[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be described below in conjunction with the drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0049] At present, with the continuous development of medical technology and the growing demand for medical services, the automation and intelligence of medical equipment has become an important means to improve the quality and efficiency of medical services. In the medical process, cotton swabs are common medical supplies with huge demand. However, the traditional cotton swab unpacking method requires medical staff to do it manually, which is not only labor-intensive and inefficient, but also has certain health risks.

[0050] In order to improve the above problems, an embodiment of the present invention provides an automatic packaging unpacking device and a control method, which are described in detail below.

[0051] This embodiment provides an automatic packaging device. Figure 1 The automatic packaging device shown in the figure comprises: a controller 11 and a conveying device 12, a bag cutting device 13 and a pushing device 14 connected to the controller in communication; Figure 1 As shown, the bag cutting device 13 is located at the first end of the conveying device 12, and the first end of the pushing device 14 is provided with an outlet.

[0052] The outdoor communication mode between the controller 11 and the conveying device 12, the bag cutting device 13 and the pushing device 14 can be wired communication or wireless communication.

[0053] The controller 11 is used to control the conveying device 12 to transfer the unpacking object to be unpacked at the input port to the pushing station when receiving the unpacking start signal; the conveying starting point of the conveying device 12 is the input port, and the conveying end point is the position of the pushing device 14;

[0054] The bag cutting device 13 includes a blade; the controller 11 is also used to drive the blade to cut off the first end package seal of the packaged object to be unpacked passing through the bag cutting device 13 during the transmission process of the packaged object to be unpacked, so that the first end of the packaged object to be unpacked is an open end;

[0055] The blade of the bag cutting device 13 is arranged at the first end of the conveying device. When the packaged object to be unpacked is transferred from the input port to the pushing station, it will pass through the bag cutting station. The setting position of the blade can be set according to the size of the packaged object to be unpacked, so that the package seal at the first end of the packaged object to be unpacked passes through the cutting area of ​​the blade, so as to cut off the package seal at the first end of the packaged object to be unpacked, so that the target object in the package can be easily pushed out, reducing the pushing resistance;

[0056] The first end of the pushing device 14 is provided with an outlet. The controller 11 is also used to control the pushing device 14 to push the target object in the package of the unpacked object to the outlet through the open end when the unpacked object with the package seal at the first end cut off arrives at the pushing station.

[0057] The above-mentioned outlet is arranged at the first end of the pushing device 14, in the same direction as the setting direction of the blade (such as, Figure 1 The middle bag cutting device 14 and the outlet are respectively arranged at the lower ends of the conveying device 12 and the pushing device 14 so as to push the target object in the package from the package opening direction to the outlet.

[0058] The objects to be unpacked may be a row of cotton swab bags with cotton swabs individually packaged therein, or a row of disinfection sticks or other medical supplies with individual packaging.

[0059] The above-mentioned automatic unpacking equipment provided in this embodiment can automatically peel out packaged medical supplies one by one and automatically push the peeled medical supplies to the outlet by integrating a conveying device, a bag cutting device and a pushing device in the automatic unpacking equipment, thereby saving unpacking time, improving unpacking efficiency, and reducing the risk of contaminating medical supplies during manual unpacking.

[0060] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a first detection device and an alarm device connected to the controller in communication; the first detection device is arranged at the input port;

[0061] The controller is also used to determine whether there is an object to be unpacked at the input port according to the feedback signal of the first detection device. When there is no object to be unpacked at the input port, the controller controls the alarm device to sound an alarm to prompt the replenishment of the object to be unpacked.

[0062] The above-mentioned first detection device can be a photoelectric switch. The transmitter and receiver of the photoelectric switch can be respectively arranged at the top and bottom of the input port. When there is an object to be unpacked at the input port, the light emitted by the transmitter will be blocked. The intensity of the light received by the photoelectric switch receiver can be used to determine whether there is an object to be unpacked at the input port.

[0063] The alarm device may be a buzzer. When the first detection device detects that the input port is insufficiently stocked, the alarm device sounds an alarm to prompt the staff to replenish the objects to be unpacked in time.

[0064] In one embodiment, the conveying device provided in this embodiment includes a first motor and a plurality of transmission components, and the first motor is electrically connected to the controller;

[0065] The controller is used for sending a rotation electric signal to the first motor when receiving the unpacking start signal, so that the first motor drives the transmission assembly to drive the unpacking object to move toward the pushing device.

