[0043] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] like Figure 1 The figure shows a connection device 100, which includes a first connection member 11 and a first adapter member 12 that can cooperate with each other. The first connection member 11 is connected to the first carrier and can move together with the first carrier, and the first adapter member 12 is connected to the second carrier and can move together with the second carrier. When the first connection member 11 abuts against the first adapter member 12, the first carrier and the second carrier are connected to achieve relative fixation and can move together. When the first connection member 11 is separated from the first adapter member 12, the first carrier and the second carrier can move relatively freely.

[0045] In order to describe the above structure clearly, the specific structure of the connection device 100 and its working principle are described in detail by taking the storage box as an example. That is, the first connection member 11 is connected to the first type of storage box 30, and the first adapter member 12 is connected to the second type of storage box 40. Of course, the first carrier and the second carrier can also be other items, such as accessories, tools, charging devices, power supply devices, lighting devices, etc. As long as the structure of the present application is set on the item, it can be understood that the item is the carrier connected by the connection device 100.

[0046] like Figure 1Shown is a storage box, which can be used to store items, such as accessories, tools, charging devices, power supply devices, lighting devices, etc. It should be noted that the storage of items described in the present application is not limited to storing items in a storage box, but also includes fixing the items on the outside of the storage box and keeping them relatively fixed with the storage box, which is also referred to as storing the items in the storage box. The storage box includes a box body 31 having a accommodating cavity and an upper cover 32 for closing the above-mentioned accommodating cavity, and items can be stored in the accommodating cavity. The storage box also includes a plurality of side walls 34, and a bottom wall 33 arranged opposite to the upper cover 32. The plurality of side walls 34 and the bottom wall 33 basically form a semi-open accommodating cavity, that is, the plurality of side walls 34, the bottom wall 33 and the upper cover 32 surround the accommodating cavity.

[0047] The first type storage box 30 and the second type storage box 40 mentioned below are only used to clearly describe the structure, and do not limit the types of storage boxes. That is, the first type storage box 30 and the second type storage box 40 can be the same type of storage box or different types of storage boxes.

[0048] In order to clearly explain the technical solution of this application, the following definitions are given: Figure 1 It should be noted that, unless otherwise specified, the above, below, front, back, left, and right mentioned below all refer to the above. Figure 1 The state when it is at rest is shown.

[0049] like Figures 1 to 18 A connecting device 100 is shown, which can connect the first type of storage box 30 with the second type of storage box 40, that is, the first type of storage box 30 and the second type of storage box 40 can be relatively locked with each other through the connecting device 100 in the absence of external force.

[0050] The connection device 100 includes a connection assembly 10, which can be adaptively installed on the first type storage box 30 and the second type storage box 40. The connection assembly 10 includes a first connector 11 and a first adapter 12. When the first connector 11 and the first adapter 12 are in contact, the first type storage box 30 can be connected to the upper side of the second type storage box 40 or the lower side of the second type storage box 40. When the first connector 11 and the first adapter 12 are separated, the first type storage box 30 and the second type storage box 40 can move relatively freely. With this arrangement, when the user places the storage boxes in the storage room, it is convenient to stack them, and the stability of the connection between the storage boxes can be ensured, and they are not easy to tip over. Similarly, when the user places the storage boxes on the transportation vehicle, the stability of the connection between the storage boxes can be ensured during transportation, and the tipping over caused by the bumps during transportation can be avoided.

[0051] The connecting device 100 can be installed on the upper cover 32 or the bottom wall 33 of the storage box, so that the second type storage box 40 can be connected to the upper cover 32 or the bottom wall 33 of the first type storage box 30.

[0052] In some embodiments, the first type of storage box 30 may be connected to wheels, and the wheels may drive the first type of storage box 30 to move. The user may connect the second type of storage box 40 to the upper cover 32 of the first type of storage box 30 through the connection assembly 10, so that when the user moves the first type of storage box 30, the second type of storage box 40 will move together. This arrangement facilitates the user to move the storage box. Of course, it is understandable that the user may connect the third type of storage box to the upper cover 32 of the second type of storage box 40 through the connection assembly 10, and similarly, the fourth type of storage box may be connected to the upper cover 32 of the third type of storage box through the connection assembly 10, that is, the user may stack multiple storage boxes on the storage box according to actual working conditions.

[0053] In order to make the connection between the storage boxes more stable and reliable, multiple connection components 10 can be connected to the storage box, that is, the connection device 100 includes multiple connection components 10. As an embodiment, connection components 10 can be set on both sides of the storage box. Of course, more connection components 10 can be set, or connection components 10 can be set around the storage box.

