For this purpose, no further description is made in the present invention. As mentioned above, the provision of the first connection lever opening 1513 and the second connection lever opening 1514 enables the handle 151 to be used for sensing the switch function of the current interrupt device with action using residual electric current 100 and may also find use for realizing the repositioning function , The opening 1517 is basically formed on the left side of the wheel body 1511 (when the handle 151 in the in Figure 4 shown position). When the handle 151 is mounted in the mounting groove for the handle 1210, the male portion 1216 of locking piece 1212 can be inserted into the aperture 1517, and upon rotation of handle 151, the male portion 1216 of blocking piece 1212 can make a sliding movement along the aperture 1517 to limit the rotation of handle 151.

The first end of the first link lever 152 is provided by a hinge joint in the first link lever opening 1513, while the second end of the first link lever 152 is connected to the repositioning lever 153 by a hinge connection, so that the handle 151 via the first link lever 152 to the repositioning lever 153 Can drive movement.

As shown in FIG Figure 5 As shown, the repositioning lever 153 includes a body 1531, a connecting part 1532, and a repositioning part 1533. The body 1531 basically has an arcuate shape, and a mounting hole 1534 is provided at the middle part. Through hinge hinge axis 170 provided in mounting aperture 1534 (as shown in FIGS. 1 and 2), body 1531 is rotatably mounted to base base 122. On the body 1531, a first smooth protruding ledge 1535 and a second smooth protruding ledge 1536 are also provided. The first smooth protruding ledge 1535 and the second smooth protruding ledge 1536 are provided on the body 1531 in a non-symmetrical manner.

The base body 1541 has basically an arc shape, wherein in the middle part of a mounting opening 1544 is provided. Attached to hinge hinge axis 170 of mounting aperture 1544 (as shown in FIGS. 1 and 2), base body 1541 is rotatably mounted on base base 122 and is in contact with repositioning lever 153. Because the first smooth protruding ledge 1535 and the second smooth protruding ledge 1536 are provided on the repositioning lever 153, the friction between the repositioning lever 153 and the release lever 154 can be largely minimized. In addition, in the middle part of base body 1541, the extension arm 1545 is formed, with the extension arm 1545 being basically vertically provided on the base body 1541, and on the extension arm 1545 further forming the connection bump 1546 which serves to connect to the elastic compression member 156.

As shown in Figs. 1 and 3, the elastic compression member 156 comprises a compression spring. The first end of the elastic compression member 156 is connected to the connection piece 1546 located on the release lever 154. The second end of the elastic compression member 156 may be connected to the elevation plate 1225 located above the base pedestal 122. In order to protect and restrict the direction of movement of the elastic compression member 156, the elastic compression member 156 may further comprise a position limiting plate provided above the base socket 122, which abuts the elevation plate 1225 is provided and surrounds the compression spring.

The explanation given above was for the description of the construction of the current interrupt device with action using residual electric current 100. The explanation of the use procedure is given below. As in illustration 1 As shown, the current interruption device is in action using residual electric current 100 in the first state, for example, the closed state. Here, the second end of the first connecting lever 152 is located at the upper part of the connecting groove 1539 of the repositioning lever 153, and exerts no action on the repositioning lever 153 toward the elastic repositioning member 155. The first working surface 1537 of repositioning lever 153 is in the initial position, for example, in contact with the upper lever 132 of the release device 130.

