[0058] Stacking is a relatively good way to reduce space occupation, however, simple stacking has the risk of falling, therefore, a stacking method which can realize stacking locking and easy unlocking and taking is needed.

[0059] In the related art, the stacking system needs to realize taking while manually keeping the unlocking state when taking the stacked pieces, which is inconvenient and has certain safety risks when the stacked pieces are heavy.

[0060] Please refer to FIG. 1-FIG. 43, in order to solve the problem of inconvenient operation when unlocking and taking the stacked pieces in the existing stacking system, the present application provides a stacking system 100 which can be used in storage and transportation fields.

[0061] It should be noted that in the following embodiments, the X direction, the Y direction and the Z direction correspond to the three spatial directions of the stacking system 100 respectively, but the X direction, the Y direction and the Z direction of the present application are not limited to the forms of expression in the embodiments.

[0062] Please continue to refer to FIG. 1-FIG. 11, the stacking system 100 provided by the present application comprises a first stacking device 10 and a second stacking device 20, the first stacking device 10 and the second stacking device 20 are stacked along the Z direction. The first stacking device 10 is provided with a first matching structure 30, and the second stacking device 20 is provided with a second matching structure 40. The first matching structure 30 and the second matching structure 40 have a locked state and an unlocked state, in the locked state, the first matching structure 30 and the second matching structure 40 are locked to connect the first stacking device 10 and the second stacking device 20. In the unlocked state, the first matching structure 30 and the second matching structure 40 can be unlocked. Wherein, the first matching structure 30 and the second matching structure 40 realize unlocking and / or locking through magnetic force.

[0063] It can be understood that, by setting the first matching structure 30 and the second matching structure 40, the present application can effectively connect the first stacking device 10 and the second stacking device 20 by the cooperation between the first matching structure 30 and the second matching structure 40, improve the stability of the stacking system 100 when stacking, can make full use of the storage space, and can ensure the transportation stability and the safety after stacking.

[0064] In an embodiment, the position of the first matching structure 30 and the second matching structure 40 in the locked state is defined as the locked position, and the position in the unlocked state is defined as the unlocked position, wherein the first matching structure 30 and the second matching structure 40 realize the positioning of the unlocked position and / or the locked position through magnetic force. The first matching structure 30 and the second matching structure 40 are positioned by magnetic force when in the unlocked position, so that the first stacking device 10 and the second stacking device 20 can be at least partially unlocked and separated. Wherein, when the first stacking device 10 and the second stacking device 20 are separated, the magnetic force between the first matching structure 30 and the second matching structure 40 decreases or disappears, at least one of the first matching structure 30 and the second matching structure 40 can be reset to the locked position. When the first stacking device 10 is stacked with the second stacking device 20 by gravity or external pressure, the first matching structure 30 and the second matching structure 40 are automatically locked. In this way, the cooperation of the first stacking device 10 and the second stacking device 20 as a whole is simpler, which can effectively improve the operation efficiency.

[0065] The number of the first stacking device 10 and the second stacking device 20 can be set to one or more, and can be set reasonably according to actual needs. Exemplarily, the first stacking device 10 is below and the second stacking device 20 is above in the present application, and the first stacking device 10 and the second stacking device 20 can be set to the same cuboid box structure as shown in FIG. 1 and FIG. 11, of course, other shapes such as polygonal prism or cylinder can also be set. In addition, the size of the first stacking device 10 and the second stacking device 20 can be set as shown in FIG. 7-FIG. 12. When the size of the first stacking device 10 and the second stacking device 20 is different, the length of the first stacking device 10 can be set to an integer multiple of the length of the second stacking device 20, so as to facilitate cooperation.

[0066] In order to further improve the reliability of the stacking connection between the first stacking device 10 and the second stacking device 20, in an embodiment, as shown in FIG. 2, FIG. 3, FIG. 9, FIG. 10 and FIG. 11, the first stacking device 10 is further provided with a third cooperation structure 50, which is arranged on the side of the first stacking device 10 opposite to the first cooperation structure 30 along the Y direction or the X direction. The second stacking device 20 is further provided with a fourth cooperation structure 60, which is arranged on the side of the second stacking device 20 opposite to the second cooperation structure 40 along the Y direction or the X direction. The third cooperation structure 50 and the fourth cooperation structure 60 are cooperatively connected, and when the third cooperation structure 50 and the fourth cooperation structure 60 are cooperated and the first cooperation structure 30 and the second cooperation structure 40 are cooperated, the movement of the first stacking device 10 and the second stacking device 20 in at least the Z direction is limited.

[0067] It can be understood that the cooperation between the third cooperation structure 50 and the fourth cooperation structure 60, in combination with the cooperation between the first cooperation structure 30 and the second cooperation structure 40, can ensure that the opposite ends of the first stacking device 10 and the second stacking device 20 can be connected, thereby limiting the movement of the first stacking device 10 and the second stacking device 20 in at least the Z direction.

[0068] Here, as shown in FIG. 3, the third cooperation structure 50 can adopt the same structure as the first cooperation structure 30, and the fourth cooperation structure 60 can adopt the same structure as the second cooperation structure 40. In this way, the cooperation between the third cooperation structure 50 and the fourth cooperation structure 60 is more firm, and can adapt to the first stacking device 10 and the second stacking device 20 with larger internal space and heavier weight.

[0069] Of course, the third cooperating structure 50 and the fourth cooperating structure 60 can also adopt different structures, for example, as shown in FIG. 10 and FIG. 11, one of the third cooperating structure 50 and the fourth cooperating structure 60 can be configured as a hook, and the other can be configured as a slot, and the hook is inserted into the slot to cooperate with the first cooperating structure 30 and the second cooperating structure 40 to limit the movement of the second stacking device 20 at least in the Z direction. In this way, the cooperation between the third cooperating structure 50 and the fourth cooperating structure 60 is simpler, which can effectively improve the efficiency of locking or unlocking between the first stacking device 10 and the second stacking device 20.

[0070] To further limit the movement of the first stacking device 10 relative to the second stacking device 20 in the X direction and the Y direction, in an embodiment, as shown in FIG. 8 and FIG. 9, one of the first stacking device 10 and the second stacking device 20 is protruded in the Z direction to form a limiting protrusion 22, and the other is recessed in the Z direction to form a limiting recess 101, and the limiting protrusion 22 is inserted into the limiting recess 101. In this way, the first stacking device 10 and the second stacking device 20 are more stable and reliable when stacked.

