The first clamp and the second clamp are connected by a clamp quick connector. The outer walls of the first clamp and the second clamp are provided with multiple symmetrical slots, and the movable adjustment block is clamped in the slots. The movable adjustment block includes a clamping block, a connecting block and a bolt top block. The connecting block is a right-angle connecting block. One end of the connecting block is fixedly set on the clamping block, and the other end of the connecting block is provided with a bolt top block.

[0008] The bolt top block includes a fixing nut and a screw. The fixing nut is fixedly arranged on the connecting block, and the screw and the fixing nut are threadedly connected.

[0009] A card connection entrance is provided on one side of the card slot, the shape of the inner groove of the card slot corresponds to the shape of the card block, a strip-shaped opening is provided on the card slot, and the opening is provided corresponding to the connecting block. When the movable adjustment block is inserted into the card slot, the card block is inserted into the card slot, and the connecting block is inserted into the opening above the card slot for fixation.

[0010] The first clamp and the second clamp are steel pipe clamps.

[0011] The materials of the clamping slot and the movable adjustment block are both steel.

[0012] The beneficial effects of the utility model are: simple structure, easy to use, the first clamp and the second clamp are fixed to the fixed pipe mouth through the clamp quick connector, the pipe mouth to be butted is aligned, and the movable adjustment block is inserted into the position to be adjusted for adjustment, and when welding to the position of the movable adjustment block, the movable adjustment block at the position to be welded can be removed for welding, without partial welding and then disassembling the adapter for welding, thereby improving the efficiency of pipe butt welding.
