Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1: Please refer to Figure 1 - Figure 5 The cam 2 is a device for adjusting the angle of the limbs of the patient and the limbs of the patient, and the cam 2 is a device for adjusting the angle of ...

[0026] The rotating structure includes a fixed frame 6, a rotating shaft 601 is fixedly installed inside the fixed frame 6, a rotating frame 602 for driving a group of bottom plates 2 to rotate is rotatably installed on the outer surface of the rotating shaft 601, the rotating shaft 601 passes through one end of the fixed frame 6 and is fixedly connected to a rotating block 603, and a self-locking structure for locking the rotating shaft 601 to prevent it from rotating at will is fixedly installed on the outer surface of the rotating shaft 601 close to the rotating block 603;

[0027] Specifically, the fixed frame 6 is fixedly installed on the bottom surface of one group of bottom plates 2 and is fixedly connected to the support frame 1 through a connecting rod 7 fixedly installed on one side thereof. The rotating frame 602 is fixedly connected to the bottom surface of another group of bottom plates 2. The rotating frame 602 is connected to the rotating shaft 601 to drive the other group of bottom plates 2 to rotate accordingly, thereby assisting the patient to bend his limbs and completely unfold the wound.

[0028] The self-locking structure includes a fixed sleeve 604, which is rotatably mounted on the outer surface of the rotating shaft 601, and a cone sleeve 605 for clamping the limit rotating block 603 is slidably mounted inside the fixed sleeve 604, and a clamping groove is provided on the side of the cone sleeve 605 close to the rotating block 603, and a clamping block 606 for clamping with the cone sleeve 605 is clamped inside the clamping groove, and the clamping block 606 is fixedly mounted on one side of the rotating block 603;

[0029] Specifically, a sliding groove for providing sliding of the cone sleeve 605 is provided inside the fixed sleeve 604, and the cone sleeve 605 is located in the sliding groove, and a spring 607 for providing sliding power for the cone sleeve 605 is fixedly installed in the gap between the cone sleeve 605 and the inner wall of the fixed sleeve 604;

[0030] More specifically, the slot is provided with a "V"-shaped groove, and the shape of the block 606 is set to be a pyramid, and its outer wall fits with the slot to generate friction. The spring 2 607 supports the cone sleeve 605, and friction is formed between the cone sleeve 605 and the block 606 to achieve locking of the rotating shaft 601, preventing the rotating shaft 601 from rotating at will, driving the base plate 2 to rotate excessively, pulling the patient's wound, and causing secondary injury to the patient. When the base plate 2 needs to rotate, the rotating block 603 is twisted to drive the rotating shaft 601 to rotate, and a part of the axial thrust is formed at the slot of the cone sleeve 605, driving the cone sleeve 605 and the fixed sleeve 604 to rotate. The rotational force is greater than the push of the spring 2 607, thereby being able to control the rotation of the rotating shaft 601 again, and then easily unlocking the locking of the rotating shaft 601.

[0031] A rack 608 is fixedly installed inside the fixed frame 6 and the rotating frame 602. A gear 609 is rotatably installed at the bottom end of the base plate 2 to drive the base plate 2 to move, and the gear 609 is meshed with the upper surface of the rack 608. Specifically, the gear 609 is rotatably connected to the inner wall of the base plate 2 through a rotating shaft fixedly installed inside it. The gear 609 rotates along the rack 608 to drive the base plate 2 to move left and right, so as to adjust the distance between the two groups of base plates 2, thereby ensuring that the device better meets the patient's usage needs and preventing the clamp ring 3 from pressing on other affected parts of the patient.

[0032] Example 2: Please refer to Figure 6 The limiting structure includes a limit block 8, which is fixedly installed on the bottom surface of the pressing plate 4. A push block 801 is slidably installed inside the bottom plate 2, and the push block 801 and the limit block 8 fit each other. Both ends of the push block 801 are fixedly connected with a spring 802 for driving the push block 801 to reset. A push rod 803 for pushing the push block 801 to move is fixedly installed on one side of the push block 801.

[0033] Specifically, a limiting groove for clamping the limiting block 8 is provided inside the bottom plate 2, and a protruding block is provided on one side of the limiting block 8. The limiting block 8 is made of plastic and has a certain degree of softness, so that when the pushing block 801 pushes the limiting block 8, the protruding block on one side of the limiting block 8 can be retracted, thereby facilitating the unlocking of the pressing plate 4.

[0034] The inner wall of the bottom plate 2 is provided with a square groove for providing movement of the push block 801, and the push block 801 is located in the square groove. One end of the push rod 803 extends to the outside of the bottom plate 2 and is fixedly installed with a positioning plate 804 for preventing the push rod 803 from excessive movement.

[0035] See also Figure 7An axle rod 9 is fixedly installed inside the clamp ring 3, and both sides of the axle rod 9 pass through the clamp ring 3 and are rotatably installed with moving blocks 901, which are slidably clamped inside the base plate 2, and a spring four 902 is fixedly installed on one side of the moving block 901, and the spring four 902 is fixedly connected to the base plate 2; specifically, the patient places the limbs in the clamp ring 3, and then pushes the clamp ring 3 to drive the moving block 901 to squeeze the spring four 902, thereby expanding the internal space of the clamp ring 3. Conversely, the spring four 902 can also push the clamp ring 3 to contract inward, thereby ensuring that the clamp ring 3 fits the patient's limbs better.

[0036] See also Figure 1 - Figure 2 , Figure 6 A plurality of sets of universal wheels 10 for driving the entire device to move are fixedly installed at the bottom end of the support frame 1, and a soft pad 11 for enhancing the comfort of the device is fixedly installed on the upper surface of the pressing plate 4, and the material of the soft pad 11 is set to be silicone.

[0037] The working principle of the utility model is:

[0038] First, pull the bottom plate 2 to drive the gear 609 to move along the rack 608, adjust the distance between the two sets of bottom plates 2 according to the actual situation of the patient, and then let the patient place his limbs on the surface of the cushion 11, use the weight of the limbs to press the pressing plate 4 to squeeze the contraction spring 5, and insert the limit block 8 into the bottom plate 2, so that the pressing plate 4 presses the clamp ring 3 to rotate and merge around the shaft 9 to fix the patient's limbs. At the same time, the limbs themselves squeeze the clamp ring 3 to drive the moving block 901 to squeeze the spring four 902 to expand the internal use space of the clamp ring 3, and then rotate the rotating block 603 to connect the rotating The shaft 601 drives the rotating frame 602 to control a group of base plates 2 to drive the patient's limbs to rotate, so as to expose and unfold the wound. At the same time, after the rotating block 603 stops rotating, the spring 2 607 pushes the cone sleeve 605 and the clamping block 606 to engage with each other, limiting the rotation of the rotating block 603, and then supporting and fixing the base plate 2, so as to facilitate the dressing change for the patient. Finally, by pressing the push rod 803 to squeeze the spring 3 802, the pushing block 801 pushes the limit block 8, thereby releasing the lock on the pressing plate 4 and loosening the clamp ring 3, making it convenient for the patient to leave the device.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
