The rotating mechanism 5 is used to provide a rotating force; one end of the rotating tube is fixedly connected to the output end of the rotating mechanism 5, the rotating tube is a hollow structure, and the other end of the rotating tube is used to vertically sleeve on the screw 2 of the adjustable support 1; and one end of the rotating mechanism 7 is fixed to the other end of the rotating tube 6, and the other end of the rotating mechanism 7 is used to screw the adjusting nut 4 to a preset position on the screw 2;

[0025] Specifically, the rotating tube 6 may be, for example, a steel tube, and the rotating mechanism 7 may be, for example, a C12 steel bar, but the present invention is not limited thereto, and any structure that can achieve the functions achieved in the above-mentioned embodiment may be used.

[0026] In one or more embodiments, the rotating mechanism 5 includes: a rotating unit 8 and a sleeve 9. The rotating unit 8 is used to provide a rotating force; and the sleeve 9 is fixed to the output shaft of the rotating unit 8, and the sleeve 9 is fixedly connected to the one end of the rotating tube 6; wherein, when the rotating unit 8 is started, it can drive the sleeve 9 to rotate, thereby driving the rotating tube 6, the rotating mechanism 7 and the adjusting nut 4 to rotate.

[0027] In one or more embodiments, first holes are respectively formed on both sides of the output shaft of the rotating unit 8 , and second holes are respectively formed on both sides of the sleeve 9 .

[0028] In one or more embodiments, the two first holes and the two second holes are adapted to correspond to each other.

[0029] In one or more embodiments, the rotating mechanism 5 further includes two latches 10 , and the two latches 10 are respectively inserted into the second hole and the first hole, so as to fix the sleeve 9 on the output shaft of the rotating unit 8 .

[0030] In one or more embodiments, the number of the at least one rotating mechanism 7 is two, and one end of the two rotating mechanisms 7 is respectively welded and fixed to the other end of the rotating tube 6 .

[0031] In one or more embodiments, the sleeve 9 is located at the top center of the one end of the rotating tube 6 and is fully welded and fixedly connected to the side wall of the one end of the rotating tube 6 .

[0032] In one or more embodiments, a first washer is disposed between the sleeve 9 and the output shaft of the rotating unit 8 , and a second washer is disposed between the latch pin 10 and the second hole.

[0033] Specifically, the rotating unit 8 can be, for example, an electric wrench, but the present invention is not limited thereto, and any structure that can achieve the functions achieved in the above-mentioned embodiments can be used; wherein, the sleeve 9 is placed at the top center position of the rotating tube 6 and is fully welded to the side wall of the rotating tube 6; a first washer is placed on the sleeve 9, and there are second holes on both sides of the sleeve 9. The first holes on both sides of the tungsten steel shaft (the output shaft of the rotating unit 8) are aligned and clamped with force, and then the pin (latch pin 10) is inserted into the hole, and then the pin is fixed with the second washer, and the sleeve 9 cannot be pulled out, which means it is installed.

[0034] In one or more embodiments, the length of the rotating tube 6 is equal to the length of the screw 2 minus the distance from the support plate 3 to the preset position;

[0035] Specifically, the length of the rotating tube 6 needs to be determined based on the length of the screw 2 and the height of the preset position. For example, the length of the screw 2 is 2000 mm, and the height of the preset position is 200 mm (the exposed length of the screw 2 is 200 mm, that is, the distance from the support plate 3 to the adjusting nut 4 is 200 mm). Then the length of the rotating tube 6 at this time is 2000 mm minus 200 mm, which equals 1800 mm. If part of the structure of the sleeve 9 is located in the rotating tube 6, the height of the part of the structure of the sleeve 9 located in the rotating tube 6 needs to be added to 1800 mm.

[0036] In one or more embodiments, the rotating mechanism 7 is made of steel, and the length of the rotating mechanism 7 is 150 mm;

[0037] Specifically, the two rotating mechanisms 7 are respectively welded to the two sides of the bottom of the rotating tube 6, using C12 steel bars, and the welding length is 5d (double-sided welding).

[0038] In actual application, the erection height is determined according to the support frame design plan, and the exposed length of the screw 2 of the adjustable support 1 is determined. The adjustable support with the same exposed screw 2 is placed in different areas, and the corresponding length quick adjustment device is used for adjustment. Figure 1 The adjustable support 1 is flipped 180°) on the ground or fixed on the device, and the switch of the electric wrench (rotating unit 8) is turned on. Its rotation drives the steel pipe (rotating pipe 6) to rotate, thereby driving the steel bar (rotating mechanism 7) welded at the bottom end of the steel pipe to rotate, and the steel bar can rotate the adjusting nut 4 to the designed position; specifically, since the length of the steel pipe corresponds to the length of the screw rod 2 (the length of the screw rod 2 minus the height of the preset position), when the adjusting nut 4 is screwed to the preset position, the bottom of the sleeve 9 will abut against the bottom of the screw rod 2 (the end away from the support plate 3), so that the exposed length of the screw rod 2 of the adjustable support 1 can be accurately and quickly adjusted; wherein, the two rotating mechanisms 7 are respectively located on both sides of the two ends of the adjusting nut 4, and can be in a cross shape. When the electric wrench is started, the two rotating mechanisms 7 can respectively abut against the two ends of the adjusting nut 4, thereby driving the adjusting nut 4 to be screwed in or out on the screw rod 2.

[0039] In summary, the quick adjustment device of the utility model has the following beneficial effects:

[0040] 1. The structure is simple and reasonable, and the production is simple. It uses common materials on the construction site and can make use of waste materials, thus achieving the purpose of saving resources and reducing costs;

[0041] 2. It can greatly improve construction efficiency, save labor, and achieve the effect of reducing costs and increasing efficiency;

[0042] 3. The exposed length of the screw rod 2 of the adjustable support 1 can be adjusted quickly and accurately.
