Description

A visual connection device for operation Technical Field

[0001] This utility model relates to the field of mobile device bracket technology, and in particular to a connection device for operation visualization. Background Technology

[0002] With the increasing popularity of mobile device stands, users are demanding greater convenience and reliability from their stand structures. Traditional mobile device stands often feature an integrated design of the base and stand body, which can lead to the entire device being unusable if the base is damaged. Therefore, the industry is gradually shifting towards detachable structural designs, such as those using snap-fit ​​mechanisms to allow for quick assembly and disassembly of the base and stand body. Specifically, such snap-fit ​​structures typically have a locking component with a spring-loaded reset function on the base, while the stand body has corresponding grooves or limiting protrusions for positioning. During assembly, the user presses the stand body onto the base, and the deformation of the elastic component engages the locking component with the limiting structure, locking the device in place. Disassembly requires external force to trigger a secondary deformation of the elastic component, causing the locking component to disengage from the limiting structure and unlocking the device.

[0003] In traditional technologies, the engagement state of the locking assembly cannot be directly observed because it is obscured by the main body of the bracket. Users can only infer the connection status through indirect features (such as the feel of pressing or minute operational gaps). For example, key information such as the actual engagement depth between the locking assembly and the limiting structure, and whether the elastic element has fully reset, are not visible. This can easily lead to misjudgment, resulting in a weak connection or difficulty in disassembly. Furthermore, non-professional users often cause structural damage such as buckle breakage or plastic deformation of the elastic element due to deviations in the direction of force or improper application of force. Summary of the Invention

[0004] The purpose of this utility model is to provide a connection device with visualized operation, so as to solve the technical problem mentioned in the background art: the engagement state of the locking component cannot be directly observed because it is blocked by the main body of the bracket, and the user can only infer the connection state through indirect features (such as pressing sensation or small operating gaps).

[0005] To achieve the above objectives, according to an embodiment of this application, an operational visualization connection device is provided, comprising: a first connecting member, wherein the first connecting member is provided with at least one locking component having an elastic reset function;

[0006] The second connecting member is provided with a limiting structure that cooperates with the locking assembly. The first connecting member and the second connecting member are assembled and connected through a concave-convex fitting structure. When the two are assembled, the locking assembly and the limiting structure form a mechanical interlock.

[0007] An operation feedback mechanism is provided, comprising a connecting part and a feedback part; the connecting part is linked to the locking assembly, and the feedback part is exposed on the outer surface of the first connecting member, and the feedback part is used to provide a visual indication of the activity status of the locking assembly.

[0008] In some possible implementations, a groove is provided on the outer surface of the first connecting member, and the connecting part and the feedback part pass through the groove, and the connecting part and the feedback part are used to reciprocate in the groove.

[0009] In some possible implementations, the connecting portion is located on the opposite side of the outer surface of the first connecting member.

[0010] In some possible implementations, the connecting part is provided with a fastening part, which fastens to the inner wall of the slide groove, the opposite side of the outer surface of the first connecting member, or the locking assembly.

[0011] In some possible implementations, the fastening part is elastic and the width of the fastening part is greater than the width of the groove, and the fastening part is fastened from one side of the outer surface of the first connecting member through the groove to the opposite side of the outer surface of the first connecting member.

[0012] In some possible implementations, the locking assembly includes: a locking member, the locking member including a sliding engagement portion and a functional extension portion, the first connecting member having a guide chamber, the sliding engagement portion being movably and elastically resettled within the guide chamber, and the functional extension portion extending outward from the guide chamber to form an exposed end, the exposed end having a fastening structure complementary to the limiting structure.

[0013] In some possible implementations, the groove is located on one side of the guide chamber, the sliding mating part is provided with a constraint groove, and the connecting part passes through the groove and is embedded in the constraint groove.

[0014] In some possible implementations, the interlocking structure includes an insertion protrusion on the first connecting member and an insertion cavity on the second connecting member. The locking assembly is located on the outside of the insertion protrusion, and the limiting structure is located on the inside of the insertion cavity. When the insertion protrusion is inserted into the insertion cavity, the locking assembly and the limiting structure form a mechanical interlock.

