By the way that third lead-out wire 330 and the 4th lead-out wire 340 to be connected on the second support base 500, i.e., on the second support base 500
Interval setting third wire lead slot 510 and the 4th wire lead slot 520, and through third lead-out wire 330 and the 4th lead-out wire 340 respectively with
Third wire lead slot 510 and the socket of the 4th wire lead slot 520, when assembling, between third lead-out wire 330 and the 4th lead-out wire 340
It is isolated from each other, and during use, under the constraint of third wire lead slot 510 and the 4th wire lead slot 520, third lead-out wire
It 330 and the 4th will not relatively move between lead-out wire 340, avoid between third lead-out wire 330 and the 4th lead-out wire 340
Close to each other or even contact situation occurs, thus compared with the existing technology, it is only necessary to which two leads hang angle, that is, can guarantee and use
Stability, preferably solve in the prior art because needing to be spaced the skill for being arranged and causing occupied space big due to four leads hang angle
Art problem, and then the occupancy in space can be further decreased.
