Description

Universal fastening clamp

technical field

The utility model relates to the field of electric tools, in particular to a universal fastening clip.

Background technique

It is very important to ensure the safe and stable operation of the power grid in today's society. The cable is erected on the pole or building through the street yard. The fixing of the cable end is generally to bend the cable end around the street yard and then bend it Bundle or fix the separated cables under tension; at present, construction workers usually use traditional methods such as manpower or simple tools to compress the separated cables together, and then use binding wires to bind and fix the compressed cables. The binding wires are generally thin aluminum metal wires. Tightening the cables will reduce the insulation of the cables and easily cause damage to the outer layer of the cable insulation. Moreover, there is no uniform standard for the binding method, which is very random, resulting in the firm binding of the cable ends. It is difficult to guarantee the safety, and the cable end is easy to loosen and fall off from the street yard, which brings potential safety hazards.

The existing technology has improved the traditional cable binding method by using clamps to fix the cables, but these clamps are generally only suitable for cables with a certain diameter range, and the large clamps used to fix thick diameter cables are difficult to fix thin diameter cables. Conversely, the small clamps used to fix thin-diameter cables are also difficult to fix thick-diameter cables, and the range of use of the clamps is limited, so that operators need to carry different sizes of clamps to adapt to cables of different diameters, and even use them with clamps Different types of tightening tools should be equipped accordingly, which is extremely inconvenient for operators working at heights.