[0015] The locking assembly is provided in two parts, which are symmetrically distributed on the two outer sides of the insertion protrusion; the limiting structure is provided in two parts, which are symmetrically distributed on the two inner sides of the insertion cavity.

[0016] In some possible implementations, the operation visualization connection device further includes: a base pad, which is rotatably connected to the first connecting member, the end face of the first connecting member facing the base pad having an elastic positioning member, and the base pad having a plurality of positioning recesses spaced circumferentially at intervals on the corresponding end face of the first connecting member, the elastic positioning member being used to be embedded in the positioning recesses and to form a rotational positioning engagement with each positioning recess.

[0017] In some possible implementations, the feedback unit includes an indication structure for providing a visual indication of the activity status of the latch assembly and a force-applying contact structure for manually driving the operation feedback mechanism.

[0018] The operation-visualized connection device provided in this embodiment of the utility model, by setting an operation feedback mechanism and linking it with the locking assembly through the connecting part, with the feedback part exposed on the outer surface of the first connecting member, can display the activity status of the locking assembly in real time and intuitively.

In addition, since the operation feedback mechanism can provide real-time status indication of the locking assembly, users can more accurately judge whether the connection is in place, avoiding structural damage caused by deviation of the force direction or improper force, such as buckle breakage or plastic deformation of elastic elements. This not only improves the operational reliability of the connection device, but also extends its service life. Attached Figure Description

Detailed Implementation

[0027] The overall concept of the technical solution provided by this utility model is as follows:

[0028] Please refer to Figures 1 to 7. An operation visualization connection device includes: a first connecting member 100, a second connecting member 300, and an operation feedback mechanism 500, wherein:

[0029] The first connecting member 100 is provided with at least one locking assembly 200 with elastic reset function; the main body of the locking assembly 200 is responsible for engaging and locking with the limiting structure 400 of the second connecting member 300. Its design usually includes protrusions, grooves or other shapes to ensure a stable mechanical interlock during assembly. The first connecting member 100 is provided with the locking assembly 200 with elastic reset function to achieve a stable connection with the second connecting member 300.

[0030] The locking assembly 200 has an elastic reset function, which means that during the assembly process, the locking assembly 200 can cooperate with the limiting structure 400 of the second connecting member 300 through its own elastic deformation to achieve mechanical interlocking; mechanical interlocking means that the locking assembly 200 and the limiting structure 400 form an irreversible locking state through physical contact and engagement, ensuring that the connecting device will not be accidentally loosened or separated during use.

[0031] To achieve the elastic reset function, the locking assembly 200 may be provided with an elastic element 220 that can provide elasticity. When the user presses the first connecting member 100 onto the second connecting member 300, the elastic element 220 deforms and stores elastic potential energy. After assembly, the elastic element 220 releases the stored potential energy, pushing the locking assembly 200 to engage with the limiting structure 400 to achieve locking. When disassembling, the user needs to overcome the elastic force of the elastic element 220 to disengage the locking assembly 200 from the limiting structure 400.

[0032] Depending on actual needs, the number of locking components 200 can be one or more to ensure a secure connection in different directions and positions.

[0033] The second connecting member 300 is provided with a limiting structure 400 that cooperates with the locking assembly 200. The first connecting member 100 and the second connecting member 300 are assembled and connected through a convex-concave mating structure. When the two are assembled, the locking assembly 200 and the limiting structure 400 form a mechanical interlock. Specifically, the first connecting member 100 and the second connecting member 300 are assembled and connected through a convex-concave mating structure. The convex-concave mating structure is a common mechanical connection method. For example, the protruding part on the first connecting member 100 can cooperate with the groove part on the second connecting member 300 to achieve precise positioning and locking.

[0034] The shape and size of the limiting structure 400 should fit tightly with the protrusions, grooves, or other engaging parts of the locking assembly 200. Common forms of the limiting structure 400 include protrusions, grooves, and slots. These structures guide the locking assembly 200 into the correct position during assembly and prevent displacement or loosening during use. During assembly, the user presses the first connecting member 100 and the second connecting member 300 together. The locking assembly 200 begins to contact the limiting structure 400. As the pressing continues, the elastic element 220 of the locking assembly 200 deforms, storing elastic potential energy. When the locking assembly 200 is fully in the correct position of the limiting structure 400, the elastic element 220 releases its potential energy, pushing the locking assembly 200 to engage with the limiting structure 400, forming a mechanical interlock.

