The plurality of groups of second sleeves 13 are hollow cylindrical and are sleeved together in sequence and are concentric with the first sleeve 4 and the first threaded rod 8. A fixing ring 5 is fixedly disposed on the upper end surface of the second innermost sleeve 13; The bottom of each of the second sleeves 13 sequentially matches with the threads provided at the screw rod portion of the first threaded rod 8; A guide assembly is provided between the plurality of groups of the second sleeves 13, for guiding each of the second sleeves 13 to be raised and lowered one by one; The guide assembly includes a second guide groove 17, and the second guide groove 17 is provided on the first sleeve 4 and on the inner wall of multiple groups of the second sleeves 13 between the first sleeve 4 and the innermost second sleeve 13; A first guide block 23 is provided at a position of the second sleeve 13 corresponding to the second guide groove 17. The first guide block 23 is slidably arranged inside the second guide groove 17, and the top ends of the inner walls of the plurality of groups of the second guide grooves 17 are all provided with first receiving grooves 18. A clamping block 19 is inserted inside the first receiving groove 18. The lower end surface of the outer side of the clamping block 19 is in the shape of a beveled surface, and a first elastic member 20 is provided between the first receiving groove 18 and the clamping block 19. The clamping block 19 is elastically inserted into the first receiving groove 18 through the first elastic member 20. The distance between the top of the second guide groove 17 and the top of the first receiving groove 18 matches the size of the first guide block 23. It also includes a release member, which is used to release the restriction of the first guide block 23 by the clamping block 19; The release member includes a third receiving groove 28, which is provided on the lower end surface of one end of the second sleeve 13 corresponding to the first threaded rod 8, and a second abutting block 27 is inserted in the third receiving groove 28, and a third elastic member 29 is provided between the second abutting block 27 and the third receiving groove 28, and the second abutting block 27 is elastically inserted in the third receiving groove 28 through the third elastic member 29; A first through hole 22 is provided between each of the first receiving grooves 18 and each corresponding third receiving groove 28, a first pull rope 21 is provided inside the first through hole 22, two ends of the first pull rope 21 are respectively connected to the second abutting block 27 and the clamping block 19, and the elastic force of the first elastic member 20 is greater than the elastic force of the third elastic member 29; A second receiving groove 24 is provided at a position of the first threaded rod 8 corresponding to the innermost second sleeve 13, a first abutting block 26 is inserted in the second receiving groove 24, a second elastic member 25 is provided between the second receiving groove 24 and the first abutting block 26, the first abutting block 26 is elastically inserted in the second receiving groove 24 through the second elastic member 25, and the elastic force of the second elastic member 25 is greater than the elastic force of the first elastic member 20, so as to limit the first guide block 23 to abut against the lower end surface of the clamping block 19 and lift the corresponding second sleeve 13; The cable is installed inside the fixing ring 5, and then the first threaded rod 8 is driven to rotate. When the first threaded rod 8 rotates, due to the limiting cooperation of the first sleeve 4 and the first guide block 23 and the second guide groove 17 arranged between the first sleeve 4 and the second sleeve 13, the innermost second sleeve 13 will rise along the first threaded rod 8, and the corresponding first guide block 23 will slide along the second guide groove 17 opened on the inner side of the adjacent second sleeve 13. When the innermost second sleeve 13 rises to a certain height, it will squeeze the elastically arranged block 19, and then the adjacent second sleeve 13 will be driven to rise along the first threaded rod 8 through the cooperation of the first guide block 23 and the second guide groove 17.

Under the continuous rotation state of the first threaded rod 8, the multiple groups of second sleeves 13 gradually extend and increase, thereby lifting the cable. Example 3

