Description

Technical Field

[0001] The present application belongs to the technical field of medical equipment, and in particular relates to a connecting line restraint for a patient and an extracorporeal device. Background Art

[0002] Patients in operating rooms or intensive care units usually need to be connected to a variety of vital sign monitoring devices, oxygen tubes, infusion tubes and other pipelines. This results in a large number of pipelines around the patients, which in turn affects the medical staff's care of the patients or affects the medical staff's surgery on the patients. At the same time, because there are many pipelines around the patients, the pipelines may be entangled with each other, which increases the difficulty for medical staff to organize the pipelines, and the entanglement of the pipelines also poses certain safety hazards.

[0003] At present, in order to prevent the pipeline from affecting the medical staff's care for patients or surgery, to facilitate the medical staff to organize the pipeline and to avoid safety hazards, a pipeline organizing device has appeared on the market, which includes a fixing part and a clamping part arranged on the fixing part, wherein the cross-section of the fixing part is C-shaped and elastic, so that the fixing part can be clamped on the rod-like structure or the bedside under the action of its own elasticity, and the clamping part has an opening on the side away from the fixing part, so that the pipeline can enter the interior of the clamping part through the opening of the clamping part and be bound by the clamping part, so as to achieve the arrangement of the pipeline; however, since the fixing part is clamped on the rod-like structure or the bedside by its own elastic force, the connection stability between the fixing part and the rod-like structure or the bedside is poor, so that when the clamping part clamps more pipelines or the clamping part is vertically arranged, the clamping part may be separated from the clamped object or move downward along the clamped object, thereby affecting the arrangement effect of the pipeline or causing discomfort to the patient. Utility Model Content

[0004] The present application provides a connecting pipeline restraint for a patient and an extracorporeal device, so as to increase the stability of the connecting pipeline restraint on the pipeline, and at the same time avoid the occurrence of patient discomfort caused by the movement of the connecting pipeline restraint.

[0005] The technical solution adopted in this application is:

[0006] A connecting pipeline restraint for a patient and an extracorporeal device comprises a fixing member and a plurality of restraining members arranged on the fixing member, each restraining member has a through hole for the pipeline to pass through on the side away from the fixing member, the fixing member comprises a fixing part and a pressure-applying part, and the fixing part is clamped on the clamped object under the action of the pressure-applying part.

[0007] By adopting the above-mentioned technical scheme, when using the connecting pipeline restraint in the present application, the fixing part is first installed on the clamped object so that the fixing part is clamped on the clamped object under the action of the pressure-applying part to increase the connection stability between the fixing part and the clamped object, and then various pipelines are inserted into the restraint part through the through-port, and then the restraint part restrains the pipelines to make the pipelines around the patient regular, so as to avoid the situation where the pipelines are complicated and too many affect the medical staff's care or surgery on the patient, and at the same time avoid the situation where the pipelines are entangled with each other, so as to achieve the effect of facilitating the medical staff to manage and store various pipelines.

[0008] In the present application, a pressure piece is provided to increase the clamping force that the fixing part can apply to the clamped object, thereby avoiding relative movement between the fixing part and the clamped object, increasing the connection stability between the fixing part and the clamped object, and avoiding the patient's discomfort or safety hazards caused by the movement of the fixing part, thereby improving the patient's medical experience.

[0009] Optionally, a restraining plate is further included, and a plurality of restraining members are sequentially arranged on the restraining plate along the length direction of the restraining plate.

[0010] By adopting the above technical solution, since multiple restraints are arranged on the restraint plate in sequence along the length direction of the restraint plate, multiple restraints are arranged in sequence along the length direction of the restraint plate, so that an appropriate distance can be maintained between two adjacent restraints, so as to achieve the effect of facilitating medical staff to install the pipelines on the restraints, and at the same time, an appropriate distance is maintained between adjacent pipelines to further avoid the situation where adjacent pipelines will be entangled together, thereby further achieving the effect of facilitating medical staff to store and organize the pipelines.

[0011] Optionally, one of the constraint plate and the constraint member is provided with a slide groove, and the other of the two is provided with a slider that slidably cooperates with the slide groove.

[0012] By adopting the above technical solution, the detachable connection between the restraint and the restraint plate is achieved through the cooperation of the slider and the slide groove, so that the medical staff can adjust the number of restraints according to the number and type of pipelines to increase the flexibility of connecting the pipeline restraint. At the same time, the medical staff can adjust the restraint according to the position of the pipeline to minimize the pulling on the pipeline to ensure the comfort of the patient, and can avoid the occurrence of pipeline entanglement to the greatest extent, so as to further facilitate the medical staff to store and organize the pipeline.

