As shown in fig. 1, in some embodiments, the bed 101 includes a main body 1011 and a leg plate (not shown), the main body 1011 is provided with a plug port 1012, the leg plate is detachably mounted on the plug port 1012, and the adapter mechanism 10 is detachably connected to the plug port 1012. It should be noted that, the traction frame 200 is not limited to the bed body 101 mounted to the operating table 100 in the above manner, for example, in other embodiments, the bed body 101 includes a main body 1011 and side rails 1013 mounted on two sides of the main body 1011, and the switching mechanism 10 is detachably mounted on the side rails 1013.

As shown in fig. 2 and 3, in some embodiments, traction mechanism 20 includes a first support assembly 21, a cross beam 22, and a second support assembly 23, cross beam 22 connecting first support assembly 21 and second support assembly 23, first support assembly 21 for supporting a patient's lower leg, and second support assembly 23 for supporting a patient's foot. Wherein,

the adapter mechanism 10 and the cross beam 22 are rotatably connected with the first support assembly 21. In this embodiment, by providing the switching mechanism 10 and the cross beam 22 in rotational connection with the first support assembly 21, the traction of the leg of the patient can be facilitated by rotating the first support assembly 21 and/or by rotating the cross beam 22 to change the posture of the traction frame 200, for example, by rotating the cross beam 22 to raise the second support assembly 23 above or lower the second support assembly 23. In addition, if the adaptor mechanism 10 and the cross member 22 are extended in opposite directions, by rotating the adaptor mechanism 10 relative to the first support assembly 21 from the original extending direction to the opposite extending direction toward the original extending direction and rotating the cross member 22 relative to the first support assembly 21 from the original extending direction to the opposite extending direction toward the original extending direction, the traction frame 200 can be switched between two states, namely, the traction frame 200 originally applied to the left leg traction and the traction frame applied to the right leg traction, and after changing the extending directions of the adaptor mechanism 10 and the cross member 22, the traction frame 200 can be applied to the right leg traction, and the design manner enables the traction frame 200 to have versatility, so that the cost of the traction frame 200 can be reduced and the occupied space of the traction frame 200 can be reduced.

If the adapter mechanism 10 and the cross beam 22 are mounted on the first support assembly 21 in such a way that they extend in directions of two angles, the posture of the traction frame 200 can be changed by adjusting the angle between the cross beam 22 and the adapter mechanism 10, so as to facilitate the traction of the leg of the patient, for example, when the leg of the patient needs to be lifted by 30 degrees for fixing and supporting, before the traction frame 200 is mounted on the bed body 101 of the operating table 100, the cross beam 22 can be mounted on the first support assembly 21 in such a way that it is 150 degrees with respect to the adapter mechanism 10, and then the adapter mechanism 10 is mounted on the bed body 101 of the operating table 100, so that the traction frame 200 is suitable for supporting the leg by 30 degrees.