[0035] The operation feedback mechanism 500 includes a connecting part 520 and a feedback part 510. The connecting part 520 is linked to the locking assembly 200, and the feedback part 510 is exposed on the outer surface 140 of the first connecting member. The feedback part 510 is used to provide a visual indication of the activity status of the locking assembly 200. The main function of the operation feedback mechanism 500 is to monitor the activity status of the locking assembly 200 in real time and present this status to the user in a visual manner through the feedback part 510. By observing the feedback part 510, the user can clearly understand the movement status of the locking assembly 200, thereby avoiding misoperation and improving the controllability and safety of operation.

[0036] The connecting part 520 is linked to the locking assembly 200 to transmit the movement of the locking assembly 200 to the operation feedback mechanism 500. The connecting part 520 and the locking assembly 200 can be linked through mechanical connections such as threaded connections, tongue-and-groove connections, and magnetic connections. The feedback part 510 is designed to be exposed on the outer surface 140 of the first connecting member to ensure that the user can intuitively observe its status changes. Visual indicators can be provided on the feedback part 510, such as sliders and pointers, to directly display the position changes of the locking assembly 200.

[0037] By setting up an operation feedback mechanism 500 and linking it with the locking assembly 200 through the connecting part 520, the feedback part 510 is exposed on the outer surface 140 of the first connecting member. It can display the activity status of the locking assembly 200 in real time and intuitively. Users do not need to rely on indirect features (such as pressing sensation or small operating gaps) to infer the connection status. Instead, they can directly observe the feedback part 510 to clearly understand whether the locking assembly 200 has been correctly engaged or unlocked. This effectively avoids the problem of loose connection or difficulty in disassembly caused by misjudgment. In addition, since the operation feedback mechanism 500 can provide real-time status indication of the locking assembly 200, users can more accurately judge whether the connection is in place. This avoids structural damage caused by deviation of the force direction or improper force, such as buckle breakage or plastic deformation of the elastic element 220. This not only improves the operational reliability of the connection device, but also extends its service life.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please refer to Figures 3 to 5. A groove 112 is provided on the outer surface 140 of the first connecting member. The connecting part 520 and the feedback part 510 pass through the groove 112 and are used to reciprocate within the groove 112. The groove 112 is a groove-shaped structure provided on the outer surface 140 of the first connecting member, used to accommodate and guide the reciprocating movement of the connecting part 520 and the feedback part 510. The groove 112 is designed to be elongated. The connecting part 520 is a part of the operation feedback mechanism 500 associated with the feedback part 510 and is designed to reciprocate within the groove 112 together with the feedback part 510. Its main function is to transmit the movement of the locking assembly 200 to the feedback unit 510 to indicate or control the state of the locking assembly 200. The feedback unit 510 is part of the operation feedback mechanism 500 and is designed to move back and forth in the slide 112. It is mainly used to convert the state change of the locking assembly 200 into a visual indication signal and display it to the user through its own movement.

[0040] Furthermore, the connecting portion 520 is located on the opposite side of the outer surface 140 of the first connecting member, and the connecting portion 520 enters the opposite side of the outer surface 140 of the first connecting member from the outer surface 140 of the first connecting member by passing through the slide groove 112.

[0041] Furthermore, the connecting part 520 is provided with a fastening part 521, which fastens to the inner wall of the slide groove 112, the opposite side of the outer surface 140 of the first connecting member, or the locking assembly 200. The shape and size of the fastening part 521 are designed according to its mating object (such as the inner wall of the slide groove 112, the opposite side of the outer surface 140 of the first connecting member, or the locking assembly 200). Common shapes of the fastening part 521 include hooks, protrusions, and slots. The main function of the fastening part 521 is to achieve a stable connection between the connecting part 520 and the mating object, and to prevent the connecting part 520 from loosening or falling off during movement.

