Connect, the insulating bar lower end of lowermost end connects a handwheel, by rotating handwheel, adjustable, insulating bar height.
Further, be also to have cord on insulating bar, by draw and attenuate rope erect insulating bar come.
Further, hook main body includes hook part and straight sidewall, and stopper slot is arranged on straight sidewall.
Further, tongue upper surface is pressed to be provided with an arc-shaped notch.
Further, clamping device is hard aluminium alloy manufacture using 7075.
The beneficial effects of the utility model are:By setting the screw rod through connecting plate, screw rod upper end can by connecting shaft
That slides is connected in the bar-shaped trough of pressure tongue, presses one end of tongue to be nested in the stopper slot of hook main body wall, can be in hook main body
Moved in stopper slot, be threaded on the outside of screw rod, be arranged with button turn nut, coordinated by the screw thread of screw rod and button turn nut, it is real
The lifting of existing screw rod, so as to change the angle of pressure tongue and horizontal plane, pressure tongue and the contact being grounded are ensure that, can be pressed from both sides securely
Firmly it is grounded.Earth brace is connected insulating bar by quick union, and is to have cord on insulating bar, is restricted by drawing and attenuating, you can
Drop bar is erected to come.Convenient, anti-dropout that the utility model drop bar is hung and clamping wire it is solid and reliable.Job safety, height
Imitate, be directly perceived controllable, and saving manpower, having ensured the personal safety of operating personnel and the convenience of operation conscientiously.

Embodiment
Content of the present utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment:
As Figure 1-Figure 4, a kind of drop bar, including clamping device 10, and the earth brace 20 being connected with clamping device.
Clamping device 10 includes hook main body 11, runs through the screw rod of connecting plate with the integrally formed connecting plate 12 of hook main body, one
14, and it is connected to the pressure tongue 13 of screw rod upper end.
Hook main body 11 includes hook part 111 and straight sidewall 112, and the radian of hook part 111 is adapted to connecing for plurality of specifications
Ground wire, a stopper slot 113 is provided with straight sidewall, one end of pressure tongue 13 is nested in stopper slot 113, can be moved in stopper slot 113
It is dynamic.
Bar-shaped trough 131 is offered on pressure tongue 13, the upper end of screw rod 14 is slidably connected to bar-shaped trough by a connecting shaft 132
In 131, the upper surface of pressure tongue 13 is provided with arc-shaped notch 133.
