[0047] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0049] Conveyor devices are widely used in the logistics field. When a large number of goods need to be quickly transferred between different areas, conveyor devices can improve efficiency. Or, in continuous logistics operation links such as production, sorting, and packaging, conveyor devices can ensure the uninterrupted flow of goods.

[0050] Current conveyor devices all automatically and continuously convey goods. Exemplarily, after a forklift transfers the first good at the conveyor outlet, the subsequent goods will automatically continue to be conveyed, requiring continuous operation by the forklift and technicians. In actual application, when some other operations need to be performed on the first good and then the first good is to be put back onto the conveyor device, the subsequent goods have occupied the original position of the first good, and current conveyor devices are difficult to handle the above situation and are difficult to make corresponding adjustments to complex specific operations in actual application.

[0051] In view of this, in a first aspect, please refer to Figures 1 to 5, embodiments of the present application provide a conveying device for conveying a plurality of items to be conveyed, and the conveying device has a first state and a second state. The conveying device includes a conveying base 10, a clamping member 20, a transmission member 30, and a blocking member 40. The conveying base 10 has a conveying surface M1 in the first direction X. The clamping member 20 is connected to the conveying base 10 with adjustable position. The transmission member 30 is rotatably connected to the conveying base 10 around the second direction Y. The transmission member 30 has opposite first end D1 and second end D2, and the second direction Y intersects the first direction X. The blocking member 40 is connected to the conveying base 10 and includes a third end D3 and a fourth end D4 arranged oppositely along the first direction X, and the third end D3 is connected to the second end D2. Among them, both the second end D2 and the third end D3 are inside the conveying base 10. In the first state, the first end D1 is separated from the clamping member 20 and extends beyond the conveying surface M1, and the fourth end D4 extends deep into the conveying base 10. In the second state, the first end D1 is fixed to the clamping member 20 and is inside the conveying base 10, and the fourth end D4 extends beyond the conveying surface M1.

[0052] The conveying device provided by the embodiments of the present application is used to convey a plurality of items to be conveyed simultaneously. Among them, the item to be conveyed can be a box carrying goods, or a pallet carrying a plurality of boxes. In the embodiments of the present application, the item to be conveyed is taken as an example of a pallet carrying a plurality of boxes. It can be understood that there are usually multiple pallets on the conveying device, and each pallet is spaced apart from each other, and the conveying device conveys the pallets continuously.

[0053] The conveying device has a conveying outlet. In the art, a forklift is usually used to transfer and remove the pallet transported to the conveying outlet position at the conveying outlet. For the convenience of description, the position where the pallet that the forklift can take away at the conveying outlet is defined as the first position, and the position of the pallet located on the side of the first position away from the outlet is defined as the second position. The conveying device conveys two pallets, and the two pallets on the conveying device are defined as the first pallet and the second pallet respectively. It should be understood that during the conveying process of the two pallets by the conveying device, the first pallet first passes through the second position and then is conveyed to the first position, and the first pallet can be conveyed smoothly. In this case, the conveying device is in the first state, and the pallet can reach the first position smoothly. When the first pallet is in the first position, the second pallet is in the second position. When the forklift lifts and transfers the first pallet, it is necessary to stop the second pallet at the second position to facilitate the forklift to lift and transfer the first pallet. In this case, the second pallet cannot reach the first position, the conveying device is in the second state, and the pallet cannot reach the first position smoothly.

[0054] The conveying device provided by the embodiment of the present application can be switched between a first state and a second state, so that when the pallet can be smoothly transported to the first position, the remaining pallets can be restricted after the second position, so that the pallet to be transferred can avoid the interference of the remaining pallets and be smoothly transported by the forklift; it can also make the remaining pallets reach the first position in turn and orderly after the pallet at the first position is transported away, and perform other actions by the forklift, ensuring the orderliness and reliability of the pallet conveying.

[0055] Specifically, the conveying device includes a conveying base 10, a blocking member 40 and a transmission member 30 connected to the conveying base 10. The conveying base 10 has a conveying surface M1 in the first direction X. It can be understood that the conveying device transports the pallet along the first direction X. By relying on the settings of the blocking member 40 and the transmission member 30, when there is a pallet at the first position, the pallet at the second position can be limited so that it cannot reach the first position.

