[0041] In addition, referring to Figure 3 An annular groove 12 is formed on the inner wall of the first mounting ring 11 along the circumference of the first mounting ring 11, an annular block 13 is slidably arranged in the annular groove 12, the annular block 13 can make circumferential movement in the annular groove 12 along the circumference of the first mounting ring 11, a second mounting ring 14 is fixedly installed on the inner side of the annular block 13, and the second mounting ring 14 is coaxially and rotationally connected with the first mounting ring 11.
[0042] Referring to Figure 3 A rotating hole 15 is formed on the inner wall of the second mounting ring 14 along the radial direction of the second mounting ring 14, as an embodiment of the present application, two rotating holes 15 are formed, and the two rotating holes 15 are symmetrically arranged along the axis of the second mounting ring 14, Figure 3Only one of the rotation holes 15 is shown, and the other rotation hole 15 is hidden on the opposite side. A mounting shaft 16 is rotatably mounted in each rotation hole 15, and a fixed ring 17 is fixedly mounted on the end of the mounting shaft 16 away from the rotation hole 15, that is, the fixed ring 17 is connected to the inner end of the mounting shaft 16 protruding out of the rotation hole 15 on the second mounting ring 14. The outer diameter of the fixed ring 17 is smaller than the inner diameter of the second mounting ring 14, and the fixed ring 17 can rotate along the axis of the two mounting shafts 16, that is, the fixed ring 17 can swing left and right in the second mounting ring 14. A through hole 18 is formed through the fixed ring 17 in the axial direction of the fixed ring 17, and the through hole 18 is used for the drainage tube to pass through. A limiting piece 2 is arranged on the fixed ring 17, and the limiting piece 2 is used to limit the position of the fixed ring 17 on the first mounting ring 11.
[0043] Referring to Figure 4 , 5 The limiting piece 2 is arranged as a limiting pin, and a mounting hole 21 is formed in the outer peripheral wall of the fixed ring 17 in the radial direction of the fixed ring 17. The limiting piece 2 is slidingly arranged in the mounting hole 21. A limiting hole 22 is formed in the inner wall of the first mounting ring 11 for the limiting piece 2 to insert into, and the limiting hole 22 corresponds to the mounting hole 21. A driving piece 6 is arranged on the fixed ring 17, and the driving piece 6 is used to drive the limiting piece 2 to move up and down in the mounting hole 21.
[0044] Referring to Figure 4 , 5 A receiving cavity 3 is formed in the fixed ring 17, and a first rotation shaft 31 and a second rotation shaft 32 are rotatably arranged in the receiving cavity 3. The axes of the first rotation shaft 31 and the second rotation shaft 32 are perpendicular to each other, and the first rotation shaft 31 is located below the second rotation shaft 32. A worm gear 33 is coaxially fixedly sleeved on the first rotation shaft 31, and a worm 34 is coaxially fixedly sleeved on the second rotation shaft 32. The worm gear 33 is meshed with the worm 34, and the worm 34 is in transmission connection with the limiting piece 2. An elastic piece 35 is sleeved on the first rotation shaft 31.
[0045] In this embodiment, the unwinding spiral angle of the worm 34 is smaller than the friction angle at which the worm gear 33 contacts the worm 34, so that the transmission between the worm gear 33 and the worm 34 has self-locking property, that is, only the worm 34 can drive the worm gear 33 to rotate, and the worm gear 33 cannot drive the worm 34 to rotate.
[0046] Referring to Figure 5 As an embodiment of the present application, the elastic piece 35 is arranged as a torsion spring, and the elastic piece 35 is sleeved on the first rotation shaft 31. One end of the elastic piece 35 is fixedly connected to the side wall of the worm gear 33, and the other end is fixedly connected to the inner wall of the receiving cavity 3. Figure 5As shown, in normal state, the worm wheel 33 rotates clockwise to drive the torsion spring 35 to store energy, when the worm wheel 33 rotates clockwise to the set position, the torsion spring 35 stores the set elastic potential energy, at this time, the limiting piece 2 is located in the limiting hole 22, and the elastic piece 35 has the kinetic tendency to drive the worm wheel 33 to rotate counterclockwise.
