[0002] As a commonly used equipment, steel wooden tables use solid steel as the base and a wooden table top. They are often used in life. They can be used to place items or as display stands to display items. They are also a popular leisure table in schools.

[0003] After searching, the existing Chinese patent with publication number CN202022304106.4 discloses an environmentally friendly and durable steel and wooden table. By pulling out the expansion plates on both sides of the main table, the telescopic block in the middle of the expansion connecting shaft is lengthened, the expansion connecting shaft moves the expansion slot, the expansion plate expands outward, and the pin at the bottom of the expansion plate is disengaged from the pin slot. The expansion plate is rotated to be parallel to the main table, and then the expansion plate is pushed inward, the expansion connecting shaft is shortened, and then the support leg is moved to the bottom of the expansion plate. The support leg moves in coordination with the main table moving slot and the expansion plate moving slot through the moving block on the top. The card block on the top of the moving block is limited by the reset spring and the card slot at the top of the moving slot. The area of ​​the entire table is increased, and more items can be placed.

[0004] The above technical solution has the following defects: although such a steel and wooden table structure is provided with an extension plate that can be rotated and opened, the bottom support legs need to be adjusted during actual use. In order to facilitate the expansion of the steel and wooden table to increase the usable area, a steel and wooden table with a retractable tabletop is proposed. The tabletop is provided with an electrically opened and closed auxiliary sub-tabletop, so that the user can unfold the tabletop more conveniently, and a lifting component is provided so that the expanded tabletop can be kept in the same plane as the main tabletop for use, so that the tabletop area can be effectively increased.

[0005] In view of this, the author improves and solves the above problems, concentrates on research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.
