The further setting again of the utility model: connecting sleeve is being equipped with extension far from switch head side, described
Flexible deformation can occur for extension.
Using above-mentioned setting further again, the extension can occur therewith flexible deformation in electric wire bending, wear
If one section of electric wire bending of extension and extension side contradict, so that the active force of electric wire bending is dispersed on extension, electricity
Line is integrally hardly damaged.
The further setting again of the utility model: extension is wound around electric wire periphery, the internal orifice of extension in the shape of a spiral
Diameter is gradually reduced from one end close to switch head to the other end, and extension is along the thickness of the hand of spiral also by close to switch head
One end is gradually reduced to the other end.
Using above-mentioned setting further again, flexible deformation occurs convenient for extension.
The further setting again of the utility model: the outer peripheral surface of the connecting sleeve is arranged in polygon.
Using above-mentioned setting further again, convenient for carrying out hand-held to connecting sleeve.
The further setting again of the utility model: the extension is made of rubber.
Using above-mentioned setting further again, flexible deformation effect is good, and wearability is more preferable；It is anti-aging, corrosion resistance is strong.
