[0041] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more, unless otherwise specifically defined.

[0042] As recorded in the background art, currently some display screens are formed by splicing a plurality of display screen bodies. In the related art, a locking rod is installed on one of the two display screen bodies, and a locking piece capable of restricting the movement of the locking rod is installed on the other display screen body. Adjacent two display screen bodies are connected through the cooperation of the locking rod and the locking piece. When connecting two display screen bodies, the operator not only needs to manually push the display screen body installed with the locking rod towards the display screen body installed with the locking piece, but also needs to manually push the locking rod towards the locking piece so that the locking piece restricts the movement of the locking rod. Although the above connection operation can connect two display screen bodies, the operation is cumbersome and laborious, which greatly limits the connection efficiency.

[0043] Refer to Figures 1 to 7, to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides a connecting mechanism for connecting a first component 400 and a second component 500; the connecting mechanism includes a first connecting portion 100, and the first connecting portion 100 includes a first mounting member 110, a first connecting member 120, and a driving member 130. Among them, the first mounting member 110 is used for mounting on the first component 400; the first connecting member 120 is mounted on the first mounting member 110, and the first connecting member 120 can be connected to the second component 500 by approaching the second component 500 along a first preset direction; the driving member 130 is mounted on the first mounting member 110, and the driving member 130 can rotate on the first mounting member 110 and can push the first connecting member 120 to approach the second component 500 along the first preset direction.

[0044] In the embodiment of the present application, the first component 400 and the second component 500 are usually both display bodies that can form an LED display screen. The structures of the first component 400 and the second component 500 are usually the same. In other embodiments, the first component 400 and the second component 500 can also be other components to be connected. Of course, the structures of the first component 400 and the second component 500 can also be different, which is determined according to actual needs and will not be limited here. The first mounting member 110 is usually fixedly mounted on the first component 400 by connecting screws to enhance the stability of the first mounting member 110 on the first component 400. To facilitate the manufacturing and processing of the connecting mechanism and to facilitate the connection between the first connecting member 120 and the second component 500, the length directions of the first connecting member 120 and the driving member 130 are both parallel to the first preset direction; the first connecting member 120 can be a locking rod. In this case, a locking piece or a locking block that can limit the movement of the locking rod is mounted on the second component 500; the driving member 130 can be a stud threadedly engaged with the first mounting member 110. Along with the rotation of the driving member 130 on the first mounting member 110, the driving member 130 can push the first connecting member 120 to approach the second component 500 along the first preset direction, so that the first connecting member 120 can be connected to the second component 500. In other embodiments, the connecting mechanism can also include a second connecting portion 200 for mounting on the second component 500. The first connecting member 120 can be connected to the second connecting portion 200 by approaching the second connecting portion 200 along the first preset direction to be connected to the second component 500; when the first connecting member 120 is a locking rod, the second connecting portion 200 is a locking piece or a locking block that can limit the movement of the locking rod.

[0045] When the first component 400 and the second component 500 are connected using the connecting mechanism of the present application, first, the first mounting member 110 is mounted on the first component 400, and then the driving member 130 is driven to rotate on the first mounting member 110; as the driving member 130 rotates, the driving member 130 will push the first connecting member 120 to approach the second component 500 along a first preset direction. During this process, the first connecting member 120 will be connected to the second component 500; since the first mounting member 110 is mounted on the first component 400 and the first connecting member 120 is mounted on the first mounting member 110, the first component 400 and the second component 500 will also be connected. When the driving member 130 of the present application is used to drive the first connecting member 120 to approach the second component 500 along the first preset direction, only the driving member 130 needs to be driven to rotate on the first mounting member 110, without manually pushing the first connecting member 120 to approach the second component 500 along the first preset direction. This operation method makes the connection operation convenient, fast and labor-saving, and greatly improves the connection efficiency.

[0046] Referring to Figures 1 to 7 , in an embodiment, the driving member 130 can rotate on the first mounting member 110 around its own axis. The axis of the driving member 130 is parallel to the first preset direction. The driving member 130 has a driving structure 1311 arranged along the first preset direction; a driving surface 1221 is formed on the surface of the first connecting member 120 close to the driving structure 1311. One end of the first connecting member 120 close to the driving structure 1311 is the first end, and the end of the first connecting member 120 far from the driving structure 1311 is the second end. The driving surface 1221 spirally extends along the axis of the driving member 130 from the first end to the second end; the driving structure 1311 is in contact with the driving surface 1221 to push the first connecting member 120 to approach the second component 500 along the first preset direction.

