Moreover, the power supply channel 14 in the present invention has the same extension direction as the bus body 1, which makes it convenient for the power supply device to supply power at different positions of the bus body 1. In addition, the present invention detachably connects adjacent bus bodies 1 through a body connector, and electrically connects corresponding power transmission parts 13 in adjacent bus bodies 1 through a power transmission part connector, thereby ensuring that the corresponding power transmission parts 13 in adjacent bus bodies 1 are in an electrically conductive state, so that the power supply device can be plugged into the power supply channel 14 at any position of the bus body 1 to complete the power supply work, without the need to rearrange the power distribution system of the workshop, and can adapt to the increase, decrease or movement of workshop equipment.

[0021] In this embodiment, the power transmission part connector can be implemented in a variety of ways such as conductive wire connection, conductive plate connection, etc. Preferably, a first insulating partition 21 is provided between adjacent power transmission parts 13 on the side close to the end connection assembly, and the power transmission part connector includes a power transmission splint 22, which is provided between the first insulating partition 21 and the power transmission part 13, and the two ends of the power transmission splint 22 are respectively abutted against the corresponding power transmission parts 13 provided in the adjacent busbar body 1. The power transmission part connector of this embodiment adopts the power transmission splint 22 for power transmission, and a power transmission splint 22 is provided on both sides of each power transmission part 13, and the adjacent power transmission splints 22 are insulated by the first insulating partition 21, so as to ensure that the corresponding power transmission parts 13 provided in the adjacent busbar body 1 are in an electrically conductive state, but the adjacent power transmission parts 13 in the same busbar body 1 are in an insulated state.

[0022] In a further optimized solution, the main body connector includes a first clamping plate 23 and a second clamping plate 24, which are respectively arranged on both sides of the busbar body 1 near one end of the end connection assembly, and the first clamping plate 23 and the second clamping plate 24 are both detachably connected to the adjacent busbar body 1, and the first clamping plate 23, the second clamping plate 24, the power transmission part 13, the first insulating partition 21 and the power transmission clamping plate 22 are parallel to each other and are fastened and connected by bolts and nuts. In this embodiment, the power transmission part 13, the first insulating partition 21 and the power transmission clamping plate 22 are connected together by the first clamping plate 23, the second clamping plate 24 and the combination of bolts and nuts, and the two ends of the first clamping plate 23 are detachably connected to the adjacent busbar body 1, and the two ends of the second clamping plate 24 are detachably connected to the adjacent busbar body 1, so as to realize the detachable connection of the adjacent busbar bodies 1 and the electrical connection of the corresponding power transmission parts 13 arranged in the adjacent busbar bodies 1.

[0023] In this embodiment, the first clamping plate 23, the second clamping plate 24, the first insulating partition 21 and the power transmission clamping plate 22 are all provided with through holes at a corresponding position in the middle, and the through holes are provided between the power transmission parts 13 correspondingly provided in the adjacent busbar bodies 1. The bolts and nuts include bolts 25 and nuts 26, the outer side of the bolts 25 is sleeved with insulating sleeves 27, the bolts 25 and the insulating sleeves 27 pass through the corresponding through holes, and the two ends of the bolts 25 are fastened by nuts 26, that is, by rotating the nuts 26, an extrusion force is applied to the first clamping plate 23 and the second clamping plate 24, so that the first clamping plate 23, the second clamping plate 24, the power transmission part 13, the first insulating partition 21 and the power transmission clamping plate 22 are connected together. In some embodiments, the first clamping plate 23 and the second clamping plate 24 are C-shaped structures, the two side wings of the first clamping plate 23 and the two side wings of the second clamping plate 24 are correspondingly arranged, and the first plate and the second plate are detachably connected between the corresponding side wings, and the first plate and the second plate are arranged on the other two sides of the combination (power transmission part 13, first insulating partition 21 and power transmission clamping plate 22). The first clamping plate 23, the second clamping plate 24, the first plate and the second plate are surrounded to form a complete shell, which surrounds the combination (power transmission part 13, first insulating partition 21 and power transmission clamping plate 22), and only two ports are retained to ensure that the end of the busbar body 1 is inserted into the shell.

[0024] In this embodiment, the busbar body 1 is divided into a straight busbar body and a bent busbar body. The straight busbar body is a straight structure, and the bent busbar body is a bent structure, that is, the bent busbar body includes two split busbar bodies that are fixedly connected, and the two split busbar bodies are arranged at a certain angle. Preferably, the angle between the two split busbar bodies is 90 degrees, that is, the two split busbar bodies are arranged vertically to achieve the turning of the transmission bus. By combining the straight busbar body, the bent busbar body and the end connection assembly, a complete transmission busbar is formed to adapt to workshops or other application spaces with different structures.