[0056] The transmission member 30 includes an opposite first end D1 and a second end D2. The blocking member 40 includes a third end D3 and a fourth end D4 oppositely arranged along the first direction X. The third end D3 is connected to the second end D2. Both the second end D2 and the third section are inside the conveying base 10. In the first state, the fourth end D4 of the blocking member 40 extends deep into the conveying base 10, and the first end D1 is arranged beyond the conveying surface M1. In the second state, the first end D1 is fixed to the engaging member 20 and is inside the conveying base 10, and the fourth end D4 extends beyond the conveying surface M1. In the embodiment of the present application, the first end D1 is arranged within the coverage range of the first position, and the fourth end D4 on the blocking member 40 is at the junction of the first position and the second position.

[0057] The process of the transmission member 30 and the blocking member 40 changing from the first state to the second state is as follows. Initially, the conveying assembly is in the first state. The fourth end D4 of the blocking member 40 extends deep into the conveying base 10, and the fourth end D4 cannot limit the conveyed pallet. In other words, the pallet can smoothly pass through the fourth end D4 to reach the first position. Since initially the first end D1 of the transmission member 30 extends beyond the conveying surface M1, when the pallet reaches the first position, the pallet will exert pressure on the first end D1 and press the first end D1 below the conveying surface M1. During the process of the pallet pressing the first end D1 into the conveying base 10, based on the connection between the second end D2 and the third end D3, the fourth end D4 of the blocking member 40 will extend beyond the conveying surface M1, and the conveying device is converted to the second state. The fourth end D4 extending beyond the conveying surface M1 limits the subsequent pallets, so that the subsequent pallets are restricted to the second position.

[0058] In the embodiment of the present application, the transmission member 30 and the engaging member 20 are provided to enhance the reliability and stability of the conveying device when it is in the second state. Even when there is no tray at the first position, the conveying device can be ensured to be in the second state to limit the tray at the second position.

[0059] Specifically, the engaging member 20 is adjustably connected to the conveying base 10, and the transmission member 30 is rotatably connected to the base around the second direction Y. The transmission member 30 has opposite first end D1 and second end D2. Among them, the second direction Y intersects with the first direction X, preferably the second direction Y is perpendicular to the first direction X. In the first state, the first end D1 on the transmission member 30 is separated from the engaging member 20. When a force is generated on the first end D1 by the tray, the transmission member 30 can rotate under the action of this force, driving the first end D1 to be fixed to the engaging member 20, and at the same time making the fourth end D4 protrude beyond the conveying surface M1. In the second state, the first end D1 on the transmission member 30 is fixed to the engaging member 20, which means that the engaging member 20 has a restraining effect on the transmission member 30 and also has a restraining effect on the blocking member 40. In other words, when the engaging member 20 is fixed to the first end D1 on the transmission member 30, the conveying device will always be in the second state. Only after the engaging member 20 is disengaged from the first end D1 on the transmission member 30 can the engaging member 20 release the restraint on the transmission member 30 and then release the restraint on the blocking member 40.

[0060] The process of the transmission member 30 and the engaging member 20 changing from the first state to the second state is as follows. Initially, the conveying device is in the first state, and the first end D1 on the transmission member 30 is in a separated state from the engaging member 20. When a force is generated on the first end D1 by the tray, the transmission member 30 can rotate under the action of this force, driving the fourth end D4 to protrude beyond the conveying surface and driving the first end D1 to move downward. When the first end D1 contacts the engaging member 20, the first end D1 and the engaging member 20 are clamped and fixed, and the state between the first end D1 on the transmission member 30 and the engaging member 20 changes to a fixed state, and the conveying device changes to the second state.

[0061] Based on the restraining effect of the engaging member 20 on the transmission member 30, the conveying device will always be in the second state, and the tray is restricted at the second position, giving technicians sufficient time to perform various operations on the tray at the first position. Only after the engaging member 20 releases the restraint on the transmission member 30 can the conveying device be converted to the first state and the tray can continue to be conveyed. Due to the settings of the engaging member 20 and the transmission member 30, the stability and reliability of the conveying device in the second state can be improved.