[0071] Specifically, the limiting protrusion 22 is arranged on the second stacking device 20, and the limiting recess 101 is arranged on the first stacking device 10.

[0072] The application specifically takes the structure of the third cooperating structure 50 and the first cooperating structure 30 as the same, and the structure of the fourth cooperating structure 60 and the second cooperating structure 40 as the same as an example for description. Among them, to realize the stacking effect of the stacking system 100, the second cooperating structure 40 and the fourth cooperating structure 60 can be arranged at the bottom of the second stacking device 20, and the first cooperating structure 30 and the third cooperating structure 50 can be arranged at the top of the second stacking device 20.

[0073] In an embodiment, the first cooperating structure 30 includes a first cooperating piece 31, the second cooperating structure 40 includes a second cooperating piece 41, and the first cooperating piece 31 and the second cooperating piece 41 are magnetically attracted or magnetically repelled. In this way, different magnetic cooperation modes can be used to realize the locking and unlocking between the first cooperating structure 30 and the second cooperating structure 40.

[0074] Further, in an embodiment, one of the first cooperating structure 30 and the second cooperating structure 40 is configured with a magnet, and the other is configured with a ferromagnetic body, that is, one of the first cooperating piece 31 and the second cooperating piece 41 is configured as a magnet, and the other is configured as a ferromagnetic body. In this way, the magnetic attraction of the first cooperating piece 31 and the second cooperating piece 41 can be realized.

[0075] It should be noted that the magnet is an object capable of generating a magnetic field by itself. The ferromagnetic object is an object with ferromagnetic properties and can be attracted by a magnetic field. The ferromagnetic object is usually made of iron, cobalt, nickel or alloy, or a high polymer material integrated with these components, such as an iron plastic part.

[0076] In another embodiment, the first fitting structure 30 and the second fitting structure 40 can also be provided with magnets, i.e., the first fitting part 31 and the second fitting part 41 are both provided with magnets. In this way, the magnetic attraction or magnetic repulsion of the first fitting part 31 and the second fitting part 41 can be achieved.

[0077] In other embodiments, the first fitting structure 30 and / or the second fitting structure 40 can also be provided with electromagnets, i.e., the first fitting part 31 and / or the second fitting part 41 are provided with electromagnets. By energizing the first fitting part 31 and / or the second fitting part 41 to generate magnetism, the fitting is more flexible. Here, the first fitting part 31 and the second fitting part 41 are both electromagnets as an example. Correspondingly, the stacking system 100 is provided with a corresponding electrical part 70.

[0078] For example, the first fitting part 31 and the second fitting part 41 can be energized to generate magnetic attraction. The first fitting structure 30 and the second fitting structure 40 are directly attracted by the strong magnetic action between the first fitting part 31 and the second fitting part 41, thereby achieving locking. When unlocking is required, the power is turned off to make the magnetic attraction disappear, thereby achieving unlocking.

[0079] In an embodiment, the stacking system 100 further comprises a control module 71. The control module 71 is in signal connection with the first fitting part 31 for controlling the magnetic state and the non-magnetic state of the first fitting part 31, and / or the control module 71 is in signal connection with the second fitting part 41 for controlling the magnetic state and the non-magnetic state of the second fitting part 41.

[0080] In this way, the magnetism generation of the first fitting part 31 and / or the second fitting part 41 is controlled.

[0081] Specifically, in the present embodiment, the control module 71 comprises a control switch 711. Of course, the control module 71 can also comprise an operation screen 712. In this way, both are conducive to manual operation, greatly improving the control convenience. The control switch 711 and the operation screen 712 can be reasonably arranged according to the space requirement.

[0082] For example, as shown in FIG. 5, the control switch 711 can be arranged on the first fitting structure 30 to control the magnetic state and the non-magnetic state of the first fitting part 31. Alternatively, as shown in FIG. 6, the operation screen 712 can be arranged on the first stacking device 10 to control the magnetic state and the non-magnetic state of the second fitting part 41.

[0083] Further, in an embodiment, as shown in FIG. 6, the stacking system 100 further comprises a wireless communication module 72 and a remote operation module 73, the wireless communication module 72 is installed on the first stacking device 10 and / or the second stacking device 20, and the wireless communication module 72 is signal connected with the control module 71 and the remote operation module 73 respectively. In this way, the switching between the locking state and the unlocking state of the stacking system 100 can be realized through electronic remote control, further improving the convenience.

[0084] Specifically, the wireless communication module 72 can be configured as wireless WiFi, Bluetooth, cellular network, satellite communication, NFC, mobile communication technology or long-distance wireless broadcast, etc., which are not listed one by one here.

[0085] In an embodiment, as shown in FIG. 6, the stacking system 100 further comprises a display module 74, which is used to indicate whether the stacking system 100 is in the locking state or the unlocking state. In this way, the locking and unlocking states of the stacking system 100 are more intuitive, so as to reduce the probability of operation failure and prevent the first stacking device 10 and the second stacking device 20 from being damaged.

[0086] Exemplarily, the display module 74 can be set as an indicator light, wherein red light can be used to indicate that the stacking system 100 is in the locking state, and green light can be used to indicate that the stacking system 100 is in the unlocking state. Of course, the light of the indicator light can also be set as other colors as long as it can play the same indicating role.

[0087] Herein, the first kind of embodiment of the cooperation between the first cooperation structure 30 and the second cooperation structure 40 is introduced:

[0088] Please refer to FIG. 3 and FIG. 4, in an embodiment, the first cooperation structure 30 further comprises a first movable piece 32, which is movably connected to the first stacking device 10. The first cooperation piece 31 is installed on the first movable piece 32. That is, in this embodiment, the first cooperation piece 31 can be moved by the first movable piece 32, so as to realize the locking and unlocking between the first cooperation structure 30 and the second cooperation structure 40.

[0089] To further improve the convenience, in an embodiment, as shown in FIG. 4, the first matching structure 30 further comprises a first elastic member 33, which is respectively connected to the first movable member 32 and the first stacking device 10 to apply force to the first movable member 32. The elastic force of the first elastic member 33 can cooperate with the magnetic force of the first matching member 31 and the second matching member 41 and the external applied force, etc., so as to realize the locking or unlocking of the stacking device. For example, during the stacking process, when the second stacking device 20 is stacked on the first stacking device 10, it is only necessary to directly carry and place the second stacking device 20 on the first stacking device 10, at which time the second stacking device 20 can automatically form a locked state by relying on the dead weight, which reduces the complexity of the locking operation and effectively improves the working efficiency and the convenience of the stacking positioning. The present application is specifically described by setting the structure with the first elastic member 33, wherein if the first elastic member 33 is not set, the movement of the first movable member 32 can also be directly realized by a manual mode.