[0054] The connection device 100 is detachably fixedly connected to the storage box or is integrally formed. As an embodiment, the connection device 100 is detachably connected to the storage box, that is, the user can install the connection device 100 on the storage box according to needs, or remove it and install it on other storage boxes.

[0055] In order to simplify the description, one of the connection components 10 is described as an example below, and the other connection components 10 are basically consistent with their structures. The connection component 10 includes a first connection member 11 and a first adapter member 12. The first connection member 11 has a connection portion 110, and the first connection member 11 is connected to the first type of storage box 30 and can move together with the first type of storage box 30. The first adapter member 12 has an adapter portion 120, and the first adapter member 12 is connected to the second type of storage box 40 and can move together with the second type of storage box 40. It can be understood that the connection portion 110 is fixedly connected to the first connection member 11 or integrally formed, and similarly, the adapter portion 120 is fixedly connected to the first adapter member 12 or integrally formed. The specific connection placement is not limited here, as long as the first connection member 11 can be moved together with the connection portion 110, and the first adapter member 12 can be moved together with the adapter portion 120.

[0056] The connection device 100 has at least a first state, a second state and a third state, and the connection device 100 can switch between these three states. When the connection device 100 is in the second state, the connection portion 110 contacts and abuts the adapter portion 120, the first type storage box 30 and the second type storage box 40 remain relatively fixed, and the second type storage box 40 can move together with the first type storage box 30. When no external force is applied to the first connection member 11, the adapter portion 120 and the connection portion 110 will always remain tightly connected, so that the first type storage box 30 cannot be separated from the second type storage box 40. When the connection device 100 is in the pre-separation state, the connection portion 110 and the adapter portion 120 and the second type storage box 40 are all separated, and the second type storage box 40 is connected to the first type storage box 30. When the connecting device 100 is in the separated state, the connecting portion 110 is separated from the adapting portion 120, the first type storage box 30 is separated from the second type storage box 40, and the first type storage box 30 and the second type storage box 40 can move freely relative to each other. This arrangement can facilitate the removal of the second type storage box 40 from the first type storage box 30.

[0057] The connecting device 100 can be directly switched from the second state to the first state. The connecting assembly 10 also includes a biasing element 111 and a connecting seat 112. The biasing element 111 can provide a biasing force to the first connecting member 11 to move basically in the first direction 101. That is, in the absence of external force, the first connecting member 11 will approach the first adapter 12 due to the biasing force. The connecting seat 112 is basically fixedly connected to the upper cover 32 of the first type storage box 30. The first connecting member 11 is installed on the connecting seat 112, and the first connecting member 11 can move relative to the connecting seat 112. One end of the biasing element 111 abuts against the connecting seat 112, and the other end of the biasing element 111 abuts against the first connecting member 11.

[0058] When the first adapter 12 approaches the first connector 11 and locks with it, the first adapter 12 drives the first connector 11, so that the first connector 11 overcomes the biasing force and moves in a direction substantially opposite to the first direction 101. In this way, when actually in use, the user only needs to move the first adapter 12 downward toward the first connector 11, and the connecting portion 110 on the first connector 11 will automatically lock with the first adapter 12, thereby locking the first type storage box 30 with the second type storage box 40.

[0059] The first adapter 12 includes a driving portion 121, and the driving portion 121 is connected to the adapter 120. In the process of the first adapter 12 moving downwardly close to the first connecting member 11, the driving portion 121 drives the connecting member 110 to move to a position in the direction opposite to the first direction 101. For the convenience of description, this position is defined as the second position. When the first connecting member 11 moves to the second position, the driving portion 121 loses the driving force on the connecting member 110, and the first connecting member 11 moves in the first direction 101 under the action of the bias force until it is locked by the adapter 120. It should be noted that the second position does not refer to a fixed position, but refers to the adapter 120 driving the first connecting member 11 to move to the farthest position in the direction opposite to the first direction 101.