[0047] Referring to Figure 5 The accommodating hole 4 is arranged at the bottom of the mounting hole 21, one end of the second rotating shaft 32 penetrates the side wall of the accommodating cavity 3 and extends into the accommodating hole 4, the gear 41 is coaxially fixed on one end of the second rotating shaft 32 located in the accommodating hole 4, and the rack 42 is fixedly arranged at the bottom of the limiting piece 2 along the length direction of the limiting piece 2 and engaged with the gear 41.
[0048] In actual use, when it is needed to remove the limitation of the limiting piece 2 on the position of the fixing ring 17 on the first mounting ring 11, the driving piece 6 drives the limiting piece 2 to move away from the limiting hole 22, as shown, at this time, with the downward movement of the limiting piece 2, the rack 42 on the limiting piece 2 drives the second rotating shaft 32 to rotate clockwise, and further drives the worm 34 to rotate clockwise, the clockwise rotating worm 34 drives the worm wheel 33 to rotate counterclockwise, with the counterclockwise rotation of the worm wheel 33, the elastic piece 35 releases the elastic potential energy, and further enables the worker to use smaller force to drive the limiting piece 2 to move downward, so as to be separated from the limiting hole 22, to remove the limitation of the limiting piece 2 on the position of the fixing ring 17 on the first mounting ring 11. Figure 5 When it is needed to drive the limiting piece 2 into the limiting hole 22, the driving piece 6 drives the limiting piece 2 to move upward, the rack 42 on the limiting piece 2 drives the second rotating shaft 32 to rotate counterclockwise, and further drives the worm 34 to rotate counterclockwise, the counterclockwise rotating worm 34 drives the worm wheel 33 to rotate clockwise, at this time, the elastic piece 35 is compressed under force to generate elastic potential energy and prevent the clockwise rotation of the worm wheel 33, so that the worker needs to use larger force to drive the limiting piece 2 to move upward, i.e. to move away from the mounting hole 21, and further can prompt the worker.
[0049] Due to the self-locking effect of the worm wheel 33 and the worm 34, even if the limiting piece 2 is located in the limiting hole 22 and the elastic piece 35 is compressed under force, the worm wheel 33 cannot drive the worm 34 to deflect, and further cannot drive the limiting piece 2 to move away from the limiting hole 22.

[0051] Figure 6 A guide groove 5 is formed in the side wall of the mounting hole 21 along the height direction of the limiting piece 2, a guide block 51 is slidably arranged in the guide groove 5, the guide block 51 is fixedly connected with the side wall of the limiting piece 2, and a sliding layer is arranged on the surface of the guide block 51 and slidably connected with the inner wall of the guide groove 5.
[0052] During the movement of the limiting piece 2, the limiting piece 2 drives the guide block 51 to move in the guide groove 5 along with the movement of the limiting piece 2, the guide block 51 is slidably connected with the inner wall of the guide groove 5, thereby playing a certain guiding role in the movement of the limiting piece 2, and the sliding layer can effectively reduce the friction between the guide block 51 and the inner wall of the guide groove 5, facilitating the movement of the guide block 51 and reducing the abrasion between the guide block 51 and the inner wall of the guide groove 5, thereby prolonging the service life of the device.
[0053] Referring to Figure 4 , 6 , the driving piece 6 is a driving block, the driving piece 6 is slidably arranged on the end face of the fixed ring 17, a connecting hole 61 is formed in the fixed ring 17 along the height direction of the limiting piece 2, the connecting hole 61 is in communication with the mounting hole 21, a connecting block 62 is slidably arranged in the connecting hole 61, one end of the connecting block 62 is fixedly connected with the driving piece 6, and the other end is fixedly connected with the limiting piece 2.
[0054] When the limiting piece 2 needs to be moved, the driving piece 6 is driven to move, the driving piece 6 drives the connecting block 62 to move up and down in the connecting hole 61, and then drives the limiting piece 2 to move up and down, thereby facilitating the operation and improving the reliability and practicality of the device in actual use.
