Two grooves are formed in one side, facing the wire inlet, of the protection box 51, and the positions of the two grooves correspond to the two bottom clamping pieces 52 respectively.

The working principle is as follows:

when the plug is used, a metal sheet of a plug is inserted into the panel box 13 through the hole 65, the knob 28 is pulled upwards manually, the bearing plate 35 is driven to ascend, the clamping rod 39 is driven to ascend to a position higher than the plug through the fourth shaft 37, the knob 28 is rotated again and drives the third gear 30 to rotate, the fourth gear 40 on one side is driven to rotate through gear meshing, the fourth gear 40 on the other side is driven to rotate reversely through reversing transmission of the idler wheel 36, the clamping rods 39 on two sides are driven to rotate to the position above the plug in different rotating directions, the spring 38 is compressed in the process of pulling the knob 28 upwards, the pulling force on the knob 28 is released, the clamping rods 39 on two sides tightly press the plug on the panel box 13 under the elastic force of the spring 38, meanwhile, the rotation of the fourth shafts 37 on two sides drives the driving rods 29 on two sides to rotate, and the driving rods 45 push the conducting strips 45 to rotate after the driving rods 29 are rotated to abut against the conducting strips 45, and then make conducting strip 45 and metal sheet of the plug closely adhere to each other, and then reduced the contact many times of plug metal sheet and conducting strip 45, avoided the production of electric spark, lengthened the life of the socket.

After the use, firstly the knob 28 is rotated until the clamping bar 39 returns to the initial state, then the knob 28 is loosened, when the knob 28 loses the external force, the knob 28 is reset due to the action of the spring 38, meanwhile, the poking rod 29 loses the acting force on the conductive sheet 45, the conductive sheet 45 returns to the original state under the action of the compressible 46, and at the moment, the plug is pulled out.

When the load is too large and the temperature in the panel box 13 is too high, the filler 25 is heated and expanded to push the sliding plate 26 downwards, due to the loss of the connection between the pin 24 and the sliding plate 26, the spring 23 drives the first shaft 22 to rotate, and then drives the first gear 21 to rotate, the first gear 21 drives the second gear 18 to rotate through gear engagement, the second gear 18 rotates to drive the threaded rod 15 to rotate, because the threaded sleeve 16 is fixed, the threaded rod 15 is caused to ascend, and then the second shaft 60 ascends, and further the top clamping piece 19 is far away from the bottom clamping piece 52, and further the clamping on the line is released, meanwhile, the fifth gear 53 rotates and moves synchronously with the second shaft 60, when the fifth gear 53 moves to be engaged with the rack 54, the fifth gear 53 drives the rack 54 to move, and further drives the protection box 51 to move, and further the line inlet is sealed, external wire can break away from and is compressed tightly between protective box 51 and space 12 inner wall from bottom clamp piece 52 under protective box 51's promotion this moment, and then when realizing the outage, because the zero line and the live wire of external wire are in the position of difference, when protective box 51 removes the in-process, separate the protection with the live wire and the zero line of external wire respectively through two grooves in protective box 51, will follow the external wire that the inlet wire got into and isolate the protection, avoid external wire short circuit.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