[0020] like Figure 2-Figure 3 as well as Figure 10-15 As shown, the structure of the cable laying device disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that: The fixed plate 2 is provided with a snap-in groove 6, and the movable plate 3 is slidably arranged on the snap-in groove 6; Two groups of first racks 12 are installed on the clamping groove 6. The two groups of first racks 12 are symmetrically distributed, and each group of first racks 12 includes two. The two first racks 12 are respectively installed on the clamping groove 6 and the opposite faces of the moving plate 3. A first gear 43 is arranged between the two first racks 12. One end of the first gear 43 is rotatably connected to a second rack 44. A first guiding groove 9 is opened at the position of the clamping groove 6 corresponding to the second rack 44. The second rack 44 is limited to move in the clamping groove 6 through the first guiding groove 9. A second gear 45 is rotatably arranged at the position of the clamping groove 6 corresponding to the second rack 44. The output end of the motor 7 penetrates through the moving plate 3 and is connected to a third gear 46. The bottom of the first threaded rod 8 penetrates through the moving plate 3 and is connected to a fourth gear 47. The distance between the third gear 46 and the fourth gear 47 is matched with the distance between the third gear 46 and the second gear 45. A third guiding groove 30 is opened at the position of the moving plate 3 corresponding to the motor 7. The third guiding groove 30 is in a "C" - shaped structure and penetrates through the moving plate 3 and is opened on the clamping groove 6. A second support rod 32 is inserted into the interior of the third guiding groove 30. The end of the second support rod 32 penetrates through the moving plate 3 and is connected to a fifth gear 55. The fifth gear 55 can enable the third gear 46 to drive the second gear 45 or the fourth gear 47 to rotate synchronously. A collar 34 is slidably sleeved on the top end of the second support rod 32. A fourth elastic member 35 is arranged between the collar 34 and the top of the second support rod 32. Two fixing rods 33 are installed at one end of the collar 34 away from the fourth elastic member 35. Matching fixing holes 31 are opened at the positions of the moving plate 3 corresponding to the two fixing rods 33. Three groups of fixing holes 31 are opened at intervals at the position of the moving plate 3 corresponding to the third guiding groove 30. The telescopic assembly is installed on the moving plate 3. The moving plate 3 is slidably arranged on the fixed plate 2. When it is necessary to adjust the position of the telescopic assembly, the limit of the second support rod 32 is released, and then the second support rod 32 is moved so that the second support rod 32 moves along the third guiding groove 30. The second support rod 32 will drive the fifth gear 55 to move. When the fifth gear 55 moves between the second gear 45 and the third gear 46, the third gear 46 will drive the second gear 45 to rotate through the fifth gear 55. When the second gear 45 rotates, it drives the second rack 44 to move. During the movement of the second rack 44, it drives the first gear 43 to move. When the first gear 43 is displaced, it drives the first rack 12 to extend, thereby driving the moving plate 3 to move, so that the telescopic assembly arranged on the moving plate 3 drives the cable to move. When the fifth gear 55 moves between the third gear 46 and the fourth gear 47 , the third gear 46 can drive the first threaded rod 8 to rotate.

[0021] The specific solution is as follows: the mobile trolley 1 is moved to the specified position, and then the cable is clamped inside the fixed ring 5. After the movement is completed, the motor 7 is started. The motor 7 drives the fourth gear 47 to rotate through the cooperation of the third gear 46 and the fifth gear 55, and then drives the first threaded rod 8 to rotate. When the first threaded rod 8 rotates, due to the limiting cooperation of the first sleeve 4 and the first guide block 23 and the second guide groove 17 set between the first sleeve 4 and the second sleeve 13, the innermost second sleeve 13 will rise along the first threaded rod 8, and the corresponding first guide block 23 will slide along the second guide groove 17 opened on the inner side of the adjacent second sleeve 13. When the innermost second sleeve 13 rises to a certain height, it will squeeze the elastically set block 19, and then pass through the first guide block 23 and the second guide groove 1 7, driving the adjacent second sleeve 13 to rise along the first threaded rod 8. During the rising process, the elastically arranged second abutting block 27 is gradually no longer abutted. When the second abutting block 27 is ejected by the third elastic member 29, the first pull rope 21 gradually becomes relaxed, and the elastically arranged clamping block 19 gradually extends from the inside of the first receiving groove 18, thereby limiting the first guide block 23. After rising to a certain distance, the bottom of the lifted second sleeve 13 will be screwed to the outer surface of the first threaded rod 8, so that the lifted second sleeve 13 continues to rise along the first threaded rod 8, and the inner second sleeve 13 is connected to the lifted second sleeve 13, so that multiple groups of second sleeves 13 are extended. Under the continuous rotation state of the first threaded rod 8, multiple groups of second sleeves 13 gradually extend and increase, thereby lifting the cable. If it is necessary to fine-tune the position of the cable, release the limit of the second support rod 32, and then move the second support rod 32 to make the second support rod 32 move along the third guide groove 30, and the second support rod 32 will drive the fifth gear 55 to move. When the fifth gear 55 moves between the second gear 45 and the third gear 46, the third gear 46 will drive the second gear 45 to rotate through the fifth gear 55. When the second gear 45 rotates, it drives the second rack 44 to move, and the second rack 44 drives the first gear 43 to move during the movement. When the first gear 43 is displaced, it drives the first rack 12 to extend, thereby driving the movable plate 3 to move, so that the telescopic component set on the movable plate 3 drives the cable to move.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
