Description

Technical Field

[0001] This application relates to the field of display screen technology, and more particularly to a connection tool. Background Technology

[0002] Currently, when a larger screen is needed, one solution is to splice multiple smaller screens together to form a larger screen. A common splicing method involves connecting adjacent screens using a cascade board and connecting pieces.

[0003] However, the existing method of connecting cascade boards and connecting plates involves multiple connecting pins on the cascade board and multiple pin holes on the connecting plate to cooperate with the connecting pins. During connection, multiple connecting pins need to be manually pressed into the pin holes one by one to complete the connection between the connecting pins and the pin holes, which is time-consuming, labor-intensive, and very inefficient. Utility Model Content

[0004] In view of the above problems, this application proposes an embodiment. The purpose of this application embodiment is to provide a connection tool that can connect multiple connecting pins to pin holes at one time, so as to solve the above problems.

[0005] To achieve this objective, the embodiments of this application provide the following technical solutions:

[0006] This application provides a connection tool, including:

[0007] The first component includes a first main body plate, a connecting post, and a handle. The first main body plate has multiple through holes, and a connecting post can be movably passed through each of the through holes. The handle is rotatably disposed on one side of the first main body plate and is drivenly connected to the connecting post.

[0008] The second component includes a second main body plate and a locking member. The second main body plate is provided with connecting holes at positions corresponding to the connecting posts. The locking member is movably connected to the second main body plate.

[0009] Wherein, after the first component and the second component are aligned, the end of the connecting post away from the handle passes through the corresponding connecting hole, and the position of the connecting post is locked by the locking member. The handle is rotated from the first position to the second position to drive the connecting post to move relative to the first main body plate along its axial direction, so as to reduce the distance between the first main body plate and the second main body plate.

[0010] Optionally, the end of the connecting post away from the handle includes a snap-fit ​​section and a snap-fit ​​connector, wherein the diameter of the snap-fit ​​section is smaller than the diameter of the connecting post;

[0011] The locking component includes a locking plate and a spring component. The locking plate has locking holes at positions corresponding to the plurality of connecting holes. Each locking hole includes an unlocking section and a locking section. The diameter of the unlocking section matches the diameter of the connecting post, and the diameter of the locking section matches the diameter of the locking section.

[0012] When the card plate is in the third position, the spring is compressed, the unlocking section corresponds to the connecting hole, and the connecting post passes through the connecting hole into or out of the unlocking section;

[0013] When the card plate is in the fourth position, under the elastic force of the spring, the locking section corresponds to the connecting hole and is connected to the snap-fit ​​section.

[0014] Optionally, the second main body plate has a receiving groove and a cover plate on the side facing away from the first main body plate;

[0015] The card plate is movably disposed within the receiving groove, and the card plate is provided with an operating part, which is disposed outside the receiving groove;

[0016] The cover plate is connected to the second main plate and covers the receiving groove. The cover plate has a through hole at the position corresponding to the connection hole.

The adapter shaft passes through the second mounting hole, the first mounting hole and the connecting elongated hole to realize the connection between the fixing frame, the connecting plate and the handle.

[0020] When the handle rotates from the first position to the second position, the cam structure presses against the first main plate, causing the adapter shaft to move along the extension direction of the connecting hole, thereby moving the connecting plate and the connecting column through the adapter shaft.

[0021] Optionally, the fixing frame includes a base plate and a pair of connecting ears located on opposite sides of the base plate. The base plate and the pair of connecting ears form a U-shaped structure. The base plate is connected to the first main body plate. The pair of connecting ears are respectively provided with the connecting elongated holes. The connecting plates are respectively provided on both sides of the pair of connecting ears.

[0022] One end of the handle is provided with three connecting arms, each of which is provided with the cam structure. The connecting arm located in the middle position is disposed within the U-shaped structure, and the connecting arms located on the two sides are respectively disposed on the side of the connecting plate facing away from the connecting ear.

