As shown in fig. 1 to 8, the handle 22 and the pressing rod 21 are connected to each other by a pivot structure 23, a holding protrusion 221 extends from one side of the handle 22, an elastic arm 222 extends from the other side of the handle 22, the holding protrusion 221 and the pressing protrusion 211 are disposed opposite to each other, the elastic arm 222 can selectively abut against the stopping portion 212, that is, the elastic arm 222 can abut against or be away from the stopping portion 212. The handle 22 may be made of plastic or metal, so that the outwardly extending elastic arm 222 has a certain elasticity.
As described in detail below, the elastic arm 222 can be inserted into the through slot 213 and selectively abut against the stopper 2141, i.e., the elastic arm 222 can abut against or be away from the stopper 2141.

In addition, if the terminal block 1 does not belong to the PID terminal block, the handle 22 pivots toward the terminal block 1, and also drives the pressing arm 211 and the holding arm 221 to move closer, so that the pressing portion 121 is pressed toward the inner direction of the deep penetrating slot 114, at this time, the pulling member 12 presses against the resilient piece 14, so that the resilient piece 14 swings downward to open the slot 111, and the cable 100 is inserted into the open slot 111 and electrically connected to the conductive terminal 13.
Finally, as shown in fig. 7, the force applied by the handle 22 to pivot toward the terminal block 1 is cancelled, that is, the handle 22 pivots away from the terminal block 1, so that the pressing arm 211 and the holding arm 221 are away from each other, the downward pushing force originally borne by the elastic piece 14 is eliminated, the elastic piece 14 swings upward to return to the original position, and the slot 111 needs to be closed, but since the cable 100 is inserted into the slot 111, the elastic piece 14 is stopped by the cable 100, and the cable 100 is clamped and positioned between the inner wall of the slot 111 and the elastic piece 14.
As shown in fig. 5 and 8, the pressing portion 121 has a groove 1211, and the first locking tongue 2111 of the pressing arm 211 and the second locking tongue 2211 of the holding arm 221 are respectively fitted into the groove 1211, so that the wire handle 2 can be more tightly engaged with the pressing portion 121, and the wire handle 2 has a function of more reliably pressing the pressing portion 121.
Moreover, the wiring handle 2 of the present invention can be used in a forward direction or a reverse direction, which can achieve the above-mentioned operational relationship and effects. As shown in fig. 5, the pressing arm 211 presses against the pressing portion 121, the holding arm 221 presses against the holding portion 113, and the first latch 2111 of the pressing arm 211 is engaged with the groove 1211, so that the wiring handle 2 is fastened to the terminal block 1 in a forward use manner; as shown in fig. 8, the pressing arm 211 presses against the holding portion 113, the holding arm 221 presses against the pressing portion 121, and the second locking tongue 2211 of the holding arm 221 is engaged with the groove 1211, so that the wiring handle 2 is fastened to the terminal block 1 in a reverse use manner.
