DETAILED DESCRIPTION

[0020] As shown in the figure, this embodiment includes a support rod 1, and a horizontal cylindrical positioning seat 2 is provided at the upper end of the support rod 1. The axial center of the positioning seat 2 is fixedly connected to the support rod 1, and the protruding parts at both ends are cylindrical. The end faces of the protruding parts at both ends of the positioning seat 2 are provided with second grooves 9, and a rotating block 11 is installed in the second groove 9 through a bearing 10 to form a rotating mechanism, and the rotating block 11 is provided with a threaded hole outward; and a conversion mechanism that movably cooperates with it is provided on the positioning seat 2.

[0021] The conversion mechanism includes a rotating seat 3 that movably cooperates with the protruding part of the positioning seat 2. Threaded through holes corresponding to the threaded holes on the rotating block 11 are opened on the end faces of both ends of the rotating seat 3. The rotating seat 3 is fixedly connected to the rotating block 11 by a third bolt 12, so that the rotating seat 3 can rotate relative to the positioning seat 2; the positioning seat 2 can also omit the rotating mechanism, so that the rotating seat 3 and the positioning seat 2 are in direct contact and relative rotation is achieved through clearance fit, but the rotating seat 3 can make the rotation and transposition smoother and more stable by being connected to the rotating mechanism and cooperating with the positioning seat 2.

[0022] A first positioning groove and a second positioning groove are arranged outward at an angle of 90 degrees along the circumference of the rotating seat 3, and a first groove 8 corresponding to the position of the support rod 1 is provided on the circumference of the rotating seat 3, and the support rod 1 passes through the first groove 8, wherein the groove curvature of the first groove 8 is set according to the first positioning groove and the second positioning groove so that it can be in the supporting position, and the groove curvature of the first groove 8 is 90-95 degrees, and a certain error is allowed. The error range can also ensure the support position and facilitate processing.

[0023] The rotating seat 3 of this embodiment is composed of two parts, which are sequentially provided with a first component 31 and a second component 32 along the axial direction of the positioning seat 2. The first component 31 and the second component 32 are respectively composed of a connecting portion that cooperates with the positioning seat 2 and a first clamping plate 4 forming a first positioning groove on the outer side of the connecting portion and a second clamping plate 5 forming a second positioning groove. The butt joint end surface of the connecting portion of the first component 31 and the second component 32 is provided with an assembly groove that matches the diameter of the positioning seat 2 along the axis, and the protruding parts at both ends of the positioning seat 2 are sleeved for docking. After docking, the support rod 1 is located in the first groove 8, realizing the installation and cooperation between the rotating seat 3 and the positioning seat 2. The docking point of each first clamping plate 4 and each second clamping plate 5 on the first component 31 and the second component 32 is respectively provided with a positioning column 13 on one side and a positioning groove 14 on the other side corresponding to the positioning column 13, realizing the stable docking of each first clamping plate 4 and each second clamping plate 5.

[0024] At least a first fastening bolt 6 and a second fastening bolt 7 are provided at the four axial corners of the connection between the first and second components 31, 32. These bolts are connected to the ends of the components via nuts and tightened. The first and second fastening bolts 6 and 7 are arranged diagonally. Tightening these bolts prevents the first and second components 31, 32 from separating during use and better ensures the support force of the rotating base 3. These first and second fastening bolts 6 and 7 can also be replaced by screws, which pass through the first and second components 31, 32 and have their threaded ends connected to nuts.

[0025] The first fastening bolt 6 sequentially passes through the first component 31, the first groove 8, and the second component 32. The gap between the first fastening bolt 6 and the first groove 8 is adapted to the diameter of the support rod 1, and the first fastening bolt 6 is located at the center of the arc of the first groove 8. The first fastening bolt 6 cooperates with the edges of the first groove 8 to position the support rod 1 between them, thereby limiting the rotation of the rotating base 3 and forming a positioning mechanism. When the rotating base 3 adopts other positioning methods, its first fastening bolt 6 can also be arranged away from the first groove.

[0026] The edges at both ends of the first groove 8 are arc-shaped, and the arc shape is adapted to the radius of the support rod 1. When the arc edge is positioned with the support rod 1, the force points thereof are more evenly matched, which can achieve a stable positioning effect and improve the supporting force.

[0027] In this embodiment, the inner surface of the first clamping plate 4 is flat, used to support the square beam column. Each first clamping plate 1 is symmetrically screwed with a first bolt 41, the inner end of each first bolt 41 being connected to a first additional clamping plate 42 and engaging with it. The inner surface of the second clamping plate 5 is curved, used to support the curved beam column. Each second clamping plate 5 is also symmetrically screwed with a second bolt 51, the inner end of each second bolt 51 being connected to a second additional clamping plate 52 and engaging with it. This dynamic engagement prevents the first and second additional clamping plates 42 and 52 from maintaining their initial configuration when adjusting the first and second bolts 41 and 51, thereby better supporting the beam column.

[0028] The first additional plate 42 on the first plate 4 is a flat plate, and the second additional plate 52 on the second plate 5 is a curved plate coaxial with the inner surface of the second plate 5. These additional plates can provide a more stable support for the beam and column, and can also assist in clamping structures on both sides that need to be clamped and shaped. The first additional plate 42 and the second additional plate 52 can be set according to actual usage, and can be either one, both, or neither. The first plate 4 and the second plate 5 can also be set according to common usage, with the inner surfaces of both being flat or curved, allowing for different sizes to be suitable for beams and columns of different structural dimensions.

[0029] When the present embodiment needs to be repositioned, the first fastening bolt 6 is first removed, and the rotating seat 3 is rotated 90 degrees. At this time, the arc edge of the other end of the first groove 8 cooperates with the outer wall of the support rod 1. The first fastening bolt 6 is passed through the first component 31, the first groove 8 and the second component 32, and the nut is tightened with its end. Under the cooperation of the first groove 8 and the first fastening bolt 6, the rotating seat 3 is positioned to realize the repositioning of the supporting structure, which can meet the support of beams and columns with arc-shaped or square support surfaces. It is highly practical and easy to operate.