[0025] In a further optimized solution, the busbar body 1 is detachably connected with a sealing plate 15 on one side where the power-taking channel 14 is in communication with the external space, and an insulating support 151 is provided at one end of the sealing plate 15 close to the power-taking channel 14, and the insulating support 151 is clamped with the power-taking channel 14. The present invention separates the power-taking channel 14 from the external space by the sealing plate 15, thereby playing a sealing role; at the same time, the insulating support 151 in the sealing plate 15 is clamped with the power-taking channel 14, and the power transmission part 13 in the same busbar body 1 is supported by the insulating support 151, further ensuring that the power transmission part 13 is arranged at intervals, and preventing the power transmission part 13 from falling off from the insulating sheath 12 during transportation.

[0026] Preferably, the insulating support member 151 adopts an arrow-shaped structure, that is, the insulating support member 151 includes a support plate fixedly connected to the sealing plate 15, and the support plate and the sealing plate are arranged vertically, and two abutment plates are fixedly provided on one side of the support plate away from the sealing plate 15, and the two abutment plates are respectively abutted and connected with the power transmission part 13. The arrow-shaped insulating support member 151 is easy to insert into the power taking channel 14, and it can be checked whether the power transmission part 13 is installed in the corresponding position.

[0027] A further optimized solution is that the power transmission part 13 is a copper busbar, and a groove for accommodating the copper busbar is provided on the insulating sheath 12. Copper has excellent electrical conductivity. In this embodiment, a copper busbar is used as the power transmission part 13, and the groove on the insulating sheath 12 is used to limit the position of the copper busbar. Preferably, the busbar body 1 is fixedly provided with a plurality of snap-in plates in the conductive cavity 11 and at the end thereof, and the insulating sheath is provided with grooves or protrusions adapted to the snap-in plates, and a detachable connection between the conductive cavity 11 and the insulating sheath 12 is achieved through this snap-in relationship. In this embodiment, the snap-in relationship between the copper busbar and the insulating sheath 12 is not changed, and only the cross-sectional area of ​​the copper busbar is changed, so that different configurations of copper busbars are used for different power consumptions, thereby achieving step changes and saving overall costs.

[0028] The present invention also discloses a power transmission bus distribution system, including a power transmission bus and a plug-in box 3, wherein the plug-in box 3 and the power transmission bus are detachably connected, and a plurality of groups of plug connectors 31 are arranged inside the plug-in box 3, wherein the conductive ends of the plug connectors 31 are clamped in the power taking channel 14, and the conductive ends of the plug connectors 31 are abutted against the two power transmission parts 13, and the output end of the plug connector 31 is electrically connected to a plug 32.

[0029] The plug box 3 in this embodiment is a power-taking device, and the plug box 3 is a key structure for taking power from the power transmission bus. In this embodiment, the conductive end of the plug connector 31 is clamped in the power-taking channel 14, and the conductive end of the plug connector 31 is abutted against the two power transmission parts 13. Since the two power transmission parts 13 in the same conductive cavity 11 have opposite polarities, the plug connector 31 obtains the power transmitted in the two power transmission parts 13 through the conductive end, and transmits the obtained power through the plug 32 electrically connected to its output end, thereby completing the power taking work; and since a number of independent but electrically conductive power transmission parts 13 are arranged inside the power transmission bus, the power extraction work can be realized by detachably connecting the plug box 3 to any position of the bus body 1, and there is no need to rearrange the power distribution system of the workshop, and it can adapt to the increase, decrease or movement of workshop equipment.

[0030] The plug connector 31 in this embodiment has two independent power transmission structures, which are electrically connected to the two power transmission parts 13 in the same busbar body 1 respectively. The plug connector 31 in this embodiment can realize the power transmission between the plug connector 31 and the power transmission part 13 through structures such as wires and cables. In a further optimized solution, the plug connector 31 includes a second insulating partition 311, and the second insulating partition 311 is provided with abutting conductive sheets 312 on both sides close to the power transmission part 13. The two abutting conductive sheets 312 abut against the two power transmission parts 13 respectively, and the two abutting conductive sheets 312 are electrically connected to the plug 32. The power transmission part 13 in this embodiment adopts a copper busbar, which is a plate-shaped structure. In this embodiment, the power transmission is realized by abutting the abutting conductive sheet 312 against the power transmission part 13, and the two abutting conductive sheets 312 are insulated by the second insulating partition 311 to prevent a short circuit caused by the contact of the two abutting conductive sheets 312.

