RELATED APPLICATIONS 
     This application is a Continuation of U.S. patent application Ser. No. 15/649,100 filed on Jul. 13, 2017, which claims the benefit of priority of U.S. Provisional Patent Application No. 62/409,135 filed on Oct. 17, 2016. The contents of the above applications are all incorporated by reference as if fully set forth herein in their entirety. 
    
    
     FIELD AND BACKGROUND OF THE INVENTION 
     This disclosure relates to a modular replaceable socket device, and more particularly to a modular replaceable socket device widely utilized in various types of jacks. 
     The sockets for domestic and commercial electricity are generally categorized into types utilized in 110-120V or 220-240V. The 110V-120V socket is further divided into a two-hole type and a three-hole type. Therefore, the type of the sockets has to be chosen in advance before installing or purchasing sockets. For example, the three-hole type sockets utilized to 220-240V should be installed nearby where the air-conditioner will be set, and the two-hope type or the three-hole type sockets utilized in 110-120V should be installed nearby where the electronic appliances will be set. In addition, not only should the voltage should be considered, the types of sockets should be noted as well in case, for example, the three-pin plug will not fit the two-hole sockets. Furthermore, the plugs have to be inserted in specific direction, in this situation, the power cable will be curved and the insulation layer of the power cable may rupture, resulting in leakage of electricity or a short circuit. 
     The electronic appliances which are purchased overseas cannot be used anymore since the sockets do not fit the plugs. Although there are adapters available on the markets, however, it&#39;s inconvenient to attach an adapter on the plug, and occupy more space and sometimes cause danger due to the low-quality of the adapters. 
     Furthermore, the Power Line Communication (PLC) technologies allow the network data to be transmitted by the power cables. The PLC technologies requires modems installed on sockets or network bridge with PLC functions, however it&#39;s inconvenient to attach an adapter on the plug, and occupy more space as well. 
     SUMMARY OF THE INVENTION 
     The purpose of the present disclosure is to provide a modular replaceable socket device which can choose proper adapters set on a base according the specification or the type of plug.

     Please refer to  FIG. 7  and  FIG. 8 , which are exploded views of the modular replaceable socket device in  FIG. 1  and  FIG. 2 . There is a jack  22  disposed on a top of the adapter  20  and contacts  24  disposed on a bottom of the adapter  20 . The base  30  includes one or more sockets  34 . 
     Please refer to  FIG. 9 , which illustrates an enlarged view of the contacts  24  and the sockets  34 . There is a jack  22  disposed on a top of the adapter  20  and contacts  24  disposed on a bottom of the adapter  20 . There is an adapting interface  40  disposed on the socket  34 . Each of the sockets  34  includes a bottom surface  341  and a surrounded sidewall  342  to form only one opening. 
     Please refer to  FIG. 10 , which shows the structure of the contact  24  after turning the adapters  20  over. The structures of the adapting interface  40  correspond to the contacts  24 . The details of the contacts  24  and the adapting interface  40  are as shown in  FIG. 11 . Please refer to  FIG. 11 , there are POGO PINs  400 A- 400 P disposed on the adapting interface  40 , and there are flat connectors  240 A- 240 P, which correspond to the POGO PINs  400 A- 400 P, disposed on the contacts  24 . The POGO PIN  400 A connects to the flat connector  240 A. The POGO PIN  400 B connects to the flat connector  240 B. The POGO PIN  400 P connects to the flat connector  240 P. The structures of the contacts  24  and the adapting interface  40  when they are connecting to each other are shown in  FIG. 12 . The POGO PINs  400 A- 400 P connect to the flat connectors  240 A- 240 P to make the power be transmitted from the base  30  to the jack  22 . 
     Please refer to  FIG. 13 , which illustrates the cross-section view of the POGO PINs  400 A- 400 P and the flat connectors  240 A- 240 P when they are connected to each other. The adapter  20  couples to the socket  34  via the contacts  24  and the adapting interface  40  so that the power can be transmitted from the base  30  to the jack  22 . In the preferable embodiment, the height of the POGO PIN  400 A- 400 B is not beyond the horizontal line of the top plane of the socket  34 . 
