Description

Technical Field

[0001] This application relates to the field of incubator technology, and more specifically, to an incubator and its temperature control system. Background Technology

[0002] An incubator is a device used to raise infants. Light can shine directly into the incubator, which is dry, soundproof, and automatically temperature-controlled. It has a large range of movement and no extra steps except for diapers. The baby can sleep and play inside, avoiding all adverse external stimuli and creating a suitable behavioral environment for children's development, thus nurturing healthy children in body and mind.

[0003] In related technologies, incubators are designed to facilitate infant care by medical staff. Their height is typically adjustable via adjustable support legs. However, the protective cover on the incubator usually requires manual opening, which is inconvenient for quick operation. Even if the cover can be opened electrically via a tilting or sliding mechanism on height-adjustable incubators, it still requires a separate drive component. Incubators already have many electrical components; adding more drive components would increase the circuitry. Therefore, finding a way to quickly open the incubator's height and cover without adding drive components or additional circuitry is a technical problem that needs to be solved.

Detailed Implementation

[0043] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0045] The following description, with reference to the accompanying drawings, describes an infant incubator and its temperature control system according to embodiments of this application.

[0046] Firstly, please refer to Figures 1 to 11 This application provides an incubator, including: an incubator assembly 100, an adjustable support leg assembly 200, a pin-connected three-output drive assembly 300, and an opening assembly 400.

[0047] Please see Figure 1 and Figure 2The incubator assembly 100 includes an incubator body 110, a cover 120, and a chassis 130. An adjustable support leg assembly 200 is mounted on the chassis 130. The incubator body 110 is fixedly connected to the top of the adjustable support leg assembly 200. The side wall of the cover 120 is hinged to the incubator body 110, and the cover 120 covers the upper side of the incubator body 110. A pin-connected three-output drive assembly 300 is mounted on the adjustable support leg assembly 200 and can drive the adjustable support leg assembly 200 to adjust its height. The upper end of the cover opening assembly 400 is hinged to the side wall of the cover 120 and can drive the cover opening assembly 400 to flip and open the cover 120. When the height of the incubator 110 needs to be adjusted, the pin connection at the drive opening assembly 400 on the pin-type three-output drive assembly 300 is released, putting it in a disengaged state. In this state, the pin-type three-output drive assembly 300 moves, but the opening assembly 400 does not move. At this time, the pin-type three-output drive assembly 300 drives the adjusting leg assembly 200 to adjust its length, thereby changing the height of the incubator 110. When the cover 120 needs to be opened or closed, the pin connection at the drive opening assembly 400 is released. Adjusting the pin connection at the adjustable leg assembly 200, so that it is in a disengaged state, allows the pin-connected three-output drive assembly 300 to move, while the adjustable leg assembly 200 remains stationary. At this time, the pin-connected three-output drive assembly 300 drives the cover opening assembly 400, which in turn drives the cover 120 to open and close. The height adjustment of the incubator 110 and the opening and closing of the cover 120 are both controlled by a single motor with simple manual assistance, allowing the incubator to switch between height adjustment and cover opening / closing functions, thus saving on circuitry and drive components. The adjustable leg assembly 200 includes two adjustable legs 210 and a support frame 220, with the support frame 220 located at the movable end of each of the two adjustable legs 210. The two adjustable legs 210 are fixed together by a support frame 220, which improves the strength and stability of the adjustable legs 210. The support frame 220 can support the pin-connected three-output drive assembly 300, which facilitates the arrangement of the pin-connected three-output drive assembly 300.

[0048] Please see Figure 3The adjustable support leg 210 includes a fixed cylinder 211, a movable cylinder 212, a fixed block 213, a first screw 214, and a first helical tooth 215. The fixed cylinder 211 is fixedly connected to both sides of the upper end of the chassis 130. The movable cylinder 212 is slidably inserted into the upper end of the fixed cylinder 211. The fixed block 213 is fixedly connected to the inside of the upper end of the fixed cylinder 211. The fixed block 213 extends into the movable cylinder 212 and slides along the side wall of the movable cylinder 212. The first screw 214 is rotatably connected to the movable cylinder 212. The first helical tooth 215 is fixedly sleeved on the upper end of the first screw 214. The first screw 214 is threaded through the fixed block 213. The pin-type three-output drive assembly 300 can drive the first helical tooth 215 to rotate. The pin-type three-output drive assembly 300 drives the first helical tooth 215 to rotate, and the first helical tooth 215 drives the first screw 214 to rotate. Through the threaded transmission between the first screw 214 and the fixed block 213, the height of the first screw 214 changes, and the position of the movable cylinder 212 slides along the fixed cylinder 211. The movable cylinder 212 drives the height of the incubator 110 to change, making it easier for medical staff to adjust the incubator 110 to a position that is easy to operate.