[0047] In this embodiment, the driving member 130 only rotates around its own axis on the first mounting member 110 and does not move along the first preset direction; the driving structure 1311 is usually a driving bar or a driving column. By adopting the driving structure 1311 and the driving surface 1221 used in cooperation in the present application, not only can the rotational motion of the driving member 130 be smoothly converted into the linear motion of the first connecting member 120, so that the first connecting member 120 can move slowly and smoothly, but also because the driving surface 1221 has a large contact area, the contact between the driving structure 1311 and the driving surface 1221 will become closer, thereby improving the transmission efficiency of the driving member 130. In addition, it is beneficial to simplify the structure. In addition, to improve the smoothness of the movement of the first connecting member 120, the number of the driving structures 1311 is two, the two driving structures 1311 are parallel and arranged at intervals, and the number of the driving surfaces 1221 is also two. The two driving structures 1311 are respectively arranged in one-to-one correspondence with the two driving surfaces 1221.

[0048] Referring to Figure 3 、 Figure 5 、 Figure 6 and Figure 8 In one embodiment, the first mounting member 110 has a first mounting space 111, and the first connecting member 120 is located within the first mounting space 111; a first limiting structure is provided on the inner wall surface of the first mounting space 111, and a second limiting structure is provided on the surface of the first connecting member 120. One of the first limiting structure and the second limiting structure is a limiting strip 112 arranged along a first preset direction, and the other is a limiting groove 1222 arranged along the first preset direction. The limiting strip 112 is inserted into the limiting groove 1222 and can slide within the limiting groove 1222 along the first preset direction.

[0049] In this embodiment, the first mounting space 111 is generally an installation cavity. The limiting strip 112 is fixedly installed on the inner wall surface of the first mounting space 111, and the limiting groove 1222 is provided on the surface of the first connecting member 120. The limiting strip 112 and the limiting groove 1222 are adapted to each other. In this case, the limiting strip 112 forms the first limiting structure, and the limiting groove 1222 forms the second limiting structure; in other embodiments, the limiting groove 1222 can also be provided on the inner wall surface of the first mounting space 111, and the limiting strip 112 is fixedly installed on the surface of the first connecting member 120. In this case, the limiting groove 1222 forms the first limiting structure, and the limiting strip 112 forms the second limiting structure. The limiting strip 112 and the limiting groove 1222 used in cooperation in this application not only provide limiting guidance for the movement of the first connecting member 120, ensure the smoothness and controllability of the movement of the first connecting member 120, but also effectively prevent the first connecting member 120 from separating from the first mounting member 110, enhancing the reliability of the first connecting portion 100. In addition, to strengthen the limiting guidance effect, the number of the limiting strips 112 is two, the two limiting strips 112 are parallel to each other and are spaced apart, and the number of the limiting grooves 1222 is also two, and the two limiting strips 112 are respectively arranged in one-to-one correspondence with the two limiting grooves 1222.

[0050] Referring to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 In one embodiment, the driving member 130 includes a driving body 131 and a driving sleeve 132. The driving body 131 is located within the first mounting space 111, and a driving structure 1311 is installed on the driving body 131; the driving sleeve 132 has an accommodating space, the first mounting member 110 is located within the accommodating space, and the driving sleeve 132 is connected to the driving body 131.

[0051] In this embodiment, the driving body 131 is usually a driving table or a driving column. The driving structure 1311 is usually fixedly installed on the surface of the driving body 131 and is an integrally formed structure with the driving body 131; the accommodating space is usually an accommodating cavity. The provided driving body 131 serves to install and carry the driving structure 1311; the provided driving sleeve 132 serves to facilitate the operator's grasping and operation; the provided accommodating space not only serves to protect the first mounting member 110, but also serves to reduce the first connecting portion 100.

[0052] Referring to Figure 3 and Figure 5 , in an embodiment, the driving sleeve 132 and the driving body 131 are connected by a fastener 133. In this embodiment, the fastener 133 is a fastening screw. The driving sleeve 132 is provided with a connection hole for the fastening screw to pass through. The diameter of the connection hole is smaller than the diameter of the nut on the fastening screw. The driving body 131 is provided with a threaded hole communicating with the connection hole. The fastening screw passes through the connection hole and then passes into the threaded hole, and is in threaded engagement with the hole wall of the threaded hole, so as to connect the driving sleeve 132 and the driving body 131.

