[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] An embodiment of the present invention provides an infusion monitor, as Figures 1-14 shown. The infusion monitor includes: a housing 1 for storing a plurality of infusion bottles and a plurality of sets of clamping blocks 2 provided in the housing 1 for fixing the infusion bottles; a weighing assembly 3 installed at the bottom of the housing 1, a liquid storage cylinder 4 is inserted on the housing 1 and the weighing assembly 3, and the weighing assembly 3 is used to weigh the weight of the liquid storage cylinder 4 and judge whether the infusion bottle is finished dripping according to the change in the weight of the liquid storage cylinder 4; an infusion set 5 inserted at the bottom of the liquid storage cylinder 4 for infusing the patient; an intubation tube 7 provided in the housing 1 for connecting the infusion bottle, a connecting tube 8 is installed on the intubation tube 7, and the connecting tube 8 is connected to the liquid storage cylinder 4; a warning device 39 installed at the bottom of the housing 1 for giving an alarm when the infusion bottle finishes dripping; and a moving mechanism provided in the housing 1 for driving the intubation tube 7 to automatically switch to the next infusion bottle.

[0036] In this embodiment, during operation, a number of infusion bottles are stored in the housing 1 and fixed by multiple sets of clamping blocks 2. The infusion bottles are connected to the liquid storage cylinder 4 through the infusion tube 7 and the connecting tube 8. The bottom of the liquid storage cylinder 4 is inserted with an infusion set 5 to infuse the patient. During the infusion process, the weighing assembly 3 (composed of an annular frame and a weighing sensor) continuously monitors the weight change of the liquid storage cylinder 4. When all the liquid medicine in the infusion bottle is discharged and no more liquid is supplied to the liquid storage cylinder 4, the liquid medicine in the liquid storage cylinder 4 will decrease due to continuous infusion to the patient. This weight change is monitored by the weighing assembly 3. Subsequently, the weighing assembly 3 triggers the moving mechanism to drive the infusion tube 7 to move and insert it into the next infusion bottle to achieve continuous infusion. In addition, before infusion, it is necessary to ensure that the liquid level of the liquid medicine in the liquid storage cylinder 4 is above two-thirds of the liquid storage cylinder 4 for the weighing assembly 3 to monitor. At the same time, when the liquid medicine in the liquid storage cylinder 4 has finished dripping, the alarm 39 will emit an alarm to prompt the patient and medical staff to perform subsequent processing;

[0037] By monitoring the weight change of the liquid storage cylinder 4 through the weighing assembly 3 and using the moving mechanism to automatically switch the infusion tube 7 to the next infusion bottle, the problem that the device is not easy to automatically perform the infusion operation of the next infusion bottle after the infusion is completed is solved, ensuring that the patient continuously receives infusion treatment and avoiding treatment interruption caused by the medical staff's failure to detect and replace the infusion bottle in time. By automatically switching the infusion bottle, the blood backflow or pressure change in the infusion system that may be caused by infusion interruption is avoided, reducing the possibility of causing unnecessary harm to the patient. By the alarm 39 emitting an alarm when the liquid in the liquid storage cylinder 4 has finished dripping, the medical staff are further reminded to pay attention to the infusion situation, enhancing the safety and reliability of the infusion process.

[0038] In a further preferred embodiment of the present invention, the moving mechanism includes: a support plate 6 provided in the housing 1, a notch is opened on one side of the support plate 6; a one-way screw 9 rotatably installed in the notch; a slider 10 threadedly sleeved on the one-way screw 9, the slider 10 is in sliding contact with one side of the notch; a threaded sleeve 11 fixedly installed on one side of the slider 10 and threadedly connected to the infusion tube 7; a connecting mechanism provided in the housing 1 for driving the one-way screw 9 to rotate.

