The hoop is locked on the pole tower or other power equipment, and then the terminal cable is clamped to make the terminal cable in a straight state, which is convenient for later position locking of the terminal cable. Wiring operation is carried out at the terminal; as shown in Figure 8, the present embodiment provides the state when the present invention is locked on the tower, specifically, at first the clip is locked on the preset bolt hole of the mounting plate 11 by bolts, and then Lock the hoop at a suitable height on the pole tower so that the present invention is located below the position to be connected, then pass the terminal cable through the cable penetration part 2, and lock the position of the terminal cable through the cable locking part 3, and then carry out Wiring operations for terminal cables. It can be understood that the present invention can not only be locked on the tower, but also can be locked on different electric equipment by changing different types of hoops.

Since the distance between the terminal cable terminal and the pole tower is uncertain, and there is a certain angle between the terminal cable terminal and the pole tower, the present invention increases the wiring when the terminal cable is connected by adjusting the position and angle of the cable penetration part 2. effect, to prevent the terminal cable from being bent or even twisted during wiring, which will lead to unstable connection of the terminal cable.

When the terminal cable is conducted upwards, the connecting rod 321 drives the bonding plate 322 to rotate upwards. In order to guide the guide roller 324 in contact with the terminal cable to guide it, when the terminal cable is transmitted to the designated position, the connecting rod 321 rotates to the initial position under the action of its torsion spring, so that the anti-skid layer of the plane structure in the middle of the bonding plate 322 and the terminal cable Contact, when the upward guiding force of the terminal cable is removed, the terminal cable drives the connecting rod 321 to rotate downward through the fitting plate 322, so that the anti-skid layer of the arc-shaped groove 323 on the fitting plate 322 is in contact with the outer surface of the terminal cable, thereby increasing the adhesion. The contact area between the plywood 322 and the terminal cable further increases the anti-dropping effect of the terminal cable.

Referring to Fig. 5-Fig. 6, an adjustment part 4 is provided on the outside of the piercing ring 21, and the adjustment part 4 is used to synchronously adjust the position of the inner pole 31, so that the cable locking part 3 guides and protects terminal cables of different diameters; the adjustment Part 4 includes an adjustment ring 41 arranged on the outside of the piercing ring 21. The adjustment ring 41 is composed of two identical half rings spliced together, and the two half rings on the adjustment ring 41 are locked on the outside; each inner strut 31 is positioned at the One end of the outer side of the ring 21 is provided with an arc-shaped groove for the sliding insertion of the adjustment ring 41, and the inner surface of the adjustment ring 41 is provided with a top extension body 42 corresponding to the position of each inner support rod 31.