[0062] When the pallet needs to continue to be transported, the first position is vacated. The technician adjusts the position of the engaging member 20 on the conveying base 10, releases the fixation of the engaging member 20 and the first end D1 of the transmission member 30, and first adjusts the state between the engaging member 20 and the first end D1 of the transmission member 30 from the second state to the first state. When the constraint of the engaging member 20 on the transmission member 30 is released, the constraint on the blocking member 40 is also released. The blocking member 40 can be adjusted from the second state to the first state, and the conveying device resumes conveying. When a new pallet reaches the first position, it presses down on the first end D1, and the conveying device is adjusted to the second state again. The fourth end D4 limits the subsequent pallets, and the technician performs corresponding operations. Subsequently, the technician can then adjust the position of the engaging member 20 on the conveying base 10, release the fixation of the engaging member 20 and the first end D1 of the transmission member 30, and the conveying device returns to the second state. This cycle repeats, and the technician can control the time when the conveying device is in the second state according to the actual situation, so as to facilitate the technician to complete the corresponding operations.

[0063] When the engaging member 20 releases the constraint on the first end D1 of the transmission member 30, the engaging member 20 and the transmission member 30 change from the second state to the first state. At the same time, the first position is vacated. After the first end D1 is not affected by the gravity of the pallet, the blocking member 40 can change from the second state to the first state. In one embodiment, a reset structure can be provided on the transmission member 30 and the conveying base 10. The reset structure can drive the linkage member to be in the first state without external force. The reset structure can be set as a spring, and the spring force is relied on to drive the linkage member to be in the first state; or the reset structure can be set as a magnetic structure, and the magnetic attraction or repulsion of the magnetic structure is relied on to drive the linkage member to be in the first state. In another embodiment, a corresponding arc structure can be provided at the fourth end D4. When there is no external force acting on the transmission member 30 and the blocking member 40, the blocking member 40 cannot successfully block the pallet at the second position, and the pallet transports itself, forcing the conveying device to change to the second state.

[0064] In summary, in the embodiment of the present application, the conveying device is used to convey multiple items to be conveyed simultaneously. The first position and the second position are defined at the conveying outlet. The first position is closer to the outlet. The conveying device can switch between the first state and the second state, so that when the item to be conveyed can be smoothly conveyed to the first position, the remaining items to be conveyed can be restricted behind the second position, enabling the item to be transported to be transferred by the forklift smoothly without being interfered by the remaining items to be conveyed; and after the item to be conveyed at the first position is transferred away, the remaining items to be conveyed can reach the first position in an orderly manner and be operated by the forklift for other actions, ensuring the orderliness and reliability of the conveyance of the items to be conveyed. At the same time, by providing the engaging member 20 and the transmission member 30, the technician can control the time when the conveying device is in the second state according to the actual situation, so as to facilitate the technician to complete the corresponding operations.

[0065] In some embodiments, the conveying device further includes a plurality of conveying rollers that are arranged side by side at intervals along the first direction X and are rotatably connected to the conveying base 10 around the second direction Y. At least part of the transmission member 30 is located in the gap formed by the conveying rollers. The same side surfaces of the plurality of conveying rollers in the third direction Z and at least part of the surface of the transmission member 30 together form a conveying surface M1, and the third direction Z, the second direction Y, and the first direction X intersect pairwise.

[0066] The tray can be at least on two conveying rollers at the same time to achieve the forward transportation of the tray on the conveying device. At the same time, the conveying surface M1 is formed by a plurality of spaced conveying rollers. While being able to stably transport the tray, a gap is formed on the conveying surface M1 to facilitate the arrangement of other structures.

[0067] At least part of the transmission member 30 is located in the gap formed by the conveying rollers. When the tray is normally transported on the conveying rollers, it can trigger the transmission member 30 located in the gap, causing the conveying device to switch from the first state to the second state. Further, rotatably connecting the conveying rollers to the conveying base 10 can reduce the friction force of the tray during transportation, and more of the kinetic energy of the tray transportation acts on the transmission member 30, improving the effect of the tray on the transmission member 30 and ensuring the smooth conversion of the conveying device from the first state to the second state.

[0068] In some embodiments, the transmission member 30 includes a rotating member 31 and a connecting member 32 that are connected to each other. The rotating member 31 is arranged along the second direction Y and is rotatably connected to the conveying base 10 around the second direction Y. The connecting member 32 is arranged along the first direction X. The first end D1 and the second end D2 are at both ends of the connecting member 32 along the first direction X, and the second end D2 is connected to the rotating member 31. The connecting member 32 is located in the middle of the conveying base 10 along the second direction Y.