[0039] In this embodiment, when adjusting the position of the cannula 7, the connection mechanism starts to operate first. Under the action of the connection mechanism, the cannula 7 will first move downward and away from the port of the current infusion bottle. Subsequently, the connection mechanism continues to function and drives the one-way screw 9 to rotate. Since the slider 10 is threadedly sleeved on the one-way screw 9 and the slider 10 is in sliding contact with one side of the notch of the support plate 6, when the one-way screw 9 rotates, it will drive the slider 10 to move along the axial direction of the one-way screw 9. Also, because a threaded sleeve 11 threadedly connected to the cannula 7 is fixedly installed on one side of the slider 10, the movement of the slider 10 will drive the cannula 7 to move through the threaded sleeve 11, thereby realizing the adjustment of the position of the cannula 7 so that it can be inserted into the next infusion bottle. Through the cooperation of the one-way screw 9, the slider 10 and the threaded sleeve 11, the moving distance and position of the cannula 7 can be quickly controlled to ensure that the cannula 7 can be accurately inserted into the next infusion bottle and guarantee the smooth progress of the infusion process. In addition, first, the connection mechanism is used to move the cannula 7 downward and away from the port of the current infusion bottle, and then the one-way screw 9 is driven to rotate to drive the cannula 7 to move. This orderly operation process can prevent the cannula 7 from interfering with the infusion bottle or other components during the movement, improving the stability and reliability of the device operation.

[0040] In a further preferred embodiment of the present invention, the connection mechanism includes: a partition plate 16 fixedly installed in the housing 1; an electric telescopic rod 12 fixedly installed on one side of the partition plate 16, and the electric telescopic rod 12 is fixedly connected to the support plate 6; a driven gear 13 fixedly sleeved on one end of the one-way screw 9; a support plate 14 fixedly installed on one side of the partition plate 16, and a rack 15 is provided on one side of the support plate 14, and the rack 15 meshes with the driven gear 13.

[0041] In this embodiment, when the weighing component 3 detects a change in the weight of the liquid storage cylinder 4 and transmits a signal to the controller 58, the controller 58 automatically activates the electric telescopic rod 12. After the electric telescopic rod 12 is activated, it drives the support plate 6 to move downward. Since the intubation tube 7 is associated with the support plate 6 (connected through the slider 10 and the threaded sleeve 11), the downward movement of the support plate 6 drives the intubation tube 7 to move downward, making it away from the port of the current infusion bottle. At the same time, the driven gear 13 fixedly sleeved at one end of the one-way screw rod 9 meshes with the rack 15 fixedly installed on one side of the support plate 14. While the intubation tube 7 moves downward away from the port, the driven gear 13 rotates along the rack 15, thereby driving the one-way screw rod 9 to rotate. Finally, the movement of the intubation tube 7 is realized to switch to the next infusion bottle. By the weighing component 3 transmitting a signal to the controller 58, the controller 58 automatically activates the electric telescopic rod 12, realizing the automation of the entire position adjustment process of the intubation tube 7, reducing manual operation, and improving work efficiency and accuracy. By the electric telescopic rod 12 driving the support plate 6 to move downward, and at the same time using the meshing relationship between the driven gear 13 and the rack 15, the downward movement of the support plate 6 is linked with the rotation of the one-way screw rod 9, completing two key steps of the downward movement and position adjustment of the intubation tube 7 in one action process, simplifying the operation process;

[0042] In addition, when it is necessary to replace the empty bottle in the housing 1, first turn the handle on one side of the one-way screw rod 9 to make the intubation tube 7 in the initial position, thereby facilitating subsequent infusion operations again.

[0043] In a further preferred embodiment of the present invention, a fixing mechanism for fixing the infusion bottle is provided in the housing 1. The fixing mechanism includes: a rectangular opening opened on the partition plate 16, and the rectangular opening is located on one side of the clamping block 2; a first bidirectional screw rod 17 rotatably installed on the left side of the partition plate 16; sliding plates 18 threadedly sleeved on the first bidirectional screw rod 17, and the sliding plates 18 penetrate through the rectangular opening and are fixedly connected to the clamping block 2; a handle 19 rotatably installed on one side of the housing 1; and tapered gears 20 fixedly sleeved on the handle 19 and the first bidirectional screw rod 17 respectively, and the two tapered gears 20 mesh with each other.

[0044] In this embodiment, when it is necessary to fix the infusion bottle, the medical staff manually rotates the handle 19. Since tapered gears 20 that mesh with each other are fixedly sleeved on the handle 19 and the first bidirectional screw 17 respectively, the rotation of the handle 19 will drive the first bidirectional screw 17 to rotate through the meshing transmission of the two tapered gears 20. When the first bidirectional screw 17 rotates, the two sliding plates 18 will approach or move away from each other along the axial direction of the first bidirectional screw 17, thereby driving the clamping block 2 to move, and clamping and fixing the infusion bottle through the movement of the clamping block 2. By utilizing the thread fit between the first bidirectional screw 17 and the sliding plate 18, and the movement clamping of the clamping block 2, stable and reliable fixation can be provided for the infusion bottle, preventing the infusion bottle from shaking or shifting during the infusion process and ensuring the smooth progress of the infusion process.

