[0031] The existing distribution network engineering conductors need to use two tensioners alternately to achieve the effect of fast conductor, but the alternating use of two tensioners is troublesome and has high operation requirements;

[0032] according to Figure 1 As shown, by adding a third hook 22 on the basis of the original second hook 11, it is no longer necessary to use two wire tensioners alternately, so that the second hook 11 and the third hook 22 can simultaneously pull the wire to move, thereby quickly conducting the wire without requiring high operation requirements;

[0033] Specifically, according to Figure 1As shown, by rotating the first shaft 3 and the second shaft 15, the first shaft 3 drives the first winch 4 to rotate, the first winch 4 pulls the first steel cable 5 to shrink and wrap around the outer surface of the first winch 4, the first steel frame 8 and the second hook 11 are moved by the first steel cable 5, and the third steel cable 17 is driven to rotate by the second shaft 15, the third steel cable 17 is pulled to shrink and wrap around the outer surface of the second winch 16, and the second steel frame 20 and the third hook 22 are moved by the third steel cable 17, so that the second hook 11 and the third hook 22 can pull the wire to move at the same time.

[0034] A first bevel gear 12 is installed at one end of the first steel cable 5, a second bevel gear 13 is installed at one end of the second capstan 16, and a third bevel gear 14 is installed inside the connecting frame 1, and the third bevel gear 14 is meshed with the first bevel gear 12 and the second bevel gear 13. Since the third bevel gear 14 is meshed with the first bevel gear 12 and the second bevel gear 13, when the second shaft 15 rotates clockwise, the second bevel gear 13 at one end of the second shaft 15 will mesh and drive the third bevel gear 14 to rotate, and the third bevel gear 14 will mesh and drive the first bevel gear 12 to rotate counterclockwise, so that the second capstan 16 can recycle the fourth steel cable 18 while the first steel cable 5 releases the second steel cable 7, so that the device can be used and operated in a multifunctional manner.

[0035] The upper end of the first steel frame 8 is slidably connected with the first sliding column 10, and the upper end of the first sliding column 10 is connected to the lower end of the second hook 11. The outer surface of the first sliding column 10 is provided with a first spiral groove 24, and the inner wall of the first steel frame 8 is also installed with a first protrusion 26, one end of the first protrusion 26 is slidably connected to the inside of the first spiral groove 24, and the inner wall of the first steel frame 8 is also installed with a first spring 25; the upper end of the second steel frame 20 is slidably connected with the second sliding column 21, the upper end of the second sliding column 21 is connected to the lower end of the third hook 22, and the outer surface of the second sliding column 21 is provided with a second spiral groove 27, and the inner wall of the second steel frame 20 is also installed with a second protrusion 29, one end of the second protrusion 29 is slidably connected to the inside of the second spiral groove 27, and the inner wall of the second steel frame 20 is also installed with a second spring 28.

[0036] The working principle of the second hook 11 is the same as that of the third hook 22. Figure 2 As shown, when the second hook 11 hooks the wire, the first steel cable 5 pulls the first steel frame 8 and the second hook 11 to slide toward the connecting frame 1. Due to the large resistance at the wire, when the second hook 11 pulls the wire, the wire will pull the second hook 11 to slide away from the connecting frame 1, so that the second hook 11 will be pulled to the first slide column 10 to slide, and is slidably connected to the first spiral groove 24 through the first protrusion 26, so that the first slide column 10 drives the second hook 11 to rotate, and the second hook 11 drives one end of the wire to rotate, so that the wire is wrapped around the outer surface of the second hook 11, and one end of the wire is twisted, so as to increase the strength of one end of the wire and reduce the occurrence of the wire being torn and broken.

[0037] according to Figure 2 and Figure 3 As shown, the other end of the second shaft 15 passes through the connecting frame 1, one end of the connecting frame 1 is rotatably connected to the rotating rod 23, the upper end of the rotating rod 23 is rotatably connected to the ratchet 35, and the second shaft 15 passes through the ratchet 35; the interior of the second shaft 15 is slidably connected to the square column 31, one end of the second sliding column 21 passes through the second bevel gear 13, one end of the first bevel gear 12 is provided with a square groove 30, and one end of the square column 31 is used to insert into the interior of the square groove 30; a handle 32 is installed at the other end of the square column 31, and a plug 34 is installed at one end of the handle 32, and a circular hole 33 is also provided at one end of the second shaft 15, and the plug 34 is used to insert into the interior of the circular hole 33, and the plug 34 and the circular hole 33 are clearance-matched.

[0038] according to Figure 2 and Figure 3 As shown, when the first capstan 4 and the second capstan 16 need to rotate simultaneously and in the same direction, the handle 32 is pushed to slide toward one end, and the handle 32 drives the square column 31 to slide toward one end, and the square column 31 is inserted into the interior of the square groove 30. When the second shaft 15 rotates, the second shaft 15 will drive the square column 31 to rotate, and the square column 31 drives the first bevel gear 12 and the second capstan 16 to rotate, so that the first capstan 4 and the second capstan 16 can rotate simultaneously and in the same direction.

[0039] It should be noted that when the handle 32 slides to one end, the plug 34 at one end of the handle 32 will be inserted into the inside of the circular hole 33. Due to the clearance fit between the plug 34 and the circular hole 33, the plug 34 is snap-fastened inside the circular hole 33.

[0040] It should be noted that when the rotating rod 23 rotates, the rotating rod 23 drives the ratchet 35 to rotate, and the ratchet 35 drives the second shaft 15 to rotate. The working principle of the rotating rod 23 and the ratchet 35 is the existing technology and will not be described in detail.

[0041] The third bevel gear 14 is slidably connected to the inside of the connecting frame 1, and the third bevel gear 14 is operably engaged with the first bevel gear 12 and the second bevel gear 13; a square shaft column 40 is installed on one side of the third bevel gear 14, the square shaft column 40 passes through the connecting frame 1, and a trapezoidal block 39 is installed on one side of the square shaft column 40; a square frame 36 is installed on one side of the connecting frame 1, and a threaded rod 37 is threadedly connected to the upper end of the square frame 36, and a conical column 38 is installed on the lower end of the threaded rod 37, and the conical column 38 is used to abut against the trapezoidal block 39; a third spring 41 is installed on the outer surface of the square shaft column 40, and the other side of the third spring 41 is connected to the connecting frame 1; one side of the square shaft column 40 is rotatably connected to one side of the third bevel gear 14.

[0042] By rotating the threaded rod 37, the threaded rod 37 drives the cone column 38 to slide downward, and the cone column 38 slides downward to abut against the trapezoidal block 39, so that the cone column 38 squeezes the trapezoidal block 39 to slide to one side, and the trapezoidal block 39 drives the square shaft column 40 to slide to one side. Figure 5 As shown, the third bevel gear 14 is driven to slide to one side by the square shaft column 40, so that the third bevel gear 14 is engaged with the second bevel gear 13 and the first bevel gear 12. In this way, when the second bevel gear 13 rotates, the second bevel gear 13 drives the third bevel gear 14 to rotate, and the third bevel gear 14 drives the first bevel gear 12 to rotate.

[0043] It should be particularly noted that one side of the square shaft column 40 is rotatably connected to the inside of the third bevel gear 14 , so when the third bevel gear 14 rotates, the square shaft column 40 will not affect the third bevel gear 14 .

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