[0069] The rotating member 31 is arranged along the second direction Y, and the connecting member 32 is arranged along the first direction X, so that the rotating member 31 is adapted to the extending direction of the conveying roller for facilitating the rotational connection with the conveying base 10. At the same time, the connecting member 32 is adapted to the conveying direction of the tray for facilitating the pressing of the tray against the connecting member 32. Further, arranging the connecting member 32 at the middle of the conveying base 10 along the second direction Y can increase the probability of contact between the tray and the connecting member 32 and ensure the stability of the pressing action between the tray and the connecting member 32. The inclination direction of the connecting member 32 in the first state is inclined upward along the advancing direction of the tray conveyance, which can form a guide for the pressing of the tray against the connecting member 32 and improve the smoothness of the movement of the connecting member 32. At the same time, arranging the rotating member 31 can also facilitate the connection of the second end D2 and the third end D3. Both the second end D2 and the third end D3 are connected to the rotating member 31 to realize the linkage between the second end D2 and the third end D3. Further, for facilitating the arrangement of other structures, the second end D2 and the third end D3 can be arranged at intervals on the rotating member 31 to avoid other structures.

[0070] In some embodiments, the transmission member 30 extends along the axial direction of the transmission roller. The transmission member 30 includes a fifth end and a sixth end that are oppositely arranged along the axial direction of the conveying roller. The third end D3 is connected to one of the fifth end or the sixth end. In the first state, one of the fifth end or the sixth end extends beyond the conveying surface M1. In the second state, both the fifth end and the sixth end are inside the conveying base 10.

[0071] Arranging the transmission member 30 along the axial direction of the conveying roller can increase the length of the transmission member 30 in the second direction Y, which can also increase the contact surface between the transmission member 30 and the tray, so that the tray can act on the transmission member 30 more stably. The transmission member 30 includes a fifth end and a sixth end that are oppositely arranged in the second direction Y. In the first state, one of the fifth end or the sixth end extends beyond the conveying surface M1. It can be understood that the linkage member in the first state is in an inclined state, and at least one end of the transmission member 30 is higher than the conveying surface M1 to contact with the tray.

[0072] After the transmission member 30 contacts the tray, the tray presses down the end that is higher than the conveying surface M1, so that the transmission member 30 is all inside the conveying base 10, and the transmission member 30 is converted to the second state, and then subsequent actions are caused. When the transmission member 30 moves under the action of the tray, the action amplitude of its two ends is the largest, and the corresponding action caused is the strongest, that is, the action amplitude of the fifth end or the sixth end is the largest. Therefore, the third end D3 is connected to the fifth end or the sixth end to be able to trigger subsequent actions to the greatest extent.

[0073] In some embodiments, please refer to Figures 1 to 6, the engaging member 20 has an engaging position and a releasing position, and the first end D1 of the connecting member 32 is fixed to the engaging member 20 in the engaging position. The engaging member 20 is rotatably connected to the conveying base 10 in the second direction Y, and the engaging member 20 rotates between the engaging position and the releasing position. The conveying device further includes an auxiliary assembly 50, which urges the engaging member 20 to be in the engaging position, and the engaging member 20 is adjusted from the engaging position to the releasing position under an external force.

[0074] Based on the fact that the engaging member 20 is adjustably connected to the conveying base 10, the engaging member 20 has an engaging position and a releasing position. When the engaging member 20 is in the engaging position, there is an intersection between the engaging member 20 and the rotation space of the connecting member 32, the connecting member 32 can be fixed to the engaging member 20, and the engaging member 20 can impose a constraint on the connecting member 32. When the engaging member 20 is in the releasing position, there is no intersection between the engaging member 20 and the rotation space of the connecting member 32, the connecting member 32 cannot be fixed to the engaging member 20, and the engaging member 20 releases the constraint on the connecting member 32.

[0075] Considering the spatial factor of the movement of the engaging member 20 between the engaging position and the releasing position, the engaging member 20 is rotatably connected to the transmission base in the second direction Y, and the engaging member 20 rotates between the engaging position and the releasing position. In other embodiments, the engaging member 20 can also be slidably connected to the conveying base 10, and the engaging member 20 slides between the engaging position and the releasing position.

[0076] Regarding the power for driving the engaging member 20 to adjust between the engaging position and the releasing position, it can be specifically set according to the actual situation. When the use scenario allows the use of a power source, the engaging member 20 can be driven by a motor. Or, when the use scenario allows the use of a gas source, the engaging member 20 can be driven by a cylinder. Or, when the use scenario does not allow the use of a power source and a gas source, it can be manually driven by a technician.