[0042] Furthermore, the interlocking connection between the fastening part 521 and the locking assembly 200 can be achieved through a concave-convex mating structure, thereby realizing the synchronous movement of the connecting part 520 and the locking assembly 200. Specifically, the concave-convex mating structure refers to the mutual cooperation between protruding parts (such as protrusions, bumps, protrusions, etc.) and recessed parts (such as grooves, pits, bayonets, etc.) to realize the connection and movement transmission between the two components.

[0043] Furthermore, a protruding structure can engage with a slide rail or mating surface to form a fastening connection, allowing the fastening part 521 to engage with the inner wall of the slide groove 112 or the opposite side of the outer surface 140 of the first connecting member, thus allowing the connecting part 520 to slide freely within the slide groove 112. For example, the fastening part 521 is a protruding structure on the connecting part 520, and the slide rail is a slide rail structure provided on the inner wall of the slide groove 112 to guide the movement of the protruding structure and achieve the fastening. This engagement method ensures that the connecting part 520 can maintain smooth sliding during movement. In another embodiment, the fastening part 521 is elastic, and the width of the fastening part 521 is greater than the width of the slide groove 112. The fastening part 521 is fastened from one side of the outer surface 140 of the first connecting member through the slide groove 112 to the opposite side of the outer surface 140 of the first connecting member. The fastening part 521 is designed to be elastic, allowing it to deform under external force and automatically return to its original shape after the force is released. The main function of this elasticity is to allow the fastening part 521 to deform flexibly during assembly and disassembly, thus passing through the slide groove 112. The width of the fastening part 521 is designed to be greater than the width of the slide groove 112, so that the fastening part 521 cannot pass directly through the slide groove 112 under normal conditions; it needs to undergo elastic deformation to achieve engagement. Due to its elasticity, the width of the fastening part 521 can be temporarily reduced under external force, allowing it to pass through the slide groove 112, and it returns to its original shape after the force is released, achieving engagement between the fastening part 521 and the mating surface opposite to the outer surface 140 of the first connecting member. The elastic engagement design of the fastening part 521, through its own elastic deformation and self-engaging mechanism, achieves the connection with the slide groove 112 and the opposite side of the outer surface 140 of the first connecting member.

[0044] Referring to Figures 3 and 4, the locking assembly 200 includes a locking member 210, which includes a sliding engagement portion 211 and a functional extension portion 212. A guide chamber 110 is provided on the first connecting member 100. The sliding engagement portion 211 is movably and elastically reset within the guide chamber 110. The functional extension portion 212 extends outward from the guide chamber 110 to form an exposed end, which has a fastening structure 2120 complementary to the limiting structure 400. Specifically, the locking member 210 is used for precise engagement and locking with the limiting structure 400 of the second connecting member 300. The locking member 210 includes two main parts: the sliding engagement portion 211 and the functional extension portion 212.

[0045] The guide chamber 110 is a cavity structure provided on the first connecting member 100, used to accommodate the sliding fit part 211 and provide it with precise guidance; the sliding fit part 211 can slide within the guide chamber 110, so that the locking member 210 can be adjusted according to the position of the limiting structure 400 during assembly and disassembly to ensure precise fit.

[0046] The sliding engagement part 211 not only slides but also has an elastic reset function, which allows the sliding engagement part 211 to maintain the engagement between the locking member 210 and the limiting structure 400 under the action of elastic force. When disassembling, the user needs to overcome the elastic force to make the locking member 210 disengage from the limiting structure 400. In order to realize the elastic reset function of the sliding engagement part 211, elastic elements such as springs and elastic washers are usually provided in the guide chamber 110. These elastic elements can store elastic potential energy during the sliding process of the locking member 210 and release it when needed to push the locking member 210 back to the initial position.

[0047] The exposed end of the functional extension 212 extends outward from the guide chamber 110 and is responsible for cooperating with the limiting structure 400 of the second connecting member 300. The exposed end of the functional extension 212 is provided with a fastening structure 2120 that complements the limiting structure 400, such as a protrusion, a groove, or a locking tooth. These fastening structures 2120 can engage with the limiting structure 400 during assembly to form a mechanical interlock and ensure the stability of the connection.

