[0002] An operating table is an essential tool for doctors during surgery, serving as a crucial piece of equipment for patient placement and providing a more convenient surgical environment. Based on their intended use, operating tables are categorized into multi-functional operating tables, gynecological operating tables, and orthopedic operating tables, among others. According to the movement mechanism of the operating table surface, they can be broadly classified into three types: electrically driven, hydraulically driven, and manually driven.

[0003] As a core support device in clinical surgery, the electric operating table's structural design must adapt to the positioning needs of different surgical procedures. It typically includes core structures such as a base, lifting assembly, headboard, backboard, lumbar support, hip support, and push plate. Among these, the leg support, as a crucial component related to lower limb support, is primarily used to support the patient's legs. However, currently, the leg support area is usually locked to the hip support area via connectors. Disassembly requires specialized tools, which not only affects work efficiency for medical staff but is also extremely inconvenient. Therefore, improving the ease of leg support connection is a pressing technical problem that needs to be solved in this case. Utility Model Content

The pressure plate 400 has a through hole in the middle, and a locking handle 600 is provided on the through hole. The locking handle 600 is threadedly connected to the bottom of the first adjusting arm 200. Rotating the locking handle 600 moves the pressure plate 400 towards the first adjusting arm 200, thereby causing a pair of first upper teeth to engage with the corresponding first and second upper teeth, thus locking the first adjusting arm 200. The leg plate 500 is fixedly mounted on the second adjusting arm 300.

[0021] The connecting post 110 is fixedly disposed at the tail of the locking seat 100, and has a transverse hole communicating with the vertical hole inside; the transverse hole and the vertical hole form a mounting cavity; the outer circular surface of the connecting post has a positioning hole communicating with the transverse hole. The rotating arm 120 is hinged in the middle of the vertical hole, with one end extending into the horizontal hole and the other end extending downward in the vertical hole. The locking post 130 is movably mounted on the rotating arm 120, and its top extends out of the positioning hole via a spring 131. When the rotating arm 120, located in the transverse hole, is pressed down, the spring 131 is compressed, so that the top surface of the locking post 130 is located in the positioning hole.