     In addition, there is still a first magnetic part  26  located on the adapter  20 , and a second magnetic part  46  located on the adapting interface  40  where the first magnetic part  26  magnetically connects to the second magnetic part  46 . The first magnetic part  26  and the second magnetic part  46  can connect to each other at any time, or connect to each other only if there is power existing. For example, first magnetic part  26  located on the adapter  20  could be an electromagnet. When the adapter  20  is set on the socket  34 , the first magnetic part  26  connects to the external power via base  30  so the first magnetic part  26  possess magnetism that allows the first magnetic part  26  to magnetically connect to the second magnetic part  46 . In another embodiment, the first magnetic part  26  is an electromagnet which does not possess magnetism since the power has not been conducted when the adapter  20  is set on the socket  34 . After the plug of an electronic device is inserted into the jack  22 , the power will be supplied to the electronic device and the first magnetic part  26  to make the first magnetic part  26  possess magnetism so that the first magnetic part  26  can magnetically connect to the second magnetic part  46 . The adapter  20  could be fixed securely on the socket  34  through the connection between the first magnetic part  26  and the second magnetic part  46 , thus that modular replaceable socket device will be safer. The first magnetic part  26  being an electromagnet is just one of the embodiments. The second magnetic part  46  can be an electromagnet as well. Moreover, the present disclosure does not limit to use electromagnets to get the magnetic connection. Any materials which can make the first magnetic part  26  and the second magnetic part  46  magnetically connect to each other fall into the scope of the present disclosure. 
     The potential of each contacting point of the contacts  24  and the adapting interface  40  are different, which may divide into the live lines, neutral lines or earth lines (ground lines). The contacting point of the contact  24  and the adapting interface  40  could be divided into several groups according to the types of the jack  22 . For example, the adapting interface  40  can be grouped into the first potential and the second potential which may correspond to live lines and neutral lines. For another example, the adapting interface  40  can be grouped into the first potential, the second potential, and the third potential which may represent to the live lines, neutral lines, and earth (ground) lines. The structures of the adapter  20  of present disclosure could be designed to be non-directional. The flat connectors corresponding to the POGO PINs mentioned in  FIG. 9 - FIG. 13  could be grouped into two groups, live lines and neutral lines, according to the potential. As shown in  FIG. 14 , take flat connectors  240 A- 240 P as example, the contacting point of the flat connectors and the POGO PINs could be divided into X group and Y group. And the arrangement of the group makes the contacting points stay in the same order no matter how the adapter  20  turns. 
     The 16 contacting points can further divide into three groups of live lines, neutral lines, or earth (ground) lines. As shown in  FIG. 15 , the 16 contacting points are divided into three groups: X, Y, and Z. The arrangement make the order of the 16 contacting points remain the same no matter how the adapter  20  turns. Therefore, the adapter  20  can be set on the socket  34  regardless the direction so that the adapter  20  could be turned into any direction as wished. 
     Please refer to  FIG. 16  which shows the second embodiment. It is worth mentioning that the POGO PINs cannot only be disposed on the adapting interface  40 , but can also be disposed on the contacts  24 . In the meanwhile, there are corresponding flat connectors disposed on the adapting interface  40 . In this embodiment, the contacts  24  include POGO PINs  241 A- 241 P, and the adapting interface  40  includes the flat connectors  401 A- 401 P. The POGO PIN  241 A connects to the flat connector  401 A. The POGO PIN  241 B connects to the flat connector  401 B. The POGO PIN  241 P connects to the flat connector  401 P. The cross-section view of the POGO PINs and the flat connectors after they connect to each other can take  FIG. 13  as reference. The only difference between the second embodiment and the first embodiment is that the flat connectors are located on the socket  34  and the POGO PINs are located on the adapter  20 . Furthermore, in the preferred embodiment, the heights of the POGO PINs located on the adapting interface  40  are not beyond the horizontal line of the top plan of the socket  34  when the flat connectors located on the adapter  20 .

The cross-section view of the POGO PINs and the flat connectors after they connect to each other can take  FIG. 18  as reference. The only difference between the third embodiment and  FIG. 18  is that the flat connectors  402 A- 402 I are located on the socket  34  and the POGO PINs  242 A- 242 I are located on the adapter  20 .  FIG. 18  illustrates the cross-section view of the POGO PINs  242 A- 242 I and the flat connectors  402 A- 402 I after they connect to each other. The adapter  20  couples to the socket  34  through the contacts  24  and the adapting interface  40  so that the power can be transmitted from base  30  to jack  22 . A top of the adapting interface  40  is lower than the bottom surface  341  of the socket  34  and the surrounded sidewall of the sockets  34  surrounds the adapting interface  40 . 
