Background
In recent years, people have higher and higher requirements on power supply reliability, construction and urgent repair time are shortened by methods for power enterprises so as to guarantee continuous power supply to customers, a quick wiring device is frequently used for carrying out emergency power supply or grounding on cables to be repaired in power system construction, and the currently commonly used quick wiring devices mainly have two types: screw-hold and spring-hold, each having their own advantages and disadvantages. The screw-in contact surface is secure but has a long operating time. The spring compression type greatly shortens the operation time, but the problem that the contact surface is not fastened reliably can occur due to the problem of spring aging. Therefore, at present, many quick wiring devices are in a spiral compression type, but the mode is that an operator rotates an insulating rod, so that a wire clamp part of the quick wiring device clamps a wire along with the upward movement of a bolt, and the line spacing of an opening of the wire clamp is nearly 6-8CM, so that the time for rotating and screwing or unscrewing is too long in the operation process of screwing the wire clamp to clamp the wire or unscrewing the wire clamp to withdraw from the operation process of screwing the wire clamp to withdraw from the wire, and nearly more than half of the line spacing is an invalid stroke, so that the labor intensity of maintenance operators using the spiral compression type quick wiring device is high, the operation is very inconvenient, the assembly and disassembly efficiency is low, and time and labor are wasted.