[0066] The transmission assembly can be a conveyor belt or a plurality of rollers or other conveying parts. The motor drives the transmission assembly through a transmission mechanism such as a gear set to transfer the object to be unpacked to the pushing station.

[0067] The above-mentioned automatic unpacking device may be provided with a start button. When the user presses the start button, the controller receives the start unpacking signal input by the user, sends a rotation direction electrical signal and a pulse signal to the first motor to control the motor speed, and the first motor drives the transmission assembly through the transmission mechanism to move the object to be unpacked toward the pushing device.

[0068] In one embodiment, the blade provided in this embodiment is a rolling blade, and the bag cutting device further includes a second motor, and the second motor is electrically connected to the controller;

[0069] The controller is used for sending a rotation electric signal to the second motor when receiving the unpacking start signal, so that the second motor drives the roller to rotate, so as to cut off the first end packaging seal of the unpacked object passing through the bag cutting station.

[0070] The first motor and the second motor may be the same motor or different motors.

[0071] The above-mentioned roller is used to cut the packaging bag of the packaging object to be unpacked to ensure that the target object in the package can be peeled out smoothly. The roller is used as a cutting tool, and its power comes from the second motor. The second motor can be driven by a gear set to drive the roller to quickly cut the first end packaging seal of the packaging object to be unpacked.

[0072] When the packaged objects are being transported from the input port to the push station, the first-end package seals will pass through the cutting station where the roller is located, and will be automatically cut off when they reach the cutting station, saving bag cutting time and improving unpacking efficiency.

[0073] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a detection component electrically connected to the controller, the pushing device includes a third motor, a guide groove and a push block, and the third motor is electrically connected to the controller; the detection component is used to detect whether the object to be unpacked reaches the guide groove position;

[0074] The exit is located at the first end of the guide groove, and the initial position of the push block is located at the second end of the guide groove;

[0075] The controller is also used to determine whether the unpacked object reaches the guide groove according to the feedback signal of the detection component. When the unpacked object reaches the guide groove, the controller controls the third motor to rotate forward to drive the push block to move toward the first end of the guide groove.

[0076] The detection component can be a sensor such as a micro switch, which is arranged at the end of the conveying device or at the pushing station. When the object to be unpacked reaches the pushing station, an electrical signal can be fed back to the controller. The third motor can drive the push block to move along the direction of the guide groove through a transmission mechanism such as a screw assembly. When the third motor rotates forward, the push block moves from the second end of the guide groove to the direction of the first end outlet, pushes the target object in the package out of the package from the first end opening, and continues to push it to the outlet, waiting for the staff to take it.

[0077] In order to facilitate pushing out the target object, a guide groove can be set at the pushing station, and the first end of the guide groove can be connected to the outlet, so that the push block in the guide groove can smoothly push the target object in the package to be unpacked after the first end seal is cut off to the outlet.

[0078] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a proximity switch; the proximity switch is electrically connected to the controller;

[0079] The controller is also used to determine whether the push block reaches the preset position according to the feedback signal of the proximity switch, and when the push block reaches the preset position, determine that the target object reaches the exit, and control the third motor to stop rotating.

[0080] The proximity switch can be set at a preset position, which is the position of the push block when the push block pushes the target object to the exit. When the push block reaches the preset position, the proximity switch is activated. When the controller detects the activation of the proximity switch, it is determined that the push block has reached the preset position, that is, it is determined that the target object in the package has been pushed to the exit, and the controller sends a stop rotation signal to the third motor, that is, stops sending a pulse signal to the third motor.

[0081] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a second detection device; the second detection device is located at the initial position of the push block;

[0082] The controller is also used to control the third motor to reverse after the push block reaches a preset position and the third motor stops rotating, so as to drive the push block to move to an initial position, and to determine in real time whether the push block has returned to the initial position based on a feedback signal from the second detection device; when the push block reaches the initial position, the third motor is controlled to stop rotating.

[0083] When the push block reaches the preset position, the controller controls the third motor to stop rotating, and then sends a reverse signal to the third motor to drive the push block to move from the first end of the guide slot to the initial position of the second end to prepare for the next push.

