Description

Technical Field

[0001] The present invention relates to the technical field of sockets, and particularly to an expandable socket with a plug fixing structure. Background Art

[0002] The professional term for a socket is a power converter. With the deepening of human understanding of "electricity", the electrical appliance industry has developed rapidly, and various electrical appliances need to be connected and powered through sockets. Therefore, sockets play an important role in people's lives, workplaces, etc., providing convenience for powering more electrical appliances simultaneously.

[0003] In the current power usage methods, in addition to the fixed sockets pre-set indoors and outdoors, power supply sockets with extension cords are widely used as an extended access method for homes and workplaces.

[0004] Existing power supply sockets with extension cords are mostly of an integrated design, generally consisting of a wire and a socket body. Considering that the socket may need to power multiple electrical appliances, users often require multiple sets of jacks to be provided on one socket. Currently, the power supply sockets with extension cords sold on the market generally have two or more sets of jacks fixedly arranged on the socket body. Although this design solves the problem of powering multiple electrical appliances simultaneously, its disadvantages are also very obvious.

[0005] First of all, this kind of socket is prone to waste of resources. Since it is not known exactly how many electrical appliances need to be connected in advance, when users buy a multi-hole socket, they often hope to buy as many jack units as possible. A socket with more jack units necessarily requires more raw materials for production and is also bound to be sold at a higher price. When users have few electrical appliances, there will often be a large number of idle jacks on the multi-hole socket, resulting in waste. Secondly, this kind of socket cannot be expanded. In reality, such a scenario is often seen. Since the number of jacks on the socket purchased in advance is too small, the user's electrical appliances cannot be inserted into the socket simultaneously to draw power, thus causing great inconvenience to the user.

[0006] In addition, the jacks on the existing plugs and sockets are of a direct plug-and-unplug structure. During use, there may be a situation where the plug is accidentally unplugged, causing the device to lose power, affecting people's lives and work, and even causing danger.

[0007] For example, in the field of medical devices, the plug of a medical device is inserted into the jack of a medical socket to achieve power-on. However, if the plug is accidentally unplugged during the operation of the medical device, it will cause the medical device to stop working and even cause a medical accident. Therefore, according to the relevant regulations of medical device standards, medical sockets need to have a structure to prevent the plug from being unplugged due to accidental operation. Summary of the Invention

[0008] The object of the present invention is to provide an expandable socket with a plug fixing structure, which can not only solve the problem of inconvenient use in the prior art due to the integrated design of most sockets and the fixed number of jacks, but also fix the plug on the jack of the socket to prevent the plug from being accidentally pulled out of the socket.

According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and all use non - precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and understandable, please refer to the drawings. It should be known that the structures, scales, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have technical essential significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed by the present invention.

[0041] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In the description of the present invention, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0043] In the description of the present invention, unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled", "fixed" shall be construed broadly. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween.

The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0045] As introduced in the background art, the existing sockets cannot be expanded, causing great inconvenience to users. In addition, the jacks on the existing plugs and sockets are of a direct plugging and unplugging structure, and there may be a situation where the plug is accidentally unplugged during use, resulting in the device being powered off, affecting people's lives and work, and even causing danger.

[0046] The core idea of the present invention is to provide an expandable socket with a plug fixing structure to solve the problem of inconvenient use caused by the fact that most existing sockets are of an integrated design and the number of jacks is fixed. At the same time, the plug can be fixed on the jack of the socket to prevent the plug from being accidentally unplugged from the socket.

[0047] To achieve the above idea, the present invention provides an expandable socket with a plug fixing structure. Please refer to Figure 1 and Figure 2 , wherein Figure 1 schematically shows the overall structural diagram of the expandable socket with a plug fixing structure in an embodiment of the present invention. Figure 2 schematically shows the structural diagram of the expandable socket with a plug fixing structure in an embodiment of the present invention after removing one claw. As shown in Figure 1 and Figure 2 , the expandable socket includes a socket body and a fixing structure mounted on the socket body.