[0055] Referring to Figure 4 , the anti-skid sticker 63 is arranged on the side of the driving piece 6 away from the fixed ring 17, and the surface of the anti-skid sticker 63 is provided with anti-skid lines 64. The anti-skid sticker 63 can effectively improve the surface friction of the driving piece 6, facilitate the movement of the driving piece 6, and avoid the phenomenon of slipping during the movement of the driving piece 6, thereby further improving the practicality.

[0057] The silica gel protective pad 7 can provide good protection for the skin of the patient, and since the silica gel has a certain water absorption performance, it can keep the contact surface with the skin of the patient dry during a long drainage process, thereby further improving the protection effect on the patient.
[0058] Referring to Figure 2 The restraint belt 1 is provided with an abutting portion 8 on one side thereof, which is used to abut against the skin of a patient, and a Velcro 9 is fixedly arranged at the end of the restraint belt 1.
[0059] In addition, referring to Figure 7 As an embodiment of the present application, a tapered sleeve 19 is coaxially fixedly arranged in the through hole 18, one end of the tapered sleeve 19 has a large opening diameter, the other end has a small opening diameter, and the material of the tapered sleeve 19 is a soft polymer material such as silicone with a certain elastic modulus. In the process of drainage, the drainage tube is inserted through the tapered sleeve 19, and the drainage tube is limited by the small diameter port of the tapered sleeve 19, which can effectively prevent the drainage tube from shaking in the through hole 18.
[0060] In actual use, when the drainage tube needs to be fixed, first, the binding belt 1 is fixed on the patient's body, the driving piece 6 is pressed downward, the driving piece 6 drives the limiting piece 2 to move downward through the connecting block 62, and then the top of the limiting piece 2 is separated from the limiting hole 22, at this time, the limiting of the limiting piece 2 to the position of the fixing ring 17 on the first mounting ring 11 is released, then the drainage tube is inserted through the through hole 18 formed in the fixing ring 17, and the position of the drainage tube in the through hole 18 is limited by the conical sleeve 19 to avoid the shaking of the drainage tube in the through hole 18, at this time, the abdominal cavity drainage operation can be performed, in this process, due to the action of the elastic piece 35 on the worm gear 33, the worm gear 33 has a counterclockwise rotation trend, then the worm gear 33 drives the worm 34, the gear 41 and the rack 42, and finally drives the limiting piece 2 to have a trend of keeping in the position of the mounting hole 21, which can effectively avoid the disengagement of the limiting piece 2 from the mounting hole 21, in the subsequent drainage process, the fixing ring 17 can be deflected around the axis of the mounting shaft 16 relative to the second mounting ring 14, and the second mounting ring 14 can rotate around the axis of the first mounting ring 11, and then the fixing ring 17 can be deflected by 360° relative to the first mounting ring 11, so that the axis direction of the fixing ring 17 can be effectively adapted to the body shape of the patient, when the patient's body position changes, the fixing ring 17 can automatically adjust itself to adapt to the change of the patient's body position, avoiding the leakage of the exudate due to the change of the patient's body position, and reducing the risk of wound infection of the patient, after the drainage is completed, the binding belt 1 is removed from the patient's body, the drainage tube is removed from the fixing ring 17, then the fixing ring 17 and the second mounting ring 14 are rotated to make the limiting hole 22 coincide with the mounting hole 21, then the driving piece 6 is pushed upward, the driving piece 6 drives the limiting piece 2 to move away from the mounting hole 21 through the connecting block 62, and finally the limiting piece 2 is inserted into the limiting hole 22, at this time, the position of the fixing ring 17 on the first mounting ring 11 can be limited, after the limitation is completed, due to the self-locking effect between the worm gear 33 and the worm 34, the worm gear 33 cannot drive the worm 34 to deflect, therefore, although the elastic piece 35 acts on the worm gear 33 to make the worm gear 33 have a counterclockwise rotation trend, the worm 34 cannot rotate, and then the rack 42 cannot be driven by the gear 41 to move in the vertical direction, and then the limiting piece 2 cannot be separated from the limiting hole 22.