[0090] Further, in an embodiment, as shown in FIG. 5 and FIG. 43, the first movable member 32 comprises a base 321 and a first clamping portion 322 provided on the base 321, and the base 321 is movably connected to the first stacking device 10. The second matching structure 40 comprises a second clamping portion 42 provided on the second stacking device 20, and the first clamping portion 322 can be inserted into the second clamping portion 42 and clamped and matched with the second clamping portion 42 to form a locked state. In this way, the matching of the first clamping portion 322 and the second clamping portion 42 is simple and can ensure the clamping effect, so as to realize the stacking limiting between the first stacking device 10 and the second stacking device 20.

[0091] Specifically, the first clamping portion 322 can be provided as a clamping plate, and a clamping groove can be correspondingly provided on the second clamping portion 42. It can be understood that the clamping plate and the clamping groove can be one-to-one correspondingly provided, or one clamping groove can be matched and clamped with multiple clamping plates. Here, the clamping groove can be directly slotted on the second clamping portion 42, or the second clamping portion 42 can be provided as a clamping hook structure, etc., so as to form the clamping groove by using the space of the bending part of the clamping hook.

[0092] Among them, the position and clamping direction of the first clamping portion 322 and the second clamping portion 42 can be reasonably set according to the moving direction of the first movable member 32, which will be described in detail below. It should be noted that the clamping direction of the first matching structure 30 and the second matching structure 40 can be set to be opposite to the clamping direction of the third matching structure 50 and the fourth matching structure 60, so as to facilitate preventing the clamping failure.

[0093] Further, as shown in FIG. 4, the first stacking device 10 is provided with a movable slot 102, and the base 321 is movably arranged in the movable slot 102, wherein the two opposite side walls of the movable slot 102 are provided with second limiting portions 1021. Correspondingly, the first movable piece 32 further comprises first limiting portions 326 connected to the two opposite side walls of the base 321, and the first limiting portions 326 can cooperate with the second limiting portions 1021 to limit the moving or rotating range of the first movable piece 32, so as to prevent the first movable piece 32 from being separated from the movable slot 102.

[0094] Specifically, the second limiting portions 1021 can be configured as protruding structures arranged on the side walls of the movable slot 102, and the first limiting portions 326 can be configured as elastic inverted clamping structures, so as to facilitate the installation of the first movable piece 32.

[0095] In order to facilitate the automatic movement of the first movable piece 32 under the weight of the second stacking device 20 when the first stacking device 10 and the second stacking device 20 are stacked, in an embodiment, as shown in FIG. 43, the first clamping portion 322 is provided with a first guide inclined surface 3221 arranged at one end of the first clamping portion 322 close to the second clamping portion 42.

[0096] Further, in an embodiment, as shown in FIG. 20, the second clamping portion 42 is provided with a second guide inclined surface 421 arranged at one end of the second clamping portion 42 close to the first clamping portion 322. In this way, when the second stacking device 20 is placed on the first stacking device 10, the cooperation between the first clamping portion 322 and the second clamping portion 42 is more smooth, so as to realize the quick locking between the first stacking device 10 and the second stacking device 20.

[0097] In order to further improve the reliability of clamping, in an embodiment, the number of the first clamping portions 322 is two, and the two first clamping portions 322 are arranged at intervals. Of course, the number of the first clamping portions 322 can also be one or more, which can be reasonably arranged according to actual needs.

[0098] In an embodiment, as shown in FIG. 43, the first movable piece 32 further comprises a first pushing portion 323 connected to the base 321, and the first pushing portion 323 is used to provide a force application position to slide or rotate the first movable piece 32. In this way, it is convenient for the user to pull or push the first movable piece 32.

[0099] Specifically, the first pushing portion 323 can be arranged as any one of a protrusion, a groove or knurling.

[0100] Further, in an embodiment, two or three of the base 321, the first clamping portion 322 and the first pushing portion 323 are arranged as an integrally formed structure, so as to facilitate processing and improve structural strength.

[0101] Please refer to FIG. 12-23, in the embodiment, the second cooperating member 41 is installed on the second stacking device 20, and the first cooperating member 31 and the second cooperating member 41 are magnetically attracted. That is, the position between the second cooperating member 41 and the second stacking device 20 in the embodiment remains basically unchanged, so the embodiment needs to use external force to move the first movable member 32 to achieve unlocking.

[0102] Further, as shown in FIG. 12-23, the first movable member 32 is slidingly connected to the first stacking device 10 along the Y direction. The first cooperating member 31 and the second cooperating member 41 are magnetically attracted along the Z direction. Here, the first cooperating member 31 and the second cooperating member 41 can be magnetically attracted in the locked state, or can be magnetically attracted in the unlocked state.

[0103] When the first cooperating member 31 and the second cooperating member 41 are magnetically attracted in the locked state, in the locked state, the first cooperating member 31 and the second cooperating member 41 can position the first cooperating structure 30 and the second cooperating structure 40 under the action of magnetic attraction. At this time, the first elastic member 33 generates and maintains deformation under the action of magnetic attraction, and the first elastic member 33 has a tendency to move the first clamping part 322 away from the second clamping part 42. When unlocking is needed, the first movable member 32 is moved by external force, so that the first cooperating member 31 and the second cooperating member 41 are misaligned, and the first elastic member 33 can automatically move the first movable member 32, which is more time-saving and labor-saving. Of course, the electromagnetic iron can also be used to make the magnetic force of the first cooperating member 31 or the second cooperating member 41 disappear, and the first movable member 32 moves to achieve automatic unlocking.