[0045] In a further preferred embodiment of the present invention, a support mechanism for supporting the infusion bag is provided on the partition plate 16. The support mechanism includes: a connection port 21 opened on the partition plate 16; a connecting rod 22 fixedly installed in the connection port 21; a connection block 23 slidably sleeved on the connecting rod 22; a hook 24 fixedly installed on one side of the connection block 23 for hanging the infusion bag; and an anti-slip sleeve 25 disposed in the connection block 23 and in close contact with the connecting rod 22.

[0046] In this embodiment, when fixing the infusion bag, first hang the hanging ring of the infusion bag on the hook 24. The medical staff can manually move the hook 24 up or down according to the length of the infusion bag, driving the connection block 23 to slide along the connecting rod 22. After adjusting to the appropriate height, the friction force generated by the close contact between the anti-slip sleeve 25 and the connecting rod 22 can prevent the connection block 23 from sliding randomly, so that the hook 24 is stabilized at the required height, more suitable for the infusion bag. Through the hook 24 with adjustable height, it can be flexibly adjusted according to infusion bags of different length specifications, making the infusion bag in a suitable position when hanging, ensuring the stability and safety of the infusion process, and improving the adaptability of the device to different infusion bags.

[0047] In a further preferred embodiment of the present invention, a limiting mechanism for limiting the infusion port of the infusion bottle and the infusion bag is provided in the housing 1. The limiting mechanism includes: a second bidirectional screw 26 rotatably installed in the housing 1; multiple groups of fixing blocks 27 all threadedly sleeved on the second bidirectional screw 26; connection springs 28 respectively installed on the multiple groups of fixing blocks 27; and U-shaped blocks 29 respectively installed at one end of the connection springs 28 for clamping the infusion port.

[0048] In this embodiment, first, place the infusion bottle and the infusion bag in appropriate positions so that their infusion ports are at preset fixed positions for subsequent limiting operations by the limiting mechanism. When it is necessary to limit the infusion port, rotate the second bidirectional screw 26 in the housing 1. The rotation of the second bidirectional screw 26 will drive multiple groups of fixing blocks 27 to approach or move away from each other along the axial direction of the second bidirectional screw 26. Utilize the elastic clamping action of the U-shaped block 29 to clamp the infusion port. The U-shaped structure of the U-shaped block 29 can limit the up-and-down movement of the infusion port. At the same time, the connecting spring 28 can provide a certain buffering and adaptation ability to ensure that when inserting or removing the cannula 7, the infusion bag and the infusion bottle will not move due to the force of the cannula 7. The setting of the connecting spring 28 enables the limiting mechanism to have a certain elastic buffering ability, which can adapt to infusion ports of different sizes and shapes, and can also absorb the external force generated when inserting or removing the cannula 7 to a certain extent, avoiding the displacement of the infusion bottle and the infusion bag due to the external force.

[0049] In a further preferred embodiment of the present invention, a guide rod 30 is slidably installed on the fixing block 27. The guide rod 30 penetrates through the connecting spring 28, and one end of the guide rod 30 is fixedly connected to the U-shaped block 29. A limiting plate is fixedly installed in the housing 1, and the limiting plate is in sliding contact with the top of the fixing block 27.

[0050] In this embodiment, when the second bidirectional screw 26 is rotated, since the fixing block 27 is threadedly sleeved on the second bidirectional screw 26 and the top of the fixing block 27 is in sliding contact with the limiting plate fixedly installed in the housing 1, under the limiting action of the limiting plate, the fixing block 27 will not rotate with the second bidirectional screw 26 but move along the axial direction of the second bidirectional screw 26. At the same time, a guide rod 30 is slidably installed on the fixing block 27. The guide rod 30 penetrates through the connecting spring 28 and one end is fixedly connected to the U-shaped block 29. During the movement of the fixing block 27, the guide rod 30 will guide the smooth movement of the U-shaped block 29 so that the U-shaped block 29 can accurately approach and clamp the infusion port.