[0013] Optionally, one of the side wall of the slider or the groove wall of the slide groove is provided with an elastic arm having a protrusion, and the other one is provided with a matching groove, and the protrusion cooperates with the matching groove to limit the movement of the restraint member.

[0014] By adopting the above technical solution, when assembling the restraint, the slider is first aligned with the slide groove, and then a pushing force is applied to the restraint in the direction of the slide groove so that the slider and the slide groove are matched together, and finally the protrusion is extended into the matching groove, and then the matching of the protrusion and the matching groove is used to limit the restraint to avoid the separation of the restraint and the restraint plate, thereby increasing the connection stability between the restraint and the restraint plate, and then increasing the restraint effect on the pipeline.

[0015] Optionally, the restraining member includes a restraining portion having the through opening and guide portions provided on both sides of the through opening, and a distance between the two guide portions gradually increases in a direction away from the through opening.

[0016] By adopting the above technical solution, when installing the pipeline into the restraint, the pipeline is first placed at the through-port, and then the pipeline is made to contact with the guide part, and then the pipeline is pressed to make the pipeline apply pressure to the guide part, and the two guide parts move in opposite directions away from each other, so that the guide part drives the restraint part to deform, thereby increasing the opening of the through-port, so that the pipeline enters the restraint part through the through-port, and then the restraint part restores its deformation and contacts with the surrounding side of the pipeline to realize the restraint of the pipeline. In this process, it is only necessary to press the pipeline, which reduces the difficulty of installing the pipeline into the restraint, thereby improving the installation efficiency of the pipeline, improving the efficiency of organizing and restraining the pipeline, and thereby improving the use experience of medical staff.

[0017] Optionally, two fixing parts are provided and are hinged to each other through a hinge shaft, and the pressure-applying part is a torsion spring sleeved on the hinge shaft, and both ends of the torsion spring act on the two fixing parts respectively, so that the two fixing parts have an idle state in which the ends contact each other and a clamping state in which the ends are separated from each other, and in the clamping state, the torsion spring undergoes elastic deformation.

[0018] By adopting the above technical solution, when the fixing piece is clamped on the clamped object, the two fixing parts are first pressed, and then the two fixing parts are moved from the idle state to the clamped state, the torsion spring is elastically deformed, and then the fixing piece is pushed to the peripheral side of the clamped object, and then the fixing part is released, the torsion spring gradually recovers the deformation, and the two fixing parts move towards each other under the action of the torsion spring, and finally the two fixing parts are pressed against the peripheral side of the clamped object to complete the clamping of the fixing piece on the peripheral side of the clamped object. In this process, it is only necessary to press the fixing part, thereby achieving the effect of facilitating the clamping of the fixing piece on the clamped object, thereby improving the user experience of medical staff.

[0019] Optionally, the fixing portion has a clamping cavity with an opening toward one side, the pressure-applying portion is a rod-shaped structure threadedly connected to the fixing portion, and the pressure-applying portion has a pressure-applying end extending into the clamping cavity through one side of the opening.

[0020] By adopting the above technical solution, when installing the fixing piece, the fixing piece is first moved toward the clamped object, and then the clamped object enters the clamping cavity through the opening, and then the pressure-applying part is rotated, so that the pressure-applying end moves in the direction close to the clamped object, and finally the pressure-applying end is pressed against the clamped object, and at the same time, the cavity wall of the clamping cavity opposite to the pressure-applying end is pressed against the clamped object under the action of the pressure-applying part, so as to complete the installation of the fixing piece on the clamped object. In this process, only the pressure-applying part needs to be operated, which also achieves the effect of facilitating the clamping of the fixing piece on the clamped object, and further increases the connection stability between the fixing piece and the clamped object.

[0021] Optionally, the pressure-applying end is provided with a contact piece, and a cross-sectional area of ​​the contact piece is larger than a cross-sectional area of ​​the pressure-applying portion.

[0022] By adopting the above technical solution, after the fixing part is installed on the clamped object, the pressure-applying end is pressed against the clamped object through the contact piece. Since the cross-sectional area of ​​the contact piece is larger than the cross-sectional area of ​​the pressure-applying part, the contact area between the pressure-applying part and the clamped object is increased, thereby further increasing the connection stability between the fixing part and the clamped object.