[0049] Please see Figure 4 The pin-connected three-output drive assembly 300 includes a drive component 310, a main pin-connected rotating shaft component 320, and a side pin-connected rotating shaft component 330. The drive component 310, the main pin-connected rotating shaft component 320, and the side pin-connected rotating shaft component 330 are all mounted on the support frame 220. The side pin-connected rotating shaft components 330 are located on both sides of the main pin-connected rotating shaft component 320. The drive component 310 is engaged with the main pin-connected rotating shaft component 320 via gears. The main pin-connected rotating shaft component 320 is engaged with the side pin-connected rotating shaft component 330 via gears. The end of the main pin-connected rotating shaft component 320 is engaged with the cover assembly 400 via gears. The end of the side pin-connected rotating shaft component 330 is engaged with the adjusting leg 210 via gears. The drive component 310 drives the main pin-type rotating shaft component 320 through the helical gear meshing principle. The main pin-type rotating shaft component 320 can drive the cover assembly 400. The main pin-type rotating shaft component 320 drives the side pin-type rotating shaft component 330 through the helical gear meshing principle. The side pin-type rotating shaft component 330 can drive the adjusting support leg 210.

[0050] Please see Figure 5The side-pin type rotating shaft component 330 includes a second rotating shaft 331, a connecting cylinder 332, a second base 333, a third rotating shaft 334, a second pin portion 335, a sixth helical tooth 336, and a seventh helical tooth 337. The second rotating shaft 331 is mounted on the upper side of the support frame 220 via the second base 333 and is rotatably connected to the second base 333. The connecting cylinder 332 is fixedly connected to one end of the second rotating shaft 331. The sixth helical tooth 336 is fixedly sleeved on the other end of the third rotating shaft 334. The main pin type rotating shaft component 320 is engaged with the sixth helical tooth 336 via gears. The third rotating shaft... 334 is mounted on the upper side of the support frame 220 via the remaining second base 333. The third rotating shaft 334 is rotatably connected to the second base 333. One end of the third rotating shaft 334 is inserted into the connecting cylinder 332. The second pin part 335 is provided on the outer wall of the connecting cylinder 332. The second pin part 335 can pass through the outer wall of the connecting cylinder 332 and be inserted into the third rotating shaft 334. The other end of the third rotating shaft 334 rotates through the adjusting leg 210. The seventh helical tooth 337 is fixedly sleeved on the third rotating shaft 334 and extends into one end of the adjusting leg 210. The seventh helical tooth 337 meshes with the adjusting leg 210. Pulling the second pin 335 out of the third rotating shaft 334 releases the pin lock between the third rotating shaft 334 and the connecting cylinder 332, disengaging their rotation. At this time, the third rotating shaft 334 does not rotate with the connecting cylinder 332, thereby releasing the drive of the driving member 310 on the adjusting leg 210. Conversely, if the second pin 335 is inserted into the third rotating shaft 334, the pin lock between the third rotating shaft 334 and the connecting cylinder 332 is performed, and the two rotate synchronously. At this time, the main pin-type rotating shaft member 320 drives the sixth helical tooth 336 to rotate through the helical tooth meshing principle. The sixth helical tooth 336 drives the second rotating shaft 331 and the connecting cylinder 332 to rotate. The third rotating shaft 334 rotates with the connecting cylinder 332, and the third rotating shaft 334 drives the seventh helical tooth 337 to rotate. The seventh helical tooth 337 drives the adjusting leg 210 to move through the helical tooth meshing principle.

[0051] Please see Figure 6 The driving component 310 includes a drive motor 311 and a second helical gear 312. The drive motor 311 is fixedly connected to the lower side of the support frame 220, and the output end of the drive motor 311 passes through the support frame 220. The second helical gear 312 is fixedly connected to one end of the drive motor 311 that passes through the support frame 220. When the drive motor 311 is started, it drives the second helical gear 312 to rotate. The second helical gear 312 drives the main pin-type rotating shaft 320 to rotate through the helical gear meshing principle.

