[0028] The effect achieved by the entire embodiment 1 is that, when connected, the staff rotates the rotating shaft 12, and the rotation of the rotating shaft 12 drives the threaded rod 6 to rotate, so that the first slider 7 and the second slider 8 approach each other, and then drives the first sealing plate 9 and the second sealing plate 10 to approach each other. When the two sealing strips 16 completely enter the two waterproof grooves 17, the first sealing plate 9 and the second sealing plate 10 can play a sealing effect, and the sealing strip 16 enhances the sealing between the first sealing plate 9 and the second sealing plate 10.
[0029] Embodiment 2, as Figure 1-Figure 6 As shown, further, the two sealing strips 16 are respectively engaged with the two waterproof grooves 17, thereby improving the sealing performance between the first sealing plate 9 and the second sealing plate 10.
[0030] Furthermore, a slot 21 is provided on the opposite side of the two fixing plates 5, and two storage slots 22 are provided on the inner walls of the two slots 21. Second springs 23 are fixedly installed on the inner walls of the two storage slots 22, and a push plate 24 is fixedly installed on one end of the two second springs 23 close to the slot 21.
[0031] Furthermore, a second limiting rod 25 is fixedly installed on one side of the two push plates 24 close to the second spring 23, and one end of the two second limiting rods 25 away from the push plates 24 is slidably plugged into the fixed plate 5 to prevent the push plates 24 from tilting when moving.
[0032] Furthermore, the inner walls of the two storage slots 22 are penetrated with a slide slot 13 , and the two push plates 24 are slidably connected to the two slide slots 13 , respectively. The pull plates 14 are fixedly mounted at one end of the two push plates 24 .
[0033] Furthermore, U-shaped plates 15 are slidably installed inside the two slots 21, and the outer walls of the two U-shaped plates 15 are provided with limiting grooves 18. The inner walls of the two limiting grooves 18 are fixedly installed with first springs 19, and one end of the two first springs 19 is fixedly installed with a clamping block 20.
[0034] Furthermore, the outer wall of the block 20 fits with the inner wall of the storage slot 22 , and the outer wall of the U-shaped plate 15 fits with the inner wall of the slot 21 , so as to prevent the U-shaped plate 15 from tilting.
[0035] Furthermore, a connection port 26 is formed on the outer wall of the shell 1 , and a connector 27 is threadedly connected to the inside of the connection port 26 . A connection plate 28 is fixedly mounted on one end of the connector 27 , and an electric wire 4 is fixedly mounted on one end of the connection plate 28 away from the connector 27 .

[0038] The effect achieved by the entire embodiment 2 is that when connecting, the staff pushes the U-shaped plate 15, the U-shaped plate 15 drives the block 20 to descend, and the inclined surface of the block 20 is connected to the Figure 5 As shown, the block 20 contacts the inner wall of the storage groove 22 above and is squeezed into the limit groove 18. The block 20 continues to move until it moves to the second storage groove 22. At this time, the block 20 enters the storage groove 22 under the elastic force of the first spring 19.

[0039] Working principle: When connecting, the staff connects the connector 27 with the connector port 26, and then rotates the shaft 12. The rotation of the shaft 12 drives the threaded rod 6 to rotate, so that the first slider 7 and the second slider 8 are close to each other, and then drives the first sealing plate 9 and the second sealing plate 10 to be close to each other. When the two sealing strips 16 completely enter the two waterproof grooves 17, the first sealing plate 9 and the second sealing plate 10 can play a sealing effect, and the sealing strip 16 enhances the sealing between the first sealing plate 9 and the second sealing plate 10. Then the staff pushes the U-shaped plate 15, and the U-shaped plate 15 drives the block 20 to descend. The inclined surface of the block 20 is in contact with the Figure 5As shown, the block 20 contacts the inner wall of the storage slot 22 above, is squeezed into the limiting slot 18, and the block 20 continues to move until it moves to the second storage slot 22.
