Description of the Invention: [Technical Field] The present invention relates to a plug. [Prior Art] A conventional socket is usually provided with a plurality of sets of jacks so that a plurality of plugs are simultaneously inserted thereon for powering Sexual connection m, found in the process of use 'Because the distance between the multiple sets of jacks is usually small, the larger plug usually takes up more space, thus interfering with the adjacent other plugs and sockets The connection is not convenient for the user. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a plug that is convenient for the user to use. A plug includes a housing and a conductive rod disposed in the housing, the housing is provided with a card slot, and the conductive rod includes a pin extending from the card slot and extending from the pin And a wire portion disposed on the wire and adjacent to the pin, the knob portion having a thread for screwing into the card slot. When there is not enough space on the socket to facilitate the plug insertion, the engraving portion can be unscrewed from the slot of the plug so that the length of the conductive rod is exposed to the housing is long enough to be inserted into the socket, thereby For the convenience of users. [Embodiment] Please refer to FIG. 1, which is a perspective view of a plug 10 of a specific embodiment. The plug 10 includes a housing 100 and a conductive rod 20. In the present embodiment, the number of the conductive rods 20 is two. Referring to FIG. 2 , the housing 100 includes an upper housing 200 and a lower housing 201 that is engaged with the upper housing 200 . A fixing hole 214 is defined in a side wall 215 of the lower casing 201. The other side wall 217 opposite to the side wall 215 is provided with a truncated cone-shaped slot 212. The end of the slot 212 away from the fixing hole 214 is larger than the fixed side. One end of the hole 214. The card slot 212 is internally provided with a thread. A stud 216 is formed on the lower casing 201 opposite to the upper casing 200. The upper casing 200 and the lower casing ® body 201 can be fixed together by a fixing member such as a screw. The conductive rod 20 includes a pin 202, a wire 205 in electrical communication with the pin 202, and a knob portion 203 disposed outside the wire 205 and adjacent to the pin 202. The pin 202 can be inserted into a socket of a socket (not shown) to be electrically connected to the socket to allow the electrical product of the connector plug 10 to be connected to the circuit through the pin 202. The wire 205 is made of a soft material and is wound into a loop and accommodated between the upper housing 200 and the lower housing 201. A non-slip portion 207 and a locking portion 209 opposed to the anti-slip portion 207 are protruded from the wire 205. When the wire 205 is fixed in the fixing hole 214 of the casing 100, the locking portion 209 abuts against the outside of the upper casing 200 and the lower casing 201, and the anti-slip portion 207 is located between the upper casing 200 and the lower casing 201. That is, a portion of the wire 205 between the anti-slip portion 207 and the locking portion 209 is fixed in the fixing hole 214 so that the wire 205 does not move relative to the fixing hole 214. The knob portion 203 is also in the shape of a frustum, and its size gradually increases from the direction of the wire 205 to the pin 202. The knob portion 203 has an external thread, and the knob 5 1380536 • the portion 203 is sized to fit the slot 212 for screwing into the slot 212 so that the pin 202 can be in a direction away from or near the housing 100. extend. When the plug 10 is in the unused state, the knob portion 203 is screwed to the slot 212, the anti-slip portion 207 is located between the upper housing 200 and the lower housing 201, and the locking portion 209 abuts against the upper housing 200 and the lower portion. The exterior of the housing 201. As shown in FIG. 3, when there is not enough space on the socket to facilitate the insertion of the plug 10, the knob portion 203 can be unscrewed from the slot 212 of the plug 10 so that the length of the conductive rod 20 is exposed to the housing 100. It is long enough to be inserted into the socket, so that it is convenient for the user to use. It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
