A sliding groove 407 is provided on the upper surface of the rotating frame 406, and one side surface of the rotating frame 406 is a hollow through structure. The number of main round teeth 403 and secondary round teeth 404 are four, and they are distributed in mirror symmetry in pairs. Springs 411 are fixedly installed on the inner arc surfaces of the main round teeth 403 and the secondary round teeth 404. The number of springs 411 is two, and they are movably sleeved on both sides of the connecting rod 401.

[0023] In the present embodiment: the placement groove 2 on one side of the outer frame 1 can be used to place various surgical tools inside, and the connected rotating device 4 inside the extended boss 3 on one side, when it is necessary to lift or lower the patient's limbs, according to the lifting of the rotating frame 406, the main round teeth 403 and the secondary round teeth 404 are engaged and misaligned while the rotating frame 406 is flipped. Since the secondary round teeth 404 remain stationary on the connecting rod 401, the rotating main round teeth 403 will engage with the secondary round teeth 404, and the fastening nuts 402 fixed at both ends of the connecting rod 401 are tightened by rotating the fastening nuts 402 to keep the connecting rod 401 stable, and the purpose of the spring 411 is to reset the main round teeth 403 of the spring 411 after loosening the fastening nuts 402, so that the rotating frame 406 returns to a horizontal state.

[0024] Secondly, by rotating the rotating frame 406 at an angle, the angle can be changed up and down in the initial horizontal state, so that surgery can be demonstrated on a patient's local limbs, and the change in angle can allow medical students to learn more intuitively.

[0025] Example 2

[0026] See also Figures 1 to 5 , this embodiment further explains Example 1. In the figure, the rotating frame 406 is a U-shaped structure.

At the same time, the connected rotating device 4 inside the extended boss 3 on one side can lift or lower the patient's limbs according to the lifting rotating frame 406. When the rotating frame 406 is flipped, the main round teeth 403 and the secondary round teeth 404 are misaligned. Since the secondary round teeth 404 remain stationary on the connecting rod 401, the rotating main round teeth 403 will be engaged with the secondary round teeth 404, and the fastening nuts 402 fixed at both ends of the connecting rod 401 are rotated to tighten the fastening nuts 402 to keep the connecting rod 401 stable. The purpose of the spring 411 is that after the fastening nut 402 is loosened, the main round tooth 403 of the spring 411 is reset to make the rotating frame 406 return to a horizontal state. Since the upper and lower sides of the rotating frame 406 are provided with sliding grooves 407, a demonstration bed 408 is slidably clamped inside the sliding groove 407. The demonstration bed 408 is slidably connected to the top sliding groove 407 through the top clamping block 409. Therefore, during the sliding process, the demonstration bed 408 can rotate 360° with the clamping block 409 as a circle. During the flipping and translation process, when the angle is appropriate, the positioning knob 410 on the lower surface of the demonstration bed 408 is used to rotate and press against the rotating frame 406, thereby achieving a fixing effect.
