Description

Technical Field

[0001] This invention relates to the field of adapter plug technology, and more specifically to a multi-in-one adapter plug. Background Technology

[0002] Currently, there are several mainstream plug / socket standards worldwide, which means that when people travel internationally, the plugs of their electrical devices may not be compatible with local sockets. To overcome the power supply barriers between different plugs and sockets, some manufacturers have developed adapters with multiple adjustable prongs and corresponding electrical products. These adapters have multiple sets of adjustable prongs; when using them, the required adjustable prongs need to be released and the others retracted into the plug.

[0003] Most existing movable prongs use a linear telescopic design. Under this design, the prong length determines the thickness of the plug body, making it difficult to control the plug's size when retracted. Movable prongs can also be configured with a rotatable folding prong design. This type of design is generally more advantageous for controlling the plug's size than the telescopic design. However, it's still difficult to accommodate multiple movable prongs in a smaller size, and after the desired prong is rotated out, it's crucial to ensure that the other prongs remain stationary to prevent electric shock. Therefore, the design is extremely challenging, and currently, no domestic manufacturers have developed such products. Summary of the Invention

[0004] The main objective of this invention is to provide a multi-function adapter plug that uses a folding pin design.

[0005] To achieve the above objectives, the present invention provides a multi-in-one adapter plug, which includes a main body having a first wall and a second wall facing each other in a first direction, and is characterized in that it further includes: The unlocking cover can move relative to the main body in a second direction orthogonal to the first direction, and the unlocking cover has a protruding pushing part on the side near the main body; The first movable member is hinged to the corresponding side of the first wall of the main body. The first movable member has a first external pin, a first pivot, and a first inner piece located inside the main body. The second movable member is hinged to the corresponding side of the second wall of the main body. The second movable member has a second external pin, a second pivot, and a second inner piece located inside the main body. Both the first pivot and the second pivot extend along a third direction orthogonal to the first and second directions. A first limiting mechanism for limiting the rotation of a first movable member, including a first transmission member and a first driven member; a second limiting mechanism for limiting the rotation of a second movable member, including a second transmission member and a second driven member, wherein at least a portion of the first transmission member and the second transmission member are located outside the main body. The multi-in-one adapter has a first state and a second state. In the first state, the pushing part abuts against the first transmission member, the projection of the first inner contact piece and the first driven member in the first direction does not coincide, and the projection of the second inner contact piece and the second driven member in the first direction coincides. In the second state, the pushing part abuts against the second transmission member, the projection of the second inner contact piece and the second driven member in the first direction does not coincide, and the projection of the first inner contact piece and the first driven member in the first direction coincides.

[0006] As can be seen from the above scheme, the two types of movable parts with external prongs, arranged in a folding-leg design on opposite sides of the main body, can make full use of the arrangement space on the outside of the main body and help to reduce the size of the main body. The unlocking cover can only unlock the corresponding movable part at a time by cooperating with one of the limiting mechanisms. The movable part can rotate to the working position where the external prongs protrude from the main body and the internal connector is connected to the internal circuit of the main body; the other limiting mechanism keeps the corresponding movable part locked, thereby restricting its rotation and keeping it in the storage position. Since the movable part faces the user, keeping it in the storage position can prevent the internal connector from connecting to the internal circuit of the main body, thereby preventing the user from being electrocuted.

[0007] A further embodiment is that the first and second transmission members can move along the second direction, and the first and second driven members can rotate along a plane defined by the second and third directions.

[0008] As can be seen from the above scheme, the movement mode of the two types of transmission components is linear movement consistent with the unlocking cover, so they can cooperate well with the unlocking cover and also help to reduce the design difficulty of related mechanisms. The rotation plane of the two types of driven components is perpendicular to the rotation plane of the two types of moving components, so the rotation of the moving components can be stopped or unlocked by a small range of movement, which also helps to reduce the first direction dimension of the main body.

[0009] A further embodiment includes two third walls facing each other in the third direction, with guide grooves provided on the third walls along the second direction. The first and second transmission members have trigger ends that cooperate with the pushing part, and the trigger ends pass through the guide grooves to exit the main body.

