In order to facilitate the operation of the device, a mounting frame 14 is arranged at the left side of the U-shaped plate 1, an insulating rod 15 is arranged below the mounting frame 14, and the insulating rod 15 is detachably mounted on the insulating support.

In order to facilitate the fixation of the first tension springs 3 and the balance of the inclined plate 2 during rotation, at least two first tension springs 3 are symmetrically fixed on each inclined plate 2, first bulges are arranged at the outer ends of the inclined plates 2, second bulges corresponding to the first bulges are arranged on the side walls of the U-shaped frames, one ends of the first tension springs 3 are fixed on the first bulges, and the other ends of the first tension springs are fixed on the second bulges.

In order to facilitate the stability of the ropes 12 when being jacked up by the electric wires, the number of the ropes 12 is at least two, the ropes are symmetrically arranged front and back, the number of the wedge blocks 11 slidably mounted on each inclined plate 2 is consistent with that of the ropes 12, and the wedge blocks 11 are slidably mounted on the inclined plates 2 in a sliding groove sliding block connection mode.

In order to facilitate the cutters 8 to effectively cut off the sundries, the blades of the cutters 8 are serrated, and the blades of the two serrated cutters 8 can be meshed with each other.

For driving convenience, the elastic strength of the third tension spring 13 is greater than that of the first tension spring 3, and the elastic strength of the first tension spring 3 is greater than that of the second tension spring 9.

The specific working process of the invention is as follows: the initial state of this device is that first extension spring 3 is in the contraction state, and first extension spring 3 makes the lower extreme of swash plate 2 outwards extend this moment, and second extension spring 9 is in the contraction state, and cutter 8 retracts to the knife rest 7 in this state, and third extension spring 13 is in the contraction state, and the lower extreme opening part of U-shaped plate 1 is arranged in to rope 12 intermediate position under this state, and wedge 11 is in the below wedge 11 of swash plate 2 and not contacts with cutter 8 bottom.

On the basis of the above state, the insulating rod 15 is arranged on the mounting frame 14, the device is driven to be buckled at the position of the electric wire with sundries from the upper end of the electric wire, the insulating rod 15 is driven to move downwards, the electric wire moves towards the inside of the U-shaped plate 1, the electric wire drives the middle position of the rope 12 to move towards the inside of the U-shaped plate 1, the rope 12 is tightened, the third tension spring 13 has a stretching tendency in the process of tightening the rope 12, but the elastic strength of the third tension spring 13 is greater than that of the first tension spring 3, so that the lower ends of the two inclined plates 2 are driven to contract inwards in the process of tightening the first rope 12, the first tension spring 3 is stretched in the process and enables the first tension spring 3 to have a rebound tendency and elastic potential energy, the connecting plates 5 with the barbed nails 6 on the two inclined plates 2 gradually approach and contact in the process that the lower ends of the two inclined plates 2 approach towards the middle, and the free ends of the sundries on the, when the two connecting plates 5 are contacted with each other, the barbed nails 6 on the two connecting plates are mutually meshed and fork-mount and fix the free ends of the sundries, the device moves downwards along with continuous movement, the rope 12 is continuously tightened, at the moment, the connecting plates 5 are mutually contacted and limited, the tightening of the rope 12 cannot realize the continuous inward rotation of the lower end of the inclined plate 2, at the moment, the tightening of the rope 12 causes the third tension spring 13 to be stretched, the free ends of the sundries are fixed by the barbed nails 6, the upper end moves upwards to realize the stretching and tightening of the sundries, meanwhile, the continuous upward movement of the middle position of the rope 12 realizes the continuous stretching of the third tension spring 13, the wedge block 11 gradually approaches the bottom of the cutter 8 in the process and realizes the outward movement of the cutter 8 along the cutter rest 7 under the extrusion effect of the inclined plane of the wedge block 11, and the second tension spring 9 is stretched and has rebound tendency and elastic potential, the cutter 8 moves outwards to enable the saw-toothed blade parts to correspond and be meshed with each other, the sundries which are already supported tightly are easily cut off, if the sundries cannot be cut off once, the device can be repeatedly pulled up and down, and the sundries can be repeatedly cut by the cutter 8 under the action of the resetting action of the second tension spring 9 and the third tension spring 13 in the reciprocating up-and-down pulling process, so that the sundries can be smoothly cut off.

After the above actions are completed, the device is lifted upwards, the electric wire is gradually separated and is not extruded on the rope 12, in the process, the third tension spring 13 is reset, the middle position of the rope 12 is arranged at the opening of the U-shaped plate 1, the reset of the third tension spring 13 realizes the reset of the wedge-shaped block 11 and does not extrude the bottom of the cutter 8 any more, under the reset action of the second tension spring 9, the cutter 8 retracts into the cutter frame 7, and along with the continuous reset of the rope 12, the lower ends of the two inclined plates 2 are gradually opened and restored to the initial state under the reset action of the first tension spring 3, the cutters 8 at the two sides are completely separated in the process, the connecting plates 5 are mutually separated, and a leaving channel is provided for the electric wire, so that the electric wire can pass through the device, the device is lifted to be completely separated from the electric wire, sundries on the electric wire are cut off, and the remaining length of the sundries can not be connected with the adjacent electric wire, so that potential safety hazards can not be caused and cleaning can not be carried out any more.

All parts that contact with the cable conductor in this device are all preventing to cause the electric shock accident at workman's operation in-process with insulating material.

Compared with the traditional equipment, the device has the following advantages:

1. in the pressing-down process of the device, the rope 12 is tightened to be used as a power source, so that the rope 12 is tightened to drive the lower ends of the two sloping plates 2 to be extruded towards the middle, the extrusion process firstly realizes that the two connecting plates 5 are close to each other and extruded, the free end of sundries is fixed, the rope 12 is continuously tightened after the extrusion process is completed, but swash plate 2 can not rotate because the spacing of connecting plate 5, and debris are tensile this moment, and along with the rope 12 last move up drive wedge 11 extrusion cutter 8 bottom make cutter 8 outwards move along knife rest 7, two zigzag cutter 8 interlock each other cut off the debris that have extended, and third extension spring 13 extension spring provides a buffering stage for the electric wire shifts up after swash plate 2 is spacing, and this stage realizes stretching of debris and drive the stretching out of cutter 8 and cut off debris, and debris are propped open tighter, make things convenient for the cutting of debris more.

2. The problem that this device will be solved is, gets rid of length and surpasss the long debris of interval between two electric wires, can leave a segment debris and continue to stay on the electric wire after getting rid of the completion, but this segment debris can not cause the potential safety hazard, consequently need not expend energy once more and get rid of it, and natural morals and manners can decompose by oneself, therefore this device contrast conventional equipment more has practical meaning, and the operation effect is convenient.

3. This device compares traditional hook and pulls clearing apparatus, and this device makes things convenient for the application of force simultaneously more conveniently to catch debris, fixes debris free end earlier and props debris tight cutting again, improves cutting efficiency and rate of accuracy, and contrast flame projecting unmanned aerial vehicle equipment, this device optional condition all can use, can not cause conflagration potential safety hazard, and is safer.
