The first positioning rod 6 and the second positioning rod 10 are fixedly provided diagonally on the side of the male plug 1 closest to the female plug 2. The female plug 2 is provided with a positioning hole 7 that matches the first positioning rod 6 and the second positioning rod 10 on the side of the female plug 1 closest to the male plug 1. The first positioning rod 6 and the second positioning rod 10 are slidably connected to the female plug 2 through the positioning hole 7. The first positioning rod 6 and the second positioning rod 10 are both provided with the limiting hole 9 on their outer sides. The female plug 2 is provided with a first sliding rod 14 and the second sliding rod 15 that matches the limiting hole 9. The first sliding rod 14 is slidably connected to the second positioning rod 10 through the limiting hole 9, and the second sliding rod 15 is slidably connected to the first positioning rod 6 through the limiting hole 9.

[0021] In this embodiment, the female plug 2 is provided with a first sliding groove 16 and a second sliding groove 17 that are adapted to the first sliding rod 14 and the second sliding rod 15. The first sliding groove 16 and the second sliding groove 17 are respectively connected to the positioning hole 7. The first sliding rod 14 is slidably connected to the female plug 2 through the first sliding groove 16, and the second sliding rod 15 is slidably connected to the female plug 2 through the second sliding groove 17.

[0022] In this embodiment, when the male plug 1 and the female plug 2 are inserted, the plug block 4, the first positioning rod 6 and the second positioning rod 10 are aligned with the slot 5 and the two positioning holes 7, respectively. When the plug block 4 is engaged inside the slot 5, the first positioning rod 6 and the second positioning rod 10 are simultaneously engaged inside the positioning holes 7. At this time, the limiting hole 9 is connected to the first sliding groove 16 and the second sliding groove 17, respectively. The limiting hole 9 is aligned with the first sliding rod 14 and the second sliding rod 15, respectively. The first sliding rod 14 and the second sliding rod 15 can move and extend into the limiting hole 9 to prevent the first positioning rod 6 and the second positioning rod 10 from moving further, thereby fixing the relative position of the male plug 1 and the female plug 2 and preventing the male plug 1 and the female plug 2 from becoming loose.

[0023] In a preferred embodiment, please refer to Figures 1 to 4The female plug 2 is provided with a drive mechanism at one end near the male plug 1. The drive mechanism consists of a knob 8, a threaded rod 11, a connecting plate 12, and a mounting groove 13. The female plug 2 is provided with a knob 8 on the outside. The threaded rod 11 is fixedly provided on the side of the knob 8. The other end of the threaded rod 11 is rotatably connected to the connecting plate 12 through a bearing. The female plug 2 is provided with a mounting groove 13 that is adapted to the connecting plate 12. The connecting plate 12 is slidably connected to the female plug 2 through the mounting groove 13. The threaded rod 11 passes through the female plug 2 to the inside of the mounting groove 13 and is threadedly connected to the female plug 2. The connecting plate 12 is fixedly connected to the first slide rod 14 and the second slide rod 15 respectively.

[0024] In this embodiment, when the first positioning rod 6 and the second positioning rod 10 are simultaneously engaged inside the positioning hole 7 and the limiting hole 9 is aligned with the first slide rod 14 and the second slide rod 15 respectively, rotating the knob 8 causes the threaded rod 11 to rotate, which can move the threaded rod 11 into the female plug 2. The movement of the threaded rod 11 causes the connecting plate 12 to slide along the inner wall of the mounting groove 13. The movement of the connecting plate 12 causes the first slide rod 14 and the second slide rod 15 to move simultaneously, so that the first slide rod 14 and the second slide rod 15 can simultaneously extend into the limiting hole 9, improving the convenience of fixing the male plug 1 and the female plug 2. Reverse rotation of the knob 8 can cause the first slide rod 14 and the second slide rod 15 to move in the opposite direction and simultaneously disengage from the inner wall of the limiting hole 9, making it convenient to separate the male plug 1 and the female plug 2.

[0025] The working principle of this utility is as follows: When the male plug 1 and female plug 2 are inserted, the plug block 4, the first positioning rod 6, and the second positioning rod 10 are aligned with the slot 5 and the two positioning holes 7, respectively. When the plug block 4 is engaged inside the slot 5, the first positioning rod 6 and the second positioning rod 10 are simultaneously engaged inside the positioning holes 7. The contacts on the plug block 4 and the slot 5 make contact with each other and conduct current or signal. At this time, the limiting holes 9 are connected to the first sliding groove 16 and the second sliding groove 17, respectively. The limiting holes 9 are aligned with the first sliding rod 14 and the second sliding rod 15, respectively. Rotating the knob 8 causes the threaded rod 11 to rotate, which moves the threaded rod 11 into the female plug 2. The movement of the threaded rod 11 causes the connecting plate 12 to move along the mounting... The inner wall of groove 13 slides, and the connecting plate 12 moves, causing the first slide rod 14 and the second slide rod 15 to move simultaneously. This allows the first slide rod 14 and the second slide rod 15 to simultaneously extend into the limiting hole 9, improving the convenience of fixing the male plug 1 and the female plug 2. The first slide rod 14 and the second slide rod 15 extending into the limiting hole 9 can prevent the first positioning rod 6 and the second positioning rod 10 from continuing to move, thereby fixing the relative position of the male plug 1 and the female plug 2 and preventing them from loosening. Rotating the knob 8 in the opposite direction can cause the first slide rod 14 and the second slide rod 15 to move in the opposite direction and simultaneously disengage from the inner wall of the limiting hole 9, making it easy to separate the male plug 1 and the female plug 2.
