[0041] In some embodiments of the present invention, referring to Figure 2 and Figure 3 The upper rod 10 is threadedly connected to the lower rod 20.

[0042] The upper rod 10 and the lower rod 20 are connected by bolts so as to be retractable in the extending direction, and the adjustment is convenient, the precision is high, the structure is simple, and the production is convenient.

[0043] In some embodiments, the upper rod 10 and the lower rod 20 can also be retracted in other ways. For example, the upper rod 10 and the lower rod 20 are sleeved, and mutually cooperating limit structures are set in the extension direction of the upper rod 10 or the lower rod 20 to perform limit adjustment at different heights.

[0044] In some embodiments of the present invention, referring to Figure 2 and Figure 3 One of the upper rod 10 and the lower rod 20 is provided with an internal thread 20a, and the other is provided with an external thread 10a matching the internal thread 20a, and the internal thread 20a is threadedly connected with the external thread 10a.

[0045] Specifically, the upper rod 10 is a hollow structure, and the inner wall is provided with an internal thread 20a, the lower rod 20 is provided with an external thread 10a, the lower rod 20 is sleeved inside the upper rod 10, and is threadedly connected to the upper rod 10; or, the lower rod 20 is a hollow structure, and the inner wall is provided with an internal thread 20a, the upper rod 10 is provided with an external thread 10a, the upper rod 10 is sleeved inside the lower rod 20, and is threadedly connected to the lower rod 20.

[0046] In some embodiments, the upper rod 10 and the lower rod 20 can also be threadedly connected via a connecting piece. For example, the upper rod 10 and the lower rod 20 are both provided with an internal thread 20a, the connecting piece is provided with an external thread 10a, and the upper rod 10 and the lower rod 20 are threadedly connected to the connecting piece respectively; or, the upper rod 10 and the lower rod 20 are both provided with an external thread 10a, the connecting piece is provided with an internal thread 20a, and the upper rod 10 and the lower rod 20 are threadedly connected to the connecting piece respectively.

[0047] In some embodiments of the present invention, referring to Figure 1 and 4 The bracket 100 also includes a rotating member 50, which includes a rotating body 51 and a rotating portion 52 connected to the rotating body 51. The upper rod 10 is penetrated and connected to the rotating body 51, and the rotating portion 52 forms a certain angle with the upper rod 10.

[0048] By providing the rotating member 50, it is convenient to rotate the upper rod 10 to adjust the height of the bracket 100. The rotating member 50 includes a rotating body 51, and the upper rod 10 is connected to the rotating body 51 through the rotating body 51, so as to connect the rotating member 50 with the upper rod 10. The upper rod 10 and the rotating body 51 can be fixedly connected or detachably connected. Preferably, the upper rod 10 and the rotating body 51 are welded. The rotating member 50 also includes a rotating portion 52 connected to the rotating body 51, and the rotating portion 52 forms a certain angle with the upper rod 10, so that it is convenient to rotate and more labor-saving when rotating.

[0049] It is understandable that the structure of the rotating body 51 can be plate-shaped, spherical, irregular, etc. In the present application, the rotating body 51 is plate-shaped and has a simple structure. The structural shape of the rotating portion 52 is not limited, and can be rod-shaped, column-shaped, irregular, etc. In the present application, the rotating portion 52 is rod-shaped. The angle between the rotating portion 52 and the rotating body 51 can be an acute angle, a right angle, an obtuse angle, etc. Preferably, the angle between the rotating portion 52 and the rotating body 51 is a right angle, so that, under the premise that the length of the rotating portion 52 is certain, the end of the rotating portion 52 away from the upper rod 10 is the farthest from the upper rod 10, and the rotation is more labor-saving.

[0050] In some embodiments of the present invention, referring to Figure 1 and 4 There are multiple rotating parts 52, and the multiple rotating parts 52 are arranged at intervals along the circumference of the upper rod 10.

[0051] By means of the plurality of rotating parts 52 arranged at intervals along the circumference of the upper rod 10, force can be applied to the upper rod 10 in different directions to rotate it, which is convenient for operation. Multiple persons can also apply force to rotate it at the same time, which is more labor-saving.

[0052] Specifically, the number of the rotating parts 52 may be two, three, five, etc. In the present application, there are two rotating parts 52. Preferably, the two rotating parts 52 are evenly distributed along the circumference of the upper rod 10.

[0053] In some embodiments of the present invention, referring to Figure 1 and 5 The bracket 100 further includes a stopper 60 , which is connected to the lower rod 20 . In a plane perpendicular to the lower rod 20 , the projection of the rotating member 50 and the projection of the stopper 60 at least partially overlap.