[0023] Optionally, the contact piece is rotatably connected to the pressure end, and the cavity wall of the clamping cavity opposite to the contact piece and the contact piece are both provided with elastic pads, and the opposite end surfaces of the two elastic pads are both recessed in directions away from each other.

[0024] By adopting the above technical solution, since the contact piece and the cavity wall of the clamping cavity opposite to the contact piece are both provided with elastic pads, the fixing piece is clamped to the clamped object through the elastic pads to increase the friction between the fixing piece and the clamped object, thereby further increasing the connection stability between the fixing piece and the clamped object; and, by recessing the opposite end faces of the two elastic pads in directions away from each other, if the cross-section of the clamped object is circular, the contact area between the elastic pads and the clamped object can be increased to ensure the connection stability between the fixing piece and the clamped object.

[0025] Optionally, it also includes a constraint plate and a rotating member, a plurality of the constraint members are arranged on the constraint plate, the rotating member includes a rotating rod arranged on one of the constraint plate and the fixed part and a connecting tube arranged on the other of the two, the rotating rod is provided with a rotating ball, the rotating ball extends into the connecting tube and can rotate relative to the connecting tube.

[0026] By adopting the above technical solution, since a rotating member is provided between the constraint plate and the fixing member, the constraint plate can be rotated relative to the fixing member, and after the fixing member is clamped on the clamped object, the constraint plate can be adjusted to change the position of the constraint member, thereby adjusting the constraint member to a more appropriate position, thereby increasing the flexibility of the connecting pipeline restraint. When adjusting the constraint plate, the constraint plate is rotated so that the connecting rod drives the rotating ball and the connecting pipe to rotate relative to each other, so as to achieve the change of the relative position of the constraint plate and the fixing member, so that the fixing member can be clamped in a variety of different positions, so as to avoid the situation where the constraint plate interferes with other objects.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0028] 1. The connecting pipeline restraint in the present application includes a fixing part and a plurality of restraining parts arranged on the fixing part, each restraining part has a passage for the pipeline to pass through on the side away from the fixing part, and the fixing part includes a fixing portion and a pressure-applying portion. The fixing portion is clamped on the clamped object under the action of the pressure-applying portion, thereby increasing the clamping force that the fixing portion can apply to the clamped object to avoid relative movement between the fixing part and the clamped object, increasing the connection stability between the fixing part and the clamped object, and at the same time avoiding the patient feeling discomfort due to the movement of the fixing part, so as to improve the patient's medical experience.

[0029] 2. The connecting pipeline restraint in the present application also includes a restraint plate, and multiple restraint parts are arranged on the restraint plate in sequence along the length direction of the restraint plate, so that the multiple restraint parts are arranged in sequence along the length direction of the restraint plate, so that an appropriate distance can be maintained between two adjacent restraint parts, so as to achieve the effect of facilitating medical staff to install the pipeline to the restraint part, and at the same time, an appropriate distance is maintained between adjacent pipelines to further avoid the situation where adjacent pipelines will be entangled together, thereby further achieving the effect of facilitating medical staff to store and organize the pipelines.

[0046] Reference Figures 1 to 7 , discloses a connecting pipeline restraint for a patient and an extracorporeal device, comprising a fixing member 1 and a plurality of restraining members 2 arranged on the fixing member 1, each restraining member 2 having a through hole 213 for the pipeline to pass through on a side facing away from the fixing member 1, the fixing member 1 comprises a fixing portion 11 and a pressure-applying portion 12, and the fixing portion 11 is clamped on a clamped object under the action of the pressure-applying portion 12.

[0047] When using the connecting pipeline restrictor in this application, first install the fixing part 1 on the object to be clamped, so that the fixing part 11 is clamped on the object to be clamped under the action of the pressing part 12, so as to increase the connection stability between the fixing part 1 and the object to be clamped. Then, various pipelines are snapped into the plurality of restricting parts 2 through the through port 213, and then the restricting parts 2 restrict the pipelines, so as to regularize the pipelines around the patient, so as to avoid the situation that the pipelines are complicated and excessive, which affects the medical staff's care for the patient or the performance of surgery. At the same time, the situation that the pipelines are wound around each other is avoided, so as to achieve the effect of facilitating the medical staff to manage and store various pipelines.