     In the fourth embodiment, the POGO PIN can be located on the adapting interface  40  and the flat connectors corresponding to the POGO PINs can be located on adapter  20 . The cross-section view of the forth embodiment can take  FIG. 13  as reference. Furthermore, in the preferred embodiment, the heights of the POGO PINs located on the adapting interface  40  are not beyond the top horizontal line of the top plan of the socket  34  when the flat connectors located on the adapter  20 . 
     The contacting points of the third embodiment and the forth embodiment can be grouped as the first and the second embodiment. Please refer to  FIG. 19 , take the flat connectors  402 A- 402 I as example, the flat connectors can be divide into X group and Y group so that the arrangement of X and Y will remain the same no matter how the adapting interface  40  turns. Or refer to  FIG. 20 , the contacting points of the contacts  24  and the adapting interface  40  could be divided into three groups which represent live lines, neutral lines, and earth (ground) lines. The arrangement as shown in  FIG. 20  makes the order of the X, Y, and Z remain the same so that the adapter  20  can fit the adapting interface  40  no matter how the adapting interface turns. 
     The contacts  24  and the adapting interface  40  of the modular replaceable socket device  10  can also be any type of contact and connector other than POGO PINs and flat connectors, like U-type contacts, square contacts, or circular contacts (not shown), cylindrical connectors, square-column connectors, rectangular-column connectors, circular connectors, or square connectors. The details will be illustrated in following paragraph. 
       FIG. 21  illustrates the structure of the U-type contact including contact clip  62  and fixing part  64 . The contact clip  62  is usually made from metal for coupling to the connectors which have two contact points  622  and  624  with the contact clip  62 . The fixing part  64  is utilized to fix the U-type contacts on the adapters  20  or the sockets  34 . Please continue to  FIG. 22 . 
       FIG. 22  illustrates the fifth embodiment. In the fifth embodiment, the contacts  24  consist of 9 U-type contacts  243 A- 243 I. The adapting interface  40  includes 9 cylindrical connectors which correspond to the U-type contacts  243 A- 243 I. In this embodiment, take the U-type contact  243 C and the cylindrical connector  403 C as an example, the U-type contact  243 C and the cylindrical connector  403 C have two contact points  622 C and  623 C. The distance between the contact points  622 C and  623 C is narrower than the dimension of the cylindrical connector  403 C. In addition, the contact clips of the U-type contact  243 C are flexible so that they can stably couple to the cylindrical connector  403 C. 
     As in the aforesaid embodiments that includes the POGO PINs and the flat connectors, the positions of the U-type contacts and the cylindrical connectors which are located on the contacts  24  and the adapting interface  40  respectively in the fifth embodiment can be switched. As for the sixth embodiment of the present disclosure, please refer to  FIG. 23 . 
     The connectors corresponding to the U-type contacts could also be square-column connectors, besides the cylindrical connectors, as shown in  FIG. 24 .  FIG. 24  illustrates the seventh embodiment. In the seventh embodiment, the contacts  24  consist of U-type contacts  244 A- 244 I. The adapting interface  40  includes square-column connectors  404 A- 404 I corresponding to the U-type contacts  244 A- 244 I. In this embodiment, there are two contacting points between the U-type contacts and the contact clip. Take the U-type contact  244 C and the square-column connector  404 C as an example, the distance between the contact point  622 C and  624 C are narrower than dimension of the square-column  403 C. Therefore, the U-type contact  244 C can couple to the square-column connector  404 C stably since the U-type contact  244 C is flexible. 
     The adapting interface  40  of the eighth embodiment includes U-type contacts, and the contacts  24  are square-column connectors corresponding to the U-type contacts. The structures and the shape of the U-type contacts and the square-column connectors can take the seventh embodiment as a reference. 
     The contacts and the connectors of the fifth, sixth, seven, and eighth embodiments can also have 16 contacting points. The contacting points, no matter if there are 9 or 19 contacting points, can be divided into two or three groups by their potential as shown in  FIGS. 14, 15, 19 and 20 . 