[0048] Please refer to Figures 1 to 3 , wherein Figure 3 schematically shows the partial exploded structural diagram of the expandable socket with a plug fixing structure in an embodiment of the present invention. As shown in Figures 1 to 3As shown, the socket body includes a basic socket 100 and at least one single socket 200. The connection between the basic socket 100 and the adjacent single socket 200, as well as between any two adjacent single sockets 200, is detachable. Both the basic socket 100 and the single socket 200 are provided with at least one set of jacks 300. One end of the basic socket 100 away from the single socket 200 is provided with a power socket 110 for external power connection. Thus, according to specific usage requirements, several single sockets 200 can be connected to the basic socket 100, thereby realizing the expansion of the socket, effectively solving the problem of inconvenient use in the prior art due to the integrated design of most sockets and the fixed number of jacks 300. It should be noted that although in Figure 1 and Figure 2 the expandable socket shown, the socket body includes a basic socket 100 and two single sockets 200, those skilled in the art should understand that the number of the single sockets 200 is not limited thereto. The number of the single sockets 200 can be 1, 3, 4, 5 or even more, and its specific number can be set according to specific circumstances. The present invention does not limit this.

[0049] Preferably, as shown in Figure 1 and Figure 2 the single socket 200 is provided with one set of jacks 300, the basic socket 100 is provided with multiple sets of jacks 300, and all the jacks 300 are three-hole jacks. Thus, by setting one set of jacks 300 on the single socket 200, waste of jacks 300 can be avoided. By setting multiple sets of jacks 300 on the basic socket 100, multiple electrical appliances can be powered simultaneously, which is more convenient for use. It should be noted that in some other embodiments, two sets or other numbers of jacks 300 can also be set on the single socket 200, and the jacks 300 on the single socket 200 and the basic socket 100 can be two-hole jacks. The present invention does not limit this.

[0050] Preferably, please refer to Figures 3 to 7 , in which Figure 4 schematically shows a structural diagram of the basic socket 100 in the expandable socket with a plug fixing structure in an embodiment of the present invention, Figure 5 schematically shows a structural diagram of the single socket 200 in the expandable socket with a plug fixing structure in an embodiment of the present invention, Figure 6 schematically shows a structural diagram of the single socket 200 from another angle in an embodiment of the present invention, Figure 7 schematically shows a structural diagram of the single socket 200 when the first conductive member 212 extends out in an embodiment of the present invention. As shown in Figures 3 to 7As shown, one end of the monomer socket 200 is provided with a first conductive connector, and the other end of the monomer socket 200 is provided with a second conductive connector. One end of the base socket 100 away from the monomer socket 200 is provided with a power socket 110 for external power supply, and one end of the base socket 100 close to the monomer socket 200 is provided with a third conductive connector for electrically connecting with the first conductive connector. Thus, two adjacent monomer sockets 200 can be connected together through the first conductive connector and the second conductive connector, that is, the second conductive connector of one monomer socket 200 is connected to the first conductive connector of another monomer socket 200; the adjacent base socket 100 and monomer socket 200 can be connected together through the first conductive connector and the third conductive connector.

[0051] Preferably, as Figure 5 and Figure 7 shown, the first conductive connector includes a first connection hole 211 and a first conductive member 212 disposed in the first connection hole 211. The first conductive member 212 can reciprocate axially along the monomer socket 200 in the first connection hole 211. Thus, when it is necessary to connect the base socket 100 and a monomer socket 200, the first conductive member 212 can be moved forward so that the first conductive member 212 moves in the direction toward the position of the third conductive connector close to the base socket 100 until the first conductive member 212 is electrically connected to the third conductive connector; when it is necessary to separate the monomer socket 200 from the base socket 100, the first conductive member 212 can be moved backward so that the first conductive member 212 moves in the direction away from the position of the base socket 100 until the first conductive member 212 is separated from the third conductive member. Similarly, when it is necessary to connect one monomer socket 200 and another monomer socket 200, the first conductive member 212 of one monomer socket 200 can be moved forward so that the first conductive member 212 moves in the direction toward the position of the second conductive connector of another monomer socket 200 until the first conductive member 212 is electrically connected to the second conductive connector; when it is necessary to separate the two connected monomer sockets 200, the first conductive member 212 on one of the monomer sockets 200 can be moved backward so that the first conductive member 212 moves in the direction away from the position of another monomer socket 200 until the first conductive member 212 is separated from the second conductive connector on another monomer socket 200. It can be seen that such a setting can not only simplify the overall structure of the expandable socket provided by the present invention, but also realize the rapid assembly and disassembly of the expandable socket, and the operation is more convenient.

