[0048] In this embodiment, an opening is provided to embed the triangular connecting plate 5-1 to limit the front and rear positions of the supporting expansion plate 5-5, thereby ensuring that the two supporting expansion plates 5-5 and the fastening plate 7-1 are arranged vertically in a cross, thereby achieving uniform fastening support of the base 6 in four directions.

[0049] In this embodiment, a rubber plate is also provided at the bottom of the support expansion plate 5 - 5 to assist in enhancing the contact fastening stability.

[0050] In this embodiment, the handle 5-4 and the lower locking nut 5-3 are provided so that the lower locking nut 5-3 can be screwed down along the lower sleeve 4-2 by the handle 5-4, thereby pushing the lower outer sleeve 5-2 and the support expansion plate 5-5 at the bottom of the triangular connecting plate 5-1 to move downward until the support expansion plate 5-5 is in close contact with the ground, thereby achieving stable support;

[0051] When disassembly is required, the locking nut 5-3 is screwed in the reverse direction to move upward along the lower sleeve 4-2 a little, and then the lower outer sleeve 5-2 is operated to drive the support expansion plate 5-5 to move upward and off the ground.

[0052] In this embodiment, in actual use, the upper locking nut 3-1, the nut block 4-3 and the lower nut 7-4 can all be provided with handles for easy screwing or adjustment with reference to the handle 5-4.

[0053] In this embodiment, the upper locking nut 3-1 is provided so that after the upper expansion plate 3-4 is expanded outward along the hinge, the upper locking nut 3-1 is screwed and moved upward along the upper support screw 4-1, thereby pushing the upper outer sleeve 3-2 and the outer support reinforcement plate 3-3 to fit the bottom of the upper expansion plate 3-4, and the upper expansion plate 3-4 is in close contact with the bottom of the support beam 2, thereby achieving stable support;

[0054] When disassembly is required, the locking nut 3-1 is screwed in the reverse direction to move the upper support screw 4-1 downward, and the upper outer sleeve 3-2 drives the outer support reinforcement plate 3-3 to move downward and separate from the upper expansion plate 3-4, and then the upper expansion plate 3-4 is folded and contracted in the reverse direction along the hinge.

[0055] In this embodiment, the upper reinforcement rod 8 and the lower reinforcement rod 9 between two adjacent vertical support rods 4 are connected by a rotating fastener 11 to achieve oblique connection reinforcement, enhance the bearing capacity of the support and reinforcement structure, and further help improve the stability and safety of the entire structure.

[0056] In this embodiment, the upper reinforcing rod 8 and the lower reinforcing rod 9 are hinged to the support screw 4-1 and the lower sleeve 4-2 through a spherical hinge seat 10 to adapt to the adjustable connection between two adjacent vertical support rods 4 and facilitate storage after disassembly.

[0057] In this embodiment, during actual use, a rotating fastener can be added at the intersection of the two lower reinforcing rods 9 for connection, not shown in the figure, to increase the stability effect.

[0058] In this embodiment, during actual use, the lower outer sleeve 5-2 is provided with an installation hole for the lower part of the lower sleeve 4-2 to pass through, the upper outer sleeve 3-2 is provided with an installation hole for the upper support screw 4-1 to pass through, the base 6 is provided with an installation hole for the lower bolt 7-3 to pass through, and the lower sleeve 4-2 is provided with an installation hole for the upper support screw 4-1 to pass through.

[0059] When the utility model is specifically used, the adjusting nut block 4-3 rotates around the upper support screw 4-1, and the nut block 4-3 always fits against the top of the lower sleeve 4-2 when rotating. In this way, with the lower sleeve 4-2 and the upper support screw 4-1 coaxially arranged, it is ensured that the upper support screw 4-1 moves vertically to adjust the height of the top of the upper support screw 4-1. After adjustment in place, the bottom support beam 2 of the laminated plate 1 is embedded in the U-shaped seat 3-5; and the lower nut 7-4 is screwed tightly against the top of the base 6, and the lower bolt 7-3 is used to push the fastening plate 7-1 and the rubber plate 7-2 downward to closely contact the ground. The lower locking nut 5-3 is screwed along the lower sleeve 4-2 by turning the handle 5-4, thereby pushing the lower outer sleeve 5-2 and the support expansion plate 5-5 at the bottom of the triangular connecting plate 5-1 downward until the support expansion plate 5-5 is in close contact with the ground;

[0060] Then, the upper locking nut 3-1 is screwed upward along the upper support screw 4-1, thereby pushing the upper outer sleeve 3-2 and the outer support reinforcement plate 3-3 upward until the outer support reinforcement plate 3-3 fits against the upper expansion plate 3-4 for support reinforcement, so that the upper expansion plate 3-4 is in close contact with the bottom of the support beam 2;

[0061] Then, the upper reinforcing rod 8 and the lower reinforcing rod 9 between two adjacent vertical support rods 4 are connected through a rotating fastener 11 to achieve intermediate reinforcement, so that the support reinforcement structure is stable as a whole and can safely support the laminated plate 1.

[0062] To sum up, the utility model has a simple structure and a reasonable design. It can not only increase the bottom support area to improve the bottom support stability of the laminated plate, but also increase the top support area and the middle reinforcement structure to improve the overall stability and safety of the support reinforcement structure.

[0063] The above are only the preferred embodiments of the present utility model, and do not impose any limitations on the present utility model. Any simple modifications, changes, and equivalent structural changes made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