[0031] In this embodiment, the abutting conductive sheet 312 is made of an elastic sheet, and the abutting conductive sheet 312 adopts a continuous wavy structure, which improves the elasticity of the abutting conductive sheet 312, ensures that the abutting conductive sheet 312 is in close contact with the power transmission unit 13, and ensures power supply safety. In this embodiment, the plug connector 31 also includes a third insulating plate 313, and the number of third insulating plates 313 in each group of plug connectors 31 is 2, and they are respectively arranged on the side of the abutting conductive sheet 312 away from the second insulating partition 311, and the insulation work of the abutting conductive sheet 312 is achieved by the second insulating partition 311 and the third insulating plate 313. A copper plate is arranged between the third insulating plate 313 and the abutting conductive sheet 312, and the copper plate is detachably connected to the wire nose, and the power obtained by the abutting conductive sheet 312 is transmitted out through the wire nose; in this embodiment, the third insulating plate 313 and the copper plate are used to ensure that one end of the abutting conductive sheet 312 is relatively fixed, and further ensure that the shape of the abutting conductive sheet 312 does not change. Of course, the plug 32 in this embodiment is an industrial plug. In some embodiments, a switch, an electrical component, etc. are electrically connected between the plug connector 31 and the plug 32 to further ensure the safety of electricity use.

[0032] Further optimization scheme, a connection plate 16 is fixedly provided on the side of the busbar body 1 away from the power taking channel 14, and the connection plate 16 is detachably connected to the ceiling structure 4. When installing this embodiment, the staff designs the direction of the transmission busbar and various installation matters according to the different workshops or actual installation spaces and the power demand at different locations, and installs the ceiling structure 4 on the top of the workshop or the actual installation space, and then realizes the installation of the transmission busbar through the detachable connection between the connection plate 16 and the ceiling structure 4, and realizes the power extraction work through the detachable connection between the plug-in box 3 and any position of the busbar body 1, without rearranging the power distribution system of the workshop, and can adapt to the increase, decrease or movement of workshop equipment.

[0033] Preferably, the plug-in box 3 and the busbar body 1 are slidably connected, and a guide plate 33 is detachably connected to one side of the plug-in box 3 close to the busbar body 1. The guide plate 33 is arranged along the extension direction of the busbar body 1, and two groups of guide plates 33 are provided and respectively arranged on both sides of the busbar body 1. In this embodiment, the plug-in box 3 and the busbar body 1 are slidably connected, and since the power-taking channel 14 and the busbar body 1 extend in the same direction, the position adjustment of the plug-in box 3 on the busbar body 1 can be achieved by sliding, and the process can be completed without powering off. During installation, the alignment and guiding work of the plug-in box 3 and the busbar body 1 are achieved by two guide plates 33, reducing the difficulty of installing the plug-in box 3 and the busbar body 1. Preferably, the guide plate 33 is an elastic plate, and the distance between the guide plate 33 and the busbar body 1 gradually decreases from the busbar body 1 to the plug-in box 3, that is, the distance between the two guide plates 33 is the largest at the installation port position, ensuring the guiding effect of the guide plate 3.

[0034] According to a further optimization scheme, the two ends of the plug-in box 3 are detachably connected with a locking mechanism, which includes a mounting plate 51, a clamping member 52 and a driving member 53; the mounting plate 51 is detachably connected to the end of the plug-in box 3, and two groups of clamping members 52 are provided and are both slidably connected to the mounting plate 51, and the two groups of clamping members 52 are symmetrically arranged about the first axis; the clamping member 52 includes a pressing portion 521 that abuts and presses against the busbar body 1; the driving member 53 is slidably connected to the mounting plate 51 and the sliding direction of the two is the direction of the first axis, and the connection between the clamping member 52 and the driving member 53 is respectively a first connecting surface 522 and a second connecting surface 531, and along the first axis toward the direction of the pressing portion 521, the vertical distance between the first connecting surface 522 and the first axis gradually decreases; based on the sliding of the driving member 53, the second connecting surface 531 applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522, and the sliding trajectory of the clamping member 52 is perpendicular to the first connecting surface 522. In this embodiment, the busbar body 1 includes a protrusion that abuts and presses against the pressing portion 521 .