[0052] Preferably, as Figure 6As shown, the second conductive connector includes a second connection hole 231 and a second conductive member (not shown in the figure) disposed within the second connection hole 231. Since the second conductive connector includes the second connection hole 231 and the second conductive member disposed within the second connection hole 231, the overall structure of the expandable socket provided by the present invention can be further simplified.

[0053] Preferably, as Figure 4 shown, the third conductive connector includes a third connection hole 121 and a third conductive member disposed within the third connection hole 121. Since the third conductive connector includes the third connection hole 121 and the third conductive member disposed within the third connection hole 121, the overall structure of the expandable socket provided by the present invention can be further simplified.

[0054] Preferably, the first conductive member 212 is a conductive post, the second conductive member is a conductive metal sheet attached to the inner wall of the second connection hole 231, and the third conductive member is a conductive metal sheet attached to the inner wall of the third connection hole 121. Thus, when the first conductive member 212 (conductive post) on one monomer socket 200 is inserted into the second connection hole 231 on another monomer socket 200, the first conductive member 212 (conductive post) can contact the second conductive member (conductive metal sheet) located within the second connection hole 231, thereby quickly realizing the electrical connection between the first conductive member 212 and the second conductive member. Similarly, when the first conductive member 212 (conductive post) on the monomer socket 200 is inserted into the third connection hole 121, the first conductive member 212 (conductive post) can contact the third conductive member (conductive metal sheet) located within the third connection hole 121, thereby quickly realizing the electrical connection between the first conductive member 212 and the third conductive member.

[0055] Preferably, the first conductive connector includes three first connection holes 211, and a first conductive member 212 is disposed within each of the first connection holes 211. One of the first conductive members 212 is used for connecting to the neutral wire, one of the first conductive members 212 is used for connecting to the live wire, and one of the first conductive members 212 is used for connecting to the ground wire. Correspondingly, the second conductive connector includes three second connection holes 231, and a second conductive member is disposed within each of the second connection holes 231. One of the second conductive members is used for connecting to the neutral wire, one of the second conductive members is used for connecting to the live wire, and one of the second conductive members is used for connecting to the ground wire. The third conductive connector includes three third connection holes 121, and a third conductive member is disposed within each of the third connection holes 121. One of the third conductive members is used for connecting to the neutral wire, one of the third conductive members is used for connecting to the live wire, and one of the third conductive members is used for connecting to the ground wire.

[0056] Preferably, as Figures 5 to 7As shown, a movable switch 220 connected to the first conductive member 212 is provided on the monomer socket 200. The movable switch 220 is used to control the reciprocating movement of the first conductive member 212 along the axial direction of the monomer socket 200. Thus, the first conductive member 212 can be reciprocally moved along the axial direction of the monomer socket 200 by moving the movable switch 220. Specifically, an installation hole (not shown in the figure) for installing the movable switch 220 is provided on the monomer socket 200. The installation hole is communicated with the first connection hole 211. At least a part of the movable switch 220 penetrates to the outside of the monomer socket 200, and the movable switch 220 can reciprocally move along the axial direction of the monomer socket 200. As Figure 5 and Figure 7 shown, when the movable switch 220 is moved to the right, the first conductive member 212 can be moved to the right, so that the first conductive member 212 can penetrate to the outside of the first connection hole 211; when the movable switch 220 is moved to the left, the first conductive member 212 can be moved to the left, so that the first conductive member 212 can be retracted into the first connection hole 211.

[0057] Preferably, as Figures 5 to 7 shown, the movable switch 220 is arranged on the side surface of the monomer socket 200. Thus, on the one hand, space can be saved, and on the other hand, it is more convenient to operate.

