When the utility model works, the table legs are first fixed on the base with the positioning block, and then the round pipe to be welded is snapped into the inner side of the limit jaw, and the height of the positioning seat is adjusted so that the positioning rod is correspondingly inserted into the positioning hole of the round pipe to be welded Inside, the driving mechanism drives the pull rod to move, and the handle of the pull rod fixes the round tube to be welded on the limit claw. By adjusting the height of the lifting seat, the lower end of the round tube to be welded is attached to the table leg, and the round tube is fixed on the On the table legs, follow-up welding operations can be carried out. Compared with the prior art, the utility model has the beneficial effects that the round pipe can be fixed on the table leg, preventing the relative movement between the round pipe and the table leg, facilitating the welding of the round pipe and the table leg, and improving the welding efficiency and Welding precision, saving time and effort. More convenient. This tooling can fix the pipe fittings on the cuboid workpiece for welding and other operations.

As a further improvement of the utility model, the driving mechanism includes a cylinder fixed on the lifting seat, the piston rod extension end of the cylinder is fixedly connected with an adapter plate, and the adapter plate is fixedly connected with the other end of the pull rod. The cylinder drives the pull rod to move through the adapter plate, and the handle of the pull rod pushes the round tube to the inside of the limiting jaw, so that the round tube is fixed on the limiting jaw.

As a further improvement of the utility model, two tie rods are arranged on the tie rod guide seat, and the two tie rods are respectively located on the left side and the right side of the round pipe to be welded. The two pull rods cooperate with each other, one left and one right, and pull the round tube to be welded to the inside of the limiting jaw to ensure that the round tube is firmly fixed on the limiting jaw.

In order to fix it more conveniently after adjusting the height of the lifting seat, a positioning screw 1 is provided on the lifting seat.

In order to facilitate fixing the positioning rod, the positioning seat is provided with two positioning screws.

As a preference of the present utility model, the handle and the pull rod are hinged.
