Portion, 112 height and position of column is fixed at this time, can be defined as column 112 and is adjusted to low level.In fact, due to miniature antenna
Bracket 100 is whole to be made of nonmetallic materials, therefore the anchor ear power that the first fastening screw 120 generates is not enough to support post 112
Free position is rested on, because still suffering from the weight of all buildings on column 112.Therefore the first fastening screw 120 only limits
Itself axially rotating for column 112, is cooperated by convex block 121 and groove 122, is fixed on column 112 high-order or low
Position.
Preferably, being also provided with ring recess 125 on the outer wall of column 112.Ring recess 125 is connected to short slot 124 and elongated slot 123,
Convex block 121 is set to switch movement between elongated slot 123 and short slot 124 by ring recess 125.It is readily comprehensible, when needing to adjust column 112
When height, without allowing column 112 to be detached from casing 111, convex block 121 can be made to cut between long and short slot 123,124 by ring recess 125
It changes, to adjust 112 height of column.For example, suitably being unscrewed on the first fixing piece 117 when column 112 can be fixed on low level
First fastening screw 120.It is lifted up column 112, when convex block 121 is moved down into 125 position of ring recess in elongated slot 123,
Axis rotation height along column 112 adjusts ring 116, slides into convex block 121 in short slot 124 by elongated slot 123, under column 112
It moves, convex block 121 moves relatively upward in short slot 124 and cooperates with the top of short slot 124 and fixes.In this way, complete convex block 121 by
Elongated slot 123 is transferred in short slot 124, i.e., column 112 is adjusted to high-order by low level.Conversely, convex block 121 can also be by short slot 124
It is transferred in elongated slot 123, then column 112 is adjusted to low level by a high position.
Preferably, diametrically upper equipped with inwardly projecting convex of opposite two on the inner wall of height adjustment ring 116
Block 121.4 grooves 122 are offered along its axial direction on the outer wall of column 112, it is opposite including 2 opposite elongated slots 123 and 2
Short slot 124, elongated slot 123 and short slot 124 are staggered 90 degree each other.
Preferably, the surface protruding upward in height adjustment ring 116 of convex block 121, the top of convex block 121 is arc-shaped.Together
Sample, the inside top of elongated slot 123 and short slot 124 is arc-shaped.The top of convex block 121 and the top of elongated slot 123 and short slot 124
Cooperation is fixed, and be bonded to each other the two can, good fixing effect.
Preferably, the area of section of the first, second, third mobile bar 103,104,105 is sequentially reduced, accordingly to mitigate
One, the weight of second, third mobile bar 103,104,105, thus from the whole weight for successively mitigating each component upwards and being supported,
The test miniature antenna 115 of effective support tip.
Preferably, being carved with scale in the first, second, third mobile bar 103,104,105, such as with 1 millimeter for singly
Position, to facilitate adjustment test position.
