Further, also comprise the abutment sleeve of Universal drive rotary head described in, this abutment sleeve is set in outside described Universal drive rotary head, and its two ends are detachable being connected with described insulating bar and spiral bayonet socket wire clamp respectively.
Further, also comprise and establish female ring-like button, the other end of described insulating bar is provided with external screw thread, and ring-like button is connected to the other end of described insulating bar by its internal thread rotation; Described insulation pull rope is fixed on this ring-like button.
Further, also comprise insulation addition rod and connecting ring, insulation addition rod two ends are respectively equipped with the external screw thread identical with the other end external screw thread of described insulating bar, and connecting ring is provided with the internal thread that can be screwed in the described insulating bar other end and insulation addition rod one end.
Further, the two ends of described abutment sleeve adopt screw to be connected with described insulating bar and spiral bayonet socket wire clamp respectively.
Compared to prior art, the utility model has following beneficial effect:
1, the utility model is by being set with for anti-jamming tensioning spring outward in its Universal drive rotary head, make the advantage that its Omnipotent ground device not only with prior art has, spiral bayonet socket wire clamp can also be avoided and insulating bar is in 90 ° or close to 90 ° time, occur that insulating bar cannot be rotated in place, spiral bayonet socket wire clamp cannot the problem of clamping wire;
2, the utility model arranges abutment sleeve further, and make this abutment sleeve be set in outside described Universal drive rotary head, and its two ends are detachable being connected with described insulating bar and spiral bayonet socket wire clamp respectively, make, when job task does not need Universal drive rotary head, Universal drive rotary head to be fixed by abutment sleeve, prevent spiral bayonet socket wire clamp from arbitrarily swinging, cannot mount, and when the rotary head of needs Universal drive, directly pull down abutment sleeve, very convenient.
Below in conjunction with drawings and Examples, the utility model is described in further detail; But a kind of improvement type Universal grounding device of the present utility model is not limited to embodiment.
Accompanying drawing explanation
Fig. 1 is decomposing schematic representation of the present utility model;
Fig. 2 is the partial structurtes schematic diagram after Universal drive rotary head of the present utility model puts abutment sleeve.
Embodiment
Embodiment, refer to shown in Fig. 1, Fig. 2, a kind of improvement type Universal grounding device of the present utility model, comprise spiral bayonet socket wire clamp 1, insulating bar 3, insulation pull rope 4 and Universal drive rotary head 2, one end of Universal drive rotary head 2 connects spiral bayonet socket wire clamp 1, the other end connects one end of insulating bar 3, the other end of insulating bar 3 connects insulation pull rope 4, the tail end of this insulation pull rope 4 is connected with snap close 5, and this device can be fixed on object with insulation pull rope 4 by this snap close 5 easily.The utility model also comprises for anti-jamming tensioning spring 21, and this tensioning spring 21 is sleeved on outside described Universal drive rotary head 2, and its two ends are resisted against insulating bar 3 and spiral bayonet socket wire clamp 1 respectively.This tensioning spring 21 can avoid two of Universal drive rotary head 2, namely spiral bayonet socket wire clamp 1 and insulating bar 3 is in 90 ° or close to 90 ° time, insulating bar 3 cannot be rotated in place, the problem of the not clamping wire of spiral bayonet socket wire clamp 1.
Preferred as one, the utility model also comprises the abutment sleeve 22 of Universal drive rotary head 2 described in, this abutment sleeve 22 is set in outside described Universal drive rotary head 2, and its two ends are connected in detachable with described insulating bar 3 and spiral bayonet socket wire clamp 1 respectively.Specifically, the two ends of described abutment sleeve 22 adopt screw 23 to be connected with described insulating bar 3 and spiral bayonet socket wire clamp 1 respectively.When job task does not need Universal drive rotary head 2, Universal drive rotary head 2 can be fixed by this abutment sleeve 22, such as: when completing vertical direction mounting ground connection, abutment sleeve 22 will be pushed into tensioning spring 21 place and fix, can prevent the spiral bayonet socket wire clamp 1 of ground connection from arbitrarily swinging, the problem that cannot mount.When the rotary head 2 of needs Universal drive, then only abutment sleeve 22 need be pushed away tensioning spring 21.