[0104] When the first cooperating part 31 and the second cooperating part 41 are in the magnetic attraction cooperation in the unlocking state, in the locking state, the first cooperating part 31 and the second cooperating part 41 are misaligned, and there is not enough magnetic attraction force between the first cooperating part 31 and the second cooperating part 41, so that the first elastic part 33 can apply force to the first movable part 32 to insert the first clamping part 322 into the second clamping part 42, thereby realizing clamping. When unlocking is needed, the first movable part 32 can be moved to a certain position under the action of an external force, thereby realizing the attraction effect between the first cooperating part 31 and the second cooperating part 41 at the corresponding position. At this time, the first elastic part 33 is deformed and maintained under the action of the magnetic attraction force, and the first elastic part 33 has a tendency to move the first clamping part 322 towards the second clamping part 42. At the same time, the first cooperating part 31 and the second cooperating part 41 can position the first cooperating structure 30 and the second cooperating structure 40 under the action of the magnetic attraction force, prevent the first movable part 32 from moving back under the action of the elastic force of the first elastic part 33, and make the first stacking device 10 and the second stacking device 20 in the non-locking state. Therefore, in the unlocking state, the first movable part 32 does not need to be controlled, and the second stacking part can be directly taken to realize stacking and disassembly, which is simple to operate. After disassembly is completed, the first cooperating part 31 and the second cooperating part 41 lose the magnetic attraction force due to the too far distance, and the first movable part 32 can automatically reset under the action of the elastic force of the first elastic part 33, and the overall operation is simpler.

[0105] Specifically, the first movable part 32 can slide along the Y direction towards the direction close to or away from the center of the first stacking device 10, thereby realizing unlocking of the first clamping part 322 and the second clamping part 42.

[0106] For the convenience of description, the present application only takes the magnetic attraction cooperation of the first cooperating part 31 and the second cooperating part 41 in the unlocking state as an example to illustrate.

[0107] When the first movable part 32 moves the first clamping part 322 away from the center of the first stacking device 10 under the action of an external force to release the clamping of the first clamping part 322 and the second clamping part 42 and form the unlocking state, that is, when the first movable part 32 is pulled outwards under the action of an external force, at this time, the clamping direction of the first clamping part 322 and the second clamping part 42 needs to be set as the Y direction towards the center of the first stacking device 10. Based on this, as shown in FIGS. 12 and 13, one end of the first clamping part 322 can be connected to the base 321, and the other end can extend towards the center of the first stacking device 10, thereby realizing the clamping requirement. It can be understood that the position of the second clamping part 42 corresponds to the first clamping part 322, which will not be described here.

[0108] Specifically, in the embodiment, the first clamping portion 322 is arranged on the side of the first fitting member 31 away from the center of the first stacking device 10, and the first clamping portion 322 extends from the side of the base 321 away from the center of the first stacking device 10 towards the center of the first stacking device 10. Since in the unlocked state, the first fitting member 31 and the second fitting member 41 are in the magnetic attraction fitting state, at this time, the first elastic member 33 is in the compressed state, and the first elastic member 33 is kept in the compressed state due to the magnetic attraction force.

[0109] Similarly, in another embodiment, when the first movable member 32 drives the first clamping portion 322 to move towards the center of the first stacking device 10 under the action of an external force to release the clamping of the first clamping portion 322 and the second clamping portion 42, and form an unlocked state, that is, when the first movable member 32 is pushed inwards by an external force to slide, at this time, the clamping direction of the first clamping portion 322 and the second clamping portion 42 needs to be arranged along the Y direction away from the center of the first stacking device 10. Based on this, as shown in FIGS. 14 and 15, the clamping requirement can be achieved by connecting one end of the first clamping portion 322 to the base 321 and extending the other end away from the center of the first stacking device 10.

[0110] Specifically, in the embodiment, the first clamping portion 322 is arranged on the side of the first fitting member 31 away from the center of the first stacking device 10, and the first clamping portion 322 extends from the side of the base 321 away from the center of the first stacking device 10 towards the center of the first stacking device 10. Since in the unlocked state, the first fitting member 31 and the second fitting member 41 are in the magnetic attraction fitting state, at this time, the first elastic member 33 is in the compressed state, and the first elastic member 33 is kept in the compressed state due to the magnetic attraction force. In this embodiment, the unlocking is achieved by pulling the first movable member 32.

[0111] In an embodiment, as shown in FIGS. 12-15, the base 321 is provided with an assembly groove 3201, and the first fitting member 31 is accommodated in the assembly groove 3201. In this way, the installation of the first fitting member 31 on the first movable member 32 can be achieved. The assembly groove 3201 can be arranged in the middle of the base 321 or symmetrically arranged. Of course, the assembly groove 3201 can also be arranged on the first clamping portion 322, and one or more assembly grooves 3201 can be arranged.

[0112] In another embodiment, as shown in FIGS. 16-19, the first movable member 32 further comprises a positioning block 324, the base 321 is provided with an assembly groove 3201, the positioning block 324 is installed in the assembly groove 3201 and movably connected with the base 321, and at least part of the positioning block 324 can protrude out of the assembly groove 3201. The at least part of the positioning block 324 forms the first fitting member 31, or the first fitting member 31 is installed on the positioning block 324. In this way, the attraction of the first fitting member 31 and the second fitting member 41 in the unlocked state can be achieved.

[0113] Wherein, the movement mode of the positioning block 324 in the assembly groove 3201 can be as shown in FIG. 16 and FIG. 17, one end of the positioning block 324 is rotationally connected with the base 321, at this time, the positioning block 324 is in line contact or surface contact with the second cooperating part 41. Or, as shown in FIG. 18 and FIG. 19, the positioning block 324 is movably guided with the inner wall of the assembly groove 3201, at this time, the positioning block 324 is in surface contact with the second cooperating part 41, thereby effectively ensuring the contact area and improving the reliability of magnetic attraction. In this way, the movement of the positioning block 324 in the Z direction can be realized, thereby meeting the positioning of the first cooperating part 31 and the second cooperating part 41.

[0114] Further, as shown in FIG. 16-FIG. 19, the second cooperating structure 40 further comprises a stop portion 43 provided on the second stacking device 20, the stop portion 43 can be arranged close to the second cooperating part 41. Wherein, when the first cooperating part 31 and the second cooperating part 41 are magnetically attracted, the positioning block 324 is at least partially stopped by the stop portion 43, so that the movement of the first movable part 32 is limited and positioned. In this way, the movement of the first movable part 32 driven by the first elastic part 33 can be prevented, so that the positioning effect is more reliable.

