction wheel 89 will rotate due to friction on the friction plate 810, and at the same time, the transmission belt 83 will drive the rotating shaft 82 to rotate. At this time, the rotating shaft 82 will drive the wire wheel 84 to release the wire 85. At the same time, as the rotating shaft 82 rotates, it will drive the rotating ring 77 to rotate. At this time, the rotating ring 77 will rotate counterclockwise to approach the convex strip 710, and when the rotating ring 77 approaches the convex strip 710, the inner block 78 thereon will continuously squeeze the convex strip 710 to make it move downward, until the convex strip 710 pulls the slide bar 76 to move up and down on the bottom ring 63 to the lowest position, at this time, the slide bar 76 will not be able to continue to move downward, and at the same time, the slide bar 76 will pull the bottom ring 63 and the middle plate 62 and the push rod 1 to fit tightly.

[0023] In another embodiment of the present invention: a protrusion is fixedly installed on the surface of the slide rod 76, and a groove is opened on the bottom ring 63, and a return spring is fixedly installed between the top end of the slide rod 76 and the top ring 61; When the slide bar 76 is pulled downward through the convex strip 710, the swivel 77 and the inner block 78, the convex block will move downward in the groove until the convex block contacts the bottom wall of the groove. At this time, the slide bar 76 will pull the bottom ring 63 and the middle plate 62 to fit tightly with the top of the top rod 1. At the same time, when the swivel 77 moves in the opposite direction until the swivel 77 and the convex strip 710 are separated, the return spring will also pull the slide bar 76 to rise and return to its original position.

[0024] In another embodiment of the present invention: two stop blocks 79 are fixedly installed on the inner wall of the top rod 1; When the rotating shaft 82 drives the rotating ring 77 to rotate, until the rotating ring 77 contacts the stop block 79, the stop block 79 will limit the continued rotation of the rotating ring 77, so that the rotating shaft 82 can continue to rotate to drive the wire wheel 84 to rotate for winding or unwinding.

[0025] In another embodiment of the present invention: a rotating rod 73 is rotatably installed in the limit bar 75, the rotating rod 73 penetrates the middle plate 62 and extends into the insertion rod 72, a locking block 74 is fixedly installed on the rotating rod 73, a locking groove is opened on the limit block 71, and the limit block 71 is in an inverted L shape; The slide bar 76 is fixedly mounted with an inserting strip 761, and the rotating rod 73 is provided with a threaded groove 731; When the lampshade 2 is stuck on the top ring 61, the limit block 71 on the lampshade 2 will be inserted into the top ring 61, and the limit block 71 will be stuck on the insertion rod 72. At this time, the locking block 74 will be aligned with the locking groove. When the top rod 1 moves up, as the swivel ring 77 rotates and pulls the convex strip 710 downward, the sliding rod 76 will also drive the insertion strip 761 to move downward, and the insertion strip 761 is inserted into the threaded groove 731. At this time, as the sliding rod 76 drives the insertion strip 761 to move downward, the insertion strip 761 will drive the rotating rod 73 to rotate through the threaded groove 731. As the rotating rod 73 Rotating it will drive the locking block 74 to extend from the insertion rod 72 and insert into the locking groove. At this time, the locking block 74 will limit the upward movement of the limit block 71. At the same time, the lampshade 2 jacketed on the top ring 61 will also be restricted from lateral movement. At this time, the locking block 74 will lock the entire lampshade 2, so that the lampshade 2 is installed on the top ring 61 until the bulb 5 needs to be inspected, and the top rod 1 is lowered. At this time, the height of the top rod 1 drops. As the height of the top rod 1 drops, the lampshade 2, bulb 5, etc. will be directly unlocked to facilitate the staff to quickly check, repair or replace.

At this time, the slip ring 92 will squeeze the shock-absorbing spring 93, and the push rod 1 will be supported by the shock-absorbing spring 93. At this time, the fall of the push rod 1 will not directly fall to the ground and cause damage. At the same time, the vibration of the push rod 1 can be repeatedly moved up and down by the shock-absorbing spring 93 after falling, which can loosen the bottom ring 63, the middle block and the push rod 1 on the push rod 1, and also loosen the lampshade 2 and the top ring 61 to facilitate subsequent disassembly.

[0028] In another embodiment of the present invention: the bottom end of the top rod 1 is threadedly penetrated by the limit screw 94, and a screw groove is provided on the bottom rod 3; The limit screw 94 is tightened so that it is inserted into the screw groove, thereby limiting the movement between the top rod 1 and the bottom rod 3.