[0010] As can be seen from the above scheme, setting the trigger ends of the two types of transmission components to the third wall can make full use of the arrangement space on the outside of the main body and will not interfere with the two types of moving parts. The above arrangement idea is also conducive to the miniaturization of the main body.

[0011] A further improvement is that the multi-in-one adapter also includes a retaining structure that prevents the unlocking cover from moving relative to the main body in the first and second directions in the first and second states.

[0012] As can be seen from the above scheme, in order to maintain the unlocking cover's unlocking of specific moving parts, and at the same time prevent unlocking failure caused by user misoperation and accidental movement of the unlocking cover, it is necessary to introduce a retaining structure that restricts the movement of the unlocking cover relative to the main body in the first and second states.

[0013] A further embodiment is that two first ribs extending along the second direction are provided at intervals on each third wall. The unlocking cover includes two clamping wall portions facing each other in the third direction. The clamping wall portions are provided with a second rib and a third rib that are vertically connected on the side facing the third wall. The second ribs extend along the second direction. In the first state and the second state, the projections of the first rib and the second rib in the first direction coincide, and the projections of the third rib and the first rib in the second direction coincide. The retaining structure includes the clamping wall portion, the first rib, the second rib, and the third rib.

[0014] As can be seen from the above scheme, the cooperation between the second rib and the first rib can restrict the relative movement between the unlocking cover and the main body in the first direction, and the cooperation between the third rib and the first rib can restrict the relative movement between the unlocking cover and the main body in the second direction.

[0015] A further embodiment is that the unlocking cover also includes a cover portion connecting the two clamping walls. The cover portion covers the second wall in the first state and covers the first wall in the second state.

[0016] As can be seen from the above scheme, the cover plate can prevent the second movable member from rotating while covering the second wall, and can prevent the first movable member from rotating while covering the first wall. The cover plate can also cooperate with the second protruding rib to restrict the unlocking cover from moving relative to the main body in the first direction.

[0017] A further embodiment is that the multi-in-one adapter also includes a check structure that prevents the first driven member from rotating in the first state or prevents the second driven member from rotating in the second state. When the first movable member rotates to the point where the first external pin is perpendicular to the first wall in the first state, the check structure coincides with the projection of the first driven member in the third direction; or when the second movable member rotates to the point where the second external pin is perpendicular to the second wall in the second state, the check structure coincides with the projection of the second driven member in the third direction.

[0018] As can be seen from the above scheme, the introduction of a check valve structure can prevent the moving part from being accidentally locked due to misoperation of the limiting mechanism, ensuring that the moving part in the working state can rotate and smoothly return to the storage state, and preventing interference between the corresponding driven part and the inner plate during the rotation process.

[0019] A further alternative is that the check structure is a check part protruding from the first or second movable member, or the check structure is a check member movably disposed on the main body and driven by the first or second movable member.

[0020] As can be seen from the above scheme, the check structure can be set in a variety of forms. The check part protruding on the moving part is a relatively simple form of check structure setting, which is conducive to reducing the number of plug parts. The movable check part can be well adapted to the moving part and the corresponding driven part as a check structure.

[0021] A further option is that the multi-in-one adapter also includes an interlocking component, which is used to inhibit the movement of the second transmission component in the second direction in the first state and to inhibit the movement of the first transmission component in the second direction in the second state.

[0022] As can be seen from the above solution, the introduction of interlocking components can prevent users from removing the unlocking cover and then moving the transmission component corresponding to the retracted movable component to unlock the movable component, thereby eliminating the associated risk of electric shock, provided that the movable component is in the working state.

[0023] A further embodiment is that the interlocking component is a sliding plate that cooperates with the first and second transmission components. The sliding plate is located between the first and second transmission components on the same side in the third direction and can move along the first direction. The sliding plate includes a connecting section and a body section distributed along the second direction. The connecting section includes a straight edge parallel to the first direction and two oblique edges. The distance between the first and second transmission components in the first direction is D, the length of the straight edge is L1, and the length of the body section in the first direction is L2. Then, L1 < D < L2.

