Title: Rotational outlet-socket

Description:
BACKGROUND 
     Technical Field 
     The invention relates to an outlet-socket, and in particular, to a rotational outlet-socket capable of rotating in a plurality of angles, to avoid a problem of insertion of a plurality of plugs being affected by a limitation on a plug shape. 
     Related Art 
     Electricity is indispensable in life in an era of science and technology. To satisfy various requirements for obtaining electricity, power supply outlet-sockets cannot be installed at any place inside a building. As the old gives place to the new in electrical appliance devices, a growing number of household electrical appliances become necessary to life, but the supply of outlet-sockets being capable of providing electricity through insertion of plugs falls short of the demand. Therefore, connecting an extra extension outlet-socket with a plurality of jacks to the mains is a most basic solution. 
     However, jack directions for a conventional extension outlet-socket are all the same. Usually, a plurality of jacks of the extension outlet-socket can all be effectively used, so that a plurality of plugs can all be simultaneously inserted in the jacks of the extension outlet-socket. However, in recent years, plug appearance styles are diversified based on brands, and in addition, some plugs have rectifier transformers, to transform AC electricity of the mains power supply into DC electricity satisfying use specifications. Therefore, the size and the shape of a plug affect use space of a neighboring outlet-socket. 
     Therefore, if a plug having a rectifier transformer or having a relatively large size is used, after the plug is inserted into an extension outlet-socket, the rectifier transformer of the plug or a plug shell of the plug covers a jack of another neighboring outlet-socket. Consequently, a plug or a rectifier transformer of another electrical appliance cannot be inserted into the covered jack, thereby reducing a utilization ratio of the extension outlet-socket. 
     In addition, electrical appliances inserted into a same extension outlet-socket do not have a same plug direction, and electrical appliances in various indoor ranges may be inserted into the same extension outlet-socket. If a plug direction of an electrical appliance is different from a direction of a jack of the outlet-socket, a plug of the electrical appliance needs to be twisted or bent to be smoothly inserted into the jack. Long-time use easily breaks a twisted or bent wire, causing a broken circuit or an electrical fire, and leading to a hazard. This is really a safety problem in electricity use. 
     SUMMARY 
     In view of this, a main objective of the invention is to provide a rotational outlet-socket that can rotate in an angle, to match sizes and directions of different electrical appliance plugs, so that an extra extension outlet-socket connected to the mains can achieve an optimal utilization ratio. 
     To achieve the foregoing objective, the invention relates to a rotational outlet-socket, being mainly an outlet-socket group comprising at least two outlet-socket units connected in series, and each outlet-socket unit being capable of separately performing rotation in a plurality of angles, wherein an electric conduction member group is disposed in each outlet-socket unit, each electric conduction member group comprises a first electric conduction rod, a second electric conduction rod, and a ground wire electric conduction rod, a first clamping portion is disposed on the first electric conduction rod, a second clamping portion is disposed on the second electric conduction rod, a ground wire clamping portion is disposed on the ground wire electric conduction rod, and the ground wire clamping portion is pivotally connected to and pivots around the ground wire electric conduction rod through a pivotal connection portion by using a pivotal connection piece. 
     Each outlet-socket unit comprises an upper cover comprising a jack group and a lower cover comprising an accommodation groove, and the accommodation groove is in a concave-arc shape, and is used for accommodating the electric conduction member group. 
     The outlet-socket group comprises a fixing seat, the fixing seat comprises a plurality of spacing rings separating each outlet-socket unit, and a plurality of embedding slot portions accommodated in the outlet-socket unit to buckle each electric conduction member group. 
     A rotation axis of the pivotal connection portion in each electric conduction member group is between the first clamping portion and the second clamping portion, the ground wire clamping portion pivots around the rotation axis when the outlet-socket unit rotates, and the first clamping portion, the second clamping portion, and the ground wire electric conduction rod do not rotate along with the outlet-socket unit. 
     The rotational outlet-socket comprises a base, used for accommodating the outlet-socket group. 
     Switch units corresponding to the number of the at least two outlet-socket units on the outlet-socket group are disposed on the base. 
     A main switch controlling a power supply of the outlet-socket group is disposed on the base. 
     The rotational outlet-socket is connected to the mains through a power line. 
     In this way, an outlet-socket unit pivots in a plurality of angles. When the size of a plug of an electrical appliance is excessively large or an electrical appliance direction is different from a placement direction of a rotational outlet-socket, an angle of each outlet-socket unit in an outlet-socket group may be adjusted, to prevent a neighboring outlet-socket unit having an inserted plug with a relatively large size from being covered, and each outlet-socket unit can rotate based on a direction of the plug of the electrical appliance, to prevent a wire from being twisted and bent, so that a move convenient external extension outlet-socket with a better utilization ratio is provided.

     DETAILED DESCRIPTION 
     Detailed content and technologies of the invention are further described herein in the following by using an embodiment. However, it should be understood that, such an embodiment is only used as an example for description, and should not be construed as a limitation to implementation of the invention. 
     Refer to  FIG. 1 ,  FIG. 2 ,  FIG. 3 ,  FIG. 4 , and  FIG. 5 . A rotational outlet-socket is mainly an outlet-socket group  1000  including at least two outlet-socket units  100  connected in series. Five outlet-socket units  100  connected in series are used as a best embodiment in this application. Each outlet-socket unit  100  is capable of separately performing rotation in a plurality of angles, where an electric conduction member group  200  is disposed in each outlet-socket unit  100 , each electric conduction member group  200  includes a first electric conduction rod  210 , a second electric conduction rod  220 , and a ground wire electric conduction rod  230 , a first clamping portion  211  is disposed on the first electric conduction rod  210 , a second clamping portion  221  is disposed on the second electric conduction rod  220 , a ground wire clamping portion  231  is disposed on the ground wire electric conduction rod  230 , and the ground wire clamping portion  231  is pivotally connected to and pivots around the ground wire electric conduction rod  230  through a pivotal connection portion  233  by using a pivotal connection piece  232 . 