[0023] Optionally, there are multiple pairs of connecting ears, which are spaced apart along the length of the base plate, and each pair of connecting ears is connected to a handle.

[0024] The connecting plate is a long strip structure. Along the length of the base plate, the connecting plate can span multiple pairs of connecting ears and is connected to multiple connecting ears. Each connecting plate is provided with multiple connecting posts.

[0025] Optionally, the fixing frame and / or the first main body plate are provided with a limiting protrusion. When the handle is rotated to the second position, the handle is connected to the limiting protrusion to limit the handle from continuing to rotate.

[0028] Optionally, the first main body plate is provided with a plurality of limiting posts on the side facing the second main body plate;

[0029] The second main plate has multiple limiting grooves on the side facing the first main plate, which correspond to the positions of the multiple limiting posts;

[0030] After the first component and the second component are aligned, the limiting post extends into the limiting groove corresponding to it.

[0031] Alternatively, the second main body plate may be provided with a handle.

[0032] The technical solution provided in this application embodiment, by pressing the connecting piece and the cascade plate with the first component and the second component, can connect multiple connecting pins on the cascade plate to multiple pin holes on the connecting piece in one go, avoiding connecting them one by one, avoiding complicated and time-consuming operations, so as to quickly complete the connection between the connecting piece and the cascade plate, saving effort and effectively improving efficiency, and has the characteristics of stable structure, simple operation and strong practicality.

[0050] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0051] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0053] Figure 1This is a schematic diagram of the planar structure of the connecting tool provided in the embodiments of this application, as shown below. Figure 1 As shown.

[0054] This application provides a connection tool, including a first component 100 and a second component 200 that cooperate with each other. See also Figure 1 and Figure 2 The first component 100 includes a first main plate 10, a connecting post 11 and a handle 12. The first main plate 10 is provided with a plurality of through holes 101, and a connecting post 11 is movably inserted through each through hole 101. The handle 12 is rotatably disposed on one side of the first main plate 10 and is drivenly connected to the connecting post 11.

[0055] See Figure 2 and Figure 3 The second component 200 includes a second main plate 20 and a locking member 21. The second main plate 20 is provided with connecting holes 201 at positions corresponding to the connecting post 11. The locking member 21 is movably connected to the second main plate 20.

[0056] Among them, see Figures 1 to 3 After the first component 100 and the second component 200 are aligned, the end of the connecting post 11 away from the handle 12 passes through the corresponding connecting hole 201, and the position of the connecting post 11 is locked by the locking member 21. The handle 12 rotates from the first position to the second position, so as to drive the connecting post 11 to move relative to the first main body plate 10 along its axial direction, thereby reducing the distance between the first main body plate 10 and the second main body plate 20. In this embodiment, the direction of rotation of the handle 12 from the first position to the second position can be set according to different needs, such as... Figure 1 Taking the middle position as an example, the direction in which the handle 12 rotates from the first position to the second position can be clockwise or counterclockwise.

[0057] When the handle 12 is in the first position, it can be in a vertical position, or an upward-raised position. When rotated to the second position, as... Figure 1 As shown, the handle 12 is in a horizontal state, or a pressed-down state. Of course, in some embodiments, the handle 12 may also be in a horizontal state when in the first position, and in a vertical state when rotated to the second position.

[0058] Taking the handle 12 in the first position, where the handle 12 is in a vertical state, as an example, when using it, first adjust the handle 12 to a vertical state and adjust the locking member 21 to an unlocked state. At this time, the first component 100 and the second component 200 can be aligned, the connecting post 11 extends into and passes through the corresponding connecting hole 201, and then the position of the connecting post 11 is locked by the locking member 21. At this time, the distance between the first main body plate 10 and the second main body plate 20 is relatively large.

[0059] Rotating handle 12 from the first position to the second position, i.e., from the vertical state to the downward pressing state, causes handle 12 to move connecting post 11 relative to the first main body plate 10 along its axial direction. Figure 1 Taking the middle position as an example, the handle 12 drives the connecting column 11 to move upward. Since the connecting column 11 is locked by the locking member 21, the connecting column 11 can drive the second component 200 to move upward relative to the first main body plate 10 through the locking member 21, thereby reducing the distance between the first main body plate 10 and the second main body plate 20.