[0060] Specifically, the driving portion 121 is an inclined surface, the adapter portion 120 is a card slot 122, and the connecting portion 110 has a protruding hook 113. When the first adapter 12 approaches the first connecting member 11, the second type of storage box 40 approaches the first type of storage box 30 until they contact. It can also be understood that the inclined surface contacts the hook 113, and the second type of storage box 40 continues to approach the first type of storage box 30. The inclined surface applies a driving force to the first connecting member 11, so that the first connecting member 11 overcomes the biasing force and moves to the second position. At this time, the driving force applied to the hook 113 disappears, and the hook 113 moves in the first direction 101 under the action of the biasing force until the hook 113 is completely engaged with the engaging groove to form a stable connection. When no external force is applied to the first connecting member 11, the biasing element 111 can apply a biasing force to the first connecting member 11 to keep the hook 113 and the card slot 122 in the current state. At this time, the connecting device 100 completes the switching from the second state to the first state. That is to say, if the user wants to achieve a stable connection between the first type storage box 30 and the second type storage box 40, the user only needs to insert the first adapter 12 from top to bottom into the connecting seat 112 of the upper cover 32, and the first connecting member 11 will automatically engage with the first adapter 12 under the action of the driving part 121 and the biasing element 111. The above structure makes it convenient for the user to stably connect the second type storage box 40 to the upper cover 32 of the first type storage box 30.

[0061] In this embodiment, in order to make the connection between the first type storage box 30 and the second type storage box 40 more stable, a plurality of hooks 113 are provided on the first connection member 11. In this embodiment, two hooks 113 are provided on the first connection member, and two slots 122 and inclined surfaces corresponding to the two slots 122 are provided on the corresponding first adapter member 12. In order to make the force on the first connection member 11 uniform, the connection assembly 10 includes two symmetrically arranged biasing elements 111.

[0062] The connection device 100 further includes a stopper assembly 13, which is connected to the connection seat 112. The stopper assembly 13 cooperates with the first connection member 11 so that the connection device 100 can be maintained in the third state. When the connection device 100 switches from the first state to the second state, it needs to pass through the third state, that is, the connection device 100 switches from the first state to the third state first and then switches to the second state.

[0063] The stopper assembly 13 includes a driving member 131, a connecting rod 132, an energy storage element 133, an elastic member 134, a stopper 136 and a fixing member 135. The driving member 131 can be connected to the second carrier, and the driving member 131 can be driven by the second type storage box 40 to move. The stopper 136 can cooperate with the first connecting member 11, so that the connecting device 100 is in the third state. One end of the connecting rod 132 is connected to the driving member 131, and the other end is connected to the stopper 136, so that when the driving member 131 is forced to move, the stopper 136 can be driven by the connecting rod 132 to move basically along the third direction 103. The energy storage element 133 can cooperate with the stopper 136, so as to provide a biasing force for the stopper 136 to move basically in the third direction 103. One end of the energy storage element 133 abuts on the connecting seat 112, and the other end abuts on the stopper 136. The fixing member 135 is used to connect the stopper 136 to the connecting rod 132. One end of the elastic member 134 abuts against the connecting seat 112, and the other end abuts against the driving member 131. The elastic member 134 can give the driving member 131 a biasing force substantially along the fourth direction. The connecting seat 112 is provided with a limiting portion 117, and the limiting portion 117 abuts against the driving member 131.

[0064] In the present application, the third direction and the fourth direction are substantially in the same direction. It can be further understood that the third direction and the fourth direction are both upward directions.

[0065] The first connecting member 11 further includes a toggle portion 114, an abutting portion 115 and a stopper end 116. The toggle portion 114 is used for user operation and is basically arranged between the two connecting portions 110. The abutting portion 115 is used to cooperate with the stopper 136 to put the connecting device 100 in the third state. The stopper end 116 is used to limit the first connecting member 11 from continuing to move in the first direction 101 due to the biasing force. The stopper end 116 can abut against the upper cover 32 of the first type storage box 30 to limit the first connecting member 11 from continuing to move in the first direction 101. When the connecting device 100 in the first state is switched to the second state, the toggle portion 114 is driven, so that the first connecting member 11 is forced to move to the first position in the second direction 102. It should be noted that the first position is a position to which the user drives the toggle portion 114 to move along the second direction 102, and the position is related to the force applied by the user to the toggle portion 114, that is, the first position is not a fixed position. When the connecting device 100 is in the first state, the distance from the first position to the first adapter 12 is greater than the distance from the stopper 136 to the first adapter 12. At the same time, in the process of switching from the second state to the first state, the farthest position that the first connecting member 11 can move is the second position, wherein the distance from the second position to the first adapter 12 is less than the distance from the stopper 136 to the first adapter 12, that is, the second position is between the first position and the first adapter 12. It can also be understood that in the process of switching from the second state to the first state, there is no contact between the first connecting member 11 and the stopper 136. This arrangement allows the driving part 121 to only overcome the biasing force of the biasing element 111 in the process of driving the first connecting member 11 to switch states. In this embodiment, the biasing element 111, the elastic member 134, and the energy storage element 133 are all springs.