[0115] In an embodiment, as shown in FIG. 43, the first cooperating structure 30 further comprises a gear 34, a transmission plate 35 and a third rotating shaft 36, the first cooperating part 31, the gear 34, the transmission plate 35 and the third rotating shaft 36 are all installed in the base 321. The first cooperating part 31 is connected to the circumferential side of the third rotating shaft 36 and can rotate around the axis of the third rotating shaft 36, one end of the third rotating shaft 36 away from the first cooperating part 31 is connected to the gear 34. One end of the transmission plate 35 is in transmission connection with the gear 34, and the other end at least partially protrudes out of the outer surface of the base 321. In the locked state, the first cooperating part 31 and the second cooperating part 41 are magnetically attracted. When unlocking is needed, the transmission plate 35 can be moved under the action of external force and drive the gear 34, the third rotating shaft 36 and the first cooperating part 31 to rotate, so that the first cooperating part 31 rotates away from the second cooperating part 41. For example, the first cooperating part 31 can be rotated by 90° or 180°, etc., so that there is no magnetic attraction between the first cooperating part 31 and the second cooperating part 41, or the magnetic attraction is reduced to a certain extent, thereby avoiding affecting the movement of each other.

[0116] That is, in the unlocking process of the present embodiment, the gear 34 is used to drive the first cooperating part 31 to rotate, so that the magnetic attraction between the first cooperating part 31 and the second cooperating part 41 is weakened, so as to release the clamping between the first cooperating structure 30 and the second cooperating structure 40.

[0117] Further, in the locked state, the first elastic member 33 is deformed to make the first elastic member 33 have a tendency to drive the first clamping portion 322 to move away from the second clamping portion 42. In this way, when the magnetic force between the first cooperating member 31 and the second cooperating member 41 is smaller than the elastic force of the first elastic member 33, the base 321 can automatically pop out, thereby releasing the clamping and achieving the unlocking of the first cooperating structure 30 and the second cooperating structure 40. Of course, the first elastic member 33 can not be provided, and the unlocking can be achieved by manually pulling. In addition, according to actual needs, the second cooperating structure 40 can also adopt a gear 34 transmission mode similar to the first cooperating structure 30 to achieve the rotation of the second cooperating member 41.

[0118] Here, a second embodiment of the cooperation between the first cooperating structure 30 and the second cooperating structure 40 is introduced:

[0119] The basic structure and concept of the embodiment are basically the same as those of the first embodiment, and the same parts will not be described again. The difference is that, in the embodiment, as shown in FIGS. 20-23, the first movable member 32 is provided with a first rotating shaft 325, and the first movable member 32 is rotatably connected to the first stacking device 10 through the first rotating shaft 325. That is, the first movable member 32 of the embodiment is rotatably connected, so that the movement of the first movable member 32 relative to the first stacking device 10 is relatively simple and fast.

[0120] Further, the first elastic member 33 is a torsion spring, and the first elastic member 33 is sleeved on the outer periphery of the first rotating shaft 325 and abuts against the first movable member 32 and the first stacking device 10 respectively to apply force to the first movable member 32. In this way, when the first movable member 32 rotates under the action of an external force, the torsion spring is subjected to an acting force and deforms, and when the first movable member 32 rotates to a certain position, the first cooperating member 31 and the second cooperating member 41 are magnetically attracted and positioned, and when the second stacking device 20 and the first stacking device 10 are disassembled, the magnetic attraction force maintaining the deformation of the torsion spring disappears, and the torsion spring can drive the first movable member 32 to automatically reset.

[0121] Similarly, in the embodiment, the first movable member 32 also has two rotating directions, i.e., the first movable member 32 can rotate towards the center of the first stacking device 10 or away from the center of the first stacking device 10.

[0122] When the first movable part 32 drives the first clamping part 322 to move towards the center of the first stacking device 10 under the action of an external force to release the clamping of the first clamping part 322 and the second clamping part 42 and form an unlocked state, that is, when the first movable part 32 is turned upwards by the external force, at this time, the clamping direction of the first clamping part 322 and the second clamping part 42 needs to be set to be substantially along the Y direction away from the center of the first stacking device 10. Based on this, as shown in FIGS. 20 and 21, the clamping requirement can be achieved by connecting one end of the first clamping part 322 to the base 321 and extending the other end away from the center of the first stacking device 10.

[0123] Specifically, in the embodiment, the first clamping part 322 can be arranged on the side of the first cooperating part 31 away from the center of the first stacking device 10, and the first clamping part 322 extends from the side of the base 321 away from the center of the first stacking device 10 towards the center of the first stacking device 10.

[0124] Similarly, in another embodiment, when the first movable part 32 drives the first clamping part 322 to move away from the center of the first stacking device 10 under the action of an external force to release the clamping of the first clamping part 322 and the second clamping part 42 and form an unlocked state, that is, when the first movable part 32 is turned downwards by the external force, at this time, the clamping direction of the first clamping part 322 and the second clamping part 42 needs to be set to be substantially along the Y direction towards the center of the first stacking device 10. Based on this, as shown in FIGS. 22 and 23, the clamping requirement can be achieved by connecting one end of the first clamping part 322 to the base 321 and extending the other end towards the center of the first stacking device 10.

[0125] Specifically, in the embodiment, the first clamping part 322 can be arranged on the side of the first cooperating part 31 close to the center of the first stacking device 10, and the first clamping part 322 extends from the side of the base 321 close to the center of the first stacking device 10 towards the center of the first stacking device 10.

[0126] Since the first elastic part 33 in the embodiment adopts a torsion spring, the structure and installation direction of the torsion spring can be adjusted to realize that after the first cooperating part 31 and the second cooperating part 41 are separated, the first elastic part 33 loses the magnetic force limitation and drives the first movable part 32 to rotate and reset.

[0127] Herein, a third implementation of the cooperation of the first cooperating structure 30 and the second cooperating structure 40 is introduced:

[0128] The first movable member 32 in the embodiment has substantially the same structure as the first movable member 32 in the first embodiment, and the same parts will not be described again. The difference is that, in the embodiment, the first engaging member 31 is mounted on the first movable member 32, the second engaging structure 40 further comprises a second movable member 44, the second engaging member 41 is mounted on the second movable member 44, and the second movable member 44 is movably connected to the second stacking device 20. With the movement of the second movable member 44, the second engaging member 41 can be magnetically engaged with or disengaged from the first engaging member 31 to form a locked state or an unlocked state.

[0129] That is, in the embodiment, the magnetic engagement between the first engaging member 31 and the second engaging member 41 is achieved by the movement of the two movable members, and thus the locked state or the unlocked state of the stacking system 100 can be achieved.

