By arranging the above structure, the utility model has the advantage of being easy to use when the tightening device is in use, and solves the problem that the traditional tightening device is inconvenient to use when in use, thereby being able to meet the customer's usage needs and effectively improving the tightening efficiency.

[0022] As a technical optimization solution of the present invention, the limiting assembly 9 includes a limiting plate 901, and the connection between the limiting plate 901 and the positioning column 4 is tightly fitted. A threaded pin groove 902 is provided on the right side of the positioning column 4. The upper and lower positions on the right side of the limiting plate 901 are threadedly connected to the limiting bolt 903, and the left end of the limiting bolt 903 extends to the inner cavity of the threaded pin groove 902 and is threadedly connected to the connection of the threaded pin groove 902.

[0023] In this embodiment, the position of the cable for winding up the tensioning wire can be limited by providing the limiting plate 901 , the threaded pin groove 902 and the limiting bolt 903 .

[0024] As a technical optimization solution of the present invention, the left end of the rotating shaft 2 passes through the driving box 1 and is provided with a nut 10, and the connection between the nut 10 and the rotating shaft 2 is welded.

[0025] In this embodiment, by providing the nut 10 , it is possible to facilitate an external electric wrench to drive the rotating shaft 2 to rotate.

[0031] In this embodiment, the device can be easily installed by providing the mounting plate 13 and the mounting hole 14 .

[0032] As a technical optimization solution of the present invention, a handle 15 is fixedly connected to the top of the screw rod 6, and an inspection plate 16 is fixedly installed on the front of the drive box 1 and located above the mounting plate 13 by screws.

[0033] In this embodiment, the provision of the handle 15 facilitates the rotation of the screw 6 , and the provision of the inspection plate 16 facilitates the staff to regularly replace and maintain the parts in the inner cavity of the drive box 1 .

[0034] Working principle: When the cable needs to be tightened, the staff fixes the device in the designated tightening position by using the mounting plate 13, the mounting hole 14 and the screws. Then, the staff moves the cable between the two positioning posts 4. Then, the staff moves the limit plate 901 so that the limit plate 901 fits tightly with the positioning post 4. Then, the staff rotates and moves the limit bolt 903 in sequence so that the limit bolt 903 and the threaded pin groove 902 cooperate to limit the connection between the limit plate 901 and the positioning post 4, thereby limiting the position of the cable.

[0035] Then, the staff moves the external electric wrench so that the external electric wrench drives the nut 10 to rotate. At the same time, the nut 10 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the gear 5 and the turntable 3 to rotate, so that the turntable 3 drives the positioning columns 4 on both sides to rotate, thereby causing the positioning columns 4 on both sides to rotate and tighten the cable. When the cable is tightened, the staff rotates the handle 15 so that the handle 15 drives the screw 6 to rotate and move downward on the inner surface of the drive box 1. At the same time, the screw 6 drives the movable plate 7 to move downward, so that the movable plate 7 drives the tooth plate 8 to move downward and engage with the gear 5, thereby limiting the rotating shaft 2 to prevent the cable from rotating loose. The device is simple to operate and easy to use, thereby being able to meet the customer's usage needs and effectively improving the tightening efficiency.