     The openings of the U-type contacts are toward the same direction, however, the openings could be arranged toward different directions in order to make the adapters  20  more stable while installed on the sockets  34 . The ninth embodiment illustrates an example that the U-type contacts are toward different directions as shown in  FIG. 25 . In  FIG. 25 , the contacts consist of 9 U-type contacts  245 A- 245 I which are arranged in three lines. The first line is consisted of  245 A- 245 C, the second line is consisted of  245 D- 245 F, and the third line is consisted of  245 G- 245 I. The U-type contacts  245 D- 245 F in second line are toward to the same direction. The U-type connector  245 A of the first line turns right at 45 degrees relative to the U-type connector  245 D. The U-type connector  245 B turns right at 45 degrees relative to the U-type connector  245 A. (That is, turns right at 90 degrees relative to the  245 E.) The U-type connector  245 C turns right at 45 degrees relative to the U-type connector  245 B. (That is, turns right at 135 degrees relative to the  245 F.) The U-type connector  245 G of the third line turns left at 45 degrees relative to the U-type connector  245 D. The U-type connector  245 H turns left at 45 degrees relative to the U-type connector  245 G. (That is, turns left at 90 degrees relative to the  245 E.) The U-type connector  245 I turns left at 45 degrees relative to the U-type connector  245 H. (That is, turns left at 135 degrees relative to the  245 F.) 
     Please refer to  FIG. 25  and  FIG. 26 . The adapting interface  40  includes 9 rectangular-column connectors  405 A- 405 I corresponding to the U-type contacts  245 A- 245 I in the ninth embodiment. The rectangular-column connectors are arranged in three lines as well. The rectangular-column connectors  405 A- 405 C form the first line. The rectangular-column connectors  405 D- 405 F form the second line. The rectangular-column connectors  405 G- 405 I form the third line. The rectangular-column connectors  405 D and  405 F are arranged in the same direction. The rectangular-column connector  405 E is a square-column connector in this embodiment to make the adapting interface  40  symmetric to both centerline and diagonal so that the sockets  34  and the adapters  20  are non-directional in the present disclosure. However, please refer to  FIG. 26 , any shapes which make the sockets  34  non-directional can be utilized in the rectangular-column connector  405 E of the present disclosure, being a square-column is just one of the examples. The directions of the rectangular-column connectors  405 A- 405 C arranged in the first line are required to correspond to the U-type contacts  245 A- 245 C, therefore, the rectangular-column connector  405 A turns left at 45 degrees relatively to the rectangular-column connectors  405 D. The rectangular-column connectors  405 B turns left at 45 degrees relative to the rectangular-column connectors  405 A. (That is, turns left at 90 degrees relative to  405 D.) The rectangular-column connectors  405 C turns left at 45 degrees relative to the rectangular-column connectors  405 B. (That is, turns left at 135 degrees relative to  405 D.) Similarly, the directions of the rectangular-column connectors  405 G- 405 I arranged in the third line are required to correspond to the U-type contacts  245 G- 245 I, therefore, the rectangular-column connector  405 G turns right at 45 degrees relative to the rectangular-column connectors  405 D. The rectangular-column connectors  405 H turns right at 45 degrees relative to the rectangular-column connectors  405 G. (That is, turns right at 90 degrees relative to  405 D.) The rectangular-column connectors  405 I turns right at 45 degrees relative to the rectangular-column connectors  405 H. (That is, turns right at 135 degrees relative to  405 D.) 
     Please refer to  FIG. 27  which illustrates the structure of the U-type contacts  245 A- 245 I and the rectangular-column connectors  405 A- 405 I after they are connected. Connecting the U-type contact  245 A to the rectangular-column connector  405 A, the U-type contact  245 B to the rectangular-column connector  405 B, the U-type contact  245 C to the rectangular-column connector  405 C in  FIG. 25  can get the structures illustrated in the  FIG. 27 . Similar connections are made between the U-type contacts  245 D- 245 I and the rectangular-column connectors  405 D- 405 I respectively and will not be mentioned herein. The U-type contacts  245 A- 245 I couple to the rectangular-column connectors  405 A- 405 I. Take the U-type contact  245 I and the rectangular-column connector  405 I as an example, there are two contact points  622 I and  624 I between the U-type contact  245 I and the rectangular-column connector  405 I. The distance between  622 I and  624 I is narrower than dimension of the rectangular-column connector  405 I. In the meanwhile, the U-type contact  245 I is flexible, so that the contacts  24  will be stably connected to the adapting interface  40 . In addition, since the directions of the U-type contacts are different, the adapter  20  will fasten onto the socket  34 . 
