Example 2: the rest of the structure of the present embodiment is as described in embodiment 1, except that:
as shown in fig. 2, 3 and 4, the portable bus bar clamp further comprises a linkage type conductive locking rod stopping device 9.
The linkage type conductive locking rod stopping device comprises a plurality of limiting grooves 9.1 which are circumferentially and uniformly distributed on the outer side surface of the conductive locking rod, a fixed plate 9.2 and a floating plate 9.3 which are arranged in an insulating box, a guide through hole which is arranged on the fixed plate, a guide rod 9.5 which is arranged in the guide through hole in a sliding manner and is connected with the floating plate, a limiting stop block 9.4 which is arranged on the floating plate and is matched with the limiting grooves, a guide sleeve 9.7 which is arranged on the insulating box and is parallel to the guide rod, and a linkage ejector rod 9.8 which is arranged in the guide sleeve in a sliding manner.
The limiting groove is close to the second end of the conductive locking rod, and the length direction of the limiting groove is parallel to the axis of the conductive locking rod.
The fixed plate is parallel to the floating plate. The floating plate is parallel to the axis of the conductive locking rod. The floating plate is positioned between the fixed plate and the conductive locking rod. A compression spring 9.6 is sleeved on the guide rod and positioned between the fixed plate and the floating plate.
The linkage ejector rod is parallel to the axis of the insulating cable sheath. The linkage ejector rod is vertical to the floating plate. The linkage ejector rod and the fixed plate are positioned on two opposite sides of the floating plate. The first end of the linkage ejector rod is located in the insulation box, and the second end of the linkage ejector rod is located on the outer side of the insulation box.

The inventor finds that in the third step of embodiment 1, the problem that the insulating cable sheath is not locked in place, even the insulating cable sheath is not mounted on the connecting pipe of the insulating box, so that the wire core at the end of the low-voltage cable and the joint of the cable connecting terminal are exposed outside, and therefore the joint of the wire core at the end of the low-voltage cable and the cable connecting terminal is easily damaged, and more importantly, the potential safety hazard of electric shock of personnel exists.

In this way, in the fourth step of embodiment 1, "the conductive locking rod is rotated by matching the hexagon socket wrench and the hexagon socket recess", and the busbar is clamped in the jaw by the conductive chuck;
if the insulating cable sheath is not locked in place, even if the insulating cable sheath is not installed on the connecting pipe of the insulating box: the spacing stop block and the spacing groove are still in a matching state, so that the operation of rotating the conductive locking rod by matching the inner hexagonal wrench and the inner hexagonal groove in the fourth step of embodiment 1 cannot be smoothly performed, namely, the inner hexagonal wrench cannot rotate the conductive locking rod, at this time, an operator is reminded that the insulating cable sheath is not locked in place, the insulating cable sheath needs to be installed in place, the insulating cable sheath can be installed in place daily, the problem that the insulating cable sheath is not locked in place and even the insulating cable sheath is not installed on a connecting pipe of an insulating box is solved, the wire cores at the end part of the low-voltage cable and the joints of the cable connecting terminals are exposed outside, the wire cores at the end part of the low-voltage cable and the joints of the cable connecting terminals are easy to damage, and the problem of potential safety hazard of electric shock of personnel exists.