[0060] See Figure 4 and Figure 5 The connection tools provided in this application include, but are not limited to, those that can be used to connect the cascade board 300 and the connecting piece 400. The cascade board 300, in conjunction with the connecting piece 400, can splice two adjacent screens 500. The existing method of connecting the cascade board 300 and the connecting piece 400 involves the cascade board 300 having multiple connecting pins 301 and the connecting piece 400 having multiple pin holes that mate with the connecting pins 301. During connection, the multiple connecting pins 301 need to be manually pressed into the pin holes one by one to complete the connection between the connecting pins 301 and the pin holes, which is time-consuming, labor-intensive, and very inefficient.

[0061] By using the connection tool provided in this application embodiment, firstly, the plurality of connecting pins 301 on the cascade plate 300 are aligned with the plurality of pin holes on the connecting piece 400. Then, the first component 100 and the second component 200 of the connection tool are distributed on both sides of the cascade plate 300 and the connecting piece 400 and accurately aligned. The connecting post 11 of the first component 100 is passed through the cascade plate 300 and the connecting piece 400 (both the cascade plate 300 and the connecting piece 400 have holes for the connecting post 11 to pass through), extends into and passes through the connecting hole 201 on the corresponding second component 200, and then the position of the connecting post 11 is locked by the locking member 21.

[0062] Rotate the handle 12 from the first position to the second position, that is, from the vertical state to the pressed state. At this time, the handle 12 drives the connecting column 11 to move relative to the first main plate 10 along its axial direction. When the connecting column 11 moves, it can drive the second component 200 to move relative to the first main plate 10 in the direction closer to the first main plate 10, thereby reducing the distance between the first main plate 10 and the second main plate 20. During the process of shortening the distance between the first main plate 10 and the second main plate 20, the first main plate 10 and the second main plate 20 respectively squeeze the cascade plate 300 and the connecting piece 400, thereby shortening the distance between the cascade plate 300 and the connecting piece 400. This allows multiple connecting pins 301 on the cascade plate 300 to connect with multiple pin holes on the connecting piece 400 in one go, avoiding the need for connecting one by one. This avoids complicated and time-consuming operations, and quickly completes the connection between the connecting piece 400 and the cascade plate 300. It saves effort and effectively improves efficiency, and has the characteristics of stable structure, simple operation, and strong practicality.

[0063] After the cascade plate 300 and connecting piece 400 are connected, the handle 12 can be rotated from the second position to the first position, that is, from the pressed-down state to the vertical state. At this time, the handle 12 drives the connecting post 11 to move relative to the first main plate 10 along its axial direction. When the connecting post 11 moves, it can drive the second component 200 to move away from the first main plate 10 relative to the first main plate 10, thereby increasing the distance between the first main plate 10 and the second main plate 20. At this time, the locking member 21 can be adjusted to the unlocked state, and the connecting post 11 of the first component 100 can be pulled out of the connecting hole 201 on the corresponding second component 200, as well as the cascade plate 300 and connecting piece 400, to complete the separation of the first component 100 and the second component 200. Then, the cascade plate 300 and connecting piece 400 in other areas can be connected.

[0064] The technical solutions provided in the embodiments of this application will be described in further detail below.

[0065] Combination Figures 1 to 3 See Figure 6 and Figure 7 In one embodiment of this application, the connecting post 11 and the locking member 21 are implemented such that the end of the connecting post 11 away from the handle 12 includes a snap-fit ​​section 111 and a snap-fit ​​connector 112, and the diameter of the snap-fit ​​section 111 is smaller than the diameter of the connecting post 11.