[0035] When the present invention is working, the driving member 53 slides along the first axis direction, and the second connecting surface 531 applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522, and the clamping member 52 is connected to the mounting plate 51 by sliding along the sliding track direction, and the sliding track of the clamping member 52 is perpendicular to the first connecting surface 522, so the force applied by the second connecting surface 531 to the first connecting surface 522 drives the clamping member 52 to move along the sliding track direction, and because the two groups of clamping members 52 are symmetrically arranged about the first axis, under the action of the driving member 53, the distance between the pressing parts 521 increases or decreases, so that the pressing part 521 of the clamping member 52 abuts against and clamps the busbar body 1 or loosens the busbar body 1, thereby quickly realizing the disassembly and assembly work between the mounting plate 51 and the busbar body 1.

[0036] A further optimized solution is that the clamping member 52 is provided with a first slide rail 523 along the extension direction of the first connecting surface 522, the first slide rail 523 and the driving member 53 are slidably connected, the first connecting surface 522 and the second connecting surface 531 are respectively the contact surfaces of the first slide rail 523 and the driving member 53, and the contact surfaces of the driving member 53 and the first slide rail 523; the clamping member 52 is provided with a first slide groove 524 along the direction of its sliding track, a first sliding rod 525 is slidably arranged in the first slide groove 524, and the first sliding rod 525 and the mounting plate 51 are detachably connected. When the present embodiment is working, since the first slide rail 523 and the driving member 53 are slidably connected, when the driving member 53 slides along the first axis, the position of the driving member 53 relative to the first slide rail 523 will change, that is, the abutment area of ​​the first connecting surface 522 and the second connecting surface 531 changes. However, under the restriction of the sliding connection between the first connecting surface 522 and the second connecting surface 531, the second connecting surface 531 continuously applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522, and the pressing member 52 is constrained by the driving member 53, so the pressing member 52 cannot be released. The first slide groove 524 and the first sliding rod 525 provide the clamping member 52 with the degree of freedom along the sliding track direction, so the clamping member 52 moves along the sliding track direction under the force applied by the second connecting surface 531 to the first connecting surface 522, and because the two groups of clamping members 52 are symmetrically arranged about the first axis, under the action of the driving member 53, the distance between the pressing parts 521 increases or decreases, so that the pressing parts 521 of the clamping member 52 abut against and clamp the busbar body 1 or release the busbar body 1, thereby quickly realizing the disassembly and assembly work between the mounting plate 51 and the busbar body 1. Of course, the present embodiment can also adopt other methods to realize that the driving member 53 drives the clamping member 52 to move along the sliding track direction, such as electric cylinder, air cylinder and other driving structures, but compared with the driving structure adopted in the present application, it does not require electric drive, and manual operation is sufficient, which is convenient and easy.

[0037] In this embodiment, the first connection surface 522 and the second connection surface 531 can adopt curved surface contact, plane contact or anisotropic surface contact. Preferably, the two ends of the motion trajectory of the driving member 53 are respectively the first end and the second end: the first end is the end of the motion trajectory of the driving member 53 close to the pressing portion 521, when the driving member 53 is located at the first end, the distance between the two pressing portions 521 is the first distance; when the driving member 53 is located at the second end, the distance between the two pressing portions 521 is the second distance, and the first distance is greater than the second distance; the first connection surface 522 and the second connection surface 531 are both planes, and the distance from the first connection surface 522 to the first axis gradually increases from the first end to the second end. In this embodiment, by controlling the change in the distance from the first connecting surface 522 to the first axis, a certain angle is formed between the first connecting surface 522 and the first axis, and the first connecting surface 522 is arranged tilted, thereby ensuring that the first connecting surface 522 and the second connecting surface 531 are in tilted contact with each other. When the driving member 53 slides along the direction of the first axis, the second connecting surface 531 applies a force perpendicular to the direction of the first connecting surface 522 to the first connecting surface 522.

[0038] In this embodiment, when the driving member 53 is located at the first end, the distance between the two pressing portions 521 is the first distance; when the driving member 53 is located at the second end, the distance between the two pressing portions 521 is the second distance, and the first distance is greater than the second distance; therefore, when the driving member 53 moves between the first end and the second end of the motion trajectory, the distance between the two pressing portions 521 also increases or decreases. The present invention can determine the position of the pressing portion 521 according to the structure of the busbar body 1. In this embodiment, the abutting and pressing position of the busbar body 1 and the pressing member 52 is between the two pressing members 52, so the pressing portion 521 is arranged on the side of the pressing member 52 close to the first axis. When the driving member 53 is located at the first end, the busbar body 1 and the pressing member 52 are arranged at intervals; when the driving member 53 is located at the second end, the busbar body 1 and the pressing member 52 are in an abutting and pressing state.