[0077] Furthermore, the conveying device provided by the embodiment of the present application further includes an auxiliary assembly 50 for urging the engaging member 20 to be in the engaging position. It can be understood that the engaging member 20 can be adjusted between the engaging position and the releasing position. When the conveying device is in the first state, the engaging member 20 should be in the engaging position and can be fixedly connected to the engaging member 20 during the rotation of the transmission member 30, so that the conveying device is transformed into the second state. When an external force acts, the engaging member 20 is adjusted from the engaging position to the releasing position, and the engaging member 20 is separated from the transmission member 30, and the conveying device will be transformed from the second state to the first state. When the external force disappears, the engaging member 20 can return from the releasing position to the engaging position under the action of the auxiliary assembly 50 so as to be fixed during the next rotation of the transmission member 30.

[0078] In some embodiments, please refer to Figures 1 to 7The connection points between the engaging member 20 and the transfer base 10 and the connection points between the rotating member 31 and the transfer base 10 are aligned in the third direction Z. The third direction Z, the second direction Y, and the first direction X intersect in pairs. The engaging member 20 includes a first connecting portion 21, which extends along the third direction Z. The connecting member 32 includes a main body 321 and a bent portion 322, which is connected to each other. The bent portion 322 is bent along the extension direction of the main body 321 toward the first connecting portion 21, and the bent portion 322 is engaged with the first connecting portion 21.

[0079] In order to save space on the transfer base 10 in the third direction Z and reduce the size of the transfer base 10 in the third direction Z, the connection position between the engaging member 20 and the transfer base 10 and the connection position between the rotating member 31 and the transfer base 10 are flush in the third direction Z. The third direction Z, the second direction Y, and the first direction X intersect in pairs. The first direction X and the second direction Y can be within a horizontal plane, and the third direction Z can be set to a vertical direction.

[0080] The engaging member 20 includes a first connecting portion 21 that is engaged and fixed with the connecting member 32. The first connecting portion 21 extends along the third direction Z. It is understood that the first connecting portion 21 extends from the connection point between the engaging member 20 and the transfer base 10 in the third direction Z. As a solid structure, the first connecting portion 21 also has corresponding dimensions in the second direction Y and the first direction X. Considering that the connecting member 32 is engaged with the engaging member 20 from above, it is emphasized that the engaging member 20 has a predetermined dimension in the third direction Z to enable the connecting member 32 to engage with the engaging member 20.

[0081] The connecting member 32 includes a main body 321 and a bent portion 322. The main body 321 serves as the main portion of the connecting member 32 and primarily controls the rotation radius of the transmission member 30, thereby forming a rotational space for the transmission member 30. The bent portion 322 is primarily configured to engage with the first connecting portion 21. During rotation of the transmission member 30, the bent portion 322 engages the first connecting portion 21 from the obliquely upper portion thereof. The bent portion 322 is configured to bend toward the first connecting portion 21 along the extension direction of the main body 321, thereby facilitating the engagement between the bent portion 322 and the first connecting portion 21.

[0082] In some embodiments, a snap-fitting hole 323 is provided on the connecting member 32, and the snap-fitting hole 323 includes a first part located on the main body 321 and a second part located on the bending portion 322 and connected to the first part. The bending portion 322 forms a snap-fitting side on the side of the second part away from the first part, and the first connecting portion 21 can be located inside the snap-fitting hole 323 and abut against the snap-fitting side.

[0083] Furthermore, to enhance the ease and stability of the engagement between the connector 32 and the engaging member 20, an engagement hole 323 is provided on the connector 32. The first portion of the engagement hole 323 is located on the main body 321. During the engagement process, the first portion provides a certain degree of relief for the first connector 21, facilitating the engagement of the first connector 21 into the engagement hole 323. The second portion of the engagement hole 323 is located on the bend 322 and primarily accommodates the engagement end of the first connector 21. Furthermore, when the engagement end of the first connector 21 is within the engagement hole 323, it abuts against the engagement side, reducing the probability of automatic disengagement between the first connector 21 and the connector 32.

[0084] In some embodiments, see Figures 1 to 8 A guide slope 211 is provided on the side of the first connection portion 21 that first contacts the bent portion 322. The guide slope 211 is inclined along the rotation trajectory of the bent portion 322. During the rotation of the transmission member 30, the bent portion 322 is clamped to the first connection portion 21 from the oblique upper side of the first connection portion 21. The bent portion 322 can be clamped to the first connection portion 21 along the inclined direction of the guide slope 211. The guide slope 211 can guide the movement trajectory of the clamping connection between the bent portion 322 and the first connection portion 21 to a certain extent, thereby improving the smoothness of the clamping connection between the bent portion 322 and the first connection portion 21.