[0048] In one embodiment, referring to FIG3, the locking assembly 200 further includes an elastic element 220, the first end of which is connected to the locking element 210, and the second end of which is connected to the constraint wall of the guide chamber 110; wherein, the elastic element 220 is used to accumulate reset potential energy when the locking element 210 is displaced by an external force, and to drive the locking element 210 to return to the initial position after the external force is released. Specifically, the first end of the elastic element 220 is connected to the locking element 210, which can be a direct mechanical connection or a connection through an intermediate component (such as a hook, buckle, etc.); the second end of the elastic element 220 is connected to the constraint wall of the guide chamber 110. The constraint wall is part of the guide chamber 110 and is used to limit the displacement range of the elastic element 220 and provide a stable support point. When the locking element 210 is subjected to an external force (such as when the user presses the first connecting member 100 for assembly), the locking element 210 is displaced in the guide chamber 110, and the elastic element 220 is compressed or stretched, accumulating elastic potential energy. When the external force is released, the elastic element 220 releases the accumulated elastic potential energy, driving the locking element 210 to return to its initial position. During assembly, the user presses the first connecting member 100 and the second connecting member 300 together. The sliding engagement part 211 of the locking member 210 slides in the guide chamber 110, and the functional extension part 212 enters the engagement position of the limiting structure 400. As the pressing continues, the elastic member 220 is compressed, accumulating elastic potential energy. When the fastening structure 2120 of the functional extension part 212 is fully engaged with the limiting structure 400, the elastic member 220 stops further compression, and the locking member 210 and the limiting structure 400 form a stable mechanical interlock. During disassembly, the user needs to overcome the elastic force of the elastic member 220 to make the sliding engagement part 211 of the locking member 210 slide in the guide chamber 110. After the functional extension part 212 disengages from the limiting structure 400, the elastic member 220 releases its elastic force, driving the locking member 210 back to its initial position, ready for the next assembly.

[0049] To ensure that the elastic element 220 can provide a stable elastic restoring force over a long period of time, materials with high elasticity and durability, such as spring steel, silicone rubber or other elastic polymers, are usually selected. These materials can maintain their elastic properties during repeated use and are not prone to plastic deformation or breakage.

[0050] Please refer to Figures 3, 4, and 7. The sliding fit portion 211 is provided with one of a limiting protrusion 111 or a limiting groove 2110, and the guide chamber 110 is provided with the other of a limiting protrusion 111 or a limiting groove 2110. The limiting groove 2110 extends along the sliding direction of the sliding fit portion 211, and the limiting protrusion 111 is used to slide within the limiting groove 2110. Specifically, if the sliding fit portion 211 is provided with a limiting protrusion 111, then the guide chamber 110 is provided with a limiting groove 2110; conversely, if the sliding fit portion 211 is provided with a limiting groove 2110, then the guide chamber 110 is provided with a limiting protrusion 111.

[0051] The limiting groove 2110 extends along the sliding direction of the sliding fit 211. The limiting groove 2110 can be an elongated groove whose length and direction match the movement trajectory of the sliding fit 211, ensuring that the limiting protrusion 111 can slide smoothly within the limiting groove 2110. The shape and size of the limiting protrusion 111 should match the limiting groove 2110 to ensure that the two can fit tightly together. Common shapes of the limiting protrusion 111 include cylindrical, rectangular, and trapezoidal shapes, and the specific shape can be designed according to actual needs. The limiting groove 2110 provides a precise sliding path for the limiting protrusion 111, ensuring that the sliding mating part 211 can move along a predetermined trajectory within the guide chamber 110. This prevents the sliding mating part 211 from deviating or getting stuck during movement, improving the stability and reliability of the movement. The length of the limiting groove 2110 can limit the maximum displacement range of the sliding mating part 211. For example, the limiting protrusion 111 can contact the end of the limiting groove 2110 to limit the maximum displacement of the sliding mating part 211 and prevent it from dislodging from the guide chamber 110.