As in Figure 2 As shown, the current interrupt device is in action using residual electric current 100 in the second state, for example, the opened state. During the transition of the current interrupt device to action using residual electric current 100 from the first state to the second state, the second end of the first link lever 152, in the course of the rotation of handle 151, makes a sliding downward movement in the communication groove 1539 of repositioning lever 153 (FIG the current interruption device reacts with action using residual electric current 100 in the in Figure 2 1) until abutting the lower part of the connecting groove 1539 of repositioning lever 153 and applying pressure to the repositioning lever 153 and the elastic repositioning member 155 so that the elastic repositioning member 155 compressively stores energy, the repositioning lever 153 at the same time as the axis of rotation about a movement of the hinge axis 170 in a first direction, for example in the counterclockwise direction, until the first working surface 1537 of the repositioning lever 153 leaves the initial position. When the current interrupt device with action using residual electric current 100 is in the second state, for example, the opened state, the release device 130 can operate the second work surface 1547 of release part 1543 when operating with relatively little force to realize the release function. When the current interruption device with action using residual electric current 100 is in the second state, for example, the opened state, the elastic repositioning element 155 is guided in the direction of the action of the repositioning lever 153 on the first connecting lever 152 through the center of rotation of the handle 151 sure that the handle 151 is not turned back.

Upon completion of the release, the repositioning device 150 assists the release device 130 in performing the repositioning so that the current interrupt device with action using residual electric current 100 is again in the first state. Here, the second end of the first linkage lever 152 in the course of the rotation of the handle 151 makes a sliding upward movement in the connection groove 1539 of the repositioning lever 153 (when the current interruption device takes action with use of residual electric current 100 in the in illustration 1 12), so that the pressure applied to the repositioning lever 153 and the elastic repositioning member 155 is gradually reduced until the elastic repositioning member 155 moves the repositioning lever 153 to move in a second direction, for example, in the direction of FIG Clockwise, drives the hinge joint axis 170 as the axis of rotation and the first working surface 1537 of the repositioning lever 153 returns to the initial position and thus the first work surface 1537 drives the upper lever 132 of the release device 130 and provides support of the release device 130 in the realization of the repositioning function.

Further, in the course of driving the repositioning lever 153 to rotate by the elastic repositioning member 155, the first protrusion 1226 and the second protrusion 1227 provided on the base pedestal 122 may restrict the transitional movement of repositioning lever 153 under the action of the elastic repositioning member 155 to prevent deterioration the position of release lever 154 takes place. When the current interrupt device with action using residual electric current 100 is in the first state, the first elevation 1226 and second elevation 1227 provided on the base pedestal 122 should be at the tuning gap of repositioning lever 153 and release lever 154. In addition, it is provided that in the course of the rotation of handle 151 of the second connecting lever 160 is movable according to the conventional manner, which requires no further explanation at this point.

at Figure 7 it is the representation of the current interrupt device with action using residual electric current 100a. The current interrupt device with action using residual electric current 100a is similar to the current interrupt device with action using residual electric current 100. The difference is mainly in the concrete construction of repositioning lever and release lever. at Figure 8 it is the representation of the concrete construction of repositioning lever 153a and release lever 154a of Power interrupt device with action using residual electric power 100a. As in Figure 8 shown repositioning lever 153a / release lever 154a basically coincide with repositioning lever 153 / release lever 154. The main difference is as follows: The first work surface 1537a of the repositioning part 1533a of the repositioning lever 153a is located on the rear side of the release part 1543a of the release lever 154a, and the release lever 154a is located between the first work surface 1537a and the upper lever 132 of the release device 130. In this way, in the course of the repositioning, the first work surface 1537a drives the third work surface 1549a (the surface opposite to the second work surface 1547a) of the release part 1543a of the release lever 154a, so that the second work surface 1547a of the release part 1543a of the release lever 154a drives the upper lever 132 the release device 130 and provides assistance in realizing the repositioning function. In other words, the second work surface 1547a is involved in both the process of release and the process of repositioning, while the first work surface 1537a is indirectly involved in the process of repositioning.

at Figure 9 is the representation of the current interrupt device with action using residual electric current 100b according to another practical embodiment of the present invention. The current interrupt device with action using residual electric current 100b is similar to the current interrupt device with action using residual electric current 100. The difference is mainly in the concrete construction of the repositioning lever and the release lever. As shown in FIGS. 10 and 11, the first connection lever opening 1513b is an elongated opening Central part for regulating the movement, while it is the connecting groove 1539 b is a circular opening, which serves the power transmission.