     Please refer to  FIG. 28 . In the tenth embodiment, the contacts  24  consist of square contacts  246 , and the adapting interface  40  includes the square connectors  406  corresponding to the square contacts  246 . The square contacts  246  include three contact flakes  246 X,  246 Y, and  246 Z. The structure of the contact flake  246 X is similar to the U-type contacts. The contact flake  246 Y surrounding the contact flake  246 X, which is a square-circuit with opening or a closed square-circuit. The contact flake  246 Y includes four contact pins  246 Y 1 ,  246 Y 2 ,  246 Y 3 , and  246 Y 4 . The shape of the contact flake  246 Z is a square-circuit with opening or a closed square-circuit surrounding the contact flake  246 Y. The contact flake  246 Z also includes four contact pins  246 Z 1 ,  246 Z 2 ,  246 Z 3 , and  246 Z 4 . The square connectors  406  include a central pin  406 X and two square ring  406 Y and  406 Z. The square ring  406 Z surrounds the  406 Y. The central pin  406 X is located in the center of the square ring  406 Y and  406 Z. 
       FIG. 29  illustrates the structures of the square contacts  246  and the square connectors  406  after they are connected to each other. The contact flake  246 X couples to the central pin  406 X. The contact flake  246 Y couples to the square ring  406 Y through the contact pins  246 Y 1 ,  246 Y 2 ,  246 Y 3 , and  246 Y 4 . Take the contact pin  246 Y 4  as an example, there is a contact point  626  between contact pin  246 Y 4  and the square ring  406 Y. The contact pin  246 Y 4  can firmly couple to the square ring  406 Y while the square contacts  246  connect to the square connectors  406  since the contact pin  246 Y 4  is flexible. Similarly, the contact pins  246 Y 1 ,  246 Y 2 , and  246 Y 3  can also firmly contact with the square ring  406 Y to make the contact flake  246 Y couple to the square ring  406 Y. 
     The contact flakes  246 Z couple to the square ring  406 Z through the contact pins  246 Z 1 ,  246 Z 3 ,  246 Z 3 , and  246 Z 4  as well. Take the contact pin  246 Z 3  as an example, there is a contact point  628  between the contact pin  246 Z 3  and the square ring  406 Z. The contact flakes  246 Z couple to the square ring  406 Z through the connection between the contact pins  246 Z 1 ,  246 Z 2 ,  246 Z 4 , and the square ring  406 Y as in the aforesaid illustration. 
     The contact flakes  246 X,  246 Y, and  246 Z, and the central pin  406 X, square ring  406 Y, and  406 Z can individually represent different potentials. For example, the contact flake  246 X and the central pin  406 X represent the earth (ground) lines, the contact flake  246 Y and the square ring  406 Y represent the live lines, and the contact flake  246 Z and the square ring  406 Z represent the neutral lines. By following the design of this embodiment, the power can be transmitted from the base  30  to the jack  22  after the adapters  20  are installed on the sockets  34 . 
       FIG. 30  illustrates the eleventh embodiment that the contacts  24  consist of square contacts  247 , and the adapting interface  40  includes circular connectors  407 . The contacts  247  include three contact flakes  247 X,  247 Y, and  247 Z. The shape of the contact flake  247 X is similar to U-type contacts. The contact flake  247 Y surrounding the contact flake  247 X, which is a square-circuit with opening or a closed square-circuit. The contact flake  247 Y includes four contact pins  247 Y 1 ,  247 Y 2 ,  247 Y 3 , and  247 Y 4 . The shape of the contact flake  247 Z is a square-circuit with opening or a closed square-circuit surrounding the contact flake  247 Z. The contact flake  247 Z also includes four contact pins  247 Z 1 ,  247 Z 2 ,  247 Z 3 , and  247 Z 4 . The circular connectors  407  include a central pin  407 X and two circular rings  407 Y and  407 Z. The circular ring  407 Z surrounds the circular ring  407 Y, and the central pin  407 X locates at the center of the circular rings  407 Y and  407 Z. 