[0051] In a further preferred embodiment of the present invention, a cover plate 31 is hinged to one side of the housing 1. One side of the inner wall of the cover plate 31 is fixedly installed with an L-shaped block 34. One side of the inner wall of the housing 1 is rotatably installed with a threaded rod 32. A threaded barrel 33 is sleeved on the threaded rod 32. The threaded barrel 33 is in sliding contact with the inner walls of the housing 1 and the cover plate 31. A rectangular groove is opened at the top of the threaded barrel 33, and the rectangular groove is slidably connected to the L-shaped block 34.

[0052] In this embodiment, after fixing the infusion bottle at the corresponding position in the housing 1 through the fixing mechanism (components such as the clamping block 2), the medical staff closes the cover plate 31. At this time, through the sprocket 35 and chain 36 transmission structure arranged in the housing 1, when the second bidirectional screw 26 is rotated, the threaded rod 32 will rotate synchronously with the second bidirectional screw 26. The rotation of the threaded rod 32 will drive the threaded cylinder 33 to move to one side along the axial direction of the threaded rod 32. At the same time, as the threaded cylinder 33 moves, the threaded cylinder 33 slides and is connected to the L-shaped block 34, so that the L-shaped block 34 is slidably connected to the rectangular groove, and the cover plate 31 is fixed.

[0053] In a further preferred embodiment of the present invention, sprockets 35 are fixedly sleeved on both the second bidirectional screw 26 and the threaded rod 32, and a chain 36 is sleeved on the two sprockets 35, and the chain 36 meshes with the two sprockets 35.

[0054] In this embodiment, when the second bidirectional screw 26 rotates, the sprocket 35 on it will rotate accordingly, and drive the sprocket 35 on the threaded rod 32 to rotate synchronously through the chain 36, so that the threaded rod 32 and the second bidirectional screw 26 achieve synchronous rotation. Through the transmission setting of the sprocket 35 and the chain 36, only a single operation of rotating the second bidirectional screw 26 can simultaneously complete the limitation of the infusion port and the fixation of the cover plate 31, greatly simplifying the operation process and improving the work efficiency.

[0055] In a further preferred embodiment of the present invention, an observation window 37 for observing the infusion condition of the infusion bottle is installed on the cover plate 31, a hanging ring 38 for hanging the housing 1 on a medical bracket is installed on the top of the housing 1, and a counterweight block 40 is installed on the bottom of the inner wall of the housing 1.

[0056] In this embodiment, the setting of the observation window 37 facilitates the medical staff to observe the infusion condition of the infusion bottle in real time, and can timely discover problems occurring during the infusion process, such as the liquid medicine is about to be finished, the infusion speed is abnormal, etc., so as to take corresponding measures in time. Through the design of the hanging ring 38, the infusion monitor can be quickly and conveniently hung on the medical bracket, and the operation is simple.

[0057] In order to further improve the use effect of the present device, in addition to the above-mentioned solutions, this solution also has the following embodiments:

[0058] In another embodiment of the present invention, a storage battery 41 for supplying power to the electric telescopic rod 12 is fixedly installed at the bottom of the housing 1; a storage mechanism for storing the infusion tube of the infusion device 5 is arranged at the bottom of the housing 1, and the storage mechanism includes: a self-locking bracket 42 fixedly installed on the outer shell of the storage battery 41; a connecting plate 43 hinged on the self-locking bracket 42; clamping blocks 44 for fixing the infusion tube and both installed on the connecting plate 43.

[0059] In this embodiment, during the infusion process, since the infusion tube of the infusion set 5 is usually relatively long and the housing 1 itself has a certain length, the excess infusion tube is likely to droop to the ground, posing a risk of being knocked down by pedestrians, which may affect the normal progress of the infusion.

