[0032] Working principle: Before using this wiring device for power transmission cable installation, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5As shown, by rotating the rotating frame 201, the screw rod 202 is driven to rotate in the internal thread of the installation frame 1, thereby driving the lifting plate 203 and the carrying plate 204 to move up synchronously. At this time, the lifting plate 203 drives the movement of the fixed tube 206.

Compared with the prior art that adopts multiple sets of bolts and nuts for fixing, it is more convenient and brings practicality to the staff when using it. The movement of the lifting plate 203 drives the movement of the pointer 210. The staff observes the pointer 210 and the scale 209, so that the height adjustment effect of the mounting plate 204 can be observed more intuitively, which brings convenience to the staff when using it. The movement of the mounting plate 204 drives the support rod 211 to slide inside the limiting groove 212, and then drives the pulling frame 214 to slide inside the support plate 213 by rotating the threaded rod 215, thereby driving the insertion block 216 to be engaged and fixed with the slot 217, so that the adjusted support rod 211 can be fixed and limited, thereby greatly improving the stability of the mounting plate 204, avoiding the phenomenon of self-rotation of the screw rod 202, and bringing convenience to the staff when using it;

[0033] By placing the cables in the mounting ring 311 respectively, and then sliding the moving block 303 in the sliding groove 302, the two connected cables are tightened, and then the moving rod 305 is pulled to drive the sliding sleeve 306 to move. At this time, the two ends of the sliding sleeve 306 are sleeved on the outside of the guide rod 307 to slide, thereby causing the second telescopic spring 308 to contract, and by loosening the moving rod 305 and then the resetting property of the second telescopic spring 308, the tooth plate 309 is engaged and fixed with the positioning groove 310, so that the two connected cables can be tightened and positioned, thereby reducing the looseness of the cables. The transmission line will be affected by factors such as wind load and temperature change during operation, so the displacement of the cable can be effectively avoided. Tightening the cable can make the contact points in close contact and increase the contact area, thereby reducing the contact resistance. The smaller the contact resistance, the smaller the energy loss. This is very important for improving the transmission efficiency and reducing the energy waste. It brings practicality to the staff when using it. By turning the knob rod 312, the rubber plate 313 is driven to squeeze and limit the cable, so as to achieve the effect of quickly fixing the cable. Through the design of the installation groove 314, it is convenient for the staff to operate the moving rod 305.