[0066] The stopper 136 includes an inclined slope and a stop surface. The abutting portion 115 approaches the stopper 136 and contacts the slope. The user continues to drive the first connecting member 11 to move along the second direction 102. The abutting portion 115 is driven by the force to drive the stopper 136 to compress the energy storage element 133 until the abutting portion 115 completely passes through the slope. The slope loses its driving force. Due to the rebound of the energy storage element 133, the user releases the first connecting member 11 after the first connecting member 11 moves to the first position. The first connecting member 11 rebounds under the force of the biasing element 111 until the abutting portion 115 abuts against the stop surface of the stopper 136. At this time, the first connecting member 11 is kept in the current state, i.e., the third state, due to the action of the stopper 136.

[0067] like Figures 5 and 6As shown, when the connecting device 100 is in the first state, the second type storage box 40 contacts the driving member 131. Due to the gravity of the second type storage box 40, the second type storage box 40 applies a driving force to the driving member 131, so that it overcomes the elasticity of the elastic member 134 and presses the driving member 131 downward. The driving member 131 is forced downward, so that the other end of the connecting rod 132 moves upward, and the stopper 136 is connected to the connecting rod 132. The connecting rod 132 moves upward, thereby driving the stopper 136 to move upward. The user drives the toggle portion 114 to move it along the second direction 102 to the first position, thereby separating the first connecting member 11 from the first adapter 12. In the process of the first connecting member 11 moving to the first position, it is necessary to overcome the biasing force of the elastic member 134 on the stopper 136. When the first connecting member 11 moves to the first position, the user removes the force applied to the first connecting member 11, and the first connecting member 11 moves in the first direction 101 under the biasing force of the biasing element 111 until the stopper 136 contacts and abuts against the abutting portion 115, and the first connecting member 11 stops moving. At this time, the connecting device 100 is in the third state. When the user wants to switch the connection device 100 to the second state, he only needs to remove the second type storage box 40, and the driving member 131 loses the effect of the external force. Due to the elastic force of the elastic member 134, it moves upward until it abuts against the abutment portion 115. One end of the connecting rod 132 connected to the driving member 131 moves upward, and the other end connected to the stopper 136 moves downward, thereby driving the stopper 136 to move downward. The stopper 136 moves downward, that is, the stopper 136 stops the first connection member 11, and the first connection member 11 continues to move in the first direction 101 under the biasing force of the biasing element 111 until the stopper end 116 abuts against the upper cover 32. At this time, the connection device 100 completes the state switching, and the connection device 100 is in the second state. In this embodiment, the driving member 131 and the connecting rod 132 are integrally formed.

[0068] When the user wants to connect and lock the second-category storage box 40 with the first-category storage box 30, he only needs to move the first adapter 12 connected to the second-category storage box 40 downward toward the first connecting member 11. The first connecting member 11 will automatically engage with the first adapter 12 due to the action of the biasing element 111, thereby locking the second-category storage box 40 to the first-category storage box 30. When the user needs to separate the second type storage box 40 from the first type storage box 30, the user needs to drive the toggle portion 114 to move the first connecting member 11 in the direction opposite to the first direction 101 to a position exceeding the stop member 136, and then release the toggle portion 114, so that the first connecting member 11 moves in the first direction 101 under the action of the bias force until it abuts against the stop member 136. At this time, the first connecting member 11 and the first adapter 12 are in a separated state. The user only needs to remove the second type storage box 40 from the upper cover 32 of the first type storage box 30, and the stop member 136 moves downward to cancel the stop on the first connecting member 11. The first connecting member 11 continues to move in the first direction 101 until the stop end 116 abuts against the upper cover 32, thereby completing the separation of the second type storage box 40 from the first type storage box 30.

[0069] A ball 137 is arranged between the first connecting member 11 and the connecting seat 112, that is, the bottom wall of the first connecting member 11 is provided with a slide groove 138 for the movement of the ball 137. Similarly, a slide groove 138 for the movement of the ball 137 is also provided at a relative position of the connecting seat 112. In this way, when the user drives the first connecting member 11, the first connecting member 11 can run more smoothly relative to the connecting seat 112, making the state switching of the connecting device 100 easier to achieve.