[0024] As can be seen from the above scheme, a sliding plate with a specific shape that can move along the first direction is a relatively simple implementation of the interlocking component. It can effectively prevent the first moving part and the second moving part from being unlocked at the same time, thereby eliminating the related electric shock hazard.

[0025] The multi-in-one adapter of this invention features two types of movable parts with a folded-leg design, positioned on opposite sides of the main body. This design fully utilizes the space on the outer side of the main body and facilitates miniaturization of the overall adapter structure. The unlocking cover, in conjunction with a limiting mechanism, unlocks the movable part located on one side of the main body. The movable part on the other side of the main body is locked by the corresponding limiting mechanism and simultaneously shielded by the unlocking cover, effectively preventing electric shock. The interlocking components and check valve structure further prevent the risk of electric shock due to misoperation. Attached Figure Description

Detailed Implementation

[0046] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings. In the following description, the same reference numerals are used for the same components, and repeated descriptions are omitted. Furthermore, the drawings are merely schematic diagrams, and the proportions of the components or their shapes may differ from actual dimensions. It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0048] Existing multi-in-one plugs mostly use a linear telescopic design for the movable prongs. This design is not conducive to controlling the size of the plug when it is folded. The movable prongs can also be configured with a rotatable folding prong design. Generally, this design is more conducive to controlling the size of the plug than the telescopic design. However, it is also difficult to accommodate multiple movable prongs in a small body of the plug. Furthermore, after the required prong is rotated out, it is necessary to ensure that the other prongs cannot be moved to prevent electric shock. Therefore, the design is extremely difficult.

[0049] See Figures 1 to 17 The multi-in-one adapter provided in this embodiment includes a main body 100, which is generally rectangular in shape. An XYZ coordinate system is established based on the main body 100, wherein the Z-axis is parallel to the height direction of the main body 100. The Z-axis can be defined as parallel to the plumb line direction, or more specifically, the +Z-axis can be defined as the opposite direction of the plumb line direction. The X-axis and Y-axis are both orthogonal to the Z-axis, and can specifically be two horizontally extending and orthogonal directions. Here, the length and width directions of the main body 100 are defined as the X-axis and Y-axis directions, respectively. Furthermore, the Y-axis is defined as the first direction, the Z-axis as the second direction, and the X-axis as the third direction.

[0050] The main body 100 includes a housing 110 and a support portion 120 disposed within the housing 110. The main body 100 has a first wall 110a and a second wall 110b opposing each other in the Y-axis direction (first direction). The main body 100 also includes two third walls 110c opposing each other in the X-axis direction (third direction) and a fourth wall 110d located on the +Z-axis side. The first wall 110a, the second wall 110b, the third wall 110c, and the fourth wall 110d can all be considered as part of the housing 110. A wire 115 is connected to the main body 100 on the -Z-axis side, and the wire 115 connects to the internal wiring of the main body 100 (not shown in the figure).

[0051] Furthermore, the multi-in-one adapter provided in this embodiment also includes an unlocking cover 200, a first movable member 130, a second movable member 140, a first limiting mechanism 150, and a second limiting mechanism 160. The unlocking cover 200 is movable relative to the main body 100 along the Z-axis direction (second direction), and the unlocking cover 200 has a protruding pushing part 210 on the side near the main body 100.

[0052] The first movable member 130 is hinged to the +Y axis direction side of the main body 100, that is, the side corresponding to the first wall 110a. The first movable member 130 has a first external pin 131, a first pivot 132, and a first internal tab 133 located within the main body 100. The second movable member 140 is hinged to the -Y axis direction side of the main body 100, that is, the side corresponding to the second wall 110b. The second movable member 140 has a second external pin 141, a second pivot 142, and a second internal tab 143 located within the main body 100. Both the first pivot 132 and the second pivot 142 extend along the X-axis direction.