[0130] Further, as shown in FIGS. 24-33, the first movable member 32 is slidably connected to the first stacking device 10, and the second movable member 44 is slidably connected to the second stacking device 20. The sliding direction of the first movable member 32 intersects the sliding direction of the second movable member 44. It can be understood that the sliding directions of the first movable member 32 and the second movable member 44 are arranged to intersect, which is more conducive to the engagement between the first engaging member 31 and the second engaging member 41. The sliding direction of the first movable member 32 can be perpendicular to the sliding direction of the second movable member 44, and the sliding is more simple.

[0131] Specifically, the sliding direction of the first movable member 32 is substantially parallel to the Y direction, and the sliding direction of the second movable member 44 is arranged at an angle with the sliding direction of the first movable member 32 to facilitate the sliding of the second movable member 44.

[0132] Here, the first engaging member 31 and the second engaging member 41 can be magnetically attracted or repelled in the locked state or the unlocked state.

[0133] When the first cooperating member 31 and the second cooperating member 41 are magnetically attracted to each other in the locked state, the first cooperating member 31 and the second cooperating member 41 can position the first cooperating structure 30 and the second cooperating structure 40 under the magnetic attraction. At this time, under the magnetic attraction, the first movable member 32 can drive the first clamping portion 322 to move to be clamped with the second clamping portion 42, and the first elastic member 33 is deformed and maintained under the magnetic attraction, and the first elastic member 33 has a tendency to drive the first clamping portion 322 to move away from the second clamping portion 42. That is, the first movable member 32 overcomes the elastic force of the first elastic member 33 to realize the clamping of the first clamping portion 322 and the second clamping portion 42 by the magnetic attraction. When unlocking is needed, the second movable member 44 drives the second cooperating member 41 to move to be misaligned with the first cooperating member 31 under the external force, and the magnetic attraction between the two is gradually weakened. At this time, the first movable member 32 can be automatically reset under the elastic force of the first elastic member 33 to release the clamping of the first clamping portion 322 and the second clamping portion 42.

[0134] It can be understood that, since the first cooperating member 31 and the second cooperating member 41 are magnetically attracted to each other, when the second cooperating member 41 moves away from the first cooperating member 31, the magnetic attraction is weakened, and the first movable member 32 can automatically slide and position under the elastic force of the first elastic member 33 to form an unlocked state, so that the first movable member 32 does not need to be operated by an external force, and the unlocking process is simpler.

[0135] Further, the first elastic member 33 is deformed in the locked state due to the magnetic force, and the deformation can be a compression deformation or a stretching deformation. Taking the compression deformation as an example, the first movable member 32 can move towards or away from the center of the first stacking device 10 by changing the connection end of the first elastic member 33 with the first stacking device 10.

[0136] For example, if the first movable member 32 is to move towards the center of the first stacking device 10, one end of the first elastic member 33 away from the center of the first stacking device 10 is connected with the first stacking device 10, and the other end of the first elastic member 33 is connected with the first movable member 32. At this time, the clamping direction of the first clamping portion 322 and the second clamping portion 42 is changed accordingly, specifically, one end of the first clamping portion 322 is connected with the base 321, and the other end extends away from the center of the first stacking device 10, that is, the first clamping portion 322 is clamped with the second clamping portion 42 away from the center of the first stacking device 10. In this way, when the first movable member 32 drives the first clamping portion 322 to slide under the external force, that is, to move towards the center of the first stacking device 10, the second cooperating member 41 can move away from the first cooperating member 31 to release the clamping of the first clamping portion 322 and the second clamping portion 42, and form an unlocked state.

[0137] The first clamping portion 322 can be arranged on the side of the first fitting member 31 away from the center of the first stacking device 10, and extend from the base 321 on the side away from the center of the first stacking device 10 towards the center of the first stacking device 10.

[0138] In addition, when the first movable member 32 is to be moved away from the center of the first stacking device 10, the first elastic member 33 can be connected to the first stacking device 10 on the side close to the center of the first stacking device 10, and the other end of the first elastic member 33 is connected to the first movable member 32. At this time, the clamping direction of the first clamping portion 322 and the second clamping portion 42 is changed, specifically, one end of the first clamping portion 322 is connected to the base 321, and the other end extends towards the center of the first stacking device 10, that is, the first clamping portion 322 clamps the second clamping portion 42 towards the center of the first stacking device 10. In this way, when the first movable member 32 is driven to slide by an external force, that is, when the first movable member 32 is moved away from the center of the first stacking device 10, the second fitting member 41 can be moved away from the first fitting member 31 to release the clamping of the first clamping portion 322 and the second clamping portion 42, and form an unlocked state.

[0139] The first clamping portion 322 can be arranged on the side of the first fitting member 31 away from the center of the first stacking device 10, and extend from the base 321 on the side away from the center of the first stacking device 10 towards the center of the first stacking device 10.

[0140] When the first elastic member 33 is in a tensile deformation in the locked state, only the end of the first stacking device 10 and the first movable member 32 connected to the first elastic member 33 needs to be changed, which will not be described in detail here.

[0141] When the first cooperating member 31 and the second cooperating member 41 are in the magnetic attraction cooperation in the unlocking state, in the locking state, the first cooperating member 31 and the second cooperating member 41 are misaligned, and there is not enough magnetic attraction force between the first cooperating member 31 and the second cooperating member 41, so the first elastic member 33 can exert force on the first movable member 32 to make the first clamping portion 322 inserted into the second clamping portion 42, and the clamping is achieved. When unlocking is needed, the second movable member 44 drives the second cooperating member 41 to move towards the first cooperating member 31 under the action of external force, and the magnetic attraction force between the two gradually increases. At this time, the magnetic attraction force overcomes the elastic force of the first elastic member 33 to drive the first movable member 32 to move, so as to release the clamping of the first clamping portion 322 and the second clamping portion 42. And in the unlocking state, the first cooperating member 31 and the second cooperating member 41 can position the first cooperating structure 30 and the second cooperating structure 40 under the action of magnetic attraction force. At this time, the first elastic member 33 generates and maintains deformation under the action of magnetic attraction force, and the first elastic member 33 has a tendency to drive the first clamping portion 322 to move towards the second clamping portion 42. It can be understood that since the first cooperating member 31 and the second cooperating member 41 are in magnetic attraction cooperation, when the second cooperating member 41 moves towards the first cooperating member 31, the magnetic attraction force increases, and the first movable member 32 can automatically slide and position under the action of magnetic force to form the unlocking state, so there is no need to operate the first movable member 32 by external force, and the unlocking process is simpler.

