[0020] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the utility model.

[0021] Such as Figure 1-2As shown in the figure, the fixture for fixing steel pipes in this embodiment includes support frames 1 and support legs that are symmetrically arranged left and right. A connecting rod 2 is arranged between the support frames 1. The support frames 1 are of U-shaped structure, and the inner cavity of the support frames 1 is used for supporting the steel pipes. Through grooves 3 are symmetrically formed on the support frames 1. A fixing frame 4 is rotatably installed in the through grooves 3 through torsion springs. The fixing frame 4 includes a horizontally arranged limiting part 401 and a pressing part 402 perpendicular to the limiting part 401. When the steel pipe is placed, the steel pipe presses the limiting part 401, and the fixing frame 4 rotates. When the lower part of the steel pipe abuts against the bottom of the inner cavity of the support frame 1, the limiting part 401 is rotated to the outside of the fixing frame 4, and the pressing part 402 presses on the upper part of the steel pipe. A socket 5 is fixedly arranged at the outer wall position of the support frame 1, and a plug rod 6 that is used in cooperation with the limiting part 401 is inserted into the socket 5. When the plug rod 6 is inserted into the socket, the plug rod 6 is simultaneously located at the gap between the limiting part 401 and the support frame 1 to limit the support frame 1.

[0022] Furthermore, a first rubber pad 7 is arranged at the inner wall position of the support frame 1, and a spring is also arranged between the first rubber pad 7 and the inner wall of the support frame 1. The pressing part 402 can be pressed downwards, and the spring deforms, so that the gap between the limiting part 401 and the support frame 1 increases, which is convenient for inserting the plug rod 6 and at the same time ensures the stability of fixing the upper part of the steel pipe.

[0023] Furthermore, the side of the pressing part 402 close to the inner cavity of the support frame 1 is of arc-shaped structure.

[0024] Furthermore, a second rubber pad 8 is arranged at the inner wall position of the pressing part 402.

[0025] Working principle: When the steel pipe is placed, the steel pipe will first press the limiting part 401, and the limiting part 401 drives the fixing frame 4 to rotate. When the lower part of the steel pipe abuts against the bottom of the inner cavity of the support frame 1, the limiting part 401 is rotated to the outside of the fixing frame 4, and the pressing part 402 presses on the upper part of the steel pipe. Press down the pressing part 402 to make the spring between the pressing part 402 and the first rubber pad 7 deform, so that the gap between the limiting part 401 and the support frame 1 increases, and then insert the plug rod 6 to fix the steel pipe.

[0026] When the steel pipe needs to be removed, pull out the plug rod 6, then lift the steel pipe upwards, and the fixing frame 4 rotates under the action of the torsion spring, and the steel pipe can be removed upwards.