[0053] The first limiting mechanism 150 is used to limit the rotation of the first movable member 130, and includes a first transmission member 151 and a first driven member 152; the second limiting mechanism 160 is used to limit the rotation of the second movable member 140, and includes a second transmission member 161 and a second driven member 162, wherein the first transmission member 151 and the second transmission member 161 are both located at least partially outside the main body 100.

[0054] The multi-in-one adapter has a first state and a second state. In the first state, the pushing part 210 abuts against the first transmission member 151, the projections of the first inner contact 133 and the first driven member 152 in the Y-axis direction do not coincide, and the projections of the second inner contact 143 and the second driven member 162 in the Y-axis direction do coincide. In the second state, the pushing part 210 abuts against the second transmission member 161, the projections of the second inner contact 143 and the second driven member 162 in the Y-axis direction do not coincide, and the projections of the first inner contact 133 and the first driven member 152 in the Y-axis direction do coincide.

[0055] The first movable member 130 and the second movable member 140, which contain pins, are designed with folded feet and are positioned on opposite sides of the main body 100 in the Y-axis direction. This design fully utilizes the space on the outer side of the main body 100 and facilitates a reduction in the size of the main body 100 and a miniaturization of the overall plug structure. The unlocking cover 200 can only unlock its corresponding first movable member 130 or second movable member 140 at a time by cooperating with either the first limiting mechanism 150 or the second limiting mechanism 160. For example, after unlocking the first movable member 130, it can be rotated to a working state where the first external pin 131 protrudes from the main body 100 and the first internal contact 133 is connected to the internal wiring of the main body 100. The second limiting mechanism 160 keeps the second movable member 140 locked. The rotation of the second movable member 140 is restricted by the second limiting mechanism 160 and thus maintained in a retracted state. Specifically, the second driven member 162 is on the rotational trajectory of the second inner contact 143. After the second movable member 140 rotates a certain angle, the second inner contact 143 interferes with the second driven member 162, thus restricting further rotation. Since the first movable member 130 faces the socket and the second movable member 140 faces the user, keeping the second movable member 140 in a retracted state prevents the second inner contact 143 from connecting to the internal wiring of the main body 100, thereby preventing the user from being electrocuted by contacting the second movable member 140. Conversely, if the second movable member 140 is unlocked, the first movable member 130 will also be locked by the first limiting mechanism 150 and kept in a retracted state, thereby preventing the user from being electrocuted by contacting the first movable member 130.

[0056] This embodiment includes one first movable member 130 and two second movable members 140. For ease of distinction, the two second movable members 140 are referred to as upper movable member 140a and lower movable member 140b, respectively. The first movable member 130 corresponds to the European standard, the upper movable member 140a corresponds to the British standard, and the lower movable member 140b corresponds to the American standard (same as the Chinese and Japanese standards). The first wall 110a and the second wall 110b are provided with receiving grooves 111 for accommodating the first movable member 130, the upper movable member 140a, and the lower movable member 140b, respectively. In the stored form, the first movable member 130, the upper movable member 140a, and the lower movable member 140b are located in their respective receiving grooves 111 and do not protrude from the main body 100.

[0057] In this embodiment, the first transmission member 151 and the second transmission member 161 can move along the Z-axis direction, and the first driven member 152 and the second driven member 162 can rotate along the XZ plane.

[0058] Theoretically, the first limiting mechanism 150 and the second limiting mechanism 160 can be implemented in various ways, specifically through structures such as linkages and gear transmissions. In this embodiment, the first transmission member 151 and the second transmission member 161 move linearly in accordance with the unlocking cover 200, thus enabling better cooperation with the unlocking cover 200 and reducing the design difficulty of the first limiting mechanism 150 and the second limiting mechanism 160. Since the rotation planes (XZ planes) of the first driven member 152 and the second driven member 162 are perpendicular to the rotation planes (YZ planes) of the first movable member 130 and the second movable member 140, respectively, they can prevent or unlock the rotation of the first movable member 130 or the second movable member 140 with a smaller range of motion, and also help reduce the Y-axis dimension of the main body 100.