[0054] By setting a limit piece 60 connected to the lower rod 20, and in a plane perpendicular to the lower rod 20, the projection of the rotating piece 50 and the projection of the limit piece 60 at least partially overlap, thus, when the upper rod 10 and the lower rod 20 are height-adjusted or positioned, if the connection between the upper rod 10 and the lower rod 20 fails, the limit piece 60 blocks the rotating piece 50 to prevent the steel arch frame supported by the upper rod 10 from falling and hitting the workers, thereby causing an unsafe accident.

[0055] In some embodiments, the limiting member 60 may also be connected to the upper rod 10 , and in this case, the rotating member 50 is connected to the lower rod 20 .

[0056] It can be understood that, in a plane perpendicular to the lower rod 20 , the projection of the rotating member 50 and the projection of the limiting member 60 may partially overlap or completely overlap.

[0057] In some embodiments of the present invention, referring to Figure 1 and 5 The limiting member 60 is a limiting plate, and the lower rod 20 is vertically penetrated through the limiting plate.

[0058] By setting the limiting member 60 as a limiting plate, the structure is simple and easy to process. The limiting plate is vertically connected to the lower rod 20, so that multiple rotating members 50 are in contact with the limiting plate at the same time, which improves the limiting ability of the limiting plate and improves safety.

[0059] In some embodiments, the stopper 60 may be a plurality of sector plates spaced apart along the circumference of the lower rod 20, or may be a circular ring plate, etc. In the present application, the stopper plate is a rectangular plate, a through hole 61 is provided in the center of the stopper plate, the lower rod 20 is provided with the through hole 61, and is fixedly connected to the stopper plate.

[0060] In some embodiments of the present invention, referring to Figure 1 and 6The bottom support member 40 includes a bottom support plate 41 and two first limiting portions 42 arranged relatively on the bottom support plate 41 , and the first limiting portions 42 are connected to the bottom support plate 41 at a certain angle.

[0061] By providing the bottom support plate 41, the contact area between the support 100 and the construction platform is increased, the pressure is reduced, and the construction platform is not easily damaged. Generally, the construction platform is formed into a mesh structure by steel bars. By providing two first limit portions 42 at a certain angle to the bottom support plate 41, it is easy to clamp with the mesh construction platform, so that the support 100 is not easy to move, and the stability of the support is improved.

[0062] The angle between the first limit portion 42 and the bottom support plate 41 can be an acute angle, a right angle, an obtuse angle, etc. In the present application, the angle between the first limit portion 42 and the bottom support is a right angle. The distance between the two limit portions can be set according to the distance between adjacent steel bars of the mesh construction platform, and specifically set according to actual construction, so that the two limit portions can be stuck on both sides of two or three adjacent steel bars.

[0063] In some embodiments of the present invention, referring to Figure 1 and 7 The top support member 30 includes a top support plate 31 , and the top support plate 31 is vertically connected to the upper rod 10 .

[0064] By setting a top support plate 31 vertically connected to the upper rod 10 to support the steel arch frame, the support area is increased, the support pressure is reduced, the support points of the steel arch frame and the bracket 100 are not easily damaged, the structural strength of the steel arch frame is improved, and the service life of the bracket 100 is extended.

[0065] The top support member 30 is configured in a plate shape so that when the upper rod 10 is rotated, no obstruction is generated between the top support member 30 and the steel arch frame, thereby facilitating adjustment.

[0066] In some embodiments of the present invention, referring to Figure 7 and 8 The supporting member 30 also includes two second limiting portions 32 spaced apart from each other, the second limiting portions 32 having a first position and a second position. In the first position, the two second limiting portions 32 respectively form a certain angle with the supporting plate 31, and in the second position, the two second limiting portions 32 are both in the same plane with the supporting plate 31.

[0067] By providing the second limiting portion 32 with a first position and a second position, the second limiting portion 32 facilitates the rotation of the upper rod 10 when in the second position, and can be engaged with the steel arch frame when in the first position, thereby improving the support stability.

[0068] The second position-limiting portion 32 and the upper rod 10 can be rotatably connected by a torsion spring or the like to switch between the first position and the second position. In the first position, the angle between the second position-limiting portion 32 and the top support plate 31 can be an acute angle, a right angle, an obtuse angle, etc. In the present application, the angle between the second position-limiting portion 32 and the top support plate 31 is a right angle.

[0069] In some embodiments, the first limiting portion 42 may also have a third position and a fourth position. In the third position, the first limiting portion 42 forms a certain angle with the bottom support plate 41. In the fourth position, the first limiting portion 42 and the bottom support plate 41 are in the same plane.
