The fourth-largest oscillating deck 5 can provide certain protection for high altitude operation personnel, safe and reliable.
When staff needs the height and position to annular disk 7 to be adjusted, staff can to movable plate 33 to
Under pulled, movable plate 33 starts to compress the first spring 34 and second spring 35, then staff again to a left side three
Gusset 36 and right set square 37 are slided outward, and by the first inserted block 38 and the second inserted block 39 respectively from the first jack 601
It is pulled out in the second jack 602, what annular disk 7 can be convenient at this time slides adjustment on big guide rod 6, after adjustment, pine
Movable plate 33 is opened, under the first spring 34 and the effect of the elastic force of second spring 35, movable plate 33 is moved upwards, and drives a left side
Set square 36 and right set square 37 are moved inwardly, and the first inserted block 38 and the second inserted block 39 are turned back to respectively again to first
In jack 601 and the second jack 602, easily annular disk 7 can be fixed.
After movable plate 33 is pulled downward on the position of setting by staff, staff can be to the first L shaped plate 52
It is rotated up 180 degree with the second L shaped plate 54, and is hooked movable plate 33 by the first L shaped plate 52 and the second L shaped plate 54, is convenient for
Staff vacates hand and carries out other operations, easy to use.