[0059] In this embodiment, the first limiting mechanism 150 further includes a first guide rod 153 disposed within the housing 110, and the second limiting mechanism 160 further includes a second guide rod 163 disposed within the housing 110. Both the first guide rod 153 and the second guide rod 163 extend along the Z-axis direction and are connected to the support portion 120 at both ends in the Z-axis direction. One end of the first transmission member 151 and the second transmission member 161 located within the main body portion 100 is provided with a through hole along the Z-axis direction and is respectively sleeved onto the corresponding first guide rod 153 and second guide rod 163. Compression springs (not shown in the figure) are also sleeved on the first guide rod 153 and the second guide rod 163 to reset the first transmission member 151 and the second transmission member 161. The first follower 152 and the second follower 162 are both hinged to the support portion 120 and rotated back by a torsion spring that abuts against the outer shell 110. The first follower 152 and the second follower 162 have roughly the same structure, both having two rotating arms. One rotating arm cooperates with the first transmission member 151 or the second transmission member 161, and the other rotating arm can act on the first movable member 130 or the second movable member 140. The second follower 162 has a significantly different shape from the first follower 152 because it needs to cooperate with two second movable members 140. In most cases, there is no contact between the first transmission member 151 and the first driven member 152, or between the second transmission member 161 and the second driven member 162. Only when the first transmission member 151 and the second transmission member 161 are pushed a certain distance along the -Z axis by the corresponding pushing part 210 can they interact with the first driven member 152 or the second driven member 162 and rotate along the XZ plane until a rotating arm does not overlap with the projection of the first inner plate 133 or the second inner plate 143 in the Y axis direction.

[0060] This embodiment has two sets of first limiting mechanisms 150 and two sets of second limiting mechanisms 160. The former is set closer to the first wall 110a in the Y-axis direction, and the latter is set closer to the second wall 110b in the Y-axis direction. The unlocking cover 200 has only two pushing parts 210. Therefore, when the unlocking cover 200 is placed on the main body 100, it can only act on the two sets of first limiting mechanisms 150 or the two sets of second limiting mechanisms 160 at the same time.

[0061] A guide groove 112 is provided on the third wall 110c along the Z-axis direction. The first transmission member 151 has a first trigger end 151a that cooperates with the pushing part 210. The second transmission member 161 has a second trigger end 161a that cooperates with the pushing part 210. The first trigger end 151a and the second trigger end 161a pass through the corresponding guide groove 112 and exit the main body 100.

[0062] Setting the first trigger end 151a and the second trigger end 161a to the third wall 110c can make full use of the arrangement space outside the main body 100 and will not interfere with the first movable member 130 and the second movable member 140. The above arrangement idea is also conducive to the miniaturization of the main body 100.

[0063] The multi-in-one adapter also includes a retaining structure that prevents the unlocking cover 200 from moving relative to the main body in the Y-axis and Z-axis directions in the first and second states. Two first ribs 113 extending in the Z-axis direction are spaced apart on each third wall 110c. The unlocking cover 200 includes two opposing clamping wall portions 220 in the X-axis direction. Each clamping wall portion 220 has a vertically connected second rib 221 and a third rib 222 on the side facing the third wall 110c. The second rib 221 extends in the Z-axis direction. In the first and second states, the projections of the first rib 113 and the second rib 221 in the Y-axis direction coincide, and the projection of the third rib 222 and the first rib 113 in the Z-axis direction coincide. The retaining structure includes the clamping wall portion 220, the first rib 113, the second rib 221, and the third rib 222.

[0064] To maintain the unlocking of the unlocking cover 200 for the first movable member 130 or the second movable member 140, and to prevent unlocking failure caused by user misoperation or accidental movement of the unlocking cover 200, a retaining structure is needed to limit the movement of the unlocking cover 200 relative to the main body 100 in the first and second states. The cooperation between the second protruding rib 221 and the first protruding rib 113 restricts relative movement between the unlocking cover 200 and the main body 100 in the Y-axis direction, and the cooperation between the third protruding rib 222 and the first protruding rib 113 restricts relative movement between the unlocking cover 200 and the main body 100 in the Z-axis direction. Furthermore, the two clamping wall portions 220 cover the two third walls 110c in both the first and second states, preventing the user from forcibly unlocking the retracted movable member by directly actuating the relevant transmission components.