[0053] Referring to Figure 3 , Figure 5 , Figure 9 and Figure 10 , in an embodiment, the driving sleeve 132 is provided with a first transmission structure, and the driving body 131 is provided with a second transmission structure. One of the first transmission structure and the second transmission structure is a transmission convex portion 134, and the other is a transmission concave portion 1312. The transmission convex portion 134 is inserted into the transmission concave portion 1312 and is adapted to the transmission concave portion 1312 to transmit the power of the driving sleeve 132 to the driving body 131.

[0054] In this embodiment, the driving convex part 134 is generally a driving convex column with an edge, such as a U-shaped convex column, a hexagonal convex column or a cuboid convex column. The driving convex part 134 is fixedly installed on the bottom wall of the accommodating space and extends towards the driving body 131. The connecting hole is arranged on the driving convex part 134. The driving concave part 1312 is generally a driving groove adapted to the driving convex column. The driving groove is arranged on the surface of the driving body 131 close to the bottom wall of the first installation space 111. The threaded hole is arranged at the bottom of the driving groove. The driving convex part 134 forms a first driving structure, and the driving concave part 1312 forms a second driving structure. To enable the driving convex part 134 to pass through the driving concave part 1312, the first installation part 110 is provided with a through hole for the driving convex part 134 to pass through. The driving convex part 134 and the driving concave part 1312 used in cooperation in this application can not only keep the driving body 131 and the driving sleeve 132 relatively stationary, avoid relative sliding between the driving sleeve 132 and the driving body 131, so as to ensure that the driving sleeve 132 can stably conduct power to the driving body 131, thereby enhancing the transmission efficiency and reliability. At the same time, the design in which the driving convex part 134 is adapted to the driving concave part 1312 can also enable the driving sleeve 132 to conduct the transmission force more evenly to the driving body 131, thereby reducing the occurrence of local stress concentration on the driving body 131 and prolonging the service life of the driving part 130. In other embodiments, the driving concave part 1312 can also be arranged on the driving sleeve 132, the driving convex part 134 is installed on the driving body 131, the driving concave part 1312 forms a first driving structure, and the driving convex part 134 forms a second driving structure.

[0055] Referring to Figure 3 , Figure 5 , Figure 9 and Figure 11 , in one embodiment, the accommodating space has a bottom wall. The surface of the first installation part 110 close to the bottom wall is the bottom surface. One of the bottom wall and the bottom surface is provided with an installation groove 1321, and the other is provided with an annular groove 113. The annular groove 113 is arranged around the axis of the driving part 130. A ball 135 is embedded in the installation groove 1321. The ball 135 can not only roll in the installation groove 1321, but also roll in the annular groove 113 along the circumferential direction of the annular groove 113.

[0056] In this embodiment, the shape of the installation groove 1321 is generally hemispherical. The installation groove 1321 is provided on the bottom wall, and the longitudinal section of the annular groove 113 is generally semicircular. The annular groove 113 is provided on the bottom surface. The cooperating ball 135, installation groove 1321 and annular groove 113 in this application transform the direct contact between the bottom wall and the bottom surface into rolling contact, which not only reduces the friction between the bottom wall and the bottom surface, thereby improving the smoothness of the rotation of the driving member 130 on the first mounting member 110, but also plays a role in vibration reduction and noise reduction. In addition, the number of balls 135 can be multiple. The multiple balls 135 are arranged at intervals around the axis of the driving member 130. The number of installation grooves 1321 is the same as the number of balls 135. The multiple balls 135 are respectively arranged in one-to-one correspondence with the multiple installation grooves 1321. In other embodiments, the installation groove 1321 can also be provided on the bottom surface, and the annular groove 113 is provided on the bottom wall.