[0066] The locking component 21 includes a locking plate 211 and a spring component 212. The locking plate 211 has locking holes 2111 at positions corresponding to the multiple connecting holes 201. Each locking hole 2111 includes an unlocking section and a locking section. The diameter of the unlocking section matches the diameter of the connecting post 11, and the diameter of the locking section matches the diameter of the locking section 211. The unlocking section and the locking section form a gourd-like structure.

[0067] The position of the locking plate 211 relative to the second main plate 20 can be changed. When the locking plate 211 is in the third position, the spring member 212 is compressed, the unlocking section corresponds to the connecting hole 201, and the connecting post 11 passes through the connecting hole 201 into or out of the unlocking section. When the locking plate 211 is in the fourth position, under the elastic force of the spring member 212, the locking section corresponds to the connecting hole 201 and is connected to the locking section 111.

[0068] The movement mode of the card plate 211 can be set according to different needs, for example, by... Figure 7 Taking the orientation as an example, if the unlocking and locking sections of the latching hole 2111 are set along the left-right direction (the width direction of the second main body plate 20), then the movement of the latch plate 211 is in the left-right direction. Figure 7 As shown, at this time, the locking plate 211 is in the fourth position, the spring member 212 pushes the locking plate 211 to move to the left, the locking hole 2111 is connected to the locking section 111 of the connecting post 11 through the locking section, the locking member 21 is in the locked state, thereby locking the position of the connecting post 11.

[0069] When the locking plate 211 is pushed to the right, the locking plate 211 moves from the fourth position to the third position, the spring 212 is compressed, the unlocking section of the locking hole 2111 corresponds to the connecting hole 201, the locking member 21 is in the unlocked state, and the connecting post 11 can pass into or out of the unlocking section.

[0070] For example, if the unlocking and locking sections of the snap-fit ​​hole 2111 are set along the front-back direction (the length direction of the second main body plate 20), then the movement of the snap-fit ​​plate 211 is in the front-back direction. The switching between the locking and unlocking states of the locking member 21 is similar to the above, and will not be repeated here.

[0071] See also Figure 7To protect the locking element 21 and prevent interference from other external components, in some feasible embodiments of this application, the second main body plate 20 has a receiving groove 202 and a cover plate 203 on the side facing away from the first main body plate 10. A locking plate 211 is movably disposed within the receiving groove 202, and an operating part 2112 is provided on the locking plate 211, located outside the receiving groove 202. The cover plate 203 is connected to the second main body plate 20 and covers the receiving groove 202, with a through hole 2031 at the position corresponding to the connecting hole 201. The cover plate 203 and the receiving groove 202 form a relatively enclosed space, within which the locking plate 211 can move, preventing contact with other external components and effectively protecting the locking element 21. The connecting post 11 can extend out of the receiving groove 202 through the hole 2031.

[0072] The operating part 2112 is located outside the receiving groove 202, allowing the user to easily adjust the position of the latch plate 211 to adjust the state of the locking member 21. When the unlocking and locking sections of the latching hole 2111 are positioned in the left-right direction, the operating part 2112 can be pressed to adjust the position of the latch plate 211. When the unlocking and locking sections of the latching hole 2111 are positioned in the front-back direction, the operating part 2112 can be slid to adjust the position of the latch plate 211.

[0073] See also Figure 6 To facilitate the insertion of the connecting post 11 into the connecting hole 201, in some embodiments of this application, the side of the snap-fit ​​connector 112 away from the first main body plate 10 is a tapered structure. The inclined surface of the tapered structure has a guiding effect. When the snap-fit ​​connector 112 contacts the edge of the connecting hole 201, the tapered structure guides it, making it easier for the snap-fit ​​connector 112 to enter the connecting hole 201. Furthermore, the tapered structure is provided with a shrinkage groove 113. When the snap-fit ​​connector 112 is inserted into the connecting hole 201, the shrinkage groove 113 allows the snap-fit ​​connector 112 to shrink and become smaller, so that the snap-fit ​​connector 112 can be inserted into the connecting hole 201 more smoothly. The shrinkage groove 113 includes, but is not limited to, a straight line shape, a cross shape, etc.