[0048] In this application, by setting the pressing member, the clamping force that the fixing part 11 can exert on the object to be clamped is increased, so as to avoid the relative movement between the fixing part 1 and the object to be clamped, increase the connection stability between the fixing part 11 and the object to be clamped, and at the same time avoid the situation that the patient feels uncomfortable and there are potential safety hazards due to the movement of the fixing part 1, so as to improve the patient's medical experience.

[0049] It should be noted that the object that the fixing part 1 in this application can clamp can be a rod-shaped structure or a bedside or other ward structure with a certain thickness.

[0050] In a preferred embodiment, referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , the connecting pipeline restrictor further includes a restricting plate 3, and a plurality of restricting parts 2 are sequentially arranged on the restricting plate 3 along the length direction of the restricting plate 3, and then the plurality of restricting parts 2 are sequentially arranged along the length direction of the restricting plate 3, so that an appropriate distance can be maintained between two adjacent restricting parts 2, so as to achieve the effect of facilitating the medical staff to install the pipeline on the restricting part 2. At the same time, an appropriate distance is maintained between adjacent pipelines, so as to further avoid the situation that adjacent pipelines are wound together, and further achieve the effect of facilitating the medical staff to store and organize the pipelines.

[0051] Further, referring to Figure 5 and Figure 6 , one of the restricting plate 3 and the restricting part 2 is provided with a sliding groove 31, and the other of the two is provided with a sliding block 211 that is slidably matched with the sliding groove 31, and then the medical staff can adjust the number of the restricting parts 2 according to the number and type of the pipelines, so as to increase the flexibility of the connecting pipeline restrictor. At the same time, the medical staff can adjust the restricting part 2 according to the position of the pipeline, so as to minimize the pulling of the pipeline, ensure the comfort of the patient, and can maximize the avoidance of the situation that the pipelines are wound together, so as to further facilitate the medical staff to store and organize the pipelines.

[0052] The present application does not specifically limit the location of the annular groove and the slider 211. Preferably, refer to Figure 6 The slider 211 is arranged on the side of the constraint member 2 close to the fixing member 1, and the slide groove 31 is arranged on the side of the constraint plate 3 away from the fixing member 1, so as to ensure the structural strength of the constraint member 2, thereby increasing the constraint effect of the constraint member 2 on the pipeline. In other embodiments, the slider 211 can also be arranged on the side of the constraint plate 3 away from the fixing member 1, and the slide groove 31 is arranged on the side of the constraint member 2 away from the fixing member 1.

[0053] The present application does not specifically limit the structure of the slider 211 and the slide groove 31. Preferably, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The cross-sectional shape of the slider 211 is wedge-shaped, and the slide groove 31 is set corresponding to the shape of the slider 211 to increase the connection stability between the constraint member 2 and the constraint plate 3. In other embodiments, the slider 211 can also be T-shaped in cross-sectional shape, and the slide groove 31 is set corresponding to the cross-sectional shape of the slider 211.

[0054] Further, refer to Figure 3 One of the side wall of the slider 211 or the groove wall of the slide groove 31 is provided with an elastic arm 312 having a protrusion 313, and the other of the two is provided with a matching groove 212, and the protrusion 313 cooperates with the matching groove 212 to limit the movement of the constraint 2.

[0055] The present application does not specifically limit the location of the elastic arm 312 and the matching groove 212. Preferably, refer to Figure 3 The elastic arm 312 is arranged on the groove wall of the slide groove 31, and the matching groove 212 is arranged on the side wall of the corresponding protrusion 313 arranged on the slider 211. The groove wall of the slide groove 31 is provided with an avoidance cavity 311 corresponding to the elastic arm 312, so that when the slider 211 moves to the position where the protrusion 313 is located, the slider 211 applies pressure toward the avoidance cavity 311 on the protrusion 313, and then the elastic arm 312 is deformed toward the avoidance cavity 311 under the action of the protrusion 313, so that the slider 211 can continue to slide relative to the slide groove 31, and when the matching groove 212 on the slider 211 moves to the position where the protrusion 313 is located, the elastic arm 312 recovers the deformation, so that the protrusion 313 cooperates with the matching groove 212 to realize the limitation of the slider 211, so as to avoid the slider 211 and the slide groove 31 from sliding relative to each other, so as to increase the connection stability between the constraint member 2 and the constraint plate 3.

[0056] In other embodiments, the elastic arm 312 may also be disposed on the slider 211 , and the protrusion 313 corresponding to the matching groove 212 is disposed on the groove wall of the sliding groove 31 .