[0057] Referring to Figure 5 , Figure 6 , Figure 12 and Figure 13 , in one embodiment, the connecting mechanism further includes a limiting portion 300. The limiting portion 300 includes a mounting structure 310, a ratchet wheel 320 and a pawl 330. The mounting structure 310 is mounted on the first mounting member 110 and can rotate circumferentially along the first connecting member 120; the ratchet wheel 320 is mounted on the surface of the first connecting member 120 along the circumferential direction of the first connecting member 120; the pawl 330 is mounted on the mounting structure 310 and can be kept engaged with the ratchet wheel 320; when the first connecting portion 100 is connected to the second component 500, the ratchet wheel 320 and the pawl 330 are kept engaged to limit the first connecting member 120 from moving along the first preset direction.

[0058] In this embodiment, the ratchet wheel 320 is fixedly mounted on the surface of the first connecting member 120; after the first connecting member 120 is connected to the second component 500, the operator only needs to drive the mounting structure 310 to rotate on the first connecting member 120 along the circumferential direction of the first connecting member 120, so that the pawl 330 can be engaged with the ratchet wheel 320, thereby limiting the first connecting member 120 from moving along the first preset direction. The cooperating ratchet wheel 320 and pawl 330 in this application play a limiting role, enhancing the reliability and stability of the connection between the first connecting portion 100 and the second component 500, and at the same time improving the convenience of operation; the provided mounting structure 310 plays a role in mounting and carrying the pawl 330.

[0059] Referring to Figure 5 and Figure 13 , in one embodiment, an adjusting torsion spring 340 is mounted on the mounting structure 310, and the pawl 330 can be separated from the ratchet wheel 320 through the adjusting torsion spring 340.

[0060] In this embodiment, the mounting structure 310 includes a mounting main board and a mounting cover. The mounting main board is sleeved on the first connecting member 120 and can rotate on the first connecting member 120 along the circumferential direction of the first connecting member 120. The mounting cover is arranged on the mounting main board, sleeved on the first connecting member 120, and can rotate on the first connecting member 120 along the circumferential direction of the first connecting member 120. The area between the mounting cover and the mounting main board forms an adjustment space. A partial structure of the pawl 330 is located in the adjustment space, and the adjusting torsion spring 340 is installed in the adjustment space. At the same time, a rotating shaft arranged along a first preset direction is installed on the mounting plate. The rotating shaft extends towards the adjustment space. A limiting hole is provided on the pawl 330, and the limiting hole is located between the ratchet wheel 320 and the rotating shaft. The adjusting torsion spring 340 includes a torsion spring body and two adjusting torsion arms. The torsion spring body is sleeved on the rotating shaft, and one of the two adjusting torsion arms is inserted into the limiting hole, and the other adjusting torsion arm is connected to the inner wall surface of the adjustment space. By adopting the adjusting torsion spring 340 in this application, the ratchet wheel 320 and the pawl 330 can be separated. In addition, in order to enable the mounting structure 310 to rotate smoothly on the first connecting member 120, a partial structure of the mounting structure 310 is located in the first mounting space 111. At the same time, the surface of the mounting structure 310 close to the second component 500 is in contact with the inner wall surface of the first mounting space 111, and the surface of the mounting structure 310 far from the second component 500 is in contact with the inner wall surface of the first mounting space 111 to limit the movement of the mounting structure 310 in the first mounting space 111 along the first preset direction.

[0061] Referring to Figure 3 、 Figure 5 、 Figure 6 and Figure 13 In an embodiment, the first connecting member 120 has a first limiting surface 1223. The surface of the mounting structure 310 close to the first limiting surface 1223 is the second limiting surface. A first return spring 140 is arranged between the first limiting surface 1223 and the second limiting surface. The first end of the first return spring 140 is in contact with the first limiting surface 1223, and the second end of the first return spring 140 is in contact with the second limiting surface. The first end of the first return spring 140 and the second end of the first return spring 140 are arranged oppositely. When the first connecting member 120 is connected to the second component 500, the first return spring 140 is in a compressed state.

[0062] In this embodiment, the first connecting member 120 includes a connecting portion 121 and a mating portion 122. Among them, the mating portion 122 is located on the side of the connecting portion 121 away from the second component 500, and a driving surface 1221 is provided on the mating portion 122; the first return spring 140 is sleeved on the connecting portion 121. The first end of the first return spring 140 contacts the surface of the mating portion 122 close to the connecting portion 121, and the surface of the mating portion 122 close to the connecting portion 121 is formed as a first limiting surface 1223. During the process of the first connecting member 120 moving towards the second component 500 along the first preset direction, the first return spring 140 will be gradually compressed until the first connecting member 120 and the second component 500 are connected, and then the first return spring 140 will stop compressing. At this time, the first return spring 140 will apply a thrust to the first connecting member 120 towards the driving member 130; at the moment when the first connecting member 120 and the second component 500 are separated, the first connecting member 120 will be reset under the action of the thrust applied by the first return spring 140. The provided first return spring 140 can not only provide a reset force for the first connecting member 120 to ensure that the first connecting member 120 can be reset, but also effectively absorb the impact force generated when the first connecting member 120 and the second component 500 are connected, playing a buffering role.

