[0035] Among them, the upper surfaces of both sides of the two moving seats 2 are provided with limit grooves 10, and the outer walls of both sides of the four sliding seats 18 are respectively slidably connected to the inner parts of the corresponding limit grooves 10, and the upper surface of the base 1 is provided with a first bidirectional threaded rod groove 6, and the inner part of the first bidirectional threaded rod groove 6 is rotatably connected to the first bidirectional threaded rod 11.

[0036] Furthermore, when using the device, it is started by connecting an external power supply. First, the base 1 is installed in the specified position through the mounting blocks installed on both sides.

In this way, pipeline ball valves of different lengths can be clamped and limited, which effectively improves the practicality and flexibility of the equipment, and makes it convenient for the staff to adjust the clamping device, thereby improving and reducing the workload of the staff.

[0038] Working principle: First, the base 1 is installed in the specified position through the mounting blocks installed on both sides, and then the output end of the second motor 12 is rotated to drive the first bidirectional threaded rod 11 to rotate while driving the movable seat 2 to move in the opposite direction to adjust the clamping length according to the length of the pipeline ball valve, and then the pipeline ball valve is placed on the opposite side of the clamping block 3, and then the output end of the first motor 8 is rotated to drive the second bidirectional threaded rod 14 to rotate while driving the sliding seat 18 to move in the opposite direction, and then the sliding seat 18 is moved in the opposite direction to drive the clamping block 3 to move in the opposite direction while clamping and limiting the pipeline ball valve, and then the pipeline ball valve is welded through external equipment, and then when the clamping block 3 needs to be removed, turn the fixing bolt 5 to rotate so that its other end is out of contact with the inside of the fixing bolt groove 17, and then pull the handle on the limit plate 4 to separate it from the fixed sleeve 7, and then pull the clamping block 3 to remove the limit seat 15 and the clamping block 3 from the sliding seat 18.