[0074] Combination Figure 2 and Figure 3 See Figure 8In this embodiment, one way the handle 12 and the connecting post 11 are connected is as follows: a fixing frame 14 is fixedly connected to the side of the first main body plate 10 facing away from the second main body plate 20. The fixing frame 14 has a connecting elongated hole 141, which extends along the axial direction of the connecting post 11. One end of the connecting post 11 has a connecting plate 15, which has a first mounting hole. One end of the handle 12 has a cam structure 121, which has a second mounting hole. A transition shaft 16 passes through the second mounting hole, the first mounting hole, and the connecting elongated hole 141 to achieve the connection between the fixing frame 14, the connecting plate 15, and the handle 12. When the handle 12 rotates from the first position to the second position, the cam structure 121 presses against the first main body plate 10, causing the transition shaft 16 to move along the extension direction of the connecting elongated hole 141, thereby moving the connecting plate 15 and the connecting post 11.

[0075] The fixing frame 14 is, but is not limited to, fixedly connected to the first main body plate 10 by fasteners such as screws. The connecting elongated hole 141 on the fixing frame 14 can provide clearance for the movement of the connecting column 11. The connecting column 11 and the connecting plate 15 can be integrally formed or separate structures. When the connecting column 11 and the connecting plate 15 are separate structures, one way to connect the connecting column 11 and the connecting plate 15 is that the connecting plate 15 is provided with a screw hole, one end of the connecting column 11 is provided with a thread, and the connecting column 11 and the connecting plate 15 are threadedly connected.

[0076] When using it, please refer to [link / reference]. Figure 8 When the handle 12 rotates from the first position to the second position, that is, from the vertical state to the downward pressing state, the first main body plate 10 is pressed by the cam structure 121. Based on the eccentric setting of the cam structure 121, the cam structure 121 can drive the adapter shaft 16 to move upward along the connecting elongated hole 141. When the connecting shaft moves, the connecting shaft drives the connecting plate 15 to move upward synchronously, and the connecting plate 15 drives the connecting post 11 to move upward synchronously. Since the connecting post 11 is locked by the locking plate 211 in the locking member 21, the connecting post 11 can drive the second component 200 to move upward relative to the first main body plate 10 through the locking member 21, thereby reducing the distance between the first main body plate 10 and the second main body plate 20, thereby completing the connection between the cascade plate 300 and the connecting piece 400.

[0077] After the cascade plate 300 and connecting piece 400 are connected, the handle 12 can be rotated from the second position to the first position, that is, from the pressed-down state to the vertical state. Based on the eccentric setting of the cam structure 121, the cam structure 121 can drive the adapter shaft 16 to move downward along the connecting elongated hole 141. When the connecting shaft moves, the connecting shaft drives the connecting plate 15 to move downward synchronously, and the connecting plate 15 drives the connecting post 11 to move downward synchronously, increasing the distance between the first main plate 10 and the second main plate 20. Then, the locking member 21 is adjusted to the unlocked state, thereby separating the first component 100 from the second component 200, so that the cascade plate 300 and connecting piece 400 in other areas can be connected again.

[0078] See also Figure 8 and Figure 9 In some feasible embodiments of this application, one possible implementation of the fixing frame 14 is that the fixing frame 14 includes a base plate 143 and a pair of connecting ears 144 located on opposite sides of the base plate 143. The base plate 143 and the pair of connecting ears 144 form a U-shaped structure. The base plate 143 is connected to the first main body plate 10. The pair of connecting ears 144 are respectively provided with connecting elongated holes 141, and connecting plates 15 are respectively provided on both sides of the pair of connecting ears 144. One possible implementation of the handle 12 is that one end of the handle 12 is provided with three connecting arms 122. Each connecting arm 122 is provided with a cam structure 121. The connecting arm 122 located in the middle position is disposed within the U-shaped structure, and the connecting arms 122 located on the sides are respectively disposed on the side of the connecting plate 15 facing away from the connecting ears 144.