[0063] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 14 and Figure 15 , in an embodiment, the connecting mechanism further includes a second connecting portion 200. The second connecting portion 200 can be connected to the first connecting portion 100; the second connecting portion 200 includes a second mounting member 210 and a second connecting member 220. The second mounting member 210 is used for mounting on the second component 500; the second connecting member 220 is mounted on the second mounting member 210. A connecting through hole 221 is provided on the second connecting member 220. The connecting through hole 221 includes a through hole section 2211 and a limiting hole section 2212 that are communicated with each other. The direction from the limiting hole section 2212 to the through hole section 2211 is the second preset direction. There is an included angle between the second preset direction and the first preset direction. The second connecting member 220 can slide on the second mounting member 210 along the second preset direction; the first connecting member 120 has a connecting head 123. The connecting head 123 can pass through the through hole section 2211, and the limiting hole section 2212 can prevent the connecting head 123 from passing through; when the first connecting portion 100 and the second connecting portion 200 are connected, the connecting head 123 is located on the side of the limiting hole section 2212 away from the driving member 130 and is blocked by the limiting hole section 2212 from moving towards the driving member 130.

[0064] In this embodiment, the second mounting member 210 is usually fixedly mounted on the second component 500 by connecting screws to enhance the stability of the second mounting member 210 on the second component 500; the second preset direction is usually perpendicular to the first preset direction, and at the same time, the second preset direction has only one direction, which is the direction from the limiting hole section 2212 to the through-hole section 2211. In other embodiments, the included angle between the second preset direction and the first preset direction can also be an acute angle. The connecting head 123 is located at one end of the first connecting member 120 away from the driving member 130; the aperture of the through-hole section 2211 is larger than the maximum diameter of the connecting head 123, so that the connecting head 123 can pass through the through-hole section 2211, and the aperture of the limiting hole section 2212 is smaller than the maximum diameter of the connecting head 123, so that the limiting hole section 2212 can prevent the connecting head 123 from passing through.

[0065] When the first connecting portion 100 and the second connecting portion 200 are connected, first, the driving member 130 is rotated to move the first connecting member 120 toward the second connecting portion 200. During this process, the second connecting member 220 is driven to slide on the second mounting member 210 in a direction opposite to the second preset direction, so that the connecting head 123 passes through the through-hole section 2211; after the connecting head 123 passes through the through-hole section 2211, the second connecting member 220 is driven to slide on the second mounting member 210 in the second preset direction, so that the connecting head 123 is blocked by the limiting hole section 2212 from moving toward the driving member 130. At this time, the first connecting member 120 and the second connecting member 220 will be connected, and the first connecting portion 100 and the second connecting portion 200 will also be connected. By using the first connecting member 120 and the second connecting member 220 used in cooperation in this application, the first connecting portion 100 and the second connecting portion 200 can be connected and separated, so that the first component 400 and the second component 500 can be connected and separated.

[0066] Refer to Figure 15 , in one embodiment, the second connecting portion 200 further includes a second return spring 230. The second return spring 230 is mounted on the second mounting member 210 and can apply a thrust along the second preset direction to the second connecting member 220.

[0067] In this embodiment, the second mounting member 210 has a second mounting space. A partial structure of the second connecting member 220 is located in the second mounting space. The second return spring 230 is mounted in the second mounting space. The second mounting member 210 is provided with a through hole communicating with the connecting through hole 221. When the first connecting portion 100 and the second connecting portion 200 are connected, first, the first connecting member 120 is moved toward the second connecting portion 200 by rotating the driving member 130. During this process, the connecting head 123 will push the second connecting member 220 to slide on the second mounting member 210 in a direction opposite to the second preset direction to overcome the thrust exerted by the second return spring 230 until the connecting head 123 can pass through the corresponding through hole section 2211. After the connecting head 123 passes through the through hole section 2211, the second connecting member 220 is released. The second connecting member 220 will then slide on the second mounting member 210 in the second preset direction under the action of the thrust exerted by the second return spring 230 until the connecting head 123 is blocked by the limiting hole section 2212 from moving toward the driving member 130. At this time, the first connecting member 120 and the second connecting member 220 will be connected, and the first connecting portion 100 and the second connecting portion 200 will also be connected.

