[0005] The telescopic fixing clamp is fixedly connected to the screw jack via a steel column; a top screw is threadedly connected to one side of the telescopic fixing clamp, and another top screw is threadedly connected to another position perpendicular to the top screw.
[0006] Furthermore, the telescopic fixing clamp includes four fixing parts, each of which is a quarter-circular ring, and the interior of the fixing part is a hollow structure. An adjusting part is slidably connected inside the fixing part, and the fixing parts are connected to each other through the adjusting part.
[0007] Furthermore, limit holes are provided at both ends of the fixing member, and a plurality of adjustment holes are equidistantly provided on the adjusting member. When the size of the telescopic fixing clamp needs to be adjusted, the adjustment holes and limit holes at different positions are adjusted to a coaxial position and the position is fixed by the limit member.
[0008] Furthermore, the outer sides of the two fixing parts located at opposite positions are fixedly connected with steel columns, the steel columns are L-shaped, and the other ends of the steel columns are connected to the side of the diamond-shaped movable part.
[0009] Furthermore, the top screw is threadedly connected to a fixing member that is not connected to a steel column.
[0010] Compared with the prior art, the utility model has the following beneficial effects: the utility model fixes two pipes to be welded by two coaxial telescopic fixing hoops, thereby ensuring the coaxiality during welding and being adaptable to pipes of different diameters; the spacing between the two pipes to be welded is controlled by a screw jack; the utility model has a compact structure, can meet the welding operation needs in a narrow space, has a simple structure, and is easy to use.