[0058] Preferably, as Figures 3 to 7As shown, a bump 240 is provided at one end of the single socket 200 close to the basic socket 100. The first conductive connector penetrates through the bump 240. Both sides of the end of the bump 240 away from the basic socket 100 are recessed inward. A first connection groove 250 is provided at one end of the single socket 200 away from the basic socket 100. The second conductive connector penetrates through one end of the first connection groove 250 close to the basic socket 100. A second connection groove 130 is provided at one end of the basic socket 100 close to the single socket 200. The third conductive connector penetrates through one end of the second connection groove 130 away from the single socket 200. Thus, when it is necessary to connect one single socket 200 to another single socket 200, the bump 240 on one of the single sockets 200 can be inserted into the first connection groove 250 on the other single socket 200, so that the first conductive connector penetrating through the bump 240 can be smoothly electrically connected to the second conductive connector penetrating through one end of the first connection groove 250. In addition, the stability of the connection between the two single sockets 200 can be improved by the mutually cooperating bump 240 and the first connection groove 250. Similarly, when it is necessary to connect one single socket 200 to the basic socket 100, the bump 240 on the single socket 200 can be inserted into the second connection groove 130 on the basic socket 100, so that the first conductive connector penetrating through the bump 240 can be smoothly electrically connected to the third conductive connector penetrating through one end of the second connection groove 130. At the same time, the stability of the connection between the single socket 200 and the basic socket 100 can be improved by the mutually cooperating bump 240 and the second connection groove 130.

[0059] Preferably, buckles 241 are provided on both sides of the bump 240, first card holes 251 are provided on both sides of the first connection groove 250, and second card holes 131 are provided on both sides of the second connection groove 130. Thus, when the bump 240 of one single socket 200 is inserted into the first connection groove 250 of another single socket 200, the buckles 241 on both sides of the bump 240 can be snapped into the correspondingly arranged first card holes 251, so that the bump 240 can be firmly fixed in the first connection groove 250, further improving the firmness of the connection between the two single sockets 200. Similarly, when the bump 240 of one single socket 200 is inserted into the second connection groove 130, the buckles 241 on both sides of the bump 240 can be snapped into the correspondingly arranged second card holes 131, so that the bump 240 can be firmly fixed in the second connection groove 130, further improving the firmness of the connection between the basic socket 100 and the single socket 200.

[0060] Preferably, first card slots 242 are provided on both sides of the bump 240. First engaging blocks 252 are provided inside both sides of one end of the first connection slot 250 away from the base socket 100. Second engaging blocks 132 are provided inside both sides of one end of the second connection slot 130 close to the single socket 200. Thus, when the bump 240 of one single socket 200 is inserted into the first connection slot 250 of another single socket 200, the first engaging block 252 can be engaged into the first card slot 242, so that the bump 240 can be more firmly fixed in the first connection slot 250, and further improve the firmness of the connection between the two single sockets 200. Similarly, when the bump 240 of one single socket 200 is inserted into the second connection slot 130, the second engaging block 132 can be engaged into the first card slot 242, so that the bump 240 can be more firmly fixed in the second connection slot 130, and further improve the firmness of the connection between the base socket 100 and the single socket 200.

[0061] Preferably, as Figure 5 shown, a first bottom plate 253 is provided at the bottom of the first connection slot 250. An opening is provided at the top of the first connection slot 250. The bottom of the bump 240 floats upward relative to the bottom of the single socket 200. Thus, the first bottom plate 253 can play a further supporting role for the bump 240 inserted into the first connection slot 250, and further improve the firmness of the connection between the two single sockets 200. In addition, by providing an opening at the top of the first connection slot 250, it is more convenient to insert the bump 240 of one single socket 200 into the first connection slot 250 of another single socket 200.

[0062] As Figure 4 shown, a second bottom plate 133 is provided at the bottom of the second connection slot 130. An opening is provided at the top of the second connection slot 130. Thus, by providing the second bottom plate 133 at the bottom of the second connection slot 130, the second bottom plate 133 can play a supporting role for the bump 240 inserted into the second connection slot 130, thereby further improving the firmness of the connection between the single socket 200 and the base socket 100. In addition, by providing an opening at the top of the second connection slot 130, it is more convenient for the connection between the single socket 200 and the base socket 100.

