Mesh is 2 to 8.
In the present embodiment, when needing to dismantle the utility model, if under ice and snow weather, anchor ear inner ring surface and electric pole it
Between easily freeze and (have ice cube, ice sheet), the ice cube outside anchor ear, it is easy to regard to that can break into pieces, and the ice within anchor ear inner ring surface
Block, then more difficult removal, is so just unfavorable for dismounting of the present utility model.In the present embodiment, it is necessary to when dismantling the utility model,
If being freezed between anchor ear inner ring surface and electric pole, the first bolt of turn first, the first bolt can be made before the first bolt is unloaded
Moved towards defrosting cylinder body, after the first bolt band dynamic pressure disk presses spacing contact plate, drive piston rod, the movement of defrosting piston, solution
A part of hydraulic oil of frozen oil intracavitary enters internal oil channel through oil pipe, so as to which the bar that thaws is displaced outwardly, reels spring elongation, defrosting bar
Into the space between anchor ear and electric pole, ice cube therebetween is extruded, crushes ice cube, then can screwed out, unload
One bolt, now just easily anchor ear can be allowed to be separated with electric pole.And in the case where reeling spring effect, each knot at defrosting cylinder body
Structure can automatically reset.