[0070] like Figures 19 to 27 As shown, as another embodiment that can realize the mutual locking of the first type storage box 210 and the second type storage box 220, the locking principle of this embodiment is basically the same as that of the above embodiment. The difference lies in the specific structure of the connecting device 200. This solution will be introduced in detail below.

[0071] In order to clearly explain the technical solution of this application, the following definitions are given: Fig.19 It should be noted that, unless otherwise specified, the above, below, front, back, left, and right mentioned below all refer to the above. Fig.19 The state when it is at rest is shown.

[0072] The connecting device 200 includes a first connecting member 231 and a first adapter 232. The first connecting member 231 is connected to the first type of storage box 210, and the first adapter 232 is connected to the second type of storage box 220. When the first connecting member 231 and the first adapter 232 abut against each other, the first type of storage box 210 and the second type of storage box 220 are relatively fixed and can move together. When the first connecting member 231 is separated from the second connecting member, the first type of storage box 210 and the second type of storage box 220 can move relatively freely.

[0073] The first connecting member 231 can move in a direction away from the first adapter 232. During the movement of the first connecting member 231, the connecting device 200 has a first state, a second state and a third state. When the connecting device 200 is in the first state, the first connecting member 231 abuts against the first adapter 232. When the connecting device 200 is in the second connection state, the first connecting member 231 is separated from the first adapter 232. During the process of the connecting device 200 switching from the second state to the first state, the connecting device 200 needs to switch to the third state first and then switch to the first state. That is, it can be understood that the user can directly switch the connecting device 200 from the second state to the first state. When the user needs to switch the connecting device 200 from the first state to the second state, the user needs to first switch the connection state from the first state to the third state and then switch from the third state to the second state. In this embodiment, the direction of the first connecting member 231 away from the first adapter 232 refers to the left and right direction. For the stability of the connection between the first type storage box 210 and the second type storage box 220, as an implementation method, a connecting component 230 can be set on both the left and right sides of the first type storage box 210. Taking the connecting component 230 located on the left side as an example, the first connecting member 231 should move to the left to move the first connecting member 231 away from the first adapter 232, and for the connecting component 230 located on the right side, the first connecting member 231 should move to the right to move the first connecting member 231 away from the first adapter 232.

[0074] When the connecting device 200 switches from the second state to the first state, the principle and structure of the connecting device 200 for switching from the second state to the first state are basically the same and will not be described in detail herein.

[0075] When the connection device 200 switches from the first state to the second state, it needs to go through the third state. Since the principle of the connection device 200 switching from the first state to the second state is basically the same, it will not be repeated here. Only its structure is introduced here.

[0076] The connection device 200 further includes a stopper assembly 240, which is connected to the connection seat 233. The stopper assembly 240 cooperates with the first connection member 231 so that the connection device 200 can be maintained in the third state. When the connection device 200 switches from the first state to the second state, it needs to pass through the third state, that is, the connection device 200 switches from the first state to the third state first and then switches to the second state.

[0077] The stopper assembly 240 includes a driving member 241, a transmission member 242, an energy storage element 243, an elastic member 244, a stopper 245 and a positioning member 246. The driving member 241 can be connected to the second type storage box 220, and the driving member 241 can be driven by the second type storage box 220 to move downward, and the driving member 241 is at least partially fixedly connected to the connecting seat 233. The stopper 245 can cooperate with the first connecting member 231, so that the connecting device 200 is in the third state, and the stopper 245 is at least partially in contact with the transmission member 242. The transmission member 242 is connected to the driving member 241, one end of the driving member 242 is connected to the connecting seat 233, and the other end is in contact with the driving member 241. When the driving member 241 is forced to move, the stopper 245 can be driven by the transmission member 242 to move substantially along the seventh direction. The energy storage element 243 can cooperate with the stopper 245, thereby providing the stopper 245 with a biasing force that basically moves in the eighth direction. One end of the energy storage element 243 abuts against the transmission member 242, and the other end abuts against the stopper 245. Specifically, a groove is provided on the transmission member 242, and the energy storage element 243 is arranged in the groove. At the same time, a through hole is also provided on the transmission member 242, and the stopper 245 can at least partially extend out of the through hole. One end of the elastic member 244 abuts against the connecting seat 233, and the other end abuts against the transmission member 242. The elastic member 244 can provide the transmission member 242 with a biasing force that is basically opposite to the seventh direction. The positioning member 246 is fixedly connected to the connecting seat 233, and the transmission member 242 partially passes through the positioning member 246. In this embodiment, the seventh direction 107 is basically consistent with the up-down direction, and the eighth direction 108 is basically consistent with the front-back direction.