       FIG. 31  illustrates the structure of the square contacts  247  and the circular  407  after they are connected to each other. The contact flake  247 X couples to the central pin  407 X. The contact flake  247 Y couples to the circular ring  407 Y through the contact pins  247 Y 1 ,  247 Y 2 ,  247 Y 3 , and  247 Y 4 . Take the contact flake  247 Y 4  as an example, there is a contact point  626  between contact pin  247 Y 4  and the square ring  407 Y. The contact pin  247 Y 4  can firmly couple to the square ring  407 Y while the square contacts  24  connect to the square connectors  407  since the contact pin  247 Y 4  is flexible. Similarly, the contact pins  247 Y 1 ,  247 Y 2 , and  247 Y 3  can also firmly contact with the square ring  407 Y to make the contact flake  247 Y couple to the square ring  407 . 
     The contact flake  247 Z couples to the circular ring  407 Z through the contact pins  247 Z 1 ,  247 Z 2 ,  247 Z 3 , and  247 Z 4 . Take the contact pin  247 Z 3  as an example, there is a contact point  628  between the contact pin  247 Z 3  and the square ring  407 Z. The contact flakes  247 Z couple to the  407 Z through the connection between the contact pins  247 Z 1 ,  247 Z 2 ,  247 Z 4  and the square ring  407 Y as in the aforesaid illustration. This embodiment can transmit the power signals in different potentials as the tenth embodiment. In addition, this embodiment is non-directional so that the adapter  22  can be installed on the sockets  34  in any direction. 
     In the fifth to eleventh embodiments, the U-type contacts and the square contacts cannot exceed the horizontal line of the top plane of the socket  34  when they locate on the adapting interface  40 . The cylindrical connectors, square-column connectors, rectangular-column connectors, square connectors and circular connectors cannot exceed the horizontal line of the top plane of the socket  34  when they locate on the adapting interface  40 . 
     The adapters  20  of the first to eleventh embodiments can be designed as non-directional adapters, or be designed as directional adapters. For example, the U-type contacts could be designed in different directions that require corresponding connectors in specific directions and shapes to match with. Or the contacts  24  and the adapting interface  40  can only connect to each other in a specific direction because of their shapes. (Like rectangle can only fit in two ways.) Or the adapters  20  have a protrusion part which corresponds to the dent on the adapting interface  40 , thus the adapters  20  can be installed on the socket  34  only when the outstanding parts match with the dents. 
     In addition, the base  30  further includes one or more switches. Please refer to  FIG. 1 , there is a vice-switches  320  disposed next to each socket to control the power through the sockets  34 . The base can also have a switch  310  to control the power through the whole base  30 . The switch  310  and the vice-switches  320  can include fuses to make the over-loaded base  30  or sockets  34  become open circuit. 
     The adapters  20  and the adapting interface  40  could further be designed to possess magnetism between the first magnetic part  26  and the second magnetic part  46  when the switch  310  or the vice-switches  320  are switched on. Hence the adapters  20  can be stably installed on the socket  34 . In contrast, the magnetism between the first magnetic part  26  and the second magnetic part  46  will disappear when the switch  310  or the vice-switches  320  are switched off. In this case, the adapters  20  can be removed from the sockets  34 . 
     The modular replaceable socket devices can further have a Power Line Communication (PLC) module which can process a data signal and allow the data signal to be transmitted via the power line. Thus the data signal can be transmitted between electronic devices, other PLC modules, the internet etc. The jack  22  could also be an RJ 45  jack  226  or other jack for the internet, thus the modular replaceable socket devices of present disclosure can also supply data transmission while transmitting power. 
     The jack  22  can be an LED  228  so the adapter  20  can illuminate or show the condition of the sockets. For example, LED  228  can show the load of the modular replaceable socket devices by displaying different colors. Or the LED  228  can show the transmission condition of the modular replaceable socket devices by the different flashing frequency or different colors. 
     The modular replaceable socket devices of present disclosure solve the problems that the convention sockets cannot apply to different types of plugs through the structures of the adapters and the adapting interface. The modular replaceable socket devices can transmit not only power signals, but also data signals. The magnetic connection between the adapters and the sockets can improve the stability between them. And the modular replaceable socket devices of the present disclosure could be designed as directional or non-directional sockets. The separable interface allows the power cable to be separated from the base while the modular replaceable socket devices are not in use. 
     The present disclosure has been described with a preferred embodiment thereof and it is understood that many changes and modifications to the described embodiment can be carried out without departing from the scope and the spirit of the invention that is intended to be limited only by the appended claims.