[0052] Referring to Figure 7, the limiting structure 400 includes a first constraint surface 410 extending radially, and the fastening structure 2120 includes a second constraint surface 2121 for abutting against the first constraint surface 410. When the first constraint surface 410 abuts against the second constraint surface 2121, the axial travel of the limiting structure 400 and the fastening structure 2120 is restricted. When the locking assembly 200 is fully engaged with the limiting structure 400, the first constraint surface 410 abuts against the second constraint surface 2121, restricting the axial travel of the limiting structure 400 and the fastening structure 2120, preventing the locking assembly 200 from moving further axially, thereby preventing it from disengaging from the limiting structure 400 and forming a stable mechanical connection. This abutting engagement ensures that the locking assembly 200 maintains a stable locked state after assembly.

[0053] Referring to Figure 3, the slide groove 112 is located on one side of the guide chamber 110. The sliding mating part 211 is provided with a constraint groove 2111. The connecting part 520 passes through the slide groove 112 and is embedded in the constraint groove 2111. The constraint groove 2111 is a recessed structure on the surface of the sliding mating part 211. The constraint groove 2111 is a groove-shaped structure with a certain depth and width, and its shape and size are designed to accommodate and fit the connecting part 520. The shape and size of the connecting part 520 should also match the constraint groove 2111 to ensure that it can be smoothly embedded in the groove. One end of the connecting part 520 is connected to the feedback part 510 of the operation feedback mechanism 500, and the other end is embedded in the constraint groove 2111 to realize linkage with the sliding mating part 211. Specifically, the movement of the sliding mating part 211... The movement of the sliding engagement part 2111 is transmitted through the constraint groove 2111. Since the constraint groove 2111 and the sliding engagement part 211 are integrated, the movement of the sliding engagement part 211 will drive the constraint groove 2111 to move synchronously. The movement of the constraint groove 2111 will drive the connecting part 520 that it engages with to move. The connecting part 520 receives the movement from the constraint groove 2111 and transmits it to the operation feedback mechanism 500. The feedback part 510 of the operation feedback mechanism 500 moves accordingly according to the movement of the connecting part 520, so that the feedback part 510 can indicate the movement state of the sliding engagement part 211, that is, the movement state of the locking assembly 200.

[0054] Please refer to Figures 1, 3, and 4. The interlocking structure includes an insertion protrusion 130 on the first connecting member 100 and an insertion cavity 310 on the second connecting member 300. A locking assembly 200 is located on the outer side of the insertion protrusion 130, and a limiting structure 400 is located on the inner side of the insertion cavity 310. When the insertion protrusion 130 is inserted into the insertion cavity 310, the locking assembly 200 and the limiting structure 400 form a mechanical interlock. Specifically, the insertion protrusion 130 is a part of the first connecting member 100 and is designed in a protruding shape for insertion into the second connecting member 300. In the insertion cavity 310 of component 300, the main function of the insertion protrusion 130 is to realize the assembly connection between the first connecting component 100 and the second connecting component 300. The insertion cavity 310 is part of the second connecting component 300 and is designed to be recessed to accommodate the insertion protrusion 130. The insertion cavity 310 can also be a through hole structure provided on the second connecting component. The main function of the insertion cavity 310 is to provide a precise mating space for the insertion protrusion 130, so as to ensure that the two can achieve precise positioning and stable connection during the assembly process.

[0055] The device includes two locking assemblies 200, symmetrically distributed on both outer sides of the insertion protrusion 130; and two limiting structures 400, symmetrically distributed on both inner sides of the insertion cavity 310. The main function of the locking assemblies 200 is to cooperate with the limiting structures 400 to achieve mechanical interlocking. When the insertion protrusion 130 is inserted into the insertion cavity 310, the locking assemblies 200 and the limiting structures 400 engage, forming a stable locked state to prevent loosening or separation of the connecting device during use. The symmetrical distribution of the two locking assemblies 200 on both outer sides of the insertion protrusion 130 ensures that the connecting device maintains balance and stability during assembly and locking. The symmetrical distribution of the two limiting structures 400 on both inner sides of the insertion cavity 310 matches the distribution of the locking assemblies 200, ensuring precise engagement between the locking assemblies 200 and the limiting structures 400 to achieve a stable lock.

