The upper end of the terminal rod of the jaw section is provided with a threading hole, and the current wire and the voltage line pass through the threading hole to connect to the current signal groove and the voltage signal groove respectively; the outer surface of the threading hole is covered with a shielding net, connected to the shielding wire, and the inner wall of the threading hole is insulated; The other ends of the line and the voltage line are respectively connected to the upper jaw and the lower jaw;

An alarm device is installed on the upper end of the jaw section; a fixed pulley is installed on the side of the jaw, and a soft stretch wire is wound on it. One end of the soft stretch wire is connected to the lower jaw, and the other end is connected to the hard stretch plate. fixed on the terminal rod connected with the jaw section;

The upper end of the terminal rod is provided with two wiring lead-out holes, one is the current line hole, the other is the voltage line hole, and the two wiring lead-out holes are respectively connected with the current signal groove and the voltage signal groove; the middle part is equipped with an insulating shed, and the lower part is For insulated handles.

Further, the serial connection of multi-section terminal rods refers to that the upper terminal rods are sleeved in the lower terminal rods.

The invention has the advantages of changing the original two tools into one, which is convenient for test operation and improves work efficiency; it can be made of resin material, light in weight and cheap in price, and is suitable for processing models; it is easy to assemble and reduces the work intensity of operators. smaller.
