Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Example:

As shown in Figure 1, a line lifter for a straight section of a distribution network includes a fixing device 1 and a support arm 4, one end of the support arm 4 can rotate around the fixing device 1, and the other end of the support arm 4 A thread-lifting arm 7 with adjustable direction is arranged on it, and a thread-lifting device 8 for adjusting the height of the thread-lifting hook 10 is arranged on the thread-lifting arm 7 .

The supporting arm 4 can rotate around the fixing device, and it can be connected and fixed with the fixing device through the turntable 3, so that the supporting arm can rotate 360 degrees, which is convenient for adjusting the direction of the supporting arm.

The fixing device 1 can be realized by using a U-shaped clamp and bolts 2 for fixing the U-shaped clamp. The fixing device can also be realized by using a hoop. Using hoops to fix the entire wire lifter can only be fixed on the rod body of the utility pole. Compared with the fixing method of the U-shaped clamp, it is not only inconvenient to install and set the wire lifting arm and other structures, but also makes the lifting The connection stability of the wire arm is limited, and it is fixed on the main body of the utility pole, so there is a requirement for the firmness of the fixation. If the installation is unstable, the entire wire lifter will easily slide down, affecting the stability of the entire wire lifter. The fixing method of the U-shaped card seat can be directly fixed on the cross arm. Even if it is easy to install, there is no need to worry about the sliding of the fixed position of the thread lifter.