[0057] In a preferred embodiment, referring to Figure 5 and Figure 6The restraining member 2 includes a restraining portion 21 having a through opening 213 and guide portions 22 disposed on both sides of the through opening 213 , and the distance between the two guide portions 22 gradually increases in a direction away from the through opening 213 .

[0058] Specifically, when installing the pipeline into the restraint 2, first place the pipeline at the through port 213, then make the pipeline contact with the guide portion 22, and then press the pipeline to make the pipeline apply pressure to the guide portion 22, and the two guide portions 22 move in opposite directions away from each other, so that the guide portion 22 drives the restraint portion 21 to deform, thereby increasing the opening of the through port 213, so that the pipeline enters the restraint portion 21 through the through port 213, and then the restraint portion 21 restores its deformation and contacts the surrounding side of the pipeline to realize the restraint of the pipeline. In this process, it is only necessary to press the pipeline, so as to reduce the difficulty of installing the pipeline into the restraint 2, thereby improving the installation efficiency of the pipeline, improving the efficiency of organizing and restraining the pipeline, and thereby improving the use experience of medical staff.

[0059] Preferably, the constraint portion 21 is a sheet structure with an arc-shaped cross-section, and the guide portion 22 is a sheet structure extending on both sides of the through opening 213 of the constraint portion 21 in a direction away from the fixing member 1, and the wall thickness of the constraint portion 21 remains the same along its own circumference to ensure the elastic deformation effect of the constraint portion 21, so as to achieve the effect of facilitating the installation of the pipeline into the constraint portion 21.

[0060] Preferably, the sizes of the plurality of restraining parts 21 are different, that is, the sizes of the internal spaces of the plurality of restraining parts 21 are different, so that the connecting pipeline restraint can restrain pipelines of various types and diameters to increase the restraining effect on the pipelines.

[0061] The present application does not specifically limit the structures of the fixing portion 11 and the pressure applying portion 12, and they may adopt any one of the following embodiments:

[0062] Embodiment 1. In this embodiment, referring to Figure 1 Two fixing parts 11 are provided and are hinged to each other through a hinge shaft. The pressure-applying part 12 is a torsion spring sleeved on the hinge shaft. Both ends of the torsion spring act on the two fixing parts 11 respectively, so that the two fixing parts 11 have an idle state in which the ends contact each other and a clamping state in which the ends are separated from each other. In the clamping state, the torsion spring undergoes elastic deformation.

[0063] Specifically, the two fixing parts 11 each include a clamping section and a connecting section arranged in the middle of the length direction of the clamping section, that is, the fixing part 11 is T-shaped, and the hinge shaft passes through the connecting section of the two fixing parts 11. The two ends of the torsion spring act on the two clamping sections respectively to increase the distance when the ends of the two fixing parts 11 are separated, so as to increase the range that the fixing part 11 can clamp.

[0064] It can be understood that when the fixing device 1 is clamped on the clamped object, the two fixing parts 11 are pressed first, and then the two fixing parts 11 are moved from the idle state to the clamped state, the torsion spring undergoes elastic deformation, and then the fixing device 1 is pushed to the peripheral side of the clamped object, and then the fixing part 11 is released, the torsion spring gradually recovers its deformation, and the two fixing parts 11 move toward each other under the action of the torsion spring, and finally the two fixing parts 11 are pressed against the peripheral side of the clamped object to complete the clamping of the fixing device 1 on the peripheral side of the clamped object. In this process, it is only necessary to press the fixing part 11, thereby achieving the effect of facilitating the clamping of the fixing device 1 on the clamped object, so as to improve the user experience of medical staff.

[0065] Implementation method 2. In this implementation method, refer to Figure 2 and Figure 4 The fixing portion 11 has a clamping cavity with an opening toward one side, and the pressure-applying portion 12 is a rod-shaped structure threadedly connected to the fixing portion 11 . The pressure-applying portion 12 has a pressure-applying end extending into the clamping cavity through one side of the opening.

[0066] Specifically, when installing the fixing member 1, the fixing member 1 is first moved toward the clamped object, and then the clamped object enters the clamping cavity through the opening, and then the pressure-applying portion 12 is rotated, so that the pressure-applying end moves in the direction close to the clamped object, and finally the pressure-applying end is pressed against the clamped object. At the same time, the cavity wall of the clamping cavity opposite to the pressure-applying end is pressed against the clamped object under the action of the pressure-applying portion 12, so as to complete the installation of the fixing member 1 on the clamped object. In this process, only the pressure-applying portion 12 needs to be operated, which also achieves the effect of facilitating the clamping of the fixing member 1 on the clamped object, and further increases the connection stability between the fixing member 1 and the clamped object.