[0039] Preferably, a pressure head 526 is provided on the side of the pressing member 52 close to the busbar body 1, and an elastic sleeve 527 is sleeved on the outside of the pressure head 526. When the busbar body 1 and the pressing member 52 in this embodiment are in abutment and compression, the pressure head 526 abuts and compresses the busbar body 1, and the pressure head 526 is the pressure-applying part of the pressing member 52 to the busbar body 1. The elastic sleeve 527 is made of elastic material, and the side of the elastic sleeve 527 close to the busbar body 1 is serrated, and the busbar body 1 is protected by the elastic sleeve 527.

[0040] In this embodiment, the driving member 53 can be stopped at any position of its motion trajectory by the friction between the mounting plate 51 and the driving member 53. In this embodiment, preferably: the locking mechanism also includes a self-locking component detachably connected to the mounting plate 51, the self-locking component includes a self-locking element detachably connected to the driving member 53, and the self-locking element includes a first state and a second state: when the self-locking element is in the first state, the pressing portion 521 and the busbar body 1 are pressed against each other, and the position of the driving member 53 relative to the mounting plate 51 is fixed; when the self-locking element is in the second state, the pressing portion 521 and the busbar body 1 are arranged at intervals, and the driving member 53 can slide relative to the mounting plate 51. In this embodiment, the self-locking element is detachably connected to the mounting plate 51 and detachably connected to the driving member 53. The self-locking element switches between a first state and a second state to control the position of the driving member 53 relative to the mounting plate 51, thereby controlling the position change between the pressing portion 521 and the busbar body 1. The position locking of the driving member 53 is achieved through the self-locking element, further achieving the self-locking function of the pressing portion 521 and the busbar body 1 being abutted and pressed.

[0041] In this solution, the self-locking element can be a linkage element or a separate element; when the self-locking element adopts a separate element, the self-locking element can adopt a limit rod, and the mounting plate 51 is provided with a first limit hole at a position corresponding to the first end and the second end of the driving element 53, and the driving element 53 is also provided with a second limit hole. When the driving element moves to the first end or the second end, the first limit hole and the second limit hole are correspondingly arranged, and the limit rod is inserted into the first limit hole and the second limit hole, so as to realize the locking of the driving element 53. However, the disadvantage of this technical solution is that it is necessary to manually judge whether the first limit hole and the second limit hole are corresponding.

[0042] Further optimized solution, the self-locking element includes a first protrusion 54 and a second protrusion 55, the first protrusion 54 is detachably connected to the side of the driving member 53 close to the pressing member 52, the first protrusion 54 includes a first contact surface 541 and a first sliding surface 542 arranged in sequence from the first end to the second end, and the distance between the first sliding surface 542 and the driving member 53 gradually decreases from the first end to the second end. The second protrusion 55 is slidably connected to the mounting plate 51, and the sliding direction of the second protrusion 55 and the mounting plate 51 is parallel to the rotation axis direction of the pressing member 52, the second protrusion 55 is arranged corresponding to the driving member 53, the second protrusion 55 includes a second sliding surface 551 and a second contact surface 552 arranged in sequence from the first end to the second end, and the distance between the second sliding surface 551 and the driving member 53 gradually decreases from the first end to the second end.

[0043] The self-locking component also includes a control member slidably connected to the driving member 53, and based on the abutment between the control member and the second protrusion 55, the position of the second protrusion 55 relative to the mounting plate 51 is controlled; when the self-locking element is in the first state, the first contact surface 541 and the second contact surface 552 are in contact with each other; when the self-locking element is in the second state, the first contact surface 541 and the second contact surface 552 are arranged at intervals, and the first sliding surface 542 is spaced apart or in sliding contact with the second sliding surface 551; the first state and the second state of the self-locking element are switched by the control member.