[0052] Please see Figure 7The main pin type rotating shaft component 320 includes a hollow shaft 321, multiple first bases 322, a first rotating shaft 323, a first pin portion 324, a third helical tooth 325, a fourth helical tooth 326, and a fifth helical tooth 327. The hollow shaft 321 is mounted on the upper side of the support frame 220 via the first bases 322 and is rotatably connected to the first bases 322. The first rotating shaft 323 is mounted on the upper side of the support frame 220 via the remaining first bases 322 and is rotatably connected to the first bases 322. 23 is inserted into the hollow shaft 321. The first pin part 324 is provided on the outer wall of the hollow shaft 321. The first pin part 324 can pass through the outer wall of the hollow shaft 321 and be inserted into the first rotating shaft 323. The third helical tooth 325 and the fourth helical tooth 326 are respectively fixedly sleeved on the outer walls of both ends of the hollow shaft 321. The third helical tooth 325 meshes with the second helical tooth 312. The fourth helical tooth 326 meshes with the side pin type rotating shaft 330. The fifth helical tooth 327 is fixedly sleeved on the end of the first rotating shaft 323. The fifth helical tooth 327 meshes with the cover assembly 400.

[0053] Please see Figure 8 The cover assembly 400 includes a linkage box 410 and a first L-shaped connecting rod 420. The outer wall of the linkage box 410 is fixedly connected to the support frame 220. The fifth helical tooth 327 engages with the linkage box 410. The lower end of the first L-shaped connecting rod 420 is hinged to the linkage box 410. A hinge seat is provided on the side wall of the cover 120 near the hinge point. The upper end of the first L-shaped connecting rod 420 is hinged to the hinge seat. The drive motor 311 drives the second helical tooth 312 to rotate. The second helical tooth 312 drives the third helical tooth 325 to rotate through the helical tooth meshing principle. The third helical tooth 325 drives the hollow shaft 321 to rotate. The fourth helical tooth 326 rotates with the hollow shaft 321. The fourth helical tooth 326 drives the sixth helical tooth 336 to rotate through the helical tooth meshing principle. The first pin 324 is inserted into the first rotating shaft 323. At this time, the hollow shaft 321 and the first rotating shaft 323 are locked together and can rotate synchronously. When the first rotating shaft 323 moves, it drives the fifth helical tooth 327. The fifth helical tooth 327 drives the linkage box 410 through the helical tooth meshing principle. The linkage box 410 drives the lower end of the first L-shaped connecting rod 420 to descend or rise. The upper end of the first L-shaped connecting rod 420 drives the cover 120 to flip open and close. Conversely, if the first pin 324 is inserted out of the first rotating shaft 323, the rotation of the two is disengaged, and the control of the drive motor 311 on the opening and closing of the cover 120 is released.

[0054] Please see Figure 8In related technologies, the incubator uses a main pin-type rotating shaft to drive the linkage box and control the opening of the cover. However, the only support point of the opened cover is the hinge point on the first L-shaped connecting rod, resulting in a small support area. When the cover is subjected to pressure unexpectedly, it is easy to damage the cover or its hinge. Providing a support surface after the cover is opened, thereby increasing the support area, can effectively improve this problem. However, providing a support surface for the opened cover also requires a corresponding drive. Therefore, how to set up a support structure to provide support for the opened cover and how to use existing drive components to provide power to the support structure have become technical problems that need to be solved.