[0084] A second detection device can be provided at the second end of the guide groove, and the second detection device can be an object detection sensor such as a photoelectric switch. The controller can determine whether the push block returns to the initial position based on the feedback signal of the second detection device. When the push block reaches the second end of the guide groove, the signal fed back to the controller by the second detection device changes. The controller determines that the push block has reached the second end of the guide groove, and controls the third motor to stop rotating, so that the push block remains at the initial position.

[0085] In one embodiment, the automatic packaging unpacking device provided in this embodiment further includes: a third detection device electrically connected to the controller; the third detection device is arranged at the warehouse outlet;

[0086] The controller is used to determine whether the target object at the warehouse opening has been taken away according to the feedback signal of the third detection device, and control the conveying device to stop operating when the target object has not been taken away. After the target object has been taken away, the controller controls the conveying device to transfer the next object to be unpacked to the pushing station.

[0087] The above-mentioned third detection device can be an object detection sensor such as a photoelectric switch. The controller can determine whether the target object at the outlet has been taken away based on the feedback signal of the third detection device. When the target object at the outlet has not been taken away, the first motor of the conveying device is controlled to stop running to stop the conveying device; when the target object at the outlet is taken away, the signal fed back to the controller by the third detection device changes, and the first motor of the conveying device is controlled to continue running to prepare for the next unpacking and pushing.

[0088] In one embodiment, the controller may be a programmable logic controller (PLC), and the motors may be stepper motors.

[0089] In one embodiment, the object to be unpacked is a cotton swab. Figure 2 The programmable logic controller wiring diagram shown in the figure is Figure 2 The figure shows the wiring diagram of each connection port of the PLC controller and each sensor and motor.

Figure 2 KA1 to KA6 are current relays to protect the motor and sensor circuits from overload and short circuit. The PLC controller is also electrically connected to the switch button of the device. When the button is pressed, the PLC controller receives a start-unpacking signal.

[0090] The above-mentioned automatic packaging unpacking equipment provided in this embodiment includes three modules: sensor perception system, PLC control system and execution system. The sensor perception system is responsible for real-time monitoring of the conveying, bag cutting and pushing out process of the cotton swab, and provides accurate feedback signals to the controller, including sensors such as photoelectric switches, proximity switches and micro switches. The PLC control system integrates the signal converter and PLC controller as the core, which is used to receive sensor signals, perform logical judgments, and output control instructions.

[0119] Before the machine is running, the operator neatly places a row of individually packaged cotton swab bags into the input port of the conveying device, turns on the power, presses the start button, and the machine starts to work automatically; the conveying device inside the machine will transfer the cotton swab bags to the bag cutting device one by one, and after cutting, they will continue to be transferred to the pushing device; the pushing device will push a single cotton swab to the exit port, waiting for the staff to take it. The machine is equipped with an automatic sensing system (the third detection device), which can detect the exit status of the cotton swab in real time. Once it senses that the cotton swab has been taken away, it will immediately prepare to push out the next cotton swab. In addition, the machine also has an inventory detection function (the first detection device). When the internal cotton swabs are exhausted, a prompt sound will be issued through the alarm device to remind the operator to replenish the cotton swabs in time.

[0120] Corresponding to the automatic packaging equipment provided in the above embodiment, see Figure 5-Figure 11 The embodiment of the present invention provides an automatic cotton swab unpacking machine, including a first driver 410 (i.e., the first motor and the second motor), a second driver 420 (i.e., the third motor), a conveying device 100, a bag cutting device 200, and a pushing device 300; the bag cutting device 200 and the pushing device 300 are arranged in sequence along the conveying direction of the conveying device 100, the conveying device 100 and the bag cutting device 200 are both connected to the first driver 410, and the conveying device 100 and the bag cutting device 200 operate synchronously; the pushing device 300 is connected to the second driver 420; the conveying device 100 is used to drive and convey the cotton swab bag, the bag cutting device 200 is used to cut the first end of the cotton swab bag, and the pushing device 100 is used to push the cotton swab out of the incision of the cotton swab bag. Among them, on the incoming side of the pushing device 300, there are cotton swabs in the cotton swab bags.