[0142] Further, in the magnetic attraction cooperation mode of the first cooperating member 31 and the second cooperating member 41 in the unlocking state, the connection mode of the first elastic member 33 and the setting position of the first clamping portion 322 are similar to those in the magnetic attraction cooperation mode in the locking state, and only the structure needs to be changed accordingly, which will not be described here.

[0143] When the first cooperating member 31 and the second cooperating member 41 are in magnetic repulsion cooperation in the locking state, in the locking state, the first cooperating member 31 and the second cooperating member 41 can position the first cooperating structure 30 and the second cooperating structure 40 under the action of magnetic repulsion force. At this time, under the action of magnetic repulsion force, the first movable member 32 can drive the first clamping portion 322 to move to be clamped with the second clamping portion 42, and the first elastic member 33 generates and maintains deformation under the action of magnetic repulsion force, and the first elastic member 33 has a tendency to drive the first clamping portion 322 to move away from the second clamping portion 42. That is, the first movable member 32 realizes the clamping of the first clamping portion 322 and the second clamping portion 42 by overcoming the elastic force through the magnetic repulsion force. When unlocking is needed, the second movable member 44 drives the second cooperating member 41 to move to be misaligned with the first cooperating member 31 under the action of external force, and the magnetic repulsion force between the two gradually decreases. At this time, the first movable member 32 can move back to the original position under the action of the elastic force of the first elastic member 33, so as to release the clamping of the first clamping portion 322 and the second clamping portion 42.

[0144] It can be understood that, since the first cooperating member 31 and the second cooperating member 41 are magnetically repulsive, when the second cooperating member 41 moves away from the first cooperating member 31, the magnetic repulsion force weakens, the first movable member 32 can automatically slide and position under the magnetic force to form an unlocked state, so that no external force is needed to operate the first movable member 32, and the unlocking process is simpler.

[0145] Further, in the manner that the first cooperating member 31 and the second cooperating member 41 are magnetically repulsive in the locked state, the connection manner of the first elastic member 33 and the setting position of the first clamping portion 322 are similar to those in the manner that the first cooperating member 31 and the second cooperating member 41 are magnetically attractive in the locked state, and only the structure needs to be changed accordingly, which will not be described here.

[0146] When the first cooperating member 31 and the second cooperating member 41 are magnetically repulsive in the unlocked state, in the locked state, the first cooperating member 31 and the second cooperating member 41 are misaligned, and there is not enough magnetic repulsion force between the first cooperating member 31 and the second cooperating member 41, so that the first elastic member 33 can apply force to the first movable member 32 to make the first clamping portion 322 inserted into the second clamping portion 42 to realize clamping. When unlocking is needed, the second movable member 44 drives the second cooperating member 41 to move towards the first cooperating member 31 under the action of external force, and the magnetic repulsion force between the first cooperating member 31 and the second cooperating member 41 gradually increases. At this time, the magnetic repulsion force overcomes the elastic force of the first elastic member 33 to drive the first movable member 32 to move, so as to release the clamping of the first clamping portion 322 and the second clamping portion 42. And in the unlocked state, the first cooperating member 31 and the second cooperating member 41 can position the first cooperating structure 30 and the second cooperating structure 40 under the action of the magnetic repulsion force. At this time, the first elastic member 33 generates and maintains deformation under the action of the magnetic repulsion force, and the first elastic member 33 has a tendency to drive the first clamping portion 322 to move towards the second clamping portion 42.

[0147] It can be understood that, since the first cooperating member 31 and the second cooperating member 41 are magnetically repulsive, when the second cooperating member 41 moves away from the first cooperating member 31, the magnetic repulsion force weakens, the first movable member 32 can automatically slide and position under the magnetic force to form an unlocked state, so that no external force is needed to operate the first movable member 32, and the unlocking process is simpler.

[0148] Further, in the manner that the first cooperating member 31 and the second cooperating member 41 are magnetically repulsive in the locked state, the connection manner of the first elastic member 33 and the setting position of the first clamping portion 322 are similar to those in the manner that the first cooperating member 31 and the second cooperating member 41 are magnetically attractive in the locked state, and only the structure needs to be changed accordingly, which will not be described here.

[0149] The above is the basic principle of the movement of the first cooperating structure 30 and the second cooperating structure 40 in the embodiment, based on which the embodiment also provides several embodiments based on the principle, as follows:

[0150] In an embodiment, as shown in FIGS. 24-31, the second stacking device 20 is further provided with an assembly hole 21, and the second movable element 44 is movably arranged in the assembly hole 21. In this embodiment, the second movable element 44 is slidable under the action of an external force to switch the first cooperating element 31 and the second cooperating element 41 between the cooperating state and the non-cooperating state.

[0151] For example, the assembly hole 21 and the second movable element 44 can both extend along the Z direction, and the arrangement of the second movable element 44 in the assembly hole 21 can improve the movement stability of the second movable element 44. In this embodiment, the second cooperating element 41 is connected to the end of the second movable element 44 that is close to the first movable element 32 along the Z direction.

[0152] Further, the sliding direction of the second movable element 44 is perpendicular to the sliding direction of the first movable element 32, and the second movable element 44 is slidable under the action of an external pulling or pushing force to switch the first cooperating element 31 and the second cooperating element 41 between the cooperating state and the non-cooperating state. In this way, the sliding of the second movable element 44 is simpler.

[0153] In this embodiment, the movement of the second movable element 44 can be linked with the action of moving the second stacking device 20, and when the operator holds the second stacking device 20 with his hand, the hand can contact the second movable element 44. In this embodiment, as shown in FIGS. 24-29, when the operator pulls the second movable element 44 with his hand before or during the exertion of the force, the second movable element 44 slides upward to be unlocked, so that the second stacking device 20 can be smoothly extracted. Of course, as shown in FIGS. 30 and 31, when the operator presses the second movable element 44 with his hand during the exertion of the force, the second movable element 44 slides downward to be unlocked, so that the second stacking device 20 can be smoothly extracted.

[0154] Please continue to refer to FIGS. 24-31, the side wall of the second movable element 44 is provided with a mounting hole 4401, and the second cooperating structure 40 further comprises a positioning assembly 45, which is arranged in the mounting hole 4401 and at least partially protrudes from the mounting hole 4401 to be connected with the inner wall of the assembly hole 21. In this way, the positioning of the second movable element 44 is facilitated, and the reliability of the second movable element 44 is improved.