[0079] This configuration allows the mounting bracket 14 to simultaneously support both connecting plates 15, while also enabling the handle 12 to apply force to both plates simultaneously and evenly, resulting in more synchronized movement of the two connecting plates 15. This synchronized movement of the two connecting plates 15 also synchronizes the movement of the connecting posts 11 connected to them, ensuring a uniform force applied by the connecting posts 11 to the second component 200. This prevents deviation in the movement of the second component 200 and ensures effective connection between the cascade plate 300 and the connecting piece 400.

[0080] Furthermore, in this embodiment, the number of handles 12 can be set according to different needs. There can be one handle 12 or multiple handles 12, as shown in [reference needed]. Figure 1 , Figure 2 , Figure 4 and Figure 8 In some feasible embodiments of this application, the number of handles 12 may be three, and the direction in which the handles 12 rotate from the first position to the second position may be the same or different, such as some handles 12 rotating clockwise and others rotating counterclockwise.

[0081] When there are multiple handles 12, one implementation of the fixing bracket 14 is as follows: (See...) Figure 8 and Figure 9 The mounting bracket 14 has a base plate 143 and multiple pairs of connecting ears 144. Specifically, the multiple pairs of connecting ears 144 are spaced apart along the length of the base plate 143, and each pair of connecting ears 144 is connected to a handle 12. The connecting plate 15 is a long strip structure that spans multiple pairs of connecting ears 144 along the length of the base plate 143 and is connected to multiple connecting ears 144. Each connecting plate 15 has multiple connecting posts 11. In this implementation, multiple handles 12 can be installed on one mounting bracket 14.

[0082] When there are multiple handles 12, another way to implement the fixing frame 14 is that there are multiple fixing frames 14, and each fixing frame 14 has a pair of connecting ears 144 on its base plate 143. The multiple fixing frames 14 are distributed at intervals along the length direction of the first main body plate 10, and each fixing frame 14 is connected to a handle 12. The connecting plate 15 is a long strip structure, which can span multiple fixing frames 14 and is connected to the connecting ears 144 on multiple fixing frames 14. Each connecting plate 15 is provided with multiple connecting posts 11.

[0083] When there are multiple handles 12, another implementation of the fixing frame 14 is that the fixing frame 14 has a base plate 143 that extends along the length of the first main body plate 10. The base plate 143 is provided with a pair of connecting ears 144. The pair of connecting ears 144 are provided with multiple connecting elongated holes 141 that are spaced apart along the length of the first main body plate 10. Each connecting elongated hole 141 is connected to a handle 12. The connecting plate 15 is a long strip structure. The connecting plate 15 extends in the same direction as the fixing frame 14 and is provided with a first mounting hole at the position corresponding to the connecting elongated hole 141.

[0084] See Figure 9 and Figure 10In some feasible embodiments of this application, a limiting protrusion 142 is provided on the fixing frame 14 and / or the first main body plate 10. When the handle 12 is rotated to the second position, the handle 12 is connected to the limiting protrusion 142 to limit the handle 12 from continuing to rotate. By setting the limiting protrusion 142, the rotation range of the handle 12 can be limited. For example, when the handle 12 is in the second position in a pressed state, after the handle 12 completes the pressed action, that is, when the handle 12 is in the second position, the limiting protrusion 142 can abut against the cam structure 121 on the handle 12, so that the handle 12 will no longer continue to press down. By limiting the rotation range of the handle 12 through the limiting protrusion 142, it can effectively avoid excessive force and disengagement of the connecting post 11 from the locking member 21. At the same time, it can also effectively prevent the distance between the first main body plate 10 and the second main body plate 20 from shortening too much, which would cause damage to the cascade plate 300 and the connecting piece 400. The limiting protrusion 142 can be provided on the fixing frame 14, such as on the base plate 143, or on the first main body plate 10. Of course, it is also possible to provide the limiting protrusion 142 on both the fixing frame 14 and the first main body plate 10.