[0060] To solve this problem, the storage mechanism provided at the bottom of the housing 1 is utilized. First, through the self-locking bracket 42 (a fastening bolt is installed at the hinge of the self-locking bracket 42, which can be adjusted at will and has stability), the connecting plate 43 is moved to a suitable position on one side of the infusion tube. At the same time, the self-locking bracket 42 is stretched as needed to adjust the position of the connecting plate 43. Then, the excess infusion tube is successively snapped into the clamping blocks 44 installed on the connecting plate 43, so that the infusion tube forms a serpentine pipeline on the connecting plate 43, thereby realizing the storage of the infusion tube. In addition, the battery 41 fixedly installed at the bottom of the housing 1 is used to supply power to the electric telescopic rod 12 to ensure the normal operation of the electric telescopic rod 12. Through the storage mechanism, the excess infusion tube can be effectively stored, preventing the infusion tube from drooping to the ground, making the infusion environment cleaner and more orderly, and reducing potential safety hazards caused by the disorder of the infusion tube, such as being tripped by pedestrians and the infusion tube being pulled.

[0061] In another embodiment of the present invention, the connecting plate 43 is composed of a storage part 431 and a heating part 432. An electric heating wire 45 for heating the liquid medicine in the infusion tube is installed in the heating part 432; a spring wire 46 is provided on one side of the connecting plate 43 and is electrically connected to the electric heating wire 45 and the battery 41. A controller 58 for regulating the electric heating wire 45 is fixedly installed on one side of the battery 41.

[0062] In this embodiment, in a low-temperature environment such as winter, the temperature of the liquid medicine in the infusion bottle is relatively low. Directly inputting it into the patient's body will cause discomfort to the patient. At this time, the medical staff operates the controller 58 to start the electric heating wire 45 installed in the heating part 432. Since the electric heating wire 45 is electrically connected to the battery 41 through the spring wire 46, the battery 41 provides electrical energy for the electric heating wire 45 to make it start working and generate heat. At the same time, the heating temperature of the electric heating wire 45 can be regulated through the controller 58, so that the electric heating wire 45 generates appropriate heat to heat the infusion tube wound around the heating part 432 of the connecting plate 43, and then heats the liquid medicine in the infusion tube, raising the temperature of the liquid medicine to a suitable temperature for the patient to input. Since the connecting plate 43 is composed of the storage part 431 and the heating part 432, the storage part 431 can store and organize the infusion tube, the heating part 432 is used to heat the liquid medicine, and the design of the spring wire 46 not only ensures the connection of the wire but also will not be damaged by being pulled due to the movement of the connecting plate 43. The overall structure is reasonable and practical.

[0063] In another embodiment of the present invention, a round rod 47 is slidably sleeved on the support plate 14. The round rod 47 is fixedly connected to one side of the rack 15. A return spring 48 is installed on the support plate 14 and the rack 15. One side of the partition plate 16 is fixedly installed with a mounting plate 49. A connecting rod 50 is inserted into the mounting plate 49. A pulling rope 51 is fixedly installed at the bottom end of the connecting rod 50. The pulling rope 51 passes through the mounting plate 49 and the support plate 14. One end of the pulling rope 51 is fixedly connected to the rack 15. A plurality of guide wheels for guiding the pulling rope 51 are fixedly installed on both the mounting plate 49 and the support plate 14.

[0064] In this embodiment, during the operation of the infusion monitor, when the support plate 6 moves downward, it will drive the cannula 7 to perform corresponding position adjustment. When the support plate 6 moves upward, it will pull the pulling rope 51 to move. The movement of the pulling rope 51 will drive the rack 15 to move. When the rack 15 moves, it will compress the return spring 48. After the rack 15 moves away from the driven gear 13, in the process of the support plate 6 moving upward, the driven gear 13 will not rotate due to the action of the rack 15, thereby preventing the cannula 7 from returning to its original position and ensuring the stability of the position of the cannula 7. Through the mechanism of driving the rack 15 away from the driven gear 13 by the pulling rope 51, it effectively prevents the cannula 7 from returning to its original position when the support plate 6 moves upward, ensuring the accuracy and stability of the position of the cannula 7 during infusion.

[0065] In another embodiment of the present invention, a cross plate 52 is fixedly installed at the bottom of the support plate 6. A group of elastic steel plates 53 for fixing the connecting rod 50 are installed at the bottom of the cross plate 52. A group of the elastic steel plates 53 are respectively clamped into a group of card slots of the connecting rod 50.