[0063] As Figure 1 and Figure 2As shown, the fixing structure includes at least two claws 400, which are arranged in one-to-one correspondence with the jacks 300. The claws 400 are used to fix the plug on the jacks 300, and the claws 400 are detachably connected to the socket body. Thus, the plug can be fixed on the jacks 300 of the socket through the fixing structure, effectively preventing the plug from being accidentally pulled out of the socket. Especially in the field of medical devices, by using the expandable socket provided by the present invention to supply power to medical equipment, medical accidents caused by accidental unplugging of the plug can be effectively avoided. In addition, since the claws 400 are detachably connected to the socket body, the corresponding number of claws 400 can be selected according to the number of jacks 300 on the socket body, so as to more conveniently achieve the purpose of fixing the plug on the jacks 300.

[0064] Preferably, please refer to Figure 8 , which schematically shows the structural diagram of the claw 400 in an embodiment of the present invention. As shown in Figure 8 , the claw 400 includes a fixing portion 410 for fixing the plug. A second card slot 420 is formed at one end of the fixing portion 410. The width of the second card slot 420 is smaller than the maximum width of the plug. Both ends of the fixing portion 410 are bent towards the position where the jack 300 is located to form a first connecting portion 430 and a second connecting portion 440. Among them, the first connecting portion 430 is away from the position where the second card slot 420 is located, and the second connecting portion 440 is close to the position where the second card slot 420 is located. The first connecting portion 430 is connected to one side of the socket body, and the second connecting portion 440 is connected to the other side of the socket body. Thus, after the plug is inserted into the jack 300, the first connecting portion 430 can be first connected to the socket body, and then the connecting portion of the plug and its power cord can be snapped into the second card slot 420. Since the width of the second card slot 420 is smaller than the maximum width of the plug, the plug can be fixed by the fixing portion 410. Finally, the second connecting portion 440 is connected to the socket body to fix the claw 400 on the socket body. After the claw 400 is fixed, the fixing of the plug can be achieved.

[0065] Preferably, as shown in Figure 8 , the end of the first connecting portion 430 is bent inward to form a first bending portion 431. An opening (not shown in the figure) is provided on one side of the socket body close to the first connecting portion 430. The first bending portion 431 can be inserted into the opening. Thus, the detachable connection between the first connecting portion 430 and the socket body can be achieved by inserting the first bending portion 431 into the opening.

[0066] Preferably, as shown in Figure 1 and Figure 2As shown, the fixing structure further includes a retractable stop bar 500, which is detachably connected to the socket body. The end of the second connecting portion 440 is bent outward to form a second bent portion 441. The stop bar 500 is located on the second bent portion 441 and connected to the socket body, and the second connecting portion 440 is located between the stop bar 500 and the socket body. Thus, by providing the stop bar 500 detachably connected to the socket body, the second connecting portion 440 can be disposed between the stop bar 500 and the socket body to achieve a detachable connection between the second bent portion 441 and the socket body, thereby realizing the fixation of the claw 400. In addition, since the stop bar 500 can be retracted, the total length of the stop bar 500 can be adjusted to fix different numbers of claws 400, which is not only more convenient to operate but also more convenient to expand the socket.

[0067] Preferably, as Figure 1 , Figure 2 and Figure 8 shown, a protrusion 442 is provided on the second connecting portion 440 and extends outward. The stop bar 500 is located between the protrusion 442 and the second bent portion 441. Thus, this setting can position the stop bar 500 and improve the stability of the stop bar 500.

[0068] Preferably, as Figure 1 and Figure 2 shown, the stop bar 500 includes a first rod body 510 and a second rod body 520 connected to each other. Both the first rod body 510 and the second rod body 520 are arranged along the axial direction of the socket body, and the second rod body 520 can reciprocate along the axial direction of the first rod body 510. Thus, the total length of the stop bar 500 can be adjusted by moving the second rod body 520, and then the fixation of different numbers of claws 400 can be achieved.

[0069] Preferably, as Figure 1 and Figure 2As shown, one end of the first rod body 510 away from the second rod body 520 is connected to the socket body through a first fastener 610, one end of the first rod body 510 close to the second rod body 520 is connected to the socket body through a second fastener 620, one end of the second rod body 520 close to the first rod body 510 is connected to the first rod body 510 through a third fastener 630, and one end of the second rod body 520 away from the first rod body 510 is connected to the socket body through a fourth fastener 640. Thus, such a setting can more conveniently achieve the detachable connection between the first rod body 510 and the socket body and between the second rod body 520 and the socket body. At the same time, since the first rod body 510 and the second rod body 520 are also detachably connected, the second rod body 520 can reciprocate along the axial direction of the first rod body 510. In addition, such a setting can also further simplify the overall structure of the fixing structure.

