Fixed board, the top of the support column side are provided with the second helical gear to be cooperated with the first helical gear by 3rd bearing,
And second side of the helical gear away from support column rotating disk is installed, installed at marginal position of the rotating disk away from support column side
There is rotational handle.
Preferably, the bottom even of the bottom plate is provided with anti-skid screw.
Preferably, vibration damper plate is installed between the damper and supporting plate.
Preferably, the bottom of the support column is provided with four ribs, and the one end of ribs away from support column is fixed
At the top of supporting plate.
Preferably, it is provided with antiskid thread before the rotational handle.
Compared with prior art, the beneficial effects of the utility model are：Stable type crane stand bar structure installation is limited
Position pipe, can be fixed on specified location by leg by the stop screw inside position-limiting tube, coordinate the anti-skid screw of bottom base plate
So that the stabilization of leg is more preferable, crane is effectively avoided operationally to produce displacement, the operation to crane with ground
Certain inconvenience is caused, and device is provided with damper and coordinates vibration damper plate to play preferable cushioning effect, can be to lifting
Machine plays preferable protective effect, while coordinates the ribs between supporting plate and support column, can make the stability of structure more
Height, and the inside of the support column of the stable type crane stand bar structure is provided with studdle, can pass through two groups of mutual cooperations
The first helical gear and the second helical gear drive studdle move upwards, and the second helical gear by driven by rotary disc its rotation,
So that it is more laborsaving to operate, consequently facilitating crane is lifted.