[0078] like Figure 20 to Figure 25As shown, the connection device 200 in this embodiment specifically implements the state switching as follows: the connection device 200 switches from the second state to the first state, and the user's operation method is consistent with the operation method of the first embodiment, that is, the user brings the second type storage box 220 close to the first type storage box 210, so that the first adapter 232 on the second type storage box approaches the connection seat 233 from top to bottom. In the process of approaching the connection seat 233, the first adapter 232 will inevitably contact the first connection member 231, and then drive the first connection member 231 to move in a direction away from the first adapter 232 until the first adapter 232 abuts against the first connection member 231. Thereby, the connection device 200 is switched from the second state to the first state. It should be noted that the process of switching the connection device 200 from the second state to the first state in this embodiment, and the movement of the parts are basically consistent with the process of switching the connection device 200 from the second state to the first state in the first embodiment.

[0079] In this embodiment, the connection device 200 needs to go through the third state during the process of switching from the first state to the second state, that is, the switching process of the connection device 200 is switching from the first state to the third state, and then switching from the third state to the second state. The first connection member 231 includes a connection portion 2311, a toggle portion 2312, an abutment portion 2313 and a stop end 2314. The connection portion 2311 is used to contact and abut with the adapter portion 2321 of the first adapter 232, so that the first type of storage box 210 and the second type of storage box 220 remain relatively fixed. The toggle portion 2312 is used for user operation, and the toggle portion 2312 is basically arranged between the two connection portions 2311. The abutment portion 2313 is used to cooperate with the stop member 245 to put the connection device 200 in the third state. The stop end 2314 is used to limit the first connection member 231 from continuing to move due to the biasing force. The stop end 2314 can abut against the upper cover of the first type storage box 210 to limit the first connection member 231 from continuing to move. When the connection device 200 in the first state is switched to the second state, the toggle portion 2312 is driven, so that the first connection member 231 is forced to move to the first position in a straight line direction 109 away from the first adapter 232. It should be noted that the first position is a position to which the user drives the toggle portion 2312, and the position is related to the force applied by the user to the toggle portion 2312, that is, the first position is not a fixed position. When the connection device 200 is in the first state, the distance from the first position to the first adapter 232 is greater than the distance from the stop member 245 to the first adapter 232.

[0080] The first type of storage box 210 is fixedly connected to the second type of storage box and remains relatively stable. At this time, the second type of storage box 220 is connected to the driving member 241 on the first type of storage box 210. Because the second type of storage box 220 has a certain weight, when the second type of storage box 220 contacts the driving member 241, it will inevitably apply a force to the driving member 241, so that the driving member 241 is forced to move downward. The driving member 241 is connected to the transmission member 242, and then the transmission member 242 is also forced to move downward. The stop member 245 is connected to the transmission member 242, and the stop member 245 will also move downward with the transmission member 242. At this time, the stop member 245 is on the movement path of the abutment 2313. That is to say, when the second type storage box 220 moves away from the top of the first type storage box 210, the driving member 241 loses the external force, and the transmission member 242 connected to the driving member 241 also loses the force. At this time, the transmission member 242 moves upward under the biasing force of the elastic member 244, driving the stop member 245 to move upward together. At this time, the stop member 245 is basically not in the movement path of the abutment portion 2313. It can also be understood that in the process of switching from the second state to the first state, there is no contact between the first connecting member 231 and the stop member 245. This arrangement allows the driving part to only overcome the biasing force of the biasing element in the process of driving the first connecting member 231 to switch states. In this embodiment, the biasing element, the elastic member 244, and the energy storage element 243 are all springs.

[0081] The stopper 245 includes an inclined slope 2451 and a stopper surface 2452. The abutting portion 2313 approaches the stopper 245 and contacts the slope 2451. The user continues to drive the first connecting member 231 to move. The abutting portion 2313 is driven by the force to drive the stopper 245 to compress the energy storage element 243 until the abutting portion 2313 completely passes through the slope 2451. The slope 2451 loses the driving force. Due to the rebound of the energy storage element 243, the first connecting member 231 moves to the first position. The user releases the first connecting member 231. The first connecting member 231 rebounds under the force of the biasing element until the abutting portion 2313 abuts against the stopper surface 2452 of the stopper 245. At this time, the first connecting member 231 is kept in the current state, i.e., the third state, due to the action of the stopper 245.

[0082] The above shows and describes the basic principles, main features and advantages of the present application.