[0070] Preferably, the first fastener 610, the second fastener 620, the third fastener 630, and the fourth fastener 640 can all be screws, which can be more convenient for installation and disassembly. To facilitate the installation of the second fastener 620 and the fourth fastener 640, the basic socket 100 can be provided with a first mounting hole 140 that cooperates with the second fastener 620, and the single socket 200 can be provided with a second mounting hole 260 that cooperates with the fourth fastener 640.

[0071] Preferably, one end of the first rod body 510 away from the second rod body 520 can be rotatably connected to the socket body through the first fastener 610. Thus, when it is necessary to pull out the plug, it is not necessary to separate the entire first rod body 510 from the socket body to release the fixation of the claw 400. Instead, the end of the first rod body 510 close to the second rod body 520 and the end of the second rod body 520 away from the first rod body 510 can be detached from the socket body, and the first rod body 510 and the second rod body 520 can be rotated to rotate around the other end, thereby releasing the fixation of the claw 400 and further releasing the fixation of the plug.

[0072] Preferably, as Figure 1 and Figure 2As shown, a sliding hole 521 is provided along the axial direction of the second rod body 520. One end of the third fastener 630 can pass through the sliding hole 521 and be connected to the first rod body 510, and the outer diameter of the other end of the third fastener 630 is greater than the width of the sliding hole 521 and abuts against the second rod body 520. Thus, by providing the sliding hole 521 on the second rod body 520, and one end of the third fastener 630 can pass through the sliding hole 521 and be connected to the first rod body 510, the total length of the blocking rod 500 can be adjusted by changing the relative position of the third fastener 630 on the sliding hole 521, which is more convenient for operation. As Figure 1 and Figure 2 shown, if it is necessary to continue adding a single socket 200 and a claw 400 needs to be added to the newly added single socket 200, the fourth fastener 640 can be unscrewed at this time so that the end of the second rod body 520 away from the first rod body 510 is separated from the socket body, and the third fastener 630 can be loosened so that the second rod body 520 can slide to the right along the axial direction of the first rod body 510 to increase the total length of the blocking rod 500. When the second rod body 520 is adjusted to a suitable position, the fourth fastener 640 is installed in the second mounting hole 260 on the newly added single socket 200 and the third fastener 630 is tightened, so that the claw 400 can be fixed by the blocking rod 500. Similarly, when it is necessary to remove a claw 400 to pull out the plug, the fourth fastener 640 can be unscrewed so that the end of the second rod body 520 away from the first rod body 510 is separated from the socket body, and the third fastener 630 can be loosened so that the second rod body 520 can slide to the left along the axial direction of the first rod body 510 to shorten the total length of the blocking rod 500. When the second rod body 520 is adjusted to a suitable position (when the second rod body 520 is separated from the position of the claw 400 to be removed), the claw 400 can be removed.

[0073] In summary, compared with the prior art, the expandable socket with a plug fixing structure provided by the present invention has the following advantages: Since the socket body of the expandable socket provided by the present invention includes a basic socket and at least one single socket; the connection between the basic socket and the adjacent single socket and between any two adjacent single sockets is detachable; both the basic socket and the single socket are provided with at least one set of jacks, so that according to specific usage requirements, several single sockets can be connected to the basic socket, thereby realizing the expansion of the socket, effectively solving the problem of inconvenient use caused by the fact that most sockets in the prior art are integrally designed and the number of jacks is fixed. In addition, since a fixing structure including at least two claws for fixing the plug on the jack is installed on the socket body, the plug can be fixed on the jack of the socket through the fixing structure, effectively preventing the plug from being accidentally pulled out of the socket. Additionally, since the connection between the claw and the socket body is detachable, the corresponding number of claws can be selected according to the number of jacks on the socket body to more conveniently achieve the purpose of fixing the plug on the jack.