[0067] In a preferred embodiment, referring to Figure 4 and Figure 6 The pressure end is provided with a contact piece 121, and the cross-sectional area of ​​the contact piece 121 is larger than the cross-sectional area of ​​the pressure portion 12. That is to say, the pressure end contacts the clamped object through the contact piece 121, thereby increasing the contact area between the pressure portion 12 and the clamped object, thereby further increasing the connection stability between the fixing member 1 and the clamped object.

[0068] Further, see Figure 4 and Figure 6The contact piece 121 is rotatably connected to the pressure end, and the cavity wall of the clamping cavity opposite to the contact piece 121 and the contact piece 121 are both provided with elastic pads 111, and the opposite end surfaces of the two elastic pads 111 are recessed in directions away from each other, so that the fixing member 1 is clamped to the clamped object through the elastic pads 111 to increase the friction between the fixing member 1 and the clamped object, thereby further increasing the connection stability between the fixing member 1 and the clamped object; and, by recessing the opposite end surfaces of the two elastic pads 111 in directions away from each other, if the cross-section of the clamped object is circular, the contact area between the elastic pads 111 and the clamped object can be increased to ensure the connection stability between the fixing member 1 and the clamped object.

[0069] In a preferred embodiment, referring to Figure 5 , Figure 6 and Figure 7 The connecting pipeline restraint also includes a restraint plate 3 and a rotating member 4. A plurality of restraint members 2 are arranged on the restraint plate 3. The rotating member 4 includes a rotating rod 41 arranged on one of the restraint plate 3 and the fixing portion 11 and a connecting tube 42 arranged on the other of the two. The rotating rod 41 is provided with a rotating ball 411. The rotating ball 411 extends into the connecting tube 42 and can rotate relative to the connecting tube 42, thereby enabling the restraint plate 3 to rotate relative to the fixing member 1, so that after the fixing member 1 is clamped on the clamped object, the restraint plate 3 can be adjusted to change the position of the restraint member 2, thereby adjusting the restraint member 2 to a more suitable position, thereby increasing the flexibility of the connecting pipeline restraint. When adjusting the restraint plate 3, the restraint plate 3 is rotated so that the connecting rod drives the rotating ball 411 to rotate relative to the connecting tube 42, so as to achieve the change of the relative position of the restraint plate 3 and the fixing member 1, so that the fixing member 1 can be clamped in a variety of different positions to avoid the situation where the restraint plate 3 interferes with other objects.

[0070] The present application does not specifically limit the location of the rotating rod 41 and the connecting tube 42. Figure 5 and Figure 6 The rotating rod 41 is disposed on the restraining plate 3, and the connecting pipe 42 is disposed on the fixing portion 11, so as to reduce the weight of the restraining plate 3 and thereby increase the stability of the restraining plate 3. In other embodiments, the rotating rod 41 may be disposed on the fixing portion 11, and the connecting pipe 42 may be disposed on the restraining plate 3.

[0071] Further, see Figure 5 , Figure 6 and Figure 7 The inner wall of the connecting tube 42 is provided with a limiting protrusion 421 located on the peripheral side of the rotating ball 411 to prevent the rotating ball 411 from separating from the connecting tube 42, thereby increasing the connection stability between the rotating rod 41 and the connecting tube 42.

[0072] Further, see Figure 5 , Figure 6 and Figure 7 The connecting tube 42 is provided with a separation groove 422, which penetrates the end of the connecting tube 42 away from the fixing portion 11, so that when the rotating ball 411 is installed in the connecting tube 42, the connecting tube 42 can undergo a large deformation, thereby achieving the effect of facilitating the installation of the rotating ball 411 in the connecting tube 42.

[0073] Further, refer to Figure 5 and Figure 6 The outer sleeve of the rotating rod 41 is provided with a fixing cover 412, and the fixing cover 412 is threadedly connected to the connecting tube 42 to increase the stability of the connecting tube 42 and avoid the situation where the rotating ball 411 is easily separated from the connecting tube 42 due to the provision of the separation groove 422.

[0074] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0075] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0076] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
