[0030] Based on the above structure, the angle positioning assembly 4 includes a short threaded rod 41, a vertical shaft 42 and an L-shaped rod 43. The bottom end of the short threaded rod 41 is connected to the bearing of the first guard rod 1. A vertical shaft 42 is provided on the left side of the short threaded rod 41. The bottom end of the vertical shaft 42 is welded and fixed to the first guard rod 1. The outer side of the short threaded rod 41 is threadedly sleeved with an L-shaped rod 43. The left end of the L-shaped rod 43 is slidably sleeved on the outer side of the vertical shaft 42. The right end of the L-shaped rod 43 is clamped and connected with the second guard rod 2 through a rectangular groove 3.

[0038] The working principle of the utility model is as follows:

[0039] When in use, first adjust the device according to the shape of the wall to be supported. If it is necessary to support two walls at the corner, the first guard bar 1 and the second guard bar 2 connected by the bearing are rotated and adjusted to be perpendicular to each other. Figure 6 As shown in , the short threaded rod 41 is then manually rotated to control the L-shaped rod 43 to move downward along the vertical axis 42, so that the right end of the L-shaped rod 43 is inserted into the rectangular groove 3, so that the first guard bar 1 and the second guard bar 2 can be positioned to ensure the stability of the device state;

[0040] Then, according to the actual height of the wall to be supported, the crank 13 can be manually rotated to drive the second conical teeth 14 to rotate. At this time, the first conical teeth 12 meshing with the second conical teeth 14 can be used to drive the long threaded rod 11 to rotate, so that the movable plate 6 can be controlled to stably lift and lower along the limit plate 10, and the two movable plates 6 can respectively drive the top first guard bar 1 and the second guard bar 2 to rise and fall synchronously, and under the action of multiple connecting rods 5, multiple first guard bars 1 and second guard bars 2 distributed in the vertical direction can be controlled to be equidistantly expanded or contracted, so as to reasonably adjust the overall height of the device according to the height of the wall to be reinforced, so as to achieve full and effective support for different walls, and at the same time as the movable plate 6 is lifted and lowered, it can also drive the inner support rod 91 and the outer support rod 92 to telescopically slide. After the movable plate 6 is lifted and lowered to a suitable position, the positioning bolts 93 can be tightened to position the inner support rod 91 and the outer support rod 92. By setting the support assembly 9, the support strength and stability of the device for the wall can be improved;

[0041] In summary, the device is not only height-adjustable so as to be suitable for wall reinforcement of different heights, but also capable of adjusting the device state so that the device Figure 1 and Figure 6 The two states shown in the figure can be switched as needed, which is convenient for stable support of a single wall or a double-sided wall at a corner.