[0055] To address this technical problem, the inventors, through long-term practical research, solved it. Specifically, a support base 430 is hinged to the side wall of the incubator 110, and a second L-shaped connecting rod 440 is hinged to the outer wall of the support base 430. The linkage box 410 includes a linkage box 411, a second screw 412, a first slider 413, a third screw 414, a second slider 415, an eighth helical tooth 416, and a linkage rotating shaft 417. The linkage box 411 is fixedly connected to the side of the support frame 220 near the hinge point of the cover 120. The second screw 412 and the third screw 414 are both rotatably connected inside the linkage box 411. The third screw 414 is located on both sides of the second screw 412, and the top ends of the second screw 412 and the third screw 414 extend out of the linkage box 411. The eighth helical tooth 416 is fixedly sleeved on the second screw. The eighth helical tooth 416 at the top of the second screw 412 and the third screw 414 are respectively connected to the eighth helical tooth 416 at the top of the third screw 414 via the linkage shaft part 417. The first slider 413 is threadedly sleeved on the second screw 412. The side wall of the first slider 413 extends out of the linkage box 411 and slides along the outer side wall of the linkage box 411. The lower end of the first L-shaped connecting rod 420 is hinged to the side of the first slider 413 extending out of the linkage box 411. The second slider 415 is threadedly sleeved on the third screw 414. The side wall of the second slider 415 extends out of the linkage box 411 and slides along the outer side wall of the linkage box 411. The lower end of the second L-shaped connecting rod 440 is hinged to the side of the second slider 415 extending out of the linkage box 411. When the fifth helical tooth 327 rotates, it drives the eighth helical tooth 416 at the top of the second screw 412 to rotate through the helical tooth meshing principle. The second screw 412 rotates accordingly. The eighth helical tooth 416 at the top of the second screw 412 drives the eighth helical tooth 416 at the top of the third screw 414 to rotate through the linkage shaft part 417. The third screw 414 rotates accordingly. The second screw 412 drives the first slider 413 to slide along the outer wall of the linkage box 411 through the thread transmission principle. The third screw 414 drives the second slider 415 to slide along the outer wall of the linkage box 411 through the thread transmission principle. The first slider 413 and the second slider 415 move in opposite directions. 3. When the first L-shaped connecting rod 420 is pulled, the first L-shaped connecting rod 420 opens the cover 120. The second slider 415 pushes the second L-shaped connecting rod 440, which in turn pushes the support seat 430 to flip open until the support seat 430 supports the cover 120. The support seat 430 provides a support surface for the cover 120, increasing the support area of ​​the cover 120. This effectively reduces the problem of damage to the cover or its hinges when the cover is subjected to pressure unexpectedly. In addition, the support structure is powered by a drive motor, which enables the drive motor to achieve multiple functions (driving the adjusting legs, the cover, and the support structure).

[0056] Please see Figure 9The linkage shaft part 417 includes a fourth shaft 4171, a ninth helical tooth 4172, and a third base 4173. The fourth shaft 4171 is mounted on the top of the linkage box 411 via the third base 4173. The ninth helical teeth 4172 are fixedly sleeved on both ends of the fourth shaft 4171. The two ninth helical teeth 4172 respectively mesh with the eighth helical tooth 416 at the top of the second screw 412 and the eighth helical tooth 416 at the top of the third screw 414. The eighth helical tooth 416 drives the ninth helical tooth 4172 through the helical tooth meshing principle. The ninth helical tooth 4172 drives the fourth shaft 4171 to rotate. The fourth shaft 4171 drives another ninth helical tooth 4172, which drives the other ninth helical tooth 4172 through the helical tooth meshing principle.

[0057] Please see Figure 10 The support base 430 includes a support plate 431 and a reinforcing box 433. The support plate 431 has a placement groove 432. The reinforcing box 433 is fixedly connected to the outer wall of the support plate 431, and its outer wall is hinged to the side wall of the infant care box 110. The upper end of the second L-shaped connecting rod 440 is hinged to the outer wall of the reinforcing box 433. The support plate 431 provides a support surface for the cover 120, increasing the support area. Protrusions on the cover 120 fall into the placement groove 432, reducing the possibility of the support plate 431 releasing the protrusions and reducing the support area. A buffer pad 434 is fixedly connected to the side wall of the support plate 431. The buffer pad 434 protects the cover 120, reducing wear and pressure damage.

[0058] Please see Figure 11 In related technologies, the drive motor on the incubator drives the cover to flip open via a main pin-type rotating shaft. Simultaneously, the main pin-type rotating shaft can be disengaged to release the movement. The main pin-type rotating shaft drives the side pin-type rotating shaft, which in turn drives the adjusting legs to adjust the height of the incubator. This adjustment can also be released by disengaging the side pin. If the pins on the main pin-type and side pin-type rotating shafts are connected using only a pin shaft, firstly, manual alignment is required, which is inconvenient for quick connection; secondly, the pin shaft is easily lost if placed separately.

