On the inwall of pole, described fixed tilted supporter is divided into four groups, and the angle of per group of fixed tilted supporter is 90 degree, solid by four groups
Determining tilted supporter carries out positioning restriction to the four direction of conductive devices, and more comprehensively conductive devices can be fixed, and prevents
Only occur loosening and rocking.
Preferably, described spiral is fixed the edge of teeth and is set to circular arc edge, the shape of described fixing groove and rotation
The shape for turning fixed teeth is corresponding, by circular arc edge arcuate structure, by increasing capacitance it is possible to increase the fixed teeth of rotation and fixing groove it
Between contact area, increase frictional force, placement come off in use, increase bonding strength.
Preferably, between described fixed tilted supporter and the circular shaft of conductive devices it is in 60 degree of angles, can be horizontal and vertical
To carry out it is two-way limited by position, improve degree of fixation.