[0155] Specifically, the positioning assembly 45 comprises a second elastic element 451 and a ball 452, one end of the ball 452 is connected to the second elastic element 451, and the other end at least partially protrudes from the mounting hole 4401 to be connected with the inner wall of the assembly hole 21. In this way, the positioning assembly 45 has a simple structure and is easy to process.

[0156] Further, as shown in FIGS. 24-31, the inner wall of the assembly hole 21 has a first matching position 211 and a second matching position 212, the first matching position 211 is located on the side of the second matching position 212 close to the first movable part 32. The first matching position 211 and the second matching position 212 correspond to the locked state and the unlocked state respectively, when the positioning assembly 45 is moved by the second movable part 44, the ball 452 on the positioning assembly 45 can cooperate with the first matching position 211 or the second matching position 212 respectively, thereby providing a tactile feedback to ensure that the second movable part 44 is moved to the position.

[0157] Exemplarily, when the second movable part 44 is unlocked by sliding upward along the Z direction under the action of external force, that is, when the second movable part 44 is pulled, the second movable part 44 can drive the positioning assembly 45 to move from the first matching position 211 to the second matching position 212. As shown in FIGS. 26 and 27, the first matching part 31 and the second matching part 41 are magnetically attracted and attracted in the locked state, after the second movable part 44 is pulled, the two are away from each other, the magnetic attraction force is weakened, the first movable part 32 is moved to realize unlocking under the action of the first elastic part 33. In FIGS. 28 and 29, the first matching part 31 and the second matching part 41 are magnetically repelled and misaligned in the locked state, after the second movable part 44 is pulled, the two are close to each other, the magnetic repulsion force is enhanced, thereby overcoming the elastic force of the first elastic part 33 to push the first movable part 32 to move to realize unlocking.

[0158] When the second movable part 44 is unlocked by sliding downward along the Z direction under the action of external force, that is, when the second movable part 44 is pressed, the second movable part 44 can drive the positioning assembly 45 to move from the second matching position 212 to the first matching position 211. As shown in FIGS. 30 and 31, the first matching part 31 and the second matching part 41 are magnetically repelled and misaligned in the locked state, after the second movable part 44 is pressed, the two are close to each other, the magnetic repulsion force is enhanced, thereby overcoming the elastic force of the first elastic part 33 to push the first movable part 32 to move to realize unlocking. Of course, the first matching part 31 and the second matching part 41 can also be magnetically attracted and attracted in the locked state, after the second movable part 44 is pressed, the two are away from each other, the magnetic attraction force is weakened, the first movable part 32 is moved to realize unlocking under the action of the first elastic part 33.

[0159] Specifically, the first matching position 211 and the second matching position 212 can be set as hole or groove structures cooperating with the ball 452.

[0160] Please continue to refer to FIG. 26-FIG. 31, the second matching structure 40 further comprises a third elastic member 46 connected to the second movable member 44 far away from the first movable member 32, wherein the second movable member 44 can slide up or down along the Z direction under the action of external force, and the third elastic member 46 can be deformed under the action of external force, so that the third elastic member 46 has a tendency to drive the second movable member 44 to move back to the original position. By setting the third elastic member 46, the automatic reset of the second movable member 44 can be realized after the taking action is completed, without the need for manual reset, further improving the convenience of operation.

[0161] In another embodiment, as shown in FIG. 32 and FIG. 33, the assembly hole 21 extends along the X direction, the second movable member 44 is configured as a shaft, and the second movable member 44 is movably connected to the second stacking device 20 and at least partially protrudes from the second stacking device 20. It can be understood that it is also relatively simple to move the second matching member 41 through the shaft. Among them, the second matching member 41 is connected to the circumferential side of the second movable member 44.

[0162] Further, the second movable member 44 can slide in or out along the X direction under the action of external force, so as to switch the first matching member 31 and the second matching member 41 between the matching and non-matching states.

[0163] Exemplarily, the second movable member 44 can slide in along the X direction under the action of external force, that is, under the action of external force, the second matching member 41 moves away from the first matching member 31, and the two are switched from the matching state to the non-matching state, so as to switch the locking state to the unlocking state. Of course, the second movable member 44 can slide out along the X direction under the action of external force, that is, under the action of external force, the second matching member 41 moves away from the first matching member 31, and the two are switched from the matching state to the non-matching state, so as to switch the locking state to the unlocking state. It should be noted that here the first matching member 31 and the second matching member 41 are taken as an example of magnetic attraction matching, and when they are magnetic repulsion matching, only the pulling and pressing modes need to be changed accordingly.

[0164] Further, as shown in FIG. 24, FIG. 25, FIG. 32 and FIG. 33, the first matching member 31 can be arranged on the side of the second matching member 41 along the Z direction. Of course, the first matching member 31 can also be arranged on the side of the second matching member 41 along the Y direction as shown in FIG. 26-FIG. 31, so that the switching of the first matching member 31 relative to the second matching member 41 between the matching and non-matching states can be realized.

The axis direction of the second movable part 44 is perpendicular to the sliding direction of the first movable part 32.

[0167] That is, as shown in FIGS. 34 and 35, when the second movable part 44 rotates, it can move axially through the thread, thereby driving the second cooperating part 41 to move towards or away from the first cooperating part 31. The magnetic attraction or magnetic repulsion mode can be reasonably set according to the actual situation, so as to realize the locking and unlocking of the stacking device.

[0168] Further, the second movable part 44 in the embodiment and the third embodiment, as shown in FIGS. 32-35, can be provided with a force applying end 442 on the part protruding from the second stacking device 20. The force applying end 442 is used to provide a force applying position, so as to facilitate the operator to pull or push the second movable part 44.

The axis direction of the second rotating shaft 443 is the same as the sliding direction of the first movable part 32. The rotating disc is rotated to drive the second cooperating part 41 to rotate relative to the first cooperating part 31, which is also convenient for realizing the magnetic cooperation between the two.

[0170] Further, in the unlocked state, if the second cooperating part 41 and the first cooperating part 31 adopt the magnetic attraction cooperation mode to realize positioning, in order to realize automatic resetting of the second movable part 44 after taking, as shown in FIGS. 39 and 40, the second cooperating structure 40 further includes a fourth elastic part 47, which is configured as a torsion spring. The fourth elastic part 47 is sleeved on the outer periphery of the second rotating shaft 443 and is connected with the second movable part 44 and the second stacking device 20 respectively.