[0066] In this embodiment, during the downward movement of the support plate 6, the cross plate 52 moves downward synchronously with the support plate 6. The elastic steel plate 53 will gradually approach the connecting rod 50 and insert into a corresponding group of card slots on the connecting rod 50 to realize the connection between the elastic steel plate 53 and the connecting rod 50. When the support plate 6 moves upward, since the elastic steel plate 53 is stuck in the card slot of the connecting rod 50, the support plate 6 will drive the elastic steel plate 53 to move upward through the cross plate 52, thereby driving the connecting rod 50 to move. The movement of the connecting rod 50 will pull the pulling rope 51. The pulling rope 51 moves under the guidance of the guide wheels on the mounting plate 49 and the support plate 14, thereby driving the rack 15 to move, so that the rack 15 moves away from the driven gear 13, preventing the driven gear 13 from rotating when the support plate 6 moves upward and avoiding the cannula 7 from returning to its original position.

[0067] In another embodiment of the present invention, a connecting block 54 is fixedly installed on one side of the support plate 6. A U-shaped plate 55 is fixedly installed on one side of the rack 15. The U-shaped plate 55 is slidably connected to the connecting block 54.

[0068] In this embodiment, the process of the support plate moving upward: When the support plate 6 moves upward, the pull rope 51 pulls the rack 15 to move. The rack 15 drives the U-shaped plate 55 to move to one side together. At the same time, the support plate 6 drives the driven gear 13 and the connecting block 54 located on one side of the driven gear 13 to move upward. Since the teeth of the rack 15 are mainly distributed at the central position, and there are no teeth on some upper and lower sides, and the length of the U-shaped plate 55 is the same as the length of the distribution of several teeth. At this time, the rack 15 moves away from the driven gear 13 and does not drive the driven gear 13 to rotate. When the rack 15 moves to a specified position on one side, the elastic steel plate 53 disengages from the connecting rod 50. Under the action of the return spring 48, the rack 15 resets. However, due to the setting of the connecting block 54, the connecting block 54 limits the U-shaped plate 55, thereby restricting the reset position of the rack 15, so that the rack 15 does not mesh with the driven gear 13. When the connecting block 54 continues to slide upward and away from the U-shaped plate 55, the return spring 48 releases elastic force to make the rack 15 reset.

[0069] The process of the driven gear 13 moving downward: When the driven gear 13 moves downward through the electric telescopic rod 12, the connecting block 54 is inserted into the U-shaped plate 55 and slides along the U-shaped plate 55. At this time, the connecting block 54 limits the rack 15 to prevent the rack 15 from retreating, ensuring that the driven gear 13 and the rack 15 can mesh smoothly and ensuring the normal progress of the transmission process.

[0070] In another embodiment of the present invention, a group of limiting rods 56 are fixedly installed on the top of the mounting plate 49. The limiting rods 56 are composed of an upper outer inclined rod, a middle vertical rod, and a lower inner inclined rod. A limiting ring 57 is fixedly installed on one side of the elastic steel plate 53. The limiting ring 57 is located below the limiting rod 56, and the limiting ring 57 is adapted to the limiting rod 56.

[0071] In this embodiment, during the upward movement of the support plate 6, the elastic steel plate 53 moves upward synchronously with the support plate 6, and at the same time drives the limit ring 57 fixed on one side of it to move upward. When the limit ring 57 moves upward and contacts the limit rod 56, since the limit rod 56 is composed of an upper outer inclined rod, a middle vertical rod, and a lower inner inclined rod, the limit ring 57 will first contact the lower inner inclined rod. The inclined structure of the lower inner inclined rod will generate an outward component force on the limit ring 57, causing the limit ring 57 to drive the elastic steel plate 53 to move outward, and then deforming the elastic steel plate 53. When the limit ring 57 moves to the position of the middle vertical rod, at this time the elastic steel plate 53 has completely moved out of the card slot of the connecting rod 50, realizing the separation of the elastic steel plate 53 from the connecting rod 50. In addition, a notch is provided on the limit ring 57, and this notch is adapted to the rod body of the limit rod 56. Therefore, when the limit ring 57 moves up and down along the limit rod 56, it will not be blocked by the limit rod 56 and can move smoothly. Through the cooperation of the limit rod 56 and the limit ring 57, when the support plate 6 moves up to a specific position, the elastic steel plate 53 can be accurately separated from the connecting rod 50, ensuring the accuracy and reliability of the actions of each component during the entire transmission process.
