Thereby through interior ground terminal connection power connecting wire and bolt for connect the fastening more and later stage maintenance get up also more convenient.
Furthermore, an inwards concave threaded hole is formed in the third internal grounding terminal, and an external thread is arranged at the joint of the third bolt and the third internal grounding terminal. Thereby, the third bolt can be detachably connected with the ground wire through threaded connection.
Furthermore, a sealing cover is arranged on the side wall of the inner side of the shell and close to the slot, and a buckle is arranged on the sealing cover. Therefore, the third bolt can be placed in the slot hole after being pulled out, and the sealing cover is covered to ensure that the third bolt is stored in the slot hole and cannot fall out.
Furthermore, the diameter of the slotted hole is larger than the width of the third bolt, and the depth of the slotted hole is larger than the length of the third bolt. Thereby enabling the third pin to be stored in the slot.
Furthermore, the shell is provided with an anti-skid groove close to the input end of the power connecting line. Therefore, the friction force between the hand and the plug can be increased when the plug is plugged and unplugged.
Compared with the prior art, the utility model has the advantages of:
the utility model relates to a portable dual-purpose functional plug, which comprises a housin, the casing on be provided with power connecting wire, bolt, plastics inner tower, shell fragment and slotted hole, power connecting wire divide into live wire, zero line and ground wire, the bolt divide into first bolt, second bolt and third bolt, first bolt connection the live wire, second bolt connection the zero line, third bolt detachable connect the ground wire. Adopt this kind of portable dual-purpose function plug simple structure, convenient to use, the practicality is strong, can dismantle through the third bolt of connecting the ground wire and store in the slotted hole in the casing, has realized that the plug can alternate the dual-purpose function that three were inserted and two were inserted.

FIG. 2 is a side cross-sectional view of the present invention;
fig. 3 is a schematic view of a third plug according to the present invention.
Detailed Description
As shown in fig. 1-3, the portable dual-purpose functional plug comprises a housing 1, wherein a power connection line, a plug pin, a plastic inner frame 2, a spring plate 3 and a slot 4 are arranged on the housing 1, the power connection line is connected with the plug pin, the tail end of the plug pin is fixed on the plastic inner frame 2, the spring plate 3 is fixedly arranged on two sides of the plastic inner frame 2, the slot 4 is positioned on the inner side of the housing 1 and penetrates through the plastic inner frame 2, the power connection line is divided into a live wire 5, a zero wire 6 and a ground wire 7, the plug pin is divided into a first plug pin 8, a second plug pin 9 and a third plug pin 10, the first plug pin 8 is connected with the live wire 5, the second plug pin 9 is connected with the zero wire 6, and the third plug pin 10 is detachably connected with the ground wire 7. The power connecting line with the bolt junction be equipped with interior ground terminal, interior ground terminal divide into first interior ground terminal 11, second interior ground terminal 12 and third interior ground terminal 13, first interior ground terminal 11 fixed mounting in the junction of first bolt 8 and live wire 5, second interior ground terminal 12 fixed mounting in the junction of second bolt 9 with zero line 6, third interior ground terminal 13 fixed mounting in the junction of third bolt 10 with ground wire 7. Thereby through interior ground terminal connection power connecting wire and bolt for connect the fastening and also more convenient that later stage maintenance gets up. The third inner grounding terminal 13 is internally provided with a concave threaded hole, and the joint of the third bolt 10 and the third inner grounding terminal 13 is provided with an external thread 14. It is achieved thereby that said third plug 10 can be screwed and detachably connected to said earth wire 7. And a sealing cover 15 is arranged on the side wall of the inner side of the shell 1 and close to the slotted hole 4, and a buckle is arranged on the sealing cover. Therefore, the third pin 10 can be put into the slot 4 after being pulled out, and the third pin 10 can not fall out when being stored in the slot 4 by covering the cover. The diameter of the slotted hole 4 is larger than the width of the third bolt 10, and the depth of the slotted hole 4 is larger than the length of the third bolt 10. So that the third pin 10 can be stored in the slot 4. The shell 1 is also provided with an anti-skid groove 16 near the input end of the power connecting line. Therefore, the friction force between the hand and the plug can be increased when the plug is plugged and unplugged.
When the portable dual-purpose functional plug is used specifically, the portable dual-purpose functional plug is connected with an electric appliance to be used, when the electric appliance is required to be operated and inserted, when the socket only has two-hole plugs, the third plug pin 10 of the portable dual-purpose functional plug can be unscrewed anticlockwise, the sealing cover 15 is opened, the pulled third plug pin 10 is stored in the slotted hole 4, then the sealing cover 15 is covered, and the third plug pin 10 stored in the slotted hole 4 is prevented from falling off when the portable dual-purpose functional plug is inserted into the socket through clamping of a buckle on the sealing cover 15, so that the plug capable of being converted into the two-hole plug is realized; conversely, when meetting the socket and having three hole plugs, can take out the interior third bolt 10 of storing in slotted hole 4, be equipped with indent screw hole threaded connection in external screw thread through third bolt 10 and the third in ground terminal 13 and screw, realized becoming three hole plugs by two hole plugs, by third bolt 10 connect ground wire 7 for electrical apparatus has the ground connection effect at the in-process of operation, and is safer.