[0065] The unlocking cover 200 also includes a cover portion 230 and a top plate portion 240 that connect the two clamping wall portions 220. The cover portion 230 covers the second wall 110b in the first state and covers the first wall 110a in the second state. The top plate portion 240 covers the fourth wall 110d in both the first and second states.

[0066] The cover portion 230, while concealing the second wall 110b, can prevent the second movable member 140 from rotating. The cover portion 230, while concealing the first wall 110a, can also prevent the first movable member 130 from rotating. The cover portion 230, in conjunction with the second protruding rib 221, restricts the movement of the unlocking cover 200 relative to the main body 100 in the Y-axis direction. The top plate portion 240, in conjunction with the third protruding rib 222, restricts the movement of the unlocking cover 200 relative to the main body 100 in the Z-axis direction. The top plate portion 240, the cover portion 230, and the two clamping wall portions 220 together constitute the main body of the unlocking cover 200, giving the unlocking cover 200 high structural strength.

[0067] The multi-in-one adapter also includes a check structure that prevents the first driven member 152 from rotating in a first state or prevents the second driven member 162 from rotating in a second state. In the first state, when the first movable member 130 rotates to the position where the first external pin 131 is perpendicular to the first wall 110a, the check structure coincides with the projection of the first driven member 152 in the X-axis direction; or in the second state, when the second movable member 140 rotates to the position where the second external pin 141 is perpendicular to the second wall 110b, the check structure coincides with the projection of the second driven member 162 in the X-axis direction. In this embodiment, the check structure refers to a first check portion 134 protruding from the first movable member 130, a second check portion 144 protruding from the lower movable member 140b, and a check member 170 movably mounted on the support portion 120 and driven by the upper movable member 140a.

[0068] The introduction of a check valve structure can prevent the first moving part 130 or the second moving part 140 from being accidentally locked due to misoperation by the first limiting mechanism 150 or the second limiting mechanism 160. This ensures that the first moving part 130 or the second moving part 140 in the working state can rotate and smoothly return to the storage state, and prevents interference between the first driven part 152 and the first inner plate 133 or the second driven part 162 and the second inner plate 143 during the rotation process.

[0069] The first check valve 134 consists of two protruding structures extending along the Y-axis in the working state of the first movable member 130. The two first check valves 134 are located outside the two first inner tabs 133 in the X-axis direction. In some unexpected situations, such as when the unlocking cover 200 is removed from the main body 100, the first driven member 152 rotates and abuts against the first check valve 134, thus preventing the first driven member 152 from rotating in the initial stage of the process of the first movable member 130 changing from the working state to the storage state. Subsequently, the first driven member 152 disengages from the first check valve 134 and continues to rotate. At this time, the first inner tabs 133 are no longer on the movement trajectory of the first driven member 152, and therefore will not interfere with the first driven member 152. The first check valve 134 protruding from the first movable member 130 is a relatively simple check valve structure, which helps to reduce the number of components in the plug. The second check valve 144 consists of two columnar protrusions located at both ends of the lower movable member 140b in the X-axis direction. These columnar protrusions extend along the X-axis direction, and their function and the way they cooperate with the second driven member 162 are similar to those of the first check valve 134, so they will not be described in detail here.

