At this time, the moving plate and the V-shaped plate are both inside the U-shaped plate. Insert the other steel bar to be welded into the other U-shaped plate. Rotate the handwheel so that the driving sprocket drives the transmission chain and the driven sprocket to rotate, and then drive the two lead screws to rotate, so that the two lead screws drive the two moving plates to move. The V-shaped plate and the U-shaped plate clamp and position the steel bars, and the welding ends of the two steel bars are butted and welded". By using the clamping and fixing method, however, during welding, due to the blockage of the fixing plate, the welding part cannot be rotated and welded, and the abutting parts are not all welded, thus affecting the fixing effect of the abutting part after welding. Summary of the Utility Model

Two sleeves are rotatably connected to the two support plates through bearings. The two sleeves fix the steel bars through a fixing mechanism. Gear rings are fixedly connected to the two sleeves, and the two gear rings are driven by a driving mechanism.

[0006] Preferably, the driving mechanism includes a rotating shaft. The rotating shaft is rotatably connected to the support plate through a bearing. Second gears are fixedly connected to the two rotating shafts, and the two second gears are respectively meshed with the two gear rings.

[0007] Preferably, the number of teeth of the gear ring is greater than the number of teeth of the second gear.

[0008] Preferably, both ends of the rotating shaft are fixedly connected with first gears, racks are engaged on both of the first gears, telescopic rods are fixedly connected to both of the racks, and the two telescopic rods are fixedly connected to the bottom plate.

[0009] Preferably, the fixing mechanism includes a plurality of bolts, the plurality of bolts thread through the sleeve at equal circumferential distances, and abutting blocks are fixedly connected to the plurality of bolts.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] Embodiment 1: Refer to Figures 1-3, A steel bar positioner for building construction, comprising a bottom plate 15. Two support plates 3 are vertically and fixedly connected to the bottom plate 15. Two sleeves 2 are rotatably connected to the two support plates 3 through bearings. A steel bar 14 is fixed in each of the two sleeves 2 by a fixing mechanism. Two gear rings 1 are fixedly connected to the two sleeves 2 respectively. The two gear rings 1 are driven by a driving mechanism. By fixing the steel bar 14 in the sleeve 2, the driving mechanism drives the gear ring 1 to rotate, thereby driving the sleeve 2 to rotate, and driving the steel bar 14 to rotate. During welding, a circular welding is performed on the abutting portion of the steel bar 14, thus ensuring the fixing effect of the welding.

[0019] The driving mechanism includes a rotating shaft 11. The rotating shaft 11 is rotatably connected to the support plate 3 through a bearing. Two second gears 10 are fixedly connected to the two rotating shafts 11 respectively. The two second gears 10 are meshed with the two gear rings 1 respectively. The second gears 10 drive the gear rings 1 to rotate, thereby driving the sleeves 2 to rotate. Since the number of teeth of the gear ring 1 is greater than that of the second gear 10, a speed reduction rotation is performed, making the rotation speed slow, so as to match the rotation speed with the time required for welding.

[0020] Both ends of the rotating shaft 11 are fixedly connected with a first gear 9. A rack 7 is meshed with each of the two first gears 9. Two telescopic rods 8 are fixedly connected to the two racks 7 respectively. The two telescopic rods 8 are fixedly connected to the bottom plate 15. By the telescopic movement of the telescopic rods 8, the racks 7 are driven to move, so that the first gears 9 drive the rotating shafts 11 to rotate, and the rotating shafts 11 drive the second gears 10 to rotate.

[0021] The fixing mechanism includes a plurality of bolts 4. The plurality of bolts 4 penetrate through the sleeve 2 in a circumferential and equidistant manner by threading. A contact block 5 is fixedly connected to each of the plurality of bolts 4. The contact block 5 plays a role in limiting the bolts 4 to prevent the loss of the bolts 4. The number of bolts 4 is at least 3. By tightening the bolts 4, the steel bar 14 is abutted and fixed. By controlling the same moving distance of each bolt 4, the axes of the two steel bars 14 are on the same straight line, so as to ensure the regularity and beauty of the welding joint during welding.

[0022] During positioning, the steel bar 14 is placed into the sleeve 2, and then fixed by the fixing mechanism. As Figure 1 shown, during welding, the telescopic rods 8 contract to drive the racks 7 to move, so that the first gears 9 drive the rotating shafts 11 to rotate, the rotating shafts 11 drive the second gears 10 to rotate, and the second gears 10 drive the gear rings 1 to rotate, thereby driving the sleeves 2 to rotate and rotating the steel bar 14 in a circle to perform 360° welding on the abutting portion of the steel bar 14.

[0023] Example 2: Refer to Figures 1-3, as another preferred embodiment of the present utility model, on the basis of Embodiment 1, a ring 6 is fixedly connected to each of the plurality of bolts 4. A placement box 12 is placed on the bottom plate 15. A rotating tool 13 is placed in the placement box 12. The rotating tool 13 includes a regular hexagonal frame, and a handle is fixedly connected to the regular hexagonal frame. By sleeving the regular hexagonal frame on the nut of the bolt 14, the bolt 4 can be rotated. The ring 6 plays a role in limiting the placement of the regular hexagonal frame, which is beneficial to preventing the regular hexagonal frame from separating from the nut.

[0024] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
