The rectangular rod 312 is placed. When using the plug converter, the protrusion 33 on one side of the outer surface of the rectangular frame 37 can be first put on the outer surface of the three first threaded rods 32 on the outer surface of the positioning block 31, and then the plug pin that needs to be converted can be inserted into the inside of the slot 6. At this time, the part of the plug will be located inside the rectangular frame 37. The second threaded rod 39 is rotated by hand on the inner wall of the rectangular frame 37, so that the two rings 311 on the outer surface of the second threaded rod 39 move on the outer surface of the second threaded rod 39, driving the outer surface of the rectangular rod 312 to move away from the end of the ring 311 on the inner wall of the rectangular groove 38 to adjust the position of the two rectangular rods 312, so that the two rectangular rods 312 move in the same direction, press on the outer surface of the plug and fix it, so as to prevent the pin from falling off from the inside of the slot 6 as much as possible.

[0032] Reference Figure 1 , Figure 2 and Figure 6 In this embodiment, three positioning holes 34 are formed on the outer surface of the protrusion 33, and a threaded ring 35 is threadedly connected to the outer surface of the first threaded rod 32. The three positioning holes 34 on the outer surface of the protrusion 33 are sleeved on the outer surface of the first threaded rod 32, and then the threaded ring 35 is sleeved on the outer surface of the first threaded rod 32 and the threaded ring 35 is rotated so that one side of the outer surface of the threaded ring 35 is pressed against the outer surface of the protrusion 33. The position between the protrusion 33 and the positioning block 31 can be further fixed, and three elastic ropes 36 are fixedly connected to the top end of the outer surface of the protrusion 33. One end of the outer surface of the three elastic ropes 36 is fixedly connected to the top end of the outer surface of the threaded ring 35. By setting the elastic rope 36, the threaded ring 35 can be always fixed to one side of the top end of the outer surface of the protrusion 33 to prevent the threaded ring 35 from falling off and being lost, and it is convenient to use.

[0033] Reference Figure 1 , Figure 2 and Figure 6In this embodiment, the top of the outer surface of the second threaded rod 39 is fixedly connected to a cylindrical block 310, and the outer surface of the cylindrical block 310 is provided with a plurality of protrusions. By pushing the cylindrical block 310 to rotate at the protrusions, the second threaded rod 39 can be more conveniently controlled to rotate without slipping. The inner wall of the rectangular frame 37 is fixedly connected to a cylindrical rod 315 on the side away from the second threaded rod 39. The inner wall of the rectangular rod 312 slides on the outer surface of the cylindrical rod 315 on the side away from the ring 311. During the movement of the rectangular rod 312, one side of the inner wall will slide on the outer surface of the cylindrical rod 315. 15 The angles of the left and right sides of the rectangular rod 312 are fixed to avoid the angle of the rectangular rod 312 from being deflected as much as possible. The outer surface of the rectangular rod 312 is fixedly connected to the side away from the ring 311. The outer surface of the T-shaped block 314 slides on the outer surface of the rectangular frame 37 and the inner wall of the rectangular groove 38. When the rectangular rod 312 moves, the outer surface of the T-shaped block 314 slides on the outer surface of the rectangular frame 37 and the inner wall of the rectangular groove 38 to fix the angle between the rectangular rod 312 and the rectangular frame 37 to increase the stability of the rectangular rod 312 when moving.

[0034] Reference Figure 1 , Figure 2 and Figure 6 In this embodiment: a plurality of ridges 313 are fixedly connected to one side of the outer surface of the rectangular rod 312, and the ridges 313 are rubber strips. By providing the rubber ridges 313, the friction force when the outer surface of the rectangular rod 312 is pressed against the outer surface of the plug can be further increased, so that the rectangular rod 312 can fix the position of the plug more stably and is not easy to slide.

[0035] Working principle: When using the plug converter, first, the three positioning holes 34 on the outer surface of the protrusion 33 on one side of the outer surface of the rectangular frame 37 are put on the outer surfaces of the three first threaded rods 32 on the outer surface of the positioning block 31, and then the three threaded rings 35 fixed by the elastic rope 36 on the top of the outer surface of the protrusion 33 are put on the outer surface of the first threaded rod 32, and then the threaded rings 35 are rotated to make the threaded rings 35 move downward on the outer surface of the first threaded rod 32 and press against the outer surface of the protrusion 33 to fix the relative positions between the rectangular frame 37 and the positioning block 31 and the upper shell 1, and then the plug to be converted is put on. The first plug pin is inserted into the slot 6. At this time, the plug part will be located inside the rectangular frame 37. The cylindrical block 310 is rotated at the protrusion to control the second threaded rod 39 to rotate on the inner wall of the rectangular frame 37, so that the two rings 311 on the outer surface of the second threaded rod 39 move on the outer surface of the second threaded rod 39, driving the outer surface of the rectangular rod 312 away from the end of the ring 311 to slide on the inner wall of the rectangular groove 38 to adjust the position of the two rectangular rods 312, so that the two rectangular rods 312 move in the same direction, press against the outer surface of the plug and fix it, so as to avoid the pin from coming out of the slot 6 as much as possible. The plurality of rubber convex strips 313 on one side of the outer surface of the rectangular rod 312 can further increase the friction force when the outer surface of the rectangular rod 312 is pressed against the outer surface of the plug, making the rectangular rod 312 more stable in fixing the position of the plug and less likely to slide. During the movement of the rectangular rod 312, one side of the inner wall will slide on the outer surface of the cylindrical rod 315. The cylindrical rod 315 fixes the angles of the left and right sides of the rectangular rod 312 to avoid the angle of the rectangular rod 312 from being deflected as much as possible. At the same time, the T-shaped block 314 on the side of the outer surface of the rectangular rod 312 away from the ring 311 will The outer surface of the rectangular frame 37 and the inner wall of the rectangular groove 38 slide to fix the angle between the rectangular rod 312 and the rectangular frame 37 to increase the stability of the rectangular rod 312 when moving. Finally, a pin is inserted into the circular hole 24 on the outer surface of the grounding clamp 23 through the card slot 25, and the pin is connected to the grounding connecting strip 21 inside the cylindrical tube 22 on the outer surface of the grounding clamp 23 through the grounding clamp 23 to realize the connection between the inner core 5 and the ground wire, and then the three pins at the bottom end of the outer surface of the lower shell 4 are inserted into the inside of the socket for use. If there are only two holes on the surface of the socket, the pin at the circular hole 24 can be pulled out.
