[0039] As Figure 8 And Figure 9The right side of the third supporting plate 15 is fixedly connected with a blocking strip 30 for blocking the first moving plate 16. When the second bed plate 3 needs to be reset after traction is completed, the threaded plate 12 is controlled to move to the right side. The movement of the threaded plate 12 can drive the strip-shaped plate 31 and the first limiting rod 14 to move correspondingly.

A circular roller (7) is fixedly connected to the outer surface of the rotating shaft (6). A second bed plate (3) is fixedly connected to the outer surface of the circular roller (7). A first bed plate (2) is fixedly connected to the upper surface of the base plate (1). A threaded plate (12) and a third support plate (15) are slidably connected to the upper surface of the base plate (1), and the third support plate (15) is fixedly connected to the first support plate. (4) On the right side, the third support plate (15) and the threaded plate (12) are connected by a self-locking mechanism. The self-locking mechanism is connected to the second bed plate (3) by a connecting mechanism. A strip plate (31) is fixedly connected to the left side of the threaded plate (12). A gear (33) is fixedly connected to the outer surface of the rotating shaft (6). A tooth (32) that matches the gear (33) is integrally formed on the strip plate (31). A driving mechanism for driving the threaded plate (12) to move horizontally is provided above the bottom plate (1). The driving mechanism includes a motor (9) and a threaded rod (11). The self-locking mechanism includes a first movable plate (16) slidably connected to the upper surface of the third support plate (15). The first movable plate (16) has two symmetrical connecting plates (45) slidably connected inside. The two sides of the connecting plates (45) are respectively fixedly connected to a second movable plate (17) and a first wedge plate (18). The two first wedge plates (18) are fixedly connected to a second spring (39) on the side away from each other. The two second springs (39) are fixedly connected to a fourth support plate (21) on the end away from each other. The two fourth support plates (21) are fixedly connected to the left side of the first movable plate (16). Two first fixing plates (13) are fixedly connected to the left side of the threaded plate (12). The two first fixing plates (13) are fixedly connected to the side away from each other with a first limiting rod (14). The interior of the two second moving plates (17) is provided with a strip groove (19) and a socket (20) that are adapted to the first limiting rod (14). The socket (20) is located at the right end of the strip groove (19) and is connected to the strip groove (19). The upper surface of the third support plate (15) is fixedly connected to a fifth support plate (22). The side of the fifth support plate (22) close to the first moving plate (16) is fixedly connected to a second wedge block (23) that is adapted to the first wedge plate (18), and the second wedge block (23) corresponds one-to-one with the first wedge plate (18). The upper surface of the base plate (1) is fixedly connected to a baffle (34) for blocking the first support plate (4) from moving to the left. The output end of the motor (9) is fixedly connected to a threaded rod (11). The end of the threaded rod (11) away from the motor (9) slides through the first support plate (4), the fifth support plate (22) and the first moving plate (16) in sequence and is rotatably connected inside the second support plate (10). The threaded plate (12) is threadedly connected to the outer surface of the threaded rod (11). The motor drives the threaded plate to move to the right, causing the second bed board to move away from the first bed board, thus providing horizontal traction to the patient's lumbar spine. After traction is completed, the motor drives the threaded plate to move to the left until the first support plate moves into contact with the baffle. At this point, the second bed board moves to the left back to its initial state. The motor continues to drive the threaded plate to move to the left. Since the first support plate, the third support plate, and the second wedge block are in a relatively fixed state, as the threaded plate drives the second moving plate, the first moving plate, the first wedge plate, the rectangular block, and the third moving plate to move horizontally to the left, the second wedge block will squeeze the first wedge plate outwards. The movement of the shaped plate can drive the second moving plate, the rectangular block, and the second limiting rod to move accordingly and compress the second spring. When the second moving plate moves to a point where it is no longer in contact with the first limiting rod, the second limiting rod completely moves out of the limiting hole. At this time, the threaded plate continues to move to the left, which will drive the strip plate to move accordingly, and the first limiting rod will slide along the strip groove accordingly. The continued movement of the strip plate can drive the teeth to move to mesh with the gear. Then, the movement can drive the gear to rotate upward. The upward rotation of the gear can drive the rotating shaft, the third moving plate, and the second bed board to rotate upward. The upward rotation of the second bed board can provide vertical traction for the patient's lumbar spine.