[0085] In some embodiments, a relief groove 212 is provided in the middle of the first connecting portion 21 along the third direction Z, and the end of the bent portion 322 facing away from the main body 321 can be located within the relief groove 212. When the bent portion 322 is clipped onto the first connecting portion 21, the bent portion 322 will interfere with the first connecting portion 21 to a certain extent based on its original extension direction. The provision of the relief groove 212 can avoid some structures on the bent portion 322. At the same time, after the bent portion 322 is extended, the intersection area between the bent portion 322 and the first connecting portion 21 is increased, thereby improving the clipping stability between the bent portion 322 and the first connecting portion 21.

[0086] In some embodiments, the engaging member 20 includes a second connecting portion 22 , and the auxiliary component 50 includes an elastic member 51 connected to the transfer base 10 . The elastic member 51 is connected to the second connecting portion 22 , and the elastic force of the elastic member 51 drives the engaging member 20 to be in the engaging position.

[0087] The engaging member 20 is provided with a second connecting portion 22 , which is used to connect with the auxiliary component 50 so as to drive the engaging member 20 to return to the engaging position in the absence of external force.

[0088] Specifically, the auxiliary component 50 includes an elastic member 51 connected to the transmission base. The elastic member 51 is connected to the second connecting portion 22, and the elastic force of the elastic member 51 drives the engaging member 20 to be in the engaged position. Alternatively, in other embodiments, the auxiliary component 50 may be provided as a magnetic member, which includes a first magnet and a second magnet respectively disposed on the transmission base 10 and the second connecting portion 22.

[0089] In some embodiments, the auxiliary component 50 further includes a connecting post 52 fixedly connected to the transmission base 10 and extending along the third direction Z. A connecting hole 221 is provided on the second connecting portion 22, and the connecting post 52 passes through the connecting hole 221. The diameter of the connecting post 52 is smaller than the diameter of the connecting hole 221 so that the second connecting portion 22 has a preset movement space relative to the connecting post 52. The elastic member 51 is sleeved on the connecting post 52 and connected to the second connecting portion 22.

[0090] To limit the rotation range of the engaging member 20, a connecting post 52 is provided on the transmission base 10, a connecting hole 221 is provided on the second connecting portion 22, the connecting post 52 passes through the connecting hole 221, and the diameter of the connecting post 52 is smaller than the diameter of the connecting hole 221, so that the second connecting portion 22 can move relative to the connecting post 52 within a certain space to complete the adjustment between the engaged position and the released position of the engaging member 20. At the same time, when the elastic member 51 is sleeved on the connecting post 52, the connecting post 52 can also position the elastic member 51 to avoid the offset of the elastic member 51.

[0091] In some embodiments, the elastic member 51 is provided as a spring, and the spring is sleeved on the connecting post 52. Considering the different sizes of the connecting post 52 and the connecting hole 221, gaskets can be provided at both ends of the spring to prevent the spring from extending into the connecting hole 221. Alternatively, the elastic member 51 is provided as a rubber pad, and the rubber pad is disposed on one side of the connecting post 52 to drive the engaging member 20 to be in the engaged position.

[0092] In some embodiments, a limiting block 53 is connected to the connecting post 52. One end of the elastic member 51 is connected to the second connecting portion 22, and the other end of the elastic member 51 is connected to the limiting block 53. The limiting block 53 has different preset heights along the third direction Z on the connecting post 52, so as to adjust the extension dimension of the elastic member 51 in the third direction Z and adjust the elastic force of the elastic member 51. Specifically, the connecting post 52 can be directly provided as a bolt, and the limiting block 53 is provided as a nut, and the nut is threadedly connected to the bolt, and the spring is located between the nut and the second connecting portion 22.

[0093] In some embodiments, the locking member 20 also includes a rotating portion 23 connected to the conveying base 10 in a ring-shaped second direction Y, and the rotating portion 23 extends along the second direction Y. The first connecting portion 21 and the second connecting portion 22 are both connected to the rotating portion 23 and are spaced apart in the second direction Y to form an offset space for easy connection with the remaining structures.
