On the described location fulcrum 10 through groove on slide plate 4, be positioned at the side in slide plate 4 plate face, cover has the support set 11 that one end leans against the respective side of slide plate 4, the other end leans against " U " shape after-poppet 9 respective inside wall; Location fulcrum 10 is positioned on slide plate 4, the another side relative with support set 11, cover has one end band to have can to insert the lock dog 16.1 of slide plate 4 upper rail 4.1 rotationally, the other end is provided with the locking wheel 16(of spring base 16.2 see Fig. 4, Fig. 5), lock dog 16.1 on locking wheel 16 adapts (see Fig. 6) with guide groove 4.1 width on slide plate 4, be enclosed within the spring 14 on the fulcrum 10 of location, its one end withstands on above described locking wheel 16 upper spring seat 16.2 (see Fig. 4), and other end support is on the relevant position of another madial wall of " U " shape after-poppet 9.
The lock dog 16.1 of described locking wheel 16 one end, the arcwall face of its side overlaps with the periphery 16.3 of this end on locking wheel 16, plane 16.4 and the described periphery 16.3 of opposite side form crescent stereo block, and thickness and described guide groove 4.1 width of its crescent moon adapt (see Fig. 4, Fig. 5, Fig. 6).When locating fulcrum 10 and entering in semi-circular recesses 4.2, rotate described locking wheel 16, its lock dog 16.1 is just inserted and in guide groove 4.1, the binding clip 1 adjusting the angle of pitch is locked motionless.
When needing the luffing angle adjusting described binding clip 1, with hand, locking wheel 16 is pushed to the side being provided with spring 14, make location fulcrum 10 in the guide groove 4.1 of slide plate 4 slippage to be applicable to position semi-circular recesses 4.2 in, then locking wheel 16 is unclamped, the thrust of spring 14 makes locking wheel 16 upper locking piece 16.1 be close to slide plate 4, use hand rotation lock fixed wheel 16 again, can spring in it after the lock dog 16.1 on it is aligned guide groove 4.1.
In order to strengthen the intensity of " U " shape after-poppet 9, on " U " shape two madial wall of " U " shape after-poppet 9, with the gap being positioned at described location fulcrum 10 and nut sleeve 6 upper mounting component, be parallel to location fulcrum 10 and be fixed with reinforcement 9.1(see Fig. 9, Figure 10).
When working to make clamping pliers, good integrity, stability are by force, on described caliper support 2, connect the connecting plate 2.2 of " U " shape frame 2.1, for being clipped in the upper and lower surface of binding clip 1, being arranged on two plates (see Fig. 8) at hinge 18 two ends.
Described clamping pliers is arranged on insulating bar 12, is to be welded and fixed on the termination leaving " U " shape opening of clamp clamp handle 13 perpendicular to " U " shape after-poppet 9, fixing in the sleeve pipe that clamp clamp handle 13 is plugged on insulating bar 12 top.
In order to adapt to the needs clamping electrification in high voltage drainage thread on differing heights electric pole, described insulating bar 12 is the short telescopic insulating bar 12 of pull of adjustable spreading.
When binding clip 1 direction of clamping pliers and the length direction of insulating bar 12 are in the state in the same way at 180 degree of angles, the drainage thread clamping horizontal direction is very convenient.
Fig. 3 is on the basis of Fig. 1, the angle between the binding clip 1 of clamping pliers and the length direction of insulating bar 12 is adjusted to the state diagram of an angle of 90 degrees, can obviously finds out from figure, and now to clamp decurved upright state drainage thread very convenient for clamping pliers.
The binding clip 1 of adjustment clamping pliers, can according to different angles curved under on-the-spot drainage thread, change the present position of described location fulcrum 10 on guide groove 4.1 one of in multiple semi-circular recesses 4.2, adjust the different angles of clamping pliers binding clip 1 pitching.
Above-described embodiment is only the indicative explaination carried out the utility model, is not unique technical scheme, every amendment, the part amendment carried out for purport with the technical solution of the utility model or equivalently to replace, and all belongs to protection range of the present utility model.