     Each outlet-socket unit  100  includes an upper cover  110  including a jack group  111  and a lower cover  120  including an accommodation groove  121 , and the accommodation groove  121  is in a concave-arc shape, and is used for accommodating the electric conduction member group  200 . Further, the outlet-socket group  1000  includes a fixing seat  300 , the fixing seat  300  includes a plurality of spacing rings  320  separating each outlet-socket unit  100 , and a plurality of embedding slot portions  310  accommodated in the outlet-socket unit  100  to buckle each electric conduction member group  200 , so that each outlet-socket unit  100  can separately rotate in different angles, and is not linked to each other. 
     A rotation axis  240  of the pivotal connection portion  233  in each electric conduction member group  200  is between the first clamping portion  211  and the second clamping portion  221 , the ground wire clamping portion  231  pivots around the rotation axis  240  when the outlet-socket unit  100  rotates, and the first clamping portion  211 , the second clamping portion  221 , and the ground wire electric conduction rod  230  do not rotate along with the outlet-socket unit  100 . 
     During implementation, also refer to  FIG. 6 ,  FIG. 7 ,  FIG. 8 , and  FIG. 9 . In the figures, two outlet-socket units  100  are connected in series, to show a difference before and after rotation. In the figures, a pivoting angle of the pivotal connection portion  233  is in a range of 0 degrees to 90 degrees, that is, a direction of the jack group  111  on the outlet-socket unit  100  can be changed from upward to sideward through rotation. 
     When the outlet-socket unit  100  is in a normal state without rotation, the jack group  111  on the outlet-socket unit  100  faces upward. The first conduction pole piece clamp  211  and the second conduction pole piece clamp  221  in the outlet-socket unit  100  are fastened in the embedding slot portion  310  of the fixing seat  300 , and an opening clamped by the ground wire clamping portion  231  and the jack group  111  also face upward. When the outlet-socket unit  100  starts to rotate, the first conduction pole piece clamp  211  and the second conduction pole piece clamp  221  are still fastened in the embedding slot portion  310  of the fixing seat  300 , and kept in original locations and original directions together with the fixing seat  300  without shifting. Only the pivotal connection piece  232  extending from the ground wire clamping portion  231  drives, through the pivotal connection portion  233 , the ground wire clamping portion  231  to rotate in different angle ranges around the rotation axis  240  between the first conduction pole piece clamp  211  and the second conduction pole piece clamp  221 . When a plug  400  is inserted into the jack group  111  on the outlet-socket unit  100 , the ground wire clamping portion  231  can drive, through the pivotal connection portion  233 , a ground wire pole piece  410  of the plug  400  inserted therein to pivot. When the plug  400  is inserted into the jack group  111 , a live wire pole piece and a neutral wire pole piece  420  on the plug  400  are respectively inserted into the first conduction pole piece clamp  211  and the second conduction pole piece clamp  221 . When the ground wire clamping portion  231  drives the plug  400  to pivot, the first conduction pole piece clamp  211  and the second conduction pole piece clamp  221  do not shift, but the live wire pole piece and the neutral wire pole piece  420  inserted therein rotate along with the plug  400 , and rotate around the rotation axis  240  in the first conduction pole piece clamp  211  and the second conduction pole piece clamp  221 . 
     Refer to  FIG. 10 . The foregoing content indicates that, when the outlet-socket unit  100  rotates, the fixing seat  300 , and the first electric conduction rod  210  and the second electric conduction rod  220  buckled in the embedding slot portion  310  do not rotate along, and only the ground wire clamping portion  231  of the electric conduction member group  200  rotates around the rotation axis  240  by using the pivotal connection portion  233 . Therefore, when the outlet-socket unit  100  is in a state without rotation, the jack group  111  on the outlet-socket unit  100  faces upward. When the outlet-socket unit  100  starts to rotate, a direction of the jack group  111  on the upper cover  110  is changed to sideward, and each outlet-socket unit  100  on the outlet-socket group  1000  can separately present a different direction through rotation, without being restricted by a neighboring outlet-socket unit  100 , so that different electrical appliance plugs  400  can be inserted into the jack group  111  without being limited by directions. 
     Also refer to  FIG. 11  and  FIG. 12 . The rotational outlet-socket includes a base  500 , used for accommodating the outlet-socket group  1000 . The base  500  is connected to the mains through a power line  530 . A main switch  510  controlling a power supply of the outlet-socket group is disposed on the base  500 . A plurality of switch units  520  corresponding to the number of these outlet-socket units  100  on the outlet-socket group  1000  is disposed on the base  500 . The power supply of the outlet-socket group  1000  is switched on or off through the main switch  510 , and current supply to each outlet-socket unit  100  is controlled by using different switch units  520 . 
     In this way, the outlet-socket unit  100  can rotate in different angles in a rotation range, without being limited by the size of a neighboring plug  400 . Only the outlet-socket unit  100  needs to be rotated by an angle, to avoid a problem of inconvenient insertion caused by the excessively large plug  400  shielding the neighboring jack group  111  and a direction of the plug  400  being different from a placement direction of the outlet-socket group  1000 . 
     The invention is already described in the foregoing by using the preferred embodiment, but a person skilled in the art should understand that, the embodiment is only used for describing the invention and should not be construed as a limitation to the scope of the invention. It should be noted that, all variations and replacements equivalent to the embodiment should fall within the scope of the invention. Therefore, the protection scope of the invention should be subjected to that defined in the claims.
