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

[0021] Please refer to Figures 1-3The utility model is a diagonal brace with adjustable length, comprising a shell 1, a hollow groove 10 is provided inside the shell 1, a blocking cover 2 is provided on the top of the hollow groove 10, a rotating shaft 5 penetrating the shell 1 is provided in the middle part of the hollow groove 10, one end of the rotating shaft 5 is rotatably connected to the shell 1, two movable seats 7 are symmetrically arranged inside the hollow groove 10, two screws 6 penetrating the movable seat 7 are symmetrically arranged on the rotating shaft 5, and the two screws 6 are reverse thread structures, a guide rod 9 penetrating the movable seat 7 is provided inside the hollow groove 10, and the movable seat 7 is slidably matched with the guide rod 9, two support rods 3 are symmetrically arranged at both ends of the shell 1, and a positioning seat 4 is hingedly provided at the outer end of the support rod 3, the support rod 3 can penetrate the shell 1, and two support plates 8 are hingedly provided at one end of the support rod 3 away from the positioning seat 4, and one end of the support plate 8 away from the support rod 3 is hinged to the movable seat 7, and a plurality of support plates 8 are located inside the hollow groove 10;

[0022] In this embodiment, one of the positioning seats 4 is fixed at a designated position on the vertical beam, and after the length of the structure is adjusted, the other positioning seat 4 is fixed at a designated position on the horizontal beam;

[0023] When the length of the structure needs to be adjusted, the rotating shaft 5 is rotated to rotate the two screws 6. Through the action of the reverse thread structure, the two moving seats 7 can slide synchronously and in opposite directions along the two screws 6. The guide rod 9 provided can improve the stability of the moving seats 7 when sliding.

[0024] When the two movable seats 7 are sliding, the angle between the two support plates 8 will change, so that the two support rods 3 can be extended and retracted at both ends of the shell 1, so that the overall length of the structure can be temporarily adjusted, and its supporting force can be temporarily adjusted, with low limitations during use.

[0025] In this embodiment, a limit seat 12 and a limit rod 11 passing through the limit seat 12 are provided at both ends of the blocking cover 2.