[0121] When in use, a cotton swab bag containing cotton swabs is placed at the input port of the conveying device 100, and the first driver 410 is controlled to start working, driving the conveying device 100 and the bag cutting device 200 to operate synchronously. The conveying device 100 can convey the cotton swab bag along the conveying direction. Under the conveying of the conveying device 100, the cotton swab bag will pass through the bag cutting device 200 and the pushing device 300 in sequence; when the cotton swab bag reaches the bag cutting device 200, the bag cutting device 200 can cut one end of the cotton swab bag to form an incision at one end of the cotton swab bag; when the cotton swab bag with the incision reaches the pushing device 300, the second driver 420 is controlled to drive the pushing device 300 to push the cotton swab in the cotton swab bag, so as to push the cotton swab out of the incision of the cotton swab bag, thereby realizing automatic unpacking of the cotton swab.

[0122] In the specific structure of the automatic cotton swab unpacking machine provided in this embodiment, a shell 600 can be set. The above-mentioned conveying device 100, bag cutting device 200 and pushing device 300 can all be installed in the shell 600. The shell 600 is provided with an input port 630, an output port and an outlet port 620. The input port 630 is opposite to the input end of the conveying device 100 and is used for placing the cotton swab bag; the output port is opposite to the output end of the conveying device 100 and is used for outputting discarded empty bags; the outlet port 420 is opposite to the pushing device 300 and is used for outputting the cotton swabs pushed out of the cotton swab bag.

[0123] like Figure 8 As shown, the automatic cotton swab unpacking machine provided in this embodiment also includes a first photoelectric switch 520 (i.e., the above-mentioned first detection device), a second photoelectric switch 550 (i.e., the above-mentioned second detection device), a third photoelectric switch 530 (i.e., the above-mentioned third detection device) and a proximity switch 540. The first photoelectric switch 520, the second photoelectric switch 550, the third photoelectric switch 530 and the proximity switch 540 can all be installed on the housing 600.

[0124] A transmission component may also be provided in the specific structure of the automatic cotton swab unpacking machine provided in the present embodiment. In the specific structure of the conveying device 100, a plurality of roller groups may be provided at intervals along the conveying direction. The roller groups may specifically include a plurality of pairs of driving wheels 110 and driven wheels 120 that cooperate with each other in rolling manner. The gaps between the driving wheels 110 and the driven wheels 120 allow the cotton swab bags to pass through them. The driving wheels 110 in the same group of roller pairs are coaxially arranged. The first driver 410 is connected to the driving wheels 110 through the transmission component, so that the first driver 410 can drive the driving wheels 110 to rotate synchronously through the transmission component. The rotation of the driving wheels 110 can convey the cotton swab bags forward. The presence of the driven wheels 120 makes the cotton swab bags less likely to slip, thereby improving the conveying reliability.

[0125] Generally, cotton swab bags are long and thin strips. Setting the conveying direction of the conveying device 100 to be perpendicular to the length direction of the cotton swabs is beneficial to improving the conveying efficiency of the cotton swab bags, and can also improve the compactness of the structure. The volume is small and can be set to a small desktop structure to ensure that the machine is small and light, does not take up too much space, and is easy to use in a medical environment. It is particularly suitable for conveying multiple cotton swab bags connected together without separating the cotton swab bags. The size of the whole machine can be 300mm×220mm×120mm (length×width×height). At this size, it can handle cotton swabs of various specifications with a length ranging from 100mm to 200mm.

[0126] In the specific structure of the conveying device 100, a first connecting shaft 130 and a plurality of second connecting shafts 140 are provided, and the driven wheel 120 is provided above the corresponding driving wheel 110 so as to support the driven wheel 120 with the driving wheel 110; the driven wheel 120 located at the incoming material side of the pushing device 300 is installed on the second connecting shaft 140, the first connecting shaft 130 is installed on the housing 600, and the second connecting shaft 130 is connected to the first connecting shaft 130 through the swinging member 150, wherein the first connecting shaft 130 and the swinging member 150 is rotatably connected, and the first connecting shaft 130 and the second connecting shaft 140 are parallel to the axis of the driving wheel 110. In this way, when the cotton swab in the cotton swab bag moves to between the driven wheel 120 and the driving wheel 110, the driven wheel 120 can be lifted up, so that the gap between the driving wheel 110 and the driven wheel 120 is enlarged, so that the cotton swab can pass through the gap between the driving wheel 110 and the driven wheel 120; and when the cotton swab in the cotton swab bag passes through, the driven wheel 120 can fall back to smoothly press the flat cotton swab bag to ensure the conveying effect.

