[0007] The adjusting mechanism comprises a screw rod, an end of the connecting member away from the reference plate is fixedly connected with a threaded barrel, the screw rod is threadedly connected to the threaded barrel, and a pressing plate is installed at the end of the screw rod close to the reference plate;

[0008] The limiting groove of the reference plate and the limiting groove of the pressure plate are arranged correspondingly.

[0009] As a further improvement of the utility model, the reference plate and the pressure plate are made of angle steel, and a handle rotating rod is installed at one end of the screw rod away from the pressure plate.

[0010] As a further improvement of the utility model, a rotating base is arranged in the middle of the back of the pressing plate, and one end of the screw rod is rotatably connected in the rotating base.

[0011] As a further improvement of the utility model, the handle rotating rod is movably arranged on the screw rod.

[0012] As a further improvement of the utility model, a reinforcing rod is fixedly installed between the two connecting members.

[0013] As a further improvement of the utility model, a measuring rod is installed in the middle of the back of the reference plate, the measuring rod is a telescopic rod, and a size scale is arranged on the measuring rod.

[0014] The beneficial effects of the utility model are:

[0015] The device has a simple structure and is easy to manufacture. It can quickly align pipes in a narrow space. The reference plate is placed against the butt ends of the two pipes, and the screw is rotated to adjust the two pressure plates to press on the upper and lower pipes, so that the butt ends of the upper and lower pipes are pressed on the reference plate to form a precise alignment. In addition, the measuring rod on the back of the reference plate can quickly measure the vertical distance between the pipe and the wall, thereby reducing the labor intensity of workers and improving the efficiency of pipe butt welding.
