Meanwhile, by changing the telescopic length of the two first clamping pieces and the movement position of the second clamping piece, the principle of three points determining a circle is used to clamp tubular aluminum profiles of different sizes.

[0027] The embodiment can achieve the following effects through the above arrangement: the tubular aluminum profile is placed between the two clamping assemblies, one end of the tubular aluminum profile is supported by the two first clamping pieces and the second clamping piece on one side, and the other end of the tubular aluminum profile is supported by the two first clamping pieces and the second clamping piece on the other side, so that the clamping effect on the tubular aluminum profile is more stable. Meanwhile, by changing the telescopic length of the two first clamping pieces and the movement position of the second clamping piece, the principle of three points determining a circle is used to clamp tubular aluminum profiles of different sizes.

[0028] One side surface of the support block 12 is rotationally connected below the mounting frame 15, the two first clamping pieces 10 are fixedly connected with the support block 12, and the two first clamping pieces 10 are symmetric about the rotation axis of the support block 12; the bottom of the support block 12 is fixedly arranged on the top of the conveying belt 1;

[0029] The embodiment can achieve the following effects through the above arrangement: the tubular aluminum profile is placed between the two clamping assemblies, one end of the tubular aluminum profile is supported by the two first clamping pieces and the second clamping piece on one side, and the other end of the tubular aluminum profile is supported by the two first clamping pieces and the second clamping piece on the other side, so that the clamping effect on the tubular aluminum profile is more stable.