[0127] A torsion spring can also be arranged between the first connecting shaft 130 and the second connecting shaft 140. When the cotton swab in the cotton swab bag moves between the driven wheel 120 and the driving wheel 110, the driven wheel 120 can be lifted up, and the torsion spring can produce adaptive deformation to adapt to the swing of the second connecting shaft 140. When the cotton swab in the cotton swab bag passes through, the torsion spring can drive the driven wheel 120 to reset, thereby increasing the force between the driven wheel 120 and the driving wheel 110 and improving the conveying stability.

[0128] The above-mentioned roller pair may include a first roller pair 160, which is located between the bag cutting device 200 and the pushing device 300; a micro switch 510 (i.e. the above-mentioned detection component) can be installed on the shell 600, and the micro switch 510 can be triggered when the driven wheel 120 in the first roller pair 160 is lifted by the cotton swab; the micro switch 510 and the second driver 420 are both communicatively connected to the controller, and when the micro switch 510 is triggered, the controller can control the second driver 420 to drive the pushing device 300 to push the cotton swab out of the incision of the cotton swab bag, thereby realizing automatic opening of the second driver 420 and improving the intelligence level.

[0129] The above-mentioned roller pair also includes a second roller pair 170 and a third roller pair 180. The second roller pair 170, the bag cutting device 200, the first roller pair 160, the pushing device 300 and the third roller pair 180 are arranged in sequence along the conveying direction. In this way, the second roller pair 170 and the first roller pair 160 can tighten the cotton swab bag between the two, so that the cotton swab bag corresponding to the bag cutting device 200 will be in a taut state, which is beneficial for the bag cutting device 200 to cut the cotton swab bag; similarly, the first roller pair 160 and the third roller pair 180 can tighten the cotton swab bag between the two, so that the cotton swab bag corresponding to the pushing device 300 will be in a taut state, which is beneficial for the pushing device 300 to smoothly push out the cotton swabs in the cotton swab bag.

[0130] In the specific structure of the bag cutting device 200, a roller cutter 210 and an auxiliary wheel 220 may also be provided, and the first driver 410 is connected to the roller cutter 210 through a transmission assembly, so that the roller cutter 210 is driven to rotate by the first driver 410; the auxiliary wheel 220 is rotatably mounted on the housing 600, and the roller cutter 210 and the auxiliary wheel 220 are rolled together, and the cotton swab bag passes through the gap between the auxiliary wheel 220 and the roller cutter 210, so that the roller cutter 210 can cooperate with the auxiliary wheel 220 to cut the cotton swab bag when rotating. It should be noted that the use of the combined structure of the roller cutter 210 and the auxiliary wheel 220 to cut the cotton swab bag can reduce the pulling force on the cotton swab bag during cutting, thereby reducing the impact of the cutting process on the overall transportation of the cotton swab bag, so that the cotton swab bag can be smoothly transported by the conveying device 100.

[0131] The bag cutting device 200 may specifically include a third connecting shaft 230 and an elastic member, the roller cutter 210 is coaxially fixedly connected to the third connecting shaft 230, an arc groove 610 is provided on the housing 600, and the third connecting shaft 230 is slidably matched with the arc groove 610, so that the third connecting shaft 230 can be moved along the arc groove 610 to adjust the position of the roller cutter 210, thereby adjusting the distance between the roller cutter 210 and the auxiliary wheel 220, increasing the distance, and facilitating the removal of the remaining cotton swabs in the machine. An elastic member may be connected between the housing 600 and the third connecting shaft 230, and the elastic force applied by the elastic member to the third connecting shaft 230 is set to be in the direction of the auxiliary wheel 220, so that, without the action of external force, the roller cutter 210 installed on the third connecting shaft 230 can be pressed against the auxiliary wheel 220, and the elastic member can also increase the pressure of the roller cutter 210 on the cotton swab bag to improve the cutting effect. Among them, the elastic member may be a spring 240.

[0132] Preferably, an annular groove may be provided on the wheel surface of the auxiliary wheel 220, and the blade of the rolling cutter 210 may be matched with the annular groove, so that the auxiliary wheel 220 may provide a stable supporting force for the cotton swab bag, thereby ensuring a smooth cutting process.

