The utility model is further arranged to：Head includes convex arc ring, and afterbody is equipped with concave arc groove and convex arc platform, connecting portion
It is equipped with opening and is against the slot bottom of concave arc groove towards the U-type groove outside bending section, convex arc ring, convex arc platform is arranged to cambered surface, convex arc platform
With U-type groove clearance fit.
By using above-mentioned technical proposal, the head and the tail connection of two neighboring bending section is realized, the U-type groove of connecting portion is to head
The space of portion's offer activity, after two bools are worked in coordination, convex arc platform and U-type groove clearance fit, cambered surface make contact surface by
Power is uniform, and connecting portion is the component that adjacent flex section is connected, and can be that sheath bent when being positioned over mating connection in afterbody
When certain bending effect is provided.
The utility model is further arranged to：Dirt-proof boot is arranged with bending section, one end of dirt-proof boot is embedded in adapter
Portion.
By using above-mentioned technical proposal, the setting of dirt-proof boot, prevents dust impurity etc. from entering the connection of adjacent flex section
Place influences the activity of bending section, prevents power cord from fractureing indirectly.
The utility model is further arranged to：Convex arc ring is equipped with damping slot and some damping balls, and damping ball, which is embedded, to be hindered
In Buddhist nun's groove, damping ball is abutted with concave arc groove.
By using above-mentioned technical proposal, when afterbody is movable in head, it is embedded in damping slot internal damping ball on head
It is in rolling contact in concave arc groove, avoids bending section from being given a shock and voluntarily rotate, when adjacent flex section is movable, damping ball plays necessarily
The effect of prevention activity.
The utility model is further arranged to：Dirt-proof boot is hollow round table backwards to one end of adapter.
By using above-mentioned technical proposal, dirt-proof boot can effectively wrap up power cord backwards to one end of adapter, prevent ash
Dirt enters the gap of power cord and dirt-proof boot.
Compared with prior art, the utility model prevents adapter and power cord junction because of overbending and fatigue is rolled over
It is disconnected, so as to prolong the service life.