[0085] See Figure 2 and Figure 3 In some feasible embodiments of this application, the first main body plate 10 has a plurality of first clamping protrusions 102 on the side facing the second main body plate 20; the second main body plate 20 has a plurality of second clamping protrusions 204 on the side facing the first main body plate 10. The first clamping protrusions 102 and the second clamping protrusions 204 increase the friction of the contact surfaces of the first main body plate 10 and the second main body plate 20, making the contact between the first main body plate 10 and the second main body plate 20 and the cascade plate 300 and the connecting piece 400 more stable. The first clamping protrusions 102 and the second clamping protrusions 204 are, but are not limited to, made of elastic material, thereby reducing damage to the cascade plate 300 and the connecting piece 400. Furthermore, the second clamping protrusions 204 located on the outer periphery of the connecting hole 201 have a guide slope 2041 on the side facing the connecting hole 201. The guide slope 2041 facilitates the insertion of the connecting post 11 into the connecting hole 201, improving operational efficiency.

[0086] See also Figure 2 and Figure 3 In some feasible embodiments of this application, the first main body plate 10 is provided with a plurality of limiting posts 103 on the side facing the second main body plate 20; the second main body plate 20 is provided with a plurality of limiting grooves 205 corresponding to the positions of the plurality of limiting posts 103 on the side facing the first main body plate 10; after the first component 100 and the second component 200 are aligned, the limiting posts 103 extend into the corresponding limiting grooves 205. Through the cooperation between the limiting posts 103 and the limiting grooves 205, the positions of the first component 100 and the second component 200 can be positioned.

[0087] In some feasible embodiments of this application, the length of the limiting post 103 can be shorter than the length of the connecting post 11. When the handle 12 is in the second position, the end of the limiting post 103 contacts the bottom of the limiting groove 205, which can limit the relative shortening distance between the first main body plate 10 and the second main body plate 20, and prevent the shortening distance between the first main body plate 10 and the second main body plate 20 from being too large, which could lead to damage to the cascade plate 300 and the connecting piece 400. When a limiting protrusion 142 is provided, it can work in conjunction with the limiting protrusion 142 to provide a double protection effect, which is more effective. At the same time, in some feasible embodiments, the diameter of the limiting post 103 can be larger than the diameter of the connecting post 11, so that the limiting post 103 cannot extend into the connecting hole 201. Through this setting, the limiting post 103 and the limiting groove 205 can play a foolproof role, so as to ensure accurate alignment of the first component 100 and the second component 200.

[0088] The limiting post 103 includes, but is not limited to, being threadedly fixed to the first main body plate 10. For example, if the first main body plate 10 has a threaded hole, one end of the limiting post 103 has a thread, and the limiting post 103 is threadedly connected to the first main body plate 10. To facilitate the connection between the limiting post 103 and the limiting groove 205, a shrinkage groove is provided on the end of the limiting post 103 away from the first main body plate 10. The setting method of the shrinkage groove 113 can refer to the setting method of the shrinkage groove 113 on the connecting post 11, and will not be described again here. When the limiting post 103 is inserted into the limiting post 205, the end of the limiting post 103 can shrink into the shrinkage groove, so that the limiting post 103 can be inserted into the limiting groove 205.

[0089] Further, see also Figure 1 and Figure 3 To facilitate the operation of the second component 200, in this embodiment of the application, the second main body plate 20 is provided with a handle 206.

[0090] In summary, the technical solution provided in this application embodiment, by pressing the connecting piece 400 and the cascade plate 300 with the first component 100 and the second component 200, can connect multiple connecting pins 301 on the cascade plate 300 to multiple pin holes on the connecting piece 400 in one go, avoiding connecting them one by one, avoiding complicated and time-consuming operations, and quickly completing the connection between the connecting piece 400 and the cascade plate 300, saving effort and effectively improving efficiency, and has the characteristics of stable structure, simple operation and strong practicality.
