Further, the length of the cross rod is 15cm, and the vertical length of the cross rod is 80 cm.

Furthermore, the number of the reinforcing ribs is two, and the reinforcing ribs are respectively arranged on the left and the right.

Further, the length of the reinforcing ribs is 5 cm.

Further, the diameter of the fixing ring is 8cm, and the height of the fixing ring is 3 cm.

The utility model discloses following beneficial effect has:

the utility model discloses in, but the bolt lug connection pistol drill at horizontal pole top starts the pistol drill and can makes horizontal pole, the whole rotation of pole setting, and solid fixed ring is used for the stationary lead screw, and it can to keep stable, stir the bracket backing sheet when coexistence pole is rotatory with its adjustment to target height. The utility model discloses simple structure, available construction waste material preparation, it is with low costs, can improve the work efficiency that scaffold frame installation and demolishd, reduce the cost of labor. Meanwhile, the stacking space of the field materials is conveniently vacated, and the construction period is indirectly shortened.

Detailed Description

The scaffold bracket quick adjustment tool of the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, a scaffold bracket quick adjustment tool comprises an adjustment mechanism which is sleeved on a bracket screw rod and can rotate a supporting sheet on the bracket screw rod, and a driving mechanism which drives the adjustment mechanism to rotate.

The adjusting mechanism comprises a cross rod 2, a fixing ring 4 and two vertical rods 1, wherein two ends of the cross rod 2 are vertically welded and connected with the top ends of the two vertical rods 1 respectively, and the two vertical rods 1 are parallel. The fixing ring 4 is horizontally arranged in the middle position below the cross rod 2 and is connected with the cross rod 2 through a plurality of reinforcing ribs 3 in a welding mode, and the size of the fixing ring 4 is matched with the bracket screw rod. The middle position above the cross bar 2 is vertically welded with a bolt 5. The driving mechanism is a pistol drill which is matched with the bolt 5.

In this embodiment, the length of the cross rod 2 is 15cm, and the length of the vertical rod 1 is 80 cm. The number of the reinforcing ribs 3 is two, one is arranged at the left and the right, and the length of the reinforcing ribs 3 is 5 cm. The diameter of the fixing ring 4 is 8cm and the height is 3 cm. Wherein, pole setting 1, horizontal pole 2 and reinforcement bar 3 can adopt on-the-spot waste material reinforcing bar, steel pipe or other materials, and the material selection is loose.