[0059] To solve the above technical problem, the present invention further adopts the following technical solution: the second pin part 335 includes a mounting plate 3351, a movable frame 3352, a pressure plate 3353, a compression spring 3354, and a folding pin 3355. The mounting plate 3351 is fixedly connected to the outer wall of the connecting cylinder 332. One end of each side of the movable frame 3352 slides through both ends of the mounting plate 3351. The pressure plate 3353 is fixedly sleeved on the end of the movable frame 3352 that passes through the mounting plate 3351. The compression spring 3354 is sleeved on both sides of the movable frame 3352. The two ends of the compression spring 3354 are respectively pressed against the mounting plate 3351 and the pressure plate 3353. The folding pin 3355 is hinged inside the movable frame 3352. The folding pin 3355 can pass through the outer wall of the connecting cylinder 332 and insert into the third rotating shaft 334. The connecting cylinder 332 can block the folded pin 3355. The first pin part 324 and the second pin part 335 have the same structure. When the first pin part 324 is performing the pinning operation, the folded pin 3355 is flipped over and inserted into the connecting cylinder 332. The compression spring 3354 presses down on the pressure plate 3353, and the pressure plate 3353 drives the movable frame 3352 to tighten. The folded pin 3355 presses down on the third rotating shaft 334. As the connecting cylinder 332 rotates, when the insertion hole on the third rotating shaft 334 and the folded pin 3355 are aligned, the folded pin 3355 automatically inserts into the third rotating shaft 334 under the elastic force of the compression spring 3354, completing the pin connection and locking between the third rotating shaft 334 and the connecting cylinder 332. This reduces the need for manual alignment and facilitates quick pin connection. After pulling out the first pin part 324 in the reverse order, the folded pin 3355 is folded up, and the connecting cylinder 332 blocks the folded pin 3355. At this time, it is not necessary to remove the folded pin 3355, reducing the possibility of the folded pin 3355 being lost.

[0060] Secondly, embodiments of this application also provide a temperature control system for an incubator, including an incubator, an input module, a calculation module, and a temperature control adjustment module.

[0061] The input module is used to receive the infant's vital signs parameters;

[0062] The calculation module, connected to the input module, is used to calculate the appropriate temperature value for infant care based on the received vital signs parameters.

[0063] The temperature control module, connected to the calculation module, is used to adjust the deviation between the actual temperature value and the suitable temperature value inside the incubator according to the suitable temperature value calculated by the calculation module, so that the deviation does not exceed the preset range.

[0064] The input module, calculation module, and temperature control module are all located inside the infant care unit 110. The temperature control module includes an MCU control unit, a temperature sensing unit, a PID control unit, and a heating unit. The MCU control unit is connected to both the temperature sensing unit and the PID control unit, and the PID control unit is connected to the heating unit.

[0065] Temperature sensing unit is used to collect the actual temperature value inside the incubator;

[0066] The MCU unit is used to acquire the appropriate temperature value and the actual temperature value inside the incubator collected by the temperature sensing unit, and to set the control parameters of the PID control unit based on the appropriate temperature value and the actual temperature value.

[0067] The PID control unit is used to drive the heating unit to work according to the control parameters; the heating unit is used to achieve temperature rise or fall control so that the deviation between the actual temperature value and the suitable temperature value in the incubator does not exceed the preset range.

[0068] This incubator temperature control system can calculate the appropriate temperature value for infant care based on the received vital signs parameters of the infant, and then adjust the actual temperature value inside the incubator to ensure that the deviation from the appropriate temperature value does not exceed the preset range. Compared with the existing technology that relies entirely on the experience of medical staff for adjustment, this improves the accuracy of the adjusted appropriate temperature.

