[0033] The working principle of this utility model:
[0034] When sealing protection is performed, the sealing cover 41 is closed by rotating counterclockwise. At the same time, the sealing cover 41 rotates and drives the rotating block 433 to rotate on the surface of the rotating shaft 432 in the rotating seat 431. As the rotation is closed, the connecting head 44 is driven to be inserted into the shell 51, squeezing the two clamping heads 522, so that the two clamping heads 522 are squeezed and move to the upper and lower ends. When the clamping heads 522 move, the moving rod 521 is driven to move toward the outside of the shell 51, and the spring 523 is squeezed at the same time. After the sealing cover 41 is completely rotated and closed, the position of the connecting head 44 no longer squeezes the clamping heads 522. At this time, the spring 523 will rebound and push the two clamping heads 522 together to clamp the connecting head 44, thereby closing and fixing the sealing cover 41. For sealing protection, when the device is to be opened for subsequent use, the button 544 is pulled backward to drive the moving block 542 to move backward on the surface of the support rod 541. While the moving block 542 moves, it drives the two pressure rods 543 to move in the two grooves 534, and moves and squeezes the inner walls of the grooves 534, so that the two connecting parts 532 are squeezed on the surfaces of the two rotating rods 531, and the front ends rotate away from each other with the rotating rod 531 as the center, and at the same time drives the two push rods 533 to move in the two travel grooves 524, and moves and squeezes the inner walls of the travel grooves 524, so that the two clamping heads 522 are squeezed and move up and down, so as to release the clamping of the connecting head 44 and the fixation of the sealing cover 41, and then rotate the sealing cover 41 clockwise to open it.
