[0028] In this embodiment, the lifting mechanism is provided in the clamp, the electric push rod 6 drives the lifting frame 3 to descend along the lifting groove 5, and the movable frame two 12 is driven to descend synchronously, and then the two ends of the pipe are clamped through the triangular grooves 17 in the middle of the movable frame one 11 and the movable frame two 12, so that the clamping action can be accurately controlled. Compared with the uneven clamping force of the traditional clamp, the clamp can make the pipe receive uniform clamping force during clamping, so as to ensure the stability of the pipe during processing. During pipe processing, stable clamping state helps to improve processing accuracy and reduce processing errors caused by pipe displacement or deformation.

[0031] Working principle: when the pipe is clamped, the pipe is inserted from one side of the base 1 and sequentially passes through the clamping mechanisms at both ends, until the middle of the pipe is supported by the two fixed frames 16, then the electric push rod 6 is started, the electric push rod 6 drives the lifting frame 3 to descend along the lifting groove 5, the lifting frame 3 drives the movable frame two 12 to descend synchronously after descending, and then the two ends of the pipe are clamped through the triangular grooves 17 in the middle of the movable frame one 11 and the movable frame two 12; when the length of the pipe changes, the motor 8 is started, the motor 8 drives the bidirectional screw rod 7 in the transmission shell 4 to rotate after being started, the bidirectional screw rod 7 drives the movable block 9 to move in the same direction or opposite directions after rotating, the movable block 9 drives the movable frame two 12 to move synchronously when the movable block 9 moves, the movable frame two 12 drives the movable frame one 11 below to move synchronously through the guide rod 15, so that the position of the clamping mechanism can be adaptively adjusted according to the pipe to be processed.