[0069] Specifically, the working principle of the incubator and its temperature control system is as follows: When the height of the incubator body 110 needs to be adjusted, the first pin 324 is inserted out of the first rotating shaft 323, disengaging their rotation and releasing the control of the drive motor 311 on the opening and closing of the cover 120. The second pin 335 is then inserted into the third rotating shaft 334, locking the third rotating shaft 334 and the connecting cylinder 332 together. Both rotate synchronously, and the drive motor 311 drives the second helical gear 312 to rotate. The second helical gear 312 drives the third helical gear 325 to rotate through the helical gear meshing principle. The third helical gear 325 drives the hollow shaft 321 to rotate, and the fourth helical gear 326 rotates with the hollow shaft 321. The fourth helical gear 326, through... The helical gear meshing principle drives the sixth helical gear 336 to rotate, which in turn drives the second rotating shaft 331 and the connecting cylinder 332 to rotate. The third rotating shaft 334 rotates with the connecting cylinder 332, and the third rotating shaft 334 drives the seventh helical gear 337 to rotate. The seventh helical gear 337 drives the first helical gear 215 to rotate through the helical gear meshing principle. The first helical gear 215 drives the first screw 214 to rotate. Through the threaded transmission between the first screw 214 and the fixed block 213, the height of the first screw 214 changes, and the position of the movable cylinder 212 slides along the fixed cylinder 211. The movable cylinder 212 drives the height of the incubator 110 to change, making it easier for medical staff to adjust the incubator 110 to a position that is easy to operate. When the cover 120 needs to be opened and closed, the second pin 335 is pulled out from the third rotating shaft 334, releasing the pin lock between the third rotating shaft 334 and the connecting cylinder 332. Their rotation is disengaged. At this time, the third rotating shaft 334 does not rotate with the connecting cylinder 332, thereby releasing the drive of the driving member 310 on the adjusting leg 210. The first pin 324 is then inserted into the first rotating shaft 323. At this time, the hollow shaft 321 and the first rotating shaft 323 are pin locked, and they can rotate synchronously. 321 drives the first rotating shaft 323, which in turn drives the fifth helical gear 327. The fifth helical gear 327, through the helical gear meshing principle, drives the linkage box 410. The linkage box 410 drives the lower end of the first L-shaped connecting rod 420 to descend or rise, and the upper end of the first L-shaped connecting rod 420 drives the cover 120 to flip open and close. Conversely, if the first pin 324 is inserted out of the first rotating shaft 323, the rotation of the two is disengaged, releasing the control of the drive motor 311 on the opening and closing of the cover 120. The height adjustment of the incubator 110 and the opening and closing of the cover 120 can both be controlled by a single motor with simple human assistance, allowing the incubator to switch between height adjustment and cover opening / closing, thus saving circuitry and drive components.

[0070] When the fifth helical tooth 327 rotates, it drives the eighth helical tooth 416 at the top of the second screw 412 to rotate through the helical tooth meshing principle. The second screw 412 rotates accordingly. The eighth helical tooth 416 at the top of the second screw 412 drives the eighth helical tooth 416 at the top of the third screw 414 to rotate through the linkage shaft part 417. The third screw 414 rotates accordingly. The second screw 412 drives the first slider 413 to slide along the outer wall of the linkage box 411 through the thread transmission principle. The third screw 414 drives the second slider 415 to slide along the outer wall of the linkage box 411 through the thread transmission principle. The first slider 413 and the second slider 415 move in opposite directions. 13. Pulling the first L-shaped connecting rod 420, when the first L-shaped connecting rod 420 pulls the cover 120 open, the second slider 415 pushes the second L-shaped connecting rod 440, and the second L-shaped connecting rod 440 pushes the support seat 430 to flip open until the support seat 430 supports the cover 120 and stops. The support seat 430 provides a support surface for the cover 120, increasing the support area of ​​the cover 120, thereby effectively reducing the problem that the cover or its hinges are easily damaged when the cover is subjected to pressure unexpectedly. In addition, the support structure also uses a drive motor to provide power, thereby enabling the drive motor to achieve the effect of multiple actions in one machine, namely driving the adjusting leg, driving the cover and driving the support structure.

[0071] When the first pin part 324 is performing the pinning operation, the folded pin 3355 is flipped over and inserted into the connecting cylinder 332. The compression spring 3354 presses down on the pressure plate 3353, and the pressure plate 3353 drives the movable frame 3352 to tighten. The folded pin 3355 presses down on the third rotating shaft 334. As the connecting cylinder 332 rotates, when the insertion hole on the third rotating shaft 334 and the folded pin 3355 are aligned, the folded pin 3355 automatically inserts into the third rotating shaft 334 under the elastic force of the compression spring 3354, completing the pin connection and locking between the third rotating shaft 334 and the connecting cylinder 332. This reduces the need for manual alignment and facilitates quick pin connection. After pulling out the first pin part 324 in the reverse order, the folded pin 3355 is folded up, and the connecting cylinder 332 blocks the folded pin 3355. At this time, it is not necessary to remove the folded pin 3355, reducing the possibility of the folded pin 3355 being lost.