[0068] Referring to Figure 3 , Figure 6 and Figure 13 , in one embodiment, the first connecting member 120 is provided with a limiting groove 1211. The limiting groove 1211 includes a guiding groove section 1211a and a limiting groove section 1211b. Among them, the guiding groove section 1211a is arranged along the first preset direction. The limiting groove section 1211b is located on the side of the guiding groove section 1211a close to the driving structure 1311 and communicates with the guiding groove section 1211a. The limiting groove section 1211b spirally extends along the axis of the driving member 130 from the first end to the second end. The limiting portion 300 further includes a limiting member 350. The limiting member 350 is mounted on the mounting structure 310 and can slide in the limiting groove 1211. When the first connecting portion 100 is connected to the second connecting portion 200, the limiting member 350 is located in the limiting groove section 1211b and can block the first connecting member 120 from moving away from the driving structure 1311.

[0069] In this embodiment, the limiting groove 1211 is provided on the surface of the first connecting member 120; the limiting member 350 is generally a limiting post or a limiting pin, and the limiting member 350 is always located within the limiting groove 1211 and can slide within the limiting groove 1211 following the movement of the first connecting member 120; when the first connecting member 120 is connected to the second connecting member 220, the limiting member 350 remains in contact with the groove wall of the limiting groove section 1211b away from the second connecting portion 200. The limiting member 350 and the limiting groove section 1211b used in cooperation in this application can drive the first connecting member 120 that has been connected to the second connecting member 220 to move a certain distance towards the driving member 130, thereby making the connection between the first connecting member 120 and the second connecting member 220 more stable.

[0070] Referring to Figures 1 to 15 , according to another aspect of the present application, an embodiment of the present application further provides a display screen, which includes a screen body portion and the above-mentioned connecting mechanism. The screen body portion includes a first screen body and a second screen body. The first connecting portion 100 is installed on the first screen body. The first connecting member 120 can be connected to the second screen body by approaching the second screen body along a first preset direction. The first screen body forms a first component 400, and the second screen body forms a second component 500.

[0071] In the embodiment of the present application, the structures of the first screen body and the second screen body are generally the same. In other embodiments, the structures of the first screen body and the second screen body may also be different, which is determined according to actual requirements and will not be limited here; the first mounting member 110 is generally fixedly installed on the first screen body using connecting screws to enhance the stability of the first mounting member 110 on the first screen body; in other embodiments, the connecting mechanism further includes a second connecting portion 200, and the second connecting portion 200 is installed on the second screen body. The second connecting portion 200 is also generally fixedly installed on the second screen body using connecting screws to enhance the stability of the second connecting portion 200 on the second screen body. In addition, both the first connecting portion 100 and the second connecting portion 200 are generally installed on the first screen body or the second screen body to facilitate the connection between the first screen body and the second screen body.

[0072] In summary, implementing the connecting mechanism and the display screen provided in this embodiment has at least the following beneficial technical effects: When using the connecting mechanism of the present application to connect the first component 400 and the second component 500, first install the first mounting member 110 on the first component 400, and then drive the driving member 130 to rotate on the first mounting member 110; along with the rotation of the driving member 130, the driving member 130 will push the first connecting member 120 to approach the second component 500 along a first preset direction. During this process, the first connecting member 120 will be connected to the second component 500; since the first mounting member 110 is installed on the first component 400 and the first connecting member 120 is installed on the first mounting member 110, the first component 400 and the second component 500 will also be connected. When using the driving member 130 in the present application to drive the first connecting member 120 to approach the second component 500 along the first preset direction, it is only necessary to drive the driving member 130 to rotate on the first mounting member 110, without manually pushing the first connecting member 120 to approach the second component 500 along the first preset direction. This operation method makes the connection operation convenient, fast and labor-saving, and greatly improves the connection efficiency.

[0073] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
