Lower end and combine arm 20 with what the left lever arm 22 and right lever arm 21 were fixedly connected, the left lever arm 22 is close to the circle
Be provided with ratcheting item 220 on the end face of shape wiring rotary head 30, the 30 left side outer end face of circle wiring rotary head be provided with it is described
Ratcheting item 220 ratcheting teeth section 300 is provided with the slot 31 that is connected of beginning on the lower, the phase in the circle wiring rotary head 30
It is fixedly installed signal in connection slot 31 and receives column 32, the joint arm 20 is close to being provided with round edge on the end face for being connected slot 31
Slot, be equipped in the round edge slot abutted with the beginning for being connected slot 31 be tamping piece 201, the piece 201 that is tamping will be to will
The beginning for being connected slot 31 is blocked, and the via hole 210 that left and right is connected, the shell 10 are provided on the right lever arm 21
On be provided with the jack 110 for connecting the loose slot 100, be provided with elastic-friction piece 111, the elasticity in the jack 110
Friction plate 111 is inserted into the frictional force being connected when in slot 31 between tone frequency channel wire and jack 110 for increasing tone frequency channel wire, prevents audio
Line accidentally slips out, and 20 bottom of joint arm is also equipped with movable drawing article.
Valuably, the movable drawing article includes the screw thread socket 42 for being fixedly mounted on joint 20 bottom of arm, described
Screw thread socket 42 is expanded downward and is pushed into the groove 101 being set in 100 bottom wall of loose slot, and the screwed pipe
It is threadedly engaged in cylinder 42 and moving screw 41 is installed, 41 lower end of moving screw and the electricity being fixedly installed in the shell 10
40 connection of favourable turn.
Valuably, the interval of the via hole 210 to joint 20 bottom wall of arm is equal to the jack 110 to the loose slot
The interval of 100 bottom walls, so that the via hole 210 is located at same with the jack 110 in the adjustable shelf activity to lowermost end
On horizontal line.
Valuably, length of the length in the adjustable shelf in a longitudinal direction of the loose slot 100 in a longitudinal direction
Difference be equal to a quarter of round 30 outer perimeter of wiring rotary head, thus being capable of band when the adjustable shelf activity to lowermost end
Moving the round wiring rotary head 30, fortune is turn 90 degrees counterclockwise, and is located at the slot 31 that is connected with via hole 210 and the jack 110
In same horizontal line.
Valuably, the groove width of the via hole 210 surmount or equal to the jack 110 groove width, thus in the adjustable shelf
Allow tone frequency channel wire to be inserted into the loose slot 100 and receive column 32 with the signal when activity to lowermost end to cooperate.
When original state, the adjustable shelf is located at 100 upper end of loose slot, the beginning vertical court of the slot 31 that is connected
Under, and abutted with the piece 201 that is tamping, at this point, the via hole 210 is located at 110 upper end of jack, thus the right lever arm
21 block the jack 110；
When needing using loudspeaker, start the electricity favourable turn 40, the electricity favourable turn 40 drive the moving screws 41 into
Row operating, so that the screw thread socket 42 is driven to move downward, and the screw thread socket 42 drives the adjustable shelf movable downward,
