The bottom ends of the first mounting frame 1 and the second mounting frame 2 correspond to the inner wall on the opposite side of the bottom end of the top plate 3, and are threadedly connected with the first threaded rod 12 and pass through the upper and lower sides. Rotate the first threaded rods 12 on both sides respectively, so that the pressure plate on the top of the first threaded rod 12 moves upward until it is close to the bottom of the operating table and forms a clamp with the top plate 3, restricting the first mounting frame 1 and the second mounting frame 2 to both sides of the operating table.

[0024] Specifically, a double-headed bolt 13 is detachably connected to the inner wall between the first mounting frame 1 and the second mounting frame 2, and the shapes of the left and right sides of the bottom ends of the double-headed bolt 13 are matched with the shapes of the inner walls of the limiting holes 17. The bottom of the double-headed bolt 13 is inserted into the limiting holes 17 on both sides to strengthen the connection relationship between the first mounting frame 1 and the second mounting frame 2. Through the detachable connection relationship between the first mounting frame 1 and the second mounting frame 2, the device is easy to disassemble and assemble, and can reduce the space required for the device when it is shelved, so as to facilitate the storage and management of the device.