[0070] This embodiment includes two stop members 170 located on both sides of the upper movable member 140a in the X-axis direction. The stop members 170 are hinged to the support portion 120 and can rotate along the YZ plane. The stop members 170 have a first rotating arm 171 that cooperates with the upper movable member 140a and a second rotating arm 172 that cooperates with the second driven member 162. The first rotating arm 171 is reset by means of a compression spring that abuts against the support portion 120 and can elastically deform in the Y-axis direction. In this embodiment, the second driven member 162 has a first arm portion 162a that cooperates with the second transmission member 161 and a second arm portion 162b that cooperates with the second rotating arm 172. The upper movable member 140a also includes an external pressure rod 145 extending in the X-axis direction. During the process of the upper movable member 140a changing from a retracted state to a working state, the external pressure rod 145 pushes the first rotating arm 171 to rotate the second rotating arm 172 until its projection in the X-axis direction coincides with that of the end of the second arm portion 162b. When the unlocking cover 200 is removed from the main body 100, the second follower 162 rotates to abut against the X-axis side of the second arm 162b. Therefore, the second arm 172 can prevent the second follower 162 from rotating in the initial stage of the process of the second movable member 140 changing from the working state to the storage state. Subsequently, the second follower 162 disengages from the second arm 172 and continues to rotate. At this time, the second inner tab 143 is no longer on the movement trajectory of the second follower 162, so it will not interfere with the second follower 162.

[0071] The three second external pins 141 of the upper movable member 140a constitute a relatively complex linkage transmission mechanism. The second driven member 162 is shaped like a sickle and has a relatively special shape. Therefore, setting the check structure as an independent check member 170 can better adapt to the second movable member 140 and the second driven member 162.

[0072] See Figure 4 , 6 11, 12, 16, 17. The multi-in-one adapter also includes an interlocking component, which is used to inhibit the movement of the second transmission member 161 along the Z-axis in a first state and to inhibit the movement of the first transmission member 151 along the Z-axis in a second state. In this embodiment, the interlocking component is a sliding plate 180 that cooperates with the first transmission member 151 and the second transmission member 161. The sliding plate 180 is located between the first transmission member 151 and the second transmission member 161 on the same side in the X-axis direction and can move along the Y-axis direction. The sliding plate 180 includes a connecting section 181 and a body section 182 distributed along the Z-axis direction. Figure 16(The boundary line between the joint section 181 and the body section 182 is indicated by a dashed line). The joint section 181 includes a straight edge 181a parallel to the Y-axis direction and two inclined edges 181b. The distance between the first transmission member 151 and the second transmission member 161 in the Y-axis direction is D. The length of the straight edge 181a is L1. The dimension of the body section 182 in the Y-axis direction is L2. Then L1 < D < L2.

[0073] Introducing an interlocking mechanism prevents the user from unlocking the second movable member 140 by removing the unlocking cover 200 and then moving the second transmission member 161, thus preventing the second inner contact piece 143 from connecting to the internal wiring of the main body 100 and eliminating the associated risk of electric shock, while the first movable member 130 is in the working state. Furthermore, while the second movable member 140 is in the working state, it also restricts the user from forcibly unlocking the first transmission member 151 through a similar operation. A sliding plate 180 with a specific shape and movable along the Y-axis is a relatively simple implementation of the interlocking mechanism, effectively preventing the first movable member 130 and the second movable member 140, which are positioned opposite each other in the Y-axis direction, from being unlocked simultaneously, thereby eliminating the associated risk of electric shock.

[0074] See Figure 17 A guide rail portion 114 is provided on the inner side of the third wall 110c along the Y-axis direction. The guide rail portion 114 is located on the -Z-axis side of the third wall 110c. The -Z side of the body segment 182 is embedded in the guide rail portion 114 and can move along the Y-axis direction. See also Figure 12 During the process of unlocking the second movable member 140, the second transmission member 161 located on the +X axis side moves along the -Z axis direction to the end of the guide groove 112 and interacts successively with the inclined edge 181b of the sliding plate 180 on the -Y axis side and the edge of the body section 182 on the -Y axis side, thereby pushing the sliding plate 180 towards the +Y axis direction. This causes the projection of the first transmission member 151 located on the +X axis side and the inclined edge 181b of the sliding plate 180 on the +Y axis side in the Z axis direction to coincide, thereby suppressing the movement of the first transmission member 151 along the -Z axis direction. Therefore, the first movable member 130 cannot be unlocked even after the unlocking cover 200 is removed.

[0075] Thanks to the anti-return structure and interlocking components, the multi-in-one adapter can still be used normally and safely by turning the first transmission component 151 or the second transmission component 161 even after the unlocking cover 200 is removed or lost.