[0056] Referring to Figure 5, the feedback unit 510 includes an indicator structure 511 for providing a visual indication of the activity status of the locking assembly 200 and a force-applying contact structure 512 for manually driving the operation feedback mechanism 500. The feedback unit 510 is a visual structure in the operation feedback mechanism 500 used to provide feedback to the user on the activity status of the locking assembly 200. For example, the feedback unit 510 may have an arrow indicating the direction of movement of the locking assembly 200. The arrow can indicate the direction in which the user needs to apply force, or display the current movement trend of the locking assembly 200, helping the user to more intuitively understand how to operate it.

[0057] The force-applying contact structure 512 is a component on the feedback unit 510 for manual operation by the user. It can be designed with a shape that facilitates force application, such as a protrusion, a groove, or a button. The user can apply force to the force-applying contact structure 512 with their fingers or tools, thereby driving the operation feedback mechanism 500. The force-applying contact structure 512 allows the user to manually drive the operation feedback mechanism 500. The movement of the operation feedback mechanism 500 is transmitted to the locking assembly 200 to adjust the state of the locking assembly 200. For example, in some cases, the user may need to manually unlock the connection between the locking assembly 200 and the limiting structure 400. At this time, force can be applied to the force-applying contact structure 512 to drive the force-applying contact structure 512 to move and cause the locking assembly 200 to disengage from the limiting structure 400.

[0058] Please refer to Figures 2 to 4. The connection device for operation visualization also includes: a base pad 600, which is rotatably connected to the first connecting member 100. The end face of the first connecting member 100 facing the base pad 600 is provided with an elastic positioning member 120. The corresponding end face of the base pad 600 facing the first connecting member 100 is circumferentially distributed with a plurality of positioning recesses 610. The elastic positioning member 120 is used to be embedded in the positioning recesses 610 and form a rotational positioning engagement with each positioning recess 610. The base pad 600 is the bottom support component of the operation visualization connection device. It is rotatably connected to the first connecting member 100. Its main function is to provide stable support for the entire visualization connection device and allow the first connecting member 100 to rotate and adjust on it. The material of the base pad 600 should have sufficient wear resistance and anti-slip properties, such as rubber or silicone, to ensure that it will not slip or wear during use. The bottom of the base pad 600 may be provided with adhesive 700 to stick and fix the base pad 600 to a designated position. The adhesive 700 can also be replaced with a suction cup or magnetic adsorption structure to adapt to different usage scenarios.

[0059] More specifically, the elastic positioning element 120 is disposed on the end face of the first connecting member 100 facing the base pad 600, and is used to cooperate with the positioning recess 610 on the base pad 600 to achieve rotational positioning. It can be designed as a structure with a certain degree of elasticity, such as a spring sheet or an elastic protrusion. The positioning recess 610 is a plurality of recessed structures circumferentially spaced on the corresponding end face of the base pad 600 facing the first connecting member 100. Its main function is to cooperate with the elastic positioning element 120 to achieve rotational positioning. The main function of the elastic positioning element 120 is to cooperate with the positioning recess 610 on the base pad 600 to lock the rotational position of the first connecting member 100. By embedding in the positioning recess 610, the elastic positioning element 120 can prevent the first connecting member 100 from rotating accidentally after adjustment, ensuring that it remains in the user-set position.

[0060] The elastic positioning element 120 can also be a component formed by combining a spring and a steel ball. One end of the spring can be fixed to the first connecting member 100, and the other end contacts the steel ball. When the steel ball is subjected to an external force, the spring is compressed, accumulating elastic potential energy. After the external force is released, the spring releases its potential energy, pushing the steel ball back to its initial position. Under the push of the spring, the steel ball contacts the positioning recess 610 on the base pad 600 and embeds itself in the positioning recess 610, achieving positioning. The spring is compressed, accumulating elastic potential energy to ensure that the steel ball maintains a stable fit in the positioning recess 610. When rotational adjustment is required, the user needs to overcome the spring force to disengage the steel ball from the positioning recess 610. After disengagement, the first connecting member 100 can rotate freely on the base pad 600 until the user pushes the steel ball into a new positioning recess 610, thus achieving a new rotational positioning.