[0133] Furthermore, the cross-sectional shape of the annular groove may be set to be V-shaped, which may improve the supporting effect of the auxiliary wheel 220 on the cotton swab bag, thereby optimizing the cutting effect.

[0134] A gear set can be used as the transmission assembly, in which a driving gear 710, a first driven gear 720 and a second driven gear 730 can be provided, and the first driver 410 is connected to the driving gear 710, so that the first driver 410 drives the driving gear 710 to rotate, and the rotation of the driving gear 710 can drive each first driven gear 720 to rotate accordingly; the first driven gear 720 is provided in a one-to-one correspondence with the roller pair, and the first driven gear 720 is coaxially fixedly connected with the driving wheel 110 in the corresponding roller pair, so that the driving wheel 110 in each roller pair can rotate under the drive of the corresponding first driven gear 720, thereby realizing the driving of the conveying device 100. The second driven gear 730 is coaxially fixedly connected with the roller cutter 210, so that when the second driver 420 drives the driving gear 710 to rotate, the driving gear 710 can drive the second driven gear 730 to rotate synchronously, and then the second driven gear 730 can drive the roller cutter 210 to rotate, thereby realizing the cutting operation of the cotton swab bag. Specifically, the size of the first driven gear 720 can be adjusted according to the required linear speed of each roller pair to ensure the stability and accuracy of the cotton swab during the conveying process; the size of the second driven gear 730 can be adjusted according to the required rotation speed of the hob 210.

[0135] The bag cutting device 200 may further include an adjusting member 250, and the third connecting shaft 230 is rotationally matched with a portion of the adjusting member 250. If there is a first driven gear 720 meshing with the second driven gear 730, the first driven gear 720 may be rotationally matched with another portion of the adjusting member 250; if the driving gear 710 is directly meshing with the second driven gear 730, the driving gear 710 may be rotationally matched with another portion of the adjusting member 250. When it is necessary to adjust the distance between the roller 210 and the auxiliary wheel 220, the adjusting member 250 can be pulled to swing the adjusting member 250 around the axis of the corresponding first driven gear 720 or the axis of the driving gear 710, so that the third connecting shaft 230 slides along the arc groove 610, and at the same time, the second driven gear 730 can roll along the first driven gear 720 or the driving gear 710 meshing therewith, and with the support of the first driven gear 720 or the driving gear 710, the second driven gear 730 can roll smoothly, so that in the process of adjusting the position of the roller 210, the structural stability of the roller 210 can be guaranteed, and after releasing the adjusting member, the roller 210 can return to the cutting position by itself.

[0136] In addition, two limiters 800 can be set in the specific structure of the automatic cotton swab unpacking machine, and the two limiters 800 are respectively set on both sides of the conveying device 100, so as to use the two limiters 800 to limit the width of the conveying channel of the conveying device 100, wherein the conveying channel is used for the cotton swab bag to pass through; the limiter 800 is movably connected to the shell 600, and the limiter 800 can be fixed to multiple positions of the shell 600 along the width direction of the conveying channel, so that the width of the conveying channel can be adjusted by adjusting the position of the limiter 800 to adapt to cotton swab bags of different sizes, and the compatibility is stronger. In fact, the width direction of the conveying channel is consistent with the length direction of the cotton swab, and the spacing between the two limiters 800 can be adjusted to adapt to cotton swab bags of different lengths.

[0137] Specifically, a slideway and two groups of slot groups 640 can be provided on the shell 600, the guide of the slideway is set to be consistent with the width direction of the conveying channel, and the limit member 800 is slidably matched with the slideway so that the limit member 800 can slide along the slideway; the two groups of slot groups 640 are set in a one-to-one correspondence with the two limit members 800, and a plurality of slots arranged along the width direction of the conveying channel are set in each group of slot groups 640, and a hook is set on the limit member 800, and the hook is set to be able to elastically engage with any slot in the corresponding slot group 640, so that when the limit member 800 is pulled along the slideway, the hook on the limit member 800 can slide from one slot in the corresponding slot group 640 to another slot, and after the limit member 800 moves into place, the hook on the limit member 800 can cooperate with a slot in the corresponding slot group 640, and the slot can realize the positioning of the limit member 800, which is convenient for adjustment.
