Working principle: in the using process of the device, an operator firstly installs the current action protector;
the operator dials the first clamping block 4 or the second clamping block 3, the first clamping block 4 or the second clamping block 3 can press the sliding block 24 to move, the other surface of the sliding block 24 can further press the pressure spring 22 to compress, when the operator loosens hands, the pressure spring 22 can rebound rapidly, the sliding block 24 is tightly propped, the first clamping block 4 and the second clamping block 3 are clamped on the installation hanging frame in the electrical cabinet, and simple fixation is provided for the current action protector;
when the first clamping block 4 and the adjacent second clamping block 3 are clamped on the mounting rack in the electrical cabinet, an operator can pull the rotating arm 42 out of the first storage groove 41 by pulling the rotating arm 42, the sliding arm 43 can be completely inserted into the sliding groove 421 in the rotating arm 42 during storage of the rotating arm 42, the total length of the rotating arm 42 and the sliding arm 43 is smaller than the width of the first storage groove 41, the sliding arm 43 is inserted into the rotating arm 42 during storage, the rotating arm 42 is fixed on the inner wall of the first storage groove 41 through the magnetic attraction block 412, when the rotating arm 42 is pulled, the operator can pull the sliding arm 43 out of the rotating arm 42 and simultaneously the rotating arm 42 continuously deflects, finally the operator hangs a hook 44 arranged at one end of the sliding arm 43 on a connecting rod 62 at one side of the moving block 6, so that the first clamping block 4 and the second clamping block 3 are combined into a whole, however, the first clamping block 4 and the second clamping block 3 are not completely locked, so that the current action protector can move on the mounting rack inside the electrical cabinet, when the connecting rod 62 moves to the arc-shaped groove 312 area at the top of the inner wall of the moving groove 311 along with the moving block 6, the first clamping block 4 and the second clamping block 3 are still integrally connected, and even if the current action protector is loose, the current action protector cannot fall down due to the fact that the sliding arm 43 pulls the connecting rod 62 vertically upwards to enable the moving block 6 to be inserted into the arc-shaped groove 312, and further the first clamping block 4 and the second clamping block 3 are completely locked and cannot move on the mounting rack inside the electrical cabinet, and when the current action protector is replaced outside, an operator only needs to take the moving block 6 out of the arc-shaped groove 312;
when the rotating arm 42 is separated from the first accommodating groove 41, the rotating arm 42 pulls the first steel cable 53 to move, when the first steel cable 53 moves, the first sleeve 52 is pulled to rotate, and when the first sleeve 52 rotates, the first top plate 521 is driven to rotate, so that the rotating arm is propped against one side of the inner wall of the hanger inside the electrical cabinet, and the fixing effect of the current action protector is further improved;
when the movable block 6 is inserted into the arc-shaped groove 312, the first clamping block 4 and the second clamping block 3 are completely locked and cannot move on the installation hanging frame in the electrical cabinet, when the current action protector is changed outside, an operator only needs to take out the movable block 6 from the arc-shaped groove 312, the first clamping block 4 and the second clamping block 3 are still integrally connected, even if the current action protector is loose, the problem of falling and destruction cannot occur, when the operator needs to take down the current action protector, the operator only needs to take down the hook 44 from the connecting rod 62, and then the current action protector can be taken down, so that the electric cabinet is simple and quick.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