[0044] When the self-locking element switches from the first state to the second state, the control member abuts against the second protrusion 55 to control the position of the second protrusion 55 relative to the mounting plate 51, so that the second sliding surface 551 and the second contact surface 552 of the second protrusion 55 are all moved to the side of the mounting plate 51 away from the driving member 53. Without the restriction of the second protrusion 55, the driving member 53 moves along the motion trajectory, and the first contact surface 541 and the second contact surface 552 are arranged at intervals, and the first sliding surface 542 is spaced or slidingly contacted with the second sliding surface 551, to ensure that the driving member 53 can move along the motion trajectory. When the self-locking element switches from the second state to the first state, in the initial state, the first sliding surface 542 and the second sliding surface 551 are arranged opposite to each other, that is, the two are close to each other, the driving member 53 moves along the motion trajectory, the first sliding surface 542 and the second sliding surface 551 begin to contact each other, and the first sliding surface 542 applies a force perpendicular to the second sliding surface 551 to the second sliding surface 551. Since the second protrusion 55 is slidably connected with the mounting plate 51, and the sliding direction of the second protrusion 55 and the mounting plate 51 is parallel to the rotation axis direction of the clamping member 52, under this force, the second protrusion 55 begins to move to the side away from the driving member 53 until the self-locking element switches to the first state, that is, the first contact surface 541 and the second contact surface 552 are contact-connected, and the driving member 53 cannot move along the motion trajectory, thereby realizing the locking function of the driving member 53, and further realizing the self-locking function of the pressing portion 521 and the busbar body 1 being abutted and pressed.

[0045] A further optimized solution is that the control member includes a second sliding rod 561, and a third through hole is provided on the driving member 53 for the second sliding rod 561 to move, and the third through hole is arranged corresponding to the second protrusion; the second protrusion 55 is detachably connected to the third sliding rod 553 on the side away from the driving member 53, and the mounting plate 51 is detachably connected to the second shell 554 on the side away from the driving member 53, and the second shell 554 is provided with a third through hole for the third sliding rod 553 to slide, and the outer side of the second sliding rod 525 is sleeved with a second spring 555, and the two ends of the second spring 555 are detachably connected to the second shell 554 and the second protrusion 55 respectively.

[0046] The second protrusion 55 can only slide along a preset path under the action of the third sliding rod 553 and the fourth through hole, and the preset path direction is parallel to the rotation axis direction of the pressing member 52. Under the elastic action of the second spring 555, the second protrusion 55 extends out of the opening where it is located to between the mounting plate 51 and the driving member 53. When the self-locking element switches from the first state to the second state, the second sliding rod 561 is controlled to pass through the third through hole and abut against the second protrusion 55, and the position of the second protrusion 55 relative to the mounting plate 51 is controlled, so that the second sliding surface 551 and the second contact surface 552 of the second protrusion 55 are all moved to the side of the mounting plate 51 away from the driving member 53. Without the restriction of the second protrusion 55, the driving member 53 moves along the motion trajectory.

[0047] In a further optimized solution, the mounting plate 51 is detachably connected to a fixing plate 57, and the fixing plate 57 is slidably connected to the driving member 53. In this embodiment, the fixing plate 57 is slidably connected to the driving member 53, but the driving member 53 still moves along the first axis direction, and the driving member 53 and the pressing member 52 are wrapped by the fixing plate 57 and the mounting plate 51 to protect the internal components.

[0048] Preferably, the fixing plate 57 is provided with a first sliding hole along the first axial direction, and the driving member 53 includes a sliding portion 532 slidably connected to the first sliding hole; in the present embodiment, it is realized by the sliding connection between the first sliding hole and the sliding portion 532, and when working, the driving member 53 is moved along the first axial direction by the sliding portion 532 relative to the first sliding hole.

[0049] Preferably, the first sliding hole is a through hole structure, and the sliding part 532 is detachably connected to the driving plate 533 after passing through the first sliding hole. In this embodiment, the driving plate 533 drives the sliding part 532 relative to the first sliding hole, thereby realizing the movement of the driving member 53 along the first axis direction. In some embodiments, a mounting hole is provided on the driving plate 533, and the mounting hole and the third through hole are correspondingly arranged. A pressing plate 563 is slidably arranged in the mounting hole, and the pressing plate 563 is fixedly connected to the second sliding rod 561. The second sliding rod 561 is sleeved with a first spring 562 on the outside, and the two ends of the first spring 562 are detachably connected to the pressing plate 563 and the driving member 53, respectively. When the self-locking element switches from the first state to the second state, the pressing plate 563 is pressed to control the second sliding rod 561 to pass through the third through hole and abut against the second protrusion 55. When the state switching is completed, under the action of the first spring 562, the second sliding rod 561 moves between the pressing plate 563 and the driving member 53 to prevent the second sliding rod 561 from hindering the movement of the second protrusion 55.

Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
